一 静音止回阀的概况
DRVZ静音止回阀主要是由阀体、阀座、导流体、阀瓣、轴承及弹簧等主要零件组成。DRVZ静音止回阀的内部流道采用流线型设计,压力损失极小,阀瓣启闭行程非常短,停泵时可以快速关闭,防止巨大的水锤声,并具有静音关闭的特点。河北华汇阀门有限公司生产的DRVZ静音式止回阀主要用于给排水、消防、暖通系统,可安装于水泵出口处,以防止倒流及水锤对水泵的损害,有效的保护了水泵的正常的运行。
二 静音止回阀的工作原理
本阀门在使用过程中,介质按图示箭头方向流动。1、当介质按规定方向流动时,阀瓣受介质力的作用,被开启;介质逆流时,因阀瓣自重和阀瓣受介质反向力的作用,使阀瓣与阀座的密封面密合而关闭,达到阻止介质逆流的目的。
2、阀体及阀瓣的密封面采用不锈钢堆焊。
3、本阀门的结构长度按GB12221-1989的规定,法兰连接尺寸按JB/T79-1994的规定。
