Description

Technical Field

[0001] The utility model relates to the technical field of valve testing, and more specifically, to a portable valve pressure testing device. Background Art

[0002] A portable valve pressure tester is a device specifically designed for on-site testing of valve pressure performance. By applying a certain pressure, it can verify the valve's tightness and pressure-bearing capacity under operating conditions. This is crucial for ensuring the reliability and safety of valves in practical applications.

[0003] Patent publication number CN112504558A discloses a valve pressure tester. This device, equipped with a positioning structure, allows the tester to adapt to testing different valves. Furthermore, the device, equipped with a support plate, a protective door, an observation glass, and fixed and movable magnetic blocks, prevents the user from being injured by flying fragments of valve shattering during testing. This provides enhanced safety and performance. However, this technology still has the following drawbacks.
