三、特点及优点

1、手动部分可采用钢板压制的手柄或不锈钢铸造的手柄。手柄设有限位结构,在阀门开启、关闭的位置设定限位,当阀门使用在关键装置上时,限位块上设有锁孔可锁定开   关位置避免误操作。手柄上有明显地开和关标识。

2、阀杆采用A182F(1Cr13)整体锻造并调制处理,硬度达到HB220~250。阀杆通过平键或花键或方契与手柄连接,通用性强,拆装方便。阀杆设有防吹出结构。

3、阀门的填料选用编结、柔性石墨密封圈或四氟烯密封圈,使得阀杆在一定的润滑情况下实现可靠的密封。

4、根据需要,球阀可设计成防静电结构,在球体与阀杆、阀杆与阀体之间设置导电弹簧,避免静电打火点燃易燃物质,确保系统安全。

5、密封副形式多样。根据不同工况可选用软密封、硬密封、防火阀座等结构;DN150以下为浮球形式,DN200以下为固定球形式。

6、球阀阀座处可设置辅助密封结构,在阀座和阀杆部位加装注脂阀,紧急情况下可暂时密封,并可根据需要加长阀杆以适宜埋地铺设得场所
