解读为什么泵出口不装“止回阀”容易产生水锤?   发布时间:16-06-10

  

微阻缓闭止回阀--概述

 

HH44X/T/H 型微阻缓闭止回阀用于给排水管道,安装在水泵出口处用来防止介质逆流和消除破坏性水锤,并能有效地减少阀门关闭水锤压力,可保障管网安全运行。 

 

微阻缓闭止回阀--特点

 

微阻缓闭止回阀具有阀瓣轻、开度大、节电效果显著,流体阻力小,水锤消除机构设计新颖,密封性能稳定可靠、耐磨损、使用寿命长、运行平稳、无振动、无噪声等特点。 

静音式止回阀--概述

 

H42T/DRVZ静音止回阀由阀体、阀座、导流体、阀瓣、轴瓦及弹簧等零件组成。内部流道采用流线型设计,压力损失极小,阀瓣启闭行程很短,停泵启闭行程很短,停泵时可快速关闭,防止巨大的水锤声,形成静音效果。主要用于给水、排水、消防、暖通系统,可安装于水泵出口处,以防止介质倒流及水锤对泵的损坏。      

微阻缓闭蝶型消声止回阀--概述

 

HH47X 微阻缓闭蝶型消声止回阀主要用于工业循环供排水、污水外理厂以及高层住楼和高级宾馆加压输出水泵的出品处,防止管网中介质流, 自动消除破坏性水锤,从而保水泵和管路不受损坏。在设计上充分考虑了使用环境的要求,曾多次进行技术改造。HH47X型微阻缓闭式蝶形止回阀该产品结构新 颖、体积小、流体阻力小、运行平稳、密封可靠、耐冲刷、耐磨损、缓冲性能好等特点。
