一般说来,屋面落水系统的管道有不锈钢管、铸铁管、镀或涂塑钢管以及高密度聚乙烯管,那么我们该如何选择落水系统的管道,保证安全,防止出现天沟溢水时间的发生,选择落水管道系统的标准。

  对于屋面雨水落水系统管材的选用标准,需根据建筑物的自身情况,综合考虑落水系统的工作压力、降噪要求、防火要求,以及安装简单的方便性,成本是否收到影响等因素,来进行合理的选择,除了这些基本的标准外,还有一些其他标准也是不容忽视的。
  
  落水系统管材的承压管、管配件和接口,其额定压力都不能小于建筑物的静水压,同时需要能承受一定的真空负压。但是优质的落水系统的排出管可以不需要进行耐负压的要求,这些关键的技术参数都需要供应商来进行提供。需要注意的是,在施工的时候,一定要分清楚管件是在那个位置和工段的,以免混淆。
In general, the pipes of the roof fall system include stainless steel pipes, cast iron pipes, Plated or coated steel pipes, and high-density polyethylene pipes. Then how do we choose the pipes of the fall system to ensure safety and prevent the occurrence of trench overflow time? Select the criteria for the underwater pipeline system.
Underwater system
For the criteria for the selection of pipes for roof rainwater falling systems, according to the building's own conditions, the working pressure, noise reduction requirements, fire protection requirements, simple convenience of installation, and whether the cost has been affected should be considered in a comprehensive manner. In addition to these basic criteria, there are other criteria that can not be ignored.
The pressure pipe, pipe fittings and interface of the pipe in the water system must not be less than the static pressure of the building, and at the same time it must be able to withstand a certain vacuum negative pressure. However, the discharge pipe of the high quality drowning system can not be required to withstand negative pressure. These key technical parameters need to be provided by the supplier. It should be noted that during construction, it must be clear that the pipe is in that position and the work section, so as not to confuse.
