Abstract
(EN) Provided is a steam turbine with which miniaturization can be achieved using a configuration in which a pressure regulation valve is arranged in a region including an outer peripheral side with respect to a partition section. A steam turbine 1 is provided with: a partition plate 10 that partitions a high-pressure stage 101 and a low-pressure stage 102; and a pressure regulation valve 30 capable of regulating extracted steam pressure or mixed steam pressure. The pressure regulation valve 30 has a plurality of flow amount regulation valves V1 to V5 positioned on the outer peripheral side with respect to the partition plate 10 and supplied with steam from the high-pressure stage 101 side with respect to the partition plate 10, and has a plurality of flow path compartments 31 to 35 respectively corresponding to the plurality of flow amount regulation valves V1 to V5 and communicating with the low-pressure stage 102 side with respect to the partition plate 10. The plurality of flow path compartments 31 to 35 as a whole is arranged around the entire circumference of the partition plate 10 in a region including the outer peripheral side with respect to the partition plate 10. The partition plate 10 is provided with a bypass passageway 18 that provides communication between the high-pressure stage 101 side and the low-pressure stage 102 side without passing through the pressure regulation valve 30.
(FR) L'invention concerne une turbine à vapeur avec laquelle une miniaturisation peut être obtenue à l'aide d'une configuration dans laquelle une soupape de régulation de pression est disposée dans une région comprenant un côté périphérique externe par rapport à une section de séparation. La turbine à vapeur (1) est pourvue: d'une plaque de séparation (10) qui sépare un étage haute pression (101) et un étage basse pression (102); et d'une soupape de régulation de pression (30) apte à réguler la pression de vapeur extraite ou la pression de vapeur mélangée. La soupape de régulation de pression (30) a une pluralité de soupapes de régulation de quantité d'écoulement (V1 à V5) positionnées sur le côté périphérique externe par rapport à la plaque de séparation (10) et alimentées en vapeur depuis le côté étage haute pression (101) par rapport à la plaque de séparation (10), et a une pluralité de compartiments de trajet d'écoulement (31 à 35) correspondant respectivement à la pluralité de soupapes de régulation de quantité d'écoulement (V1 à V5) et communiquant avec le côté étage basse pression (102) par rapport à la plaque de partition (10). La pluralité de compartiments de trajet d'écoulement (31 à 35) dans son ensemble est disposé autour de toute la circonférence de la plaque de séparation (10) dans une région comprenant le côté périphérique externe par rapport à la plaque de séparation (10). La plaque de séparation (10) est pourvue d'un passage de dérivation (18) qui assure la communication entre le côté étage haute pression (101) et le côté étage basse pression (102) sans passer à travers la soupape de régulation de pression (30).
(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。
