The operation principle of the present embodiment normally open solenoid valve：
During normally open solenoid valve no power, in the presence of second spring 36 and piston spring 23, the lower sealing of seal member 2
Pad 22 departs from valve port 111, and needle 34 departs from the upper sealing gasket 20 of seal member 2, and medium can be from entering circulation road 110 through valve port
111 flow into out circulation road 112.
After normally open solenoid valve energising, dynamic iron core 32 overcomes the elastic force of second spring 36 to static iron core 33 under electromagnetic force
Mobile, meanwhile, the elastic force of the first spring 35 orders about needle 34 and moves down, until needle 34 lower end abuts to seal member
2 upper sealing gasket 20, needle 34 promotes seal member 2 to overcome the elastic force of piston spring 23 mobile to valve port 111, until sealing
The lower seal pad 22 of part 2 fits to valve port 111, needle at this moment 34 and seal member 2, seal member 2 and valve port 111 all in
Sealing state, but dynamic iron core 32 can also be mobile to static iron core 33 under electromagnetic force, until dynamic iron core 32 and static iron core 33
Adhesive completely, and in this course, because needle 34 has abutted to the upper sealing gasket 20 of seal member 2, needle 34 will not
Move still further below, so that forming certain interval between the step of the positive stop lug boss 340 of needle 34 and dynamic iron core 32 stepped hole.
After closing valve, due to the presence in this gap, after normally open solenoid valve again power-off valve opening, dynamic iron core 32 is under second spring 36 effect
When resetting upwards, needle 34 will not be driven immediately to move, and needle 34 could be driven after wanting the idle stroke of movement clearance generation, from
And decrease the impact to needle 34 for the dynamic iron core 32 during valve opening, lift valve opening performance.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model does not limit to
In this, it is familiar with this those skilled in the art and should be understood that this utility model includes but is not limited to accompanying drawing and specific embodiment party above
