美标固定式气动球阀一般为法兰连接,且球体是固定的,采用上下阀杆固定阀芯(轴支式)和可动密封座设计,关闭时,在介质压力的作用下,球体不会产生位移,耕作更稳定,常用于高压和大口径的各种管路上。气动固定式球阀通常与球体连接在一起的上下轴上,装有滚动轴承或滑动轴承,以减少启闭时轴颈的摩擦力,减小操作力矩,在各行业得到广泛的应用。
固定式气动球阀大多数采用法兰连接,适用于长输管线和一般工业管线,其强度、安全性、耐恶劣环境性等在设计时进行了特殊考虑,用于截断或接通管路中的介质,选用不同的材质,可分别适用于水、蒸汽、油品、液化气、天然气、煤气、硝酸、醋酸、氧化性介质、尿素等多种介质,广泛应用于石油化工电力水利等行业。
