Abstract
The invention discloses a permanent magnetism switch. The switch is provided with a magnetic base, and the magnetic base is formed in a way that a ferromagnetic material clamps a non-magnetic material; a non-magnetic material part is positioned in the middle of a vertical direction of the magnetic base, a center hole in the vertical direction is formed in the middle of the magnetic base, the wall of the center hole is composed of the ferromagnetic material and the non-magnetic material, and the same materials are relatively arranged; the center hole is internally provided with a rotatable core column, the core column is made of a permanent-magnet material, a magnetic field direction of the core column is distributed by being perpendicular to the axis of the center hole, and the magnetic field of the core column is rotated in a horizontal direction; and when the magnetic field of the core column faces a ferromagnetic material part, the magnetic attraction force is strengthened after the magnetic base is magnetized, when the magnetic field of the core column faces the non-magnetic material part, the magnetic field of the core column is broken, and the magnetic attraction of the magnetic base is weakened. The magnetic line of the permanent magnetism switch is closed, the adsorption capacity is strong, the magnetic force is small before seal under pressure is carried out, the localization is easy, and the permanent magnetism switch can be regulated to a small adsorption capacity state in disassembly, thus being easy to disassemble.
Description
Technical field
The present invention relates to a kind of permanent-magnetic switching, be specifically related to a kind of adsorption force of permanent magnet that utilizes and stationary device realized to other objects, the size of this device its adsorption force adjustable.
Background technique
Along with the fast development of national economy, movable vessel has been widely used in (comprising truck tank, Railway tank car, long-tube trailer, tank container and bundled tube shipping container etc.) the strange land transport of industrial fluids medium.Due to movable vessel have that useful load is large, transportation means flexibly and the feature such as cost of transportation is cheap, can carry out highway, railway, water route transport or realize the through transport of these means of transportation, develop rapidly in process in national economy and play very important effect.
The medium overwhelming majority of movable vessel accumulating is inflammable, explosive, harmful liquid gas or cryogen, transportable pressure vessel is except bearing interior pressure or external pressure effect under steam, also can be subject to continually impacting, shaking, the particularly generation of collision and traffic accident, the leakage of splendid attire fluid can be caused, cause serious accident, bring high risks to national wealth and people's life, social influence is extremely bad.Therefore, how easy, quick, reliably, safely eliminate movable vessel leakage accident, be that on-line pressure sealant those skilled in the art need the urgent technical problem solved.
At present, magnetic-type seal arrangement is usually adopted to carry out quick pressurize sealing to the movable vessel occurring to leak.The attraction force that magnetic-type seal arrangement directly utilizes permanent-magnet material to produce, to realize movable vessel on-line pressure sealant, does not generally adopt electromagnet, because electromagnet very easily producing sparkover when being energized, running into fire good and can cause huge disaster.Permanent-magnet material is adopted substantially to achieve the effect of security seal, but ubiquity three problems: and one is that magnetic force is not enough, and two is not easily locate, and three is not quick detachable.All above deficiency can be found in following patent of having declared.
A kind of high-pressure strong-magnetization on-line pressure sealant device is described in Chinese utility model patent (patent No.: ZL200920218345.9), several magnetic attracting device ring is established and is fixed on the outward edge of seal closure opening by this on-line pressure sealant device, magnetic attracting device comprises a box body, permanent magnet is put in box body, the port iron plate that box body contacts container to be sealed seals, permanent magnet itself is fixed with a dwang, dwang one end is positioned at box portion outside, the adjustment of permanent magnet magnetic field direction can be realized by rotating this dwang, thus the size of control cincture pressure sealing device adsorption force.But this magnetic attracting device only employs a magnetic pole of permanent magnet, and the magnetic line of force does not form closed magnetic circuit, not enough to magnetic attraction during seal of vessel.
Describe a kind of strong tape pressure sealing device in Chinese utility model patent (patent No.: ZL201020623909.X) and regulate the independent control of its magnetic force size, its independent control is provided with cover body, cover body roof is provided with a connecting rod, the connecting rod one end being positioned at cover body is fixed with magnet piece, the connecting rod one end be positioned at outside cover body is provided with eccentric cam, the adjustment of magnet piece and container wall distance to be sealed can be realized by rotating eccentricity cam, thus control the size of strong tape pressure sealing device adsorption force, this independent control also has a kind of similar structure, connecting rod is threaded with magnet piece, also the fast adjustment with container wall distance to be sealed of magnet can be realized by swivel link itself.But this on-line pressure sealant device still exists above-mentioned defect, namely only make use of a magnetic pole of permanent magnet, the magnetic line of force does not form closed magnetic circuit, magnetic attraction is not enough, if the magnetic direction of magnet piece and connecting rod axis vertical distribution, there is again adjustable range short, magnetic attraction changes unconspicuous defect.
Describe the strong magnetic of a kind of circular cap type in Chinese utility model patent (patent No.: ZL200720095409.1) to speedily carry out rescue work on-line pressure sealant instrument, the sealed body of this on-line pressure sealant instrument is made up of ball column-shape showering and circular formwork, its shape is in circle shape for hat, magnetized block is inlaid with and every magnet frame in circular formwork, magnetized block is permanent magnet, during the sealing of this execution of instrument, because the magnetic force of permanent magnet just exists, so not easily locate, regulate absorption position difficulty on the wall, unloading process is also comparatively loaded down with trivial details, or adopt energising demagnetization, or utilize leverage to be prized from seal container., there is above-mentioned defect equally in the seal arrangement that the patent that technological scheme is similar also has a kind of rubber introduced in Chinese invention patent (patent No.: ZL201010108746.6) to be combined with ferromagnetic material.
