进口气动梭阀

简要描述:RETZ品牌 进口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 The inlet pneumatic shuttle valve forces the piston to reciprocate with compressed air to open and close the valve. The medium pressure acts on the valve seat, and the piston is almost free from resistance interference, so the valve can be quickly opened or closed. The improved valve internal structure makes the medium flow state better and the pressure loss smaller

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

关阀.png

关阀

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。

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。

Close the valve

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.

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.

开阀

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。

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。

Open valve

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.

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。

characteristic

Small size, beautiful appearance and long service life

Stainless steel valve body is adopted, with high-grade appearance and corrosion resistance

The piston and seal are combined into one, which is simple and reliable, and has a long service life

It can be installed in any direction.

As the medium pressure acts on the valve seat, the piston is hardly disturbed by resistance, so the switching speed is fast and the pressure loss is small.

Excellent vacuum sealing performance, which can be used in vacuum pipelines.
