M-SR30KE05-1X/  REXROTH单向阀，德国力士乐REXROTH全新原装进口品牌，质量保证，现货库存价格优势销售；

单向阀是气流只能一个方向流动而不能反向流动的方向控制阀。其工作原理与液压单向阀一样。压缩空气从P口进入，克服弹簧力和摩擦力使单向阀阀口开启，压缩空气从P流至A；当P口无压缩空气时，在弹簧力和A口(腔)余气力作用下；阀口处于关闭状 态，使从A至P气流不通。单向阀应用于不允许气流反向流动的场合，如空压机向气罐充气 时，在空压机与气罐之间设置一单向阀，当空压机停止工作时，可防止气罐中的压缩空气回流 到空压机。单向阀还常与节流阀、顺序阀等组合成单向节流阀、单向顺序阀使用。

单向阀又称止回阀或逆止阀。用于液压系统中防止油流反向流动,或者用于气动系统中防止压缩空气逆向流动。

单向阀又称止回阀或逆止阀。用于液压系统中防止油流反向流动,或者用于气动系统中防止压缩空气逆向流动。
单向阀有直通式和直角式两种。直通式单向阀用螺纹连接安装在管路上。直角式单向阀有螺纹连接、板式连接和法兰连接三种形式。液控单向阀也称闭锁阀或保压阀，它与单向阀相同，用以防止油液反向流动。但在液压回路中需要油流反向流动时又可利用控制油压，打开单向阀，使油流在两个方向都可流动。液控单向阀采用锥形阀芯，因此密封性能好。在要求封闭油路时，可用此阀作为油路的单向锁紧而起保压作用。液控单向阀控制油的泄漏方式有内泄式和外泄式二种。在油流反向出口无背压的油路中可用内泄式；否则需用外泄式，以降低控制油压力。

M-SR30KE05-1X/  REXROTH单向阀

对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(throttle 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。节流阀供在压力降极大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－即所谓汽蚀现象。为了尽量减少汽蚀影响，阀瓣采用耐汽蚀材料（合金钢制造）并制成顶尖角为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。
