进口气动梭阀 气控快速开关二通阀 美国RETZ瑞茨

　　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 retzThe compressed air of the pneumatic shuttle valve forces the piston to moveback and forth, achieving the opening and closing of the valve. The mediumpressure acts on the valve seat, and the piston is almost unaffected byresistance, so the valve can quickly open or close. Improved valve internalstructure, 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。Whenthe "A" hole intake ("B" hole exhaust), the piston moves tothe "d'port and presses on the valve seat seal. At this time, the valve isclosed.

　　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。Thesingle acting normally closed spring is installed in the "A" endchamber. In case of non control, the piston is pressed on the valve seat, soits 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。Whenthe "B" hole intake ("a" hole exhaust), the piston shaftmoves from the valve seat to the "C" port and stops at the end of thestroke. 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。Thesingle acting normally open spring is installed in the "B" endchamber. In case of non control, the piston leaves the seat, so its mostcommonly used position is the open position.
