氨用止回阀，氨气逆止阀是一种自动工作的单向阀, 阀瓣利用流体压差和自身的重量来动作,保护阀门及管道，适用氨气、氨液管道控制接通和截断管路介质的启闭装置，阻止介质逆流Ammonia check valve is an automatic one-way valve that uses fluid pressure difference and its own weight to operate the valve disc, protecting the valve and pipeline. It is suitable for controlling the opening and closing devices of connecting and cutting off pipeline media in ammonia and ammonia liquid pipelines, and preventing the reverse flow of media
进口氨用止回阀 氨气逆止阀应用
氨用止回阀（氨气逆止阀）适用于城市燃气，液氨，液化气等管道，也使用于炼油厂，石油化工厂，火力发电厂的冷却系统，作为控制介质逆流的启闭装置 RETZ Ammonia check valve (ammonia check valve) is applicable to urban gas, liquid ammonia, liquefied gas and other pipelines, and also used in the cooling system of refineries, petrochemical plants, and thermal power plants as the opening and closing device to control the reverse flow of the medium
进口氨用止回阀 氨气逆止阀主要特点DESIGN FEATURES
1、旋启式结构：阀瓣利用流体压差和自身重力实现旋转运动，流阻系数小，适用于大部分的贮罐区垂直管路上，自动阻止介质逆流，***上游设备 Swing structure: the valve clack uses the fluid pressure difference and its own gravity to realize rotary movement, with small flow resistance coefficient, which is applicable to most vertical pipelines in the tank area, automatically prevents the medium from flowing backward, and ensures the upstream equipment
注∶本阀可垂直水平安装，垂直安装介质必须有下向上 Note: The valve can be installed vertically and horizontally, and the vertical installation medium must be downward and upward
2、升降式结构：阀瓣利用流体压差和自身的重量实现升降，适用于水平管路上，自动阻止介质逆流，保护上游设备 Lifting structure: the valve clack uses the fluid pressure difference and its own weight to achieve lifting, which is suitable for horizontal pipelines, automatically prevents the medium from flowing backward, and protects upstream equipment
注∶本阀在管路上，只能水平安装 Note: This valve is installed horizontally on the pipeline only
3、立式结构：阀瓣利用流体压差和自身的重量实现升降，适用于大部份的罐区垂直管路上，自动阻止介质逆流，保护上游设备 Vertical check structure: the valve clack uses the fluid pressure difference and its own weight to achieve lifting and lowering, which is applicable to most of the vertical pipelines in the tank farm. It can automatically prevent the reverse flow of media and protect upstream equipment
注∶本阀只能垂直安装，介质有下向上 Note: The valve can only be installed vertically, and the medium is downward and upward
