ATOS先导型溢流阀 Pilot-operated Pressure Relief Valve
先导型溢流阀有多种结构是一种典型的三节同心结构先导型溢流阀,它由先导阀(Pilot Valve)和主阀(Main Valve)两部分组成。锥式先导阀1、主阀芯上的阻尼孔(固定节流孔)5及调压弹簧9一起构成先导级半桥分压式压力负反馈控制,负责向主阀芯6的上腔提供经过先导阀稳压后的主级指令压力P2。主阀芯是主控回路的比较器,上端面作用有主阀芯的指令力P2A2,下端面作为主回路的测压面,作用有反馈力P1A1,其合力可驱动阀芯,调节溢流口的大小,zui后达到对进口压力P1进行调压和稳压的目的
[1]1—锥阀(Pilot Valve)(先导阀);2—锥阀座(Poppet Seat);3—阀盖(Valve Cap);4—阀体(Valve Body);5—阻尼孔(Orifice);6—主阀芯(Main Spool);7—主阀座(Main Valve Seat);8—主阀弹簧(Main Spring);9—调压(Adjustment Spring) (先导阀)弹簧;10—调节螺钉;11—调节手轮。
工作时,液压力同时作用于主阀芯及先导阀芯的测压面上。当先导阀1未打开时,阀腔中油液没有流动,作用在主阀芯6上下两个方向的压力相等,但因上端面的有效受压面积A2大于下端面的有效受压面积A1,主阀芯在合力的作用下处于zui下端位置,阀口关闭。当进油压力增大到使先导阀打开时,液流通过主阀芯上的阻尼孔5、先导阀1流回油箱。由于阻尼孔的阻尼作用,使主阀芯6所受到的上下两个方向的液压力不相等,主阀芯在压差的作用下上移,打开阀口,实现溢流,并维持压力基本稳定。调节先导阀的调压弹簧9,便可调整溢流压力。
