Description

Technical Field

[0001] The utility model relates to the technical field of valve sealing performance detection, in particular to a gas valve sealing performance detection device. Background Technique

[0002] Gas is the general term for gaseous fuels, which can burn and release heat for use by residents and industrial enterprises. There are many types of gas, mainly including natural gas, artificial gas, liquefied petroleum gas, biogas, and coal gas. Gas valves are the main components on gas transmission pipelines, used to control the on-off of pipelines. After the sealing performance of gas valves decreases, gas leakage will occur. Therefore, it is necessary to detect the sealing performance of gas valves. If gas is detected at the gas valve, it indicates that there is a problem with the sealing performance of the gas valve.
