带集成式放大板比例阀

首先，比例阀必须有一个配套的放大器，它接受来自于计算机，或者PLC，或者电位器（滑动变阻器）的控制信号，把0-20毫安微弱的信号放大到0-800毫安。计算机的信号太弱了。

然后，放大器把放大的信号传送到电磁阀度，电磁阀依据传来的信号大小，克服弹簧力，调节推杆的行程，输出流量大约知1升/分钟,压力随信号变化的控制油。

再后，控制油到达主阀芯的两端，依据不同的压力，推动阀芯移动相应的行程，因为阀芯本身有锥度的台阶，与阀体组合，不同的行程得到不道同的过流面积，再入版口压力稳定的情况下，得到不同的流量。最终实现比例功能。

比例阀是由计算机（或其他），放大器，比例电磁铁，锥度台阶的阀芯，入口压力补偿阀（单联可以不要），梭阀，内置卸荷阀（把多余的流量送回油箱）等构成的一个完整的体权系。才能真正实现比例功能。
