COMPLEX COMBINED STEAM TURBINE DIAPHRAGM CONNECTOR Russian patent published in 2024 - IPC F01D25/24 

FIELD: turbine engineering.

SUBSTANCE: invention is related to the design of a connector for steam turbine diaphragms. The technical problem that the claimed invention is aimed at solving is the known disadvantages of straight, oblique, and combined connectors. The problem is solved by a complex combined connector of the steam turbine diaphragm, characterized by the presence of upper and lower halves of the diaphragm, which have a straight and combined connector. A distinctive feature is that there is a direct connector along the rim to the guide blade, cut along the periphery, and a combined connector is made along the entire body of the diaphragm.

EFFECT: increase of manufacturability and simplification of the design of the horizontal steam turbine diaphragm connector while maintaining the advantages of the previous art.
