  • Emergency shutoff valve exerciser for steam turbine and methods for installing and operating same
    Patent number: 6082393
    Abstract: An apparatus for exercising an emergency shutoff valve of a steam turbine and methods for installing and operating the same. A frame of the apparatus mounts on top of an emergency shutoff valve body and spans the axis of a valve stem of the emergency shutoff valve. A plunger is suspended from the frame and connects to the top of the valve stem of the emergency shutoff valve. The emergency shutoff valve, which is biased to spring closed, is held in place by the apparatus. With the valve thus secured, the tripping mechanism for the emergency shutoff valve can be disconnected from the valve stem and exercised, tested, or serviced. Additionally, the valve stem can be moved or exercised to assure its operability and to dislodge deposits or corrosion from the valve stem. Movement of the plunger is limited by retainer means that restrict movement of the plunger relative to the frame.
