とを特徴とする蒸気タービン。 In a steam turbine in which a turbine speed control stage is formed on both sides of an opening of a steam introduction passage formed in a turbine casing, a turbine speed control stage is provided on the outer periphery of the rotor between the two turbine speed control stages, and spaced apart on the outer periphery of the cylindrical base. A grid valve including a pair of side walls is rotatably mounted to face the steam introduction passage,
Openings for supplying steam from the steam introduction passage to both turbine governor stages are formed at intervals in the circumferential direction on both side walls of this grid valve, and the total area of the openings communicating with the turbine governor stages is formed. A steam turbine characterized in that a port ring for variable adjustment of the grid valve is adjacent to the grid valve.
