一种便于安装的浮动球阀

Abstract

本实用新型提供一种便于安装的浮动球阀，涉及阀门技术领域，包括第一阀体，所述第一阀体的顶部设置有固定管，所述固定管的内部设置有卡扣组件，所述卡扣组件远离固定管的一端设置有第一密封圈，所述第一密封圈的顶部设置有第二密封圈。本实用新型中，一方面通过设置第一密封圈和第二密封圈，且二者相配合，外周还设置有涂层，即使其中一个密封圈出现一定程度的磨损，另一个密封圈仍能起到密封作用，提高了密封的可靠性，配合卡扣组件，便于对磨损的密封圈进行更换；另一方面通过在叶轮的外周设置刮板，在介质流动时，会带动叶轮绕固定轴转动，叶轮上的刮板在转动过程中会不断刮除球体内壁上的杂质，保证了阀门的稳定性。
