威格士节流阀DGMC-5-AT-FW-B-30 节流阀是通过改变节流截面或节流长度以控制流体流量的阀门。将节流阀和单向阀并联则可组合成单向节流阀。节流阀和单向节流阀是简易的流量控制阀,在定量泵液压系统中,节流阀和溢流阀配合,可组成三种节流调速系统,即进油路节流调速系统、回油路节流调速系统和旁路节流调速系统。节流阀没有流量负反馈功能,不能补偿由负载变化所造成的速度不稳定,一般仅用于负载变化不大或对速度稳定性要求不高的场合
节流阀的性能要求是:
·流量调节范围大,流量一压差变化平滑;
·内泄漏量小,若有外泄漏油口,外泄漏量也要小;
·调节力矩小,动作灵敏。
节流阀(Choke valve)的外形结构与截止阀并无区别,只是它们启闭件的形状有所不同。
节流阀的启闭件大多为圆锥流线型,通过它改变通道截面积而达到调节流量和压力。节流阀供在压力降的情况下作降低介质压力之用。介质在节流阀瓣和阀座之间流速很大,以致使这些零件表面很快损坏-即所谓气蚀现象。为了尽量减少气蚀影响,阀瓣采用耐气蚀材料(合金钢制造)并制成顶jian角为140~180的流线型圆锥体这还能使阀瓣能有较大的开启高度,一般不推荐在小缝隙下节流。由于节流阀的流量不仅取决于节流口面积的大小,还与节流口前后的压差有关,阀的刚度小,
故只适用于执行元件负载变化很小且速度稳定性要求不高的场合。DGMA-3-B-10
