Elastic guide ring, movable iron core guide structure and electromagnetic valve

The utility model provides an elastic guide ring which is a wave-shaped ring, that is, a plurality of convex parts which are bent towards the radial outer side and a plurality of concave parts which are bent towards the radial inner side are formed on an annular body of the elastic guide ring at intervals. The utility model further provides a movable iron core guide structure which comprises the movable iron core, a guide sleeve and the elastic guide ring. The utility model further provides an electromagnetic valve which comprises a shell, an upper end cover, a lower end cover, a coil, a reset spring and the movable iron core guide structure. By adopting the technical scheme, the elastic guide ring is additionally arranged on the movable iron core, so that the guidance quality of clearance fit is solved, the frictional resistance between the guide sleeve and the movable iron core is reduced, the requirement on the surface roughness of the movable iron core is also reduced, the movable iron core can be effecti
