概述
H76X/H(DDCV系列)型閥門主要由閥體、閥瓣(閥桿)及彈簧等結構組成,
由于閥瓣的關閉行短及彈簧作用可加強關閉效果.可減少水錘和水擊聲。
H46X/H是法蘭連接蝶型止回閥。這兩種閥門主要用于給水系統
.高樓建筑及工業區,其結構長度較一般的止回閥短
.對有安裝空間限制的場所便利。
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.
