The temperature control valve in the heat exchange unit, also known as the temperature regulating valve, mainly controls the inlet flow of the primary side heat (cold) medium adjust the outlet temperature of the heat exchanger or the heating (cooling) equipment, thus achieving automatic temperature control.
Working principle of the temperature control valve
1. The core component of the temperature control valve is a temperature sensor, which can sense the temperature of the medium the primary side and transmit the temperature signal to the actuator.
2. When the temperature deviates from the set value, the actuator will adjust the valve opening according to signal, thereby changing the flow of the medium on the primary side, so that the temperature returns to the set value.
Construction of a temperature control valve
Sensor
Senses the temperature and transmits the temperature to the actuator.
Actuator
Drives the valve movement based on the sensor signal.
Valve
Changes the flow rate to control the temperature.
Common Issues and Solutions
Actuator Not Responding Check the power supply, motor, and connector connections, especially the integrity of the ten- plug. If necessary, use the comparative interchange method to confirm the normal operation of the control module.
Incorrect Parameter Adjustment Irrational regulator parameter settings can lead system oscillations. Especially in single-loop control systems, setting too small a proportional band and too short an integral time can both cause oscillations. These parameters need to be adjusted through systeming methods to ensure system stability.
Motor Heating and Interference If the actuator motor is found to be overheating, first check for AC interference on the control's input terminals, and also ensure effective isolation between signal and power lines.
