Abstract

A pipeline socket seal ring belongs to pipeline connecting devices, is an annular rubber ring, and is characterized in that the annular rubber ring comprises an outer ring and an inner ring, one side of the inner ring is integrally connected with the outer ring, the inner ring is a conical ring naturally, the outer ring is provided with a circle of rib, and the rib is disposed at the connection position of the inner ring with the outer ring. The inner ring is a cylindrical ring when being used, the outer ring is joined with a cast iron pipe socket, after the cast iron pipe socket is inserted into the inner ring, the inner ring deforms and compresses the outer ring, and thereby the sealing effect is achieved by the aid of rubber deformation. The pipeline socket seal ring is higher in shock resistance, simple in maintenance operation and easy in replacement.

Description

Pipeline interface seal ring

Technical field:

The utility model belongs to assembling pipe joint, is specifically related to pipeline interface seal ring.

Background technique:

At present, the general cement grouting that adopts of pipeline interface sealing, its poor seismic behavior, working life is shorter, during interface generation seepage, complicated and difficult replacing of maintenance operation.

Summary of the invention:

The utility model provides a kind of pipeline interface seal ring that flexibly connects.

The utility model is an annular rubber ring, it is characterized in that: annular rubber ring is made of outer ring and inner ring, and the limit and the outer ring of inner ring connect as one, and inner ring is taper ring under nature, the outer ring is provided with a circle fin, and fin is arranged on the link position place of inner ring and outer ring.

Inner ring of the present utility model is cylindrical ring under user mode, and the outer ring engages with cast iron pipe bellmouth, after the cast iron tube socket inserts inner ring, makes inner ring distortion and compression outer ring, reaches sealing effect by rubber deformation.

The utility model anti-seismic performance is higher, the simple and replacing easily of maintenance operation.
