DETAILED DESCRIPTION
Various non-limiting embodiments of the present disclosure will now be described to provide an overall understanding of the principles of the structure, function, manufacture, and use of the flow restricting apparatuses and connector assemblies for the same disclosed herein. One or more examples of these non-limiting embodiments are illustrated in the accompanying drawings. It will be appreciated that the flow restricting apparatuses and the connector assemblies for the same specifically described herein and illustrated in the accompanying drawings are non-limiting example embodiments and that the scope of the various non-limiting embodiments of the present disclosure are defined solely by the claims. The features illustrated or described in connection with one non-limiting embodiment may be combined with the features of other non-limiting embodiments. Such modifications and variations are intended to be included within the scope of the present disclosure.
In one embodiment, referring to FIG. 1, a flow restricting apparatus or a fluid flow restricting apparatus, such as vortex valve 10, for example, can be used to restrict or slow fluid flow from a reservoir 12 or a drainage gully to an outlet conduit or pipe 14. Although a “vortex valve” is referred to herein, the present disclosure contemplates multiple flow restricting apparatuses or fluid flow restricting apparatuses other than vortex valves, as described in greater detail below. The vortex valve 10 can allow flow therethrough under normal conditions and can create an air vortex therein during high flow conditions to slow or restrict the flow of fluid from the reservoir 12 or the drainage gully into the outlet conduit 14. Such a feature can help protect equipment positioned downstream of the vortex valve 10 from flooding during periods of heavy rainfall or runoff, for example. In one embodiment, the fluid restricted by the vortex valve 10 can be water, such as storm water, for example.
In various embodiments, referring to FIGS. 1-11, the vortex valve 10 can be operatively and/or fluidly associated with the outlet conduit 14 using a connector assembly 16. In one embodiment, the connector assembly 16 can comprise a first member 18 and a second member 20. The second member 20 can receive, be engaged with, and/or be sealably coupled to an end portion of the outlet conduit 14. In one embodiment, a gasket (not illustrated) or other suitable sealing member can be positioned intermediate the second member 20 and the end portion of the outlet conduit 14 to create a fluid-tight, or substantially fluid-tight, connection between the second member 20 and the end portion of the outlet conduit 14. The end portion of the outlet conduit 14 can be engaged with the second member 20 using fasteners, such as anchor bolts, for example. In other embodiments, the second member 20 can be connected to the outlet conduit 14 using other suitable fastening devices or methods known to those of skill in the art. The first member 18 can be engaged with the vortex valve 10. In such an embodiment, fluid from the reservoir 12 or the drainage gully can flow into an inlet 26 of the vortex valve 10, flow through the vortex valve 10, flow through an outlet 28 of the vortex valve 10, flow through a bore 30 in the first member 18, flow through a bore 32 in the second member 20, and flow into the outlet conduit 14. Such a flow sequence can occur independent of whether an air vortex is created within the vortex valve 10. In various embodiments, when assembled, the outlet 28, the bore 30, the bore 32, and an opening in the end portion of the outlet conduit 14 can be in fluid communication or sealed fluid communication, such that the fluid in the reservoir 12 or the drainage gully can flow into the outlet conduit 14. In various embodiments, the vortex valve 10 and the first member 18 can be removably attached to the second member 20 for cleaning of the vortex valve 10, or maintenance to the vortex valve 10, for example. The bores 30, 32 can be the same size (e.g., same radii if the bores are circular) or they can be different sizes. For example, the bore 30 of the first member 18 can be size smaller (e.g., a lesser radius) than the bore 32 of the second member 20. In various embodiments, the size of the bores 30 and 32 can be changed during manufacturing to modify the flow rate of fluid through the connector assembly 16. In one embodiment, if the bores 30 and 32 are larger the flow rate of fluid through the connector assembly 16 can be greater.
In one embodiment, referring to FIG. 1, the reservoir 12 can comprise a side wall 11 having an aperture therein. The aperture in the side wall 11 can receive a portion of the outlet conduit 14 therethrough. The second member 20 can be bolted or otherwise fastened to the side wall 11 over the aperture in the side wall 11. In various embodiments, a gasket 13 can be positioned intermediate the side wall 11 and the second member 20 such that a fluid-tight, or substantially fluid-tight, seal can be made between the second member 20 and the side wall 11.
In one embodiment, referring to FIGS. 2, 3, and 5-13, the first member 18 can comprise a first face 34 and a second face 36. The bore 30 can be defined through the first member 18 at least intermediate the first face 34 and the second face 36. An annular flange or projection 38, or an otherwise shaped flange or projection, can extend from the first face 34 and can be configured to be positioned against, in fluid communication with, about, proximate to, and/or adjacent to at least a portion of the outlet 28 of the vortex valve 10. In one embodiment, a portion of the bore 30 can be defined by the annular flange 38. In various embodiments, a groove 40 can be defined in the second face 36 and the groove 40 can at least partially surround the bore 30 or can fully surround the bore 30. In one embodiment, the groove 40 can comprise an arcuate portion and can have a circular-shaped perimeter. In other embodiments, the groove 40 can comprise a square-shaped perimeter, a rectangular-shaped perimeter, a triangular-shaped perimeter, an ovate-shaped perimeter, and/or any other suitably shaped perimeter. In various embodiments, the first member 18 may not comprise the groove 40 and can comprise other suitable sealing members or materials, such as a gasket, for example. In one embodiment, the first member 18 can comprise a raised lip (not illustrated) extending from the second face 36. The raised lip in the second face 36 of the first member 18 can be provided with or without the groove 40. In one embodiment, both the raised lip and the groove 40 can be used to seal the first member 18 to the second member 20. Other suitable sealing members, such as gaskets or materials, for example, can be used intermediate the various components of the connector assembly 16 as will be recognized by those of skill in the art.
In one embodiment, the first member 18 can comprise an outer edge 42 defining the perimeter of the first member 18. In various embodiments, the outer edge 42 can have a triangular shape, a circular shape, a semi-circular shape, a trapezoidal shape, a truncated trapezoidal shape, a rectangular shape, a square shape, an ovate shape, and/or any other suitable shape. In any event, the outer edge 42 can have a shape configured to at least partially fit within one or more projections or one or more receiving portions on the second member 20. In one embodiment, the first member 18 can comprise one or more tapered or angled portions 44 to aid the engagement of the first member 18 with the second member 20 and/or the engagement of the first member 18 with one or more projections or one or more receiving portions on the second member 20. In other various embodiments, the entire first member 18 can be tapered such that the first member 18 can act as a type of wedge when engaged with the one or more projections or the receiving portions on the second member 20. In one embodiment, the tapered or angled portion 44 can be situated proximate to a point of a triangular first member 18, for example. In such an embodiment, the distance between the first face 34 and the second face 36 at one end of the first member 18 can be greater than the distance between the first face 34 and the second face 36 at the other end of the first member 18. In one embodiment, the tapered portion 44 can be formed in the first face 34 and/or the second face 36.
In various embodiments, the first member 18 can comprise one or more apertures 46 configured to each receive portions of a connection member 52, such as a screw or a bolt, for example, such that the first member 18 can be attached to the vortex valve 10. The vortex valve 10 can comprise apertures 80 configured to receive portions of the connection members 52 therein. The apertures 80 can be positioned on the vortex valve 10 proximate to or about the outlet 28, for example. In one embodiment, the connection members 52 can be threaded and side walls of the apertures 46 and the apertures 80 can comprise threads, for example. As a result, the connection members 52 can be threadably engaged with portions of the apertures 46 and portions of the apertures 80 to affix the first member 18 to the vortex valve 10. In one embodiment, a sealing member or material can be positioned intermediate the first member 18 and the vortex valve 10 to ensure a fluid-tight, or substantially fluid-tight, connection between the first member 18 and the vortex valve 10.
In one embodiment, referring to FIGS. 2, 3, 5-11, 14, and 15, the second member 20 can comprise a first side 60 and a second side 62. The bore 32 of the second member 20 can be defined through the second member 20 intermediate the first side 60 and the second side 62. The bore 32 can be configured to at least partially or fully align with the bore 30 of the first member 18 when the first member 18 is engaged with second member 20. Upon engagement of the first member 18 with the second member 20, the second face 36 of the first member 18 can be positioned adjacent to, or in abutting contact with, the first side 60 of the second member 20. In one embodiment, a raised lip 64, protrusion, projection, or other structure can extend from the first side 60. In one embodiment, the raised lip 64 can comprise an arcuate portion and can comprise a circular-shaped perimeter. In other embodiments, the raised lip 64 can comprise a perimeter, shape, and/or configuration configured to engage the groove in the first member 18. The raised lip 64 can at least partially or fully surround the bore 32. In one embodiment, the raised lip 64 can be configured to sealingly engage the groove 40 when the first member 18 is engaged with the second member 20. In various embodiments, portions of the raised lip 64 and/or portions of the groove 40 can comprise a sealing substance or member, for example. In other various embodiments, the seal between the raised lip 64 and the groove 40 can be made without a sealing substance or member. In an embodiment in which the second face 36 of the first member 18 comprises a raised lip, the first side 60 of the second member 20 can comprise a groove configured to receive the raised lip, or sealing engage the raised lip, for example. In various embodiments, the raised lip and the groove can be shaped and situated to compliment and/or engage each other when one of the raised lip and the groove is positioned on the first member 18 and one of the raised lip and the groove is positioned on the second member 20. In one embodiment, the second member 20 can comprise the raised lip 64 and the groove, such that the raised lip 64 can be engaged with the groove 40 and the groove can be engaged with the raised lip on the first member 18 when the first member 18 is engaged with or positioned adjacent to the second member 20. In other various embodiments, a sealing member or material can be positioned intermediate the first member 18 and the second member 20, for example.
In one embodiment, referring to FIGS. 2, 3, 7, 8, 10, and 11, for example, the second member 20 can comprise apertures 48. Suitable fasteners can be passed through the apertures 48 to engage the second member 20 with the side wall 11 of the reservoir 12.
In one embodiment, at least one projection 66 can extend outwardly from the first side 60 of the second member 20. The at least one projection 66 can form a receiving portion 68 intermediate a portion of the at least one projection 66 and a portion of the first side 60. When the first member 18 is engaged with the second member 20, the first member 18 can be at least partially guided by the at least one projection 66 during insertion of the first member 18 onto the second member 20 and can be at least partially positioned within the receiving portion 68 when engaged with the second member 20 to form a connection or an engagement between the first member 18 and the second member 20. In one embodiment, portions of the outer edge 42 of the first member 18 can be at least partially engaged with the receiving portion 68 when the first member 18 is engaged with the second member 20.
In one embodiment, the at least one projection 66 can comprise a first projection, a second projection, and a third projection. The second member 20 can comprise a top edge 70 and a bottom edge 72. The first projection and the second projection can be positioned proximate to the top edge 70, and the third projection can be positioned proximate to the bottom edge 72, or proximate to a midpoint of the bottom edge 72. In one embodiment, the number of projections on the second member 20 can vary, as will be recognized by those of skill in the art. For example, four or more projections can be used. In an embodiment where only one projection is used, that projection can comprise an arcuately-shaped receiving portion, a truncated oval-shaped receiving portion, a 1⁄2 square or rectangular-shaped receiving portion, a truncated trapezoid-shaped receiving portion, a semi-circular-shaped receiving portion, and/or a triangular-shaped receiving portion, for example. Those of ordinary skill in the art will recognize that the perimetrical shape of the first member 18 can drive the shape of the receiving portion of the projection. For example, if the first member comprises a U-shaped perimeter, the second member can comprise a U-shaped receiving portion, such that the first member can be engaged with the second member.
In one embodiment, referring to FIGS. 16-21, another connector assembly 116 for a vortex valve is illustrated. The connector assembly 116 can be similar to the connector assembly 16 described above (like numerals will described like elements), but, in this embodiment, a first member 118 can comprise tapered or angled portions 144 and at least one projection 166 can comprise tapered or angled portions 145 to facilitate engagement of the first member 118 with a second member 120. In one embodiment, the first member 118 can comprise a triangular-shaped perimeter, for example. In various embodiments, a tapered or angled portion 144 can be positioned proximate to each corner of the triangular-shaped first member 118. The tapered or angled portion or portions 144 can be sized and configured to engage the tapered or angled portion or portions 145. The first member 118 can comprise a top edge 121 and a point 123. Tapered or angled portions 144 on the first member 118 can be positioned proximate to each corner of the first portion 118 near the top edge 121 and another tapered or angled portion 144 can be positioned proximate to the point 123. In one embodiment, the second member 120 can comprise a first projection 166, a second projection 166, and a third projection 166. Each of the projections 166 can comprise a receiving portion 168. Each receiving portion 168 can comprise the tapered or angled portion 145. The tapered or angled portions 145 of the second member 120 can be configured to mate with the tapered or angled portions 144 of the first member 118, such that the first member 118 can be essentially wedge-fit or press-fit into the projections 166 of the second member 120 while restricting over insertion of the first member 118. Although a triangular first member 118 and projections 166 on the second member 120 for receiving the same are illustrated, those of skill in the art will recognize that the first member can comprise a different shape and that the projections on the second member can be configured and arranged to receive such a differently shaped first portion.
In various embodiments, still referring to FIGS. 16-21, the tapered or angled portions 144 of the first member 118 and the tapered or angled portions 145 of the second member 120 can each comprise a feature that allows the first member 118 to essentially be removably locked into engagement with the second member 120 when the first member 118 is fully or at least mostly engaged or slidably engaged with the second member 120. Such a feature can also indicate to the installer of the first portion 118 that the first member 118 is fully and/or appropriately engaged with the second member 120. In various embodiments, the first member 118 can be snap-fit with the second member 120 and a “clicking” sound can be heard by the installer when the first member 118 is fully engaged with the second member 120. In one embodiment, one or more of the tapered or angled portions 144 can comprise a recess, for example, and one or more of the tapered or angled portions 145 can comprise a lip. The lip can at least partially engage the recess to removably interlock the first member 118 and the second member 120. In other various embodiments, one or more of the tapered or angled portions 144 can comprise a lip and one or more of the tapered or angled portions 145 can comprise the recess, for example, to accomplish a similar form of engagement between the first portion 118 and the second portion 120. Other suitable methods of removably interlocking the first member 118 and the second member 120 are within the scope of the present disclosure. If the recess and lip described above are provided, a user of the connector assembly 116 can slightly pull apart the first member 118 and the second member 120 to “unlock” the lip from the recess so that the first member 118 and the vortex valve can be removed from the second member 120 for maintenance, for example.
In one embodiment, referring to FIGS. 22 and 23, a gasket 124 is illustrated. In various embodiments, the gasket 124 or another suitable gasket can be used with the connector assembly 16 and/or the connector assembly 116. In one embodiment, the gasket 124 can comprise any suitable sealing member or material, such as a neoprene material, for example. The gasket 124 can be used to create a fluid-tight, or substantially fluid-tight, seal between the second side 162 of the second member 120 and the side wall 11 of the reservoir 12. In one embodiment, the gasket 124 can be positioned around the bore 132, or partially around the bore 132. In other embodiments, the gasket 124 can be positioned around, or partially around, a perimeter of the second side 162 of the second member 120. The gasket 124 can be attached to the second side 162 of the second member 120 using any suitable technique, such as gluing, for example. In other embodiments, the second side 162 can comprise a recess or groove configured to receive the gasket 124.
In one embodiment, referring to FIGS. 24-29, the vortex valve 10 can comprise a first portion 76 and a second portion 78. The first portion 76 can be configured to be attached to the first member 18 using the connection members 52. The first portion 76 can comprise the apertures 80 configured to receive the connection members 52. The first portion 76 can also define the outlet 28 of the vortex valve 10. In one embodiment, the apertures 80 can be positioned around, about, and/or proximate to the outlet 28 such that the annular flange 38 can be placed into fluid communication with the outlet 28 when the first member 18 is engaged with the first portion 76. In various embodiments, the first portion 76 can comprise fins 82 extending therefrom which can form the apertures 80, for example. In one embodiment, the first portion 76 can comprise a handle 84 or grip configured to be used to raise and lower the vortex valve 10 and the first member 18 attached thereon into a position of engagement with the second member 20 within a reservoir, a drainage gully, or other suitable location. In one embodiment, the handle 84 can be positioned on the first member 18 instead of on the first portion 76. The first portion 76 can comprise a dome-shaped portion 86 and an elongate portion 88.
In one embodiment, referring to FIGS. 26 and 27, the second portion 78 can comprise a dome-shaped portion 90 and an elongate portion 92. The dome-shaped portion 90 and the elongate portion 92 can be configured to be engaged with or attached to the dome shaped-portion 86 and the elongate portion 88, respectively, to form the vortex valve 10. In various embodiments, the first portion 76 can be connected to the second portion 78 using any suitable methods, such as snap-fitting, press-fitting, interlocking, gluing, and/or welding, for example. In one embodiment, when the first portion 76 is assembled to the second portion 78, the elongate portions 88 and 92 can define the inlet 26 of the vortex valve 10, while the dome-shaped portions 86 and 90 can define a vortex chamber of the vortex valve 10. In other various embodiments, the vortex valve 10 can be formed of one piece, though injection molding or other suitable process, for example.
In one embodiment, referring to FIGS. 24-29, and more specifically to FIGS. 28 and 29, the first portion 76 can comprise an edge comprising a first lip 94, a notch 96, a second lip 98, and a flange 100 defining a recess 101. The second portion 78 can comprise and edge comprising a notch 102, a lip 104, a recess 106, and an engagement member 108 defined on a flange 110. When the first portion 76 is engaged with the second portion 78, the above-mentioned features can be engaged as illustrated in FIGS. 28 and 29 to form a fluid-tight seal, or substantially a fluid-tight seal.
In one embodiment, referring to FIGS. 1 and 4, during installation of the connector assembly 16 or 116, the second member 20 can receive the end portion of the outlet conduit 14. The first member 18 can be engaged with the vortex valve 10 using the connection members 52 and the apertures 46 and 80, as described above. Once the first member 18 is engaged with the vortex valve 10, the vortex valve 10 and the first member 18 (as an assembly) can be lowered, positioned, moved, and/or slide into engagement with the second member 20, as described herein. When the first member 18 is engaged with the second member 20, the outlet 28 of the vortex valve 10, the bore 30 of the first member 18, the bore 32 of the second member 20, and the inlet opening of the outlet conduit 14 can be in fluid communication such that the fluid can flow from the reservoir 12 to the outlet conduit 14. In one embodiment, the first member 18 can be removably engaged with the second member 20 such that the vortex valve 10 and the first member 18 can be removed from the reservoir 12, drainage gully, and/or other structure for periodic maintenance, replacement, and/or monitoring of the vortex valve 10, for example.
In one embodiment, the first member 18 or 118 and the second member 20 or 120 can be comprised of a thermoplastic material, such as PVC, a thermoset material, and/or a metal material, for example.
In one embodiment, referring to FIGS. 30-37, a connector assembly 216 for a fluid flow restricting apparatus, such as vortex valve 210, for example, can comprise a first member 218, a second member 220, a seal 221, a sealing means, and an insert 225.
