[0024] The following is combined with Figure 1 -Attached Figure 4 This application is described in further detail.

[0025] The present application embodiment discloses a valve leakage detection device. Figure 1-Figure 4 A valve leakage detection device comprises a support plate 1, support legs 2 are fixed at the four corners of the bottom of the support plate 1, a pair of support rods 3 are also passed through the support plate 1, a first placement plate 5 is fixed to the top of the pair of support rods 3, a first nut 4 is installed at the bottom through a thread, a reset spring 6 is also sleeved on the outer wall of the pair of support rods 3, and the reset spring 6 is located between the first placement plate 5 and the support plate 1, two rows of hexagonal grooves 7 are also opened on the top of the first placement plate 5, two exhaust pipes 8 are also fixed to the bottom of the first placement plate 5, and the exhaust pipes 8 are communicated with the hexagonal grooves 7, and a pair of water tanks 9 are also installed on the top of the support plate 1 below the two exhaust pipes 8;

[0026] The four corners of the top of the support plate 1 are fixed with legs 12, and the support plate 1 is fixed with a top plate 26 through the four legs 12. The top plate 26 is also fixed with a cylinder 13, and the output end of the cylinder 13 passes through the top plate 26 and is installed with a detachable second storage plate 14, and two rows of air intake pipes 20 are rotatably connected to the second storage plate 14. An air pump 23 and a pair of air tightness detectors 24 are fixed on the top of the top plate 26. The output end of the air pump 23 is connected to the two air tightness detectors 24 through a hose, and a row of air delivery pipes 25 are fixed on the pair of air tightness detectors 24, and one end of the air delivery pipe 25 is connected to the air intake pipe 20 through a clamp;

[0027] A pair of screw rods 15 are fixed on the top of the second placement plate 14, and a connecting plate 17 is fixed on the outer wall of the output end of the cylinder 13. A pair of avoidance grooves 18 for the screw rods 15 to pass through are opened on the connecting plate 17. The outer walls of the pair of screw rods 15 are both threadedly mounted with second nuts 16, and a sleeve 19 is also fixed on the top of the second placement plate 14. When in use, first, one end of the valve can be threadedly mounted on the air inlet pipe 20, and then the cylinder 13 is started to push the second placement plate 14 to move downward, and the other end of the valve can be placed on the hexagonal groove 7, and the diameter of the hexagonal groove 7 is slightly larger than the diameter of the valve, so that one end of the valve is conveniently embedded in the hexagonal groove 7. In addition, through the precise control of the cylinder 13, the second placement plate 14 can be stably and accurately moved to the predetermined position, thereby ensuring that the valve is in contact with the air inlet pipe 20 and the air outlet pipe. The connection between the two is tight and reliable. During use, by starting the cylinder 13, the second storage plate 14 is used to push the valve and the first storage plate 5 to move downward at the same time, so that one end of the air outlet pipe 8 can be located inside the water tank 9, and then the air pump 23 is started. The air pump 23 conveys the gas to the two air tightness detectors 24 through the hose, and then conveys it to the air inlet pipe 20 through the air delivery pipe 25, and finally enters the air outlet pipe 8 through the valve. When the gas passes through the valve and is discharged from the air outlet pipe 8, there is a leakage. If there is a leakage, the gas will escape from the connection between the valve and the air outlet pipe 8 and enter the water tank 9. By observing whether bubbles appear in the water tank 9, it can be judged whether the valve is leaking. This design not only facilitates users to detect the leakage of the valve, but also improves the accuracy and reliability of the detection.

[0028] When it is necessary to test valves of different sizes, the user only needs to rotate the second nut 16 counterclockwise to disengage it from the screw 15, and then pull the screw 15 out of the connecting plate 17, so that the second placement plate 14 can be easily disassembled. The replaced second placement plate 14 is provided with an air inlet pipe 20 of corresponding size. At the same time, the first nut 4 is rotated counterclockwise to disengage it from a pair of support rods 3, and then the support rods 3 are pulled out from the support plate 1, so that the first placement plate 5 can be replaced to meet the testing needs of valves of different sizes. The replaced first placement plate 5 is provided with a hexagonal groove 7 and an air outlet pipe 8 of corresponding size, ensuring that the valve can be stably placed on the first placement plate 5 and tightly connected with the air outlet pipe 8. The design of this convenient disassembly mechanism greatly improves the practicality and flexibility of the device.

[0029] Reference Figure 2 The water tank 9 is made of transparent plastic material; the transparent plastic material makes the water tank 9 have good visibility, and the user can visually observe whether bubbles appear inside the water tank 9, thereby accurately judging whether there is a leak in the valve.

[0030] Reference Figure 2 A plurality of isolation plates 10 are evenly spaced on a pair of water tanks 9, and an elastic sheet 11 is fixed on one side of the isolation plate 10; the equidistant arrangement of the isolation plates 10 can effectively divide the water tank 9 into a plurality of independent areas, so that each area can independently observe and judge whether there is a valve leak, and the elastic sheet 11 can be clamped on the outer wall of the water tank 9, which can effectively prevent the isolation plate 10 from being displaced or falling off due to external force during the detection process.

[0031] Reference Figure 1 , the air outlet pipe 8 is a bellows; the design of the bellows makes the air outlet pipe 8 have a certain elasticity and flexibility, and can maintain stable performance in harsh working environments.

[0032] Reference Figure 2 and Figure 4 A support plate 21 is fixed to the top surface of the first storage plate 5 near the hexagonal groove 7, and an arc groove 22 is opened on the top surface of the support plate 21; the arc groove 22 can be used to support one side of the valve to prevent it from shaking.

[0033] Reference Figure 4 The screw rod 15, the second nut 16, and the connecting plate 17 are made of metal; they are not easy to break or bend, and the service life is extended.

[0034] Reference Figure 2 , the height of the support rod 3 is greater than the height of the water tank 9, which facilitates the downward movement of the first storage plate 5.

[0035] The implementation principle of a valve leakage detection device according to an embodiment of the present application is as follows: when in use, first, one end of the valve can be installed on the air inlet pipe 20 through a thread, and then the cylinder 13 is started to push the second placement plate 14 to move downward, and the other end of the valve can be placed on the hexagonal groove 7, and the diameter of the hexagonal groove 7 is slightly larger than the diameter of the valve, so that one end of the valve can be easily embedded in the hexagonal groove 7. In addition, through the precise control of the cylinder 13, the second placement plate 14 can be stably and accurately moved to a predetermined position, thereby ensuring that the connection between the valve and the air inlet pipe 20 and the air outlet pipe 8 is tight and reliable;

[0036] During use, by starting the cylinder 13, the second placement plate 14 is used to push the valve and the first placement plate 5 to move downward at the same time, so that one end of the air outlet pipe 8 can be located inside the water tank 9, and then the air pump 23 is started. The air pump 23 conveys the gas to the two air tightness detectors 24 through the hose, and then conveys the gas to the air inlet pipe 20 through the air delivery pipe 25, and finally enters the air outlet pipe 8 through the valve. When the gas passes through the valve and is discharged from the air outlet pipe 8, there is a leakage. If there is a leakage, the gas will escape from the connection between the valve and the air outlet pipe 8 and enter the water tank 9. By observing whether bubbles appear in the water tank 9, it can be judged whether the valve is leaking. This design not only facilitates the user to detect the leakage of the valve, but also improves the accuracy and reliability of the detection.

[0037] When it is necessary to test valves of different sizes, the user only needs to rotate the second nut 16 counterclockwise to disengage it from the screw 15, and then pull the screw 15 out of the connecting plate 17, so that the second placement plate 14 can be easily disassembled. The replaced second placement plate 14 is provided with an air inlet pipe 20 of corresponding size. At the same time, the first nut 4 is rotated counterclockwise to disengage it from a pair of support rods 3, and then the support rods 3 are pulled out from the support plate 1, so that the first placement plate 5 can be replaced to meet the testing needs of valves of different sizes. The replaced first placement plate 5 is provided with a hexagonal groove 7 and an air outlet pipe 8 of corresponding size, ensuring that the valve can be stably placed on the first placement plate 5 and tightly connected with the air outlet pipe 8. The design of this convenient disassembly mechanism greatly improves the practicality and flexibility of the device.
