Novel electromagnetic pipeline leaking stoppage tool and using method thereof

Abstract

The invention discloses a novel electromagnetic pipeline leaking stoppage tool and a using method thereof. The tool comprises an electromagnet assembly, a connecting bolt, an arc-shaped plate, an asbestos pad, a pressure relief groove, an isolation valve and a pressure relief pipe; the electromagnet assembly controls on-off of an access circuit through the control switch, provides magnetic force when powered on and closes the magnetic force when powered off; the electromagnet assembly is fixedly connected with the convex surface of the arc-shaped plate through the connecting bolt; and the asbestos pad is adsorbed on the concave surface of the arc-shaped plate and combined with the asbestos pad to realize a sealing effect. The using method comprises the five steps of grinding leakage pointsand the periphery, selecting, cutting and repairing vulnerability materials, installing and starting the electromagnet assembly, welding and disassembling the tool. The novel electromagnetic pipelineleaking stoppage tool has the beneficial effects of being simple in structure, convenient and firm to install, convenient to detach, capable of flexibly adapting to pipes of different specificationsand sizes, large in adsorption force and suitable for a low-pressure metal pipeline with the working pressure below 1 Mpa; The tool can be recycled; the cost can be reduced; the working yield can be improved; and the tool can be widely popularized and used.

Description

technical field [0001] The invention relates to a metal pipeline plugging tool with magnetic adsorption, in particular to a novel electromagnetic pipeline plugging tool. Background technique [0002] In industrial production and daily life, various types of pipeline leakage defects often occur. For example, magnetically adsorbed metal pipes such as desulfurization systems, pulverizing systems, and indoor fire protection systems in power plants often leak. To deal with such defects, it is often necessary to stop part of the system and equipment, affecting production efficiency and causing safety hazards. The electromagnetic pipeline plugging tool can quickly deal with such defects and restore the system to normal in time. Contents of the invention [0003] The present invention is a plugging tool designed to solve the above-mentioned technical problems, which is simple in structure, safe and reliable, and can flexibly deal with pipes of different specifications and sizes....
