Magnetic pressure leak blockage device pole shoe capable of automatically adapting to container arc degree

Abstract

The invention relates to a pole shoe used in a magnetic-pressure sealer capable of automatically fitting with the curvature of a vessel. A main body (2) of the pole shoe is symmetrically provided with two pedestals (2-1) with a magnetic-isolation bar (3) sandwiched therebetween, wherein the two pedestals (2-1) are connected with each other by the magnetic-isolation bar (3), forming an entire body. A rotating pole shoe (4) is arranged inside the arc-shaped chamber of each of the two pedestals (2-1) and has a rotating arched magnet (4-1) on the top. The rotating arched magnet (4-1) is shaped to fit with the arc-shaped chamber, is positioned inside the arc-shaped chamber, and can rotate inside the arc-shaped chamber. A flat plate (4-2) is arranged at the bottom of the rotating arched magnet (4-1) and positioned on a glue-coated sheet (1). A magnetic-isolation bar (5) on the glue-coated sheet (1) is positioned opposite to leak holes (9) on the magnetic-isolation bar (3) and a larger pipeline (8).

Description

technical field [0001] The invention relates to a pole piece of a magnetic pressure leak plugging device which can automatically adapt to the radian of a container, in particular to a pole shoe of a magnetic pressure leak plugging device which is installed at the bottom of the magnetic pressure leak plugging device to block the leakage of gaseous and liquid dangerous chemicals. Background technique [0002] When leaks occur in large pipelines, tanks and other containers that store and transport hazardous chemicals, magnetic leak plugging devices are often used to press the plugging glue onto the leak port to seal the leak. Because the radians of the surface of the leakage container and the bottom surface of the magnetic pressure leak plugging device are generally not exactly equal, there will always be a large air gap between the two. The magnetic pressure drop generated by this air gap is very large, which greatly reduces the magnetic pressure. The magnetic pressure of the ...

Problems solved by technology

At present, there are two ways to solve this problem: one is to make the bottom surface of the magnetic pressure leak stopper into a V-shaped groove. If the surface of the container is tangent to both sides of the V-shaped groove at the same time, the average air gap can be appropriately reduced. But in fact, this method is not feasible, because the diameter of the container is large, and the size of the magnetic leak plugging device is small, the contact between the two can only be limited to the opening of the V-shaped groove, and it is impossible to be tangent to the planes on both sides. , and it is impossible to reduce the average air gap; Second, some manufacturers specially equip the magnetic pressure leak plugging device with multiple pole pieces, and their working surface radians are different. However, due to the different diameters of various leakage containers, no matter how many pole pieces are matched, there will still be a large air gap between the two, and too many pole pieces are inconvenient to carry, which directly affects the emergency plugging of dangerous chemicals Effect
