ABSTRACT:
A linkage device for a steam turbine stop valve includes a support member having a pair of transverse sections separated by a substantially vertical portion; a reciprocal stop valve stem fixed to one of the transverse sections, the stop valve stem extending substantially parallel to but laterally offset from the vertical portion; an actuator rod arranged in substantial axial alignment with the stop valve stem along a force line, one end of the actuator rod extending through a hole in the other of the transverse sections; and a multi link assembly extending between the stop valve stem and the actuator rod, including a first link pivotally secured at a first end to the one transverse section, and a second link pivotally secured at a first end to the actuator rod. Second ends of the first and second links are pivotally secured to each other by a pivot pin. A trip cylinder is utilized to move the pivot pin through the force line, causing the multi link assembly to collapse, thus permitting closure of the valve.
