The additional magnetic force that the solenoid valve of the present embodiment is generated by permanent magnet makes the starting current of solenoid valve and maintains electricity
Stream is substantially reduced, to achieve the purpose that reduce power consumption.
With regard to the solenoid valve of the present embodiment, its working principle is explained as follows below:
When dynamic iron core 3 is separated with armature 9, solenoid valve is in close state.It powers to the actuating coil of coil windings 2,
Dynamic iron core 3 is mobile to 9 direction of armature, and when dynamic iron core 3 and the actuation of armature 9, solenoid valve is in the conductive state.To coil windings 2
Maintenance coil power supply, actuating coil power-off, dynamic iron core 3 and armature 9 maintain attracting state, electromagnetism in the case where smaller magnetic force
Valve is held on.When solenoid valve is closed, permanent magnet 4 and sealing plate 5 and air packing 8 apart from farther out, permanent magnet to sealing plate 5 and
8 attraction of air packing is very small, therefore it is very small to the envelope valve pressure influence of elastic component 7.After solenoid valve starting, in dynamic iron
During core 3 is moved to 9 direction of armature, permanent magnet 4 follows dynamic iron core 3 to move together.When permanent magnet 4 is from sealing plate 5
Distance is more and more closer, and the attraction that permanent magnet 4 generates is increasing, and magnetic attracting force is inversely proportional with distance.It is moved in dynamic iron core 3
It attached the magnetic attracting force of permanent magnet 4 in dynamic process, the magnetic force of generation required by actuating coil can be subtracted in this way
It is small, that is, reduce the starting current of solenoid valve.Suction after dynamic iron core 3 and armature 9 are attracted between both reaches maximum, in this way
The magnetic force for maintaining generation required by coil can reduce when solenoid valve maintains, i.e. maintenance electric current can reduce, and can be dropped with this
The maintenance power consumption of low solenoid valve.
The magnetic intensity of fixed permanent magnet 4, it is adjustable by adjusting the minimum distance between permanent magnet 4 and sealing plate 5
The size of attraction between permanent magnet 4 and sealing plate 5 or stand frame 1, limit of the distance by distance between dynamic iron core 3 and armature 9
System, drags between pad 6 and sealing plate 5 that there are gaps when must assure that actuation, so that dynamic iron core 3 is contacted with armature 9, make maintenance electromagnetism
The magnetic attracting force of valve in the open state reaches maximum, and greatest attraction forces are less than spring force, after coil blackout
Valve can close under spring force.
Embodiment two: the present embodiment provides a kind of gas-cookers, have the solenoid valve as described in embodiment one, can drop
Low-dimensional holds power consumption, uses the time conducive to extension battery.Due to solenoid valve, its specific structure feature has carried out in example 1
In detail, it clearly describes, is thus no longer repeated in the present embodiment, to save space.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
