[0013] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0014] like Figures 1 to 3 As shown, a pipeline flammable and explosive gas leakage plugging tool includes an annular support frame 1, the annular support frame 1 is used to be sleeved on the pipeline 2, a sealing rod 3 is installed on the upper part of the annular support frame 1, a screw hole 4 is provided at the lower part of the annular support frame 1, a fastening screw 5 is installed in the screw hole 4, a support guard plate 6 is rotatably installed on the top of the fastening screw 5, the fastening screw 5 and the sealing rod 3 are arranged in a straight line, a sliding sleeve 7 is sleeved on the sealing rod 3, and a flexible sealing material 8 is provided at the bottom of the sealing rod 3.
[0015] In the utility model, the annular support frame 1 is a rectangular frame, and the top plate of the rectangular frame is fixed on the rectangular frame by bolts, and the sealing rod is fixed on the top plate of the rectangular frame. The top plate can be freely disassembled for easy installation. When the sealing rod 3 squeezes the flexible sealing material at the leakage point of the pipeline, the sliding sleeve 7 is welded on the pipeline 2. The sliding sleeve 7 is fully welded to the pipeline 2.
[0016] The specific implementation method of the utility model is as follows: a matching sealing rod 3 is processed according to the shape of the leakage part, and the soft sealing material 8 is bonded to the vertebral part of the sealing rod.
