FIELD: machine building.
SUBSTANCE: system of control of direction of flow in chamber regulating stages of steam turbine consists of control valves connected with their servo-motor, of nozzle boxes each with its segment of nozzles, of chamber of regulating stage, and of diaphragm of first stage of pressure. A rotating diaphragm containing a rotating ring is used for control of direction of flow in the chamber of stage regulation. The rotating ring is divided into autonomous segments each equipped with its own servo-motor. Working position of the servo-motor in its turn is related to a certain position of the control valve corresponding to it.
EFFECT: efficiency and reliability of partial compartment of steam turbine due to improved control of flow in chamber of regulating stage.
