Specifically, the base plate 1 supports the entire device, the testing platform 2 of the base plate 1 provides fixed support, the testing platform 2 supports and fixes the support frame 3, the support frame 3 supports the testing device, the support frame 3 fixes the fixing box 4, the fixing box 4 is used for mechanical limiting, and the fixing box 4 fixes the hydraulic rod 5. By activating the hydraulic rod 5, the sliding block 6 can be driven to slide. The sliding block 6 slides on the outer wall of the limiting strip 7, and the limiting strip 7 limits the sliding block 6. The sliding block 6 can drive the sliding shaft 8 to slide. The sliding block 6 has a groove inside that limits the sliding shaft 8. The sliding shaft 8 can drive the connecting plate 9 to slide. The connecting plate 9 slides inside the limiting plate 10, and the limiting plate 10 limits the connecting plate 9. The connecting plate 9 can drive the testing plate 11 to move. The testing plate 11 can test the air tightness of the pipeline valve. When the testing plate 11 squeezes the pipeline valve, it can seal the valve and then perform an air tightness test.

[0020] Reference Figure 2 The storage component 12 includes a water tank 1201, the lower surface of the water tank 1201 is fixedly connected to the upper surface of the base plate 1, a water pump 1202 is fixedly connected to the upper surface of the water tank 1201, and a placement platform 1203 is fixedly connected to the output end of the water pump 1202. Specifically, a storage component 12 is provided above the base plate 1. The storage component 12 is used to store water for testing the airtightness of the valve. The water tank 1201 stores test water inside. A water pump 1202 is provided above the water tank 1201. The water pump 1202 can supply water to the valve placement platform 1203. The interior of the placement platform 1203 is hollow and connected to the opening end of the valve. When the water pump 1202 is started, it can supply water to the valve.

Specifically, a water cylinder 14 is installed above the base plate 1, and a water pipe 13 is installed above the water cylinder 14. The water pipe 13 can be used to test the airtightness of the valve. If the valve is airtight, when the water pump 1202 is started, the water source will not enter the detection plate 11 through the valve, but will instead enter the water cylinder 14 through the water pipe 13. If the valve is not airtight, the water pump 1202 can drive the water source from the valve into the detection plate 11, and then into the water cylinder 14. The airtightness of the valve is tested by observing whether water flows into the water cylinder 14.

[0022] Example 2: Reference Figure 4 The output end of the hydraulic rod 5 is provided with a sliding component 15, which includes an inclined block 1501.

The outer wall of the first spring 16 is fixedly connected to the upper surface of the support frame 3. Specifically, when the valve of the detection plate 11 is pressed down, the structure can be replaced. By activating the hydraulic rod 5, the inclined block 1501 can be driven to slide. The inclined block 1501 can drive the roller 1502 to slide on the outer wall of the inclined block 1501. The roller 1502 can drive the connecting plate 9 to slide on the outer wall of the sliding shaft 8, thereby driving the detection plate 11 to move. At the same time, a first spring 16 is provided above the detection plate 11 to ensure the stability of the sliding of the inclined block 1501.

[0023] Example 3: Reference Figure 5 and Figure 6A bracket 17 is fixedly connected to the upper surface of the testing table 2. A motor 18 is fixedly connected inside the testing table 2. A lead screw 19 is fixedly installed at the output end of the motor 18. The outer wall of the lead screw 19 is rotatably connected to the inside of the bracket 17. A moving block 20 is threadedly connected to the outer wall of the lead screw 19. A limit block 21 is slidably connected inside the moving block 20. The outer wall of the limit block 21 is fixedly connected to the inside of the bracket 17. A slider 22 is slidably connected to the outer wall of the moving block 20. A fixed plate 23 is fixedly connected to the outer wall of the slider 22. A limit post 24 is fixedly connected to the outer wall of the fixed plate 23. The outer wall of the limit post 24 is slidably connected to the inside of the bracket 17. A vertical plate 25 is slidably connected to the outer wall of the limit post 24. The lower surface of the vertical plate 25 is fixedly connected to the upper surface of the testing table 2. A clamping block 26 is slidably connected to the outer wall of the limit post 24. A second spring 27 is provided on the outer wall of the limit post 24. One end of the second spring 27 is fixedly connected to the outer wall of the clamping block 26, and the other end of the second spring 27 is fixedly connected to the outer wall of the vertical plate 25. Specifically, the testing platform 2 fixes the bracket 17, which in turn supports the clamping device. The testing platform 2 also fixes the motor 18. Starting the motor 18 drives the lead screw 19 to rotate inside the bracket 17, which in turn supports the lead screw 19. The rotation of the lead screw 19 causes the moving block 20 to slide against the outer wall of the limiting block 21, which limits the movement of the moving block 20. The moving block 20 then causes the slider 22 to slide, which in turn causes the fixed plate 23 to move, and the fixed plate 23 then moves the limiting plate 21. Positioning post 24 slides inside bracket 17. Due to the inclined shape of moving block 20, when moving block 20 slides, it can drive the sliders 22 on both sides to move to both ends, which in turn can drive the clamping block 26 connected to slider 22 to move. At the same time, it can drive the clamping block 26 connected to limiting post 24 to move. While the two clamping blocks 26 are moving, the second spring 27 can be driven to apply pressure between clamping block 26 and vertical plate 25 to maintain the stability of clamping block 26 movement. Thus, the clamping block 26 can achieve the effect of fixing and clamping the valve, avoiding displacement during detection and affecting the detection results.

[0024] Working principle: When this testing device is needed, the pipeline valve can first be placed on the upper surface of the water pump 1202 and then clamped and fixed. By starting the motor 18, the lead screw 19 can be driven to rotate inside the bracket 17. While the lead screw 19 is rotating, the moving block 20 can be driven to slide on the outer wall of the limiting block 21. The sliding of the moving block 20 can drive the slider 22 to move. When the slider 22 moves, it can drive the fixing plate 23 to move. The fixing plate 23 can drive the limiting column 24 to slide inside the hydraulic rod 5 and the bracket 17. While the limiting column 24 is sliding, it can drive the two clamping blocks 26 to slide towards each other, and at the same time drive the second spring 27 to be compressed, thereby driving the clamping blocks 26 to clamp the pipeline valve to ensure the stability of subsequent testing and avoid deviation during testing, which would affect the test results. After the pipeline valve is fixed, activating the hydraulic rod 5 causes the sliding block 6 to slide on the outer wall of the limiting strip 7, which in turn causes the sliding shaft 8 to slide inside the sliding block 6. As the sliding shaft 8 slides, it causes the connecting plate 9 to slide inside the limiting plate 10. The sliding of the connecting plate 9 causes the detection plate 11 to press downwards on the valve until it is tightly fitted with the valve, ensuring a tight fit between the valve and the placement platform 1203. Additionally, activating the hydraulic rod 5 can cause the inclined block 1501 to slide on the outer wall of the limiting strip 7, which in turn causes the roller 1502 to slide on the outer wall of the inclined block 1501, simultaneously driving the sliding... The sliding of shaft 8 causes the connecting plate 9 to move, thereby causing the detection plate 11 to squeeze the valve. At this time, the water pump 1202 can be started to drive the water source from the inside of the water tank 1201 into the placement platform 1203 to supply water to the valve. The water then enters the water pipe 13 through the detection plate 11 and then enters the water cylinder 14 from the water pipe 13. It is observed whether water enters the water cylinder 14. If no water enters, the valve has good airtightness; otherwise, the airtightness is poor. This detection device can clamp and fix the valve to ensure the accuracy of the detection and can also perform airtightness detection on the valve, thus improving the efficiency of the detection.
