Description

Natural gas pipeline leakage repairing device Technical Field The utility model relates to the technical field of pipeline repair, in particular to a natural gas pipeline leakage repair device. Background The gas pipeline is used as an important facility for energy transportation, and the safe operation of the gas pipeline is important. However, due to factors such as aging, corrosion or external damage of the pipeline, natural gas leakage accidents occur sometimes, so that the gas pipeline needs to be inspected periodically. In the inspection process, once a leakage point is found, emergency measures are needed to be immediately taken to prevent a great deal of natural gas from leaking out and avoid secondary disasters such as fire, explosion and the like. In emergency treatment, a winding belt (such as a sealing adhesive tape or a fiber reinforced composite material) is manually wound on the outer side of a pipeline leakage point, and temporary sealing is realized by applying a tensioning force. The method is simple and convenient to operate, and can quickly slow down leakage. The operation steps are as follows: Firstly, the winding belt is in a roll shape, the free end of the winding belt is lifted by one hand and pressed near the leakage point of the gas pipeline, the winding belt is held by the other hand, the winding belt revolves around the gas pipeline under the condition of tensioning the winding belt, spiral winding is carried out, and the winding belt of the next circle presses out the winding belt of the previous circle; After the expansion part of the winding belt is wound on the gas pipeline, the winding pipeline is stopped, the winding belt is controlled to rotate to expand, after a certain length of the winding belt is expanded, the winding belt is tensioned again to revolve and wind the pipeline, the second expansion and the third expansion are carried out in the same way, until the winding belt covers the leakage point of the gas pipeline and winds for a section along the axial direction of the pipeline, and finally, the reinforcement is carried out by brushing a coagulating agent and the like. However, the winding process needs to maintain a relatively uniform and moderate tension, and too much tension can cause deformation of the winding belt or compressive damage to the pipeline, so that the winding belt cannot be effectively sealed when the tension is too small.
