ODE導(dǎo)活塞式電磁閥選型參數(shù)
與此同時(shí)柱塞對(duì)隔膜施加直接力，輔助它開(kāi)放。
這個(gè)力和壓力的不平衡的總和在隔膜的兩側(cè)引起膜片移動(dòng)并打開(kāi)主孔。
在該系列的電磁閥中不能有zui小值
入口管和出口管之間的壓差確保電磁閥的正常工作。
但是，入口和出口之間的壓力差過(guò)大，正常情況下為2路閉合的直接作用電磁閥，
導(dǎo)致打開(kāi)飛行員所需的力增加孔，因此如果該壓力差大于螺線(xiàn)管的zui大值閥已經(jīng)被設(shè)計(jì)，
即使當(dāng)線(xiàn)圈通電時(shí)，后者也可以不打開(kāi)。
為了電磁閥的正確操作，并且為了避免隔膜的快速磨損，
是可取的，一旦開(kāi)始閥關(guān)閉，實(shí)際流量不高于Kv（即：流量通過(guò)閥，壓力損失為1巴）。
2 way normally closed direct acting solenoid valves have an inlet
pipe and a outlet pipe. The plunger, on which a sealing gasket
is mounted, provides directly for opening and closing the mainorifice.
主孔，在體內(nèi)，通過(guò)壓力之間的不平衡的作用打開(kāi)隔膜（或活塞）的上表面和下表面：
當(dāng)線(xiàn)圈不通電時(shí)，存在壓力下的流體腔室上方的膜片下面
隔膜有壓力只在外部的區(qū)域主孔：因此是膜片上的力的合力以便推動(dòng)它并關(guān)閉主孔口。

Notes:
In this solenoid valve family an increase in pressure causes an
increase in the force required to open the valve: if the pressure
difference between inlet and outlet is greater than the maximum
value for which the solenoid valve has been designed, the latter
may not open even with the coil energized.

 When the coil is not energized the plunger is in such a
position as to close the orifice thus preventing the flow of fluid.
When the coil is energized the plunger moves to such a position
as to open the orifice, permitting fluid flow.
