Description
Technical field
The present invention relates to DC electric apparatus field, particularly relate to one and have electricity saving function " there is the economize on electricity DC electromagnetic valve of triode type starting pulse circuit for generating ".
Background technique
Solenoid valve (Electromagneticvalve) is that a kind of electromagnetic force relying on field coil to produce is to drive the fluid control device of valve open/close.
DC electromagnetic valve is the type in solenoid valve, is the DC electric apparatus applied in household electric appliance and industrial control equipment widely.Be characterized in field coil, accessing VDC, producing the electromagnetic force driving valve open/close with direct current (d.c.).
DC electromagnetic valve is primarily of field coil, spool, Returnning spring composition.Fig. 1 a, Fig. 1 b are the schematic diagram of direct solenoid valve controls fluid (gas or liquid) switching; Fig. 2 a, Fig. 2 b are the schematic diagram that direct current hydraulic buttery valve control " hydraulic oil " in hydraulic equipment flows to.
Composition graphs 1a: when A1, A2 termination of field coil leads to DC12V, DC24V or other VDC (be generally called DC12V, DC24V below or other VDC are D/C 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 DC electromagnetic valve is opened, and its " entrance " and " outlet " are connected.
Composition graphs 1b: when the D/C 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 DC 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 D/C 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 D/C 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 DC electromagnetic valve can be divided into " starting ", " maintenance " " reset " three phases:
1, start: A1, A2 end of field coil is connected with D/C voltage, and electromagnetic force promotes valve core movement;
2, keep: spool arrives the position of setting, field coil continues to connect with D/C voltage, and spool continues by electromagnetic force;
3, reset: field coil disconnect D/C voltage, spool dead electricity magnetic force and return back to initial time position.
Aobvious you easily see, at starting period, the elastic force that spool must overcome stiction and Returnning spring needs larger electromagnetic force to move.Corresponding, D/C voltage must provide larger power (hereinafter referred to as starting power) field coil could produce larger electromagnetic force, can ensure the motion of spool.
In the maintenance stage, spool arrives desired location, and D/C voltage only need provide less power (hereinafter referred to as maintenance power) spool just can be made to overcome the elastic force of Returnning spring and remain on desired location.Corresponding, if now D/C voltage still provides the power high with starting period-sample, will energy dissipation be caused and the intensification making field coil meaningless!
Traditional DC electromagnetic valve due to starting power almost identical with maintenance power, therefore, because keeping power excessive and there is following critical defect:
1, generate heat: traditional DC electromagnetic valve is generated heat serious owing to keeping power excessive, the phenomenon that field coil burns because of overheated also occurs repeatedly;
2, power consumption: another shortcoming of traditional DC electromagnetic valve is exactly the power consumption keeping power excessive and meaningless, reduces 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 reduces thereupon, if now again play moving electromagnetic valve, spool will be difficult to because electromagnetic force is too little arrive desired location, and household electric appliance or industrial control equipment can.
For the shortcoming of traditional DC 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 Traditional DC solenoid valve can be made to economize on electricity " power save unit " as far as possible;
2, should " power save unit " can be used for transforming the online Traditional DC solenoid valve used, making these DC electromagnetic valve rise Grade becomes " pulsed economize on electricity DC electromagnetic valve ";
3, should " power save unit " also accessible site in the DC electromagnetic valve that will produce, the MANUFACTURER of DC electromagnetic valve is produced novel " pulsed economize on electricity DC electromagnetic valve " integrated with " power save unit ".
