电气比例阀

自动控制可分成断续控制和连续控制。断续控制即开关控制。气动控制系统中使用动作频率较低的开关式(ON-OFF)的换向阀来控制气路的通断。靠减压阀来调节所需要的压力，靠节流阀来调节所需要的流量。这种传统的气动控制系统要想要有多个输出力和多个运动速度，就需要多个减压阀、节流阀及换向阀。这样，不仅元件需要多，成本高，构成系统复杂，且许多元件都需要预先进行人工调节。电气比例阀控制属于连续控制，其特点是输出量随输入量的变化而变化，输出量与输入量之间存在一定的比例关系。比例控制有开环控制和闭环控制之分。

结构原理

输入信号加大，供气用电磁阀先导阀1换向，而排气用电磁先导阀7处于复位状态，则供气压力从SUP口通过阀1进入先导室5，先导室压力上升，气压力作用在膜片2的上方，则和膜片2相连的供气阀芯4便开启，排气阀芯3关闭，产生输出压力。此输出压力通过压力传感器6反馈至控制回路8。在这里，与目标值进行快速比较修正，知道输出压力与输入信号成一定比例为止，从而得到输出压力与输入信号的变化成比例的变化。由于没有喷嘴挡板机构，故阀对杂质不敏感，可靠性高。

比例控制阀主要用於开回路控制(open loop control);比例控制阀的输出量与输入信号成比例关系，且比例控制阀内电磁线圈所产生的磁力大小与电流成正比。

在传统型式的液压控制阀中，只能对液压进行定值控制，例如:压力阀在某个设定压力下作动，流量阀保持通过所设定的流量，方向阀对於液流方向通/断的切换。因此这些控制阀组成的系统功能都受到一些限制，随著技术的进步，许多液压系统要求流量和压力能连续或按比例地随控制阀输入信号的改变而变化。

电磁铁包括开关式和比例式两种，开关式电磁铁常被安装在换向阀上，用来控制阀的换向、系统的卸荷和加载等；比例式电磁铁安装在各类比例阀上，用来控制液流的方向、压力和流量。不少比例压力阀安装在电控变量泵上，可以控制泵的和流量和方向。

比例式电磁铁具有一个在其行程上，至少是在其工作行程内，电磁力很大程度上保持不变的特性

，以此区别于普通开关式电磁铁。这一吸力特性，是通过工作气隙的特殊造型和导磁体磁力的引导而形成。开关式和比例式电磁铁的差别并不完全取决于电磁铁本身，比例电磁铁通大电流时相当于开关式电磁铁，开关式电磁铁通不同的电流时也会产生不同的推力。

重锤杠杆式安全阀是利用重锤和杠杆来平衡作用在阀瓣上的力。根据杠杆原理，它可以使用质量较小的重锤通过杠杆的加大作用获得较大的作用力，并通过移动重锤的位置(或变换重锤的质量)来调整安全阀的开启压力。
