Description

Technical Field

[0001] The utility model relates to the field of rubber sealing components, in particular to a novel rubber sealing component structure. Background Art

[0002] Rubber seals are a type of universal basic component in sealing devices, playing a very important role in the contradiction between leakage and sealing. They solve leakage and sealing problems in the process of human conquering nature. They have always been an important way to promote technological progress, prevent and reduce environmental pollution. Rubber seals are a type of rubber product widely used in sealing technology. Because rubber is a valuable elastic polymer material with a wide temperature range, it will produce a large deformation when given a small stress in different media. This deformation can provide contact pressure, compensate for leakage gaps, and achieve the purpose of sealing. Rubber seals are materials or parts that prevent fluids or solid particles from leaking from adjacent joint surfaces and prevent external impurities such as dust and moisture from invading parts inside machinery and equipment. The storage room temperature of seals is best below 30°C to avoid high temperature aging of seals.

[0003] Rubber seals are made of natural rubber or synthetic rubber and have a certain elasticity. After being squeezed for a long time, they will produce a certain deformation and it is difficult to restore to the original shape, resulting in a decrease in the sealing performance of the rubber seals.

[0004] Therefore, we made improvements to this and proposed a new rubber seal structure. Utility Model Content
