Problems solved by technology
[0002] In the gas storage equipment used in the electric power, petroleum, chemical, and coal industries, the internal gas pressure is often several times or even ten times the atmospheric pressure. If there is a gas leak, it needs to be blocked in time, otherwise the internal gas pressure will drop, or Toxic gas leaks, causing serious hazards
[0003] For high-pressure gas plugging, it is necessary to use extremely high-strength plugging glue. The plugging glue used on site requires a certain setting time, and because the gas flowing out of the leak point is often under high pressure, it is necessary to use a plugging sealant. When leaking, the plugging gel is often "blown out" before it solidifies, which makes it difficult to successfully seal the leak point. Therefore, how to provide a method for plugging the gas storage equipment under pressure to effectively Sealing the air leakage point has become a technical problem to be solved urgently by those skilled in the art

Embodiment Construction
[0026] For ease of understanding, the present invention will be further described below in conjunction with the accompanying drawings.
[0027] see figure 1 , is a flow chart of a method for plugging a gas storage device under pressure according to an embodiment of the present invention, including the following steps:
[0028] S11, close the air inlet of the air guide tube to the gas leakage point of the gas storage device, so that the gas flows out from the air outlet of the end of the air guide tube away from the air inlet.
[0029] In specific practical applications, in order to make the adhesive more firmly bonded to the gas storage device, the surface near the gas storage device's air leakage point can be cleaned and roughened before step S11, for example, with sandpaper, rag, Clean the surface with alcohol, and process the surface with an electric grinding head and a file to make the surface have a certain roughness and improve the bonding and sealing strength of the ad...

The present invention provides a method for plugging leaks under pressure on a gas storage device, comprising: step A: abutting an air inlet of an air conduit against a leak point of the gas storage device to keep gas away from the gas conduit The air outlet at one end of the air inlet flows out; in step B, the end of the air duct close to the air inlet is sealed with the air storage device using an adhesive; step C, the sealing A blocking member is fixedly mounted on one end of the air duct close to the gas outlet, and the blocking member is used for sealing the gas outlet. Using the method provided by the present invention can effectively seal the leak point under pressure.
