rexroth伺服阀*现货力士乐电磁阀力士乐中国 rexroth伺服阀原理：典型的伺服阀由永磁力矩马达、喷嘴、档板、阀芯、阀套和控制腔组成(见图)。当输入线圈通入电流  伺服阀
时，档板向右移动，使右边喷嘴的节流作用加强，流量减少，右侧背压上升；同时使左边喷嘴节流作用减小，流量增加，左侧背压下降。阀芯两端的作用力失去平衡, 阀芯遂向左移动。高压油从S流向C2，送到负载。负载回油通过 C1流过回油口，进入油箱。阀芯的位移量与力矩马达的输入电流成正比，作用在阀芯上的液压力与弹簧力相平衡，因此在平衡状态下力矩马达的差动电流与阀芯的位移成正比。如果输入的电流反向，则流量也反向。表中是伺服阀的分类。   伺服阀主要用在电气液压伺服系统中作为执行元件（见液压伺服系统）。在伺服系统中，液压执行机构同电气及气动执行机构相比，具有快速性好、单位重量输出功率大、传动平稳、抗干扰能力强等特点。另一方面，在伺服系统中传递信号和校正特性时多用电气元件。因此，现代高性能的伺服系统也都采用电液方式，伺服阀就是这种系统的必需元件。   伺服阀结构比较复杂，造价高，对油的质量和清洁度要求高。新型的伺服阀正试图克服这些缺点，例如利用电致伸缩元件的伺服阀，使结构大为简化。另一个方向是研制特殊的工作油（如电气粘性油）。这种工作油能在电磁的作用下改变粘性系数。利用这一性质就可通过电信号直接控制油流。
