The invention relates to an apparatus and a method for orienting a guide vane support relative to a turbine casing. The apparatus has a guide device with a first region which is arranged in a seat of the guide vane support and a second region which is arranged in a recess of the casing. The second region has a guide channel with a first internal thread in which there is arranged a first adjusting element with a first external thread which can be screwed together with the first internal thread. The first adjusting element can be arranged in the guide channel such that, when the guide device presses against a supporting face of the recess, a force flow from the seat to the guide device runs through the first adjusting element. In the guide channel there is arranged a second adjusting element with a second external thread which can be screwed together with the first internal thread. The second adjusting element can be arranged in the guide channel such that a force flow from the upper part of the casing to the guide device runs through the second adjusting element. The first adjusting element is secured against relative rotation with the second adjusting the element by a securing device.

摘要:
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).
