Description

Rubber sealing ring

Technical Field

The utility model belongs to the technical field of the sealing washer, a rubber seal is related to.

Background

Pipe-line system is in the heat supply, supply water, the air feed field has very wide application, pipe-line system is formed by many root canal coupling, the fastening nature of connecting between the pipeline will directly influence the life of whole pipe-line system normal operating, in order to strengthen the fastening nature of connecting between the management, can set up the sealing washer of circle annular structure in the junction between the pipeline usually among the prior art, under long-term rheological carrier pressure, the deflection of sealing washer is crescent, and along with the lapse of time, can lead to elasticity and the resilience of sealing washer, performance such as mechanical strength is not enough to satisfy the operation requirement, make the leakproofness of pipe-line junction reduce, and then cause phenomenons such as pipe-line system infiltration and leak easily.

Disclosure of Invention

The utility model aims at solving the problems of the prior art and providing a rubber sealing ring. The utility model provides a technical problem be how to improve rubber seal's anti deformability and seal the effect with the reinforcing.

The purpose of the utility model can be realized by the following technical proposal:

the utility model provides a rubber seal, includes the sealing washer body, its characterized in that, the inside of sealing washer body is inlayed and is cyclic annular and hollow supporting framework, and supporting framework's vertical cross-section is the V type, supporting framework's top or middle part are provided with a plurality of strengthening ribs along circumference, and a plurality of strengthening ribs set up along the horizontal direction.

The vertical section of the supporting framework of the rubber sealing ring is V-shaped, so that the supporting range of the supporting framework in the sealing ring body is larger, the anti-deformation capacity of the rubber sealing ring is improved, meanwhile, the supporting framework is annular and the inside of the supporting framework is hollow, on one hand, the weight of the supporting framework can be reduced, on the other hand, the supporting framework is embedded in the sealing ring body, the sealing ring body is also filled in the hollow part of the supporting framework, so that the resistance capacity of the rubber sealing ring to external force impact is further enhanced, the anti-deformation capacity of the rubber sealing ring is further improved, in addition, a plurality of reinforcing ribs are arranged at the top or/and the middle part of the supporting framework along the circumferential direction, a plurality of reinforcing ribs are arranged along the horizontal direction, a plurality of reinforcing ribs form a triangular structure with the supporting framework respectively, the advantage of good triangular stability is fully utilized, and the deformation of the rubber sealing ring after being stressed is further reduced, thereby further improve rubber seal's anti deformability, so this rubber seal can improve rubber seal's anti deformability in order to strengthen sealed effect.

In the above rubber seal ring, the top and the middle part of the supporting framework are both uniformly provided with a plurality of reinforcing ribs along the circumferential direction, and the plurality of reinforcing ribs are arranged in a staggered manner from top to bottom.

A plurality of strengthening ribs form the triangle-shaped structure with supporting framework respectively, and above-mentioned structure makes the triangle-shaped structure along circumference evenly distributed, and dislocation distribution from top to bottom, make full use of the good advantage of triangle-shaped stability, further reduced the deflection after the rubber seal atress to further improve rubber seal's anti deformability.

In the above one rubber packing, the supporting frame is made of metal. The supporting framework is made of metal, so that the rigidity of the supporting framework can be further enhanced, and the deformation resistance of the rubber sealing ring is further improved.

In the above rubber seal ring, the seal ring body is of an integrally formed structure. The sealing ring body is of an integrally formed structure, so that the rigidity of the sealing ring body can be further enhanced, and the deformation resistance of the rubber sealing ring is further improved.

In the above rubber seal ring, a radial width of the seal ring body is large at the top and small at the bottom. The radial width of sealing washer body is big-end-up, is the structural shape looks adaptation of V type with the support chassis to further improve rubber seal's anti deformability.

Compared with the prior art, the rubber sealing ring has the advantages that: the vertical section of the supporting framework of the rubber sealing ring is V-shaped, so that the supporting range of the supporting framework in the sealing ring body is larger, meanwhile, the supporting framework is annular and the inside of the supporting framework is hollow, on one hand, the weight of the supporting framework can be reduced, on the other hand, the supporting framework is embedded in the sealing ring body, so that the sealing ring body is also filled in the hollow part of the supporting framework, the resistance capability of the rubber sealing ring to external force impact is further enhanced, in addition, a plurality of reinforcing ribs are arranged on the top part or/and the middle part of the supporting framework along the circumferential direction and are arranged along the horizontal direction, and the plurality of reinforcing ribs respectively form a triangular structure with the supporting framework, so that the advantage of good triangular stability is fully utilized, the deformation of the rubber sealing ring after being stressed is further reduced, and the anti-deformation capability of the rubber sealing ring is further improved, therefore, the rubber sealing ring can improve the deformation resistance of the rubber sealing ring so as to enhance the sealing effect.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

The utility model provides a rubber seal, refers to fig. 1-4, includes sealing washer body 1, and the inside of sealing washer body 1 is inlayed and is equipped with and be cyclic annular and hollow supporting framework 2, and supporting framework 2's vertical cross-section is the V type, supporting framework 2's top or/and middle part are provided with a plurality of strengthening ribs 3 along circumference, and a plurality of strengthening ribs 3 set up along the horizontal direction. In the implementation, preferably, a plurality of reinforcing ribs 3 are uniformly arranged on the top and the middle of the supporting framework 2 along the circumferential direction, and the plurality of reinforcing ribs 3 are arranged in a vertically staggered manner; preferably, the support frame 2 is made of metal.
