BOSCH-REXROTH插装阀/博世中国一级代理
BOSCH-REXROTH插装阀的内部结构可分滑阀位置反馈、载荷压力反馈和载荷流量反馈；阀的级数可分单级、双级和多级。在电液伺服阀中，将电信号转变为旋转或直线运动的部件称为力矩马达或力马达。力矩马达浸泡在油液中的称为湿式，不浸泡在油液中的称为乾式。其中以滑阀位置反馈、两级乾式电液伺服阀应用zui广。电液伺服阀的工作原理是力矩马达在线圈中通入电流后产生扭矩，使弹簧管上的挡板在两喷嘴间移动，移动的距离和方向随电流的大小和方向而变化。
BOSCH-REXROTH插装阀用进出口两端中心轴导向，启闭灵活，可水平定装或垂直安装。阀瓣采用弹簧加载，其快速关闭能有效地减小水锤压力，密封性能好，关闭无噪声。止回阀具有体积小、重量轻、流体阻力小、耐疲劳、寿命长等优点，产生的的作用是只允许介质向一个方向流动，而且阻止方向流动。通常止回阀是自动工作的，在一个方向流动的流体压力作用下，阀瓣打开；流体反方向流动时，由流体压力和阀瓣的自重合阀瓣作用于阀座从而切断流动。
