1.室內(nèi)消火栓超過10個且室外消防用水量大于15L/s時,，其消防給水管道應連成環(huán)狀,，且少應有2條進水管與室外管網(wǎng)或消防水泵連接。當其中一條進水管發(fā)生事故時,，其余的進水管應仍能供應全部消防用水量,。
When there are more than 10 indoor fire hydrants and the outdoor fire water consumption is greater than 15L/s, the fire water supply pipeline should be connected in a circular shape, and at least 2 inlet pipes should be connected to the outdoor pipeline network or fire water pump. When one of the inlet pipes experiences an accident, the remaining inlet pipes should still be able to supply all firefighting water.
2.高層建筑應設置獨立的消防給水系統(tǒng)。室內(nèi)消防豎管應連成環(huán)狀,，每根消防豎管的直徑應按通過的流量經(jīng)計算確定，但不應小于DN100,。
2. High rise buildings should be equipped with independent fire water supply systems. Indoor fire protection vertical pipes should be connected in a circular shape, and the diameter of each fire protection vertical pipe should be determined by calculation based on the flow rate passed through, but should not be less than DN100.
3.60m以下的單元式住宅建筑和60m以下,、每層不超過8戶、建筑面積不超過650㎡的塔式住宅建筑,，當設兩根消防豎管有困難時,，可設一根豎管，但必須采用雙閥雙出口型消火栓,。
For unit residential buildings below 3.60m and tower residential buildings below 60m, with no more than 8 households per floor and a building area of no more than 650 square meters, when it is difficult to install two fire vertical pipes, one vertical pipe can be installed, but double valve and double outlet fire hydrants must be used.
4.室內(nèi)消火栓給水管網(wǎng)應與自動噴水滅火系統(tǒng)的管網(wǎng)分開設置,；當合用消防泵時，供水管路應在報警閥前分開設置,。
4. The indoor fire hydrant water supply pipe network should be separated from the pipeline network of the automatic sprinkler fire extinguishing system; When using a shared fire pump, the water supply pipeline should be separated before the alarm valve.
5.高層建筑,，設置室內(nèi)消火栓且層數(shù)超過4層的廠房（倉庫），設置室內(nèi)消火栓且層數(shù)超過5層的公共建筑,，其室內(nèi)消火栓給水系統(tǒng)和自動噴水滅火系統(tǒng)應設置消防水泵接合器,。
5. For high-rise buildings, factories (warehouses) with indoor fire hydrants and more than 4 floors, and public buildings with indoor fire hydrants and more than 5 floors, their indoor fire hydrant water supply system and automatic sprinkler fire extinguishing system should be equipped with fire pump adapters.
消防水泵接合器應設置在室外便于消防車使用的地點，與室外消火栓或消防水池取水口的距離宜為15~40m,。水泵接合器宜采用地上式,，當采用地下式水泵接合器時，應有明顯標志,。
The fire pump adapter should be located outdoors in a location convenient for fire trucks to use, and the distance from the outdoor fire hydrant or fire water tank inlet should be 15-40m. The water pump adapter should be above ground, and when using an underground water pump adapter, there should be clear markings.
消防水泵接合器的數(shù)量應按室內(nèi)消防用水量計算確定,。每個消防水泵接合器的流量宜按10~15L/s計算。消防給水為豎向分區(qū)供水時，在消防車供水壓力范圍內(nèi)的分區(qū),，應分別設置水泵接合器,。
The number of fire pump couplings should be determined based on the indoor fire water consumption calculation. The flow rate of each fire pump adapter should be calculated at 10-15L/s. When the fire water supply is in vertical zones, water pump couplings should be installed in the zones within the pressure range of the fire truck's water supply.
6.室內(nèi)消防給水管道應采用閥門分成若干獨立段。對于單層廠房（倉庫）和公共建筑,，檢修停止使用的消火栓不應超過5個,。對于多層民用建筑和其他廠房（倉庫），室內(nèi)消防給水管道上閥門的布置應保證檢修管道時關(guān)閉的豎管不超過1根,，但設置的豎管超過3根時,，可關(guān)閉2根；對于高層民用建筑,，當豎管超過4根時,，可關(guān)閉不相鄰的兩根。
6. Indoor fire water supply pipelines should be divided into several independent sections using valves. For single story factory buildings (warehouses) and public buildings, the number of fire hydrants that need to be stopped for maintenance should not exceed 5. For multi story civil buildings and other factories (warehouses), the arrangement of valves on indoor fire water supply pipelines should ensure that no more than one vertical pipe is closed during maintenance, but when more than three vertical pipes are set, two can be closed; For high-rise civil buildings, when there are more than 4 vertical pipes, the two non adjacent pipes can be closed.
閥門應保持常開,，并應有明顯的啟閉標志或信號,。
Valves should remain normally open and have clear opening and closing signs or signals.
7.消防用水與其他用水合用的室內(nèi)管道，當其他用水達到小時流量時,，應仍能保證供應全部消防用水,。
7. Indoor pipelines for fire water and other hydration purposes should still be able to supply all fire water when the maximum hourly flow rate of other water is reached.
8.允許直接吸水的市政給水管網(wǎng)，當生產(chǎn),、生活用水量達到且仍能滿足室內(nèi)外消防用水量時,，消防泵宜直接從市政給水管網(wǎng)吸水。
8. For municipal water supply networks that allow direct water absorption, when the production and domestic water consumption reaches its maximum and can still meet the indoor and outdoor fire water consumption, the fire pump should directly absorb water from the municipal water supply network.
9.嚴寒和寒冷地區(qū)非采暖的廠房（倉庫）及其他建筑的室內(nèi)消火栓系統(tǒng),，可采用干式系統(tǒng),，但在進水管上應設置快速啟閉裝置，管道處應設置自動排氣閥,。
9. Indoor fire hydrant systems for non heating factories (warehouses) and other buildings in extremely cold and cold areas can use dry systems, but quick opening and closing devices should be installed on the inlet pipes, and automatic exhaust valves should be installed at the highest point of the pipes.
