摘要
A live steam passage of double-shell design for steam turbines is disclosed. According to the present invention, the steam passage is welded as a welded-in insert (1) onto the outer housing (9) of the turbine. The piston ring supoprt sleeve (2) with the piston rings (4) slides as a separate part in a sleeve (5), which the sleeve (2) is screwed onto the welded-in insert (1) with locking screws (3). A threaded ring (6) provided with a high collar holds the sleeve (5) in place in the inner housing (7) of the turbine. The live steam passage according to the present invention can be used in steam turbines, including throttle- controlled steam turbines with inner housings.
