The principle of temperature control valve-what is a temperature control valve

RADIATOR VALVES known as: temperature control valve. In recent years, temperature control valves have been widely used in new residential buildings in my country. The temperature control valves are installed on heating radiators in residential and public buildings. The temperature control valve can set the room temperature according to the different requirements of users. Its temperature sensing part constantly feels the room temperature and automatically adjusts the heat supply according to the current heat demand at any time to prevent the room temperature from overheating and achieve the highest comfort of the user.

The principle of temperature control valve—the working principle of temperature control valve

The temperature control in the user’s room is realized by the radiator thermostatic control valve. The radiator thermostatic control valve is composed of a thermostatic controller, a flow regulating valve and a pair of connecting parts. The core component of the thermostatic controller is the sensor unit, that is, the temperature bulb. The temperature bulb can sense the change of the surrounding environment temperature to produce volume changes, drive the adjustment valve spool to produce displacement, and then adjust the water volume of the radiator to change the heat dissipation capacity of the radiator. The set temperature of the thermostatic valve can be adjusted manually, and the thermostatic valve will automatically control and adjust the water volume of the radiator according to the set requirements, so as to achieve the purpose of controlling the indoor temperature. The temperature control valve is generally installed in front of the radiator to automatically adjust the flow rate to achieve the room temperature required by the residents.

The temperature control valve is divided into two-way temperature control valve and three-way temperature control valve. The three-way temperature control valve is mainly used in a single-pipe system with a spanning pipe. Its shunt coefficient can be varied within the range of 0-100%, and there is a lot of room for flow adjustment, but the price is more expensive and the structure is more complicated. Some two-way temperature control valves are used in two-pipe systems, and some are used in single-pipe systems. The resistance of the two-way temperature control valve used in the two-pipe system is relatively large; the resistance used in the single-pipe system is relatively small. The temperature sensing bulb of the temperature control valve and the valve body are generally assembled as a whole, and the temperature sensing bulb itself is the on-site indoor temperature sensor. If necessary, a remote temperature sensor can be used; the remote temperature sensor is placed in the room that requires temperature control, and the valve body is placed in a certain part of the heating system.
