评论：当在可能产生腐蚀产物的设施处使用隔膜阀或任何带有软阀座材料的阀门时，采取防范措施来防止那些反应是非常重要的。
Comments: When using diaphragm valves or any valve with a soft seat material in a service where corrosion products can be produced, it is very important to take precautions to prevent those reactions.
当切断钢瓶和隔膜阀的连接时，两次关闭阀门和正确安装排气口密封是最重要的。
When disconnecting cylinders with diaphragm valves, it is most important to double close the valve and to properly install the outlet seal.
警告：要小心谨慎操作，避免紫色底漆或液状粘固剂流回到阀门内的隔膜或密封区域。
Caution: Exercise care to prevent purple primer or solvent cement from running back in the valve to the diaphragm or seating area.
因为阀门设计产生了基本的变化，以克服较早的隔膜阀的缺点，这些阀门被称为第二代隔膜阀。
These valves are referred to as second generation diaphragm valves because basic changes in the valve design have been incorporated to resolve the deficiencies of the earlier diaphragm valves.
因此，一个聚四氟乙烯隔膜不能用作配置三元乙丙橡胶阀内件的阀门的更换件。
Therefore, a PTFE diaphragm cannot be used as a replacement in an EPDM trimmed valve.
但是，一个三元乙丙橡胶隔膜可以用作配置聚四氟乙烯阀内件的阀门的更换件。
But an EPDM diaphragm may be used as a replacement in a PTFE trimmed valve.
本文介绍了进口隔膜式调节阀的结构，以及这种阀门的维护保养方法。
This article describes the structure of the imported pneumatic diaphragm regulating valve and maintenance method of this type of valve.
警告：不要让紫色底漆或液状粘固剂侵入阀门挡圈和隔膜区域。
Caution: Do not allow purple primer or solvent cement to migrate into the valve weir and diaphragm area.
当有流体通过阀门时，第一阀瓣开启从隔膜密封上离开。
With flow through valve, primary check opens away from diaphragm seal.
当流体通过阀门时，第一阀瓣开启，从隔膜密封上离开。
With flow through valve, primary disc opens away from diaphragm seal.
在一个不平衡的状况，允许为主线的压力，解除了主要的孔隔膜，从而打开阀门这个结果。
This results in an unbalanced condition which allows the main line pressure to lift the diaphragm off the main orifice and, thereby, open the valve.
相对发达国家而言，我国气动隔膜阀阀门行业还比较落后。
Relative to the developed countries, China's pneumatic diaphragm valve valve industry is still lag behind.
注：1、气动隔膜阀门尚可附装反馈信号、限位器和定位器，以适应自控、程控或调节流量的需要。
Note:1. Pneumatic diaphragm valve also can be installed feedback signal, limited machine or localizer in order to adapt to the requirements of automatic, programed control or flow rate adjustment.
警告：要小心谨慎操作，避免紫色底漆或液状粘固剂流回到阀门内的隔膜或密封区域。
Caution: Do not allow purple primer or solvent cement to migrate into the valve weir and diaphragm area.
该尺度适用于闸阀、截止阀、节流阀和隔膜阀等用阀门驱动装置于阀门的连接尺寸。
