全压高速排气阀PQ42X全压高速排气阀Word文件下载.docx

1、管道在运转时出现停电、停泵管道及时出现负压力会引起管道振动或破裂。排、进气阀就迅速把空气吸入管内,防止管道振动或破裂。全压高速排气阀原理:当水进入管路时,塞头停在定位架下部,进行大量排气，当空气排完时,水进入阀门把球浮起,传动塞头到关闭,停止排气。管道在正常运转时自然会产生少量气体,这些气体会聚集到管内上部,到相当程度,阀内水位下降,浮球顺水下降气体从小孔排出,如出现停电、停泵,管道内水流空时随时会出现负压,浮球顺水下降,打开小孔带动大孔进行大量进气确保管道安全。其它阀系列价格供用户或设计院工程项目做预算管夹阀价格表口径手动电动DN504501350DN656901575DN801020337
