A soft sealing device for the end of a pipeline

Abstract

The invention provides a soft sealing and blocking device for a pipeline end part, and relates to a pipeline end part sealing device. The large end of a conical extrusion surface A (10) is connected onto one side surface of an extrusion pull block (1), the small end of the conical extrusion surface A is connected with one end of an unthreaded rod (8), a rubber expansion and contraction ring (13) and an extrusion jacking block (3) sequentially sleeve the unthreaded rod, two connecting rods (9) of an F-shaped handle (11) are respectively connected onto the two side surfaces of an unthreaded hole (14) formed in the outer side of the extrusion top block, one end of an external threaded pull rod (7) is fixedly connected with the other end of the unthreaded rod, the middle part of the external threaded pull rod is connected with a screw hole formed between two connecting rods of the F-shaped handle through screw threads, and the other end of the external threaded pull rod is provided with a square handle (6). The soft sealing and blocking device for the pipeline end part has the advantages that the extrusion pull block and the extrusion jacking block are used, so that the rubber expansion and contraction ring expands for forming the fast soft sealing and blocking on the pipeline, and the time is won for urgent repair.

Description

【Technical field】 [0001] The invention relates to a sealing device for a pipe end, in particular to a soft sealing device for a pipe end. 【Background technique】 [0002] It is known that outdoor water supply pipes in winter usually break due to the influence of climate. Once the pipe breaks, the pipe needs to be replaced. When there is a suitable pipe, the economic loss caused by water leakage can be avoided by replacing the pipe. If there is no pipeline of suitable length, the economic loss caused by water leakage can only be avoided by closing the main valve, which will prevent other customers from taking water, especially when there is no slipknot at the broken part of the pipeline on the ground, this problem can hardly be solved quickly Solve; the same technical problem also exists in other fluid pipelines of the enterprise, and there is no better way to overcome this technical bias at present. 【Content of invention】 [0003] In order to overcome the deficiencies in t...

Problems solved by technology

[0002] It is known that outdoor water supply pipes in winter are usually broken due to the influence of climate. Once the pipe breaks, the pipe needs to be replaced. When there is a suitable pipe , the economic loss caused by water leakage can be avoided by replacing the pipeline. If there is no suitable length of pipeline, the economic loss caused by water leakage can only be avoided by closing the main valve, which will prevent other customers from taking water, especially in When there is no slipknot in the broken part of the above-ground pipe, this problem is almost impossible to solve quickly; the same technical problem exists in other fluid pipes of the enterprise, and there is currently no good way to overcome this technical bias
