工作原理
<Valve开有pressure>时
当通电的线圈，电枢组件的吸引到u的
芯管组件i和先导阀被打开。
当先导阀被打开，先导腔室内部的压力
减小，导致从进气压力的压力差。
然后，膜片组件e被取消，主阀处于
打开。
<Valve开时，没有任何压力或低分钟pressure>下
电枢总成u和膜片组件E的连接
彼此电梯弹簧！0。当衔铁组件
被吸引，隔膜组件拉和主阀
被打开。
<Valve closed>
当的线圈断电，衔铁装配ü回报
回位弹簧r和先导阀的反力被关闭。
当先导阀是关闭的，先导腔室内部的压力
增加，导致从进气压力的压力差
丢失和主阀关闭。

Working principles
<Valve opened – when there is pressure>
When the coil o is energized, the armature assembly u is attacted into
the core of the tube assembly i and the pilot valve is opened.
When the pilot valve is opened and the pressure inside the pilot chamber
decreases, resulting in the pressure difference from the inlet pressure.
Then the diaphragm assembly e is lifted and the main valve is
opened.
<Valve opened – when there is no pressure or under low minute pressure>
The armature assembly u and the diaphragm assembly e are connected
with each other with the lift spring !0. When the armature assembly
is attracted, the diaphragm assembly is pulled up and the main valve
is opened.
<Valve closed>
When the coil o is de-energized, the armature assembly u returns by
the reacting force of the return spring r and the pilot valve is closed.
When the pilot valve is closed, the pressure inside the pilot chamber
increases, resulting that the pressure difference from the inlet pressure
is lost and the main valve is closed.
