比例阀基本原理详解
BASIC SYSTEM
1) 一般认为一个简单的液压系统由油 箱（A）、电动机（B）、泵（C）、溢 流阀（D）、过滤器（E）、流量控制 阀（F）、方向控制阀（G）、和油缸 （H）组成。

2) 油缸的运动是由流量控 制阀（确定运动的速度） 和方向控制阀（油缸运动 的方向）控制。
在这个例子中，这个开关能够被转到全开 和全关的任一位置，来调整灯泡的亮度
In this case, the switch can be turned to any position between fully off and fully on to vary the brightness of the bulb.
In this case, the switch can be turned to any position between fully off and fully on to vary the brightness of the bulb.

SWITCHING SOLENOID VALVE
一个传统的电磁阀能够被认为是一个简单的开关阀。 A conventional solenoid valve can be thought of as a simple switching valve. 它可以被一些只有简单电流通断的开关的电设备来控制 It is controlled by some form of electrical device which simply switches the electrical current on or off.
In this case, the switch can be turned to any position between fully off and fully on to vary the brightness of the bulb.

当电磁阀得电时，油缸活塞将伸出和 回缩,其速度由流量控制阀确定，而电 磁阀不具有控制速度的能力。

A three position solenoid valve can: - extend the cylinder

A three position solenoid valve can: - extend the cylinder - retract the cylinder

SWITCHING SOLENOID VALVE
A conventional solenoid valve can be thought of as a simple switching valve. It is controlled by some form of electrical device which simply switches the electrical current on or off.
and in the other position it is switched on but there are no intermediate states.
然而众所周知，另一种形式的开关能够 用来控制灯泡，调光开关
However, another type of switch can be used for controlling a light bulb known as a dimmer switch.
BASIC SYSTEM
A three position solenoid valve can: - extend the cylinder - retract the cylinder - stop the cylinder
因此电磁阀的动作非常象一个电路中的开 关
在此位置灯是关闭状态.
... 在另外一个位置是开启状态，而 没有中间状态。
BASIC SYSTEM
1) 比例方向阀能够被看作与调光开 关具有同样功能。
A proportional directional valve can be thought of as the dimmer switch equivalent of an electrical switch.
2) 阀芯能够移动到在任一 位置，而不仅仅是三个不 连续的位置。
阀芯在离开中位的方向仍 然确定油缸运动的方向， 但阀芯离开中位的距离控 制活塞的速度。
BASIC SYSTEM
于是在实际上比例阀可以同时作为方 向阀和流量阀来使用。
So in effect the proportional directional valve is acting as both a directional valve and a flow control valve.
