1、比例式减压阀在高层建筑消防中的应用 摘要摘要：由于比例式减压阀的应用,简化了管路系统,减少了设备和控制系统,增加了建筑 使用面积,节省了投资， 具有良好的经济和社会效益。 采用减压阀分区有以下优点:采用减压 阀分区的系统、设备、管线都较简单,系统的维护管理也相对简便。减压阀阀前的压力波动 对阀后压力的影响较小,即减压阀有一定的稳定系统压力的作用,这对保持系统工作的稳定 性是有利的。采用减压阀分区,减少了水泵数量、管材用量,并省去了中间层的减压水箱,可 大大节约投资。 为使高层建筑减压阀供水系统真正能起到遇警显效的作用， 论文就消防给水 系统中比例式减压阀的原理、 设计以及比例式减压阀在安装中应

2、注意的几个问题进行了阐述。 关键词关键词:比例式减压阀；高层建筑；消火栓；供水方式。 Abstract: Because of the application of the relief pressure valve of proportion expression , have simplified the pipeline system , has reduced the equipment and control system, increase the use area of the building, save investment , have good economic and

3、social benefits. Adopt the dividing area of the relief pressure valve to have the following advantage : It is relatively simple to adopt system ,equipment , pipeline in the dividing area of the relief pressure valve, systematic maintenance management is relatively simple and convenient too. The fluc

4、tuation of the pressure had a little effect on the pressure after the valve in front of the relief pressure valve valve, namely the relief pressure valve had function of certain stable system pressure, this is favorable to stability which keeps system work. Adopt the dividing area of the relief pressure valve, reduce the quantity of the water pump , pipe consumption , save the depression water tank in the intermediate level , can practise thrift and make the investment greatly .In order for fir
