Working principle The imported self-operated temperature regulating valve uses the principle of thermal expansion of liquid and the incompressibility of liquid to achieve automatic adjustment. The liquid expansion in the temperature sensor is uniform, and its control function is proportional regulation. When the temperature of the controlled medium changes, the volume of the temperature-sensing liquid in the sensor expands or contracts. When the temperature of the controlled medium is higher than the set value, the temperature-sensing liquid expands, pushing the valve core downward to close the valve, reducing the flow of the heat medium. When the temperature of the controlled medium is lower than the set value, the temperature-sensing liquid contracts, and the return spring pushes the valve The core is opened to increase the flow of heat medium. It does not require any external energy, and uses the energy of the medium to be adjusted to realize automatic adjustment of the medium temperature.
Application of self-operated temperature control valve, also known as temperature control valve self-operated temperature control valve temperature control valve temperature control valve. It consists of control valve and thermostat. It is divided into heating type and cooling type according to usage. Suitable for temperature control of non-corrosive liquid gases and steam in various cooling systems. When the temperature of the controlled medium rises, the control valve closes the heating type. When the temperature of the controlled medium rises, the control valve opens the cooling type. It is suitable for various heat exchange conditions using steam, hot water, hot oil, etc. as the medium.
