Description
Technical field
The present invention relates to Low Voltage Electrical Apparatus, particularly relate to a kind of " there is the energy-saving type alternating current electromagnetic valve of triode type switching pulse circuit for generating " with the function of saving power.
Background technique
Solenoid valve (Electromagnetic valve) is that a kind of electromagnetic force relying on field coil to produce is to drive the fluid control device of valve open/close.
Alternating current electromagnetic valve is the type in solenoid valve, is the low-voltage electrical apparatus applied in household electric appliance and industrial control equipment widely.Be characterized in field coil incoming transport voltage, produce the electromagnetic force driving valve open/close with alternating current (a.c.).
Alternating current electromagnetic valve is primarily of field coil, spool, Returnning spring composition.Fig. 1 a, Fig. 1 b are the schematic diagram of alternating electromagnetic valve controls fluid (gas or liquid) switching; Fig. 2 a, Fig. 2 b are the schematic diagram that the AC hydraulic electromagnetic valve " hydraulic oil " in hydraulic equipment flows to.
Composition graphs 1a: when A1, A2 termination of field coil leads to AC220V, AC110V or AC380V voltage (being generally called AC220V, AC110V or AC380V is below AC voltage), its electromagnetic force produced promotes spool and overcomes the resistance of Returnning spring and move down, the piston be connected with spool also moves down thereupon, described alternating current electromagnetic valve is opened, and its " entrance " and " outlet " are connected.
Composition graphs 1b: when the AC voltage in field coil turns off, spool loss of excitation power, moves on by the effect of Returnning spring, piston also with on move, described alternating current electromagnetic valve " resets ", its " entrance " and " outlet " turn off.
Composition graphs 2a: when A1, A2 termination of the field coil of hydraulic buttery valve leads to AC voltage, its electromagnetic force produced promotes spool and overcomes the resistance of Returnning spring and move right, the one group of piston be connected with spool also moves to right thereupon, and 2 mouthfuls of described hydraulic buttery valve are just switched on 4 mouthfuls with 3 mouthfuls, 1 mouthful.
Composition graphs 2b: when the AC voltage in the field coil of hydraulic buttery valve turns off, spool loss of excitation power, move to left by the effect of Returnning spring, piston also moves to left thereupon, described hydraulic buttery valve " reset ", and its 1 mouthful is just switched on 5 mouthfuls with 2 mouthfuls, 4 mouthfuls.
In sum, the working procedure of alternating current electromagnetic valve can be divided into " promotion ", " maintenance " " reset " three phases:
1, promote: A1, A2 end and the AC Voltage On state of field coil, electromagnetic force promotes valve core movement;
2, keep: spool arrives the position of setting, field coil continues and AC Voltage On state, and spool continues by electromagnetic force and remains on the position of setting;
3, reset: field coil disconnects AC voltage, spool dead electricity magnetic force and resetting.
Aobvious you easily see, in the promotion stage, the elastic force that spool must overcome stiction and Returnning spring needs larger electromagnetic force to move.Corresponding, AC voltage must provide higher voltage, larger power (hereinafter referred to as promotion power) field coil could produce larger electromagnetic force, can ensure the motion of spool.
In the maintenance stage, spool arrives desired location, and the elastic force that need only overcome Returnning spring just can remain on desired location.Corresponding, if now field coil still pass to promotion stage-alternating voltage that sample is high, will energy dissipation be caused and make field coil without the intensification of favour!
Owing to promoting all to pass to identical alternating current voltage (such as AC220V) with maintenance stage field coil, therefore there is following critical defect in traditional alternating current electromagnetic valve:
1, generate heat: front already described, in promotion and maintenance stage, traditional alternating current electromagnetic valve all passes to identical alternating voltage (such as AC220V), and therefore, heating is serious, and the phenomenon that field coil burns because of overheated also occurs repeatedly;
2, power consumption: the energy of traditional alternating current electromagnetic valve heating inputs electric energy in field coil exactly, another shortcoming that this kind of harmful heating brings is exactly meaningless power consumption.Reduce this power consumption, just can obtain the effect of " economize on electricity ";
Therefore and system is out of control 3, out of control: after field coil heating, its impedance increases, and electric current diminishes, and electromagnetic force also can not promote spool to desired location thereupon reduction, household electric appliance or industrial control equipment can.
For the shortcoming of traditional alternating current electromagnetic valve, the present invention want Da to target be:
1, " by electronics technical innovation conventional industries ", design a kind of electronic circuit as far as possible device simple, used few, price is as far as possible honest and clean, that conventional AC solenoid valve can be made to economize on electricity " power save unit " as far as possible;
2, " power save unit " should can be used for transforming the online conventional AC solenoid valve used, making these alternating current electromagnetic valves rise Grade becomes and has electricity saving function alternating current electromagnetic valve;
3, should " power save unit " also accessible site in the alternating current electromagnetic valve that will produce, make the MANUFACTURER of alternating current electromagnetic valve produce novel have electricity saving function " energy-saving type alternating current electromagnetic valve " integrated with " power save unit ".
