Abstract
The utility model relates to a self holding electromagnetic valve, which comprises a fixed magnetic armature, a magnetic moving valve core, a coil, a valve body, a polarity reversed changing circuit, etc. The utility model can be opened and closed by being electricified for a short time, and the state of the valve can be held after the power is cut off. The utility model has the advantages of convenient operation, reliability, no heat generation and energy saving.
Description
The utility model is a kind of electromagnetic valve that can be widely used in industrial gas, liquid, line transportation control.
Solenoid valve has following several at present:
One, general solenoid valve comprises alternating current electromagnetic valve, DC electromagnetic valve.Have in these solenoid valves: the normal close type solenoid valve when keeping opening the valve state, keep energising, until closing valve always; Normal-open electromagnetic valve when keeping closing the valve state, keep energising, until driving valve always.Thereby the power consumption height of general solenoid valve, coil is easily heating not only, and long-time energising is easily burnt.
Two, mechanical retaining electromagnetic valve, after this solenoid valve is opened, during outage by mechanical mechanism maintaining valve state.State that can maintaining valve during the outage of this valve, but the complicated in mechanical structure of its state retaining mechanism, the cost height.
Purpose of design of the present utility model is to provide a kind of can overcome existing solenoid valve shortcoming, and outage can keep valve state, and simple in structure, cost is low, the electromagnetic valve that reliability is high.
Purpose of design of the present utility model is achieved in that
The movable valve plug of solenoid valve, make by permanent magnet, be bumped into one at the top of loop sleeve and decide armature by what the electrical pure iron material was made, when opening of valves, electric current flows into coil from valve coil one end, and the magnetic field polarity that coil produces is opposite with the magnetic field polarity of the moving magnetic core of magnetic, there is a natural attraction between the sexes, the magnetic movable valve plug is sucked coil, drive jam pot cover, make valve opening by the movable valve plug loop bar; When outage, movable valve plug is inhaled by its magnetic action and is being decided on the armature, keeps the state of opening of valve when realizing outage.When electric current when the other end of valve coil flows into, the magnetic field polarity that coil produces is identical with the magnetic field polarity of magnetic movable valve plug, the same sex is repelled each other, and the magnetic movable valve plug is broken away from decide armature, by movable valve plug loop bar drive jam pot cover, makes valve closing; During outage because the elastic force effect of spring, but the maintaining valve door closure state.Valve opening needs only energising hundreds of millisecond by several seconds with closing, and its state can keep voluntarily at ordinary times.Because solenoid valve adopts direct current supply, thereby does not exchange noise.
The utility model is because of only needing to change the moving armature of general solenoid valve into permanent magnet, loop sleeve is tumbled in permeability magnetic material (as electrical pure iron), and other structure of valve need not change, so structure is simple especially, do not have complex mechanical construction simultaneously, thereby original manufacturing mechanism and part major part can both be used.
The utility model concrete structure is provided by following enforcement example and accompanying drawing 3 thereof, and Fig. 1, Fig. 2 are the self-holding electromagnetic valves of two kinds of different structure forms, and Fig. 3, Fig. 4 are the typical control circuits of self-holding electromagnetic valve.
Below in conjunction with Fig. 1, describe details and working condition in detail according to the concrete device of the solenoid valve that the utility model proposes.
This electromagnetic valve structure is: a valve upper cover (2) is arranged on the valve body (1), loop sleeve (3) is installed on the valve upper cover (2), coil (4) is enclosed within on the loop sleeve (3), be installed in the hood-shaped magnetic circuit (5), decide armature (6) and be set in the interior top of loop sleeve (3), the magnetic movable valve plug (7) that can move up and down in loop sleeve (3) built-in, the magnetic movable valve plug is set in the movable valve plug loop bar (8), there are a jam pot cover (9) and valve insert (10) in its lower end, by wearing pin (11) moving valve pocket bar of magnetic and jam pot cover are linked up, spring (12) is enclosed within on the magnetic movable valve plug loop bar, when spring is closed at jam pot cover, because the elastic force effect of spring makes jam pot cover end fluid.
Hood-shaped magnetic circuit (5), decide armature (6) and all made by permeability magnetic material, common adoptable material is an electrical pure iron.Loop sleeve (3) and movable valve plug loop bar (8) can adopt non-magnetic stainless steel, copper, plastic or other material according to different needs.Magnetic movable valve plug (7) can use various permanent magnet material, preferably adopts the highest rare earth permanent-magnetic material of magnetic energy volume.Movable valve plug loop bar (8) can adopt to be worn pin articulated or alternate manner and jam pot cover and links.
Fig. 2 is the structural drawing of another kind of self-holding electromagnetic valve, valve body (1) is installed in, on the valve seat (2), line chart (4) is installed in the loop sleeve (3), hood-shaped magnetic circuit (5) in, decide armature (6) and be embedded in the top of hood-shaped magnetic circuit, in hood-shaped magnetic circuit, be equipped with a magnetic movable valve plug (7) that can move up and down, the magnetic movable valve plug is set in the movable valve plug loop bar (8), and there is a jam pot cover (9) its lower end, and valve insert (10) is worn pin (11) movable valve plug loop bar and jam pot cover are linked up, spring (12) is installed between movable valve plug loop bar and the jam pot cover, and this principle is suitable for the solenoid valve of various structures.
Fig. 3 is the control circuit figure of self-holding electromagnetic valve, D among the figure
1-D
4Be rectifier lamp, a, b are ac input end, and b, c are dc output end, b is anodal, and c is a negative pole, and k is the double-pole-double-throw switch that meta is arranged, when switch was thrown the A end, anodal and valve coil top linked, and negative pole and coil end link, the magnetic field polarity that coil produces is opposite with the magnetic field polarity of magnetic movable valve plug, and movable valve plug is sucked in the sleeve, and inhales deciding on the armature in sleeve, make valve open, during outage, the magnetic movable valve plug just remains on to be decided on the armature, makes valve keep opening state; When needs close valve, switch is thrown the B end, the end of positive source and valve links, the negative terminal of power supply and the top of valve link, magnetic field polarity that coil produces and magnetic movable valve plug magnetic field polarity make the armature of deciding in the magnetic movable valve plug disengaging loop sleeve, during outage together, under the effect of spring force, make valve keep closed condition.
The open and close controlling circuit of valve can use the double-pole-double-throw switch of meta, can use relay, also can use electronic circuit.For example in my automatic charging gas meter patent, just be to use electronic circuit to realize the open and close controlling of valve.
Main feature of the present utility model is:
1, the top of loop sleeve (3) is bumped into one and is difficult for magnetizedly deciding armature (6) by what permeability magnetic material was made;
2, magnetic movable valve plug (7) is made of permanent magnet material.
Main advantage of the present utility model is:
1, reliability height.Simple in structure, low cost of manufacture.
2, coil does not generate heat, energy saving.
