Description

Technical Field

[0001] The utility model relates to the technical field of sealing performance testing, in particular to a sealing performance testing device for a ceramic ball valve. Background Art

[0002] When producing a ceramic ball valve, in order to ensure the product quality, it is necessary to test the sealing effect of the ceramic ball valve. The sealing performance testing device for a ceramic ball valve is mainly used to detect whether there is a leakage phenomenon between the inside and the outside medium when the ceramic ball valve is in the closed state.

[0003] When the existing sealing performance testing device for a ceramic ball valve detects the sealing performance of the ceramic ball valve, in order to avoid air leakage during the detection, clamps are required to seal both ends of the ceramic ball valve. Therefore, the clamp can only hold and fix ceramic ball valves of a fixed size. Once a ceramic ball valve that is too large or too small is clamped, air leakage will occur, thus affecting the detection effect of the sealing performance of the ceramic ball valve. Therefore, it does not have the function of holding ceramic ball valves of different sizes. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a sealing performance testing device for a ceramic ball valve to solve the problem that the existing sealing performance testing device for a ceramic ball valve does not have the function of holding ceramic ball valves of different sizes as mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A sealing performance testing device for a ceramic ball valve, comprising: a detection pool and an air pump. A clamp is arranged at the top of the detection pool. A chuck is installed on one side of the clamp. A ball valve body is arranged between the two chucks. One side of the chuck is connected through a gas guiding hose. The air pump is connected to one side of the gas guiding hose away from the chuck;

[0006] A fixing block is installed on one side of the chuck, and a first screw rod passes through the middle of the fixing block.

[0007] Preferably, the bottom of the first screw rod is connected to a connecting block through a bearing, and a second screw rod passes through the middle of the connecting block.

[0008] Preferably, one side of the second screw rod is connected to a clamping block through a rotating shaft, and guide rods are connected to one end of both the clamping block and the connecting block.

[0009] Preferably, a sealing rubber ring is installed on the inner wall of the chuck.

[0010] Preferably, a connecting rod is installed at the top of the two clamps, and a cylinder is installed at the top of the connecting rod.

[0011] Preferably, a fixing frame is installed at the top of the cylinder, a slider is installed on one side of the fixture, and a guide rail is installed on one side of the slider.

[0012] Preferably, the guide rail is installed on the inner wall of the detection pool, and two groups of guide rails are symmetrically installed about the center line of the detection pool.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the ceramic ball valve sealing performance testing device is in use, the ceramic ball valve can be placed between two groups of chucks, and then according to the size of the ceramic ball valve, the first screw is rotated, so that the first screw drives the connecting block to move through the guide rod. After adjusting the connecting block to the corresponding position of the ceramic ball valve, the second screw is rotated, so that the second screw drives the clamping block to move towards the ceramic ball valve through the guide rod. Through the clamping block, the ceramic ball valve can squeeze the sealing rubber ring in the chuck, and the sealing rubber ring will play a sealing role in the gap between the ceramic ball valve and the chuck after being squeezed, so as to clamp and limit ceramic ball valves of different sizes, which is the usage feature of the ceramic ball valve sealing performance testing device.

[0014] 1. For the ceramic ball valve sealing performance testing device, when it is necessary to detect the ceramic ball valve, the first screw and the second screw can be rotated in sequence, so that the first screw and the second screw drive the clamping block to move. Through the clamping block, the ceramic ball valve can be clamped on one side of the chuck and squeeze the sealing rubber ring, which can not only improve the sealing effect of the ceramic ball valve, but also meet the detection requirements of ceramic ball valves of different sizes.

[0015] 2. For the ceramic ball valve sealing performance testing device, when detecting the sealing performance of the ceramic ball valve, the cylinder can be started, so that the cylinder drives the fixture to move downward through the connecting rod. When the fixture moves downward, it will drive the ceramic ball valve to move into the detection pool through the chuck, and move along the guide rail through the sliders on both sides of the fixture, thereby increasing the stability of the ceramic ball valve during movement and avoiding the shaking of the ceramic ball valve from affecting the sealing effect.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1 And Figure 2 , the present invention provides a technical solution: a ceramic ball valve sealing performance testing device, including: a detection pool 1 and an air pump 6. A fixture 2 is arranged on the top of the detection pool 1. A chuck 3 is installed on one side of the fixture 2. A ball valve body 4 is arranged between two chucks 3. One side of the chuck 3 is connected through an air guide hose 5. The air pump 6 is connected to one side of the air guide hose 5 away from the chuck 3;

[0024] A fixed block 7 is installed on one side of the chuck 3. A first screw 8 penetrates through the middle of the fixed block 7. The bottom of the first screw 8 is connected to a connecting block 9 through a bearing. A second screw 10 penetrates through the middle of the connecting block 9. One side of the second screw 10 is connected to a clamping block 11 through a rotating shaft. Guide rods 12 are connected to one ends of the clamping block 11 and the connecting block 9 respectively. A sealing rubber ring 13 is installed on the inner wall of the chuck 3. Three groups of fixed blocks 7 are symmetrically installed about the center line of the chuck 3.

[0025] During specific implementation, when the ceramic ball valve sealing performance testing device detects the sealing performance of the ceramic ball valve, the ceramic ball valve can be placed in the middle position between two chucks 3. Then rotate the fixture 2. The fixture 2 is composed of a threaded rod and a smooth rod. When rotating the threaded rod, with the cooperation of the smooth rod, the chuck 3 can be driven to move towards the ceramic ball valve. At this time, the chuck 3 can initially clamp the ceramic ball valve;

[0026] Then, according to the size of the ceramic ball valve, rotate the first screw rod 8 in the middle of the fixed block 7. Since the first screw rod 8 is threadedly connected to the fixed block 7, and the first screw rod 8 is connected to the connecting block 9 through a bearing, and a guide rod 12 passing through the fixed block 7 is also connected to the top of the connecting block 9. Therefore, when rotating the first screw rod 8, under the guiding action of the guide rod 12 on the connecting block 9, the connecting block 9 will move up and down along the direction of the first screw rod 8, so as to adjust the clamping position of the ceramic ball valve on the side of the chuck 3;

[0027] Then rotate the second screw rod 10 on one side of the connecting block 9. Since the second screw rod 10 is threadedly connected to the connecting block 9, and the second screw rod 10 is connected to the clamping block 11 through a bearing. Similarly, one side of the clamping block 11 is connected with a guide rod 12 passing through the connecting block 9. Under the guiding action of the guide rod 12 on the clamping block 11, when the second screw rod 10 rotates, it will drive the clamping block 11 to move left and right, so that the clamping block 11 can push the ceramic ball valve towards the chuck 3. At the same time, the ceramic ball valve will squeeze the sealing rubber ring 13 on the inner wall of the chuck 3. When the sealing rubber ring 13 is squeezed, it will deform, so as to seal the gap between the chuck 3 and the ceramic ball valve, so that the ceramic ball valve will not affect the test effect during the sealing test. At the same time, the position of the clamping block 11 can be adjusted by the first screw rod 8 and the second screw rod 10, so as to clamp and limit ceramic ball valves of different sizes, meeting the different use requirements of users.

[0028] Refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 It can be known that during use, the ceramic ball valve to be detected can be placed between the two groups of chucks 3, and according to the position of the ceramic ball valve, the ceramic ball valve can be clamped and fixed by rotating the first screw rod 8 and the second screw rod 10, so as to meet the needs of users to detect ceramic ball valves of different sizes.

[0029] Two connecting rods 14 are installed on the top of the two groups of jigs 2. A cylinder 15 is installed on the top of the connecting rod 14. A fixed frame 16 is installed on the top of the cylinder 15. A slider 17 is installed on one side of the jig 2. A guide rail 18 is installed on one side of the slider 17. The guide rail 18 is installed on the inner wall of the detection pool 1. Two groups of guide rails 18 are symmetrically installed about the center line of the detection pool 1. The fixed frame 16 is installed on the top of the detection pool 1.

[0030] During specific implementation, for the ceramic ball valve sealing test device, when it is necessary to detect the sealing performance of the ceramic ball valve, the ceramic ball valve can be fixed between two sets of chucks 3 through two sets of fixtures 2. Then, the air cylinder 15 is started, causing the air cylinder 15 to drive the connecting rod 14 to move downward. Both bottom ends of the connecting rod 14 are connected to the fixture 2. Therefore, when the air cylinder 15 moves downward, it will drive the fixture 2 to move downward through the connecting rod 14. At the same time, the fixture 2 will drive the intermediate ceramic ball valve to move downward through the chuck 3. A slider 17 is installed on one side of the fixture 2. When the fixture 2 moves downward, it will cause the slider 17 to move downward along the guide rail 18. At the same time, the guide rail 18 is installed on the inner wall of the detection pool 1. With the cooperation of the guide rail 18 and the slider 17, the fixture 2 moves more stably downward, thus preventing the fixture 2 from shaking and affecting the sealing effect of the ceramic ball valve. And the stability of the air cylinder 15 can be increased through the fixing frame 16 at the top of the air cylinder 15, making it less likely for the air cylinder 15 to shake. When the fixture 2 drives the ceramic ball valve to move into the detection pool 1 through the chuck 3, the sealing performance of the ceramic ball valve can be detected.

[0031] Refer to Figure 1 , Figure 2 and Figure 3 As can be seen, when detecting the sealing performance of the ceramic ball valve, the air cylinder 15 can be started. With the cooperation of the air cylinder 15 and the connecting rod 14, the connecting rod 14 drives the ceramic ball valve to move downward through the fixture 2 and the chuck 3. At the same time, the cooperation of the slider 17 and the guide rail 18 can increase the stability of the ceramic ball valve, making it less likely for the ceramic ball valve to shake.

[0032] In summary: When the ceramic ball valve sealing test device is in use, the ceramic ball valve to be detected can be clamped between two sets of chucks 3 through the fixture 2, and then the clamping block 11 is driven by the first screw rod 8 and the second screw rod 10 to fix the ceramic ball valve. At this time, the air cylinder 15 is started, causing the air cylinder 15 to drive the ceramic ball valve to move into the detection pool 1 through the connecting rod 14 and the fixture 2. When the ceramic ball valve moves into the detection pool 1, the air pump 6 is started, and the air pump 6 can deliver gas to the ceramic ball valve through the air guide hose 5 and the chuck 3. When the ceramic ball valve leaks, the gas inside the ceramic ball valve will flow out from the leaking position, causing bubbles to appear on the water surface inside the detection pool 1. At this time, it indicates that the ceramic ball valve has a leakage situation. On the contrary, if there are no bubbles on the water surface inside the detection pool 1, it means that the sealing effect of the ceramic ball valve is intact. This is the usage feature of the ceramic ball valve sealing test device. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0033] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
