[0002] Gas is a general term for gaseous fuels. Gas fuels can release heat through combustion and are used by residential and commercial users. When connecting gas pipelines, they are usually used in conjunction with gas safety valves. Gas safety valves usually refer to safety devices used in gas pipeline systems. Their function is to monitor the gas pressure in the pipeline system and take measures to ensure the safety of the system and users when abnormal conditions are detected. These valves are usually designed to operate automatically and can automatically close or open when necessary to prevent gas leaks or other dangerous situations.

[0003] At present, when using the gas safety valve on the market, the filter screen is generally directly installed on the air inlet end of the gas safety valve through the locking piece. The existing gas safety valve can only be installed by installing tools when installing the filter screen, which makes the installation more complicated. Therefore, we propose a gas safety valve that is easy to install. Utility Model Content
