Description:

复合式清水排气阀 CARX

概况:
本产品用于管路上的最高点或有闭气的地方,靠排除管内的气体来疏通管道,达到正常工作。如不装排气阀,管道随时出现起阻,是管道出水容量达不到设计要求,其次:其次:管道在运转时出现停电、停泵管道及时出现负压会引起管道振动或破裂,排(吸)气阀就迅速把空气吸入管内,防止管道振动或破裂。
作用原理:
当水进入管内时,浮球停在球桶下部进行大量排气,当气排完时,水进入阀内通过球桶把球浮起到关闭,停止排气,管道在正常运转时自然会产生少量气体,这时气体会集中到管内上部到相当程度,阀内水下降,浮球顺水下降气体从小孔排出。如出现停电停泵,管内水流空时,随时出现负压,浮球顺水下降,打开小孔带动大孔进行大量补气确保管道安全。
注:排气阀在使用过程中压力不低于0.03Mpa,如低于0.03Mpa排气阀容易漏水。必须配一只阀门作为检修用。
技术参数:
1.       工作压力:1.0Mpa
2.       介质:清水
3.       使用温度:常温
4.       阀体:HT200
5.       浮球与塞头:不锈钢
6.       密封材料:丁晴橡胶
