Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Following example are used for illustrating this utility model, but are not limited to scope of the present utility model.
See Fig. 1, Fig. 2 and Fig. 3, execution valve described in this utility model one preferred embodiment, including housing 3, switch 5 and valve component, coil 10, switch 5 and valve body 1 it is provided with in housing 3, driven axle assembly and bead assembly is included in valve body 1, coil 10 is arranged on the rear side of bead assembly, coil 10 connects with housing 3 inwall, switch 5 is arranged on outside valve body 1, it is provided with protecgulum 4 and big magnet ring 23 on rear side of switch 5, housing 3 is arranged on protecgulum 4 rear, and housing 3 rear end is provided with external cap 7, and housing 3 and external cap 7 are provided directly with external connection 6.
Driven axle assembly includes driven axle 18, sealing shroud 16, back-up ring 20, directive wheel 14 and spring 19, spring 19 is arranged in the middle part of driven axle 18, sealing shroud 16 it is socketed with in the middle part of spring 19, U groove pad 17 it is provided with between sealing shroud 16 and driven axle 18 medial surface, sealing shroud 16 and valve body 1 contact position are provided with O 15, sealing shroud 16 rear is provided with back-up ring 20, back-up ring 20 connects with valve body 1, directive wheel 14 it is provided with after back-up ring 20, directive wheel 14 is connected with the internal diameter of valve body 1, and the rear of directive wheel 14 is provided with spacer ring 22 and minipad 13；
Bead assembly includes bead 11, inserts 12 and little magnetic piece 21, and little magnetic piece 21 is arranged in bead 11, is provided with inserts 12 between little magnetic piece 21 and bead 11, and inserts 12 is arranged on the rear of spacer ring 22.
