Self-Introduction automatic temperature control thermostatic valve, also known as self-operated valve, without outside energy and automatically adjust the temperature. Self-acting thermostatic valve for steam, hot water, hot oil for a variety of occasions medium heat. The valve is controlled medium temperature changes automatically adjust valve opening automatic valve functions in one based on a widely used heating, air conditioning, domestic hot water temperature is automatically adjusted, as well as automatic temperature control adjustment for special occasions, such as chemical , textile, pharmaceutical and other production engineering. Self-acting thermostatic valve with liquid thermal expansion and the principle of incompressible liquid automatic adjustment. Self-thermostatic expansion of the liquid within the temperature sensor is uniform, the control action is proportional adjustment. When accused of medium temperature changes, temperature sensors inside the liquid volume with the expansion or contraction. When accused of medium temperature higher than the set value, the temperature of liquid expands, pushing down the spool valve is closed, reducing the flow of heat medium; When Self-controlled thermostatic valve medium temperature is below the set value, the temperature of liquid contraction, to promote the return spring to open the valve body to increase the flow of the heat medium. Self-thermostatic structural principle: The product is mainly made up of body, valve seat, valve, valve cover, bulb, adjusting nut and other component parts. Self-low temperature control valve inlet valve automatically adjust heat transfer medium is carried out according to the size of the outlet temperature of the heat source and the heating medium heating system can be mixed directly into the use of self-loop system can also be used. Self-control valve and a temperature control valve comprises a thermostat (comprising a temperature sensor, a set point adjuster one, a working piston, and a capillary tube), relying on the state of the application to select a different temperature. Self-acting thermostatic valve without external energy and automatically adjust the temperature. Self-acting thermostatic valve for steam, hot water, hot oil for a variety of occasions medium heat. Self-acting thermostatic valve is widely used in heating, air conditioning, automatic temperature adjustment avid life, and temperature automatically adjust for special occasions, such as the chemical, textile, pharmaceutical and other production processes. Self-thermostatic heating and air conditioning, domestic hot water, petrochemical, electric power, electronics, textile, rubber, food and other industries. Self-use features of a thermostatic valve, small size, light weight, easy to install; 2, accurate and reliable long life; 3, free maintenance type work; 4, adjust the setting simple; 5, passive work (no power supply, gas supply work); 6, without costly commissioning costs; 7, the valve V-ring seal with high temperature seal assembly, to prevent the possibility of locking the stem too tight or leak. Self-Self-thermostatic temperature control valve works the use of liquid thermal expansion and the principle of incompressible liquid automatic adjustment. Expansion of the liquid within the temperature sensor is uniform, and its role is to control the ratio adjustment. When accused of medium temperature changes, temperature sensors inside the liquid volume with the expansion or contraction. When accused of medium temperature higher than the set value, the temperature of liquid expands, pushing down the spool valve is closed, reducing the flow of heat medium; accused of medium temperature is below the set value, the temperature of liquid contraction, return spring push Open the valve body to increase the flow of the heat medium.
