Abstract
PURPOSE: To prevent instantaneously steam inflow into a turbine when opening a steam stopping valve of the lower pressure side, by providing an opening action controller in a signal circuit between the entire circumferential injectors and the steam stopping valve of the lower pressure side.
CONSTITUTION: An opening action controller 8 consists of a cylinder 8, an oil cylinder pilot valve 10 which opens and closes a main steam stopping valve 4 in the lower pressure side and a lever 11 to connect to the valve 10. When the upper cylinder 12 of a cylinder 9 receives an order to open the steam valve at change-over points of the full circumferential injectors 6, a piston 14 in the upper cylinder 12 moves downward. The speed of the move is set on a dash pot mechanism. This action of the piston 14 actuates the lever 11 to open a port of the oil tank pilot valves, to permit the delivery of the operating oil into the oil tank. Then, the pilot valve of the oil tank 10 opens and can block the steam inflow into turbines.
