美国派克单向阀/PARKER单向阀型号单向阀又称止回阀或逆止阀。用于液压系统中防止油流反向流动。单向阀有直通式和直角式两种。直通式单向阀用螺纹连接安装在管路上。直角式单向阀有螺纹连接、板式连接和法兰连接三种形式。液控单向阀也称闭锁阀或保压阀,它与单向阀相同,用以防止油液反向流动。但在液压回路中需要油流反向流动时又可利用控制油压,打开单向阀,使油流在两个方向都可流动。液控单向阀采用锥形阀芯,因此密封性能好。在要求封闭油路时,可用此阀作为油路的单向锁紧而起保压作用。液控单向阀控制油的泄漏方式有内泄式和外泄式二种。在油流反向出口无背压的油路中可用内泄式;否则需用外泄式,以降低控制油压力。
止回阀用途广泛,有很多种类,下面说的是供水和热力常用的止回阀1、弹簧式:液体由下而上,依靠压力顶起弹簧控制的阀瓣,压力消失后,弹簧力将阀瓣压下,封闭液体倒流。常用于通径较小的止回阀。2、重力式:和弹簧式相似,依靠阀瓣的自身重力封闭,防止倒流。3、旋启式:液体在阀体内直通,依靠压力顶开一侧的旋转阀瓣,压力失去后,阀瓣依靠自重回位,反向的液体压力封闭阀瓣。4.塑料隔膜式:
