进口氨用止回阀 氨用逆止阀 美国RETZ瑞茨

　　品牌：RETZ瑞茨/美国，我们一直致力于流体控制领域的持续创新，始于2005……

　　氨用止回阀，an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an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 fluidpressure difference and its own weight to operate the valve disc, protectingthe valve and pipeline. It is suitable for controlling the opening and closingdevices of connecting and cutting off pipeline media in ammonia and ammonialiquid pipelines, and preventing the reverse flow of media

　　进口氨用止回阀 an气逆止阀应用

　　氨用止回阀（an气逆止阀）适用于城市燃气，液an，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 tourban gas, liquid ammonia, liquefied gas and other pipelines, and also used inthe cooling system of refineries, petrochemical plants, and thermal powerplants as the opening and closing device to control the reverse flow of themedium

　　进口氨用止回阀 an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，保证上游设备 Swing structure: the valve clack uses the fluid pressure differenceand its own gravity to realize rotary movement, with small flow resistancecoefficient, which is applicable to most vertical pipelines in the tank area,automatically prevents the medium from flowing backward, and ensures theupstream 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 verticalinstallation 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 pressuredifference and its own weight to achieve lifting, which is suitable forhorizontal 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 pressuredifference and its own weight to achieve lifting and lowering, which isapplicable to most of the vertical pipelines in the tank farm. It canautomatically 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 andupward
