Hose nozzle, current can pass through water pipe 24 and be flowed out from delivery port 8, and magnetic valve is in open mode.After power-off, due to quiet iron
Core 6 has S poles all the time, and dynamic iron core 5, which remains unchanged, remains the magnetic of N poles, and magnetic valve remains on.
Need close valve when, coil 4 is reversely powered, electromagnetic force acting in opposition caused by coil 4 in dynamic iron core 5,
Plus the natural quality of the elastic force of back-moving spring 12, dynamic iron core 5 moves downward, and dynamic iron core 5 more leaves static iron core 6, the static iron core of S poles
The suction of the dynamic iron core 5 of 6 pairs of N poles is smaller, and static iron core 6 diminishes to the suction of dynamic iron core 5, the elastic force of back-moving spring 12, coil 4
Electromagnetic force makes valve element 2 block valve port 27 and water inlet pipe mouth 2 on valve element, and the elastic force output of back-moving spring 12 is maximum, moves
The seal head of iron core 5 also simultaneously blocks the water hole 30 on valve element 2.Because upper chamber 28 and lower chambers 29 are all the time by limbers
31 are connected, the hydraulic pressure and water inlet end in upper chamber 28 it is consistent, water pressure energy acts on the upper surface of valve element 2 from top to bottom, makes
Valve element 2 is firmly blocked in water inlet pipe mouth, and hydraulic pressure is bigger, and valve element 2 is better to the plugging effect of water inlet pipe mouth.After coil 4 powers off, move
Iron core 5 can also back-moving spring 12 elastic force and be uniformly distributed by the first magnetic inductive block 14 and act on dynamic iron core 5, make dynamic iron core 5
Keep that under stable state, and hydraulic pressure effect current location can be maintained at, magnetic valve is closed.
When magnetic valve is closed, the elastic force very little of back-moving spring 12, it is therefore desirable to when magnetic valve is opened, only need
Dynamic iron core 5 can be driven to moving on (static iron core 6) by wanting coil 4 to provide the smaller electromagnetic force on (static iron core 6).
