Abstract

PURPOSE: To relieve oil pressure drop of shut-off oil by resetting quick close sloenoid valve after specified time on arranging reset condition for resetting intercept valve quick close solenoid valve in order to reset intercept valve.
CONSTITUTION: With the deviation of intercept valve opening and command opening become more than 5%, a corresponding point among contact points LX, MX, NX is closed. A timer relay D, E, F may actuate simultaneously under the condition where turbine load is more than 20%, namely a contact point PX is closed. Those respective contact point DX, EX, FX may close simultaneously. Accordingly, all respective solenoid valves 36W41 are actuated. Thus, respective intercept valve opening is rapidly reduced. Even the contact points LXWNX actuated are restored by releasing quick closing signal like point F by opening reduction, a timer relay may not restore rapidly and open after elapsing restoring time.
