It is wound on skeleton 41；The core assembly 1 and the pedestal 2 are located at described every in magnetic inner cover 3 vertically；The core assembly 1
Including valve element 11 and the push rod 12 being connected on valve element 11；The pedestal 2 is with male cone (strobilus masculinus) near one end of the valve element 11
Tapering 21, and be provided with the resettlement section 24 for housing the valve element 11, the axle center of the pedestal 2 is additionally provided with guide through hole
2211, the push rod 12 is slidably disposed in the guide through hole 2211.
The hydraulic valve include valve body and can adjusting position vertically reversing bar, one end of the reversing bar and the top
Bar is against the other end is connected by stage clip with the inwall of the valve body.
After coil 42 is powered, valve element 11 and pedestal 2 are magnetized, and pole orientation is consistent, valve element 11 and pedestal 2 it is opposite one
The pole orientation at end is conversely, so as to mutually inhale with valve element 11 drives push rod 12 to be moved to the direction of pedestal 2.In the application, the base
Seat 2 is the tapering 21 with male cone (strobilus masculinus), the magnetic line of force warp of the surface formation of valve element 11 and pedestal 2 near one end of the valve element 11
Cross the male cone (strobilus masculinus) in tapering 21, from valve element 11 smooth it is excessive onto pedestal 2, magnetic resistance is small, magnetic force is uniform, it is therefore prevented that valve element 11 is acted
When Caton phenomenon, and then make magnetic valve obtain folding conversion it is more smooth.
Specifically, the pedestal 2 includes tapering 21, pars intermedia 22 and the extension base portion 23 of integrally connected shaping, it is described
Pars intermedia 22 is provided with radial support portion 221, and the middle part in the radial support portion 221 is provided with guide through hole 2211, the push rod 12
