Description

Technical Field

[0001] This utility model relates to the field of valve testing, specifically a valve performance testing device that can be quickly clamped and linked. Background Technology

[0002] Valves are widely used in various fluid systems, and their quality has a significant impact on the quality, service life, and maintenance of the fluid system. Therefore, sealing tests must be conducted on valves before they can leave the factory, especially for gate valves, globe valves, and ball valves.

[0003] Existing testing machines are complex in structure, have a high failure rate, and are costly. The clamping of the valve to be tested and the pressure test need to be carried out in separate steps, resulting in low testing efficiency. Utility Model Content

[0029] Valve 39 is pressure tested in water to observe whether there is any leakage in the pressure value of pressure gauge 35.

[0030] After the test, the operator releases the device, which is then reset by the action of the overall tension spring 23, in order to conduct the next test.
