Description

Technical Field

[0001] This utility model relates to the field of sealing test fixture technology, and in particular to a sealing test fixture for a two-way shut-off valve. Background Technology

[0002] During the production of lithium batteries, a carbon-containing slurry is evenly coated on both sides of copper and aluminum foil to serve as the carrier for energy storage and discharge. The production, transportation, and final delivery of the slurry to the coating equipment require numerous valves for control. Leaks in these valves not only affect the quality of the final battery coating but also pose serious safety hazards to the factory.

[0003] In the prior art, there is no specific testing fixture for testing the sealing performance of two-way shut-off valves. Therefore, a sealing testing fixture for two-way shut-off valves is proposed here. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a sealing test fixture for a two-way shut-off valve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sealing test fixture for a two-way shut-off valve includes a base plate, a first mounting seat on the base plate, a horizontal moving device on the first mounting seat, a moving plate on the drive end of the horizontal moving device, a mounting seat fixedly mounted on the other side of the moving plate, and a sealing block on one side of the mounting seat.

[0007] A baffle is provided on the base plate, a sealing gasket is provided on one side of the baffle, and a second mounting seat is provided between the baffle and the horizontal moving device;

[0008] The base plate is provided with a first valve and a second valve. A first connecting pipe is provided on one side of the first valve, and the other side of the first connecting pipe is connected to the horizontal moving device.

[0009] An air inlet is provided on one side of the mounting base, and an air outlet is provided on one side of the sealing block. The air inlet and the air outlet are connected. A second connecting pipe is provided on one side of the second valve, and a pressure detection component is connected to the other side of the second connecting pipe. A third connecting pipe is provided on the other side of the pressure detection component, and the third connecting pipe is connected to the air inlet.

[0010] Preferably, the pressure detection component is a pressure gauge, and the horizontal movement device is a cylinder.

[0011] Preferably, the bottom of the base plate is provided with a plurality of feet, and the top of each of the plurality of feet is provided with a threaded rod, the threaded rod being threadedly connected to the bottom of the base plate.

[0012] Preferably, a handle is provided on both sides of the upper part of the base plate, and an opening is provided on both sides of the handle. A screw is provided on one side of the opening, and the screw passes through the opening and is spirally connected to the base plate.

[0013] Preferably, the sealing block and the sealing gasket are both made of silicone, and the base plate and the baffle are both made of aluminum.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes a second mounting base to place the product under test. An external air source is connected to one side of both the first and second valves. In use, opening the first valve moves the horizontal moving device, causing the sealing block and gasket to clamp the product under test. Then, the first valve is closed, and the second valve is opened, allowing gas to enter the inlet through the second and third connecting pipes. The gas is then discharged into the product under test through the outlet. Because both sides of the product are sealed by the sealing block and gasket, gas leakage is prevented. The pressure is maintained until the pressure reading on the pressure detection component matches the pressure of the detection air source. The second valve is then closed, and a period of time is observed to check for changes in the pressure reading. If no significant change occurs, it indicates that there is no gas leakage within the product under test. Compared to existing technologies, this fixture can quickly perform sealing tests on two-way shut-off valves, with excellent performance. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1 and Figure 2 A sealing test fixture for a two-way shut-off valve includes a base plate 1, a first mounting seat 2 on the base plate 1, a horizontal moving device 3 on the first mounting seat 2, a moving plate 4 on the driving end of the horizontal moving device 3, a mounting seat 5 fixedly mounted on the other side of the moving plate 4, and a sealing block 6 on one side of the mounting seat 5.

[0021] A baffle 7 is provided on the base plate 1, a sealing gasket 8 is provided on one side of the baffle 7, and a second mounting base 9 is provided between the baffle 7 and the horizontal moving device 3.

[0022] The base plate 1 is provided with a first valve 10 and a second valve 11. A first connecting pipe 12 is provided on one side of the first valve 10, and the other side of the first connecting pipe 12 is connected to the horizontal moving device 3.

[0023] An air inlet 13 is provided on one side of the mounting base 5, and an air outlet 14 is provided on one side of the sealing block 6. The air inlet 13 and the air outlet 14 are connected. A second connecting pipe 15 is provided on one side of the second valve 11. A pressure detection component 16 is connected to the other side of the second connecting pipe 15. A third connecting pipe 17 is provided on the other side of the pressure detection component 16. The third connecting pipe 17 is connected to the air inlet 13.

[0024] When using this device, the product to be tested can be placed on the second mounting base 9. An air source is connected to one side of the first valve 10 and the second valve 11. During use, opening the first valve 10 allows air to flow in, driving the drive end of the horizontal moving device 3 to move, causing the sealing block 6 and the sealing gasket 8 to clamp the product to be tested. Then, the first valve 10 is closed, and the second valve 11 is opened to allow gas to enter the air inlet 13 through the second connecting pipe 15 and the third connecting pipe 17, and to be discharged into the product to be tested through the air outlet 14. Since both sides of the product to be tested are sealed by the sealing block 6 and the sealing gasket 8 respectively, gas cannot leak. The process continues until the pressure detection component 16 displays a value consistent with the pressure of the detection air source. Then, the second valve 11 is closed, and after a period of time, the value of the pressure detection component 16 is observed to see if it changes. If the value does not change significantly, it indicates that there is no gas leakage within the product to be tested.

[0025] It should be noted that the reset of the drive end of the horizontal moving device 3 is a known technology (i.e., a cylinder). In this embodiment, only the injection of gas from the first valve 10 is described. The reset of the cylinder drive end can be achieved by alternately supplying gas from both sides of the piston, outputting force in one or two directions (not shown in the figure), or by having a piston rod at only one end, supplying gas from one side of the piston to generate air pressure, which pushes the piston to generate thrust and extend, returning by spring or its own weight (not shown in the figure). Further details will not be elaborated here.

[0026] Furthermore, the pressure detection component 16 is a pressure gauge, and the horizontal movement device 3 is a cylinder. The pressure gauge can be used to observe the pressure value inside the product being tested. The cylinder can be used to move the sealing block 6 to seal the product being tested. After the test is completed, the cylinder piston rod is reset, and the cylinder drives the mounting base 5 and the sealing block 6 to reset.

[0027] Furthermore, the bottom of the base plate 1 is provided with a plurality of feet 18, and the top of each of the feet 18 is provided with a threaded rod 19. The threaded rod 19 is threadedly connected to the bottom of the base plate 1. With the plurality of feet 18 provided, the base plate 1 can be placed on the ground or on a device during use. With the threaded rod 19 provided, the distance between the feet 18 and the base plate 1 can be adjusted by rotating the threaded rod 19, so as to adjust the base plate 1 to a suitable position.

[0028] Furthermore, handles 20 are provided on both sides of the upper part of the base plate 1, and openings 21 are provided on both sides of the handles 20. A screw 22 is provided on one side of the opening 21. The screw 22 passes through the opening 21 and is screwed to the base plate 1. By using the handles 20, the entire base plate 1 can be lifted by holding the handles 20, and the device can be moved to a suitable position. The handles 20 can be disassembled by turning the screws 22, so that it is easy to replace the handles 20 when they are damaged.

[0029] Furthermore, both the sealing block 6 and the sealing gasket 8 are made of silicone, while the base plate 1 and the baffle 7 are made of aluminum. By making the sealing block 6 and the sealing gasket 8 of silicone, the sealing block 6 and the sealing gasket 8 have good flexibility and elasticity, can be stretched and compressed, and are suitable for products of various shapes and sizes, while ensuring a seal. By making the base plate 1 and the baffle 7 of aluminum, the material is lighter and easier to transport manually.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
