Description
Technical field
The present invention relates to Low Voltage Electrical Apparatus, more particularly to a kind of " electricity-saving type alternating current with the function of saving electric energy
Magnet valve ".
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.
Alternating current electromagnetic valve is the type in magnetic valve, is low using widely in household electrical appliance and industrial control equipment
Piezoelectricity device.It is characterized in incoming transport voltage, the electromagnetic force with alternating current generation driving valve open/close in magnet exciting coil.
Alternating current electromagnetic valve is mainly made up of magnet exciting coil, valve element, back-moving spring.Fig. 1 a, Fig. 1 b control for alternating current electromagnetic valve
The schematic diagram of fluid (gas or liquid) switching；Fig. 2 a, Fig. 2 b are the AC hydraulic solenoid valve control " hydraulic oil " in hydraulic test
The schematic diagram of flow direction.
With reference to Fig. 1 a：When logical AC220V, AC110V or AC380V voltage (the following common name of A1, A2 termination of magnet exciting coil
AC220V, AC110V or AC380V be AC voltages) when, its produce electromagnetic force promote valve element overcome back-moving spring resistance and to
Lower movement, the piston being connected with valve element is also moved down therewith, and described alternating current electromagnetic valve is opened, and its " entrance " connects with " outlet "
It is logical.
With reference to Fig. 1 b：When in magnet exciting coil AC voltages shut-off when, valve element loss of excitation power, by back-moving spring effect and on
Move, piston is also moved up therewith, described alternating current 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 AC voltages, 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 AC voltages in the magnet exciting coil of hydraulic buttery valve are 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 alternating current electromagnetic valve can be divided into " promotion ", " holding " RESET three phases：
1st, promote：A1, A2 end of magnet exciting coil and AC Voltage On states, electromagnetic force promote valve core movement；
2nd, keep：Valve element reaches the position of setting, and magnet exciting coil continues to continue by electromagnetism masterpiece with AC Voltage On states, valve element
With and be maintained on the position of setting；
3rd, reset：Magnet exciting coil disconnects AC voltages, valve element dead electricity magneticaction and resetted.
Aobvious you are clear to, in the stage of promotion, and valve element, which must pull against stiction and the elastic force of back-moving spring, needs larger electromagnetism

Such as AC220V), therefore, heating is serious, and the phenomenon that magnet exciting coil burns by overheat also occurs repeatedly；
2nd, power consumption：The energy of traditional alternating current electromagnetic valve heating is exactly to input electric energy in magnet exciting coil, such a harmful hair
Another shortcoming that the torrid zone is come is exactly meaningless power consumption.Reduce this 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 can not also be pushed away therewith reducing
Movable valve plug is to setting position, household electrical appliance or industrial control equipment meeting therefore and system is out of control.
For the shortcoming of traditional alternating current electromagnetic valve, the target of the invention to be reached is：
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 conventional AC magnetic valve economize on electricity " power save unit "；
2nd, the conventional AC magnetic valve that " power save unit " can be used for transformation to use online is somebody's turn to do, these alternating current electromagnetic valves is upgraded
As with electricity saving function alternating current electromagnetic valve；
3rd, being somebody's turn to do " power save unit " can also be integrated into the alternating current electromagnetic valve that will be produced, and give birth to the manufacturer of alternating current electromagnetic valve
New integrated with " power save unit " of output has electricity saving function " electricity-saving type alternating current electromagnetic valve ".
