侧装式偏心半球阀,PQ340F侧装式偏心半球阀是近年来在欧美广泛应用的阀门产品。它通过转动蜗轮(或电动)机构,带动偏心半球转动,从而实现阀门的启闭。流阻小,密封可靠,性能稳定。被广泛应用于市政污水处理、供水及其它流体控制系统。

1.水损为零。采用偏心结构,阀门开启后,流道完全畅通,水头损失为零。可节约大量能源。 
2.可靠的密封方式。软密封结构具有自密封性能,硬密封结构具有弹性补偿性能。 
3.耐磨损,使用寿命长。球阀在开启后,球冠偏置于阀体内,不被介质直接冲刷。 
4.自动清污功能。硬密封偏心半球阀的球冠边沿采用刀刃状,不但可以刮去阀座上的污垢,还可以切断杂物。 
5.启闭迅速。偏心曲轴旋转90度即可实现启闭,启闭时间短 
6.适合高流速。直通流道,坚固的偏心曲轴使之适用高流速且无振动。 
1.适用介质:清水.原水(含泥沙).污水.海水、蒸汽、煤气、天然气、油品等。 
2.适用温度:软密封偏心半球阀为-40℃-135℃;硬密封半求阀为常温至600℃左右 
3.适用压力:PN6-PN64。 
4.公称通经:DN50~DN1600
