DETAILED DESCRIPTION
Aspects of the present disclosure relate to modular sleeve valves, more particular aspects relate to configurable routing using in-floor configurable modular sleeve valves. While the present disclosure is not necessarily limited to such applications, various aspects of the disclosure may be appreciated through a discussion of various examples using this context.
While the same nomenclature and same numbers may be used to identify elements throughout the disclosure, this practice is not intended to limit the scope of the disclosure. Identified elements in one figure may not be identical to other same named or identified elements in other figures.
Embodiments of the present disclosure are directed to a modular sleeve valve apparatus. The modular sleeve valve can include a valve body having a first port on a first sidewall of the valve body and a second port on a second sidewall of the valve body. The valve can include a first valve core sleeved within the valve body. The first valve core can be a cylinder including a first aperture in a cylindrical sidewall of the first valve core and a second aperture in a top base-wall of the first valve core. The cylindrical sidewall can define a first space within the first valve core and the first valve core can be removable from the valve body and radially rotatable within the valve body.
The valve can include a second valve core sleeved within the valve body. The second valve core can be a cylinder including a third aperture in a cylindrical sidewall of the second valve core and a fourth aperture in a bottom base-wall of the second valve core. The cylindrical sidewall of the second valve core can define a second space within the second valve core. The second valve core can be removable from the valve body and radially rotatable within the valve body. The second valve core can be positioned stacked upon the first valve core to align the second aperture and the fourth aperture to create a combined space from the first and second spaces.
Valves can be used to create a plumbing system where a plurality of valves are interconnected with a plurality of pipes to route fluid from a source to one or more outputs. For example, a plurality of computers in a defined area, such as servers in a server room, could utilize a liquid cooling system where one or more of the servers require cooling liquid to draw heat away from the servers.
A plumbing system in the server room could be designed to route cooling liquid from a source to the servers in the server room. However, in some instances, it can be difficult to reconfigure the plumbing system after being initially designed and installed. For example, the plumbing system could be designed to provide cooling liquid to a plurality of predetermined positions in the server room from a predetermined source. If at some point the servers are repositioned in the room, the plumbing system may not be able to provide liquid to new positions of the servers.
Embodiments of the present disclosure are directed to a system of configurable liquid plumbing. The system can include a planar surface including a first junction-hole, a second junction-hole, and a first trench in the planar surface connecting the first junction hole to the second junction hole. In embodiments, the system can be constructed within a planar surface to create an in-floor plumbing system. In embodiments, the planar surface can be a concrete floor, or other type of floor. The junction holes can be indents in the planar surface where valves can be placed. The trenches are indents in the planar surface where piping can be placed to connect valves in the junction holes. For example, the system could include a first configurable valve in a first junction hole and a second configurable valve in the second junction hole. The system could include and a trench connecting the first and second junction holes and a pipe in the trench connecting the first and second valves. In embodiments, the configurable valves can be a modular valve where modular components can be inserted and/or removed from the valve to configure the valves depending upon the requirements of the system.
Embodiments of the present disclosure are directed toward a modular sleeve valve. In embodiments, a modular sleeve valve can include a valve body including at least two ports on the valve body. In embodiments, the valve body is the outer casing of the modular sleeve valve that contains the components of the modular sleeve valve. For example, described further herein, the valve body can contain one or more valve cores which are configured to direct the flow of fluid through the modular sleeve valve. The valve body can be constructed as various shapes and sizes. For example, the valve body could be constructed as a cylinder. Ports could be positioned on a cylindrical sidewall of the valve body. In certain examples, the valve body could be constructed as a geometric prism, such as a cuboid or other prism. A first port could be positioned on a first sidewall of the valve body and a second port could be positioned on a second sidewall of the valve body. In embodiments, the ports are passages that allow fluid to pass through the valve body. For example, the first port could be used to intake fluid into the modular sleeve valve and the second port could be used to exhaust fluid from the modular sleeve valve.
In embodiments, the modular sleeve valve includes a valve core. In embodiments, a valve core is a movable obstruction inside the valve body that adjustably restricts flow of fluid through the modular sleeve valve. In embodiments, described further herein, the position of the valve core in the valve body can configure the direction of the fluid flow in the modular sleeve valve. For example, the valve core could be movable between a first position and a second position. In the first position, fluid could enter the modular sleeve valve at a first port and exit the modular sleeve valve at a second port. In the second position, passage through the modular sleeve valve could be blocked so that the modular sleeve valve is closed.
In embodiments, the valve cores are modular and can be removed and/or added to the valve body. For example, a first valve core could be removed from the valve body and replaced with a second and third valve core positioned in the valve body. Described further herein, the valve cores can be constructed as various designs so that the function, routing capabilities and other features of the modular sleeve valve can be configured by a user.
Referring now to FIG. 1, an exploded view of a modular sleeve valve 100 can be seen according to embodiments of the present disclosure. The modular sleeve valve 100 can include a valve body 102 having a plurality of ports 104A-104D including a first port 104A, a second port 104B, a third port 104C, and a fourth port 104D. The modular sleeve valve 100 can include a first valve core 112 having a first aperture 114 and a second aperture 116, and a second valve core 122 having a third aperture 124 and fourth aperture 126.
The valve body 102 can be the exterior structure of the modular sleeve valve 102. The valve body can contain the various components of the modular sleeve valve 100. For example, the valve body can contain one or more valve cores described further herein.
The valve body 102 can include ports 104A-104D. The ports 104A-104D can provide access for fluid to enter and/or exit the modular sleeve valve 100. For example, each port 104A-104D can serve as an intake port where fluid enters the modular sleeve valve, or as an exhaust port were fluid exits the modular sleeve valve. In embodiments, the valve body 102 can include at least two ports 104A-104D. For example, in FIG. 1, the valve body 102 can include a first port 104A, a second port 104B, a third port 104C, and a fourth part 104D. For example, the first port 104A could intake fluid into the modular sleeve valve 100. Described further herein, the modular sleeve valve 100 could be configured to exhaust the fluid to the third port 104C. In certain embodiments, any of the ports could be used as intakes or exhausts depending upon the configuration of the modular sleeve valve 100.
The ports 104A-104D can be positioned on one or more sidewalls of the valve body 102. For example, where the valve body 102 is a cuboid having at least four sidewalls, each of the ports 104A-104D could be positioned on a sidewall. Thus, the first port 104A could be positioned on a first sidewall, the second port 104B could be positioned on a second sidewall, the third port 104C could be positioned on a third sidewall, and the fourth port 104D could be positioned on a fourth sidewall. In embodiments, the valve body 102 can be a cylinder having a cylindrical sidewall, as seen in FIG. 1. The ports 104A-104D can be positioned on the cylindrical sidewall of the valve body 102.
Each of the ports 104A-104D can include exterior openings 106A-106D and interior openings 108A-108D. The exterior openings 106A-106D can be positioned on the sidewall of the valve body 102. The interior openings can be positioned within the valve body, adjacent to the first and second valve cores. In embodiments, the interior openings 108A-108D are widened, relative to the exterior opening 106A-106D. For example, the interior opening 108A-108D could be widened to be at least twice as large as the exterior opening 106A-106D. In embodiments, the interior openings 108A-108D can be widened to align with the first aperture 114 and the third aperture 124 of the first and second valve cores 112, 122 such that liquid entering/exiting the modular sleeve valve 100 can be directed to the first and third apertures 114, 124.
The valve body 102 can include a cap base-wall 110. The cap base-wall 110 can be a removable portion of the valve 102 which allows components to be changed within the modular sleeve valve 100. For example, described further herein, the first and second valve cores 112, 122 can be removable from the valve body and replaced with other types of valve cores. In embodiments, the cap base-wall 110 can secure the first and second valve cores 112, 122 in the valve body 102 when attached to the valve body 102. Thus, when the cap base-wall 110 is removed, the first and second valve cores 112, 122 can be removed from the valve body. In embodiments, the cap base-wall 110 can be secured to the valve body 102 via clamps, screws, latches, or other suitable types of fasteners.
The first and second valve cores 112, 122 are valve cores which can be configured to direct the flow of fluid within the modular sleeve valve 100. The first and second valve cores can be cylinders which are inserted and sleeved within the valve body 102.
The first valve core 112 can include a first aperture 114 in a cylindrical sidewall of the first valve core 112 and a second aperture 116 in a top base-wall of the first valve core. The cylindrical sidewall can define a first space 125 within the first valve core 112.
The second valve core 122 can include a third aperture 124 in a cylindrical sidewall of the second valve core 122 and a fourth aperture 126 in a bottom base-wall of the second valve core 122. The cylindrical sidewall of the second valve core 122 can define a second space 127 within the second valve core 122. The second valve core 122 can be positioned stacked upon the first valve core 112 to align the second aperture 116 and the fourth aperture 126 to create a combined space from the first and second spaces. Described further herein, fluid can be directed within the modular sleeve valve by the first and second valve cores 112, 122 by flowing through the first aperture 114, the combined space, and third aperture 124.
In embodiments, the first and second valve cores 112, 122 are independently radially rotatable within the valve body 102. For example, the first and second valve cores 112, 122 could be independently radially rotatable between a first position, a second position, a third position, and a fourth position.
In embodiments, when the first valve core 112 is in the first position the first aperture 114 is aligned with the first port 104A. In embodiments, when the second valve core 122 is in the first position, the third aperture 124 is aligned with the first port 104A. In embodiments, when the first valve core 112 is in the second position, the first aperture is aligned with the second port 104B. In embodiments, when the second valve core 122 is in the second position, the third aperture 124 is aligned with the second port 104B. In embodiments, when the first valve core 112 is in the third position, the first aperture 114 is aligned with the third port 104C. In embodiments, when the second valve core 122 is in the third position, the third aperture 124 is aligned with the third port 104C. In embodiments, when the first valve core 112 is in the fourth position, the first aperture 114 is aligned with the fourth port 104D. In embodiments, when the second valve core 122 is in the fourth position, the third aperture 124 is aligned with the fourth port 104D.

When the first and second valve cores 112, 122 are aligned with a port 104A-104D, the combined space can be accessed through the aligned ports and through the first and third apertures 114, 124. For example, when the first valve core 112 is in the second position, the first aperture 114 can be aligned with the second port 104B allowing access from the second port 104B to the combined space. When the second valve core 122 is in the third position, the third aperture 124 can be aligned with the third port 104C, allowing access from the third port 104C to the combined space. Thus, liquid could flow through the modular sleeve valve 100 by entering the third port 104C entering the combined space, and exiting through the second port 104B.
In embodiments, the first valve core 112 includes a first handle 120 and a stem 118. The stem 118 has a first end connected to a bottom base-wall of the first valve core 112 and a second end extended through the combined space to at least a top base-wall of the second valve core 122. The first handle 120 can be connected to the second end.

The third aperture 124 and the fourth aperture 126 allow access to the second space 204 within the second valve core 122.
In embodiments, the first valve core 112 and the second valve core 122 could include a plurality of apertures in the cylindrical sidewalls. For example, the first valve core 112 could include at least two apertures in the cylindrical sidewall so that fluid could enter or exit the modular sleeve valve through two or more ports 104A-104D (FIG. 1).
In embodiments, the first and second valve cores 112, 122 are stacked together in a valve body 102 (FIG. 1), as described herein. The second valve core 122 can be stacked upon the first valve core such that the second aperture 116 and the fourth aperture 126 are aligned. When the first and second valve cores are stacked, a combined space can be formed from the first space and the second space through the second and fourth apertures 116, 126. In embodiments, the first and second valve cores 112, 122 can include a gasket and/or spacer to seal the alignment of the second aperture 116 and the fourth aperture 126. The gasket and/or spacer can reduce leakage of liquid between the first and second valve cores 112, 122 and improve flow of liquid through the modular sleeve valve 100 (FIG. 1).
The first valve core 112 includes a first handle 120 and a stem 118. The stem 118 has a first end connected to a bottom base-wall of the first valve core 112 and a second end extended through the combined space of the first and second spaces 202, 204 to at least a top base-wall of the second valve core 122.

Referring now to FIG. 7, a top view of a system 700 of configurable liquid plumbing can be seen according to embodiments of the present disclosure. The system 700 can include a planar surface 701 including a plurality of junction holes 714 and trenches 710. The planar surface 701 can be the same or substantially similar as described herein.
The system 700 can include a first row 702 of a plurality of junction holes 708. The junction holes 708 can be the same or substantially similar as described herein. Each of the junction holes 708 in the first row 702 can be separated from one another by a row distance 714. The row distance 714 can be selected as various distances depending upon the requirements of the system 700 and the preferences of a user. In embodiments, the row distance is selected as six hundred millimeters. Similarly, in embodiments, each of the junction holes 708 in the second row 704 and each of the junction holes 708 in the third row 706 can be separated from one another by the row distance 714. A plurality of trenches 710 can connect each of the junction holes 708 in the first, second, and third rows 702, 704, and 706.
Each of the rows can be separated from adjacent rows by a column distance 716. For example the first row 702 and second row 704 can be separated by the column distance 716, and the second row 704 and the third row 706 can be separated by the column distance 716. The row distance 714 can be selected as various distances depending upon the requirements of the system 700 and the preferences of a user. In embodiments, the row distance 714 is selected as six hundred millimeters. A plurality of trenches 710 can connect each of the junction holes 708 in the first, second, and third rows 702, 704, 706. Thus, the system 700 can have a plurality of junction holes 708 and a plurality of trenches 710 which form a grid pattern as seen in FIG. 6.
