STEAM VALVE, AND STEAM TURBINE APPARATUS COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2021/230086
Kind Code:
A1
Abstract:
This steam valve includes a valve casing, a valve body, a valve stem, an actuator, a heat buffer member, a link mechanism, and a link base. The heat buffer member includes: a heat buffer plate separated toward a leading end side from the valve casing in an axial direction in which the valve stem extends; and a support column that fixes the heat buffer plate to the valve casing so as to be incapable of relative movement. The actuator includes: an actuator casing; and an actuator rod that extends in the axial direction from in the actuator casing and that moves in the axial direction with respect to the actuator casing. The link base is fixed to the heat buffer member and extends from the heat buffer member in an axial perpendicular direction that is perpendicular to the axial direction. The actuator casing is fixed to the link base. The link mechanism is disposed more to a leading end side than an edge of a base end side of the link base.
