questions designed

Summary : This text give and drain off water on multilevel residential housing design supply water the exertion of the tubular product , Way of laying of pipeline, water gauge produce family set up, establishment and air conditioner condensation water of pot-type boiler discharge issue goes on the discussion , And put forward some concrete views.

Keyword: Skyscraper, supply water the tubular product , the pipeline is laid, The water gauge, the solar water heater

The skyscraper is simple with its auxiliary facility, the fabrication cost is low, the characteristic such as being convenient of estate management, Receive the welcomes of the real estate developer and vast resident of small and medium-sized cities very much. How project planning and design of inhabited region, scientific and technological industry of comfortable house, lead the request according to 2000, Improve the design level of the house, build out a comfortable living space for each household, It is each designers duty. As the heart of the house --The kitchen, bathroom, is that the function is complicated, hygiene, safe and comfortable degree are expected much, It is miscellaneous to build, the space expecting much in technology. So, the designer must consider synthetically with the idea and method of global design that the kitchen, bathroom give installation of the drainage pipeline and equipment,etc. . Give and drain off water on skyscraper design supply water exertion, to lay pipeline of tubular product, water gauge produce family set up, establishment and empty of pot-type boiler now Transfer condensation water discharge issue discuss together with colleagues.

( 1)supply water tubular product select problem for use Traditional watersupply tubular product adopt zinc-plated steel tube generally, because zinc-plated steel tube exchange the corrosion, Use short-lived , use for and send domestic water can satisfied with water quality sanitary standard shortcoming, Ministry of Construction is popularizing the application of the feed pipe of plastics energetically . A lot of districts and cities have already expressed regulations: Forbid designing and using the zinc-plated steel tube , use widely the feed pipe of plastics. The plastics supply water In charge of compared with metal pipeline, light, it is fine to able to bear the intensity of keeping, Send obstruction little liquid , able to bear chemistry better to corrode performance, it is convenient to install, The steel energy-conservation of the province, merit of having long performance life etc.. Supply water and use plastics pipeline: Hard polyvinyl

chloride( PVC-U), high density polyethylene( HDPE), pay and unite polyethylene( PEX) , modify the polypropylene( PP-R, PP-C), gather butene( PB), aluminium mould and compound and in charge of and the steel is moulded and compound and is managed etc.. Choice of tubular product economic comparative course of technology, technology should from pressure, temperature, environment for use, install method,etc. go on and consider, Combine owners at the same time request and the house of grade,carry on and fix after being consider synthetically technology not economic. The above plastics supply water tubular product can supply water tubular product as house life. The economic and functional house conciliating Strand room in the face of the masses of with low- and medium-level incomes resident, can select for use hygiene grades of hard polyvinyl chloride in charge of as feed pipe mainly, In order to reduce the fabrication cost; Medium-to-high grade commodity apartment available aluminium Mould and compound and in charge of or other plastics supply water the tubular product as the feed pipe. House mix hot water temperature that water order exceed 600 C, so above-mentioned tubular product in charge of except hard polyvinyl chloride and aluminium plastics compound and in charge of( PE-AL-PE), Mostly the tubular product can be regarded as the hot water pipeline of the house.

( 2) pipeline lay problem 1. give and drain off water it set up there arent one that in charge of
