Description
The steam distribution of the VDC is throttle. Steam supply is carried out through two blocks of valves: stop and regulating, located separately from the turbine DDC. The flowing part of the DDC is of reactive type and consists of 16 pressure stages. The working and guide blades have a T-shaped design of the tail joint and a one-piece milled band. Spring-loaded overband seals of the labyrinth type are used. The rotor is one-piece forged without an axial channel.
