When Open valve, counterclockwise rotate dome formula outer magnetic ring handwheel (12) [annotate: several permanent magnets by the circular symmetric distribution apparatus constitute], [annotate: internal magnetic ring is the circular symmetric distribution apparatus and constitutes with the permanent magnets of outer magnetic ring handwheel (12) same number to utilize its rotation magnetic force square to rotate internal magnetic ring (10), connection set is in the Seal cage that spacer chamber (8) loam cake (13) is sealed], and rotate its underpart transmission shaft lever (9) [annotate: its hypomere is made joint tongue] and rotate multiple thread screw (6) that [annotate: its epimere is made tongue-and-groove (20), does the interlocking of sliding with the hypomere joint tongue of transmission shaft lever (9); (fast) multiple-threaded screw rod is made in its stage casing, is installed on fixing multiple-threaded nut (7); Hypomere is made diameter d
1Light face cylindrical bar], it is mobile that multiple thread screw (6) is rotated up, [annotate: diameter is d thereby make multiple thread screw (6) hypomere
1] d of light face cylinder rod end
1Nose cone, the center decompression hole (15) of small valve core piston (4) is opened, and the end face fluid of the small valve core piston (4) in the pressure reducing sleeve (5) is released, so the end face fluid pressure of small valve core piston (4) reduces, because the fluid pressure of its bottom surface, fluid pressure greater than its end face, so, act on the down pressure of small valve core piston (4) end face, upward pressure less than its bottom surface, cause pressure reduction, so small valve core piston (4) is risen, simultaneously the center decompression hole (16) of big valve core piston (2) is opened, and the end face fluid of big valve core piston (2) is released, so the end face fluid pressure of big valve core piston (2) reduces, because the fluid pressure of its bottom surface, fluid pressure greater than its end face, so, act on the down pressure of big valve core piston (2) end face, upward pressure less than its bottom surface causes pressure reduction, so big valve core piston (2) is risen, also the runner mouth (19) of shell-type valve body (1) is opened simultaneously, just flowed out from the runner mouth (19) of shell-type valve body (1) by the fluid in the channel flow inlet valve body.So multiple thread screw (6) is along with dome formula outer magnetic ring handwheel (12) Spin Control and adjusting, i.e. may command and controlling opening of valve and flow.
