Description

Technical Field

[0001] The utility model relates to the technical field of sealing rings, in particular to an energy-storage self-compensating sealing ring. Background Art

[0002] A spring-energized seal is a high-performance sealing element that combines the elastic force of a spring with the properties of the sealing material to adapt to a variety of complex working conditions. This seal consists primarily of a seal body, a sealing lip, and a spring. The seal body is typically made of high-performance polymers such as PTFE, filled PTFE, and PEEK, which offer excellent chemical stability and a low coefficient of friction. The spring provides continuous radial pressure, ensuring close contact between the sealing lip and the sealing surface, thereby achieving an effective seal.

[0003] At present, most energy-storage self-compensating sealing rings clamp the energy-storage spring in the groove of the sealing ring. After a period of use, a large amount of dust or oil will gradually adhere to the groove, which will have a certain impact on the elasticity of the energy-storage spring. Moreover, if used in the food industry, it will soon fail to meet the hygiene requirements after a period of use. Therefore, an energy-storage self-compensating sealing ring is proposed.
