Purpose and characteristics of self-operated temperature regulating valve
date:2026-02-26 12:50
The regulating valve consists of three parts: the main valve, intelligent actuator, and sensor. Depending on user needs, it comes in two structures: heating and cooling types.
Before operation, the main valve core of the self-operated temperature regulating valve is in a half-open position, and the sensor is in a natural state. When the power is turned on, the main valve core is fully opened. The medium flows into the main valve body from the direction indicated by the arrow and heats the thermal storage tank through the valve core. When the temperature rises to the corresponding set value, the sensor generates a corresponding linear signal to the integrated intelligent actuator, which then drives the valve rod and valve core to displace, closing the main valve core to stop heating. When the temperature is lower than the set value, the sensor generates a linear signal to the actuator, driving the valve core to gradually open, allowing the medium to flow into the thermal storage tank according to a parabolic characteristic, and heat it until it reaches the set value. In this way, the controlled medium is always controlled within the set temperature range, thus achieving temperature control.
