摘要： A live-loading assembly for exerting a sealing force on a compressible packing structure of a fluid handling device, such as a valve or pump, includes a pair of gland bolts each movably extending through opposite end lids of a tubular cartridge and through a Belleville spring stack disposed within the cartridge and bearing on a tubular piston rod having an end portion extending outwardly through one of the lids and having a spring force indicating scale disposed thereon. When packing force adjustment nuts are tightened onto the bolts, to increase the compression force exerted on the packing structures, one of the lids on each cartridge moves along the associated exposed piston rod scale to thereby provide a visual indication of the amount of spring force being created by each tightened nut.

摘要： A compressible anti-extrusion packing for sealing valve stems, shafts and rods having an interbraided, round braided or square braided outer layer disposed over a densified interbraided, round braided or square-braided core. In certain embodiments, the compressible packing includes a metal jacketed flexible graphite yarn interbraided as a core and an interbraided outer layer made of flexible graphite yarn with a carbon carrier. In one embodiment, the metal jacket is a knitted metal jacket. The core is densified by mechanical compression to control density and size.
