P4X-6/10 composite exhaust valve
Product Name:
P4X-6/10 composite exhaust valve
Description:

复合式排气阀 P4X-6/10

一、             用途
用于水泵出口及给水、排水管线中,具有自动排气与自动补气的功能,提高输水管路的排送效率,降低排送成本。一旦管道内产生负压,迅速导入外界空气,保护管线免受压破坏;并可迅速排出管道中的空气。
二、             特点
1.     密封可靠,特殊密封设计;
2.     自动排气与自动补气,无须人去操作;
3.     具有三种功能:(1)排出管道中的大量空气;(2)系统运行中的小量排气;(3)高速导入外界空气;
4.     经久耐用。小浮球按固定轨迹运动,不会碰撞壳体;
5.     关闭力大,较其它排气阀增加了配重—加大了关闭力;
6.     较其它种类的排气阀的高度尺寸小,(其他排气阀为阀盖中央排气);
7.     不会有压力水冲刷浮球,引起浮球的误动关闭。
三、             技术参数
1.     公称压力:1.0Mpa;
2.     适用介质:清水、污水、原水;
3.     介质温度:0-80℃
