When the load changes, the flow rate is adjusted by changing the valve opening degree in order to eliminate the effects of those load fluctuations and restore the temperature to the set value. The control parameters can be adjusted flexibly to achieve system optimization. By analyzing the flow characteristics of the temperature control valve and those of the radiator, and by introducing the concept of valve weighting, the thermal properties of the radiator are explained. The installation scheme for the temperature control valve is also presented, and finally, its energy-saving effects are discussed. The thermal bulb can change its volume in response to changes in the surrounding temperature, which in turn causes the valve spool to move, thereby adjusting the amount of water flowing through the radiator and thus changing its cooling capacity. The set temperature of the thermostatic valve can be adjusted manually; it automatically controls and regulates the water flow to the radiator according to the set parameters, thereby achieving the goal of controlling the indoor temperature. The high resistance of the temperature control valve is determined by the regulating characteristics of the radiator; this characteristic of the temperature control valve must be taken into account during design to avoid insufficient operating pressure. The rotation of the handle is converted into linear displacement of the valve spool through a screw. To accommodate the linear movement characteristic of the actuator in temperature control sensors, the movement of the valve core in automatic temperature control valves is typically designed as a linear displacement that can automatically return to its original position; therefore, these two types of valve bodies generally cannot be interchanged. However, there are also specially designed valve bodies that are interchangeable and can be used universally; that is, by using a valve body with a temperature control valve and adding an appropriate manual screw lifting mechanism, it is possible to achieve interchangeability between manual and automatic operation. In particular, vertical installation is not recommended for built-in sensors, as the thermal effects of the valve body and the surrounding pipes may cause the thermostatic controller to malfunction; it is necessary to ensure that the sensor of the thermostatic valve can detect the temperature of the air circulating in the room.
