ZZWP self-operated temperature control regulating valve Operating principle :
ZZWP self-operated temperature control regulating valve use the principle of liquid heated expansion and incompressible liquid to realize automatic regulation. The control function is proportional regulation.When the temperature of the controlled medium changes, the volume of the temperature-sensitive liquid in the sensor expands or contracts.When the temperature of the controlled medium is higher than the set value, the temperature-sensitive liquid expands and pushes the spool down to close the valve, reducing the flow of the thermal medium.When the temperature of the controlled medium is lower than the set value, the temperature-sensitive liquid shrinks, and the return spring pushes the valve core to open, realizing the temperature balance control.On the contrary, the cooling valve opens above the temperature setting value and closes below the temperature setting value.Three - way valve an inlet, two outlets for the shunt, two inlet an outlet for the confluence.So as to realize automatic control of temperature.
