What is the working principle of a thermostatic valve?
The core component of the thermostatic valve is the sensor, which is the temperature bulb. According to the location of the temperature bulb, there are two types of thermostatic controllers: built-in and external (remote). There are also two types of temperature settings, which can be set according to the window display and automatically controlled. The temperature bulb is filled with a temperature sensing medium, which can sense the ambient temperature and generate volume changes with the change of sensing temperature, driving the displacement of the regulating valve core, and then adjusting the amount of water passing through the radiator to change the heat dissipation capacity of the radiator. When the room temperature rises, the temperature sensing medium absorbs heat and expands, reducing the opening of the valve and reducing the amount of water flowing into the radiator to control the room temperature. When the room temperature decreases, the temperature sensing medium releases heat and contracts, and the valve core is pushed back by the spring, causing the valve opening to increase, increasing the amount of water flowing through the radiator, and restoring the set temperature of the room temperature thermostatic valve. The temperature can be manually adjusted, and the thermostatic valve will automatically control and adjust the hot water supply to the radiator according to the set requirements.
