Problems solved by technology

[0002] Pipeline leakage often occurs. On July 7, 2000, a major poisonous gas leakage accident occurred in Chengdu-Chongqing Expressway. Due to the lack of corresponding sealing equipment and corresponding sealing methods, a large amount of poisonous gas leaked and many firefighters were poisoned.
On March 29, 2005, liquid chlorine leaked from the Huaian section of the Beijing-Shanghai Expressway; on August 18, 2009, Chongqing styrene poisonous gas leaked; on August 5, 2009, ammonia gas leaked in Chifeng, Inner Mongolia, also because there was no corresponding sealing device And its corresponding plugging method, causing significant economic losses
[0005] The above-mentioned different plugging devices and plugging methods for different existing pipeline leakage are inconvenient in actual use, the scope of application is relatively limited, and the operation is relatively complicated. There are high professional requirements for operators

Embodiment approach 1

[0039] Such as Figure 1-Figure 16 , implement a kind of risk source pipeline leakage external plugging air bag and its fast plugging method of the present invention, its mechanical structure mainly includes the position adjustment clamping mechanism on the left side, the position adjustment clamping mechanism and the plugging mechanism on the right side; The clamping mechanism is used to clamp the outer surface of the pipeline to fix the relative movement of the left and right ends of the sealing mechanism; the sealing mechanism uses the ductility and sealing of the rubber to obliquely superimpose and wrap the rubber air cushion on the leaking part of the pipeline, and uses the inflation valve to give The rubber air cushion is inflated, and the gas continuously enters the belt-type rubber air cushion to make each layer of air cushion tighten and squeeze each other to quickly seal the leaking part of the pipeline.

Embodiment approach 2

[0043] Such as Figure 1-Figure 16, implement the present invention a kind of risk source pipeline leakage outer sealing air bag and its fast sealing method, its pipeline leakage outer sealing air bag is assembled as follows:

[0044] First assemble the left and right position adjustment clamping mechanism, first connect the inner collar 1 and the deck 10 through the four screw holes of the deck screw 15 at 11-1, and the outer collar 9 is connected through the 10 of the deck 10. Insert at -1, then inlay the rubber gasket 3 in the ring formed by the inner collar 1 and the outer collar 9, the hook seat 2 is connected with the inner collar 1 at 2-1 by four hook seat screws 14 Together, the outer collar 9 is connected with the support 7 at 4-1 through 4 support screws 13, and then the tension handle 5 is connected to the support hole at 4-2 of the support 7 with the connecting bolt 12 On the 8-1 place in the middle of the tensioning handle 5, the movable draw hook 4 is connected ...

Embodiment approach 3

[0047] Such as Figure 1-Figure 16 According to the present invention, a kind of risk source pipeline leakage external sealing airbag and its fast sealing method are implemented. The operation process of sealing the leakage opening on the outer surface of the pipeline is to firstly clamp the position adjustment and clamping mechanism on the left side to the leakage opening of the pipeline. On the side, put the movable pull hook 4 on the hook seat 2, buckle and pull the handle 5, so that the clamping mechanism can be clamped on the pipeline, without considering the sealing, unfold the belt-type rubber inflatable cushion 11, wrap it obliquely layer by layer and pass through At the leakage port, wrap and superimpose multiple layers at the leakage port. If the leakage port is long, it can be wound densely and obliquely. Finally, clamp the clamping mechanism on the right side to the pipe; then inflate the inflation valve 8, Until the belt-type rubber inflatable cushion 11 expands a...

Abstract

The invention relates to a gasbag for the outer blockage of the leakage of a pipeline with a risk source and a quick blockage method thereof. The blockage gasbag disclosed by the invention is formed by hinging the left ends and the right ends of belt type rubber inflation cushions through the connecting bolts of the supporting seats of position regulating and clamping mechanisms at the left side and the right side; and in the method disclosed by the invention, the position regulating and clamping mechanism at the left side is clamped at one side of a leakage port of a pipeline at the positionof the leakage port of the pipeline, a movable drag hook is hooked on a hook seat, a tightening handle falls off and is clamped, the belt type rubber inflation cushions are unfolded, layers are inclined, superposed and wound, then the position regulating and clamping mechanism at the right side is clamped on the pipeline for clamping, afterwards inflation is carried out, each layer of inflation cushion is tightly expanded, the inflation cushions also are mutually pressed, and quick blockage is executed to the leakage of the pipeline. In the invention, the structure is simple, the use is convenient, the blockage of the leakage can be effectively and quickly realized, and the gasbag for the outer blockage of the leakage of the pipeline with the risk source is suitable for the blockage of the leakage of harmful gas-liquid pipelines in coal chemical industry, petrochemical engineering and the like.

Description

technical field [0001] The invention relates to a pipeline leakage sealing device and a sealing method thereof, in particular to a risk source pipeline leakage external sealing air bag and a rapid sealing method thereof. It is used for sealing pipeline leakage in the process of petrochemical, coal chemical production, toxic gas and liquid production and storage and transportation, and can also be used for pipeline sealing in gas, heat and water supply emergency. Background technique [0002] Pipeline leakage often occurs. On July 7, 2000, a major poisonous gas leakage accident occurred in Chengdu-Chongqing Expressway. Due to the lack of corresponding sealing equipment and corresponding sealing methods, a large amount of poisonous gas leaked and poisoned many firefighters. On March 29, 2005, liquid chlorine leaked from the Huaian section of the Beijing-Shanghai Expressway; on August 18, 2009, Chongqing styrene poisonous gas leaked; on August 5, 2009, ammonia gas leaked in Chi...
