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。
