[0022] As a technical optimization of this utility model, an air pipe 8 is connected between the air compressor 2 and the air tank 3, and a solenoid valve 9 is fixedly installed on the outside of the air pipe 8.

[0023] In this embodiment: by setting up a solenoid valve 9, it is easy to control the solenoid valve 9 to open and pressurize the air tank 3 through the air compressor 2 and the air pipe 8.

[0024] As a technical optimization of this utility model, a pressure display screen 11 for displaying values ​​is fixedly installed on the top of the gas storage tank 3, and a pressure sensor 10 is provided at the bottom of the pressure display screen 11 and the pressure sensor 10 is located inside the gas storage tank 3.

[0025] In this embodiment: by setting up a pressure display screen 11, the pressure in the air tank 3 can be detected by the pressure sensor 10 and the pressure value can be displayed on the pressure display screen 11, so that the tester can observe the changes in the value displayed on the pressure display screen 11 to determine whether the bypass valve assembly 18 under test is leaking.

[0026] As a technical optimization of this utility model, a connecting pipe is fixedly installed between the gas storage tank 3 and the test tank 5. The gas storage tank 3 passes through the left side of the test tank 5 through the connecting pipe and is connected to the test seat 12. An electric telescopic rod 7 is fixedly installed on the right side of the test tank 5. A top seat 17 corresponding to the position of the test seat 12 is installed at the output end of the electric telescopic rod 7.

[0027] In this embodiment: by setting up an electric telescopic rod 7 and a top seat 17, it is convenient to use the electric telescopic rod 7 to drive the top seat 17 to clamp the bypass valve assembly 18 to be tested between the test seat 12 and the top seat 17, so as to fix and clamp the bypass valve assembly 18 to be tested, and facilitate the tester to disassemble and assemble the bypass valve assembly 18 to be tested.

[0028] As a technical optimization of this utility model, the bypass valve assembly 18 to be tested is clamped between the test seat 12 and the top seat 17, and a sealing gasket is provided on the opposite side of the test seat 12 and the top seat 17.

[0029] In this embodiment, the sealing gasket provided between the test seat 12 and the top seat 17 can clamp and seal the bypass valve assembly 18 under test, and also protect the bypass valve assembly 18 under test.

[0032] Working principle: In use, the electric telescopic rod 7 first drives the top seat 17 to move, clamping and fixing the bypass valve assembly 18 to be tested between the test seat 12 and the top seat 17. Then, the air compressor 2 is started to control the solenoid valve 9 to open and fill the air tank 3 with air through the air pipe 8. After pressurization, the air pressure detected by the air pressure sensor 10 is transmitted to the air pressure display screen 11 to display the air pressure value. Then, by observing whether the value on the air pressure display screen 11 changes, it is determined whether the bypass valve assembly 18 under test is leaking. When the value on the air pressure display screen 11 does not change, it indicates that the bypass valve assembly 18 is leaking. The bypass valve assembly 18 under test is performing well. When the value on the air pressure display screen 11 changes, the water in the water tank 4 is pumped into the test tank 5 by starting the submersible pump 13. The water discharged through the water outlet 14 covers the top of the bypass valve assembly 18 under test. The tester observes the position of the bubbles in the water to determine whether there is a leak in the bypass valve assembly 18 under test. If the bubbles appear at the connection between the bypass valve assembly 18 under test and the test seat 12, the bypass valve assembly 18 under test is repositioned and a second test is performed to improve the accuracy of the test.
