Summary of the invention
The purpose of this utility model is, for the problems referred to above, a kind of two-position two-way solenoid valve of non-spring structure is provided, it is rational in infrastructure simple, design ingenious, be not provided with spring in product structure, avoided because spring failure or acting force of the spring produce less than the solenoid valve Problem of Failure that pressure medium causes stable and reliable product quality.
The technological scheme that the utility model adopts for achieving the above object is:
a kind of two-position two-way solenoid valve of non-spring structure, it comprises housing, valve seat, slide block, iron core, coil block, push rod and steel ball, this housing and iron core are fixed on valve seat, this coil block is arranged between this housing and iron core, this slide block can slide up and down to be arranged at the iron core upper end, this iron core is provided with a through hole that runs through its upper and lower surface, this through hole and the push-rod hole of being located on valve seat, filler opening is connected, also be provided with an oil outlet that is connected with push-rod hole on this valve seat, described steel ball can be limited in this filler opening by a snap ring up or down, this push rod can be arranged at through hole up or down, in push-rod hole, the two ends of this push rod respectively with slide block, steel ball contacts.
The lower end diameter of this push rod is less than its upper end diameter, and the lower end diameter of this push rod is less than the aperture of this push-rod hole.
It also comprises a copper sheathing, and this copper sheathing is fixed on the wall of this coil block center hole, and described slide block can slide up and down to be arranged at the upper end of copper sheathing, and described iron core is fixed in the lower end of copper sheathing.
Described coil block comprises coil, coil rack and two tenminal blocks, and this coil, tenminal block are individually fixed on this coil rack.
The diameter of described steel ball is greater than the aperture of this push-rod hole.
Described snap ring is provided with a center hole, and the aperture of this snap ring center hole is less than the diameter of this steel ball.
The beneficial effects of the utility model are: the utility model is rational in infrastructure simple, design ingenious, be not provided with spring in product structure, avoided because spring failure or acting force of the spring produce less than the solenoid valve Problem of Failure that pressure medium causes stable and reliable product quality.
Below in conjunction with accompanying drawing and embodiment, the utility model is further illustrated.

Structural representation when Fig. 2 is the utility model working state.
Embodiment
embodiment: see Fig. 1 and Fig. 2, the two-position two-way solenoid valve of a kind of non-spring structure of the utility model, it comprises housing 1, valve seat 2, slide block 3, iron core 4, coil block, push rod 6 and steel ball 7, this housing 1 is fixed on valve seat 2 with iron core 4, this coil block is arranged between this housing 1 and iron core 4, this slide block 3 can slide up and down to be arranged at iron core 4 upper ends, this iron core 4 is provided with a through hole that runs through its upper and lower surface, this through hole and the push-rod hole 21 of being located on valve seat 2, filler opening 22 is connected, also be provided with an oil outlet 23 that is connected with push-rod hole 21 on this valve seat 2, described steel ball 7 can be limited in this filler opening 22 up or down by a snap ring 8, this push rod 6 can be arranged at through hole up or down, in push-rod hole 21, the two ends of this push rod 6 respectively with slide block 3, steel ball 7 contacts.
The lower end diameter of this push rod 6 is less than its upper end diameter, and the lower end diameter of this push rod 6 is less than the aperture of this push-rod hole 21.
It also comprises a copper sheathing 9, and this copper sheathing 9 is fixed on the wall of this coil block center hole, and described slide block 3 can slide up and down to be arranged at the upper end of copper sheathing 9, and described iron core 4 is fixed in the lower end of copper sheathing 9.
Described coil block comprises coil 51, coil rack 52 and two tenminal blocks 53, and this coil 51, tenminal block 53 are individually fixed on this coil rack 52.
