Abstract
PURPOSE: To perform fine adjustment of pressure in a chamber at any time even during operation of a turbine in a system used for a high pressure feed water system of nuclear power generation, by communicating a steam inlet chamber side to a balance chamber side in a valve box through a bypass pipe equipped with a flow control valve.
CONSTITUTION: The side of a steam inlet chamber 3 and the side of a balance chamber 7 in a valve box 1 are communicated by a bypass pipe 20, further a flow control valve 22 is provided in said pipe 20. Control pressure oil Q is fed to an oil hydraulic cylinder 13, and a pilot valve 11 is lifted to operate through a valve rod 12, then steam in the balance chamber 7 is released to an outlet chamber 5. If pressure in the chamber 7 is decreased, steam is fed from the steam inlet chamber 3 to the inside of the chamber 7 through drain piping 18 in the upstream side of the valve, bypass pipe 20, flow control valve 22 and through hole 21.
