The pipeline can be plugged after the annular inflatable bag 01 is contacted with the pipeline, so that the pipeline can be effectively plugged, and the phenomenon that residual liquid in the pipeline flows to a leakage point to influence the normal operation of repair welding work is avoided. Because the first baffle 03 and the second baffle 04 are positioned at two sides of the annular inflatable bag 01, and the annular inflatable bag 01 is inflated to contact with the plate surface of the first baffle 03, the plate surface of the second baffle 04, the side wall of the connecting rod 02 and the inner wall of the pipeline, namely, the annular inflatable bag 01 is surrounded by the first baffle 03, the second baffle 04 and the pipeline, sparks or welding slag generated in repair welding leakage points are not easy to contact with the annular inflatable bag 01 to scald the rubber airbag, so that the rubber airbag cannot leak air, and residual liquid can be effectively blocked.
