Background
The temperature control valve is a flow control valve and controls the outlet temperature of the equipment by controlling the flow of heat exchangers, air conditioning units or other heat and cold equipment and primary heat (cold) media inlets. When the load changes, the flow is adjusted by changing the opening degree of the valve to eliminate the influence caused by the fluctuation of the load, so that the temperature is recovered to the set value. The three-way temperature control valve generally comprises two water inlets and a water outlet, wherein cold water and hot water are respectively fed into the two water inlets, and the on-off of the two water inlets and the water outlet is controlled through a valve core to adjust the water temperature at the water outlet. The existing three-way temperature control valve has a complex structure, the sealing performance of the valve core is poor, and after the three-way temperature control valve is used for a long time, the temperature control sensitivity is reduced, so that the use is influenced.
