BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a turbine inspection stopper.

Description of the Prior Art

Generally, to measure an air pressure in a flexible tub of a turbine, or to inspect whether there are leaks, a stopper is needed to be arranged on openings of two ends of the turbine to make an interior of the turbine be a closed space. Then, the turbine is inspected through vacuumizing the interior of the turbine or guiding air into the interior of the turbine.

However, in the prior art, the stopper is often used to plug the openings of the turbine, so the industry does not further design or improve a structure of the stopper. The traditional stoppers are mostly solid tube plugs which are material-wasting and heavy, and it is hard for a user to move the stoppers around. In addition, the stoppers are unable to vary flexibly due to the solid structures, and when the stoppers are engaged with the turbine, there may be unexpected abrasion.

SUMMARY OF THE INVENTION

The major object of the present invention is to provide a turbine inspection stopper, which can effectively reduce a weight of a stopper so that a user can assemble or disassemble the stopper more smoothly and can prevent the stopper from abrading with a turbine so as to prolong a service life of the stopper and the turbine.

To achieve the above and other objects, a turbine inspection stopper is provided, including a main body and a pressure gauge. The main body has a base portion, an annular flange which is laterally disposed around the base portion and an air passage, the annular flange is for being connected to one of two ends of a turbine, the base portion and the annular flange define an interior space, the interior space is for communicating with an interior of the turbine, and the air passage is for communicating with outside and the interior of the turbine; and at least one part of the pressure gauge is buried in the main body and communicates with the interior space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer toFIGS. 1 to 6for a preferred embodiment of the present invention. A turbine inspection stopper includes a main body1and a pressure gauge7.

The main body1has a base portion2, an annular flange3which is laterally disposed around the base portion2and an air passage4, the annular flange3is for being connected to one of two ends of a turbine B, the base portion2and the annular flange3define an interior space5, the interior space5is for communicating with an interior of the turbine B, the air passage4is for communicating with outside and the interior of the turbine B; and at least one part of the pressure gauge7is buried in the main body1and communicates with the interior space5. Through a structure of the interior space5, an overall weight of the turbine inspection stopper can be reduced, and it is more convenient for a user to take and operate the turbine inspection stopper. In addition, the interior space5provides a margin for deformation so that when the annular flange3is engaged with the turbine B can slightly deform to prevent the annular flange3and the turbine B from being damaged due to ramming.

More specifically, the main body1defines a central axis A and further has an axle portion6and at least one connecting rib61, the axle portion6is located in the interior space5and connected to the base portion2, each said connecting rib61is connected to the axle portion6and the annular flange3and lateral to the central axis A, and each said connecting rib61can strengthen a whole structure to resist greater impact. In this embodiment, the main body1has a plurality of said connecting ribs61, two of said connecting ribs61, a part of the annular flange3and a part of the axle portion6define a block63(as shown inFIG. 4), each said block63has a strengthening portion64, and each said strengthening portion64is connected to at least one of said connecting ribs61and the base portion2to enhance a structural stability. Preferably, the connecting ribs61are equidistantly arranged in the receiving space5to evenly distribute weight, a place of each said connecting rib61which is near the annular flange3and a place of each said connecting rib61which is near the axle portion6respectively have a reinforcing rib62; and likewise, the reinforcing rib62is used to elevate a strength of the connecting rib61.

More specifically, the base portion2further has a receiving portion22, the pressure gauge7is preferably entirely buried within the receiving portion22, the receiving portion22can block unexpected objects from impacting the pressure gauge7directly so as to protect the pressure gauge7from being impacted and damaged and to provide preferable operation environment and service life. In this embodiment, a part of the pressure gauge7is disposed through the base portion2and fixedly engaged with a hexagonal nut71; in other words, the pressure gauge7is detachable, so when a component is damaged, only the damaged part, instead of the whole structure, needs to be replaced. In addition, as viewed along the central axis A, the axle portion6is O-shaped, and the receiving portion22is O-shaped.

It is to be noted that the base portion2further has at least one protrusive rib23, and each said protrusive rib23is connected to an exterior annular wall of the receiving portion22and lateral to the central axis A so that the user can clamp or grip on the at least one protrusive rib23to drive the main body1to move or rotate. Preferably, the main body1is integrally formed and has a preferable structural strength. In this embodiment, the base portion2has four of said protrusive ribs23, and the protrusive ribs23extend to be substantially cruciform, each said protrusive rib23corresponds to one of the connecting ribs61, and the receiving portion22is located at an intersection of the four protrusive ribs23(as shown inFIG. 1). In addition, the base portion2further has a bottom portion21which is round, the receiving portion22and the protrusive ribs23are connected to one of two sides of the bottom portion21, the annular flange3is connected to the other of the two sides of the bottom portion21.

The annular flange3is substantially cylindrical and coaxially arranged with the main body1, and the bottom portion21is greater than the annular flange3in radial dimension. Preferably, the annular flange3has a first diameter section31and a second diameter section32, and the first diameter section31is connected to the base portion2and the second diameter section32. The first diameter section31is greater than the second diameter section32in outer diameter, inner diameters of the first and second diameter sections31,32are in the same dimension, and through the different radial dimensions, the annular flange3can be adapted to the turbine B which has two different tube diameters. Of course, in other embodiments, the annular flange may be provided with more diameter sections in various dimensions so as to be adapted to more different tube diameters. preferably, a side of the first diameter section31which is away from the base portion2has a first margin311, a side of the second diameter section32which is away from the base portion2has a second margin322, and the first and second margins311,322are for optionally abutting against an inner wall of the turbine B. The first and second margins311,322can reinforce the engagement with the turbine B so that the main body1can be preferably and stably engaged with the turbine B and will not be disassembled from the turbine B due to shaking.

To be more specific about the air passage4, the air passage4has a first flow channel41and a second flow channel42which communicates with the first flow channel41, a tool adapter72is assembled to the first flow channel41for a gaseous fluid to pass therethrough, and the second flow channel42is for communicating with the interior of the turbine B. Preferably, the tool adapter72is a check valve assembly so that the gaseous fluid can move unidirectionally to input and output the gaseous fluid genuinely.

Specifically, when being inspected, the turbine B inputs and outputs the gaseous fluid, so the tool adapter72is either an air input adapter or an air output adapter. Following descriptions are examples only and may be varied in accordance with different requirements in actual practice. For example, inFIGS. 1 to 4, the tool adapter72on the main body1is the air input adapter, and inFIG. 5, the tool adapter72of a main body1A in another mode is the air output adapter. Therefore, when being inspected, as shown inFIG. 6, one of the two ends of the turbine B is specifically used to exhaust the gaseous fluid in the interior of the turbine B, the other end of the two ends of the turbine B is specifically used to pump the gaseous fluid into the interior of the turbine B, so it is clear to understand how to operate and arrange the tool adapters72,72A onto the turbine B. It is understandable that in accordance with different requirements, in other embodiments, the main body may be provided with two types of tool adapters so that the main body can input and output the gaseous fluid.

More specifically, in this embodiment, the first flow channel41is perpendicular to the central axis A and penetrates one of said protrusive ribs23, and the second flow channel42is parallel to the central axis A and disposed through one of said connecting ribs61and the base portion2; the first and second flow channels41,42form an L shape; and the first flow channel41is greater than the second flow channel42in radial dimension. The tool adapter72is screwed with the first flow channel41for being assembled or disassembled conveniently. In addition, when manufacturing the second flow channel42, a drill bit drills along the central axis A and through the main body1, and a through hole which communicates with outside is plugged by a barrier73(as shown inFIG. 3).

Given the above, a weight of the turbine inspection stopper can be effectively reduced, and with the at least one protrusive rib, it is easy for the user to grip on and operate the turbine inspection stopper. Furthermore, the connecting rib is further provided to strengthen the whole structure to sustain greater impact.

In addition, through the pressure gauge which is buried in the main body, the user can see the pressure gauge to know a pressure in the interior of the turbine. Since the pressure gauge is buried in the main body, the pressure gauge can be prevented from receiving unexpected impact and being damaged so as to have preferable operation environment and service life.

Furthermore, the annular flange has different diameter sections to be adapted to the turbines having different tube diameter sections, so the user does not need to purchase too many turbine inspection stoppers. There are margins on different tube diameter sections to enhance the engagement and stability of the annular flange and the turbine.
