Description
Technical field
The utility model relates to a kind of solenoid valve, the low-power consumption electromagnetic valve that particularly a kind of carrier state signal is exported, and while there is accidental gas leakage as pipeline gas, the solenoid valve of the gas emergency closing control that can be used in conjunction with gas sensing member.
Background technique
The solenoid valve that solenoid valve generally has solenoid actuated to open, the solenoid valve that has pulsed voltage to drive, also the solenoid valve that has electromagnet unidirectional drive, the solenoid valve of solenoid actuated switches on for a long time need to when operation electromagnetic coil and just can work, and energy consumption is large, coil easily generates heat; The solenoid valve that pulsed voltage drives when opening or closing only need to one of electromagnetic coil forward or backwards pulsed voltage can open or close, very power saving, coil does not generate heat; The solenoid valve of electromagnet unidirectional drive adopts mechanical lock buckle to realize and opens, and hand tripping resets, power saving, complex structure.
Existing gas emergency closing control solenoid valve mostly is the solenoid valve of pulsed voltage unidirectional drive, and be hand reset, be very power saving, coil does not generate heat yet, if driving circuit for electromagnetic valve could not cut off coil power supply yet, also can make electromagnetic valve coil heating, because the number of turn of this coil is few, internal resistance is little, very easily heating, even burn, give fuel gas pipeline safety influenced.
Gas emergency closing control solenoid valve also has a realistic problem that there is no state position signal, solenoid valve in use, still do not know that whether solenoid valve, in opening or closed condition, when especially control circuit breaks down, more needs to understand solenoid valve in safety shut-off state.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of safety type gas emergency solenoid valve that do not generate heat is provided, can not generate heat giving the long-time energising of solenoid valve, avoid fuel gas pipeline to cause safely secondary to threaten, to solenoid valve, increase the state signal output of opening or closing, the indication of solenoid valve state signal can be provided, also can send alarm signal by warning circuit.
The technical scheme in the invention for solving the above technical problem is: a kind of safety type gas emergency solenoid valve that do not generate heat, comprise by case, pull-button, electromagnetic coil, secured core, movable core, ∏ shape iron is gripped, magnet steel, thrust spring, spool, pull-button barrier film, push rod barrier film, electric capacity wink circuit passband, copper valve body, dry reed-pipe and lighting outlet form, described electromagnetic coil is by being wound with coil on a plastic skeleton seated, top is provided with secured core, in coil rack, be provided with the movable core of two end pull-button bars and spool push rod, at coil, being outside equipped with the ∏ shape iron that lower end is placed with magnet steel grips, formed an Electromagnetic Drive part, it is characterized in that electromagnetic coil string has the electric capacity wink circuit passband that prevents long heating power, in case outside, the dry reed-pipe as spool state signal is installed.
Compared with prior art, concrete advantage of the present utility model is: (1), because string on the coil of solenoid valve has an electric capacity wink circuit passband, the large electric current effectively having limited after pulsed voltage acting passes through coil, especially can prevent that control circuit from breaking down continues to electromagnetic valve coil power supply and generates heat, avoid coil heating to burn and have an accident, making solenoid valve safer in use; (2) dry reed-pipe, being arranged on outside case utilizes movable core to slide up and down magnet short-cut path and the magnetic open circuit to magnetic circuit formation, realize the state signal output of spool, can know that whether solenoid valve is in closed condition, reliability is provided to the actual use of gas emergency closing control solenoid valve.

Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are further described.
As shown in Figure 1, the ∏ shape iron that has interior lower end to be provided with two blocks of magnet steel (10) in case (19) is gripped (17), being arranged on top is plugged with secured core (14) and is wound with outside seated (7) coil rack (8) of coil (12), in coil rack (8), there are two ends to be provided with the movable core (13) of pull-button bar (15) and spool push rod (6), the pull-button barrier film (16) that grip on (17) through ∏ shape iron pull-button bar (15) upper end is connected with the pull-button (23) on case (19), the spool push rod (6) of movable core (13) is connected with the upper clamp (3) of thrust spring (4) and rubber spool (2) through push rod barrier film (5), electric capacity wink, circuit passband was serially connected with a wherein lead-in wire of coil (12) by electrolytic condenser (11) and discharge resistance (9) and after connecing, by lighting outlet (24), being connected to case again draws outside wire casing (21), by above-mentioned Component composition in case (19), expose to the greatest extent push rod barrier film (5) and thrust spring (4) and rubber spool (2) and be positioned over copper valve body (1) upper end, with 4 screw tightenings, fix, as shown in Figure 2, case (19) outer side surface has a vertical groove (20), the dry reed-pipe (18) that is welded with lighting outlet (22) is filled in this groove, form the state signal sensor of solenoid valve.
During use, as shown in Figure 3, because ∏ shape iron is gripped (17) lower end inner side and is had magnet steel (10), when manually when carrying on pull-button (23), movable core (13) in coil rack (8) also with on move to secured core (14), the magnetic line of force in figure (X) forms closed magnetic loop, form larger magnetic force and overcome thrust spring (4) active force, that rubber spool (2) is in opening state, now at ∏ shape iron, grip the magnetic field diffusion minimum of (17) lower end, therefore dry reed-pipe (18) can not get enough magnetic force, the contact of breaking inner represents solenoid valve opening state signal, as Fig. 4, when giving (12) direct impulse voltages of electromagnetic valve coil, because ∏ shape iron is gripped (17) lower end inner side and is had the polarity of setting of magnet steel (10) contrary with electromagnetic valve coil, this direct impulse voltage is equivalent to offset the active force of magnet steel (10) to movable core (13), do not overcome thrust spring (4) active force and oppositely move, make the movable core secured core that speeds away, closed magnetic loop is moved to end, spool is acted on the valve opening of the interior center of copper valve body (1) by thrust spring (4), make valve closing, simultaneously, the magnetic line of force in figure (Y) becomes magnetic disperse state, do not become magnetic loop, and dry reed-pipe (18) obtained diffusion magnetic field make inner contact be enough to closure, represent closed electromagnetic valve state signal.
When driving the control circuit of solenoid valve to break down, in the time of can not cutting off the electricity supply in time, capacitor in electric capacity wink circuit passband can only pass through short time pulsed voltage, only there is very little electric current to pass through, therefore electromagnetic valve coil can not generate heat and burn, memory voltage when pending fault is eliminated rear deenergization on capacitor discharges by being attempted by the discharge resistance of capacitor two ends, to guarantee next solenoid-driven use.
