[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. A valve is a control component in a fluid transportation system, with functions such as cut-off, regulation, diversion, prevention of backflow, pressure stabilization, flow division, or overflow pressure relief. Valves used in fluid control systems range from the simplest stop valves to various valves used in extremely complex automatic control systems, with a wide variety of types and specifications. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metals, and radioactive media.

[0003] However, in the prior art, the silicone flat gasket seals used between valves and flanges may swell when coming into contact with some special chemical liquids such as gasoline and refined oil under special circumstances. After swelling, the silicone material of the gasket will soften, and at this time, the gasket is likely to fall off, resulting in leakage accidents of the valve due to the falling off of the gasket.
