工作原理
本阀门共有三处通孔，可实现换向分流或混合功能，在一定程度上可替代两通截止阀。阀门在非工作状态时，由于弹簧力的作用，阀门C端常闭，B端常开；当执行器活塞被压缩气体作用时，阀门C端打开，B端关闭。双作用形式时，靠压缩空气控制阀门开启或关闭。
The valve has three through holes,which can realize the function of reversing shunt or mixing,and can replace the two-way stop valve to a certain extent.When the valve is in non-working state,the C end of the valve is normally closed and the B end is normally open due to the action of the spring force.When the actuator piston is acted on by compressed gas,the Cend of the valve is opened and the B end is closed.In double- acting form,the valve is opened or closed by compressed air control.
