Description

Technical Field

[0001] The utility model relates to the field of pressure-resistant rubber sealing rings, in particular to a pressure-resistant rubber sealing ring. Background Art

[0002] O-type rubber sealing rings are widely used in sealing of internal combustion locomotives, automobiles, tractors, construction machinery, machine tools and various hydraulic and pneumatic components. They can undertake the sealing of fixed, reciprocating and rotating motions. O-type rubber sealing rings account for more than 50% of the sealing of mechanical products. According to needs, various special-purpose sealing rings and special-shaped rubber sealing products for high temperature resistance, low temperature vacuum, high pressure and different media can be produced.

[0003] The existing O-ring cannot bear a sufficiently large pressure resistance, and when it can bear a sufficient pressure resistance, it deforms, resulting in a decrease in sealing performance. Therefore, a pressure-resistant rubber sealing ring is urgently needed. Utility Model Content
