概述

    該閥結構設計新穎合理，形體小、重量輕，密封性能良好，流通能力強流阻小．具有緩閉消聲、無振動、無噪音功能。可根據不同的水況調節優良的緩閉時間，消除水錘。主要用于高層建筑及消防系統等給排水管道上，安裝在水泵的出口處，用以截斷介質的回漢，消除破壞性水錘，保證管路、水泵的安全運行，具有較好的節能效果。

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.
