High-intensity magnetic field positioning high-pressure balancing leaking stoppage equipment

Abstract

The invention discloses high-intensity magnetic field positioning high-pressure balancing leaking stoppage equipment which comprises high-intensity direct current permanent-magnet suction discsuction cup capable of being strongly attracted with paramagnetic materials such as a ship hull, a storage tank, a tank car and a petrochemical pipeline, a sealing capsule, a metal housing and a pressure adjustment lead screw. The high-intensity direct current permanent-magnet suction discsuction cup generates or eliminates a high-intensity magnetic field instantly through a 24V control circuit, and the sealing capsule belongs to a flexible braided rubber hollow high pressure resistant expansion body, and is supercharged by solid and liquid glue and nitrogen. The metal housing is used for controlling an expansion direction of the sealing capsule; a pressure adjustment handle drives the lead screw to be connected with the metal housing and has a mechanical pressure adjustment function; the high-intensity direct current permanent-magnet suction discsuction cup can be independently used for the leaking stoppage equipment; or the high-intensity direct current permanent-magnet suction discsuction cups can be combined to be used for the leaking stoppage equipment. The equipment has the advantages that a high-intensity magnetic field force is adjustable, free attracted positioning is achieved, the high-pressure balancing of the sealing capsule is used for blocking medium leakage, and the equipment solves the problems that the existing permanent-magnet leaking stoppage tool cannot change position quickly or block medium undercurrent.

Description

technical field [0001] The invention relates to an emergency rapid pressure regulation and balance plugging equipment for the surface of ship shells, hazardous chemical storage tanks, tank cars, and petrochemical pipelines made of steel and other magnetophilic materials. Background technique [0002] At present, the petrochemical and other hazardous chemical industries are developing rapidly in step with the economy. The pipeline network is dense, the shipping trade, and the tanker transportation volume are increasing. The frequent storage and transportation turnover of the dense pipeline network will inevitably lead to oil, gas and other hazardous chemical leakage accidents. . The medium characteristics of this industry are high-risk and risky. Once a leak is a great threat to the environment, life and property, it needs to be dealt with decisively and effectively. According to the physical and chemical characteristics of the existing tank trucks, pipelines, and medium pre...

AI Technical Summary

Problems solved by technology

[0003] For example, the permanent magnet plugging tools used in the existing plugging methods are relatively primitive, difficult to store and transport, and prone to accidental pull-in collisions. The sealing layer in front of the magnet is not effective enough to make the sealing defect prominent, due to the unreasonable mechanical design Most of them cannot block the leakage of the medium, and have only one-time use value. The difficulty of disassembly after use brings regret to the firefighters and soldiers that the leakage cannot be completely eliminated, which seriously affects the process of accident disposal.

Practical lessons from many cases have taught us that in the process of rescue of hazardous chemicals, especially the leakage of positive pressure containers, complete elimination of leakage is a necessary condition for the success of rescue and plugging, especially the leakage of poisonous gas, liquefied petroleum gas, compressed natural gas, fuel oil and crude oil Be sure to use reliable tools and equipment that can completely eliminate leaks, otherwise it will be a waste of time and money, delay the fighter plane, and bring greater safety hazards to the accident disposal
