现货特价型号：R900925687 4WRAE10W1-30-22/G24N9K31/F1V 2台1充液门的结构
充液阀主要由控制活塞、缸体、阀体、阀座、主阀芯、卸荷闽等组成。根据需要，我们设计有带预卸荷阀和不带预卸荷阀的两种充液阀。如果采用系统卸压．即系统中设置了卸荷回路，则采用不带预卸荷阀的充液阀，这种情况尤其适用干大型液压机。Dg50～Dg125规格的充液阀的主阀芯与阀杆做成一体，即采用整体构造；Dg150～Dg350规格的充液阀的主阀芯与阀杆采用分体结构。SDV20-1B8B-1A F3 SDV20 1P11P 1A SDV20 1P10P 1A SDV20 1P11P 1A SDV20 1P11P 1B

2防松措施
参见图l充液阀结构原理图，a处防松采用GB858—76圆螺母用止动垫圈；b处安装螺钉的防松采用c船54一鼹单耳止动垫圈；c处主阀芯与阀杆之问的防松采用左旋、右旋螺母拧紧后点焊；d处卸荷阀盖的防松采用了弹簧垫圈及带孔螺栓用铁丝串联锁紧。
3主闷计算
已知当量通径Dg(m)，主阔开启行程h(m),阀口锥角2α =120。则：
当量通流面积Ag=πDg 2／4。主阀口直径。
4控制活塞计算
控制活塞直径应尽可能小，但必须满足两个条件：
1)当主缸油压为最大工作压力(p=2.5×107Pa)和控制油压为最小油压(pc=1.5×106Pa)时，控制活塞应能将充液阀中的卸载阀打开，即：
式中：dv-卸载阀口直径(m)；
Dc-控制活塞直径(m)。
(2)主缸活塞回程时充液阀的主阀芯不关闭，即：
