Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model normally open solenoid valve.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, normally open solenoid valve of the present utility model, comprise valve body 1, diaphragm 2, plunger tube 3, diaphragm spring 4, movable core 5 and pressing plate 6, described valve body 1 and plunger tube 3 are interconnected, and form cavity, described diaphragm 2 and pressing plate 6 are installed in cavity, and cavity are divided into upper plenum 7 and lower cavity 8; Described movable core 5 is positioned at plunger tube 3, and is flexibly connected with plunger tube 3; Described plunger tube 3 is also provided with positioning block 9 and the push rod 10 through positioning block 9, and described push rod 10 one end contacts with movable core 5, and the other end overlaps cored Sealing 11; Push rod spring 13 is also provided with between described push rod 10 and positioning block 9; Described diaphragm spring 4 is arranged between plunger tube 3 and pressing plate 6, and described diaphragm spring 4 is provided with " L " shape end 12, upper plenum 7 through described pressing plate 6, and is communicated with lower cavity 8 by described " L " shape end 12.
Also be provided with coil overmold 14, described coil overmold 14 is positioned at the upper end of this solenoid valve, after coil overmold 14 effect is energising, movable magnet is moved.
Also be provided with concentrating flux sleeve 15 and lower concentrating flux sleeve 16 between described plunger tube 3 and coil overmold 14, concentrating flux sleeve 15 length on lower concentrating flux sleeve 16 length >, object is to strengthen global magnetic field.
Be provided with magnetic shield 17 between described upper concentrating flux sleeve 15 and lower concentrating flux sleeve 16, magnetic shield 17 object carries out upper concentrating flux sleeve 15 and lower concentrating flux sleeve 16 every magnetic.
This solenoid valve top is magnet case 18 (magnet case is distributed in around coil) also, can add high magnetic fields.
Utility model works principle is simple: coil electricity produces magnetic field, is strengthened in magnetic field by magnet case, concentrating flux sleeve, and movable core under the influence of a magnetic field, overcomes ambient pressure and spring force down moves, and closes.During power-off, magnetic field dissipate, movable core resets under the effect of push rod spring and push rod, and solenoid valve is opened.
Normally open solenoid valve of the present utility model eliminates secured core, reduces cost of parts; During movable core adhesive, top and plunger tube inner bottom part do not touch, and eliminate the generation of noise, reduce cost of production; Diaphragm spring end penetrates pressing plate aperture, prevents pressing plate aperture incrustation scale from blocking, increases substantially the life-span.
In sum, above-mentioned mode of execution is not restricted mode of execution of the present utility model, and the modification that all those skilled in the art carry out on the basis of flesh and blood of the present utility model or equivalent deformation, all at technology category of the present utility model.
