Description

Technical Field

[0001] The present invention relates to the technical field of sealing components, and in particular to a sealing component for a valve. Background Art

[0002] Seals are materials or parts that prevent fluids or solid particles from leaking between adjacent joint surfaces and prevent external impurities such as dust and moisture from invading components inside machinery and equipment. Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. The most commonly used seals in valves are gaskets. When installing the valve on the pipeline, by adding gaskets, no leakage will occur when the valve is connected to the pipeline.

[0003] Valves and pipes are often installed outdoors. When installed outdoors, due to the complex natural environment, gaskets made of metal, rubber or other materials will be corroded by the natural environment. At the same time, valve gaskets, as important sealing components of valves, will be affected by factors such as pressure, temperature, and vibration during long-term use, and are prone to wear, aging, and cracking. In order to maintain their normal sealing performance, reduce friction, and extend their service life, lubricating oil is usually added to both sides of the gasket. The lubricating oil not only lubricates, but also improves the sealing performance and avoids leakage. However, there are many valves in the pipeline, the installation environment is complex, and they cannot be disassembled at will. Therefore, in many cases, the gaskets cannot be lubricated, which makes the gaskets easily damaged due to long-term lack of lubrication. Summary of the invention
