Abstract
The utility model relates to a novel sealing ring which comprises a sealing ring body. Two sides of the sealing ring body are respectively provided with a support ring. Protrusions are arranged outside the sealing ring body so that sealing effect is enhanced. The number of the protrusions is two so that an M-shaped double-lip structure is formed. The sealing effect is not influenced when one of the two protrusions is broken. The novel sealing ring has the advantages that the structure is simple, due to adoption of the sealing ring body with the M-shaped double-lip structure, the sealing effect is good, when one of the two protrusions is broken, the sealing effect is not influenced; the sealing ring body adopts a polyurethane material so that wear-resisting property is good and service life is long; bearing capacity of the sealing ring body is increased by the support ring and service life is prolonged.
Description
Technical field
The utility model relates to the seal ring technical field, especially relates to a kind of Novel sealing ring.
Background technique
In the hydraulic transmission process, particularly in the piston seal of reciprocating movement oil cylinder, most of structures are drum-shape sealing ring or hill-shaped seal ring at present.But the sealing effect of cydariform sealing is as one wishes not to the utmost under the operating mode that has.Often occur leaking, affected production work and normally carried out.And the M shape on existing market face circle, there is certain defective in its compound mode, and present product material can't better give play to the performance of product, has reduced the working life of product, has affected normally carrying out of production work.
Therefore, the appearance of the Novel sealing ring of a kind of good seal performance, long service life is necessary.
The model utility content
The utility model is to provide a kind of Novel sealing ring that all can play good seal action under the working pressures such as high pressure or low pressure for solving the problems of the technologies described above, and it has good seal performance, the characteristics such as long service life.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of Novel sealing ring comprises the seal ring body, is respectively arranged with support ring in the both sides of described seal ring body, and the arranged outside of described seal ring body has projection, to strengthen sealing effect.
As preferred technological scheme, described projection is two, to form " M " shape lips structure, in the situation that damaging appears in its any projection, does not affect sealing effect.
As preferred technological scheme, the material of described seal ring body is polyurethane material.
As preferred technological scheme, the cross section of described support ring is " L " shape, to increase the compressive strength of described seal ring body.
As preferred technological scheme, the material of described support ring is polyformaldehyde material.
The beneficial effect that the utlity model has is: (1) is simple in structure, adopts the sealing circle body of " M " shape double-lipped structure, and good sealing effect in the situation that damaging appears in its any projection, does not affect sealing effect;
(2) the sealing circle body adopts polyurethane material, and wear-resisting property is good, long service life;
(3) support ring has increased the bearing capacity of sealing circle body, has prolonged working life.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cross-sectional view of the present utility model;
Wherein: 1-seal ring body, 2-support ring, 3-projection.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Shown in Fig. 1-2, a kind of Novel sealing ring comprises seal ring body 1, is respectively arranged with support ring 2 in the both sides of seal ring body 1.Seal ring body 1 arranged outside has projection 3, and to strengthen sealing effect, the utility model protrusions 3 is two, to form " M " shape lips structure, in the situation that damaging appears in its any projection 3, can also normally use.
The material of seal ring body 1 is polyurethane material, can reduce by 1 wearing and tearing of seal ring body, and the making material that supporting ring 2 adopts is polyformaldehyde material, can play the effect that increases seal ring body 1 intensity.Support ring 2 has adopted L shaped structural type, has increased its supporting surface, and has thickeied wall thickness, makes seal ring can bear larger pressure.
Utilize such material and combinations thereof mode, so that this device can better be brought into play the sealability of itself in the process of using, and long service life.
Above-mentioned material is commercially available material.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (5)
