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 spiral wound gasket for sealing flanged joints. The spiral wound gasket has improved sealability with a spiral sealing element that includes a metallic strip and a relatively soft filler material, wherein the axial width of the relatively soft filler material is greater than the axial width of the metallic strip. The spiral wound gasket also has improved sealability with a controlled gasket density and in which the metallic strip has a uniform and symmetrical “V” or “W” cross-sectional shape.
