[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] Reference Figures 1-8 A valve leak detection device includes a detection box 1, a placement platform 2 fixedly connected to the upper surface of the detection box 1, a valve body 3 placed on the upper surface of the placement platform 2, an electric push rod 4 fixedly connected inside the detection box 1, a sliding plate 5 fixedly connected to the output end of the electric push rod 4, a rotating shaft 6 rotatably connected inside the sliding plate 5, a rotating plate 7 fixedly connected to the outer wall of the rotating shaft 6, a connecting shaft 8 rotatably connected inside the rotating plate 7, a rotating plate 9 fixedly connected to the outer wall of the connecting shaft 8, a rotating shaft 10 rotatably connected inside the rotating plate 9, and the outer wall of the rotating shaft 10 fixedly connected inside the detection box 1, a limiting post 11 slidably connected inside the sliding plate 5, the outer wall of the limiting post 11 fixedly connected inside the detection box 1, a connecting pipe 12 fixedly connected to the outer wall of the sliding plate 5, and a detection component 13 provided on the upper surface of the detection box 1.

[0033] The valve leak detection device provided by this utility model is used as follows: When it is necessary to test the leak prevention function of the valve body 3, first connect the two ends of the valve and place the valve body 3 on the upper surface of the placement platform 2. At this time, by starting the electric push rod 4, the sliding plate 5 can be driven to slide on the outer wall of the limiting post 11. When the sliding plate 5 slides, it can drive the rotating shaft 6 to move. The rotating shaft 6 can drive the rotating plate 7 to rotate on the outer wall of the connecting shaft 8. Then the connecting shaft 8 drives the rotating plate 9 to rotate on the outer wall of the rotating shaft 10. At this time, the sliding plates 5 on both sides of the placement platform 2 can be driven to slide simultaneously towards the placement platform 2. The outer walls of the two sliding plates 5 are connected to the connecting pipes 12. When the sliding plates 5 move, they can drive the connecting pipes 12 to be connected to the two ends of the valve body 3 respectively, so as to carry out leak prevention detection later and improve the efficiency of valve detection.

[0034] Reference Figure 2 The detection component 13 includes a booster pump 1301. The lower surface of the booster pump 1301 is fixedly connected to the upper surface of the detection box 1. An air inlet pipe 1302 is fixedly provided at the output end of the booster pump 1301. The other end of the air inlet pipe 1302 is fixedly connected to the inside of the connecting pipe 12.

[0035] Reference Figure 3 An air outlet pipe 14 is fixedly connected inside the connecting pipe 12, and a limit frame 15 is fixedly connected to the upper surface of the detection box 1, with the air outlet pipe 14 located inside the limit frame 15.

[0036] The valve leak detection device provided by this utility model is used as follows: After the connecting pipe 12 is connected to the valve body 3, the valve body 3 can be leak-proof tested by the detection component 13. An air outlet pipe 14 and an air inlet pipe 1302 are respectively connected inside the two connecting pipes 12. One end of the air inlet pipe 1302 is connected to the output end of the booster pump 1301. By starting the booster pump 1301, air is supplied to the air inlet pipe 1302. At this time, the air outlet pipe 14 is placed inside the detection box 1 after water is injected. Observe whether air bubbles are generated to determine whether the valve body 3 is leaking. If air bubbles are generated, it proves that the valve is leaking. If no air bubbles are generated, it is not leaking. Note that the valve body 3 should always be kept closed during the test.

[0037] Reference Figures 5-8The inside of the test box 1 is slidably connected to a cover plate 16, and the inside of the cover plate 16 is slidably connected to a locking block 17. The outer wall of the locking block 17 is locked inside the test box 1. The inside of the locking block 17 is slidably connected to a wedge block 18, and the outer wall of the wedge block 18 is slidably connected to the inside of the cover plate 16. The outer wall of the wedge block 18 is fixedly connected to a connecting plate 19. The outer wall of the connecting plate 19 is fixedly connected to a sliding column 20, and the outer wall of the sliding column 20 is slidably connected to the inside of the cover plate 16. The outer wall of the sliding column 20 is fixedly connected to a pull ring 21. A spring 22 is sleeved on the outer wall of the sliding column 20. One end of the spring 22 is fixedly connected to the outer wall of the connecting plate 19, and the other end of the spring 22 is fixedly connected to the inside of the cover plate 16.

[0038] In this embodiment, each structure has its own service life. In actual manufacturing and application, the corresponding structure made of different materials can be replaced according to the needs of use.

[0039] The valve leak detection device provided by this utility model is used as follows: The lower half of the detection box 1 is set as a water tank for water injection to assist detection. When not in use, the cover plate 16 is set to cover the water surface to prevent pollution from affecting the detection. The water source can be tested multiple times to avoid waste. When the cover plate 16 needs to be opened, the pull ring 21 is pulled to drive the sliding column 20 to slide inside the cover plate 16. At this time, the spring 22 is compressed, which can drive the connecting plate 19 to slide, and then drive the inclined block 18 to slide inside the locking block 17. When the inclined block 18 slides, it can drive the locking block 17 to slide out of the detection box 1, thus achieving the effect of protecting the water source.
