Description
Technical field
The utility model relates to a kind of permanent-magnetic switching, is specifically related to a kind of adsorption force of permanent magnet of utilizing other objects are realized stationary device, and this device can be regulated the size of its adsorption force.
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 transportation of industrial fluids medium.Due to movable vessel has that useful load is large, transportation means flexibly and the characteristics such as cost of transportation is cheap, can carry out the transportation in highway, railway, water route or realize the through transport of these means of transportation, develop rapidly in national economy and play very important effect in process.
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, can cause the leakage of splendid attire fluid, cause serious accident, bring very big harm for national wealth and people's life, social influence is extremely bad.Therefore, how easy, quick, eliminate the movable vessel leakage accident reliably, safely, be that field of sealing technology technician with pressure needs the urgent technical problems that solve.
At present, usually adopt magnetic-type seal arrangement to carry out the quick pressurize sealing to the movable vessel that occurs to leak.The attraction force that magnetic-type seal arrangement directly utilizes permanent-magnet material to produce realizes movable vessel band means of press seals, does not generally adopt electromagnet, because electromagnet very easily produces sparkover when energising, runs into fire good and can cause huge disaster.Adopt permanent-magnet material substantially to realize the effect of security seal, but three problems of ubiquity: the one, magnetic force is not enough, and the 2nd, be difficult for the location, the 3rd, not quick detachable.All can find above deficiency in following patent of having declared.
Chinese utility model patent (the patent No.: introduced a kind of high-pressure strong-magnetization band pressure sealing device ZL200920218345.9), this is established several magnetic attracting device rings and be fixed on the outward edge of seal closure opening with pressure sealing device, magnetic attracting device comprises a box body, put into permanent magnet in box body, the port of box body contact container to be sealed seals with iron plate, permanent magnet itself is fixed with a dwang, dwang one end is positioned at the box body outside, can realize the adjusting of permanent magnet magnetic field direction by rotating this dwang, thereby control the size with the pressure sealing device adsorption force.But this magnetic attracting device has only used a magnetic pole of permanent magnet, and the magnetic line of force does not form closed magnetic circuit, and during to seal of vessel, magnetic attraction is not enough.
Chinese utility model patent (the patent No.: introduced a kind of strong tape pressure sealing device ZL201020623909.X) and regulated the independent control of its magnetic force size, its independent control is provided with cover body, pass the cover body roof and be provided with a connecting rod, connecting rod one end that is positioned at cover body is fixed with magnet piece, be positioned at outer connecting rod one end of cover body and be provided with eccentric cam, can realize the adjusting of magnet piece and container wall distance to be sealed by the rotating eccentricity cam, thereby 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 can realize magnet soon and the adjusting of container wall distance to be sealed by rotation connecting rod itself.But still there is defects in this band pressure sealing device, has namely only utilized a magnetic pole of permanent magnet, and 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 exist again adjustable range short, magnetic attraction changes unconspicuous defective.
Chinese utility model patent (the patent No.: introduced the strong magnetic of a kind of circular cap type sealing tool with pressure of speedily carrying out rescue work ZL200720095409.1), the sealed body of this sealing tool with pressure is comprised of ball column-shape showering and circular formwork, its shape is round shape for hat, be inlaid with magnetized block in circular formwork and every magnet frame, magnetized block is permanent magnet, during this execution of instrument sealing, because the magnetic force of permanent magnet just exists, so be difficult for the location, be adjusted in the absorption position difficulty on container wall, unloading process is also comparatively loaded down with trivial details, or employing energising demagnetization, or utilize leverage that it is prized from seal container.The similar patent of technological scheme also has Chinese utility model patent, and (patent No.: there is defects equally in the seal arrangement that a kind of rubber of introducing ZL201010108746.6) is combined with ferromagnetic material.
