The invention relates to a priority control system, and discloses an action priority control system and an action priority control method.The action priority control system comprises a plurality of action links arranged in sequence, an oil inlet oil way, a pilot oil inlet oil way, a pilot oil return oil way and a controller, and the oil inlet oil way, the pilot oil inlet oil way and the pilot oil return oil way are communicated with the action links. Each action unit comprises a main valve connected with an executing mechanism, a control port of the main valve is connected with the pilot oil inlet path and the pilot oil return path through a pilot valve, and a priority control valve is arranged on the oil inlet path between every two adjacent action units. The controller controls the opening degree of a valve port of the priority control valve according to pressure signals in front of and behind the priority control valve so as to control flow distribution to the action links ranked in front. The flow distribution device can adapt to frequent changes of loads in actual work so as to accurately distribute flow, and is good in controllability, high in working efficiency, small in energy consumption and simple in structure.
本发明涉及优先控制系统，公开了一种动作优先控制系统及动作优先控制方法，该动作优先控制系统包括多个顺序排布的动作联、连通各所述动作联的进油油路、先导进油油路、先导回油油路和控制器，所述动作联包括与执行机构连接的主阀，所述主阀的控制口通过先导阀与所述先导进油油路和先导回油油路连接，相邻所述动作联之间的所述进油油路上设置有优先控制阀，在复合动作工况下，所述控制器根据所述优先控制阀前后的压力信号，控制所述优先控制阀的阀口开度，以控制向排序在前的所述动作联分配流量。能够适应实际工作中负载的频繁变化而进行流量的精确分配，操控性好、工作效率高、能耗小、结构简单。
