The role of the cylinder: separate turbine blading components of atmosphere, form steam energy conversion of closed space, and supporting other stationary parts of a steam turbine, such as baffle plate (Stationary blade ring), baffle plate sleeve (stationary blade carrier), steam seal, etc., To fix inlet, exhaust, and extraction steam pipes.
Steam inlet parts:
A. steam lead pipe: Send the steam through regulating steam valve into the nozzle chamber of steam turbine.
|Guide steam pipe||IP guide steam pipe|
|HP guide steam pipe||HP guide steam pipe flange|
B. nozzle chamber: Send the steam to steam turbine blading components directly; the first stage nozzle (set) of a steam turbine is fixed on the upper side.
|4# Nozzle group||1# Nozzle group|
C. Regulating steam valve: Used to change the amount of steam entering the turbine, regulate the speed or power of the turbine, and control the flow area of the first stage (high pressure regulating steam valve).
