在高层建筑给水设计中,采用分区供水系统是解决底部卫生器具静压过高的有效措施。但是,有些高层建筑因受其高度、面积及功能要求所限,不宜设置中间水箱进行分区供水时,尽管可以采取装设孔板、节流塞等措施,来增大阻力,达到减少流量的目的。但是,过高的静压无法减小。因此,卫生洁具泄水,使用不便,维修频繁等诸多弊病依然存在。为使设计省能在高层给水设计中,比较合理的选择经济、可靠的供水方案。中国建筑东北设计院和沈阳市五金公司,对用于高层建筑中可以减静压的减压阀进行了研制。一年多来,在“室内给水排水 In the water supply design of high-rise buildings, the use of a district water supply system is an effective measure to solve the high static pressure at the bottom of the sanitary appliances. However, some high-rise buildings are limited by their height, area, and functional requirements. It is not advisable to install intermediate tanks for partitioned water supply. Although measures such as orifice plates and throttling plugs can be adopted to increase resistance, the purpose of reducing the flow rate . However, excessive static pressure cannot be reduced. Therefore, there are still many drawbacks such as the leakage of sanitary ware, inconvenience in use, and frequent maintenance. In order to make design energy efficient in high-level water supply design, it is more reasonable to choose economic and reliable water supply solutions. China Northeast Building Design Institute and Shenyang Hardware Co., Ltd. have developed pressure reducing valves that can be used to reduce static pressure in high-rise buildings. For more than a year, "indoor water supply and drainage
