关于跳汰机的整机自动化方案已有过许多，但事实上，影响跳汰机自动化实现的关键——风阀控制自动化，却还未有过可行的方案，更未有过实用的设备。针对这种情况，文章从分析跳汰机风阀动作的过程开始，寻求实现风阀自动控制的实用方法
There are many complete machine automation solutions for the jig. However, in fact, the key to automating the jig automatization is the automation of the air valve control. However, no feasible solution has been put forward and more practical equipment has not been available yet. In view of this situation, the article begins with the process of analyzing the action of the jig valve and seeks for a practical method of automatic control of the damper
