Abstract

PURPOSE:To provide necessary and sufficient steam flow for starting by install- ing both a reheat stop valve and an intercept valve within the same casing and arranging them at the upper stream of steam. CONSTITUTION:A valve seat 26 formed on a valve casing 25 is constructed so as to be used as the valve seat common to those valves arranged in 2 steps, namely reheat steam stop valve(RSV) 6 on the upper step representing the upper stream side and intercept valve(ICV) 7 on the lower step representing the lower stream side. RSV6 is fitted slidably within a cylindrical inner face of a guide cylinder 28, and a steam flow route 51 of a flat plate portion 27 is opened through a globular small valve 12 and a valve stem 31 integrated with the valve 12. While, ICV7 includes a bypass valve 11 controlled through a valve stem 40 and placed above a large valve 37 having a steam flow route 37' for allowing reheat steam formed therein to flow downward.
