Installation Instruction
 |
当壳体壁厚H＞3mm时建议开设螺纹孔类型进行安装，使用螺纹规格为M12*1.5； When the housing wall thickness H >3mm, it is recommended to open the threaded hole for installation, and the thread specification is M12*1.5 使用平垫圈时，头部不需倒角。 Chamfering is not required when using flat washer |
|
当壳体壁厚H≤3mm时，建议开设直通孔类型并且配合螺母进行安装，开孔直径为： ø12.2mm； When the housing wall thickness H≤3mm, it is recommended to open straight through holes and install them with nuts. The hole diameter is ø12.2mm 建议使用平垫圈，头部不需倒角。 Chamfering is not required when using flat washer |
螺纹式透气阀安装方式 Threaded installation for Screw Vents：
-
1)清洁安装表面和螺钉安装通风口的安装区域，以清除任何污染物;
Clean the installation surface and the installation area of the screw installation vent to remove any containinant.
-
2)理想的安装位置是在外壳壁上的平坦、垂直表面上。该位置将防止液体积聚；
The ideal installation position is on the flat and vertical surface of the housing wall. This location will prevent liquid accumulation
-
3)将螺纹正确对齐的螺丝配合通风口插入外壳，然后拧入外壳；
Insert the screw with correctly aligned thread into the housing with the vent, and then screw it into the housing
-
4)当壁厚合适时，建议使用倒角以优化O型环密封.
When the wall thickness is appropriate, it is recommended to use chamfer to optimize the O-ring seal
