Description

Technical Field

[0001] The present invention relates to the technical field of valves, and specifically to a valve with a built-in sealing auxiliary accessory. Background Art

[0002] A valve is a pipeline accessory used to open and close pipelines, control the flow direction, and adjust and control the parameters (temperature, pressure, and flow rate) of the transported medium. According to its functions, it can be divided into shut-off valves, check valves, regulating valves, etc.;

[0003] In the prior art, when a valve is connected to a pipeline, the valve and the pipeline are fixed together by a screw passing through the ends of the valve and the pipeline;
