Abstract

The utility model discloses a sealing rubber gasket for a pipe repair section. The sealing rubber gasket comprises a rubber gasket consistent with the edge of the pipe repair section. The sealing rubber gasket is characterized in that the rubber gasket has edges on both sides; mounting holes are formed on the edges; and one or more chutes facing inwards are respectively formed in front of and behind the semi-circular inner wall of the rubber gasket. Compared with the prior art, the sealing rubber gasket has the advantages that three sealing chutes are formed at both arc ends of the rubber gasket for protecting the gasket when the clasping the pipe wall; and a fixing ring is arranged on both sides of the rubber gasket to allow a press bolt to pass through the hole of the fixing ring, thereby preventing displacement in the operation process. The sealing rubber gasket has the advantages of good sealing effect, simple structure, good location effect and easy operation.

Description

Pipe first-aid joint sealing rubber pad

Technical field:

The utility model relates to the annex that various pipelines are rushed to repair joint fast, belongs to the pipe first-aid technical field, is a kind of pipe first-aid joint caulking gum packing ring that seals skewed slot that has specifically.

Background technique:

Rush to repair fast at pipeline in (can not stop pipeline work) process, line transportation thing (liquids and gases) quality non-leakage, sealing just is the key link; Pipeline is big, pipe internal pressure height causes adverse influence to pipe first-aid especially; In existing technology, adopt the housing of rubber pad usually by a pair of " () " type, link together with bolt, be fixed on that damaged pipeline place rushes to repair.Because the rubber pad unreasonable structure is located not firm (displacement in operating process easily), airtight quality is not high.

Summary of the invention:

The purpose of this utility model provides a kind of good airproof performance, and is simple in structure, and polarization is good, the maneuverable pipe first-aid joint sealing rubber pad that seals skewed slot that has.

The technical solution adopted in the utility model:

Pipe first-aid joint sealing rubber pad, include the rubber washer that coincide with pipe first-aid joint edge, it is characterized in that: there is the edge described rubber washer both sides, on the described edge mounting hole is arranged, the forward and backward side of the semicircular inner walls of described rubber washer has the one or more skewed slots towards the inboard respectively.

Advantage of the present utility model:

Compared with the prior art, the utility model adopts rubber pad two arc ends respectively to adopt the three seals skewed slot, three road protective actions is arranged when holding tube wall tightly, and adopted retaining ring in the rubber both sides, make hold-down bolt pass hole in the retaining ring, in operating process, be not easy to change the position more; Have good airproof performance, simple in structure, polarization is good, maneuverable advantage.

Embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing and example:

Referring to Fig. 1-5;

A kind of pipe first-aid joint sealing rubber pad, include the rubber washer that coincide with pipe first-aid joint edge, there is edge 3 the rubber washer both sides, and mounting hole 1 is arranged on the described edge, and the forward and backward side of the semicircular inner walls 2 of described rubber washer has three skewed slots 4 towards the inboard respectively.

A pair of rubber washer during repairing (two) is placed on respectively in the interior fixed groove of a pair of " () " shell body, there is the housing of rubber pad to be stuck in the pipeline place that to repair with a pair of, bolt is passed the circular hole of housing and rubber washer retaining ring, hold-down bolt, housing is under the effect of rubber pad, tightly hold tube wall tightly, make pipeline non-leakage.

This rubber pad is by the mould compression molding, and its characteristics are that rubber pad two semicircular inner walls respectively adopt three seals skewed slot (seeing accompanying drawing 3), have three road protective actions when holding tube wall tightly, because skewed slot is inwardly tiltedly, outwards expand when in the pipeline pressure being arranged, hold tube wall more tightly, sealing is just better.For better location, unshift in using operation, we have adopted edge 3 in the rubber both sides, make hold-down bolt pass mounting hole 1 in the edge, and rubber pad just has been not easy displacement in operating process like this.

Claims

1. pipe first-aid saves sealing rubber pad, include the rubber washer that coincide with pipe first-aid joint edge, it is characterized in that: there is the edge described rubber washer both sides, on the described edge mounting hole is arranged, the forward and backward side of the semicircular inner walls of described rubber washer has the one or more skewed slots towards the inboard respectively.
