ZZWP self-operated temperature regulating valve

The self-operated temperature regulating valve is composed of a temperature sensor and a control valve. It is an energy-saving product that uses the temperature changes of the controlled medium to automatically adjust without external energy. The product is suitable for use with various gases, steam, hot water, oil Automatic temperature control in various heat exchangers as media. It has the advantages of wide temperature setting range, easy adjustment, continuous temperature setting, over-temperature and over-load protection, and convenient temperature setting. It is widely used in urban heating systems and Electric power, petroleum, metallurgy, pharmaceutical boilers and other industrial sectors. Product features of self-operated temperature regulating valve
This valve does not require external energy such as electricity or compressed air. It is safe and reliable. The temperature-sensitive liquid expands uniformly and proportionally adjusts the control with high control precision. Stable operation, effective and energy saving The balanced valve body design enables the valve to operate under larger pressure differences. Linear or equal percentage flow characteristics. Temperature setting is simple and convenient. Small size, light weight and easy to install
Working principle of self-operated temperature regulating valve
Self-operated Type temperature control valve can be divided into temperature-controlled type for heating, temperature-controlled type for cooling, converging (diverting) and temperature-adjusting type according to the form of action. It is adjusted by using the principle that the temperature-sensitive liquid expands when heated, contracts when cooled and the liquid is incompressible. Insert the temperature sensor In a medium that needs to control the temperature, when the medium temperature rises, the expansion force of the warm liquid overcomes the spring resistance and pushes the valve core downward to move the valve to a closed state, thereby reducing the flow of the heat medium medium. On the contrary, when the medium temperature is lower than the set temperature, The temperature-sensing liquid shrinks and the return spring pushes the valve core to the open state to increase the flow of heat medium and make the temperature of the controlled medium tend to rise. The cycle is repeated so that the temperature value of the controlled medium is always maintained within the allowable range of the set temperature
