Abstract

PURPOSE: To add an equivalent force to the steam force without incorporating the turbine by-pass valve into the turbine plant by setting a simulative load oil pressure cylinder against the oil pressure cylinder for opening and closing operation of turbine by-pass valve.
CONSTITUTION: A simulative load oil pressure cylinder 17 is set against the oil pressure cylinder 4A for opening and closing operation of the turbine by-pass valve 2. The oil pressure cylinder 22 for pressure accumulation is set against the oil pressure cylinder 4B acting synchronously with the oil pressure cylinder 4A. An equivalent force to the steam force acting on the valve 2 is added simulatively by setting a servo valve 25 acting in accordance with the load detector 28 and the displacement detector 12. Thus the load performance on the valve itself can be secured without incorporating the turbine by-pass valve into the atomic energy plant.
