Method of replacing valve packing

摘要

A turbine fuel valve packing assembly including two sets of packing rings in which at least one packing ring is a V-shaped packing ring, a compression member, lantern ring, and packing gland with a sealing ring is disclosed which effectively seals turbine fuel valves against leaking. Further disclosed is a valve packing replacement method utilizing a bifurcated valve shaft allowing part of the shaft to be removed, thereby providing enough space for the valve packing assembly to be removed from the fuel valve and replaced without disassembling the entire fuel valve.
