Abstract
The utility model discloses a fireproof magnetic control electromagnetic valve which comprises a hollow valve body. A magnetism control device is disposed on the excircle of the valve body. A magnetism controlled device is disposed inside the valve body. The magnetism control device comprises a first armature, an annular magnet and a second armature. A first coil and a second coil are respectively disposed on the first armature and the second armature. The magnetism controlled device comprises a limit locking plate positioned in a valve body cavity. A spring is disposed on the limit locking plate. The other end of the spring is connected with a magnetic bracket. A movable magnet is disposed on the magnetic bracket. A seal pad is disposed at the front end of the magnetic bracket. The fireproof magnetic control electromagnetic valve has the advantages that by the electromagnetic coils and the magnets, the movable magnet is not in contact with fuel during opening and closing of a safety valve, normally opening and closing of the seal pad in the valve can be achieved, opening and closing can be achieved by utilizing electric signals, and high safety is achieved; when an application environment is at high temperature, even magnetic force fails, the spring inside the valve can block the outlet of the valve, and secondary occurrence of fuel accidents can be prevented effectively.
Description
Technical field
The utility model belongs to pipeline fluid valve arrangement safety control technology field, relates to the fire prevention such as a kind of gas, liquid automatic-closing mechanism, and especially a kind of energy is by the safety electric magnet valve of the elasticity of spring and the machinery of magnetic picture combination, electromagnetism combined type.
Background technique
Valve or indoor main valve electromagnetism automatic valve used are the up and down plunger valve being separated by diaphragm substantially before existing civil gas stove, and this type of valve is only suitable for being arranged on unlatching, close the effect for emergency switching-off fluid source of pipeline location that movable number of times is few.Sealing is basic to be done to seal for elastomer diaphragm, can cause elastomer diaphragm to strain using for a long time frequently under the situation, does not have the effect of sealing, can cause that serious gas leakage after-explosion causes unnecessary loss of life and property; Kitchen breaking out of fire produces high-temperature ball valve or stopcock can not cut out automatically, after state that valve is opened is on fire because the continuous output of combustion gas causes follow-up dangerous situation, very serious of consequence.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of simple in structure, fire prevention magnetic control solenoid valve that Safety performance is good, can utilize electrical signal to realize the keying of solenoid valve, and then realize telecontrol by the positive and negative voltage that changes its access electromagnetic coil.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of fire prevention magnetic solenoid valve, and its key technology is: it comprises hollow valve body, described valve body cylindrical is provided with magnetic control device, inside is provided with magnetic controlled device;
Described magnetic control device comprises the first armature, is movably sheathed on ring magnet and the second armature on valve outer wall, on described first, second armature, be respectively equipped with the first electromagnetic coil, the second electromagnetic coil, the spacing between described the first armature and the second armature is greater than the thickness of ring magnet;
Described magnetic controlled device comprises and is positioned the endoceliac limit locking pieces of valve, described limit locking pieces is provided with spring, the other end of described spring is connected with magnet carrier, and described magnet carrier is provided with the movable magnet supporting with ring magnet, and the front end of magnet carrier is provided with sealing gasket.
Described valve body one side is provided with suction port, opposite side is provided with air outlet.
The beneficial effect that adopts technique scheme to produce is: the utility model is provided with electromagnetic coil and magnet, and then can utilize magnetic to separate the characteristic of magnetic conduction, while making safety valve switch movable magnet not with contacts fuel gas, sealing gasket utilizes the function of magnetic and the real normal Push And Release of spring in valve, can not only utilize electrical signal to realize opens and closes, and can manually realize keying, safe.The in the situation that of Environmental Conditions generation high temperature, even if magnetic force lost efficacy, the spring of valve internal also can block valve export, cuts off source of the gas, effectively prevents that the secondary of gas accidents from occurring.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Referring to accompanying drawing 1 and accompanying drawing 2, the present embodiment comprises hollow valve body 2, is positioned with magnetic control device, in the chamber of valve body 2, is provided with magnetic controlled device on the outer wall of this valve body 2.
Wherein, described magnetic control device comprises the first armature circle 4 of setting gradually, is movably sheathed on ring magnet 5 and the second armature circle 6 on valve body 2 outer walls, on described first, second armature circle, be respectively equipped with the first electromagnetic coil 3, the second electromagnetic coil 8, the spacing between described the first armature circle 4 and the second armature circle 6 is greater than the thickness of ring magnet 5.
Described magnetic controlled device comprises the limit locking pieces 15 being positioned in valve body 2 chambeies, described limit locking pieces 15 is provided with spring 14, the other end of described spring 14 is connected with magnet carrier 13, described magnet carrier 13 is provided with the movable magnet 11 supporting with ring magnet 5, and the front end of magnet carrier 13 is provided with sealing gasket 11.
Described valve body 2 left sides are provided with suction port 1, right side is provided with air outlet 10(taking Fig. 1 as example).
When this novel use, the Apparatus and method for that can control its positive and negative voltage transitions is a lot, and such as adopting a stabilized power supply and a reverser to realize, needing only it can power, and can realize the forward and reverse switching of electric current.
The present embodiment working procedure is as follows:
Gas or fluid enter from suction port 1, are gone out by air outlet 10.In the time of valve opening, produce homopolarity or heteropole to the first electromagnetic coil 3, the second electromagnetic coil 8 by power-supply controller of electric input electrical signal, promote ring magnet 5, and driving the Sealing and the first armature circle 4 adhesives that are formed by sealing gasket 11, movable magnet 12 and magnet carrier 13, valve is opened in the centre that is now suspended in ring magnet 5 due to the effect movable magnet 12 of magnetic by force Compress Spring 14.
When valve closing, input contrary electrical signal and produce homopolarity or heteropole to the first electromagnetic coil 3, the second electromagnetic coil 8, promote ring magnet 5 and the second armature circle 6 adhesives, Sealing, due to together the fit sealing plane of air outlet end of the double action of magnetic force and spring force, cuts off source of the gas and exports.
This fire prevention magnetic control solenoid valve can also manual-lock or unlatching in realizing electrical signal and cutting out or open.In the time there is no electricity, the manual ring magnet 5 and the first armature circle 4 or the second armature circle 6 of promoting just can be realized and close or open.
In the time that valve environment in the middle of using process is spent height or breaking out of fire, because being subject to high-temperature magnetic, magnet lost efficacy, all the time the sealing plane that promotes black box and air outlet end in the effect of spring 14 elastic force is kept closed, and cuts off the generation of the effective Accident prevention of source of the gas.
