Temperature control valve is a typical application of flow control valve in the field of temperature control. Its basic principle is to control the inlet flow of heat exchanger, air conditioning unit other heat cooling equipment primary heat (cooling) medium to reach the outlet temperature of control equipment. When the load changes, adjust the flow by changing the opening degree of the valve to eliminate the impact caused by load fluctuation restore the temperature to the set value.

Structure working principle of temperature control valve

The temperature control in the user room is completed by the radiator thermostatic control valve. Radiator thermostatic control valve is composed of thermostatic controller, flow control valve a pair of connectors. The core component of thermostatic controller is sensor unit, namely temperature bag. The temperature package can sense the change of ambient temperature change the volume, drive the displacement of the valve core of the regulating valve, then adjust the water volume of the radiator to change the heat dissipation of the radiator. The set temperature of the thermostatic valve can be adjusted manually. The thermostatic valve will automatically control adjust the water volume of the radiator according to the set requirements, so as to achieve the purpose of controlling the indoor temperature. Temperature control valve is usually installed in front of the radiator, after automatic conditioning flow, to complete the residential demand room temperature. Temperature control valve has two-way temperature control valve three-way temperature control valve. The resistance of the two-way temperature control valve used for two pipe fragmentary is larger than that used for single pipe system. The temperature sensing package of the temperature control valve the valve body are generally assembled as a whole, the temperature sensing package itself is the indoor temperature sensor on site. If required, the short-range temperature sensor can be used; the short-range temperature sensor is placed in the room requiring temperature control, the temperature control valve body is placed in a certain part of the heating system. The three-way temperature control valve is mainly used in the single pipe system with crossover pipe. Its shunt coefficient can be changed in the range of 0-100%. There is a large room for flow adjustment, but the price is more expensive the structure is more complex. Some ZD of two-way temperature control valve is used for two pipe fragmentary, some for single pipe system.
