[0015] Example 1: Please refer to Figure 1-4 An automatic testing platform for the airtightness of high-pressure gas valves includes a mounting platform 7. A circulation pump 2 is installed at the middle position of the bottom of the mounting platform 7, with a circulation suction pipe 1 connected to the input end of the circulation pump 2 and a circulation guide pipe 3 connected to the output end of the circulation pump 2. A water collection tank 14 is installed on one side of the bottom of the mounting platform 7, and a transverse filter plate 16 is installed at the bottom of the water collection tank 14. A suction pump 15 is installed on the other side of the bottom of the mounting platform 7, with a water suction pipe 5 connected to the input end of the suction pump 15 and a water supply pipe connected to the output end of the suction pump 15. The top of the pipe 6 and the mounting platform 7 are both provided with sliding grooves 17. A valve body 10 is provided at the middle position of the top of the mounting platform 7. A water inlet connection pipe 8 is provided on one side of the top of the mounting platform 7. A first mounting plate 9 is installed on the outside of the water inlet connection pipe 8. A water outlet connection pipe 12 is provided on the other side of the top of the mounting platform 7. A drain pipe 13 is connected to one end of the water outlet connection pipe 12. A second mounting plate 11 is installed on the outside of the water outlet connection pipe 12. Slider 18 is installed at both ends of the bottom of the second mounting plate 11 and the first mounting plate 9. The slider 18 is positioned directly above the second mounting plate 11, and the bottom end of the slider 18 passes through the top of the mounting platform 7 and extends into the interior of the groove 17. The inlet pipe 8 and the outlet pipe 12 are respectively located at both ends of the valve body 10, and one end of the inlet pipe 8 and the outlet pipe 12 are connected to both ends of the valve body 10 through flanges. One end of the water supply pipe 6 passes through one end of the water inlet connection pipe 8 and is connected to the water inlet connection pipe 8. The water supply pipe 6 is connected to the valve body 10 through the water inlet connection pipe 8. One end of the pumping pipe 5 passes through the bottom of one side of the water storage tank 4 and extends into the interior of the water storage tank 4, and one end of the circulation guide pipe 3 passes through the mounting platform 7 and one side of the water storage tank 4 in sequence and extends into the upper part of the interior of the water storage tank 4. One end of the circulating suction pipe 1 passes through the mounting platform 7 and the water collection tank 14 and extends to the bottom of the inside of the water collection tank 14, and one end of the drain pipe 13 passes through the top of the water collection tank 14 and extends to the inside of the water collection tank 14. The drain pipe 13 and the circulating suction pipe 1 are respectively installed on both sides of the transverse filter plate 16, and the outer side of the transverse filter plate 16 is in contact with the inner wall of the water collection tank 14. Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, during the use of this device, the valve body 10, whose airtightness needs to be tested, can be placed in the middle position above the mounting platform 7. Then, by utilizing the presence of the inlet connecting pipe 8 and the outlet connecting pipe 12, and the sliding structure of the slide groove 17 and the slider 18, the horizontal position of the first mounting plate 9 and the second mounting plate 11 can be flexibly adjusted. This allows the inlet connecting pipe 8 and the outlet connecting pipe 12 to move flexibly, ensuring that the inlet connecting pipe 8 and the outlet connecting pipe 12 are connected to both ends of the valve body 10. Then, this device... The device can be activated by turning on the suction pump 15. Driven by the suction pump 15, water inside the water storage tank 4 is drawn and transported to the inlet connection pipe 8 under the guidance of the suction pipe 5 and the delivery pipe 6. When testing the airtightness of the valve body 10, the device can first close the valve body 10. After the suction pump 15 drives water to the valve body 10 through the inlet connection pipe 8, the airtightness of the valve body 10 can be determined by observing whether water is discharged from the outlet of the drain pipe 13. When water is discharged from the outlet of drain pipe 13, it proves that the airtightness of valve body 10 is poor; otherwise, valve body 10 has good airtightness. Then, the device can gradually open valve body 10, allowing drain pipe 13 to drain. By observing the water discharge efficiency of drain pipe 13, the control quality of valve body 10 can be obtained. Finally, after the test is completed, the device is equipped with a circulation pump 2. By turning on the circulation pump 2, the test water inside the water collection tank 14 can be sucked out and returned to the water storage tank 4 under the guidance of circulation suction pipe 1 and circulation guide pipe 3, thus achieving a water circulation effect, effectively reducing the test cost, facilitating continuous testing, and having high efficiency. Secondly, by setting a transverse filter plate 16 inside the water collection tank 14, the test water inside the water collection tank 14 can be automatically filtered and purified during the suction process of circulation pump 2, avoiding impurities from entering during the test process and causing damage to valve body 10, thus ensuring the test quality of the device and making it quite practical.
