Embodiment Construction
[0037] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0038] see figure 1 , The online pipeline leak plugging device 100 provided by the present invention mainly includes two parts: a sealing part 101 and a pressure relief fastening part 102 .
[0039] The sealing part 101 is glued on the pipeline along the circumferential direction of the pipeline 200 through the sealing glue 101a, and is distributed on both sides of the leakage opening on the pipeline, so as to realize the sealing between the leakage plugging device 100 and the leakage pipeline 200, preventing The medium leaks from the contact portion between the pipeline 200 and the leakage blocking device 100 .
[0040] Such as figure 2 As shown, in the specific setting, the sealing member 101 is an annular sealing member with a certain widt...

The invention discloses a device and method for conducting online pipeline leakage stoppage. The leakage stoppage device is mainly composed of adhesive sealing components and decompression fastening components, wherein the adhesive sealing components are matched with the decompression fastening components. During leakage stoppage, first, adhesive sealing positions of the adhesive sealing components are marked according to the position of a leaking opening on a pipeline; then, a group or a plurality of groups of adhesive sealing components are adhered on the marked adhesive sealing positions on the pipeline through adhesive sealing glue; then, decompression valves on the decompression fastening components are opened, and the decompression fastening components corresponding to the adhesive sealing components are clamped on the pipeline; and finally, the decompression valves on the decompression fastening components are closed, and the leakage stoppage is finished. By means of the scheme, fast online leakage stoppage for a soft pipeline or a hard pipeline can be achieved.
Description
technical field [0001] The invention relates to a pipeline plugging technology, in particular to an online pipeline plugging technology. Background technique [0002] The fire hose is an important equipment for the fire brigade to transport fire extinguishing agents, and plays a vital role in fire fighting and rescue. In fire fighting, fire hoses are often scratched due to aging materials or encountering sharp objects such as hard protrusions, resulting in damage and water leakage. The water leaking out under high pressure not only adversely affects fire fighting and rescue, but may also cause serious consequences. Especially in the fire rescue scene, once the main line hose breaks, it will directly affect the water supply in the front field. To replace the new hose, the water pump needs to be stopped, which wastes a lot of time. This is very undesirable for fire fighting and rescue where every second counts. At this time, there is a need for a method to block the leak of ...
