【 Weak current College 】 indoor water section III indoor water supply piping layout and wiring

First, the indoor water supply pipe pipeline layout 1. introducing-pipe layout
Building water service pipe from the water balance and water supply reliability considerations, to the maximum from building water consumption and do not allow the introduction of broken water Department. When building a comparative health appliances layout should be evenly in the introduction, in the middle of the building to reduce the pipe network to the most negative point of water, reduce the length of pipe head loss. The introduction of a pipe General settings, when the building is not allowed to stop water or indoor hydrant total in more than 10, you need to set two and should be made by the different urban ring network; if not introduced side may also be introduced with the side, but both into the pipe shall be not less than the distance between 10m, contacts between set valve.
Living water service pipe and sewage discharge pipe pipe of horizontal distance shall be not less than 1.0m.
Introducing tube through the load-bearing walls or Foundation, to set aside hole tube top upper reserved clearance shall not be less than the amount of settlement buildings, generally not less than 0.15m, and waterproof technology.
2. arrangement of indoor water supply piping
Indoor water supply piping layout and buildings, buildings, structures, and health equipment and production equipment layout and the water-supply mode, and should make full use of outdoor water supply network pressure. Piping arrangement should strive to achieve the shortest possible length of straight towards, and walls, beams and columns of the parallel laying, both in appearance and to consider the construction maintenance convenience.
Water and sewer water should be as close as possible to the largest equipment place or does not allow continuous supply of water to ensure a reliable supply of water, and reduce the flow of pipeline so that the transfer of large diameter pipe length min.
Indoor water pipes do not allow laying in drains, flue and air duct, is not allowed to pass through the toilet tank, window and wall cabinet, should be avoided as far as possible through the buildings of the settlement joint. 　　If you must go through when to take the appropriate measures. Second, indoor water system pipe laying indoor water supply pipe laying, construction on the health and beauty area requirements, divided into Ming installed and concealed two categories. (1) that installs
Pipe Interior along walls, beams, columns, ceiling and floor laying beside exposure. Ming installed pipe low cost, construction and installation, maintenance, repairs are more convenient. The disadvantage is that due to the pipe surface area of ash, produce condensing effects of environmental health, and Ming installed hinder housing. General civil buildings and most of the workshop are packed out.
(2) concealed
Pipeline laying in the basement ceiling or ceiling, or tube, pipe and tube ditch hidden installation. Concealed duct, the health conditions for the good, the room is beautiful. Standard high buildings, hotels, etc. are made of dark Pack; in industrial enterprises, some of the production process, such as precision instrument or electronic components clean and dust-free workplace requirements for indoor, also to adoption.　　Concealed disadvantage is cost, construction and maintenance are inconvenience. In addition to the separate laying of water pipeline, along with other pipe erection, considering security, construction and maintenance requirements, when parallel or crossover settings, on the pipeline between location, distances and fixed method should be called by the pipeline comprehensive integrated treatment.
