Introduction to the working principle and related knowledge of temperature control valve

Radiator thermostat controller - also known as: temperature control valve. In recent years, temperature control valves have been widely used in new construction houses in China. Temperature control valves are installed on heating radiators for residential and public buildings. The temperature control valve can set the room temperature according to the different requirements of the user. Its temperature sensing part constantly feels the room temperature and automatically adjusts the heat supply at any time according to the current heat demand, so as to prevent the room temperature from overheating and achieve the highest comfort of the user.

Temperature control in the user's room is achieved by the radiator thermostatic control valve. The radiator thermostatic control valve is composed of a thermostat controller, a flow regulating valve and a pair of connecting members, wherein the core component of the thermostat controller is a sensor unit, that is, a warm pack. The temperature pack can sense the change of the ambient temperature and produce a volume change, which drives the valve spool to generate displacement, and then adjusts the amount of water in the radiator to change the heat dissipation of the radiator. The temperature setting of the thermostatic valve can be artificially adjusted, and the thermostatic valve will automatically control and adjust the water volume of the radiator according to the setting requirements, so as to achieve the purpose of controlling the indoor temperature. The temperature control valve is usually installed in front of the radiator, and the room temperature required by the residents is realized by automatically adjusting the flow rate.

The temperature control valve has two-way temperature control valve and three-way temperature control valve. The three-way temperature control valve is mainly used for a single pipe system with a spanning pipe. The splitting coefficient can be varied from 0 to 100%, and the flow adjustment room is large, but the price is relatively expensive and the structure is complicated. Two-way temperature control valves are used for double pipe systems, and some are used for single pipe systems. The two-way temperature control valve for the double pipe system has a large resistance; the resistance for the single pipe system is small. The temperature sensing package of the temperature control valve is generally assembled with the valve body, and the temperature sensing package itself is the on-site indoor temperature sensor. If desired, a remote temperature sensor can be used; the remote temperature sensor is placed in a room that requires temperature control and the valve body is placed in a location on the heating system.

Thermostatic valves save energy and reduce your heating costs

The heating system is designed based on the statistically calculated maximum thermal load required at the lowest outdoor temperature. However, the design temperature of the thermostatic valve only appears in the cold season for a few days, which means that the heating system is running at full load only during these heating seasons. Generally speaking, the heat load required to ensure room temperature is much smaller than the design value, and the heat load is constantly changing. The daily heat load varies throughout the heating season. The thermostatic valve automatically maintains an accurate room temperature as intended, regardless of climatic conditions. A temperature-controlled valve is installed in each room to ensure that the “free” heat emitted by sunlight, lighting, machinery and the human body can be fully utilized to save energy.

Solve the problem of hydraulic balance in heating system

The temperature control valve is an indispensable component in the high-rise double-tube system, which can solve the water balance problem of the pipe network.
