球阀是一种转角为90°的旋转类阀门,密封性能优良, (全径球阀)流量系数大流阻系数小,结构简单,使用寿命长,便于维修。
Q41F球阀有全通径和缩径两种结构形式。用于输送帖连、易结渣介质管道上的球阀应使用全通径的,方便定期的刮蜡吹扫器的通过。用于输送气体或物理性能近似于水的介质的管道上宜使用缩径球阀,因其重量比全径球阀轻30%左右,有利于减轻管道负荷,降低成本。球阀是一种转角为90°的旋转类阀门,密封性能优良, (全径球阀)流量系数大流阻系数小,结构简单,使用寿命长,便于维修。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。
