介绍一种能够在工程机械液压系统中改变两个定量马达连接方式的液控换向阀。该阀阀芯在弹簧和液压油共同作用下,与阀体的相对位置发生改变,使阀体上油口的连接方式发生改变,从而能够方便地实现两个定量马达并联和串联交替变化。
This paper introduces a hydraulic control valve that can change the connection of two fixed motors in the hydraulic system of construction machinery. The valve spool in the spring and hydraulic oil together, the relative position of the valve body is changed, so that the connection of the valve port on the body changes, which can easily be achieved in parallel with two quantitative motor and series alternating changes.
