Type self-operated temperature control valve (National Patent No.:.) is also called a self-operated temperature control valve. It can automatically adjust the temperature without external energy. It is suitable for steam, hot water, hot oil, etc. In various heat exchange situations of media, it is widely used in automatic temperature adjustment in heating, air conditioning, domestic hot water, and automatic temperature adjustment in special occasions, such as chemical, textile, pharmaceutical and other production projects.
The self-operated temperature regulating valve uses the principles of thermal expansion of liquid and incompressibility of liquid to achieve automatic adjustment. The liquid expansion in the temperature sensor is uniform, and its control function is proportional adjustment. When the temperature of the controlled medium changes, the temperature in the sensor changes. The volume of the temperature-sensing liquid 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 and reduce the flow of the heat medium. Self-operated temperature control valve The temperature of the controlled medium is low At the set value, the temperature-sensing liquid contracts, and the return spring pushes the valve core to open, increasing the flow of heat medium.
Features of the self-operated temperature control valve
The valve body seal adopts a ring high-temperature sealing component to prevent the possibility of the valve stem being over-tightened or leaking
Self-operated temperature control The valve is small in size, light in weight, easy to install
, passive operation (no power supply, normal operation of air source)
, no expensive debugging costs
, easy adjustment and setting
, Maintenance-free work
, accurate, reliable and long life.
