Title
(JA) 蒸気タービン、仕切部材
Abstract
(JA)

仕切部よりも外周側を含む領域に調圧弁が配置される構成にあって、小型化を図ることのできる蒸気タービンを提供すること。蒸気タービン1は、高圧段101と、低圧段102とを仕切る仕切板10と、抽気の圧力または混気の圧力を調整可能な調圧弁30とを備える。調圧弁30は、仕切板10よりも外周側に位置し仕切板10よりも高圧段101側から蒸気が導かれる複数の流量調整弁V1〜V5と、複数の流量調整弁V1〜V5の各々に対応し、仕切板10よりも低圧段102側に通じる複数の流路区画31〜35とを有する。複数の流路区画31〜35は、全体として、仕切板10よりも外周側を含む領域において仕切板10の周方向の全体的に配置されている。仕切板10には、調圧弁30を経由しないで高圧段101側と低圧段102側とを連通させるバイパス路18が備えられている。
