【正文】 每個(gè)防火分區(qū)的配水分干管設(shè)水流指示器，豎直安裝在水平管道上側(cè)；信號(hào)閥安裝在水流指示器前的管道上，與水流指示器之間的距離不小于 300mm。 ? 噴頭安裝在傾斜的屋面板、吊頂下面時(shí)，計(jì)算噴頭間距應(yīng)按水平投影考慮。 當(dāng)閥瓣壓在瓣槽上時(shí)，小孔被閥瓣堵住，沒(méi)有水流入空腔，因此水力警鈴不動(dòng)作。 ○ 7 每座或每個(gè)防火隔間的占地面積超過(guò) 600m2的香煙、火柴庫(kù)房。消防水池的有效容積為 ，消防水箱的有效容積為 42m3。因?yàn)橄鹚ㄋ诘撵o水壓力不大于 ，所以消火栓給水系統(tǒng)不用分區(qū)。水泵接合器是消防車往室內(nèi)管網(wǎng)供水的接口，當(dāng)室內(nèi)消防水泵發(fā)生故障或室內(nèi)消防用水量不足時(shí)，消防車隊(duì)即從室外第二章 設(shè)計(jì)說(shuō)明書(shū) 17 消火栓、消防水池或天然水源取水，通過(guò)水泵接合器將水送至室內(nèi)管網(wǎng)，保證室內(nèi)火場(chǎng)用水。 消防管網(wǎng)上的閥門應(yīng)經(jīng)常處于開(kāi)啟狀態(tài)，為防止檢修管道或者消防設(shè)備后忘記打開(kāi)或誤關(guān)閉，閥門應(yīng)有明顯的啟閉標(biāo)志、信號(hào)，或在閥門開(kāi)啟后進(jìn)行鉛封。由于低區(qū)的用水器具較少，故不對(duì)其集中供應(yīng)熱水。 當(dāng)采用塑料熱水管或塑料和金屬?gòu)?fù)合熱水管材時(shí)應(yīng)符合下列要求： ① 管道的工作壓力應(yīng)按相應(yīng)溫度下的許用工作壓力選擇； ② 設(shè)備機(jī)房?jī)?nèi)的管道不應(yīng)采用塑料熱水管。該方式多用于設(shè)有全日供應(yīng)熱水的建筑和設(shè)有定時(shí)供應(yīng)熱水的高層建筑中；干管循環(huán)熱水供水方式是指僅保持熱水干管內(nèi)的熱水循環(huán)，多用于采用定時(shí)供應(yīng)熱水的建筑中。如：自動(dòng)溫度調(diào)節(jié)器、疏水器、減壓閥、安全閥、膨脹罐、管道補(bǔ)償器、閘閥、水嘴等。 熱水給水系統(tǒng)的設(shè)計(jì) 熱水給水系統(tǒng)的分類和組成 建筑內(nèi)的熱水供應(yīng)系統(tǒng)按熱水供水范圍的大小，可分為集中熱水供應(yīng)系統(tǒng)和局部熱水供應(yīng)系統(tǒng)。三通，立 管與出戶管或排水橫管連接時(shí)必須用 2個(gè) 45176。 ③架空管道不得敷設(shè)在對(duì)生產(chǎn)工藝或衛(wèi)生有特殊要求的生產(chǎn)廠房?jī)?nèi)，以及食品和貴重商品倉(cāng)庫(kù)、通風(fēng)小室、變電室間和電梯房?jī)?nèi)。 ①無(wú)通氣管的單立管排水系統(tǒng) ②有伸頂通氣的普通單立管排水系統(tǒng) ③特制配件的單立管排水系統(tǒng) ?雙立管排水系統(tǒng)：由 1 根排水立管和 1 根通氣立管組成的系統(tǒng)。高區(qū)水泵采用 2 臺(tái) IS8050250 型離心泵，恒速天津城市建設(shè)學(xué)院畢業(yè)設(shè)計(jì)說(shuō)明書(shū) 6 運(yùn)行。 ? 給水管道的布置與敷設(shè) ①室內(nèi)給水管網(wǎng)宜采用枝狀布置，單向供水。 ?串聯(lián)式分區(qū)給水方式優(yōu)點(diǎn)是無(wú)需設(shè)置高壓水泵和高壓管線，水泵可保持在高效區(qū)工作，能耗較少；管道布置簡(jiǎn)單，較省管材。 ?設(shè)水泵的給水方式：適用于室外給水管網(wǎng)的水壓經(jīng)常不足時(shí)采用。 13th~20th floor is high zone which is uplink and down watersupply mode supplied by water pumps and roof tanks. Drainage system: the drainage system of 4th20th floor is separate mode for feces wastewater and other wastewater, including three standpipes and stack vent. The drainage system of 1st3rd floor is bined system which is drained to the outside drainage system. Hot water system: This building uses a centralized hotwater supply system which consistent with water supply systems. 4th12th floor is central zone and 13th20th floor is high zone. As the points of distribution in 1st3rd floor are less, there is not a hot water supply system there. Hotwater system in each zone is independent, using volume mode water heaters and concentrated layer equipment installed in the basement of the building, in which the main pipe cycle use pump to circling. Hydrant water supply systems: The building height is over 50 meters which is the first class of highrise buildings, in which indoor hydrant system is separated from domestic water supply system. The hydrant water supply system hasn’t been zoned. The entire system is a circle mode with 3 sets of water pump adapters. Sprinkler system: Since the risk level of the building is first class dangerous level, the sprinkler system is wet auto sprinkler system which is supplied from the pumps in basement and roof water tanks. There are 3 sets of alarm valve group and 2 sets of pump adapters. Behind the alarm valve group, there is a water flow indicator at the initial section of water supply submain pipe.
