MIXER-TEMPERATURE CONTROLLER FOR WATER SUPPLY SYSTEMS Russian patent published in 2003 - IPC

FIELD: water supply systems. SUBSTANCE: invention is related to devices with adjusted parameters and can be utilized in the capacity of hot and cold water mixer and temperature controller in water supply systems. Mixer-temperature controller has body housing cold and hot water conduits and discharge conduit. With the help of thermal cylinder and control element based on two different-sized bellows it moves mixing tube shutting-off access of hot water from mixing chamber into mixing tube by actuator valve adjusting by that hot water flow in outlet conduit. Operation point is set by means of additional bellows. Proposed principle of temperature control can be employed in pipe-lines of various liquids and in gas pipe-lines. EFFECT: raised operational reliability of mixer-temperature controller, stability of specified temperature of water, increased accuracy adjustment of operation point. 2 cl, 3 dwg
