概述

    该阀结构设计新颖合理，形体小、重量轻，密封性能良好，流通能力强流阻小．具有缓闭消声、无振动、无噪音功能。可根据不同的水况调节优良的缓闭时间，消除水锤。主要用于高层建筑及消防系统等给排水管道上，安装在水泵的出口处，用以截断介质的回汉，消除破坏性水锤，保证管路、水泵的安全运行，具有较好的节能效果。

Overview

The valve is featured by original structure, reasonable design,small profile, lightweight, outstanding sealing performance, strong circutating capability, little flow resistance, slow shut, noise elimina-tion, no vibration and noise. Functioned to effect optimal time for slow shut and for eliminating water hammer according to different occasions, triis valve is mainly used in water supply and drainage pipeline in highrises and fire control system, and mounted at the out-led of pump to cut off backflow of medium, eliminate destructive wa-ter hammer, ensure the safe operation of pipeline and pump, and ac-tualize distinguished energy-saving effect.
