The technological scheme of a kind of magnetic drives electric gate valve of the present utility model, 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 by magnetic driving mechanism, valve is able to complete closed.A kind of magnetic drives electric gate valve of the present utility model 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 utility model.
Embodiment
In order to understand the technical solution of the utility model better, also be elaborated in conjunction with the accompanying drawings below by specific embodiment:
See also Fig. 1, a kind of magnetic drives electric gate valve of the present utility model 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 by 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.
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 the upper-end surface of valve body 5 and support 41.
Crashproof ring 46 is located between the lower lumen wall of the bottom outer wall of external rotor 42 and support 41.
