A kind of self-holding electromagnetic valve, comprise valve body 1, valve body 1 is provided with import 11 and outlet 12, the top of valve body 1 is equipped with secured core assembly 2, this secured core assembly 2 is made up of the sleeve pipe 21 of the vertical perforate in center, the first fixed core 22 be made up of non-magnetic stainless steel material, the second fixed core 23 be made up of soft magnetic material and one piece of permanent magnet 24, permanent magnet 24 arranges between the first fixed core 22 and the second fixed core 23, second fixed core 23 is fixed on the upper end of described sleeve pipe 21, and the first fixed core 22 is fixed on described second fixed core 23; Movable core assembly 3 is provided with in the sleeve pipe 21 of secured core assembly 2, match with the valve port 13 in described valve body 1 in the lower end of this movable core assembly 3, spring 4 is arranged with outside the bottom of movable core assembly 3, upper end and the secured core assembly 2 of this spring 4 offset, and its lower end and movable core assembly 3 offset; Secured core assembly 2 is outside equipped with drum 51, this drum 51 is provided with winding 52 and coil magnetic guiding frame 53.
Wherein, the second fixed core 23 adopts soft magnetic material to make, and forms electromagnet after winding 52 is energized, thus can make movable core assembly 3 to move or moves down.And the first fixed core 22 adopts non-magnetic stainless steel material to make, such guarantee winding 52 is not short-circuited between the N pole of the electromagnet of formation and S pole after charging.This self-holding electromagnetic valve only uses one piece of permanent magnet 24, greatly reduces manufacture cost; Permanent magnet 24 is arranged in secured core assembly 2 in addition, can not cause the partial loss of magnetic force, ensure that the magnetic of permanent magnet 24 because of the high temperature in coil injection molding process, is conducive to the stability of self-sustaining state under solenoid valve powering-off state.
Nut 25 is screwed into from top to bottom, is fixed core assembly 2, coil magnetic guiding frame 53, drum 51 and winding 52 thus they is fixed.
In embodiment, permanent magnet 24 structure ringwise, the bottom of the first fixed core 22 fixes through the center of described permanent magnet 24 and the second fixed core 23.
In embodiment, the second fixed core 23 offers annular groove 23a, the top indent of sleeve pipe 21 also embeds in this annular groove 23a and fixes with the second fixed core 23.
When second fixed core 23 assembles with sleeve pipe 21, first the second fixed core 23 is inserted the top of sleeve pipe 21, then apply inside pressure in the periphery of annular groove 23a and make sleeve pipe 21 indent, in sleeve pipe 21 indent embedded rings connected in star 23a, thus the second fixed core 23 is firmly fixed together with sleeve pipe 21.
In embodiment, the second fixed core 23 offers seal groove 23b, the embedded periphery being shaped with the first seal ring 61, first seal ring 61 of sealing ring recess 23b coordinates with the inner wall sealing of described sleeve pipe 21.
The setting of the first seal ring 61 can ensure the sealing between the second fixed core 23 and sleeve pipe 21.
In embodiment, movable core assembly 3 is made up of movable core 31 and sealing gasket 32, and sealing gasket 32 is fixed on the lower end of described movable core 31, and the lower surface of sealing gasket 32 matches with described valve port 13.
The center of the lower end embedding sealing pad 32 of movable core 31, thus make sealing gasket 32 firmly be fixed on the lower end of movable core 31.
In embodiment, the lower end of sealing gasket 32 stretches out and forms annular edge 32a, and the lower end of spring 4 and the upper surface of this annular edge 32a offset.
In embodiment, between valve body 1 and described sleeve pipe 21, be provided with the second seal ring 62.
In embodiment, secured core assembly 2 is threaded with described valve body 1.
When secured core assembly 2 is screwed into the top of valve body 1 from top to bottom, compresses the second seal ring 62 thus ensure that the sealing between valve body 1 and secured core assembly 2; After secured core assembly 2 and valve body 1 have assembled, the lower surface of the second seal ring 62 is close to mutually with valve body 1 surface and is also formed sealing.
In embodiment, winding 52 is outside equipped with shell 71, and this shell 71 is provided with electric plug 72, and the setting of electric plug 72 is used for being connected with external power supply.
In embodiment, import 11 and outlet 12 are all shaped with connecting thread 1a.The setting party of connecting thread 1a into and out of the connection of medium pipeline.
Working principle:
During closed electromagnetic valve state, as shown in Figure 1, movable core assembly 3 is in decline state, the sealing gasket of its lower end 32 and valve port 13 close contact and closed by valve port 13, and now medium cannot flow to outlet 12 from import 11 through valve port 13.
When winding 52 moment forward energising, produce and the opposite polarity magnetic force of permanent magnet 24, make movable core assembly 3 moves, movable core assembly 3 moves past Compress Spring 4 in journey, and depart from valve port 13 thus valve port 13 is opened, namely solenoid valve is in open mode, now, as shown in Figure 5, medium enters in valve body 1 from import 11, then flows out valve body 1 through valve port 13 from outlet 12.After movable core assembly 3 moves, namely can stop energising, under the magnetic force of permanent magnet 24, movable core assembly 3 be in propradation all the time and with the adhesive of secured core assembly 2 phase; Therefore, when winding 52 does not continue energising, solenoid valve also can stay open state, has so greatly saved electric energy, reduces the user cost of equipment.
And will by closed electromagnetic valve time, only winding 52 oppositely need be energized, now winding 52 produces the magnetic force identical with permanent magnet 24 polarity, magnetic pole two like magnetic poles repel each other, under the effect of same polarity repulsive force and spring 4 spring force, movable core assembly 3 moves down and resets and closed by valve port 13, thus by closed electromagnetic valve.After winding 52 power-off, solenoid valve remains on closed condition, until winding 52 forward energising again.
Most preferred embodiment of the present utility model is illustrated, and the various change made by those of ordinary skill in the art or remodeling all can not depart from scope of the present utility model.
