Description
Technical field
There is electricity saving function " started with integrated circuit type the present invention relates to DC electric apparatus field, more particularly to one kind
The economize on electricity DC electromagnetic valve of pulse generating circuit ".
Background technology
Magnetic valve (Electromagnetic valve) is a kind of electromagnetic force of dependence magnet exciting coil generation to drive valve
The fluid control device of open and close.
DC electromagnetic valve is the type in magnetic valve, is straight using widely in household electrical appliance and industrial control equipment
Flow electrical equipment.It is characterized in accessing DC voltage in magnet exciting coil, the electromagnetic force for driving valve open/close is produced with DC current.
DC electromagnetic valve is mainly made up of magnet exciting coil, valve element, back-moving 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 the direct current hydraulic buttery valve control " hydraulic oil " in hydraulic test
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 valve element overcomes the resistance of back-moving spring
And move down, the piston being connected with valve element is also moved down therewith, and described 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, valve element loss of excitation power, by back-moving spring effect and on
Move, piston is also moved up therewith, described 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 is promoted
Valve element overcomes the resistance of back-moving spring and moved right, and one be connected with valve element group piston is also moved to right therewith, described hydraulic pressure
2 mouthfuls of magnetic 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 is turned off, valve element loss of excitation power, by back-moving spring
Act on and move to left, piston is also moved to left therewith, described hydraulic buttery valve RESET, its 1 mouthful is just connect with 2 mouthfuls, 4 mouthfuls with 5 mouthfuls
It is logical.
In summary, 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：Valve element reaches the position of setting, and magnet exciting coil continues to connect with D/C voltage, and valve element continues by electromagnetism masterpiece
With；
3rd, reset：Position when magnet exciting coil disconnects D/C voltage, valve element dead electricity magneticaction and returns back to starting.
Aobvious you are clear to, in start-up period, and valve element, which must pull against stiction and the elastic force of back-moving spring, needs larger electromagnetism
Power effect could be moved.Corresponding, D/C voltage must provide larger power (hereinafter referred to as starting power) magnet exciting coil
Larger electromagnetic force can be produced, the motion of valve element can be ensured.
In the stage of holding, valve element has reached setting position, and D/C voltage need to only provide less power and (hereinafter referred to as keep work(
Rate) valve element can be made to overcome the elastic force of back-moving spring and be maintained on setting position.It is corresponding, if now D/C voltage is still carried
For the power high with start-up period-sample, energy dissipation will be caused and make the meaningless heating of magnet exciting coil！
Traditional DC electromagnetic valve due to starting power with keep power it is almost identical, therefore, because keep power it is excessive and
There is following critical defect：
1st, generate heat：Traditional DC electromagnetic valve generates heat seriously due to keeping power excessive, and magnet exciting coil burns because of overheat
The phenomenon ruined also occurs repeatedly；
2nd, power consumption：Another shortcoming of traditional DC electromagnetic valve is just to maintain the excessive and meaningless power consumption of power, reduces this
Plant power consumption, so that it may obtain the effect of " economize on electricity "；
3rd, it is out of control：After magnet exciting coil heating, its impedance increase, electric current diminishes, and electromagnetic force also reduces therewith, if now again
Secondary moving electromagnetic valve, valve element 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.
For the shortcoming of traditional DC electromagnetic valve, the present invention want Da to target be：
1st, " with electronics technological transformation conventional industries ", design a kind of electronic circuit try one's best device simple, used try one's best it is few
, price try one's best it is honest and clean, can make Traditional DC magnetic valve economize on electricity " power save unit "；
2nd, the Traditional DC magnetic 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
Output new " the pulsed economize on electricity DC electromagnetic valve " integrated with " power save unit ".
