Abstract
PURPOSE: To subject to improve the turbin simplely by means of using one part of the controller of a mechanical oil pressure system and one part of the controller of an electric oil pressure system in common.
CONSTITUTION: An operating mechanism 3 of a main steam adjusting valve 2 of a steam turbin 1 is actuated by both of the controller 20 of a mechanical oil pressure system and of the controller 21 of an electric oil pressure system. The operation mechanism 3 of the adjusting valve has a change-over valve which is installed in the front of the actuating cylinder of the main steam adjusting valve 2, and this change- over valve changes over the supply of an oil pressure from the pilot valve which is actuated by a link mechanism 8 of a mechanical oil pressure system and the supply of an oil pressure from an electric oil pressure converter 13.
