In order to make those skilled in the art person understand better the present invention program, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
With reference to Fig. 1-Fig. 3, the present invention is a kind of gate valve, comprise handle, valve body 5, valve gap, the isolating cylinder 2 that the valve rod 4 be connected with flashboard 6, described valve gap are top closure, described isolating cylinder 2 bottoms and described valve body 5 are rigidly connected (as be to be rigidly connected by screw bolt and nut in Fig. 1), and described handle is to be sleeved on the outer tubular handwheel 1 of described isolating cylinder 2; Be set with a tubular in described isolating cylinder 2 inner concentric and support yoke 3, described valve rod 4 is positioned at described support yoke 3 and described support yoke 3 is threaded; The outer interior magnetic shoe ring set 8 that is equipped with of described support yoke 3, on the inwall of described handwheel 1, corresponding position arranges an outer magnetic shoe ring set 9, described interior magnetic shoe ring set 8 and outer magnetic shoe ring set 9 include the magnetic shoe that even numbered blocks is evenly arranged, the magnetic shoe sheet number of interior magnetic shoe ring set 8 and outer magnetic shoe ring set 9 equates, and the magnetic shoe of the magnetic shoe of described interior magnetic shoe ring set 8 and outer magnetic shoe ring set 9 is all sequentially arranged according to N, S are extremely alternate, as shown in Figure 2, be the assembling schematic diagram of interior magnetic shoe ring set 8 and outer magnetic shoe ring set 9.
Preferably, described interior magnetic shoe ring set is contained on the peripheral outer surface of described support yoke, and described outer magnetic shoe ring set is arranged on the internal surface of sidewall of described tubular handwheel.Be arranged on outer placing, be convenient between magnetic pole attract to make mutual rotation.Also can be contained in other places.
As want opening/shutting valve, and only needing to rotate handwheel 1, outer magnetic shoe ring set 9 rotates, and interior magnetic shoe ring set 8 will automatically rotate under the effect of magnetic force thereupon, opens and closes and operates in totally enclosed isolating cylinder 2 and can complete, and therefore can realize the valve safety non-leakage.
Further, also comprise the axially movable axially locating system of the described valve rod 4 of a restriction.
Described axially locating system comprises upper branching holder, lower bearing support 11 and two groups of magnetic shoe disks, described upper branching holder and lower bearing support 11 upper and lower sleeves are loaded on outside described support yoke 3 and with described support yoke 3 and are rigidly connected, described two groups of magnetic shoe disks are set in outside described support yoke 3 up and down relatively, wherein one group of magnetic shoe disk on coil magnetic shoe disk 12 and be embedded in described upper branching holder bottom, below under the lower wall of one group of magnetic shoe disk magnetic shoe disk 15 be embedded in described lower bearing support 11 tops, one lower disk perpendicular to described support yoke 3 17 is arranged in the bottom of described support yoke 3, described lower disk 17 under the upper dish of top one group of magnetic shoe disk magnetic shoe disk 13 and below on the lower wall of one group of magnetic shoe disk between magnetic shoe disk 14, wherein, on to coil the magnetic shoe polarity of magnetic shoe disk 13 under magnetic shoe disk 12 and upper dish contrary, on lower wall under magnetic shoe disk 14 and lower wall the magnetic shoe polarity of magnetic shoe disk 15 contrary, as Fig. 3, for on coil the schematic diagram of upper magnetic shoe disk, its magnetic shoe is the S utmost point, and the magnetic shoe of following one group of magnetic shoe disk is the N utmost point, coil on described under magnetic shoe disk 12 and upper dish on magnetic shoe disk 13 and lower wall and have gap between magnetic shoe disk 15 under magnetic shoe disk 14 and lower wall.
Preferably, coil magnetic shoe disk 12 on described and include with magnetic shoe disk 13 under upper dish the magnetic shoe that even numbered blocks polarity is identical and be evenly arranged, on described lower wall, magnetic shoe disk 14 includes with magnetic shoe disk 15 under lower wall the magnetic shoe that even numbered blocks polarity is identical and be evenly arranged, and on coil under magnetic shoe disk 12, upper dish on magnetic shoe disk 13, lower wall the magnetic shoe sheet number of magnetic shoe disk 15 under magnetic shoe disk 14 and lower wall and equate with the magnetic shoe sheet number of described interior magnetic shoe ring set 8 and outer magnetic shoe ring set 9.
Described upper branching holder is bearing support 10, and described support yoke 3 is positioned at the ball bearing 16 on described bearing support 10, and described ball bearing 16 and bearing support 10 form the circumferential navigation system that the described valve rod 4 of restriction circumferentially rocks.Circumferential the rocking of supporting yoke 3 is subject to the constraint of ball bearing 16, and supporting yoke 3 will be in a stable working state, and the keying of valve operation will be brisk, flexibly.
Due to homopolar-repulsion, support yoke 3 in state of suspension, make and support yoke 3 and the friction of periphery nothing, realize the brisk operation of valve opening and closing.
In the outer rigid sleeve of described support yoke 3, annular inner magnetic core 7 is housed, described interior magnetic shoe ring set 8 is embedded in the peripheral outer surface of described inner magnetic core 7.Inner magnetic core 7 also without friction, opens and closes operation brisk with periphery.
