SYSTEM FOR ADJUSTING TEMPERATURE OF GAS FLOW Russian patent published in 2006 - IPC G05D23/30 

FIELD: gas provision devices engineering.

SUBSTANCE: system contains heat exchanger, connected by input to source of high pressure compressed gas, and by output - to reducer. Output of reducer is connected to input of reverse flow of heat exchanger and to consumer through source washer. Output of reverse flow of heat exchanger is connected to through first adjusting valve to atmosphere. On consumer main, temperature sensor is mounted, connected to first input of temperature adjuster, second input of which is connected to set-point device. First output of temperature adjuster is connected to drive of first adjusting valve. Main of consumer between reducer and temperature indicator is divided on two lines, in which second and third adjusting valves are mounted with common drive, connected to second output of temperature adjuster. In one of lines, on which consumer main is divided, heater is mounted. Drive of first adjusting valve is provided with signaler of close position of valve, connected to temperature adjuster. Drive and second and third adjusting valves is provided by, connected to temperature adjuster, signaler of closed position of valve, mounted in one line with heater.

EFFECT: expanded range of temperatures of dispensed gas.
