沟槽参数: |
|
|
|
|
|
|
|
|
|
1,允许的管道椭圆度不应超过1%。 |
2,最大与最小的管道直径之间过大的差距将导致接头安装的困难。 |
3,管端的垂直度允许的最大公差:DN15-90(1/2~3-1/2)为0.76mm(0.03"),DN100-150(4~6")为1.1mm(0.045") , |
DN200(8"及以上)为1.5mm(0.06")。 |
4,管端的外表面不得有焊缝或杂物,并与管道外表面齐平。管端的内表面应清洁,无油污,并清除氧化皮等,以免损坏滚槽压轮。 |
5,尺寸A:为密封面长度,是密封圈的密封工作区域,这个区域不得有凹陷,突起和压轮的压痕等,以确保密 |
封圈无泄漏,安装前必须清除所有的油,脂及污垢等。 |
6,尺寸B:为沟槽宽度,与密封面长度,接头键的宽度相配合,实现柔性接头的挠性。注意沟槽底部的圆角。 |
7,尺寸C:为沟槽底部直径,非常关键,必须与管道外径同心,沟槽深度在整个圆周上应均匀一致。 |
8,尺寸D:标准沟槽深度,仅是参考值,管端外径的变化将影响该尺寸,沟槽深度需适时调整,确保尺寸C处 |
于公差范围之内。注意:沟槽必须满足C尺寸的要求。 |
9,允许最小壁厚T: |
