Embodiment
Below in conjunction with accompanying drawing the utility model level is further described.
As shown in Figure 1, the described a kind of heavy caliber of the utility model is often opened direct action solenoid valve, comprises valve body 1, and valve gap 12 and electromagnetic switch component also are that valve body 1, valve gap 12 and electromagnetic switch component constitute the utility model agent structure.
Said valve gap 12 is located on the valve body 1, and it forms cavity between the two, is provided with valve film 2 between said valve body 1 and the valve gap 12.Said valve film 2 is divided into upper chamber 24 and lower chambers 22 with cavity, and place, said valve film 2 outers is provided with throttle orifice 25, and throttle orifice 25 is communicated with upper chamber 24 and lower chambers 22, plays the effect of pressure reduction between balance upper chamber 24 and the lower chambers 22.
Said electromagnetic switch component is located on the valve gap 12; Particularly; Said electromagnetic switch component comprises coil carrier 14, and coil carrier 14 outer periphery have coil 8, is provided with moving iron core 10 and static iron core 6 in coil carrier 14 inner chambers from top to bottom successively; Said moving iron core 10 bottoms are fixedly connected with decides plug 7, decides plug 7 lower ends and can move up and down and pass static iron core 6 and be connected with sealed core 11.
Said sealed core 11 is provided with Returnning spring 5 with valve gap 12, and it mainly acts on is under the situation of coil 8 outages, effectively helps moving iron core 10 self-returns.
Said sealed core 11 bottoms are provided with sealing gasket 13, and said valve film 2 is provided with pressure relief device, the corresponding setting with pressure relief device of said sealing gasket 13.Particularly, said pressure relief device comprises the pallet 3 of being with relief hole 23, and said valve film 2 is provided with through hole 28, and said through hole 28 is communicated with relief hole 23 and valve port 26, said sealing gasket 13 and relief hole 23 corresponding settings.Said pallet 3 is the chief component of pressure relief device still not, and helps the effective closure between valve film 2 and the valve port 26.The diameter of said relief hole 23 is greater than the diameter of throttle orifice 25, and its effect is to make the pressure of upper chamber 24 and lower chambers 22 reach balance rapidly, effectively realizes separating between valve film 2 and the valve port 26.
