Abstract

1420174 Fluid-pressure servomotor systems SOC DES ACIERS FINS DE L'EST 19 March 1973 [29 March 1972] 13060/73 Heading G3P A regulator R controlled by a ratio operator OR to maintain an air-flow 1 at a desired ratio to a gas flow 2 operates servomotor 5, 6 for control valves 3, 4 so that an increase in the regulator output through one range, say 200 to 800 millibars, opens one valve while an increase through a further range, say 850 to 1400 millibars, closes the other valve. The system may be used to control a gas furnace for heat-treatment and includes flowmeters 7, 8 connected to a recorder 9 and to the regulator R and operator OR. A selector MAG permits the servomotors to be placed under direct control. Electromagnetically actuated valves a...e and a'...e' provide selective control of separate zones in the furnace.
