description	PROBLEM TO BE SOLVED: To provide a turbine emergency control valve capable of improving the reliability by further preventing pressure fluctuation of the pressure oil supplied to a main steam valve and the like during turbine operation.SOLUTION: A turbine emergency control valve according to an embodiment comprises upstream side common drain piping 25 connected to respective drain ports of a first master trip valve 1a and a second master trip valve 1b, and downstream side common drain piping 26 extending from the upstream side common drain piping 25 to the downstream side. The downstream side common drain piping 26 has an inverted-U seal piping part 27 which extends upward and then extends downward. Oil supply piping 28 for supplying oil to the upstream side of a top 27U in the inverted-U seal piping part 27 is connected to the inverted-U seal piping part 27. 【課題】タービン運転中における、主要蒸気弁等に供給される圧油の圧力変動を一層防止して、信頼性を向上させることができるタービン非常用制御装置を提供する。【解決手段】実施の形態によるタービン非常用制御装置は、第１マスタートリップ弁１ａ及び第２マスタートリップ弁１ｂの各ドレンポートに接続される上流側共通ドレン配管２５と、上流側共通ドレン配管２５から下流側に延びる下流側共通ドレン配管２６と、を備えている。下流側共通ドレン配管２６は、上方に延びた後に下方に延びる逆Ｕシール配管部２７を有している。逆Ｕシール配管部２７には、当該逆Ｕシール配管部２７における頂部２７Ｕよりも上流側に油を供給するための給油配管２８が接続されている。【選択図】図１
