Abstract

The invention discloses a sealing ring. The sealing ring comprises a sealing ring body, wherein the sealing ring body is made of natural rubber or synthetic rubber, an annular elastic body is arranged in the sealing ring body, and the annular elastic body is a toroidal elastic body. The annular elastic body is arranged in the sealing ring body of the sealing ring; the elasticity of the sealing ring can be increased due to the annular elastic body, and the sealing ring body can be prevented from being extruded and damaged; meanwhile, the cross section of the annular elastic body is in the shape of a plum blossom, and the stability of combination between the annular elastic body and the sealing ring body can be increased. The sealing ring is good in elasticity, long in service life and good in sealing performance.

Description

A kind of seal ring
Technical field
The present invention relates to a kind of improvement of seal arrangement, particularly a kind of good springiness, the life-span is long, sealability is good seal ring.
Background technique
Common seal ring, generally adopts natural rubber or synthetic rubber to make.There is following problem in this seal ring: natural rubber or synthetic rubber are sharply aging under high temperature and high pressure environment and under chemical mediator, cause life cycle short, generally only have 2 years less than 1 year even; Simultaneously common seal ring generally just adopts a kind of material to make, good springiness or corrosion resistance is strong, and the life-span is long, and the two can only select one, and for this reason, we have researched and developed a kind of good springiness, the life-span is long, sealability is good seal ring.
Summary of the invention
Technical problem for above-mentioned existence, the object of the invention is: proposed a kind of good springiness, the life-span is long, sealability is good seal ring.
Technical solution of the present invention is achieved in that a kind of seal ring, comprises seal ring body; Described seal ring body is made by natural rubber or synthetic rubber; In described seal ring body, be provided with annular elastomeric.
Preferably, described annular elastomeric is ring elastomer.
Preferably, the cross section of described annular elastomeric is plum blossom-shaped.
Preferably, described annular elastomeric is made by teflon.
Preferably, described annular elastomeric is made by PVC.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
In seal ring body in seal ring of the present invention, be provided with annular elastomeric; Described annular elastomeric can increase the elasticity of seal ring, can prevent that seal ring body is squeezed and damages; The cross section of described annular elastomeric is plum blossom-shaped simultaneously, can increase the combination stability of annular elastomeric and seal ring body; Good springiness of the present invention, the life-span is long, sealability is good.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
The plan view that accompanying drawing 1 is seal ring of the present invention;
Accompanying drawing 2 is the A-A sectional view of accompanying drawing 1;
Wherein: 1, seal ring main body; 2, annular elastomeric.
embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Of the present invention a kind of seal ring as shown in accompanying drawing 1-2, comprises seal ring body 1; Described seal ring body 1 is made by natural rubber or synthetic rubber; In described seal ring body 1, be provided with annular elastomeric 2; Described annular elastomeric 2 is ring elastomer; Described annular elastomeric 2 is made by teflon.
Certainly, described annular elastomeric 2 also can be made by PVC.
Certainly, the cross section of described annular elastomeric 2 can be also plum blossom-shaped.
In seal ring body 1 in seal ring of the present invention, be provided with annular elastomeric 2; Described annular elastomeric 2 can increase the elasticity of seal ring, can prevent that seal ring body 1 is squeezed and damages; The cross section of described annular elastomeric 2 is plum blossom-shaped simultaneously, can increase the combination stability of annular elastomeric 2 and seal ring body 1; Good springiness of the present invention, the life-span is long, sealability is good.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
