Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a corner-type temperature control valve. Background Art

[0002] The temperature control valve is a typical application of the flow regulating valve in the field of temperature control. Its basic principle is to control the flow rate of the primary heat (cold) medium at the inlet of the heat exchanger, air conditioning unit or other heat-using and cold-using equipment to achieve the control of the outlet temperature of the equipment. When the load changes, the flow rate is adjusted by changing the opening degree of the valve to eliminate the influence caused by the load fluctuation and restore the temperature to the set value. Most of the existing temperature control valves control the opening and closing of the valve by motor drive. It is difficult to adjust the opening and closing of the temperature control valve when the power is off, which will affect the use effect of the temperature control valve and is not convenient for use.
