What is the usual valve mounting attitude?
The author: Time:2021/3/6

        闸阀是双闸板结构的,应该直立安装,即阀杆处于铅垂位置,手轮在上面。对单闸板结构的,可在任意角度上安装,但不允许倒装。对带有传动装置的闸阀,如齿轮、蜗轮、电动、气动、液动闸阀,按照产品说明书安装,一般阀杆铅垂安装为好。
       截止阀、节流阀可安装在设备或管道的任意位置,带传动装置的阀广]应该按照产品说明书规定安装。截止阀阀杆水平安装会使阀瓣与阀座不同轴线,有位移现象,密封面容易掉线,发生泄漏,因此,截止阀阀杆应该尽量铅重安装为好。节流阀需经常操作、调节流量,应安装在较宽敞的位置。
       升降式止回阀,只能水平安装在管道上,阀瓣的轴线呈铅垂状。弹簧立式升降式止回阀、旋启式止回阀可水平安裴在管道上,也可安装在介质自下向上流动的竖管上。旋启式摇.杆销轴安装时应该保持水平位置。球阀、蝶阀和隔膜阀可安装在设备和管道。
