Novel composite rubber sealing ring

Abstract

The utility model discloses a novel composite rubber sealing ring which comprises a sealing ring body, a steel spring and a through hole. The sealing ring is in a lip shape, a lip opening is obliquely arranged, an embedded steel spring is arranged in the sealing ring, and a round through hole is formed between the interior of the lip opening and the bottom face. Compared with the prior art, the lip-type sealing structure is good in sealing performance, high in pressure bearing performance, soft, large in elongation, high in strength, long in product service life and capable of greatly improving safety.

Description

TECHNICAL FIELD

[0001] The utility model relates to sealing ring technical field, concretely is a new type composite rubber sealing ring. BACKGROUND

[0002] Natural gas mixed gas transportation pipeline valve usually installs rubber sealing ring, plays pressure -resistant, sealed and corrosion -resistant effect. Common product structure adopts rectangular structure, does not have built -in steel spring, and sealing effect and pressure bearing are not good, and corrosion resistance is poor, and product service life reaches the requirement, and product is damaged in less than 2 years. SUMMARY

[0003] In view of the problems existing in the prior art, the utility model discloses a new type composite rubber sealing ring, including sealing ring, steel spring, through -hole, the sealing ring is lip -shaped, and the lip mouth is inclined to set, and the inside is equipped with the built -in steel spring, and the circular through -hole is equipped between the lip mouth and the bottom surface,

[0004] As a preferred technical scheme of the utility model, the steel spring material is 304 stainless steel.

[0005] The utility model has the advantages of lip type sealing structure, good sealing, improved pressure bearing, softness, high elongation, high strength, long product life and greatly improved safety. BRIEF DESCRIPTION OF DRAWINGS

[0006] In order to more clearly illustrate the specific embodiment of the utility model or the technical scheme in the prior art, the following will briefly introduce the drawing needed to be used in the specific embodiment or prior art description. In all drawings, various elements or parts are not necessarily drawn according to actual proportion.

[0007] Fig. 1 It is the three-dimensional schematic diagram of the utility model;

[0008] Fig. 2 It is the sectional view of the utility model;

[0009] In the drawing: sealing ring 1, steel spring 2, through -hole 3. DETAILED DESCRIPTION

[0010] Example 1

[0011] As Figs. 1-2 The utility model discloses a new type composite rubber sealing ring, including sealing ring 1, steel spring 2, through -hole 3, the sealing ring 1 is lip -shaped, and the lip mouth is inclined to set, and the inside is equipped with the built -in steel spring 2, and the circular through -hole is equipped between the lip mouth and the bottom surface. Steel spring 2 material is 304 stainless steel. The overall sealing performance is good, and the pressure bearing is improved, and it is soft, and the elongation is big, and the strength is high, and the product life is long, and the safety is greatly improved.

[0012] Components not described in detail herein are of the prior art.

[0013] Although the specific embodiments of the present application are described in detail above, the present application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present application, and modifications or transformations without creative labor are still within the protection scope of the present application.
