Design principle: In the process of design, the stem deviates from center line of sealing face, this is the first eccentric structure; stem deviates from center line of pipeline, then it forms the second eccentric sturcture. The double-eccentric structure makes the seal more tight, reduces friction during opening and closing. Also, with smaller rotating angle, disc disaffiliates from seat ring, then it can prolong the valves' service life.
