Preferably, the coil is that two groups of unidirectional coils are an integrally-molded.
Preferably, the tail end of the spool is set as step-like structure.
Beneficial effects of the present invention:Compared with prior art, the present invention is small, reliability is high, can meet and uses work
Environmental requirement, as a result of novel armature structure, i.e., by cutting annular groove on armature, magnetism-isolating loop is fixed thereto, the knot
Structure not only improves the stressing conditions of magnetism-isolating loop, also substantially increases the reliability under engineering truck vibrations operating mode;It is online simultaneously
In terms of coil structures, the present invention by structure improvement and optimizing performance parameters, integrates 2 unidirectional coils existing in the prior art
For an individual Bidirectional push-and-pull structure coil through being an integrally-molded so that coil not only more steps up on contour structures
It gathers, but also the electromagnetic force of loop construction increases 30% or more.By the way that coil and coil case injection molding to be integrated, by conducting wire
Outlet method is revised as doubleleadout formula by traditional blade inserting outlet, further enhances the degree of protection of coil.Simultaneously originally
Invention uses Novel valve core structure, i.e., the length of spool is increased on the basis of traditional valve core, and be set to step
Shape structure can further decrease hydraulic power demand by this Novel valve core structure, improve the functional reliability of reversal valve.
