The groove 33 is provided at the rear end of the side plate 25, and the top end of the side plate 25 is rotatably connected to the rotating shaft 22. The side plate 25 is provided with multiple groups, and the bottom end of the side plate 25 is fixedly connected to the connecting plate 31, and the side plate 25 is fixedly connected to the bottom plate 29, and the bottom plate 29 is fixedly connected to the cylinder 28. The rear end of the support frame 24 abuts against the top end of the support plate 32, and the bottom end of the side plate 25 is provided with a supporting mechanism;

[0035] Through the structural design of the rotating mechanism, not only can multiple groups of valves be inspected at the same time, but also during the inspection, the rotating frame 23 brings the valve underwater by rotating. When the valve is completely submerged, the position of the valve in the water is relatively shallow. At the same time, the top of the rotating frame 23 will not block the valve, so that the inspection personnel can observe it. During operation, when the valve is to be inspected, the hydraulic rod 42 is first started. The hydraulic rod 42 pulls the rotating frame 23 downward through the pulling rod 41. The rotating frame 23 rotates on the rotating shaft 22 until the rotating frame 23 rotates to a horizontal state, and then the valve is placed on the connecting plate 31. After the cylinder 28 is started, the valve can be fixed on the connecting plate 31. At this time, the pulling rod 41 is pushed upward by the hydraulic rod 42 again, and the pulling rod 41 drives the rotating frame 23 to rotate. During the rotation process, the rotating frame 23 will The valve is put into water. When the rotating frame 23 rotates to the maximum angle, the rear end of the support frame 24 will abut against the top of the support plate 32. The support plate 32 can provide support for the rotating frame 23 by abutting against the support frame 24. During detection, gas is passed into the valve. If the valve sealing is not up to standard or there is a leak, bubbles will be generated on the valve. The cylinder 28 can be set in multiple groups according to actual needs to facilitate the detection of multiple valves at the same time. The hydraulic rod 42 is fixed on the rear end of the device body 1 and a mounting groove corresponding to the hydraulic rod 42 is opened at the rear end of the device body 1. The mounting groove is designed in an arc shape so that the rear end of the device body 1 can fit the surface of the hydraulic rod 42, and the hydraulic rod 42 is installed and fixed. The support frame 24 abuts against the inner wall of the groove 33 so that the side plate 25 can be supported by the support frame 24.

[0036] Further, the supporting mechanism includes a gear 36, which is rotatably connected to the bottom end of the side plate 25, one side of the gear 36 is fixedly connected to a connecting rod 37, and the connecting rod 37 is fixedly connected to a supporting plate 38. A slot 35 is provided at a position near the bottom end of the side plate 25, and the length of the slot 35 is adapted to the length of the connecting rod 37. A plurality of groups of arc plates 39 are fixedly connected to the top of the device body 1, and tooth grooves corresponding to the gear 36 are provided on the arc plates 39;

[0037] Through the structural design of the supporting mechanism, when the rotating frame 23 rotates to a horizontal state, the supporting plate 38 on the bottom end of the side plate 25 will also rotate to a horizontal state. At this time, the supporting plate 38 is located below the valve. When the cylinder 28 releases the clamping of the valve, even if the tester slips or does not hold it firmly when removing the valve, the valve will not fall directly into the device body 1. During operation, a gear 36 rotates on the bottom end of the side plate 25. When the rotating frame 23 is rotated to remove the valve, the cylinder 28 will rotate together with the rotating frame 23, and the gear 36 will mesh with the arc plate 39. Thereby, the gear 36 is driven to rotate through the arc plate 39, and a connecting rod 37 is fixed to the gear 36. When the rotating frame 23 and the cylinder 28 rotate to a horizontal state, the connecting rod 37 will also rotate to a horizontal position, and the support plate 38 will be below the valve. At this time, when the cylinder 28 releases the fixation on the valve, if the inspector fails to hold the valve firmly in the first time, the valve will fall down. However, since the support plate 38 is located below the valve, the valve will directly fall onto the support plate 38, which is convenient for the inspector to pick up the fallen valve, and the support plate 38 can prevent the valve from continuing to fall.

[0038] Furthermore, a reinforcing plate 34 is fixedly connected to the front end of the side plate 25. The reinforcing plate 34 is trapezoidal in design and is located directly above the notch 35.

[0039] When working, the reinforcing plate 34 is located directly above the notch 35 , and the reinforcing plate 34 can improve the strength of the notch 35 . At the same time, the reinforcing plate 34 is trapezoidal in design, and when the cylinder 28 is pulled to rotate alone, the reinforcing plate 34 can facilitate the inspection personnel to hold the side plate 25 .

[0041] Through the structural design of the fixing mechanism, during the detection process, the fixation between the bottom end of the bottom plate 29 and the top end of the support frame 24 will be released. At this time, the cylinder 28 can be smoothly pulled to facilitate the removal of the valve fixed by the group of cylinders 28 from the water. When a valve with unqualified air tightness is detected, the valve can be removed from the connecting plate 31 in time, and other valves to be detected can be placed in order to improve the detection efficiency of the device. During operation, the cylinder 28 can rotate with the rotating frame 23, and can also be pulled alone to rotate it. The protrusion 43 is fixed on the bottom plate 29 and inserted in the slot 49. When the support frame 24 abuts against the support plate 32, the top end of the support plate 32 is fixed. The top block 48 will also be inserted into the slot 49 and abut against the two groups of card blocks 45. The top block 48 will push the card blocks 45 to both sides, and the card blocks 45 will slide in the movable groove 47. The connecting spring 46 fixed on the card block 45 will be compressed, and part of the card block 45 inserted in the card slot 44 will be received in the movable groove 47. At this time, the protrusion 43 can smoothly slide out of the slot 49. At this time, when the side plates 25 on both sides of the cylinder 28 are pulled, the side plates 25 can smoothly rotate on the rotating shaft 22. When the rotating frame 23 drives the cylinder 28 to move together, the card block 45 is inserted in the card slot 44 so that the protrusion 43 cannot slide out of the slot 49, and the protrusion 43 is also fixed in the slot 49.

The bottom end of the support rod 53 is rotatably connected to the connecting block 54. When the connecting block 54 slides inside the sliding groove 51, the supporting spring 55 will also provide support for the bottom end of the connecting block 54. With the support of the supporting spring 55, it will be more labor-saving when pulling the cylinder 28.

[0044] Furthermore, both left and right sides of the support plate 32 are provided with through slots 56 , which are designed in a long rectangular shape and penetrate the support plate 32 ;

[0045] During operation, the through groove 56 is opened on the support plate 32 and passes through the support plate 32.
