Abstract

The utility model relates to a pipeline joint for maintenance. The pipeline joint for maintenance comprises an upper joint, a lower joint and sealing parts. The upper joint and the lower joint are respectively composed of two semi-circular structures which are fixedly connected through first fasteners, sealing grooves are formed in connections between the semi-circular structures of the upper joint, and sealing grooves are formed in connections between the semi-circular structures of the lower joint. The upper joint and the lower joint are fixedly connected through ring-shaped second fasteners which are evenly distributed, and a ring-shaped sealing groove is formed in the connection between the upper joint and the lower joint. Ring-shaped grooves are formed in the inner surface of the upper joint and the inner surface of the lower joint. The inner diameter of the upper joint and the inner diameter of the lower joint are matched with the outer diameter of a damaged pipeline. The sealing parts are arranged in the sealing grooves, the ring-shaped sealing groove and the ring-shaped grooves. Hoisting rings are arranged on the outer surface of the upper joint and the outer surface of the lower joint. The pipeline joint for maintenance has the advantages that on-line maintenance is achieved, pipeline maintenance is convenient and rapid, cost is reduced, valves at the upstream position of the damaged position of the pipeline do not need to be closed, users at the downstream position of the pipeline cannot be influenced, and the service life of the pipeline is prolonged.

Description

A kind of maintenance pipe coupling
Technical field
The utility model relates to a kind of maintenance pipe coupling.
Background technique
The fluid Main Ingredients and Appearance that general hot duct is carried is water, even water also has corrosive action to pipeline, because the pipeline of corrosion and damage is generally local damage, rather than the integral body of pipeline is damaged.When situation appears leaking in pipeline, usually adopt and close the place's upper reaches valve that leaks, after waiting for the fluid discharge pipe road in the pipeline, the method that the pipeline of local damage repairs or replaces is keeped in repair, the general means that adopt welding of maintenance, be about to the damaged position of pipe fitting and seal with the method for welding, and welding needs specialized apparatus, cost is higher relatively.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model provides a kind of maintenance pipe coupling, and is easy for installation, can carry out on-line maintenance, reduces the wasting of resources, reduces maintenance cost.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of maintenance pipe coupling comprises upper connection, lower contact, Sealing, and described upper and lower joint is made up of two semi-circular structure, and fixedly connected by fastening piece one, and the joint is provided with seal groove; Upper and lower joint is fixedly connected by the uniform fastening piece two of annular, and the joint is provided with annular seal groove; Described upper and lower joint internal surface is equipped with circular groove; Described upper and lower joint internal diameter and damaged pipe external diameter are complementary; Be equipped with Sealing in described seal groove, annular seal groove, the circular groove.
Described lower contact internal surface is provided with positive stop lug boss.
Described upper and lower joint outer surface is provided with hoisting ring.
Compared with prior art, the beneficial effects of the utility model are:
Realized on-line maintenance, pipeline maintenance is convenient and swift, saves cost, and the valve that does not need to close pipeline breakage upstream can not make the pipe downstream user be affected, and prolongs pipeline working life.
Description of drawings
