德國REXROTH力士樂先導式電磁閥: 原理:通電時,電磁力把先導孔打開,上腔室壓力迅速下降,在關 閉件周圍形成上低下高的壓差,流體壓力推動關閉件向上移動,閥門打開;斷電時,彈簧力把先導孔關閉,入口壓力通過旁通孔迅速腔室在關閥件周圍形成下低上高的壓差,流體壓力推動關閉件向下移動,關閉閥門。 特點:流體壓力范圍上限較高,可任意安裝(需定制)但必須滿足流體壓差條件。 REXROTH電磁閥是用電磁控制的工業(yè)設備,是用來控制流體的自動化基礎元件,屬于執(zhí)行器,并不限于液壓、氣動。用在工業(yè)控制系統(tǒng)中調(diào)整介質(zhì)的方向、流量、速度和其他的參數(shù)。力士樂電磁閥可以配合不同的電路來實現(xiàn)預期的控制,而控制的精度和靈活性都能夠保證。電磁閥有很多種,不同的電磁閥在控制系統(tǒng)的不同位置發(fā)揮作用,zui常用的是單向閥、安全閥、方向控制閥、速度調(diào)節(jié)閥等。
