Magnetic attraction leakage stopping method

Abstract

A magnetic attraction leakage stopping method is used for pressured leakage stopping of pipelines and containers. The magnetic attraction leakage stopping method is characterized in that a large-power electromagnet or strong magnet is used for forming a powerful magnetic field at the leakage points of the pipelines and the containers, soft and sticky glue containing metal powder is poured in the leakage points or jointly enters the leakage points of the leakage pipelines and the leakage containers along with flow media in the pipelines and the containers and is adsorbed in the leakage points of the pipelines and the containers, centralized blocking glue is formed and is fixed through magnetic orientation attraction of the powerful magnetic field, and blocking of the leakage points is formed. The problems that due to the dirty contact face, the glue is not powerful in bonding force, is washed out and is in failure during ejection, drip leakage and flowing outside the leakage points and pressured leakage stopping are solved.

Description

technical field [0001] The present invention relates to a plugging method, in particular, the present invention relates to a magnetic attraction plugging method, which is suitable for seepage in metallurgy, chemical industry, pipelines, containers, leak plugging under pressure, construction, deep pools, etc. The leak is blocked. Background technique [0002] So far, in the normal production and operation of equipment, containers, flanges, pipes, valves and other parts, especially pipes, are very common due to the deterioration of the material of the equipment itself, the harsh working environment and external force factors. On the other hand, because the leaked medium is basically in a warm, pressurized, flammable, sour liquid state or in a state of spraying, dripping, and flowing, the production cannot be stopped or shut down during treatment, which often brings serious losses to production. [0003] Generally, the pipes and containers of large iron and steel enterprises a...

Problems solved by technology

[0020] However, the inevitable disadvantage of the above method is that when the leakage point of the pipeline and container is sprayed outward, dripping, flowing, and working under pressure plugging, there will inevitably be oil, water, dust particles on the surface of the leakage point, etc., which will affect the adhesion fastness. Dirty objects, and the colloid itself has time requirements for curing and the bonding surface must have a clean surface, which will easily cause the leakage point sealing glue to be washed away by the leaking pressurized medium due to weak adhesion, resulting in failure of sealing and failure. Although the plugging effect of coating and infiltration technology is good, the plugging technology is complicated due to the colloidal dispersion medium and the leakage point is long and slit-shaped, and there are difficulties in construction.
