Description

Technical Field

[0001] The utility model relates to the technical field of pipe valve leakage detection, in particular to a pipe valve leakage detection device which is easy to use. Background Art

[0002] Valves are usually devices used to control the direction, pressure, and flow of fluids. The media inside them are mainly liquids, gases, or powders. Especially in important industries such as chemical industry and natural gas, the requirements for valve body installation are very strict, and leakage is not allowed. This requires that the valve body be leak tested after production to prevent unqualified products from entering the market. In order to ensure that the leakage detection of the valve body meets the factory requirements, the valve body needs to be leak tested to improve the quality of the valve body leak detection.

[0003] The pipe valve leak detection device described in Publication No. CN216869939U utilizes a first connector to be plugged into the air inlet of the pipe valve to be detected and a second connector to be plugged into the air outlet of the pipe valve to be detected, so that the pipe valve leak detection device and the pipe valve to be detected form a complete gas passage. After the gas source is supplied, whether the pipe valve to be detected is leaking is determined based on the measurement data of the first pressure gauge and the second pressure gauge. If the measurement data of the first pressure gauge and the measurement data of the second pressure gauge are the same, the pipe valve to be detected is not leaking. If the measurement data of the first pressure gauge and the measurement data of the second pressure gauge are different, the pipe valve to be detected is leaking. The static clamping member and the dynamic clamping member cooperate to clamp the pipe valve to be detected, so as to ensure the air tightness of the plug-in connection between the first connector and the air inlet of the pipe valve to be detected and the air tightness of the plug-in connection between the second connector and the air outlet of the pipe valve to be detected, thereby improving the accuracy of detection. However, the prior art still has defects:

[0004] 1. The prior art requires one hand to hold the pipe valve and the other hand to manually press the pressing handle to push the clamping frame to clamp the pipe valve, and continuous pressing is required to maintain the clamping state, which is time-consuming, labor-intensive and inconvenient to use.

[0005] 2. After the pipe valve is clamped in the prior art, although the pressure gauge can be used to measure whether the pipe valve is leaking, it is impossible to flip or rotate it for observation, making it difficult for workers to find the leak. Utility Model Content
