摘要： A stem shoulder seal with double rings is composed of a sealing ring, a clamping ring and a spherical or conical stem shoulder, and the sealing ring is of a self-energized seal designed to its ultimate allowable strength and automatically free of any load beyond its ultimate strength. An assembly of independent dual stem seals, consisting of a stem shoulder seal with double rings, a stem cylinder seal with triangular sections and an isolating mating, can ensure that a stem has three seals which get well seated automatically at the same time to bear an identical ultimate medium pressure independently or without any mutual interference in service when assembled to the extent that the stem operating torque is just definitely increased, thereby ensuring that a stem sealing has a triple safety.

摘要： A sealing microsawtooth ring joint, made between a toothed seating surface and a full plain seated surface by a microsawtooth ring with its tooth crest on the seating surface being a cutting edge whose corner or whose crest angle is about 90°˜120°, with its tooth height Zt being about 10˜20 times the roughness Ra of the seated surface, and with the ratio of its tooth pitch Xs to its tooth height Zt being 20˜500 to ensure that the tight joint has a microcosmic line contact followed by a surface contact or to ensure that the tight joint has both such a line contact as to be able to provide a necessary seating stress locally and such a surface contact as to be able to protect the line contact from being excessively pressed to get blunt or disappeared, can be used either as a pressure-tight joint or as a self-energizing tight joint of any too surfaces such as flats to flats, cones to cones or spheres, spheres to spheres or cones etc., thus simplifying and unifying the designing, calculating, manufacturing, selecting, installing and maintaining of fussy gaskets for a tight joint of flat surfaces, avoiding the lapping of formed jointing surfaces without using soft gaskets, increasing the reliability of tight joints sod the utilizing coefficient of natural resources. The sealing microsawtooth ring joint can still have an extra sealing reliability and safety sensation by selectively adding one of four basic gland seals.
