PE pipeline under-pressure plugging and repairing device

Abstract

The invention provides a PE pipeline under-pressure plugging and repairing device, and relates to the field of PE pipelines. The PE pipeline under-pressure plugging repairing device comprises a limiting sleeve, the inner side of the limiting sleeve is fixedly connected with a clamping hook, the side face of the limiting sleeve is fixedly connected with a clamping motor, the output end of the clamping motor is fixedly connected with a pushing gear, the pushing gear is meshed with the clamping hook, the lower end of the pushing gear is meshed with a plugging rod, and the plugging rod is slidably connected with the limiting sleeve. The surface of the plugging rod is slidably connected with a connecting plate, the connecting plate is connected with a hot melting ring through screws, and the outer surface of the clamping hook is fixedly connected with a connecting frame. According to the PE pipeline under-pressure plugging and repairing device, a sewing and repairing device for a plugging notch is placed on the inner side of a plugging rod, so that the plugging rod directly presses the leakage of the plugging notch when being pushed, a fixing device is clamped through a clamping hook, a leaked pipeline can be rapidly plugged, and the rapid plugging effect is achieved; the problem that hot melting cannot be carried out on water drops existing at the pipeline repairing position is solved.

Description

technical field [0001] The invention relates to the field of PE pipelines, in particular to a pressure blocking and repairing device for PE pipelines. Background technique [0002] PE material pipes, especially large-diameter pipes, are being widely used in recent years because of their excellent corrosion resistance, high elasticity and plasticity, easy long-distance laying and long service life. Due to reasons such as manufacturing, installation and force majeure, the pipeline will be damaged or even broken, resulting in waste of materials, production stoppage, environmental pollution and even major accidents. [0003] PE material pipes are usually repaired by hot-melt welding, but hot-melt welding needs to empty the pipes, and it is almost impossible to empty the pipelines laid underground. Devices that are repaired in the state. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention provides a PE pipeline pressure pluggi...
