Title:
蒸気タービンのための統合された抽気調整装置システム
Document Type and Number:
Japanese Patent JP4435425
Kind Code:
B2
Abstract:
An integrated bleed regulator system adapted to be fitted to a steam turbine, the system including a fixed part resembling a diaphragm and has a downstream part including distributor blades between an inner ring and an outer ring. A moving part is provided upstream of the fixed part and constitutes a regulator disk having distributor blades between an inner ring and an outer ring. The disk, according to its annular position, totally or partially obstructs a steam passage in the upstream to downstream direction or does not obstruct it at all and the surface of the regulator disk downstream of the inner and outer rings is at an upstream pressure (P1). A passage is also provided so that at least part of an upstream surface of the assembly formed by the inner and outer rings communicates with a space downstream of an upstream part of the distributor blades at a pressure (P2).
