具体实施方式
以下结合说明书附图来进一步说明本发明。
如图所示以二楼为例，建筑楼房节水系统包括自来水管1、用水设施2、用水设施排水管3、中水进水管4、中水收集管7、中水排水管8、中水出水阀13、中水溢流管14、排污管15等，所述的中水收集管7安装在建筑楼房上，并在各楼层预置中水收集管7出入水口，中水排水管8、中水进水管4与中水收集管7出入水口分别接通，中水排水管8连通坐便器水箱11，中水排水管8上安装中水出水阀13，所述中水进水管4上设置第一止回阀5。当用户不用中水的时候可以关闭中水出水阀13，而第一止回阀5可以防止中水倒流进入用水设施2。
用水设施排水管3连接排水支管6，该排水支管6与排污管15接通，中水收集管7内的水位随着经中水进水管4、第一止回阀5流入的中水和经管路A21、管路B29流入的雨水以及经中水排水管8、巾水出水阀13排出的中水和经中水排水管A30、巾水排水管B31排出的中水的水量的变化而变化，也就是说中水收集管7内的水位是在不断变化的。
当中水收集管7内的水位高于中水进水管4时，用水设施2的排水不能经过中水进水管4、第一止回阀5排入中水收集管7内，这时排水经排水支管6流入排污管15内；当中水收集管7内的水位低于中水进水管4时，用水设施2的排水经中水进水管4、第一止回阀5流入中水收集管7内；当中水收集管7内的水位高于巾水排水管8时，浮球阀12自动关闭，中水收集管7内的中水代替自来水经中水排水管8、中水出水阀13流入抽水马桶水箱11内，起到节水的作用；当中水收集管7内的水位低于中水排水管8时，浮球阀12自动打开，自来水经自来水支管9、第二止回阀10、浮球阀12进入抽水马桶水箱11中，这时没有节水。
所述的中水溢流管14与中水收集管7、排污管15相通。此是为了中水收集管7的水 到达顶部时而不会溢出，也是缓解中水收集管7水压的措施。在中水收集管7底部连接设置中水排水管A30、中水排水管B31，该中水排水管A30、中水排水管B31与排污管15相通，并在中水排水管A30上设置第一阀门18，在中水排水管B31上设置第一压力阀17。当中水收集管7长时间装满水的时候，也可以通过开启第一阀门18的方式，将时间过长的中水收集管7内的中水排出，顺便清洗中水收集管7底部残留的杂质，此时应将第三阀门23关闭；当溢流管14堵塞，中水收集管7的水又没有被使用，但用水设施2却还是不断的给中水收集管7增水而形成高压时，以免对中水收集管7等管路或者相关的止回阀或阀门的破坏，所以设计了在中水排水管B 31上没置第一压力阀17，即压力过大可以自动开启第一压力阀17放水，从而保护相关管路与阀门部件等。
在自来水管1连接设置自来水支管9，该自来水支管9与坐便器11水箱接通，且在该自来水支管9上设置第二止回阀10、浮球阀12。不使用中水的家庭，又或者中水量供应不足时，可以实现此结构功能，即当关闭中水出水阀13或坐便器水箱11没有中水储备时，浮球阀12就会自动开启为坐便器11供水，体现人性化设计理念。在建筑房顶24设置集雨斜坡25，该集雨斜坡25与中水收集管7顶部接通，雨天时可以直接收集雨水作为中水使用，雨水相对中水也会相对清洁，同时也可以将中水管内的中水做简单中和，保证相对清洁，让该节水系统更加完善。
在多雨地区，为了能够更好的利用雨水，中水收集管7经管路A21还可连通设置雨水收集管27，并在管路A21上设置第三止回阀22，该第三止回阀22使雨水收集管27的水只能往中水收集管7流而不能倒流。此时，集雨斜坡25应该与雨水收集管27顶部先接通。在管路A21上设置第三阀门23，雨水收集管27底部连接设置雨水排水管A32、雨水排水管B33，该雨水排水管A32、雨水排水管B33与排污管15相通，并在雨水排水管A32上设置第二阀门20，在雨水排水管B33上设置第二压力阀19。当要清洗雨水收集管27时，开启第二阀门20可以放水清洗雨水收集管27。雨水收集管27顶部与中水收集管7顶部经管路B29接通，且在管路B29上设置第四止回阀28，当雨水收集管27的水过多时，可以通过第四止回阀28将水流入中水收集管7，当第四止回阀28或溢流管14堵塞，雨水又源源不断的补充入雨水收集管27而形成高压时，第二压力阀19就会开启如第一压力阀相同的功能，用于保护相关管路及其他设备设施。
另外所述中水收集管7的管径应该要大于中水进水管4的管径，雨水收集管27管径应该要大于中水收集管7的管径，中水收集管7或雨水收集管27与集雨斜坡25通过管路C26连通。雨水收集管27内的水也可用于绿化、洒水车、洗车、应急消防用水，在相应楼层安装阀门后，还可用于清洗楼道、楼梯等。当然为了能够更加卫生清洁，可以适当地在中水收集管内加入一些消毒除臭剂。
