Abstract:
An integrated bleed regulator system adapted to be fitted to a steam turbine, the system including:a fixed part having an outer ring and an inner ring; first distributor blades positioned between said inner ring and said outer ring; a moving part disposed upstream of said fixed part, said moving part comprising a rotatable regulator disk having second distributor blades, said second distributor blades having an upstream part, said regulator disk also including an inner ring and an outer ring, said inner ring and said outer ring respectively having upstream and downstream surfaces, where said regulator disk, according to its angular position, totally or partially obstructs a steam passage in the upstream to downstream direction or does not obstruct it at all, and the downstream surfaces of said inner and outer rings are at an upstream pressure (P1); and communication means which is provided so that at least one of the upstream surfaces of said inner and outer rings communicates through a portion of said regulator disk with a space downstream of said upstream part of said second distributor blades, at a downstream pressure of (P2).
