功能说明 Function description

S型单向阀的作用是使油液只能向一个方向流动。而另一个方向截止。当油液从P1腔进入。油液克服弹簧（3）的弹簧力使锥阀芯（2）右移. 从而使P1、P2腔沟通。当油液从P2向P1流动时. 锥阀芯（2）左移. 单向阀关闭 retz品牌 The function of the S-type check valve is to make the oil flow in only one direction. Cut off in the other direction. When oil enters from P1 chamber. The oil overcomes the spring force of the spring (3) and causes the cone valve element (2) to move to the right Thus P1 and P2 communicate. When the fluid flows from P2 to P1 The cone valve element (2) moves to the left Check valve closed

对于无弹簧的单向阀、安装位置应保证阀芯能在自身重力作用下处于关闭位置 For the one-way valve without spring, the installation position shall ensure that the valve core can be in the closed position under its own gravity
