Abstract

The utility model discloses a seal ring with double seal lips. The seal ring comprises a seal ring body. A first seal lip is arranged on the outer circumference surface of the seal ring body, a second seal lip is formed on the outer circumference surface of the seal ring body, and an oil storage device is arranged between the first seal lip and the second seal lip. For the seal ring with the double seal lips, the structure is simple, and the cost is low; in addition, the two seal lips are arranged on the outer circumference surface of the seal ring body, an oil storage groove is arranged between the two seal lips so that when the seal ring is used, lubricating oil can be stored in the groove to lubricate the seal ring, therefore, the service life of the seal ring can be prolonged.

Description

A kind of seal ring with double-sealing lip
Technical field:
The utility model relates to technical field of hydraulic elements, relates to a kind of seal ring that is used for the hydraulically-controlled one-way valve sealing in particular.
