Rotation, leading screw 13 rise with movable valve plug 17, and the sealing pair that static seal body 4 and dynamic sealing body 18 are formed departs from, and spool 17 reaches
Powered off during upper limit stroke, the medium channel on valve body 16 is connected with the dielectric channel hole 101 on hubbed flange 1, realizes valve
Open；When needing to close valve, motor 10 is inverted, leading screw 13 declines with movable valve plug 17, when spool 17 reaches lower limit stroke,
Static seal body 4 and dynamic sealing body 18 completely attach to, and under the action of pressure medium and magnetic spring force, form rigid seal pair,
Flow of media is cut off, realizes that valve is closed.
Sealing structure in the utility model is as follows：The power of motor 10 is by the rotation between outer rotor 8 and internal rotor 9
Turn magnetic field non contact transmission, across spacer 7 between outer rotor 8 and internal rotor 9, it is achieved thereby that with spacer 7 and valve body 16 it
Between instead of dynamic sealing between traditional transmission shaft and valve body by the static seal of sealing ring III 15；Hubbed flange 1 and valve body
16 are fixedly connected and form static seal connection by sealing ring I 2 between both phase veneers；Static seal body 4 and 1 phase of hubbed flange
The static seal structure formed between binding face by sealing ring II 3.The static seal structure and knot that above three sealing ring is formed
The rigid seal pair that the static seal body 4 between hubbed flange 1 and spool 17 and dynamic sealing body 18 are formed is closed, so as to be formed reliable
Interior outer seal configuration, effectively prevents valve leakage out of steam system, solves the inside and outside slip level of existing domestic valve and does not reach national standard
And imported valve service life it is short, of high cost the problem of.
The preferred embodiment of above-described embodiment, simply the utility model, is not used for limiting the utility model practical range,
