Below in conjunction with drawings and Examples, the utility model will be further described.
In accompanying drawing, the mark that each label represents is as follows: permanent magnet, 17 second thrust-bearings, 18 power springs, 19 power springs, 20 supported springs, 21 valve seats, 22 sealing seats, 23 greasing joints, 24 O type circles, 25 positioning shafts, 26 bottoms on 1 valve body, 2 ball valves, 3 lower valve rods, 4 guide holders, 5 second flat keys, 6 times permanent magnets, 7 first thrust-bearings, 8 dividing plate gasket seals, 9 isolating plates, 10 valve gaps, 11 worm gears, 12 the 3rd flat keys, 13 power springs, 14 upper valve rods, 15 first flat keys, 16.
A kind of magnetic drives valve of the utility model, it mainly comprises valve body and the valve gap being connected with valve body, it is characterized in that: valve gap is connected with a worm gear operating device, forms a valve body chamber between valve gap and valve body, is provided with one group of permanent magnet in valve body chamber.One group of described permanent magnet is respectively the upper permanent magnet being located in valve gap, with the lower permanent magnet being located in valve body, between upper and lower permanent magnet, be provided with thrust-bearing and isolation mounting, described isolation mounting is isolating plate and the dividing plate gasket seal that is located at isolating plate one side, and isolation mounting is fixed between valve body and valve gap and by valve body and valve gap to be separated.In valve gap, be provided with matrix dish, upper and lower permanent magnet adopts rare earth permanent magnet ndfeb magnet, and upper and lower permanent magnet is plane permanent magnetic body, is distributed on matrix dish by NS interleaved mode.Described worm gear operating device is formed by connecting by worm gear with the upper valve rod of worm wheel, valve gap is provided with valve gap axis hole, in valve gap axis hole, be provided with upper valve rod, upper valve rod lower end is connected with upper plane permanent magnetic body by the first flat key, the upper end of upper valve rod is connected with worm gear operating device by the 3rd flat key, and upper valve rod is provided with three road power springs, and power spring and valve body keep in touch, endoceliac static can be derived, after earthed system, eliminate.
Upper and lower permanent magnet is made up of 4-12 piece magnetic patch respectively, and 4-12 piece magnetic patch is divided equally and is arranged in a disk, and it is fan-shaped that each magnetic patch is all, between magnetic patch and adjacent magnetic patch according to the interleaved mode arrangement of NS.In valve body, be provided with ball valve and valve seat, the spheroid of ball valve and valve seat composition sealing pair, be inlaid with polytetrafluoroethylsealed sealed circle on valve seat, be processed with the hard sealing surface mating with spheroid on valve seat, and valve seat is provided with seal gease passage.Spheroid lower end is provided with locating stud, and the bottom of valve body is provided with bottom, and valve body has valve body axis hole, and locating stud is arranged in valve body axis hole and by bottom and supports.On ball valve, be connected with lower valve rod, between described lower valve rod and lower permanent magnet, be connected by the second flat key.
In force, rotate the operation handwheel of worm gear 11, drive upper valve rod 14 to rotate, valve rod 14 passes to upper permanent magnet 16 by flat key 15 by worm gear moment of torsion.Under strong magnetic field action, upper permanent magnet 16 sees through isolating plate 9 and is coupled with lower permanent magnet 6, and the moment of torsion of upper permanent magnet 16 is delivered to lower plane formula permanent magnet 6.Lower plane formula permanent magnet 6 drives lower valve rod 3 to rotate together by flat key 5, and then the spheroid of actuate valve stem does switching motion.
In implementation process, because the moment of torsion transmission between upper valve rod 14 and lower valve rod 3 is contactless transmission (as Fig. 2), valve body 1 chamber medium is isolated plate 9 and intercepts completely, has stopped the possibility of dielectric leakage.And on traditional ball valve, seal as shown in (as Fig. 3), due to reasons such as the motion of valve rod and the wearing and tearing of filler, the gap of endoceliac medium through between valve rod and filler, leaks into the external world.Contrast knownly, the utility model, than traditional type axial seal structure, has higher Security.
