美国威格士VICKERS比例控制阀、*/上海一级合作商
美国威格士VICKERS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.液压伺服系统虽能满足其要求,而且精度很高,但对於大部分的工业来说,他们并不要求系统有如此高的品质,而希望在保证一定控制性能的条件下,同时价格低廉,工作可靠,维护简单,所以比例控制阀就是在这种背景下发展起来的.
比例控制阀可分为压力控制阀,流量控制及方向控制阀三类.
压力控制阀:用比例电磁阀取代引导式溢流阀的手调装置便成为引导式比例溢流阀,其输出的液压压力由输入信号连续或按比例控制.
流量:用比例电磁阀取代节流阀或调速阀的手调装置而以输入信号控制节流阀或调速阀之节流口开度,可连续或按比例地控制其输出流量.故节流口的开度便可由输入信号的电压大小决定.
方向控制阀:比例电磁阀取代方向阀的一般电磁阀构成直动式比例方向阀,其滑轴不但可以换位,而且换位的行程可以连续或按比例地变化,因而连通油口间的通油面积也可以连续或按比例地变化,所以比例方向控制阀不但能控制执行元件的运动方向外,还能控制其速度.
