Technical field
The utility model relates to thermostatic control device, relates in particular to a kind of radiator valve circuit.
Background technology
At present, the temperature general control of birds, beasts and eggs hatching is between 36-39 ℃, and numerous small-sized birds, beasts and eggs hatching house is by the manual control temperature, its shortcoming is temperature control out of true, be not too high, be exactly low, affect the quality of little fowl after the product fowl rate of birds, beasts and eggs hatchings and the birds, beasts and eggs hatching, economic loss.
The utility model content
For solving the deficiencies in the prior art, the utility model provides a kind of temperature to control accurately, cost is low, the radiator valve circuit of high efficiency.
The technical problems to be solved in the utility model is achieved through the following technical solutions, the radiator valve circuit, comprise alternating current 220V power supply, electric heater EH, it is characterized in that: described radiator valve circuit also comprises power circuit and temperature detection control circuit, and described power circuit comprises decompression capacitor C1, drain resistor R1, commutation diode VD1, VD2, filter capacitor C2 and voltage stabilizing diode VS; Described temperature detection control circuit comprises thermal resistor RT, resistor R2, R3, potentiometer RP, light emitting diode VL, the accurate integrated regulator IC of three ends and bidirectional thyristor VT.
A termination power negative pole after described decompression capacitor C1, the drain resistor R1 parallel connection, the positive pole of another termination commutation diode VD1 and the negative pole of voltage stabilizing diode VD2, the negative pole of commutation diode VD1 connects positive source, filter capacitor C2 is with after voltage stabilizing diode VS is in parallel, one end of the positive pole of voltage stabilizing diode VS is connected with the positive pole of commutation diode VD2, and an end of the negative pole of voltage stabilizing diode VS is connected with positive source; The input end of the accurate integrated regulator IC of described three ends is connected with the positive pole of commutation diode VD2, the output terminal of the accurate integrated regulator IC of three ends is connected with the negative pole of light emitting diode VL, the positive pole of light emitting diode VL is connected with the gate pole G of bidirectional thyristor VT with resistor R2 series connection is rear, the central electrode T2 of described bidirectional thyristor VT with connect power cathode after electric heater EH connects, the central electrode T1 of bidirectional thyristor VT is connected with positive source, described potentiometer RP, resistor R3, after thermal resistor RT connects successively, the other end of potentiometer RP is connected with positive source, the other end of thermal resistor RT is connected with the input end of the accurate integrated regulator IC of three ends, the other end and the resistor R3 of the accurate integrated regulator IC of described three ends, the junction connects in the middle of the thermal resistor RT.
Described electric heater EH is Electrothermal fan.
The utility model alternating current 220V supply voltage is after C1 step-down, VD1, VD2 rectification, C2 filtering and VS voltage stabilizing, and the road is as defeated people's DC voltage of IC; Another road is after RT, R3 and RP dividing potential drop, for IC provides control voltage.
When dut temperature was lower than the design temperature of potentiometer RP, the resistance of thermal resistor RT was larger, and the control voltage of the accurate integrated regulator IC of three ends is higher than its cut-in voltage, the IC conducting, light emitting diode VL is lighted, and bidirectional thyristor VT is triggered and conducting, and electric heater EH energising begins to heat.Along with the continuous rising of temperature, the resistance of thermal resistor RT also begins to reduce, and the control voltage of IC also descends thereupon simultaneously.When dut temperature was higher than design temperature, the IC cut-off was extinguished VL, and VT turn-offs, and EH cuts off the power supply and stopped heating.Temperature begins again slow decreasing subsequently, and when dut temperature was lower than design temperature, IC is conducting again, and EH begins again energising and heats.So circulation is more than, and dut temperature is controlled at setting value.
The utility model adopts technique scheme will reach following technique effect: circuit structure is simple, and is reasonable in design, and applicable strong operability and temperature control are accurate, low cost of manufacture, and high efficiency, and stable and reliable for performance.
