Self-pressure-relief pipeline leakage repairing device

Abstract

The invention provides a self-pressure-relief pipeline leakage repairing device, and relates to a pipeline leakage repairing sleeve. A protruding pipe (15) is arranged in the middle of the outer face of a semicircular plate (13), an opening (8) corresponding to a pressure relief opening (14) is formed in the middle of a rubber plate (7) arranged on the inner face of the semicircular plate, and vertical plates (12) are arranged at the two ends of the semicircular plate respectively; a notch (17) is formed in the pipe wall of the protruding pipe, and an internal thread (20) of a blocking cap (22) is partially connected with an external thread (16) of the protruding pipe; and a leakage point (25) on one side of a pipeline (24) corresponds to the pressure relief opening of the semicircular plate, the two sides of a locking plate (3) are movably clamped to the inner faces, close to the outer ends, of the two vertical plates (12), a top plate (6) abuts against the other side face of the pipeline, a screw (5) on the outer side face of the top plate is adjusted through a screw hole (2) in the middle of the locking plate to abut against the pipeline, and the blocking cap completely covers the external thread of the protruding pipe. The notch formed in the protruding pipe is used for relieving the pressure of leaked liquid, and rapid repairing of the pipeline is facilitated.

Description

【Technical field】 [0001] The invention relates to the technical field of a leak-trapping sleeve for a pipeline, in particular the invention is a leak-trapping device for a self-relieving pipeline. 【Background technique】 [0002] It is known that liquid water, liquid raw materials, etc. are transported through pipelines. In long-term use, leaks are prone to occur due to corrosion, fluid friction, hot and cold weather, collisions or quality problems. The pressure in pipeline leakage repair operations is low or The valve that can enter the direction of the pipe wall can be repaired by conventional methods; if the inlet valve cannot be closed during pipeline maintenance, and the pipeline with high pressure cannot be relieved, the existing double semicircular pipeline leak-trap tooling cannot be buckled under the influence of the pressure. On the pipeline, even after it is buckled on the pipeline, the splashed liquid will damage the sealing rubber strip, making it extremely diffi...

[0002] It is known that liquid water, liquid raw materials, etc. are transported through pipelines. In long-term use, leaks are prone to occur due to corrosion, fluid friction, hot and cold weather, collisions or quality problems. The pressure in pipeline leakage repair operations is low or The valve that can enter the direction of the pipe wall can be repaired by conventional methods; if the inlet valve cannot be closed during pipeline maintenance, and the pipeline with high pressure cannot be relieved, the existing double semicircular pipeline leak-trap tooling cannot be buckled under the influence of the pressure. On the pipe, even after it is buckled on the pipe, the splashed liquid will damage the sealing rubber strip, making it extremely difficult to repair the pipe
