气动O-类型球阀：多功能工业组件

气动O-型球阀是一个至关重要的工业阀，它利用气动执行器来调节球形盘的旋转，称为球。该阀旨在控制各种流体的流动，包括工业管道中的气体，液体，甚至一些浆液。

结构和组件

气动O-型球阀的基本结构相对简单而高效。它主要由球，阀座，阀杆和气动执行器组成。球有一个穿过其中心的孔，该孔处于圆的形状（O-类型），当球被气动执行器旋转时，该孔与管道的流动路径对齐或错过，从而控制流动。
阀座通常由诸如PTFE（Polytetrafluoroethelene）之类的材料制成，用于软密封应用或用于硬密封的金属，当阀门关闭时，可以对球紧密密封。阀杆将球连接到气动执行器，从而传递旋转力。
可以用压缩空气驱动的气动执行器，可以是双作用或单个表演。双 - 代理执行器使用气压打开和关闭阀门，而单个代理执行器将气压用于一个方向（打开或关闭）和弹簧进行返回动作。此设计功能在需要失败 - 安全操作的应用中特别有用。例如，在单个表演弹簧 - 返回执行器中，如果气压损失，弹簧会自动将阀门移至预定位置，即完全开放或完全闭合，具体取决于应用程序的安全要求。
