moog穆格伺服阀G761-3009B由于电磁铁推力的限制,在大于63L/min的液压系统中,一般不再选用直推式的电磁换向阀,而选用通过流量较大的电液换向阀。电液换向阀的原理是:控制油通过电磁先导阀到达电液阀主阀芯的两端(即电液换向阀主阀体两端盖侧),通过电磁先导阀的换向,来实现主阀芯的左右移动,从而开通或切断通往执行元件的油路,使执行元件运行或停止。但在打开或切断油路的瞬间,系统中会产生相当大的冲击,这种冲击会极大影响液压系统中液压元件和密封件的使用寿命。为了减小及至消除由此引起的液压冲击,最简单的办法是在该电液阀下面叠加一个P口节流阀或进油节流式双单向节流阀、出油节流式双单向节流阀,以延长阀芯的换向及复位时间,从而到降低液压冲击的目的。下面就以弹簧复位型、三位四通中封式电液压换向阀为例、对该三种叠加节流方式作简要说明。
