High-pressure automatic air suction valve

The utility model belongs to the field of air suction valves, and particularly relates to a high-pressure automatic air suction valve which comprises a valve body assembly, a valve element assembly and a reset assembly. The valve body assembly comprises an air suction valve body and an air suction valve seat. The air suction valve body is installed on the top of the air suction valve seat. When the internal pressure of the valve element assembly is larger than the external pressure, the valve element assembly makes close contact with the limiting hole, the air suction valve is in a sealed state at the moment, and media in a high-pressure container and a high-pressure pipeline cannot leak outwards due to the pressure; when a medium in a container is sucked and emptied or a medium in a pipeline is sprayed and emptied, vacuum or negative pressure can be generated in the closed interior, the internal pressure of the valve element assembly is smaller than the external pressure, the external atmospheric pressure qu
