本例是行程式控制连续往复动作回路应用示例。推拉式手动阀1供起动与停止用;行程阀4、10是控制行程用;小车13直接与气缸3连接;摇臂8是使横梁9升降。图示是小车向左开始移动状态,由摇臂与小车相连的横梁也随着向左移动。当挡块7碰到限位架11时,横梁停止左移,而小车继续向左移动,于是摇臂
This example is a stroke control continuous reciprocating motion circuit application example. Push and pull manual valve 1 for start and stop; stroke valve 4, 10 is used to control the travel; car 13 directly connected to the cylinder 3; The illustration shows the car moving to the left and the beam connected to the car by the rocker also moving to the left. When the stopper 7 hit the limit frame 11, the beam stops moving left, while the car continues to move to the left, then the rocker arm
