The invention belongs to the technical field of self-control valves, and discloses a hydraulic follow-up self-control valve, a control system, a control method and a follow-up self-control jack. The control system comprises a hydraulic follow-up self-control valve, a first connector and a second connector of the hydraulic follow-up self-control valve are connected with a liquid inlet cavity and a first liquid return cavity of a follow-up hydraulic component, and a second connector of the hydraulic follow-up self-control valve is connected with a second liquid return cavity of a follow-up hydraulic component. And a third interface and a fourth interface of the hydraulic follow-up automatic control valve are respectively connected with a second liquid inlet cavity and a second liquid return cavity of the driving hydraulic component between the hydraulic control lock and the main control reversing valve. The hydraulic follow-up self-control valve control system is integrated on the jack, the hydraulic follow-up self-control valve is integrated on the jack, follow-up and self-locking functions of the follow-up jack can be achieved without manual operation, and the follow-up jack can automatically switch working conditions along with switching of working conditions of a driving hydraulic component.

    本发明属于自控阀技术领域,公开了液压随动自控阀、控制系统、控制方法及随动自控千斤顶。所述控制系统包括:搭载有所述液压随动自控阀,所述液压随动自控阀的第一接口、第二接口连接随动液压部件的进液腔、第一回液腔,所述液压随动自控阀的第三接口、第四接口分别连接液控锁和主控换向阀之间的主动液压部件的第二进液腔、第二回液腔。本发明提供了一种液压随动自控阀控制系统,集成到千斤顶上,液压随动自控阀集成到千斤顶上,无需人工操作即可实现随动千斤顶的随动与自锁功能,也可实现随动千斤顶随主动液压部件工况的切换而自动切换工况。
