Document Type and Number:
Japanese Patent JP2001512544
Kind Code:
A
Abstract:
In order to obtain specially high live steam parameters (live steam temperature, live steam pressure) in a steam turbine, the admission (1) of a turbine housing has a flanged joint (4, 5) on the inside comprising multiple through-flow openings (7). Said flanged joint is used to fix a valve housing (2) for control valves (3) and has a sealing surface (15) encompassing each of the through-flow openings (7). In order to provide a particularly reliable sealing, high surface pressing is achieved in the sealing area by providing a shaped outer contour (16) of the sealing surface (15) in the area between adjaent through-flow openings (7) and by appropriately arranging different sized screws (6) along said shaped outer contour (16).
