Embodiment
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
As shown in Figures 1 to 4, the utility model sealed electromagnetic valve comprises coil 1, static iron core 2, spring 5, conduit 6, dynamic iron core 7, spiral cover 10, jump ring 11, first back-up ring 12, second back-up ring 13, second Sealing 14, packing ring 15, valve body 16, piston 17, the first groove 111 is provided with in coil 1, static iron core 2, conduit 6 is all inserted in the first groove 111, dynamic iron core 7 is provided with the second groove 71 and the 3rd groove 72, spring 5 is positioned at the second groove 71, one end of conduit 6 is enclosed within static iron core 2, the other end of conduit 6 is enclosed within dynamic iron core 7, spiral cover 10 and piston 17 engage, spiral cover 10, jump ring 11, first back-up ring 12 is all positioned at valve body 16, first back-up ring 12 is positioned at below jump ring 11, second Sealing 14 is between the second back-up ring 13 and piston 17, packing ring 15 is between spiral cover 10 and valve body 16, the top of piston 17 is provided with the first fluting 172 and the second fluting 173, first back-up ring 12 and second is slotted 173 chimeric, jump ring 11 and first is slotted 172 chimeric.
3rd groove 72 is embedded between first Sealing 8, first Sealing 8 and the 3rd groove 72 and is provided with copper ring 9, and the centre of piston 17 is provided with a projection 171, and protruding 171 are positioned at below the first Sealing 8.Sealing is embedded in the 3rd groove, and such Sealing is not easy to come off, and can not leak.In addition, the first Sealing is clamped in the 3rd groove by copper ring further, and such first Sealing is more difficult to come off.Projection withstands the first Sealing, prevents the first Sealing from coming off further.
The side of coil 1 is provided with sleeve pipe 18, is so conveniently connected with other element, operates simple and easy.
