Problems solved by technology

[0004] The above-mentioned plugging method is mainly to rotate and adjust the fine-tuning anti-loosening screw to press the soft sealing block on the leakage point. However, since the gas pipeline is often buried underground, the fine-tuning anti-loosening screw is easily corroded by corrosive fluid. loosening, resulting in the weakening of the compression effect of the sealing briquetting block on the leakage point, and secondary leakage is prone to occur after a period of plugging

Embodiment 1

[0038] Embodiment 1: a kind of plugging method of gas pipeline, refer to figure 1 with figure 2 As shown, the method includes the following steps in turn:

[0039] a. The emergency repair personnel of the gas company arrive at the scene as soon as possible, prepare fire extinguishers, explosion-proof fans, etc., use experience or equipment to find out the specific leak point of the gas pipeline 1 according to the site situation, and clean up the anti-corrosion substances, rust and impurities on the pipeline around the leak point Clean, so that the surface of the gas pipeline 1 around the leakage point is smooth;

[0040]b. According to the diameter of the gas pipeline 1, select a leak-stopping device that matches the diameter of the gas pipeline 1, wrap the soft body 2 on the leak-stopping device on the gas pipeline 1 in a ring shape, and The first end portion 201 and the second end portion 202 are fixed together, the soft body 2 and the gas pipeline 1 are sleeved relativel...

Embodiment 2

[0043] Embodiment 2: a leak plugging device, used to realize the above embodiment 1, such as figure 1 As shown, it includes a soft body 2 wrapped around the gas pipeline 1. The soft body 2 is made of soft material and can be curled and bent to form a ring. The two ends of the soft body 2 are the first ends respectively. part 201 and second end part 202, after the soft body 2 is fastened and wound on the gas pipeline 1, the first end part 201 and the second end part 202 are bonded and fixed by glue 3, and the glue 3 adopts anti-corrosion Sexual glue 3, preferably acrylic type adhesive, acrylic type adhesive has adhesiveness and anti-corrosion, adopts the mode of coating to fix and bond the first end 201 and the second end 202, can avoid the second The connection between the first end 201 and the second end 202 is affected by the corrosion of corrosive substances, and the bonded soft body 2 is firmly attached to the outer circumferential surface of the gas pipeline 1 .

Abstract

The invention discloses a leaking stoppage method and a leaking stoppage device for a gas pipeline, wherein the leaking stoppage method comprises the following steps that b, a soft body of the leaking stoppage device is wound and arranged on the gas pipeline in a sleeving manner, the soft body and the gas pipeline are fastened in a sleeving mode, a sealing body on the soft body is tightly attached to the outer circumferential surface of the gas pipeline, a gap between the soft body and the gas pipeline is sealed in the width direction of the soft body, an airtight cavity is formed between the soft body and the gas pipeline, leaking points are correspondingly covered with compaction blocks on the leaking stoppage device, and the amount of gas leaked from the leaking points is reduced; c, an air valve on an air nozzle is opened, an air bag is inflated in a manner of extruding a rubber ball, compaction blocks on the air bag tightly press the leaking points, the leaking points are sealed, the air bag is continuously inflated until the leaking points are completely sealed by the compaction blocks, the air valve is closed to keep the leaking points always tightly pressed by the compaction blocks, leaking stoppage work is more convenient and labor-saving, the air compaction effect is remarkable, and secondary leakage is not prone to generating.

Description

technical field [0001] The invention relates to a gas pipeline plugging technology, in particular to a gas pipeline plugging method and a device for realizing the method. Background technique [0002] With the continuous improvement of living standards, people have higher and higher requirements for residential interior decoration, and the way of laying indoor gas pipelines directly affects the decorative effect of residential interiors. Because the gas pipeline is buried in the dark, it is not easy to be found after the pipeline leaks, and it is difficult to deal with the leakage fault, which has buried hidden dangers for the safety of the gas pipeline. [0003] At present, in the prior art, in a Chinese patent document with the authorized announcement number CN101900238B, a method for plugging gas pipelines without stopping gas and welding is recorded, and a soft sealing briquette that matches the size of the leakage point is selected. , placed between the arc-shaped comp...
