Self operated temperature regulating valve
Product Description The self operated temperature regulating valve automatically adjusts the temperature without the need for external energy. It is suitable for various heat exchange occasions using steam, hot water, hot oil and other media. Widely used for temperature automatic regulation in heating, air conditioning, domestic hot water, and special occasions such as chemical, textile, pharmaceutical and other production engineering.
working principle The self operated temperature regulating valve utilizes the principle of liquid thermal expansion and incompressibility to achieve automatic regulation. The liquid expansion inside the temperature sensor is uniform, and its control function is proportional adjustment. When the temperature of the controlled medium changes, the volume of the temperature sensing liquid inside 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 downwards to close the valve and reduce the flow rate of the heat medium; When the temperature of the controlled medium is lower than the set value, the temperature sensing liquid contracts, and the reset spring pushes the valve core to open, increasing the flow rate of the heat medium.
Scope of Application Industries such as heating and air conditioning, domestic hot water, petrochemicals, electricity, electromechanical, textile, rubber, food, etc.
Product Features 1. Small size, light weight, easy installation 2. Accurate, reliable, and long lifespan 3. Maintenance free work 4. Simple mediation setting 5. Passive operation (normal operation without power or gas source) 6. No need for expensive debugging costs 7. The valve body seal adopts a V-shaped high-temperature sealing component to prevent the possibility of the valve stem being too tight or leaking.
