Abstract

PURPOSE: To device to supply steam smoothly from minute to the maximum discharge for improving the control of a turbine by constructing a steam stop valve with bypass valves to open these bypass valves successively.
CONSTITUTION: A steam stop valve with bypass valves is provided with an intermediate disk 240 to be vertically moved between a main valve 15 and a valve cap 19 equipped to the main valve 15 in one body, while the main valve 15 is provided with several bypass steam passages 20, which are constructed to be opened and closed by bypass valves 260W261 equipped to a fitting hole 250 on the intermediate disk 240. At this stage, when each bypass valve is at a position to close the above written passage 20, collars 260aW262a for bypass valves are respectively provided in different heights to the shoulder of the fitting hole 250. In this construction, bypass valves are respectively given different effective strokes S1WS3 to be successively operated for opening.
