Description

Technical Field

[0001] The utility model relates to the technical field of valve detection, in particular to a pneumatic valve pressure testing machine. Background Art

[0002] Valves are pipe accessories used to open and close pipes, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. Valves have functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief.

[0003] According to the comparison of existing technologies, after the valve is prepared, it is generally necessary to use a valve pressure tester to perform a sealing test on the valve. Usually, the valve needs to be placed on a table, and then air pressure is injected into one end of the valve. At the same time, the table is filled with water so that the water submerges the valve. Then, the quality of the material is tested by observing whether there are bubbles in the water. After the test, the water needs to be drained, thereby wasting a lot of water resources.
