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
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.
Background technique:
In various hydraulic systems, hydraulic pressure components and parts, the hydraulic seal circle hydraulic services that is absolutely necessary, seal ring is divided into static seal and reciprocating movement sealing, is used for preventing hydraulic oil or oil seepage, the proper functioning of assurance system or components and parts.But existing ring structure complexity, sealing effect is bad, the life-span is short, installs inconvenient.
The model utility content:
The purpose of this utility model is at the deficiencies in the prior art part, and a kind of seal ring of simple in structure, good sealing effect is provided.
Technology solution of the present utility model is as follows:
A kind of seal ring with double-sealing lip comprises the seal ring body, at the outer peripheral surface of described seal ring body first seal lip is arranged.
Described a kind of seal ring with double-sealing lip, the outer peripheral surface of described seal ring body forms second lip of seal, between described first seal lip and the described second lip of seal Fuel Tanking Unit is arranged.
Described a kind of seal ring with double-sealing lip, described oil-bearing structure is the annular groove that extends along described seal ring body outer peripheral surface.
The utility model beneficial effect is:
This novel ring structure is simple, cheap, two seal lips are arranged on the outer peripheral surface of seal ring body, and between two seal lip, also has oil storage grooves, make and in groove, to store lubricant oil when in use, play lubricated effect for seal ring, can prolong the working life of seal ring, and because it is that two seal lips are arranged, can the enhanced leaktightness effect.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model.
