Method of providing a multivalve turbine nozzle ring interface seal

摘要

The clearance necessary for the assembly of the nozzle ring of an axial flow steam turbine is localized through a temporary bolting. The localized clearance is compartmentalized by making a generally radially extending hole centered on the clearance at the circumferential location of the boundary between each pair of adjacent nozzle banks. Pins are driven into the holes and provide a seal between adjacent nozzle banks.
