Radiator thermostat (Radiator Thermostat, also known as temperature control valve, thermostat, etc.) installed in each radiator inlet pipe, the user according to the requirements of the room temperature, adjust and set the room temperature. According to its working principle, the thermostatic valve is proportional controller, that is, according to the room temperature and thermostatic valve setpoint deviation, in proportion, smoothly open or close the valve. The opening of the valve is maintained at the position corresponding to the demand load, and the water supply and the room temperature remain stable. Relative to a set value when the thermostatic valve from full open to fully closed position of the room temperature range is called the thermostatic valve proportional band, usually proportional band 0.5 ~ 2.0 ℃. According to the purpose of setting the thermostat valve, the user can adjust the room temperature by himself. Meanwhile, when there is "free heat" in the room, the thermostatic valve can regulate the water inflow and keep the room temperature constant, which not only improves indoor comfort but also saves energy. Radiator thermostatic valve to achieve the user can adjust the room temperature, heat distribution table with the heat meter, or a system for the household heat meter, you can figure out the actual consumption of heat per household, which is essential by the heat charge of the device . However, for a two-pipe system, the heating system is characterized by a variable volume due to the radiator thermostatic valve. If the pump operating conditions remain unchanged, when the system in some of the loop thermostatic valve off hours, will cause some loops on the thermostatic valve to withstand the increased pressure, worsened control performance; the other hand, the total system water demand Reduce, you can use (frequency) speed pump to save the power consumption of the pump. Thermostatic valve works Thermostatic valve is the core component of the sensor, that temperature package. According to the location of temperature package, the temperature controller has temperature package built-in and temperature package external (remote) in two forms, there are two temperature settings, you can follow the window display to set the required control temperature, and automatically control. Warm bag filled with a sense of temperature medium, capable of sensing the ambient temperature, with the changes in the temperature of the induction volume changes, drive the valve spool displacement, and then adjust the radiator through the water to change the radiator heat dissipation. When the room temperature increases, the temperature sensing medium endothermic expansion, off the valve opening, reducing the amount of water flowing into the radiator, reducing heat dissipation to control the room temperature. When the room temperature decreases, the heat medium shrinking heat, the valve is pushed back by the spring so that the valve opening increases, increasing the amount of water flowing through the radiator to restore the room temperature thermostat valve set temperature can be artificially adjusted, thermostatic valve will be set Requires automatic control and regulation of radiator hot water supply. Radiator thermostatic valve installation position Radiator thermostatic valve installed in each radiator inlet pipe or sub-household heating system inlet on the inlet. The installation of the radiator thermostatic valve is very important: The built-in sensor does not advocate vertical installation because the thermal effects of the valve body and the surface piping may cause the thermostatic controller to malfunction and the thermostatic valve sensor should sense the temperature of the circulating air in the room , Shall not be covered by curtain boxes, heating hoods and so on.
