Abstract
PURPOSE: To prevent the fluctuation in the pressure of main steam, by rapidly opening a by-pass valve so that it is first kept at a such degree of opening as not to allow excess stream to flow and thereafter the degree of opening is heightened with the rise in the secondary pressure.
CONSTITUTION: A by-pass valve 7 is gradually opened in response to the closing action of a steam regulating valve 3, as shown by a curve (d'). The by-pass valve 7 is set at a degree LBCr of opening at the time tc of entire closing of the steam regulating valve 3 to enable a flow at a prescribed rate Go under the critical pressure. The degree LBCr of opening is maintained until the time tBD of the beginning of the rise in the secondary pressure. After the rise in the secondary pressure, the by-pass valve 7 is set at a rated degree LBn of opening at the time tBO when stationary pressure PB appears.
