FIELD: turbine manufacture. SUBSTANCE: control scheme has pulsed and forced oil supply lines running to automatic flap gate through common throttling port of turbine control gear. In case of fire in vicinity of turbine shutoff valve slide valves of turbine automatic safety device provide for oil drain to tank from all oil lines of automatic flap gate and closure of shutoff valve under action of actuating mechanism of turbine protection system. EFFECT: improved fire safety of control scheme. 2 dwg
