Elastic plugging valve for pipeline

Abstract

The invention relates to an elastic plugging valve for a pipeline. The elastic plugging valve comprises a plugging valve body, the plugging valve body is of an arc-shaped structure, and the outer diameter of the arc-shaped structure is matched with the inner diameter of a to-be-repaired pipeline. The plugging valve body is provided with an elastic mechanism capable of being contracted or expanded and a retracting and releasing locking mechanism, and the outer surface layer of the plugging valve body is coated with an anti-seepage cushion layer. The outer diameter of the arc-shaped structure is matched with the inner diameter of the to-be-repaired pipeline, in other words, the outer diameter of the plugging valve body is smaller than the inner diameter of the to-be-repaired pipeline after the plugging valve body is contracted, and the inner diameter of the plugging valve body can be enlarged and the plugging valve body can abut against the inner side face of the to-be-repaired pipeline by means of expansion force of an elastic mechanism of the device after the plugging valve body is expanded. When the device is in use, a robot commonly used in the existing market and used in a pipeline is applied, the device is conveyed to the to-be-repaired position of a broken hole of the pipeline, then the locking mechanism is released, the blocking valve body is opened to abut against the wall of the sewage pipe through the elastic mechanism of the device, and the broken hole position is plugged through the anti-seepage cushion layer. The defects of large work amount, long time and high cost caused by digging for old pipe replacement in the prior art can be overcome.

Description

technical field [0001] The invention belongs to the technical field of municipal pipeline engineering, and in particular relates to a device which can effectively and quickly solve the water leakage of the current sewage pipeline through holes. Background technique [0002] With the development of urbanization, the aging of sewage facilities in urban areas, especially sewage pipes, is an unavoidable reality. Coupled with heavy and frequent traffic on the road, the sewage pipes and related facilities built in the early stage often have different degrees of damage, especially It is more common to leak water from pipe holes. However, if these broken pipes are repaired, the conventional method is to excavate the road surface and pull in new pipes for repair. This solution obviously has the defects of large impact, long working hours and high cost. If it cannot be repaired in time, it will be left to exist Sewage seepage will cause serious pollution. Therefore, it is necessary t...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the defects of large amount of work, long time and high cost in the prior art that all damaged pipelines are excavated and replaced, and propose a simple, fast, low-cost, light workload and energy-saving pipeline. A device that reliably and effectively seals the position of the hole in the pipeline point to point, thereby solving the problem of the hole in the sewage pipe and the sewage seepage caused by it
