Description
Technical field
The utility model relates to Electromagnetic Control field, particularly relates to a kind of solenoid valve.
Background technique
Solenoid valve is the industry equipment by Electromagnetic Control, is used to the automation foundation element controlling fluid, belongs to final controlling element, is not limited to hydraulic pressure, pneumatic.Be used in industrial control system adjust medium direction, flow, speed and other parameter.Solenoid valve can coordinate different circuit to realize the control of expection, and the precision controlled and flexibility can both ensure.At present, in use, sealing effect is poor for solenoid valve, has Seepage, and working life is short, and spring is fragile.
Model utility content
To the present situation of above-mentioned prior art, technical problem to be solved in the utility model is the solenoid valve providing a kind of long service life, good sealing effect.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of solenoid valve, comprise valve body and coil, sleeve pipe is provided with between described valve body and coil, this sleeve upper end extends to coil inside, lower end is sunk in valve body, dynamic iron core is provided with in described sleeve pipe, static iron core is provided with above this dynamic iron core, big spring and little spring is provided with in described dynamic iron core, this big spring and little spring and described static iron core offset, described its lower end is provided with row pressure breach, rubber tip is provided with below described dynamic iron core, this rubber tip and described valve body offset, described static iron core lower end is provided with divided magnetic ring.
Further, described valve body side is provided with import, and opposite side is provided with outlet, and this import passes to rubber tip place.
Further, be provided with an O shape and enclose between described sleeve pipe and described valve body, an O shape circle is placed in valve body upper-end surface, improves sealing.
Further, be provided with the 2nd O shape and enclose between described sleeve pipe and described coil, the 2nd O shape circle is placed in coil lower end surface, improves sealing.
Compared with prior art, the utility model has the advantage of: the utility model, by arranging big spring and little spring, improves the working life of spring; By arranging row pressure breach, for reducing the fashionable pressure to dynamic iron core of liquid stream; By arranging divided magnetic ring, for reducing noise and vibration; By arranging rubber tip, for improving sealing and working life, this practical design is reasonable, can large-scale promotion.
Accompanying drawing explanation
Fig. 1 is a kind of electromagnetic valve structure schematic diagram of the utility model.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, a kind of solenoid valve, comprise valve body 1 and coil 6, sleeve pipe 4 is provided with between described valve body 1 and coil 6, it is inner that this sleeve pipe 4 upper end extends to coil 6, lower end is sunk in valve body 1, dynamic iron core 7 is provided with in described sleeve pipe 4, static iron core 11 is provided with above this dynamic iron core 7, big spring 9 and little spring 8 is provided with in described dynamic iron core 7, this big spring 9 and little spring 8 offset with described static iron core 11, described sleeve pipe 4 lower end is provided with row pressure breach 14, rubber tip 2 is provided with below described dynamic iron core 7, this rubber tip 2 offsets with described valve body 1, described static iron core 11 lower end is provided with divided magnetic ring 10, described valve body 1 side is provided with import 12, opposite side is provided with outlet 13, this import 12 passes to rubber tip 2 place, be provided with an O shape between described sleeve pipe 4 and described valve body 1 and enclose 3, one O shape circle 3 is placed in valve body 1 upper-end surface, improve sealing, be provided with the 2nd O shape between described sleeve pipe 4 and described coil 6 and enclose 5, 2nd O shape circle 5 is placed in coil 6 lower end surface, improve sealing.
Working principle brief description:
Solenoid valve is started working, and coil 6 is energized, and dynamic iron core 7 moves upward, and rubber tip 2 is separated with the import 12 in valve body 1, and liquid flows into from import 12, enters row pressure breach 14, thus enters outlet 13; Solenoid valve quits work, coil 6 power-off, and dynamic iron core 7 is due to gravity, and naturally fall, big spring 9 and little spring 8 act on and being compressed downwards by dynamic iron core 7, prevent liquid from flowing out.
Compared with prior art, the utility model has the advantage of: the utility model, by arranging big spring and little spring, improves the working life of spring; By arranging row pressure breach, for reducing the fashionable pressure to dynamic iron core of liquid stream; By arranging divided magnetic ring, for reducing noise and vibration; By arranging rubber tip, for improving sealing and working life, this practical design is reasonable, can large-scale promotion.
