概述

H76X/H(DDCV系列)型閥門(mén)主要由閥體、閥瓣（閥桿）及彈簧等結(jié)構(gòu)組成，

由于閥瓣的關(guān)閉行短及彈簧作用可加強(qiáng)關(guān)閉效果．可減少水錘和水擊聲。

H46X/H是法蘭連接蝶型止回閥。這兩種閥門(mén)主要用于給水系統(tǒng)

．高樓建筑及工業(yè)區(qū)，其結(jié)構(gòu)長(zhǎng)度較一般的止回閥短

．對(duì)有安裝空間限制的場(chǎng)所便利。

Overview

H76X/H (DDCV Series)valves are mainly com-posed of body, disc(valve stem),

spring and etc.The short closing stroke of disc and function of spring may strengthen

closing effect and reduce the sound of water hammer and stamming. H46X/H are

flange connection butterfly check valves. These two types of valves are mainly used

in water sup-ply system, high-rises and industrial zones.Thanks to their shorter structural

length compared with ordinary check valves, they are especially ap-plicable for space-restricted locations.
