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 ha

Example Embodiment

[0052] Example 1

[0053] A leakage point was found in the iron 20mm pipe of a certain production equipment. The medium at this leakage point is warm, pressurized, flammable, and has a certain degree of acid corrosion. The medium is in a flowing state and cannot be stopped.

[0054] Use 3-5 pieces of 50mm*50mm*50mm neodymium-iron-boron strong magnet blocks at the leakage point of the iron 20mm pipeline to produce dots, faces, and strips (or other shapes) to form a strong magnetic guide. Area (leak point).

[0055] Combine a certain proportion of metal powder (magnetically effective stainless iron powder 30%-70%), one or more organic synthetic resin glue 20-50% (weight), and one or more non-drying glue produced soft Viscous glue, using high pressure and strong injection technology or with the flowing medium inside the pipeline, enters the leakage point of the leaking pipeline, and is adsorbed inside the pipeline leakage point to form a centralized sealing glue. The centralized sealin...

Example Embodiment

[0059] Example 2

[0060] An electromagnet is used to form a strong magnetic field at the leakage point of iron 30-40mm iron or synthetic resin pipes and larger iron or synthetic resin containers, and the magnetic field strength unit is 12000GS. With regard to the shape of the leakage point, a dot shape, a surface, a long linear shape (or other shapes) are generated to form a strong magnetic guide area (leak point).

[0061] The soft viscous adhesive described in Example 1 is used to use high-pressure injection technology or enter the leaking pipeline or container leakage point together with the flowing medium in the pipeline or container, and is adsorbed inside the pipeline or container leakage point to form a centralized sealing glue. The concentrated sealing glue is attracted and fixed by the magnetic orientation of a strong magnetic field, forming a plugging of the leakage point.

[0062] Others are the same as in Example 1.

[0063] After the leaking point colloid is successfull...

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...
