The self-operated temperature control valve is an instrument that can perform active temperature scheduling without requiring external power. It is suitable for various heat exchange conditions such as steam, hot water, and hot oil. It is widely used in heating, air conditioning, automatic temperature adjustment in daily hot water, and automatic temperature adjustment in special occasions, such as chemical, textile, pharmaceutical and other production processes. It uses the sensitivity of the spring to temperature, the built-in spring of the valve operates automatically, and uses the crystal transformation characteristics of the memory alloy material to achieve automatic scheduling. When the temperature of the controlled medium is higher than the set value, the spring force value increases, and the valve core is pushed down to close the valve, reducing the flow of the heating medium; when the temperature of the controlled medium is lower than the set value, the spring force value becomes smaller, The return spring pushes the valve core to open, increasing the flow of heat medium.
