The radiator temperature control valve is an automatic control valve mounted on the radiator. The radiator thermostatic valve is a proportional control valve that can work without external energy. It regulates and controls the indoor temperature by changing the flow of heating hot water. It is an economical and energy-saving product. The control element is a warm pack, which is filled with a temperature sensitive substance. When the room temperature rises, the temperature pack expands to make the valve close, and the hot water supply of the radiator is reduced. When the room temperature drops, the process is reversed, so that the temperature can be controlled. purpose.
The radiator temperature control valve can also adjust the set temperature, and can automatically control and adjust the hot water supply of the radiator according to the set requirements. The key to the development of the temperature control valve is the temperature control part. The temperature sensing medium in the temperature control part of the temperature sensor can sense the outside temperature and react accordingly to control the opening of the valve core to control the flow through the temperature control valve. The temperature sensor is filled with liquid working fluid, gas working fluid, and paraffin wax. The three types of sensors have their own characteristics, the control precision is the best for liquid, the second is the second, the paraffin is the worst, but the paraffin is easy to use, the production process is low, unlike the gas and liquid working fluid is not tight and leakproof.
Sensors filled with liquid or gas working fluids have a working life of more than 20 years, and paraffin sensors have a working life of about 5 years. The radiator temperature control valve has two types of two-way valve and three-way valve with built-in preset device, which are applicable to the double pipe system and the single pipe system respectively. The preset temperature control valve is used in the double pipe system to overcome the vertical misalignment caused by the liquid gravity in the system. The three-way valve is beneficial to the water volume between the radiator branch pipe and the span pipe in the single pipe system due to the small resistance. distribution. Due to the large temperature difference between the supply and return water, the required radiator area is small, and the smaller size pipes and valves can be selected.
After the radiator temperature control valve is installed, the double pipe system becomes a variable flow system. The single pipe system requires a bypass pipe due to the installation of the radiator temperature control valve. Therefore, regardless of whether or not a radiator temperature control valve is installed, it is basically a constant flow system. If the heating system is a variable flow system, the frequency converter can be used to control the speed of the water pump to change the amount of circulating water. When the circulating water volume is reduced by 50%, the power consumed by the equipment can theoretically be reduced by 87.5%. Therefore, after using the radiator temperature control valve, the double pipe system can also obtain additional savings in power consumption. If the indoor is a single-tube system circulating water pump, it makes no sense to use a frequency converter. The double pipe system has not been promoted in the past, mainly because the vertical hydraulic imbalance caused by gravity in the double pipe system cannot be solved in the 3 or more floors or high-rise buildings. The radiator temperature control valve with built-in pre-set device solves this problem. The heating temperature required in the room can be preset by the temperature control knob in the valve head.
