【摘要】：减小建筑户内配水管道内水的停留时间,是降低或消除建筑户内配水管段对供水水质影响至关重要的措施之一。针对串连、链状、环状户内配管方式,通过模拟系统实测、分析,提出了环状配管阻力损失的理论计算方法;实测了相同工况下3种配管方式的阻力损失值;对比了3种配管方式洁具出流水中余氯、溶解氧的变化规律及配管内水流更新一次的时间。测试结果表明环状配管阻力损失最小,串连次之,链状阻力损失最大;环状、链状配管洁具出流余氯和溶解氧均比串连高;配管内水质全部更新一次所需时间环状最短,链状最长。从节能、节水、保障水质的角度考虑,户内环状配管为最优,链状配管适用于洁具少且布置紧凑的卫生间。
[Abstract]:It is one of the most important measures to reduce or eliminate the influence on water quality of water distribution pipes in building households by reducing the residence time of water distribution pipes. The theoretical calculation method of resistance loss of annular pipe is put forward, the value of resistance loss of three kinds of pipe matching modes under the same working condition is measured, and the residual chlorine of income in the three kinds of pipe fittings is compared. The change of dissolved oxygen and the time of renewal of flow in pipe. The test results show that the resistance loss of annular pipe is the least, the chain resistance is the largest, the loss of chain resistance is the largest, and the residual chlorine and dissolved oxygen in the ring and chain fittings are higher than those in the series. From the point of view of energy saving, water saving and ensuring water quality, the indoor annular pipe is the best, and the chain pipe is suitable for the bathroom with less sanitary utensils and compact arrangement.
