Abstract
The utility model discloses a control circuit structure of big caliber electromagnetic valve, which has higher and more stable safety and low cost. The control circuit structure can apply the voltage multiplying rectifier principle in the closure of electromagnetic valves, keeps extremely small current in a voltage-doubler charging circuit through a current-limiting resistance, and can charge an energy storage capacitance through commonly utilizing the voltage multiplying voltage and bridge rectifier voltage. The technical scheme solves the problem of electromagnetic interference, and reduces near a half production cost compared with the prior art, because the capacity of the capacitance is limited, and the instant instantaneous discharge can not generate any affects to an electromagnetic coil.

Fig. 2 is the voltage-multiplying circuit figure that the utility model adopted.
Embodiment
As described in Figure 1, control circuit structure of the present utility model comprises that transformer unit, the solenoid valve that connects external power supply, the warning MCU that is connected in the external alert circuit drive relay unit.Two output terminals of transformer respectively are connected in series a current-limiting resistance R100 and a R200, described current-limiting resistance back is connected to the end that storage capacitor C13 is connected in solenoid valve after respectively being connected in series a charging capacitor C20 and C21, three commutation diode D11, D12 and D13 respectively are serially connected with and play the electromotive force conducting between the corresponding electric capacity and constitute voltage doubling rectifying circuit by effect; Have a bridge circuit to be connected in series connection one the 3rd current-limiting resistance R300 behind the output terminal of transformer and be connected to the other end of described storage capacitor, and this end is connected in the other end of solenoid valve by warning MCU driving relay unit by the 4th diode D14.
In this specific embodiment, described transformer unit is input as 220V power supply output 8-10AC electric current; The energy storage value of storage capacitor C13 is 470U/50V; Current-limiting resistance R100, R200 and R300 make the electric current in the multiplication of voltage charging road very little, approximately have only several milliamperes, do not influence the power supply of this circuit fully.If current limliting does not have tens milliamperes electric current, alarm circuit is produced certain influence.
Circuit theory of the present utility model is: the 8-10AC that the transformer transformation goes out exchanges, electromotive force is E2, when E2 is upper half (on just down negative), D12 ends, and the D11 conducting is through R100, after the R200 current limliting, charge to C20, voltage on the C20 is charged to peak value 1.414E2 near E2, and remains unchanged, at the negative half period of E2, D11 ends, D12 conducting, the voltage on the C20 addition of connecting with E2, electric current charges to C21 by D12, charging voltage is: 2 times of E2 of 2 times of radical signs, energy storage 470U/50V capacitor C 13 is charged to it by D13, repeatedly after the charging, approximately charging is after 30 seconds, the voltage E3 of C22 also is: 2 times of E2 of 2 times of radical signs, owing in the side circuit load is arranged, E3 voltage should be: 2.6E2.
The other end is powered to C13 by a current-limiting resistance R300 and diode, thereby is obtained E3=2.6E2+1.4E2=4E2 owing to obtain a VCC=E4=1.4E2 behind the bridge rectifier.
When alarm equipment alarm, high level of several seconds of MCU output drives cut-off, and with connecting the electric capacity two ends, electric capacity discharges to solenoid valve, thereby closes valve.
