概述

    該閥結(jié)構(gòu)設(shè)計(jì)新穎合理,形體小、重量輕,密封性能良好,流通能力強(qiáng)流阻小.具有緩閉消聲、無(wú)振動(dòng)、無(wú)噪音功能。可根據(jù)不同的水況調(diào)節(jié)優(yōu)良的緩閉時(shí)間,消除水錘。主要用于高層建筑及消防系統(tǒng)等給排水管道上,安裝在水泵的出口處,用以截?cái)嘟橘|(zhì)的回漢,消除破壞性水錘,保證管路、水泵的安全運(yùn)行,具有較好的節(jié)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.
