Pipeline reconstruction sealing protective cover structure

Abstract

The invention relates to a pipeline reconstruction sealing protective cover structure. The pipeline reconstruction sealing protective cover structure is characterized in that the pipeline reconstruction sealing protective cover structure is arranged at the fracture position of a single pipeline or the joint of a plurality of pipelines; and the pipeline reconstruction sealing protective cover structure comprises at least two shell structures, and the two shell structures include the pipeline reconstruction sealing protective cover upper shell and the pipeline reconstruction sealing protective cover lower shell. According to the pipeline reconstruction sealing protective cover structure, the outer sides of the pipelines are wrapped by a pipeline reconstruction sealing protective cover at thejoint of the pipelines; even if the pipelines are in a leaking state, leakage stopping can be completed without power failure and shutdown; pressure relief holes are formed in the shells, the pressure relief holes are opened in the leakage stopping process and blocked after blocking glue is solidified, and leakage stopping under the pressure state can be achieved; and besides, the blocking glue is only arranged at the joint gap of the shells, and bolts are not sealed, so that the blocking glue is convenient to remove in the later period, and the reconstruction sealing protective cover is convenient to reuse.

Description

Technical field[0001]The invention relates to the technical field of pipeline plugging, in particular to a pipeline reconstruction sealing protection cover structure.Background technique[0002]Generally, the medium pipelines for power use are usually used to circulate sulfur hexafluoride or transformer oil; and the plugging joints of the pipeline and the plugging of the end of the pipeline need to be sealed; but after long-term use, The sealing ring is prone to aging, or sometimes the sealing performance of the seal is poor, and it is easy to cause leakage. The common method is to wrap the sealant as a whole at the sealing point. This wrapping and sealing method cannot complete the gel seal when gas leakage occurs, because the leakage When blocking, it will produce air pockets, resulting in unsatisfactory blocking effects; in addition, this sealant is directly wrapped on the plug in a fully sealed manner, or even directly wrapped on the bolts on the plug, resulting in poor subsequent...
