SEGMENT OF CASING OF STEAM TURBINE, STEAM-TURBINE UNIT AND STEAM-TURBINE PLANT Russian patent published in 2016 - IPC F01D25/24 F01D25/28 

FIELD: turbines.

SUBSTANCE: proposed is steam turbine nozzle assembly remote control and measuring device. Steam turbine jacket segment (22) comprises horizontal connection surface (24), passage (46), opening, cover (48) and control element. Surface (24) has first opening (38), leading to cavity (36), made by mechanical processing in steam turbine shell segment (22). On cavity (36) opposite side there is also second opening (40), located substantially against first opening (38), wherein cavity (36) is made with possibility to hold supporting element (52) substantially in circumferential direction. Passage (46) has access from steam turbine jacket segment (22) radially outer surface (44) side, and it is connected to cavity (36) second opening (40). Opening has access from radially outer surface side, and it is flow-through connected to cavity second opening. Cover (48) is attached with possibility of disconnection and intended for closing said passage (46) on radially outer surface (44). Control element is arranged in said passage and passes, at least partially, into cavity. Fixing element is intended to retain control element in passage.

EFFECT: reduced time, cost and efforts for steam turbine nozzle assembly, jacket and rotor alignment.
