Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-4This utility model provides an embodiment of a quick-change fixture for different types of valves, comprising a support plate 1, a sleeve 2 fixedly connected to the middle of the support plate 1, a fixing pipe 4 slidably connected to the middle of the sleeve 2, and a valve body 21 slidably connected to the middle of the fixing pipe 4. The support plate 1 provides stable support for the sleeve 2, allowing the sleeve 2 to better support the fixing pipe 4, thus better fixing the valve body 21 and preventing displacement during valve body 21 testing. A fixing component is installed in the middle of the sleeve 2 to fix the fixing pipe 4. The fixing tube 4 is fixed to better secure the valve body 21 during testing. The fixing component includes a locking block 10, which is fixedly connected to the middle of the sleeve 2. A limiting tube 11 is fixedly connected to the outside of the locking block 10. The sleeve 2 provides support for the locking block 10, allowing it to better support the limiting tube 11 and ensuring its stable operation. A spring 20 is installed inside the limiting tube 11, and a ball bearing 12 is slidably connected to the middle of the limiting tube 11. A slot 13 is provided on the outside of the fixing tube 4, and the slot 13 and the ball bearing 12 are engaged with each other. The limiting tube 11 serves as a support for the ball bearing 12 and the spring. 20 provides support, allowing the ball bearing 12 and spring 20 to work stably. The ball bearing 12 and the slot 13 cooperate to fix the fixed tube 4, preventing displacement of the fixed tube 4 during testing. The spring 20 allows the ball bearing 12 to move within a certain range. Through the cooperation of the various structures of the fixing component, the fixing tube 4 is effectively fixed, allowing the fixed tube 4 to better fix the valve body 21, preventing displacement of the valve body 21 during testing, thereby improving the accuracy of the test. A positioning clamp is fixedly connected to the middle of the fixed tube 4. 8. A fixing groove 7 is provided in the middle of the fixing tube 4. The valve body 21 is slidably connected to the middle of the fixing groove 7. The positioning clamp 8 is in contact with the inner side of the end of the valve body 21. The fixing groove 7 allows the valve body 21 to be placed in the middle of the fixing tube 4. The fixing tube 4 and the positioning clamp 8 cooperate to clamp and fix the valve body 21, so that the valve body 21 will not be displaced during testing. A sliding groove 14 is provided in the middle of the limiting tube 11. The ball 12 is slidably connected to the middle of the sliding groove 14. The ball 12 can move in the middle of the limiting tube 11 through the sliding groove 14.

[0035] Reference Figures 1-6A fixing block 5 is fixedly connected to the end of the fixing pipe 4. The fixing block 5 is in contact with the surface of the valve body 21. The fixing block 5 makes it easier to replace the fixing pipe 4 and limits the valve body 21 to prevent displacement. A through hole 9 is opened in the middle of the fixing pipe 4. A sealing ring 16 is fixedly connected inside the sleeve 2. A sealing groove 17 is opened at the bottom of the fixing pipe 4. The sealing groove 17 and the sealing ring 16 are interlocked. The sleeve 2 provides support for the sealing ring 16, so that the sealing ring 16 can work stably. The sealing ring 16 and the sealing groove 17 cooperate to seal the connection between the sleeve 2 and the fixing pipe 4. A base 15 is fixedly connected to the bottom of the sleeve 2. An installation hole 19 is opened in the middle of the base 15, which provides support for the sleeve 2. The support plate 1 provides support for the sleeve 2 to work stably. The base 15 can be installed on the test bench through the second mounting hole 19, which facilitates the testing of the valve body 21. The sleeve 2 has a groove 3 in the middle, and a fixed tube 4 is slidably connected to the middle of the groove 3. The fixed tube 4 can be placed in the sleeve 2 through the groove 3, so that the fixed tube 4 will not shift during testing. The support plate 1 has a mounting hole 18 in the middle, which can be fixed on the test bench, which facilitates the testing of the valve body 21. The top of both the sleeve 2 and the fixed tube 4 has a limiting groove 6. The valve body 21 is installed in the middle of the limiting groove 6. The limiting groove 6 achieves the limiting effect of the valve body 21, so that the valve body 21 can be stably placed in the middle of the fixed tube 4.

[0036] Working principle: In use, the valve body 21 is inserted into the fixing groove 7 in the fixing tube 4, so that the positioning clamp 8 in the middle of the fixing tube 4 clamps and fixes the valve body 21, so that the valve body 21 can be stably placed in the fixing tube 4. Then, the fixing tube 4 is inserted into the sliding groove 3 in the sleeve 2. At the same time, the fixing tube 4 squeezes the ball 12 to move to the limiting tube 11. When the fixing tube 4 moves to the designated position, the spring 20 pushes the ball 12 to reset, so that the ball 12 and the slot 13 engage, thereby achieving the fixing effect of the fixing tube 4. At the same time, the sealing ring 16 and the sealing groove 17 engage with each other, thereby sealing the connection between the sleeve 2 and the fixing tube 4. Then, through the mounting hole 18 and the mounting hole 2 19, the support plate 1 and the base 15 can be fixed on the test table, thereby realizing the test of the valve body 21.

[0037] When the valve body 21 is inspected, the fixing block 5 is rotated to drive the fixing tube 4 to rotate in the middle of the sleeve 2. This causes the outer wall of the fixing tube 4 to push the ball 12 to move into the limiting tube 11, causing the ball 12 to disengage from the slot 13 and thus releasing the lock on the fixing tube 4. At this time, the fixing block 5 is lifted to disengage the fixing tube 4 from the sleeve 2, and the valve body 21 is pulled to disengage the valve body 21 from the fixing groove 7, thus releasing the lock on the valve body 21. The valve body 21 can then be replaced. The valve body 21 to be inspected is inserted into the corresponding fixing tube 4, and then the fixing tube 4 is reinserted into the sleeve 2 to fix the new valve body 21 to be inspected. The valve body 21 to be inspected can then be inspected.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
