[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0017] Reference Figure 1-3 An embodiment of this utility model provides a ball valve airtightness testing device, including a control console 1. The front end of the control console 1 has a through hole 4. A fixed platform 11 is fixedly connected to the front end of the control console 1. Fixed rings 2 are fixedly connected to the left and right sides of the top of the fixed platform 11. A rotating rod 3 is rotatably connected to the inner wall of the fixed ring 2. Fixed rods 7 are fixedly connected to the left and right sides of the front end of the rotating rod 3. An air plate 9 is connected to the rear side of the outer wall of the fixed rod 7 through a fixing assembly. The fixing assembly includes a first fixing plate 8 sleeved on the rear side of the outer wall of the fixed rod 7. A cylinder 6 is fixedly connected to the rear end of the first fixing plate 8. The rear end of the air plate 9 is fixedly connected to the driving end of the cylinder 6. A rotating plate 5 is fixedly connected to the rear end of the cylinder 6. The inner wall of the rotating plate 5 is fixedly connected to the outer wall of the rotating rod 3. Specifically, the cylinder 6 drives the air plate 9 to move and seal the other side of the ball valve. The air plate 9 is connected to an air pump, which can inject gas into the ball valve during the test to cooperate with the pressure detector 16 to detect the airtightness of the ball valve. The operator can press the second fixing plate 10 with his arm to drive the rotating rod 3 to rotate inside the fixing ring 2, so that the entire detection structure is tilted at a certain angle, making the ball valve placement position perpendicular to the operator's arm extension direction, which facilitates the placement of the ball valve and reduces the operator's fatigue during long-term operation.
[0018] A detection component is provided on the front side of the outer wall of the fixed rod 7. The detection component includes a second fixed plate 10 sleeved on the front side of the outer wall of the fixed rod 7. A pressure detector 16 is fixedly connected to the rear end of the second fixed plate 10. Nuts are provided at both the front and rear ends of the second fixed plate 10 and the first fixed plate 8. The inner walls of the nuts are threaded to the outer wall of the fixed rod 7. A control component is provided on the inner wall of the bottom end of the control console 1. The control component includes a sleeve 15 fixedly connected to the inner wall of the bottom end of the control console 1. A pressure block 14 is slidably connected to the inner wall of the sleeve 15. A rotating seat 13 is fixedly connected to the top of the pressure block 14. A connecting rod 12 is rotatably connected to the outer wall of the rotating seat 13. The inner wall of the top end of the connecting rod 12 is rotatably connected to the rear end of the rotating plate 5. Specifically, the position of the second fixing plate 10 can be adjusted by rotating the nut on the fixing rod 7 to accommodate testing of different models of ball valves. At the same time, the second fixing plate 10 and the first fixing plate 8 can be removed from the fixing rod 7 for easy maintenance of the cylinder 6 and the pressure detector 16. The pressure block 14, together with the connecting rod 12 and the rotating seat 13, can control the angle of the entire detection structure to be reset after each test, so that the device can be adapted to the operating habits of different users and ensure that different users can control the tilt angle of the detection structure to place the ball valve more conveniently.
[0019] Working principle: In actual use, the operator can hold the ball valve and push the second fixing plate 10 towards the inside of the fixed platform 11 while seated. This causes the second fixing plate 10 to move the fixing rod 7 downwards, driving the rotating rod 3 to rotate inside the fixed ring 2. This tilts the second fixing plate 10 at a certain angle, ensuring that the operator's outstretched arm is perpendicular to the air pump's placement position. This facilitates the operator placing the ball valve on the pressure detector 16, allowing for seated testing without prolonged standing. During this process, the rotating rod 3 also drives the rotating plate 5 to rotate between the connecting rod 12 and the rotating plate 5. With the cooperation of seat 13, the pressure block 14 rises inside the sleeve 15. After the operator places the ball valve on the pressure detector 16, the cylinder 6 can be activated to push the air plate 9 to move and press against the other end of the ball valve. Then, gas is injected into the ball valve through the pump body connected to the air plate 9 for testing. The operator can observe the pressure gauge set on the control panel 1 to judge whether the air tightness of the ball valve is qualified. After the test is completed, the cylinder 6 controls the air plate 9 to reset. The operator can lift the arm to replace the ball valve. At this time, the pressure block 14 will reset under its own gravity, driving the second fixed plate 10 to move and reset.
[0020] 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.
