叠加式液控单向阀的工作原理与一般液压阀基本相同,但在具体结构和连接尺寸上则不相同,它自成系列,每个叠加式液控单向阀既有一般液压元件的控制功能,又起到通道体的作用,每一种通径系列的叠加式液控单向阀其主油路通道和螺栓连接孔的位置都与所选用的相应通径的换向阀相同,因此同一通径的叠加式液控单向阀都能按要求叠加起来组成各种不同控制功能的系统。
叠加式液控单向阀主要由钢制阀体,一个或两个单向阀,先导级活塞组成.单向阀的主阀芯内有先导锥阀芯,通过它保证单向阀打开.当油液由A1流向A2,单向阀打开,同时先导级活塞被推至右位,通过先导锥阀芯的作用单向阀打开.

为确保锥阀正确到位关闭阀口,应使用Y型机能的换向阀,让活塞在中位,油口A1和B1接都接油箱。
