Embodiment 1

[0030] Embodiment 1: as figure 1 As shown, a pipe elastic plugging valve includes a plugging valve body 1, the plugging valve body 1 is an arc-shaped structure, its outer diameter is compatible with the inner diameter of the pipeline to be repaired, and its radial dimension can be contracted or Zoom in, the plugging valve body 1 is provided with a retractable or expandable elastic mechanism and a retractable locking mechanism, and the outer layer of the plugging valve body 1 is coated with an anti-seepage cushion layer 2; Compatibility means that the outer diameter of the arc-shaped structure of the plugging valve body 1 is smaller than the inner diameter of the pipeline to be repaired after contraction, and can rely on the expansion force of the elastic mechanism of the device to expand the inner diameter and press tightly against the pipe to be repaired after being opened. Repair the inner surface of the pipeline, and use the anti-seepage pad 2 of the outer layer to block th...

Embodiment 2

[0034] Embodiment 2: The plugging valve body 1 is made of a non-closed quasi-spiral high-elasticity steel plate 11, the quasi-spiral-shape high-elasticity steel plate 11 is rolled into shape and heat-treated to make its outer diameter larger than that in the free state. The inner diameter of the pipeline to be repaired, the quasi-spiral-shaped high-elasticity steel plate 11 elastically deforms and shrinks under the action of external pressure and closes, and the outer diameter is smaller than the inner diameter of the pipeline to be repaired, and the openings are staggered and superimposed; the two edges of the opening are provided with a retractable locking mechanism The retractable locking mechanism includes at least two superimposed coaxial lugs 10 fixedly connected to the two edges of the opening of the quasi-spiral high-elasticity steel plate 11, and two lugs 10 corresponding to the upper and lower edges. A pair of locks, all the through holes of each pair of locks are ins...

Embodiment 3

[0038] Embodiment 3: The plugging valve body is made of a non-closed quasi-cylindrical high-elastic steel plate 12 that is rolled up similar to Embodiment 2, but one side of the opening is provided with a step 13 using an inwardly turning structure. All the other structures, materials and techniques are the same as in Example 2. The quasi-cylindrical high-elastic steel plate can make the roundness better after the locking mechanism is released, and its elastic force is much greater than that of the coil spring, which is more conducive to fitting and adapting to the shape of the pipeline to be repaired. see Figure 6 , Figure 7 .

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...
