The technological scheme of a kind of magnetic drives electric gate valve of the present invention; Adopt magnetic drives just can omit the bindiny mechanism of valve rod and the mechanism of carry-over moment; And the magnetic force that these two mechanisms only depend on a pair of magnetic pole to form replaces; Make between electric actuator and the valve and isolate fully through magnetic driving mechanism, valve is able to complete closed.A kind of magnetic drives electric gate valve of the present invention can make valve reach no external leakage fully, and sealing is reliable, can also make the compact structure of valve, reduces manufacture cost, therefore all will play positive role to environmental protection, personal safety.
Description of drawings
Fig. 1 is the structural representation of magnetic drives electric gate valve of the present invention.
Embodiment
In order to understand technological scheme of the present invention better, below through concrete embodiment and combine accompanying drawing to be elaborated:
See also Fig. 1, a kind of magnetic drives electric gate valve of the present invention comprises carriage 1, safety cover 2, electric actuator 3, magnetic driving mechanism 4, valve body 5, valve seat 6, globe disk 7, valve rod 8 and bottom 9.Wherein, magnetic driving mechanism 4 is installed between valve body 5 and the electric actuator 3; The bottom of valve body 5 is provided with runner; Valve seat 3 is located at respectively on the inlet/outlet of valve flowing channel; Globe disk 7 is located between the runner inlet/outlet of valve body; Globe disk 7 is connected the lower end of valve rod 8 through valve petal shelf 70; The external wall of upper portion face of valve rod 8 is provided with screw thread; Bottom 9 is installed in the lower end of valve body 5, is provided with packing ring 51 between this bottom 9 and the valve body.
Magnetic driving mechanism 4 comprises a support 41, an external rotor 42, an internal rotor 43, a radome 44, feedback rod 45 and crashproof ring 46, wherein,
Fixing setting-in one magnet circle 420 on the lower lumen wall of external rotor 42, this external rotor 42 is installed in rotation in the inner chamber of support 41, and the back-up ring 30 that passes through of this external rotor 42 is connected with electric actuator 3;
Fixing setting-in one Stem Mut 80 on the lower lumen wall of internal rotor 43, fixing suit one magnet circle 430 on the middle part outer wall of this internal rotor 43, this internal rotor 43 is installed in the inner chamber of external rotor 42, so that Stem Mut 80 screw-casings are contained in the top of valve rod 8;
Radome 44 is installed between external rotor 42 and the internal rotor 43, and the lower flange of this radome 44 is connected between the lower end surface of upper-end surface and support 41 of valve body 5.
Crashproof ring 46 is located between the lower lumen wall of bottom outer wall and support 41 of external rotor 42.
In addition, between the top internal chamber wall and radome 44 of internal rotor 43, be respectively equipped with a bearing 47,48 between the bottom outer wall of internal rotor 43 and the valve body 5.Be provided with the packing ring 52 that is used for leakproof between the upper-end surface of the lower end surface of radome 44 and valve body 5.
The working principle of a kind of magnetic drives electric gate valve of the present invention is:
Drive external rotor 42 rotations through electric actuator 3.Because external rotor 42 is equipped with a circle magnet 420, a circle magnet 430 also is housed on the internal rotor 43, inside and outside rotor 42, a radome 44 is arranged between 43, the rotation of external rotor 42 can produce magnetic force, thereby drives internal rotor 43 rotations.The rotating band ovable valve stem nut 80 of internal rotor 43 rotates, and moves up and down through the drive of the connecting thread on the Stem Mut 80 valve rod 8, thereby accomplishes the opening and closing action of gate valve.
A kind of magnetic drives electric gate valve of the present invention is owing to adopt magnetic force to drive the Kai Heguan of gate valve, thus in radome 44 by complete closed, can not cause that medium leaks outside.And in general electric valve, gate valve adopts packing seal and extraneous sealing, is difficult to guarantee to leak.External sealed leans on packing seal, is difficult to guarantee that zero lets out.
