The working principle of the automatic temperature control valve

Self operated temperature control valve using the principle of thermal expansion of liquids and liquid can not be compressed to achieve the automatic adjustment. Expansion of the liquid temperature sensor is uniform, the control effect of proportional control. Charged medium temperature sensor, the temperature sensing liquid in volume with the expansion or contraction. The controlled medium temperature is higher than the set value, temperature of liquid expansion, pushing the valve shut down valve, reduce the flow of heat medium; the temperature of the controlled medium is lower than the set value, temperature of liquid contraction, reset spring to push open the valve core to increase the flow of heating medium.
