PARKER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,或者用于气动系统中防止压缩空气逆向流动。
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。
安装位置
单向阀就是止回阀 旋启式止回阀安装位置不受限制,通常安装于水平管路,但也可以安装于垂直管路或倾斜管路上。
