巧接支管装排水立管时,不允许用正三通,只能用斜三通或顺水三通,以便排除空气,预防污物堵塞管道。装采暖支管三通时,应用羊角三通,可防止产生涡流现象,平衡系统热量。压缩空气管道接支管时,则为开口扩开的三通,便于组织气流,保证供气的连续性。 Ingenuity pipe fittings installed drainage riser, is not allowed to use the three links, only with oblique links or water three links, in order to rule out the air, to prevent dirt blocking the pipeline. Install heating branch tee, the application of the horn three links, to prevent eddy current phenomenon, the balance of system heat. When the compressed air pipe is connected with the branch pipe, it is the three-way expansion opening, which is convenient for the tissue air flow and ensures the continuity of the air supply.
