气动快开排泥阀，是一种由液压源或气动源作执行机构的角型截断类阀门。通常成排安装在沉淀池底部外侧壁，用以排除池底沉淀的泥砂和污物。该阀由泥龙强化橡胶隔膜将阀门分为两个腔室，接通液压或气动源，采用电动或手动二位四通换向阀控制，实现快速排泥。该阀将隔膜代替活塞，无运动摩檫，更适用于泥浆等颗粒介质，大大提高了阀门的使用寿命。

流体阻力小，其阻力系数与同长度的管段相等。
2． 结构简单、体积小、重量轻。
3． 紧密可靠，目前球阀的密封面材料广泛使用塑料、密封性好，在真空系统中也已广泛使用。
4． 操作方便，开闭迅速，从全开到全关只要旋转90°，便于远距离的控制。
5． 维修方便，球阀结构简单，密封圈一般都是活动的，拆卸更换都比较方便。
6． 在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀。
7． 适用范围广，通径从小到几毫米，大到几米，从高真空至高压力都可应用。
三片式锻钢球阀按其通道位置可分为直通式，三通式和直角式。后两种球阀用于分配介质与改变介质的流向。三片式球阀安装与维护应注意以
