Description

Technical Field

[0001] The utility model relates to the technical field of pipeline plugging covers, in particular to a plugging cover for quick pipeline plugging. Background Art

[0002] Pipelines have become an important part of urban infrastructure construction, especially large pipelines. In order to ensure that the pipelines do not break during daily use and cause liquid or gas leakage, old pipelines are usually repaired or replaced in pipeline renovation projects. Therefore, when replacing them, they need to be sealed with a plugging cover.

[0003] In the prior art, a patent document with the announcement number CN217422616U proposes a wrapped pipeline leakage plugging device, including a plugging slip, a butt rod, a gland plate, and a sealing gasket. The butt rod connecting plates on both sides of the plugging slip are connected with two butt rods. A circular through hole is opened on the top boss structure of the plugging slip, and the gland plate with a sealing gasket at the bottom is inserted into the circular through hole. The gland plate is continuously pressed down by continuously tightening the locking and anti-loosening nuts to further improve the sealing effect. This patent uses a clamp-type plugging device to hold the outer wall of the pipeline, uses a radial sealing device to achieve sealing of the leakage position, and uses double nuts to lock the vertical screw and the butt rod to reduce the risk of sealing failure; the plugging slip with a single-slip structure enables the plugging device to have good pipeline deformation control capabilities; this patent has a simple structure, low manufacturing cost, and convenient installation and operation, which can effectively shorten the maintenance period of leaking pipelines.

[0004] In order to solve the problem that the traditional mechanical sealing pipe clamp cannot be used when the pipeline has certain irregular deformations and abnormal protrusions that cannot be polished, the existing technology adopts a clamp-type sealing device to hold the outer wall of the pipeline and use a radial sealing device to achieve the sealing of the leakage position. However, the sealing device still needs to be installed with the help of tools during use, which reduces the practicability of the sealing device. Utility Model Content
