Medium-resistant self-tightening sealing element

Abstract

The utility model discloses a medium-resistant self-tightening sealing element, and relates to the technical field of sealing. The medium-resistant self-tightening sealing element comprises a deformable sealing body, a sealing groove formed in the sealing body and an elastic body contained in the sealing groove, the elastic body is provided with two elastic ends, the two elastic ends abut against the groove walls of the two sides of the sealing groove respectively, and the elastic body is further wrapped with a medium-resistant protective layer. According to the self-tightening sealing element, the sealing force of the sealing element can be effectively guaranteed, and impurities on the surface of the elastic body or elements in the elastic body can be prevented from entering a medium.
