The invention discloses a double-hardness sealing ring which comprises a first circular sealing body and a second circular sealing body, wherein the first circular sealing body comprises a first circular base and a first circular sealing lip bulges from the axial end surface of the first base along the axial direction; the second circular sealing body comprises a second circular base and a second circular sealing lip bulges from the axial end surface of the second base along the axial direction; the first sealing lip and the second sealing lip are arranged on the same side and spaced by a certain distance; the first sealing body and the second sealing body differ in hardness. The double-hardness sealing ring provided by the invention has the benefits that when elastic bodies with different hardness need to be adopted for hermetically sealing various sealing surfaces with different hardness demands, the requirement can be met while the sealing effect is further improved.
Description
technical field [0001] The invention relates to a sealing ring, in particular to a double-hardness sealing ring. Background technique [0002] Generally speaking, the sealing ring needs to meet the following technical conditions: full of elasticity and resilience; with appropriate mechanical strength, including expansion strength, elongation and tear strength, etc.; stable performance, not easy to swell in the medium, thermal shrinkage The effect (Joule effect) is small; it is easy to process and form, and can maintain precise dimensions; it does not corrode the contact surface, and does not pollute the medium. [0003] The sealing rings in the prior art have the following disadvantages: most of the sealing rings are only made of elastomer materials with a single hardness. The sealing ring cannot meet the demand; the sealing effect of a single hardness sealing ring is poor and cannot achieve the required sealing effect. SUMMARY OF THE INVENTION [0004] In view of the de...
