Description

TECHNICAL FIELD

[0002] The pipeline leaks after being used for a period of time due to corrosion and abrasion, and the pipeline wall has leakage points. The leakage points are generally in the form of holes or strips. Polyurethane foam sealant is generally used to plug the leakage points on the pipeline wall. The polyurethane foam sealant is directly injected into the leakage points by a plugging agent injection device for filling and plugging. However, the pressure at the leakage point of the pipeline is high, and the polyurethane foam sealant cannot adhere well to the pipeline wall. The plugging effect of the polyurethane foam sealant on the high-pressure pipeline is not good, and additional reinforcement is needed on the pipeline. In addition, the space around the pipeline is usually small, and the plugging operation of such a pipeline needs to consider the interference with the surrounding pipelines and other situations, which is inconvenient to operate.

The device includes an internal fixed ring body and an external fixed ring body. The external fixed ring body is sleeved outside the internal fixed ring body. A connecting reinforcing member is arranged between the fixed ring body and the external fixed ring body. A glue filling chamber for placing a high molecular material is arranged between the internal fixed ring body and the external fixed ring body. The device has the advantages of providing a preliminary sealing effect for the leakage conduit and resisting high pressure through the internal fixed ring body. The external fixed ring body provides a compression load. The high molecular sealing material seals the leakage liquid, thereby achieving a three-layer sealing and reinforcing effect for the leakage pipeline. The operation process is simple and convenient, and the device is not easily affected by the surrounding pipelines, and has high installation efficiency.

[0004] When the relatively viscous plugging liquid flows into the hydraulic conduit, the flowability is poor due to the small internal space of the hydraulic conduit, which results in poor filling effect of the plugging liquid and poor plugging effect of the hydraulic conduit.
