Abstract

PURPOSE: To heighten the reliability of a turbine provided with a steam regulating valve controlled to be opend or closed depending on the exhaust pressure of the turbine, by switching a exhaust pressure load restrictor in light-load operation into such a state that the restrictor operates in response to lower exhaust pressure than in heavy-load operation.
CONSTITUTION: In the heavy-load operation of a turbine 1, an exhaust pressure load restrictor 5 is set in a position lower than that shown in the drawing. The restrictor 5 in the set position detects the pressure in a steam condenser 3. When the pressure in the steam condenser 3 exceeds a set level, the bellows 6 of the restrictor 5 expands to reduce the degree of opening of a steam regulating valve 2 through a rod, a lever 10 and a link 15. In the light-load operation of the turbine 1, a valve stem 29 is pushed down according to an operating instruction 19 and a connection 31 is swung closkwise centering a fulcrum 32 so that the restrictor 5 is set in a position for the light-load operation, through an arm 33. The restrictor 5 in the latter set position detects the pressure in the steam condenser 3 more sensitively.
