Description
Technical field
The present invention relates to DC electric apparatus field, more particularly to one kind " to play artery with electricity saving function with triode type
The economize on electricity DC electromagnetic valve of circuit occurs for punching ".
Background technology
Solenoid valve (Electromagnetic valve) is a kind of electromagnetic force produced by magnet exciting coil to drive valve
The fluid control device of open and close.
DC electromagnetic valve is the type in solenoid valve, is using widely straight in household electrical appliance and industrial control equipment
Galvanic electricity device.Its main feature is that DC voltage is accessed in magnet exciting coil, the electromagnetic force of driving valve open/close is produced with DC current.
DC electromagnetic valve is mainly made of magnet exciting coil, spool, resetting spring.Fig. 1 a, Fig. 1 b control for DC electromagnetic valve
The schematic diagram of fluid (gas or liquid) switching；Fig. 2 a, Fig. 2 b are that the direct current hydraulic buttery valve in hydraulic test controls " hydraulic oil "
The schematic diagram of flow direction.
With reference to Fig. 1 a：A1, A2 termination logical DC12V, DC24V or other DC voltage (following common names when magnet exciting coil
DC12V, DC24V or other DC voltages are D/C voltage) when, its electromagnetic force produced promotion spool overcomes the resistance of resetting spring
And move down, the piston being connected with spool also moves down therewith, and the DC electromagnetic valve is opened, its " entrance " and " outlet "
Connect.
With reference to Fig. 1 b：When in magnet exciting coil D/C voltage shut-off when, spool loss of excitation power, by resetting spring effect and on
Move, piston also moves up therewith, the DC electromagnetic valve Reset, its " entrance " is turned off with " outlet ".
With reference to Fig. 2 a：When A1, A2 termination of the magnet exciting coil of hydraulic buttery valve lead to D/C voltage, its electromagnetic force produced promotes
Spool overcomes the resistance of resetting spring and moves right, and one to be connected with spool group piston also moves to right therewith, the hydraulic pressure
2 mouthfuls of solenoid valve are just switched on 3 mouthfuls, 1 mouthful with 4 mouthfuls.
With reference to Fig. 2 b：When D/C voltage in the magnet exciting coil of hydraulic buttery valve turns off, spool loss of excitation power, by resetting spring
Act on and move to left, piston also moves to left therewith, and the hydraulic buttery valve Reset, its 1 mouthful is just connect with 2 mouthfuls, 4 mouthfuls with 5 mouthfuls
It is logical.
In conclusion the course of work of DC electromagnetic valve can be divided into " starting ", " holding " Reset three phases：
1st, start：A1, A2 end of magnet exciting coil and D/C voltage are connected, and electromagnetic force promotes valve core movement；
2nd, keep：Spool reaches the position of setting, and magnet exciting coil continues to connect with D/C voltage, and spool continues by electromagnetism masterpiece
With；
3rd, reset：Magnet exciting coil disconnects D/C voltage, spool dead electricity magneticaction and position when returning back to starting.
Aobvious you are clear to, and in start-up period, spool, which must pull against stiction and the elastic force of resetting spring, needs larger electromagnetism
Power effect could move.Corresponding, D/C voltage must provide larger power (hereinafter referred to as starting power) magnet exciting coil
Larger electromagnetic force can be produced, can ensure the movement of spool.
In the stage of holding, spool has reached setting position, and D/C voltage need to only provide less power and (hereinafter referred to as keep work(
Rate) spool can be made to overcome the elastic force of resetting spring and be maintained on setting position.It is corresponding, if D/C voltage still carries at this time
For the power high with start-up period-sample, energy dissipation will be caused and make the meaningless heating of magnet exciting coil！

There are following critical defect：
1st, generate heat：Traditional DC electromagnetic valve generates heat seriously due to keeping power excessive, and magnet exciting coil is burnt because of overheat
The phenomenon ruined also repeated；
2nd, power consumption：Another shortcoming of traditional DC electromagnetic valve is just to maintain the excessive and meaningless power consumption of power, reduces this
Kind power consumption, so that it may obtain the effect of " economize on electricity "；
3rd, it is out of control：After magnet exciting coil fever, its impedance increase, electric current diminishes, and electromagnetic force also reduces therewith, if at this time again
Secondary moving electromagnetic valve, spool will be difficult to reach setting position because electromagnetic force is too small, household electrical appliance or industrial control equipment can therefore and
System is out of control.
The shortcomings that for traditional DC electromagnetic valve, the present invention want Da to target be：
1st, " electronics technological transformation conventional industries are used ", designs that a kind of electronic circuit is as far as possible simple, device used is as far as possible few
, price try one's best it is honest and clean, can make Traditional DC solenoid valve economize on electricity " power save unit "；
2nd, the Traditional DC solenoid valve that " power save unit " can be used for transformation to use online is somebody's turn to do, these DC electromagnetic valves is risen Grade
As " pulsed economize on electricity DC electromagnetic valve "；
3rd, being somebody's turn to do " power save unit " can also be integrated into the DC electromagnetic valve that will be produced, and give birth to the manufacturer of DC electromagnetic valve
