Strong magnetic blocking device and its blocking method

Abstract

One of the strong magnetic blocking device is one leakage-blocking block with notch for strong magnet to be embedded in the outer surface and blocking sealing layer in the inner surface, with the blocking surface having minimum curvature radius of 10 mm and angle of 1-180 deg.c. The other strong magnetic blocking device in one cylindrical holder with strong magnet inside the notch in the bottom and sealing surface of minimum radius 100 mm in the bottom. during blocking leakage, strong magnetic blocking device in proper shape is first selected and then made to be attracted to the surface to be blocked. The present invention has the advantages of simple operation and fast installation and may be used in in-situ emergency repair without stopping production.

Description

technical field [0001] The invention relates to a plugging device and its application, in particular to a strong magnetic plugging device and a plugging method which can be used to plug leakage of various pipelines, storage tanks, underwater hulls, etc. with different curvature radii. Background technique [0002] As we all know, in the petroleum, chemical, marine and other industries, accidents such as leakage of pipeline networks, storage tanks, and underwater hulls often occur. In particular, when petrochemical facilities leak, there are major safety hazards such as fires, explosions, or the spread of poisonous gas. Therefore, fast and effective plugging of leakage points in emergency situations is the key to eliminating major safety hazards. [0003] At present, the general plugging method is: for the leaks and cracks on the plane or curved surface, use an external force to smash a wooden wedge into the leak, or fix the clamp at the crack by...

AI Technical Summary

Problems solved by technology

The above-mentioned existing plugging methods are primitive and backward, and the operation is cumbersome and the speed is very slow. When leakage occurs in the pressure vessel accessories and welds, it is even more difficult to control and deal with it.

Therefore, these plugging methods are not suitable for rescue work under flammable, explosive, critical and dangerous situations when natural gas or highly toxic substances leak such as underwater hulls, petrochemical pipe networks, pipelines and large containers.
