Description

Technical Field

[0001] This utility model belongs to the field of valve thrust testing technology, and in particular relates to a valve thrust testing device. Background Technology

[0002] A valve thrust tester is a device used to measure the thrust a valve experiences during operation. It applies thrust to the valve through a loading system, gradually increasing the thrust until a set test value is reached or the valve is damaged, thereby testing the valve's thrust. It is generally used for quality inspection of valves in production to ensure that the valve's performance meets standard requirements.

[0003] For example, Chinese patent CN220960590U discloses a valve testing device, including a housing. An adjustment mechanism is installed on the housing wall. The adjustment mechanism consists of a fixed frame, an electric telescopic rod, a limit rod, a fixed plate, a pump body, an adjustment plate, a crossbar, and a flange A. A fixed frame is welded to the housing wall, and an electric telescopic rod is bolted to the frame wall. A crossbar is installed at the output end of the electric telescopic rod, and the other end of the crossbar is welded to the wall of the adjustment plate. A set of symmetrical limit rods is welded to the inner wall of the housing, and the limit rods penetrate the adjustment plate. After an external water source is connected to the pump body, the output end of the pump body is connected to one end of the flange A via a conduit. This allows the external water source to enter the flange A through the conduit, thus allowing water to enter the valve and test its seal.

[0004] The aforementioned patent has the following problems:

[0005] This patent has some drawbacks in its use. For example, when testing valves, the device can only perform fixed tests on valves of a single size. However, common valve sizes come in many varieties. When testing valves of different sizes, personnel need to replace the entire device, which is cumbersome and consumes a lot of manpower and time. In view of this, we propose a valve thrust testing device. Utility Model Content

[0006] The purpose of this invention is to provide a valve thrust testing device to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a valve thrust testing device, comprising:

[0008] The test chamber has a sliding groove at the bottom of its inner cavity, a sliding plate slidably installed in the sliding groove, and sliding grooves on both the inner wall of the test chamber and one side of the sliding plate. A movable plate is slidably installed in each of the two sliding grooves, and several installation tubes are fixedly installed on the opposite side of the two movable plates. A sealing gasket is fixedly installed on the side of the two movable plates that are far apart from each other.

[0009] A drive assembly, located within a sliding groove, is used to drive the sliding plate to move.

[0010] A limiting component is located on the test box and the sliding plate, and is used to limit the movement of the two moving plates;

[0011] A water outlet pipe is fixedly installed on the other side of the sliding plate. One end of the water outlet pipe is connected to one of the mounting pipes on the sliding plate. A water pump is fixedly installed on one side of the test box. A connecting pipe is fixedly installed at the outlet of the water pump. A water pressure gauge is fixedly installed on the connecting pipe. One end of the connecting pipe is connected to one of the mounting pipes on the test box.

[0012] In this technical solution, during use, personnel can first test the valve size as needed. First, the limiting component releases the two moving plates, allowing the personnel to move the moving plates, causing them to slide within the groove. Simultaneously, the moving plates move several mounting tubes on them until a mounting tube of the appropriate size moves to the center of the test chamber. Then, the limiting component again limits the two moving plates. Next, the personnel can place the pipe with the valve installed into the test chamber, positioning it between the two moving plates. The driving component then moves the sliding plate, causing several mounting tubes on it to move until two corresponding mounting tubes clamp the pipe. Finally, the personnel can fix the pipe between the two mounting tubes using the pipe and the flanges on the two mounting tubes, ensuring that valves of different sizes can be tested, thus improving the overall compatibility of the device.

[0013] Then, the personnel can start the water pump, which can deliver water to the connecting pipe. The water in the connecting pipe will then enter the test pipe through one of the installation pipes on the test box and impact the valve. At the same time, the personnel can observe the water pressure inside the connecting pipe through the water pressure gauge until the valve shows signs of leakage. At this point, the thrust of the valve can be tested.

[0014] In the above technical solution, the driving component further includes:

[0015] A threaded rod is rotatably installed in a sliding groove. One end of the threaded rod passes through the sliding plate and one side of the sliding groove and extends to the outside. A knob is fixedly installed at one end of the threaded rod on the other side of the test box.

[0016] In this technical solution, a valve-equipped pipeline can be placed inside the test chamber, positioning the pipeline between two movable plates. Turning a knob causes a threaded rod to rotate, which in turn moves a sliding plate. This movement of the sliding plate then moves several mounting tubes on it until two corresponding mounting tubes clamp the pipeline. Personnel can then secure the pipeline between the two mounting tubes using the pipeline and the flanges on the two mounting tubes, ensuring that valves of different sizes can be tested, thus improving the overall compatibility of the device.

[0017] In the above technical solution, the threaded rod is further threadedly connected to the sliding plate.

[0018] In this technical solution, it is ensured that the rotation of the threaded rod can drive the sliding plate to move.

[0019] In the above technical solution, the limiting component further includes:

[0020] Two limiting grooves are respectively opened in the sliding plate and the test box, and the two limiting grooves are respectively located above the two moving plates. The top of the moving plate has several limiting holes. A limiting block is slidably installed in the limiting groove. The bottom end of the limiting block passes through the bottom of the limiting groove and extends into one of the limiting holes. A pull rod is fixedly installed at the top of the limiting block and located in the limiting groove. The top end of the pull rod passes through the top of the limiting groove and extends to the outside. A spring is sleeved on the pull rod and located in the limiting groove.

[0021] In this technical solution, during use, personnel can first test the valve size as needed, and then pull up the two levers respectively. The upward movement of the levers will cause the limit block to move upward, and the upward movement of the limit block will compress the spring and retract it until the bottom end of the limit block moves out of one of the limit holes. At this time, the limit block can release the limiting of the moving plate. Then, the personnel can move the moving plate so that it slides in the slide groove. At the same time, the moving plate will drive several mounting tubes on the moving plate to move until the mounting tube of the appropriate size moves to the center of the test box and stops. Then, the levers are released. At this time, under the action of the spring rebound force, the spring will compress the limit block to move downward until the bottom end of the limit block is inserted into the corresponding limit hole. The limit block can limit the moving plate.

[0022] In the above technical solution, the bottom end of the limiting block is inserted into the limiting hole, the pull rod is slidably connected to the limiting groove, and the two ends of the spring are respectively tightly welded to the inner wall of the limiting block and the limiting groove.

[0023] In this technical solution, it is ensured that the bottom end of the limiting block can be inserted into the limiting hole, that the pull rod can slide normally in the limiting groove, and that the spring structure is stable.

[0024] In the above technical solution, the sealing gasket is in close contact with the inner wall of the groove, and the cross-section of the moving plate is T-shaped.

[0025] In this technical solution, the sealing gasket ensures that the moving plate will not leak water and will not fall out of the groove.

[0026] Furthermore, in the above technical solution, the dimensions of some of the installation tubes are different.

[0027] In this technical solution, the structural stability of several installation pipes is ensured, guaranteeing the ability to test valves of different sizes, thereby improving the overall compatibility of the device.

[0028] The beneficial effects of this utility model are:

[0029] This valve thrust testing device, through the setting of a limiting component, and with the cooperation of the limiting component, driving component, two moving plates, several mounting pipes, sliding plate, water pump, connecting pipe, and water pressure gauge, ensures that valves of different sizes can be tested, thereby improving the overall compatibility of the device and also testing the magnitude of the valve thrust.

[0043] Please see Figure 1 - Figure 6 As shown, this embodiment provides a valve thrust testing device, including:

[0044] Test chamber 1, the bottom of the inner cavity of test chamber 1 is provided with a sliding groove 2, a sliding plate 3 is slidably installed in the sliding groove 2, the inner wall of test chamber 1 and one side of the sliding plate 3 are provided with a sliding groove 6, a movable plate 7 is slidably installed in both sliding grooves 6, several installation tubes 8 are fixedly installed on the opposite side of the two movable plates 7, and a sealing gasket 9 is fixedly installed on the side of the two movable plates 7 that are far apart from each other.

[0045] The drive component is located inside the sliding groove 2 and is used to drive the sliding plate 3 to move.

[0046] A limiting component is located on the test box 1 and the sliding plate 3, and is used to limit the movement of the two moving plates 7;

[0047] Water outlet pipe 10 is fixedly installed on the other side of sliding plate 3. One end of water outlet pipe 10 is connected to one of the mounting pipes 8 on sliding plate 3. Water pump 11 is fixedly installed on one side of test box 1. Connecting pipe 12 is fixedly installed at the outlet of water pump 11. Water pressure gauge 13 is fixedly installed on connecting pipe 12. One end of connecting pipe 12 is connected to one of the mounting pipes 8 on test box 1.

[0048] In operation, personnel can first test the valve size as needed. Using a limiting component, the two moving plates 7 are released from their limits. Then, the personnel can move the moving plates 7, allowing them to slide within the groove 6. Simultaneously, the moving plates 7 will move several mounting pipes 8 on them until a mounting pipe of the appropriate size moves to the center of the test chamber 1. The limiting component then limits the two moving plates 7 again. Next, the personnel can place the pipe with the valve installed into the test chamber 1, positioning it between the two moving plates 7. Using a driving component, the sliding plate 3 moves, causing several mounting pipes 8 on it to move until two corresponding mounting pipes 8 clamp the pipe. Finally, the personnel can fix the pipe between the two mounting pipes 8 using the pipe and the flanges on the two mounting pipes 8, ensuring that valves of different sizes can be tested, thus improving the overall compatibility of the device.

[0049] Then, the personnel can start the water pump 11, which can deliver water into the connecting pipe 12. The water in the connecting pipe 12 will then enter the test pipeline through one of the installation pipes 8 on the test box 1 and impact the valve. At the same time, the personnel can observe the water pressure inside the connecting pipe 12 through the water pressure gauge 13 until the valve leaks. At this time, the thrust of the valve can be tested. Example 2

[0050] This embodiment provides a valve thrust testing device, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a driving component comprising:

[0051] The threaded rod 4 is rotatably installed in the sliding groove 2. One end of the threaded rod 4 passes through the sliding plate 3 and one side of the sliding groove 2 and extends to the outside. A knob 5 is fixedly installed at one end of the threaded rod 4 and on the other side of the test box 1.

[0052] The valve-equipped pipe can be placed inside the test chamber 1, positioning the pipe between two movable plates 7. Then, the knob 5 is rotated, which in turn rotates the threaded rod 4. Under the action of the thread, the rotation of the threaded rod 4 moves the sliding plate 3, which in turn moves several mounting pipes 8 on the sliding plate 3 until two corresponding mounting pipes 8 clamp the pipe. Subsequently, personnel can fix the pipe between the two mounting pipes 8 through the pipe and the flanges on the two mounting pipes 8, ensuring that valves of different sizes can be tested, thereby improving the compatibility of the overall device. Example 3

[0053] This embodiment provides a valve thrust testing device, which, in addition to the technical solution of the above embodiment, also has the following technical features: the threaded rod 4 is threadedly connected to the sliding plate 3.

[0054] Specifically, it is ensured that the rotation of the threaded rod 4 can drive the sliding plate 3 to move. Example 4

[0055] This embodiment provides a valve thrust testing device, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a limiting component:

[0056] Two limiting grooves 14 are respectively opened in the sliding plate 3 and the test box 1, and the two limiting grooves 14 are respectively located above the two moving plates 7. The top of the moving plate 7 is provided with several limiting holes 16. A limiting block 15 is slidably installed in the limiting groove 14. The bottom end of the limiting block 15 passes through the bottom of the limiting groove 14 and extends into one of the limiting holes 16. A pull rod 17 is fixedly installed on the top of the limiting block 15 and located in the limiting groove 14. The top end of the pull rod 17 passes through the top of the limiting groove 14 and extends to the outside. A spring 18 is sleeved on the pull rod 17 and located in the limiting groove 14.

[0057] In operation, personnel can first test the valve size as needed by pulling up both levers 17. The upward movement of levers 17 will cause the limit block 15 to move upward, which in turn will compress the spring 18 until the bottom end of the limit block 15 moves out of one of the limit holes 16. At this point, the limit block 15 can release the limit on the moving plate 7. Then, personnel can move the moving plate 7 so that it slides in the slide groove 6. At the same time, the moving plate 7 will drive several mounting tubes 8 on the moving plate 7 to move until the mounting tube 8 of the appropriate size moves to the center of the test box 1 and stops. When the levers 17 are released, the spring 18 will press the limit block 15 downward under the action of the spring rebound force until the bottom end of the limit block 15 is inserted into the corresponding limit hole 16, and the limit block 15 can limit the moving plate 7. Example 5

[0058] This embodiment provides a valve thrust testing device, which, in addition to the technical solution of the above embodiment, also has the following technical features: the bottom end of the limiting block 15 is inserted into the limiting hole 16, the pull rod 17 is slidably connected to the limiting groove 14, and the two ends of the spring 18 are tightly welded to the inner walls of the limiting block 15 and the limiting groove 14, respectively.

[0059] Specifically, this ensures that the bottom end of the limiting block 15 can be inserted into the limiting hole 16, that the pull rod 17 can slide normally within the limiting groove 14, and that the structure of the spring 18 is stable. Example 6

[0060] This embodiment provides a valve thrust testing device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the sealing gasket 9 is in close contact with the inner wall of the slide groove 6, and the cross-section of the moving plate 7 is T-shaped.

[0061] Among these measures, the sealing gasket 9 ensures that the movable plate 7 will not leak water and will not fall out of the groove 6. Example 7

[0062] This embodiment provides a valve thrust testing device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: several mounting tubes 8 have different sizes.

[0063] In particular, ensuring the structural stability of several installation pipes 8 guarantees the ability to test valves of different sizes, thereby improving the overall compatibility of the device.

[0064] Working principle: In use, the operator can first test the size of the valve as needed by pulling up the two levers 17. The upward movement of the levers 17 will cause the limit block 15 to move upward. The upward movement of the limit block 15 will compress the spring 18 and retract it until the bottom end of the limit block 15 moves out of one of the limit holes 16. At this time, the limit block 15 can release the limit on the moving plate 7. Then the operator can move the moving plate 7 so that the moving plate 7 slides in the slide groove 6. At the same time, the moving plate 7 will drive several mounting tubes 8 on the moving plate 7 to move until the mounting tube 8 of the appropriate size moves to the center of the test box 1 and stops. When the levers 17 are released, under the action of the rebound force of the spring 18, the spring 18 will compress the limit block 15 and move it downward until the bottom end of the limit block 15 is inserted into the corresponding limit hole 16. The limit block 15 can limit the moving plate 7.

[0065] Subsequently, personnel can place the valve-equipped pipe into the test chamber 1, positioning the pipe between the two movable plates 7. Then, turn the knob 5. Turning the knob 5 will cause the threaded rod 4 to rotate. Under the action of the thread, the rotation of the threaded rod 4 will cause the sliding plate 3 to move. The movement of the sliding plate 3 will cause several mounting pipes 8 on the sliding plate 3 to move until two corresponding mounting pipes 8 clamp the pipe. Then, personnel can fix the pipe between the two mounting pipes 8 through the pipe and the flanges on the two mounting pipes 8, ensuring that valves of different sizes can be tested, thereby improving the compatibility of the overall device.

[0066] Then, the personnel can start the water pump 11, which can deliver water into the connecting pipe 12. The water in the connecting pipe 12 will then enter the test pipeline through one of the installation pipes 8 on the test box 1 and impact the valve. At the same time, the personnel can observe the water pressure inside the connecting pipe 12 through the water pressure gauge 13 until the valve leaks. At this time, the thrust of the valve can be tested.
