Abstract

A quick repair joint belongs to the pipeline connecting component. The device mainly solves the shortcomings of the existing pipe joint used in the pipeline connection of the emergent repair and construction, that is, the weak shell strength, vulnerable breaking, inconvenience in the construction and operation; the shortcomings influence the repair rate and the sealing rubber ring may fall off. The utility model is composed of an upper shell and a lower shell with a fixing hole and a flute at the end, an upper sealing gasket and a lower sealing gasket and a bolt; the utility model is characterized in that the upper sealing gasket and the lower sealing gasket are provided with the connecting holes matching the fixing holes on the upper shell and the lower shell. The utility model has the advantages of simple structure, high shell strength, easy and convenient construction and operation and firm fixation of the sealing rubber gasket.

Description

Rush to repair pipe joint fast

Technical field

The utility model belongs to pipe connecting part, specifically a kind of pipe joint that is used for connecting tube in the pipeline breaking first-aid repair construction.

Background technique

At present, there is following defective in the pipe joint that is used to connect various pipelines in pipeline breaking first-aid repair construction such as running water pipe, gas-tank, oil feed pipe: 1, since the groove of inboard, housing two end part be interconnected with the groove that two planes vertically are provided with, therefore, casing rigidity is poor, in pipe first-aid, often take place the bolt connection part because of the former of groove so fracture; 2, O-ring seal is to position by gluing being embedded in the groove of brute force, not only can pollute water quality in the pipe because of the toxicity of mighty bond, and O-ring seal can come off under the washing away for a long time of medium in pipe, influences sealing effect; 3, the maintenance man must tight a bolt simultaneously and can fix going up lower shell body with two spanners from start to finish, and operation is inconvenience very, is difficult for the location, and construction speed is slow, influences repairing speed; 4, draining (gas) hole is not set on the housing, the on-the-spot fitting operation of influence repairing.

Summary of the invention

The purpose of this utility model be at above-mentioned deficiency provide a kind of simple in structure, casing rigidity is high, constructing operation is convenient and swift, the quick repairing pipe joint of seal rubber pad fixation.

The utility model is achieved in that by pad in the upper shell that has fixed hole and end recesses and lower shell body, the sealing and sealing underlay and bolt to be formed, it is characterized in that pad in the said sealing and seal underlay being provided with the attachment hole that matches with fixed hole on upper shell and the lower shell body.

The counterbore of the aperture of the fixed hole on above-mentioned lower shell body or the upper shell for matching with bolt head.

Said upper shell or lower shell body also have the weep hole by the plug shutoff.

The inboard, end of pad and sealing underlay is an odontoid in the said sealing.

The utility model will seal pad and sealing underlay and housing by attachment hole and fix, rather than be embedded in the groove by brute force is gluing, medium in the pipe is not polluted in not only fixation, and since not on housing vertically two planes groove is set, thereby can improve the intensity of housing; The aperture of the fixed hole on lower shell body or the upper shell is set to counterbore, in the mistake that tights a bolt becomes, bolt head is subjected to the restriction of counterbore, can not rotate with the rotation of spanner, be that the maintenance man need only just can fix upper shell and lower shell body quickly and easily with a wrench operated from start to finish, thereby realize the purpose of repairing fast; The inboard, end that pad and sealing underlay are gone up in sealing is set to odontoid, be not round at the pipeline of being rushed to repair, or when having surface corrosion, defective such as rough and uneven in surface, realize tight sealing to pipeline by the resiliently deformable that is produced because of extruding between profile of tooth and the pipeline; The weep hole of upper shell or lower shell body setting can be drained the water in upper shell and the lower shell body at any time, thus the on-the-spot fitting operation of convenient repairing.The utlity model has simple in structure, casing rigidity is high, constructing operation is convenient and swift, the advantage of O-ring seal fixation.
