关健词建筑节约用水超压出流热水循环方式管阀泄漏中水系统雨水回收利用

我国水资源总量居世界第六位,但按人均水资源量计量,人均占有量为 2500m3,仅为世界人均水量的 1/4,世界排名第 110 位,是个人均水资源严重匾乏的国家。当前,在全国 668 座城市中,有 400 多座城市缺水,年缺水量达 60 多亿 m3。长期以来,在“水资源取之不尽,用之不竭”的传统价值观念影响下,水资源被长期无偿利用,导致人们的节水意识低下,造成了巨大的水资源浪费和水资源非持续开发利用。水资源日益短缺,合理开发水资源、利用水资源、保护生态环境,维护人与自然的和谐,已经成为人类共同的使命。本文就建筑给排水设计中所能采取的节水措施,探讨如下。

3 减少管道和阀门泄漏浪费

管道、阀门的选材及安装质量等导致大量的水消失于无形。经常都能看到路边的给水管道在管子接缝处及法兰、阀门连接处滋滋的往外冒水。埋在地下的看不见的更不知道有多少。用户们反映浮球阀经常损坏、漏水,不论是用于水池、水箱的还是马桶上使用的,其质量的低劣直接导致大量水从溢流管流出。解决此问题需合理选用优质的管道和阀门,并在施工以及后期物业管理过程中严格管理。
