  • CLAPPER STYLE STOP VALVE SPHERICAL WASHER LAPPING TOOL
    Publication number: 20190270174
    Abstract: A device and method to aid in lapping a spherical washer to a steam turbine component are provided. The device includes a drive head, the drive head made up of a drive cap and a hollow cylindrical portion projecting from the drive cap. The drive cap abuts a surface of the spherical washer. The cylindrical portion fits within and is concentric to an inner diameter of the spherical washer. The device also includes an expanding gasket including an outer diameter having a contour configured to fit a contour of an inner diameter of the spherical washer and an inner diameter slides onto the cylindrical portion such that the gasket and cylindrical portion are concentric. The drive head attaches to a drive unit which imparts a torque to lap the spherical washer with respect to a steam turbine component. The expanding gasket expands and holds the spherical washer during the lapping.
