Mixed flow ratio controller system and flow distribution method thereof

A mixed flow ratio controller system is provided that includes an inlet configured to receive a total inlet fluid flow and three or more distribution channels. Each of the more than three distribution channels has a respective variable flow control valve and delivers a respective portion of the total inlet fluid flow. The mixed flow ratio controller also includes a controller operably connected to the respective variable flow control valves. The controller is configured to control the flow of at least the first distribution channel according to a predetermined flow ratio of the inlet fluid flow in a flow ratio control mode; controlling the flow of at least the second distribution channel in a flow control mode or a pressure control mode; and control the third distribution channel in an overflow mode. 提供了一种混合流量比率控制器系统，其包括：被配置为接收总的入口流体流量的入口以及三个以上分配通道。三个以上分配通道中的每个分配通道都具有相应的可变流量控制阀并且输送总的入口流体流量的相应的部分。混合流量比率控制器还包括可操作地连接到相应的可变流量控制阀的控制器。控制器被配置为按照流量比率控制模式根据入口流体流量的预定流量比率来控制至少第一分配通道的流量；在流量控制模式或压力控制模式下控制至少第二分配通道的流量；并且在溢流
