M-SR20KE05-1X插装式单向阀

结构原理

1）MK型单向节流阀 该阀是管式联接的单向节流阀，其节流口采用轴向三角槽式结构。旋转调节螺母3，可改变节流口通流面积的大小，以调节流量。正向流动时起节流阀作用；反向流动时起单向阀作用，这时由于有部分油液可在环形缝隙中流动，可以清除节流口上的沉积物。在阀体2左端有刻度槽，调节螺母3上有刻度，用以标志调节流量的大小。

2）F型准确节流阀 该阀主要由阀体1，调节件2和节流套3组成。在节流口4处实现对从A到B的流动的节流。转动节流杆5，可调节节流断面。由于节流口制成薄壁孔，故节流不易受温度的影响。

节流阀和单向节流阀是简易的流量控制阀，它们在定量泵液压系统中的主要作用是与溢流阀配合，组成三种节流调速系统：即进油节流调速系统、回油节流调速系统和旁路节流调速系统。对于执行元件要求往返节流调速的系统可使用两个单向节流阀。节流阀也在容积节流调速回路中使用。这种阀没有压力及温度补偿装置，不能自动补偿载荷及油液粘度变化时造成的速度不稳定，但其结构简单，制造和维护方便。所以在载荷变化不大或对速度稳定性要求不高的一般液压系统中得到广泛应用。

电磁阀由两个基本功能单元组成：电磁线圈和磁芯。包含一个或几个孔的阀体。当电线圈通电或断电时，磁芯的运转将导致流体通过阀体或被切断。电磁线圈被直接安装在阀体上，磁芯被封闭在密封管中，构成一个简洁，紧凑的组合。

力士乐REXROTH叠加式液控单向阀Z2S 10

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。
