Abstract

The utility model discloses a sealing ring with grooves. The upper surface of the sealing ring is provided with an internal sealing lip, an external sealing lip and a sealing circle positioned between the internal sealing lip and the external sealing lip, an external annular groove is arranged on the external circumferential surface of the sealing ring, and an internal annular groove is arranged on the internal circumferential surface of the sealing ring. The sealing ring is simple in structure and low in price. Since the annular grooves are arranged on the upper surface, the lower surface, the internal surface and the external surface respectively, lubricating oil can be stored in the grooves when the sealing ring is used and can have a role in lubricating the sealing ring. Moreover, sealing effect of the sealing ring can be enhanced and the service life of the sealing ring can be prolonged.

Description

A kind of seal ring that has groove
Technical field:
The utility model relates to technical field of hydraulic elements, relates to a kind of seal ring that is used for the sealing of hydraulic pressure components and parts 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 that has groove, the upper surface of described seal ring have an interior seal lip, external sealed lip; The upper surface of described seal ring also has a sealed circular ring between described inside and outside seal lip.
Described a kind of seal ring that has groove, the lower surface of described seal ring has an interior seal lip, external sealed lip; The lower surface of described seal ring also has a sealed circular ring between described inside and outside seal lip.
Described a kind of seal ring that has groove, the outer peripheral surface of described seal ring has an outer ring groove.
Described a kind of seal ring that has groove, the inner peripheral surface of described seal ring has an interior annular groove.
The utility model beneficial effect is:
This novel ring structure is simple, cheap, because an annular groove is all arranged on the inside and outside surface of seal ring, make and in groove, to store lubricant oil when in use, play lubricated effect for seal ring, prolong the working life of seal ring, and all there are inside and outside seal lip and sealed circular ring in upper and lower surface, can the enhanced leaktightness effect.
