【正文】 mpty of pottype 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 zincplated steel tube generally, because zincplated steel tube exchange the corrosion, Use shortlived , use for and send domestic water can satisfied with water quality sanitary standard shorting, 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 zincplated steel tube , use widely the feed pipe of plastics. The plastics supply water In charge of pared 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 energyconservation of the province, merit of having long performance life etc.. Supply water and use plastics pipeline: Hard polyvinyl chloride( PVCU), high density polyethylene( HDPE), pay and unite polyethylene( PEX) , modify the polypropylene( PPR, PPC), gather butene( PB), aluminium mould and pound and in charge of and the steel is moulded and pound and is managed etc.. Choice of tubular product economic parative 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 mediumlevel ines 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。 Reserve solar water heater and cold hot water installation position of pipeline in advance only. The cold hot water pipeline of the solar water heater can be laid In the pipeline well。塑料給水 管與金屬管道相比，具有重量輕，耐壓強(qiáng)度好，輸送液體阻力小，耐化學(xué)腐蝕性能強(qiáng)，安裝方便， 省鋼節(jié)能，使用壽命長等 優(yōu)點(diǎn)。 （ 2）明裝在建筑物外墻陰角處。給水支管暗 設(shè)的方式有： （ 1） 暗設(shè)在磚墻里。 （ 3）排水支管敷設(shè) 住宅室內(nèi)排水橫管宜設(shè)在本層套內(nèi)，這樣排水橫管滲透時可避免污水等污染物進(jìn)入鄰戶，管道維修時也不會影響到鄰 戶的正常生活。暗埋管道安裝時，施工質(zhì)量一定要嚴(yán)格把關(guān)， 經(jīng)驗(yàn)收合格后方可施工衛(wèi)生間地面，以免給日后使用中留下隱患。住戶給水支管經(jīng)水表計(jì)量后進(jìn)入廚房、衛(wèi)生間。 （四）家用熱水器的設(shè)置問題 住宅設(shè)計(jì)時應(yīng)預(yù)留安裝熱水供應(yīng)設(shè)施的條件，或設(shè)置熱水供應(yīng)設(shè)施。 （五）空調(diào)冷凝水排放問題 近 幾年，空調(diào)逐漸進(jìn)入千家萬戶，空調(diào)冷凝水無組織排放污染建筑物外墻，已是影響生活區(qū)美觀的一個重要問題。所以在建筑給排水設(shè)計(jì)時需要先征求開發(fā)商的意見，是否統(tǒng) 一設(shè)計(jì)，統(tǒng)一施工太陽能熱水器；或只預(yù)留出太陽能熱水器及冷熱水管道的安裝位置。水表出戶布置的方式選擇，須結(jié)合住宅廚房、衛(wèi)生間平面布置特點(diǎn)和開發(fā) 商的具體要求，對以上幾種可行性方案進(jìn)行經(jīng)濟(jì)技術(shù)比較后確定。 采用磁卡式水表 用戶預(yù)先購買自來水公司的電子卡，然后把它插入水表的存貯器內(nèi)，用水時卡上金額被自動扣除，這種方式用戶需預(yù)付 水費(fèi)，水表價格較高。衛(wèi)生間樓板面下沉 350mm，衛(wèi)生器具排水橫管暗埋在下沉空間里。這樣既可避免暗埋管道的管接頭 滲 透問題。本人認(rèn)為：在中高檔的商品房建筑方案設(shè)計(jì)時應(yīng)考慮衛(wèi)生間管道井的設(shè)置，這樣 即提高衛(wèi)生間的使用質(zhì)量， 又可解決硬聚氯乙烯排水管水流噪聲大的問題，提高居室的環(huán)境質(zhì)量水平；對于衛(wèi)生間面積較小的經(jīng)濟(jì)適用房和 解困房， 在南方較暖和地區(qū)給排水立管可考慮敷設(shè)在外墻，以增大衛(wèi)生間的使用空間；管道明裝在室內(nèi)時，應(yīng)不 影響廚房、衛(wèi)生間各衛(wèi)生設(shè)備功能的使用。 （二） 管道敷設(shè)問題 給排水立管的敷設(shè)一般有以下幾種方式 （ 1）明裝在廚房、衛(wèi)生間的墻角處。 （一） 給水管材選用問題 傳統(tǒng)的給水管材一般采用鍍鋅鋼管，由于鍍鋅鋼管易銹蝕，使用壽命短，用于輸送生活用水不能滿足水質(zhì)衛(wèi)生標(biāo)準(zhǔn)等 缺點(diǎn)，建設(shè)部正大力推廣塑料給水管的應(yīng)用。 Estate management perfect medium tohigh grade modity apartment of housing district, can adopt magic stripe card water gauge( Company have this kind district of business can design in running water) Or concentrate on setting up it among the water gauges( case)。 Mediumtohigh grade modity apartment available aluminium Mould and pound 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 abovementioned tubular product in charge of except hard polyvinyl chloride and aluminium plastics pound and in charge of( PEALPE), 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 ****學(xué)院本科畢業(yè)設(shè)計(jì) 原文 （ 1)Will install it in the corner place of the kitchen, bathroom tomorrow. Adopting this kind of way of laying more in the
