Description
Technical field: the utility model relates to the two voltage energy-saving controllers of a kind of solenoid valve, especially a kind ofly can realize the two voltage energy-saving controllers of two voltage-controlled solenoid valves.
Background technique: the voltage signal of common solenoid valve input is single voltage signal, because before the suction behind the electromagnetic actuation is far longer than adhesive, caused the magnetic potential waste behind the electromagnetic actuation, has just caused waste of electric energy.
The model utility content: the technical problems to be solved in the utility model provides a kind of two voltage energy-saving controllers of solenoid valve that can realize two voltage-controlled saving electric energy.Technological scheme: the signal output part of single-chip microcomputer connects the control end of switching circuit, the signal input part of switching circuit connects power supply (VH), the signal output part of switching circuit connects an end of electromagnetic valve coil, and the signal output part of switching circuit also connects power supply (VL) through diode simultaneously.Beneficial effect: because the utility model can be realized two Control of Voltage, the little electric current of promptly big current start keeps, and can save electric energy more than 80%, because the temperature of electromagnetic valve coil is low, therefore can also prolong the working life of solenoid valve.
Description of drawings: accompanying drawing is circuit theory diagrams of the present utility model.
Embodiment: as shown in the figure, the signal output part of single-chip microcomputer U1 meets photo coupler G1A, the control end that the signal output part of photo coupler G1A connects switching circuit is the base stage of triode Q1, switching circuit is made of triode Q1, the switching circuit signal input part is that the emitter of triode Q1 meets power supply VH, the signal output part of switching circuit is the collector electrode connecting resistance R1 of triode Q1, and resistance R 1 connects the end of electromagnetic valve coil M, also meets power supply VL through diode D2 simultaneously.Another signal output part of single-chip microcomputer connects the base stage of triode Q2, the grounded-emitter connection of triode Q2, and the collector electrode of triode Q2 connects the other end of electromagnetic valve coil, is provided with diode D1 between the collector electrode of triode Q2 and the resistance R 1.The signal input part of the public termination photo coupler G2A of resistance R 1 and triode Q1, the signal output part of photo coupler G2A meets single-chip microcomputer U1.
When need were opened solenoid valve, single-chip microcomputer U1 gave an order and makes its P20 pin high level, triode Q2 saturation conduction; While P00 pin low level, triode Q1 saturation conduction, power supply VH are that high-voltage power supply is powered to electromagnetic valve coil M, and a bigger inrush current is provided.After solenoid valve was opened, through a few tens of milliseconds time-delay, single-chip microcomputer made its P00 pin high level, and triode Q1 ends.At this moment, power supply VL is that LVPS is powered to electromagnetic valve coil, and a less holding current is provided.When need were closed solenoid valve, single-chip microcomputer U1 made its P20 pin output low level, thereby triode Q2 is ended, and cut off electric current.When triode Q1, the whole conducting of Q2, if electromagnetic coil M normally, then the pressure drop that produces on resistance R 1 of inrush current makes light emitting diode, the phototriode conducting among the photo coupler G2A, making single-chip microcomputer P10 pin is low level, and whether can detect driving circuit for electromagnetic valve with this normal.
