Description
Technical Field
The utility model relates to a rubber seal field especially relates to a rubber lip circle of stand wear and tear high elasticity.
Background
The lip-shaped sealing ring is sealed by deforming the lip under the action of hydraulic pressure to make the lip tightly contact with the sealing surface. The higher the hydraulic pressure is, the tighter the lip edge is attached to the sealing surface, and the lip edge has certain automatic compensation capability after being worn. Such seals are commonly used for reciprocating dynamic seals.
Through retrieval, chinese patent discloses an angular lip-shaped rubber sealing ring (publication No. CN 103994228A), which has good elasticity but does not have the problem of good wear resistance, thereby resulting in short service life and requiring frequent replacement, and therefore, a person skilled in the art provides a wear-resistant high-elasticity rubber lip-shaped ring to solve the problems proposed in the background art.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the shortcoming that exists among the prior art, and the rubber lip circle of a stand wear and tear high elasticity that proposes provides an outer lane wear-resisting, and the inner circle has high elasticity, long service life, the rubber lip circle that the operating mode is good.
In order to achieve the above purpose, the utility model provides a following technical scheme:
a wear-resistant high-elasticity rubber lip-shaped ring comprises an inner ring, wherein an inner lip is fixedly connected to the outer side of the inner ring, an outer lip is arranged at the lower end of the inner lip in an embedded mode, and a rubber ring is arranged inside the outer lip;
through the technical scheme, the lip-shaped sealing ring is good in wear resistance, high in elasticity and long in service life.
Furthermore, a first annular clamping groove is formed in one side, close to the inner ring, of the inner lip, a first annular protrusion is formed in one side, close to the inner ring, of the outer lip, and the first annular clamping groove and the first annular protrusion are nested together;
through above-mentioned technical scheme, provide the stability of lip-shaped circle.
Furthermore, a second annular clamping groove is formed in one side, away from the inner ring, of the inner lip, a second annular bulge is formed in one side, away from the inner ring, of the inner lip, and the second annular clamping groove and the second annular bulge are nested together;
through above-mentioned technical scheme, provide the stability of lip-shaped circle.
Furthermore, the outer lip and the inner lip are made of nitrile rubber;
according to the technical scheme, the nitrile rubber is a polymer formed by copolymerizing butadiene and acrylonitrile through emulsion, and has good wear resistance, aging resistance and air tightness.
Furthermore, the rubber ring and the inner ring are made of butadiene rubber;
through the technical scheme, the butadiene rubber is prepared by solution polymerization of butadiene, and the butadiene rubber has particularly excellent cold resistance, wear resistance and elasticity and also has better aging resistance.
The utility model discloses following beneficial effect has:
1. the utility model discloses in, set up the nested mode of interior outer lip, interior outer lip can effectively improve the wearability of lip circle.
2. The utility model discloses in, set up the rubber circle in inside, inside rubber circle can provide elasticity, also can follow different work condition and change.
