Motorized self regulating temperature control valve introduction:
Motorized self regulating temperature control valve is composed of electric actuator, control valve body and temperature sensor.The Motorized self regulating temperature control valve only needs 220V power supply, which can be converted into the action signal of the electric actuator by using the energy change of the regulated medium itself, so as to realize the automatic regulation and control of the temperature of hot water, hot oil, steam and other medium.According to the customer's requirements, the Motorized self regulating temperature control valve can also adopt bit-type control, in the high limit to open or shut off, in the low limit to shut off or open;PID function is used to control temperature stabilization near the set value.The function of positive action and reaction setting satisfies the conversion of cold source regulation and heat source regulation.Due to the advantages of easy operation, simple structure, fast response time, wide range of temperature adjustment and reliable sealing performance, the electronic control valve has achieved good control effect in the automatic production and control of petroleum, chemical, food, residential, electric power, boiler and other industrial systems.
 
Motorized self regulating temperature control valve Working principle:
The main valve core of Motorized self regulating temperature control valve is in the half-open position and the sensor is in the natural state.After connecting to the power supply, the main valve is fully open.The medium flows into the main valve body by the direction of the arrow and heats the heat storage box by the valve core.When the temperature is higher than the set value, the temperature sensor generates corresponding linear signal input electric actuator produces an axial action, driving the stem and valve core to produce linear displacement, close the main valve core to stop heating.When the temperature of the electronic temperature control valve is lower than the set value, the sensor also generates corresponding linear signal input to the electric actuator, driving the control valve core to open, making the medium flow into the heat storage box according to the parabolic characteristics, and heating until the set value.Repeated circulation, so that the temperature of the controlled medium is always kept in the set range, so as to achieve the purpose of automatic control, this is the working principle of the electronic temperature control valve.
