Description

High-pressure pipeline sealing ring for union

Technical Field

The utility model relates to the field of sealing rings, in particular to a high-pressure pipeline sealing ring for a union.

Background

Unions are also called pipe joints or unions. The pipeline connecting piece is a common pipeline connecting piece which can be conveniently assembled and disassembled. The pipe fitting for connecting the two pipes can separate the two pipes without moving the pipes, thereby being convenient for maintenance. The sealing connection of part union relies on the conical surface of its inside processing, but utilizes the sealed higher packing force that needs of conical surface, and the processing cost is higher simultaneously, and the union that utilizes the sealing washer to carry out sealing connection uses more commonly, and the existing union that utilizes the sealing washer to carry out sealing connection bears the pressure little, can only seal the relative terminal surface of plug bush and sleeve simply, and easy emergence is leaked in the use, can not be applicable to high-pressure pipeline.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is to provide the union high-pressure pipeline sealing ring which has good sealing effect, simple structure and large sealing area and can be suitable for high-pressure pipelines.

In order to achieve the purpose, the technical scheme provided by the utility model is as follows:

the utility model provides a high-pressure line sealing washer is used to union, includes the sealing washer body, has seted up the annular on the right-hand member face of sealing washer body, and processing has outer arc bulge loop on the right-hand member face of sealing washer body, and outer arc bulge loop is located the annular outside, and outer arc bulge loop internal fixation has rather than endocentric outer steel ring, and processing has interior arc bulge loop on the left side cell wall of annular, and interior arc bulge loop internal fixation has rather than endocentric inner steel ring, and this internal fixation of left sealing washer of inner steel ring has the inner ring, inner ring and inner steel ring fixed connection.

Specifically, an inner sleeve is fixed in the sealing ring body on the inner side of the annular groove.

Specifically, the inner sleeve, the ring groove, the outer arc-shaped convex ring, the outer steel ring, the inner arc-shaped convex ring, the inner steel ring, the inner ring and the sealing ring body are arranged concentrically.

Specifically, the width of the inner ring is larger than the groove width of the ring groove.

Compared with the prior art, the utility model has the beneficial effects that:

the utility model has the advantages of simple structure, convenient use, good sealing effect, high structural strength and long service life, and can increase the sealing area and be suitable for high-pressure pipelines.

Detailed Description

As shown in fig. 1-2, a high-pressure pipeline sealing ring for union comprises a sealing ring body 1, a ring groove 2 is arranged on the right end surface of the sealing ring body 1, an inner sleeve 8 is fixed in the sealing ring body 1 at the inner side of the annular groove 2, an outer arc-shaped convex ring 3 is processed on the right end face of the sealing ring body 1, the outer arc-shaped convex ring 3 is positioned at the outer side of the annular groove 2, an outer steel ring 4 concentric with the outer arc-shaped convex ring 3 is fixed in the outer arc-shaped convex ring 3, an inner arc-shaped convex ring 5 is processed on the left groove wall of the annular groove 2, an inner steel ring 6 concentric with the inner arc-shaped convex ring 5 is fixed in the inner arc-shaped convex ring 5, an inner ring 7 is fixed in the sealing ring body 1 at the left side of the inner steel ring 6, the width of inner ring 7 is greater than the groove width of annular 2, inner ring 7 and interior steel ring 6 fixed connection, endotheca 8, annular 2, outer arc bulge loop 3, outer steel ring 4, interior arc bulge loop 5, interior steel ring 6, inner ring 7 and sealing washer body 1 set up with one heart.

When the utility model is used, the sealing ring body 1 is arranged in the sleeve 9, so that the end part of the plug bush 10 and the baffle ring 11 fixed on the plug bush 10 enter the sleeve 9, then the end part of the plug bush 10 is inserted into the annular groove 2 of the sealing ring body 1, so that the plug bush 10 is tightly pressed against the sealing ring body 1, the end part of the plug bush 10 can extrude the inner arc-shaped convex ring 5, the baffle ring 11 can extrude the outer arc-shaped convex ring 3, when the baffle ring 11 extrudes the outer arc-shaped convex ring 3, the outer steel ring 4 moves to the left side and extrudes the sealing ring body 1 part on the left side, under the action of the outer steel ring 4, the sealing ring body 1 part between the plug bush 10 and the sleeve 9 can generate elastic deformation and expansion, the sealing ring body 1 part between the plug bush 10 and the sleeve 9 can seal the outer edge of the plug bush 10 part in the annular groove 2, the inner edge of the sleeve 9 and the end surface of the baffle ring 11, when the end part of the plug bush 10 extrudes the inner arc-shaped convex ring 5, inner steel ring 6 is through inner ring 7 left sealing washer body 1 part of extrusion inner ring 7 to make 1 left end of sealing washer body tightly support sleeve 9, through setting up inner ring 7, can increase the effective sealing area of 1 left end of sealing washer body and sleeve 9, and then improve sealed effect. Through setting up endotheca 8, can increase the structural strength of sealing washer body 1.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
