RETZ瑞茨品牌 进口气动梭阀 气控快速开关二通阀

品牌：RETZ瑞茨/我们一直致力于流体控制和测控领域的持续创新，始于2005……气动梭阀压缩空气迫使活塞往复运动，达到阀门的开启与关闭。介质压力作用在阀座上，活塞几乎不受阻力干扰，所以阀门可快速开或关。经改进的阀内结构，使介质流态更好，压损更小 retz The compressed air of the pneumatic shuttle valve forces the piston to move back and forth, achieving the opening and closing of the valve. The medium pressure acts on the valve seat, and the piston is almost unaffected by resistance, so the valve can quickly open or close. Improved valve internal structure, resulting in better fluid flow and reduced pressure loss

进口气动梭阀工作原理 Working principle of inlet pneumatic shuttle valve

1.关阀Close the valve

当"A"孔进气（"B"孔排气）时，活塞向"D'口移动并压在阀座密封上，此时阀门关闭。When the "A" hole intake ("B" hole exhaust), the piston moves to the "d'port and presses on the valve seat seal. At this time, the valve is closed.

单动常闭型的弹簧安装在"A"端腔室。在非控制时，活塞是压在阀座上，所以其常用的是关闭位。The single acting normally closed spring is installed in the "A" end chamber. In case of non control, the piston is pressed on the valve seat, so its most commonly used position is the closed position.

2.开阀Open valve

当"B"孔进气（"A"孔排气）时，活塞轴从阀座向℃"口方向移动并在行程末端停止，此时阀门开启。When the "B" hole intake ("a" hole exhaust), the piston shaft moves from the valve seat to the "C" port and stops at the end of the stroke. At this time, the valve is opened.

单动常开型的弹簧安装在"B"端腔室。在非控制时，活塞是离开座的，所以其常用的是开启位。The single acting normally open spring is installed in the "B" end chamber. In case of non control, the piston leaves the seat, so its most commonly used position is the open position.

进口气动梭阀特点 Features of imported pneumatic shuttle valve

体积小，外观美，寿命长

采用不锈钢阀体，外观高档，耐腐蚀

活塞与密封合二为一，简单可靠，具有超长使用寿命

可任意方向安装。

由于介质压力作用在阀座上活塞几乎不受阻力干扰，所以开关速度快，压损小。

耐真空密封性能佳，可用于真空管路。
