在目前來說，高位消防水箱的主要作用是提高臨時高壓給水系統的可能性，并且可以有效地臨時給水系統的可靠性能和系統化性能，提供系統標準工作性能的標準化程度和火災期消防系統所需要的水壓；從而可以有效火災發生后所需要的初期消防用水量。
At the early stage of the degree of standardization and fire in the current international, high fire water tank's main role is to improve the possibility of temporary high pressure water supply system, and can effectively ensure the temporary water supply system reliability and system performance, providing standard system working performance of fire protection systems require pressure; which can effectively ensure the fire occurred after the initial fire with water.
根據《建筑設計消防規范》的規定，消防水箱可以儲存10分鐘的儲水量，當消防用水量小于低于25毫升的時候，經計算消防水箱所需消防儲水量大于12m3時，仍可以采用12m3的水箱。
According to the provisions of the "code of fire protection design of buildings", fire water tank can store 10 minutes of water storage, when the fire with water content less than 25 ml, through the calculation of fire water tank for fire water storage than 12m3, still can use 12m3 tank.
高位消防水箱的設置高度問題
Height of the height of the fire water tank set
根據有關部門的規定：重力自流的消防水箱應設置在建筑的高部位，且要求能滿足不利點消火栓栓口靜壓的要求。高位消防水箱的設置高度應該不利點消火栓靜水壓力。當建筑高度不超過100米時，高層建筑消火栓不利點的靜水壓力不應低于0.07Mpa;當建筑高度超過100米時，高層建筑消火栓不利點的靜水壓力不應低于0.15Mpa.因此，高位消防水箱的設置高度一定要符合靜水壓力的需求和生產標準。
According to the provisions of the relevant departments: gravity fire water tank should set in the highest part of a building and can meet the requirements of the worst point hydrant mouth pressure. High fire tank height should ensure that the most unfavorable point fire hydrant hydrostatic pressure. When the building height not more than 100 meters, high-rise building fire hydrant at the most unfavorable point of hydrostatic pressure should not be less than 0.07MPa; when the building height of more than 100 meters, high-rise building fire hydrant at the most unfavorable point of hydrostatic pressure should not less than 0.15Mpa. so high place fire protection water tank height must be in line with the hydrostatic pressure of demand and production standards. 消防水箱如何防凍？
Height of the height of the fire water tank set.
以下是防凍要求：
The following is an anti freezing requirement:
(1)消防用水與生產、生活用水合用一個水池時，應有消防用水不作他用的技術措施。
when the fire water and the production and life use a water tank, it should ensure that the fire water is not used as a technical measure for him.
(2)為了火場供水的可靠性，當計算出的消防水池容積小于36m^3時，仍應采用36m^3;為了清池、檢修、換水時的消防應急用水，消防水池的總容積超過1000m^3（高層建筑消防水池的總容積超過50Om^3)時，應分設成兩個獨立使用的消防水池。
in order to ensure the reliability of the fire water supply, when calculated the volume of fire water tank is less than 36m^3, still should be the 36m^3; in order to ensure the pool cleaning, maintenance, and water for fire emergency water and fire pool of total volume of more than 1 O00m3 (high-rise building fire water tank
The total volume of more than 50Om^3), should be divided into two independent use of the fire pool.
(3)消防水池的補水時間，不宜超過48h，缺水地區可延長至96h。
the fire water pool of the time, should not be more than 48h, water shortage area can be extended to 96h.
(4)消防水池的儲備量包括室外消防用水量時，其水池應符合有關要求。
the amount of water in the fire pool, including the amount of water used for outdoor fire protection, shall be in accordance with the relevant requirements.
(5)消防水池設計應池內水經常流動，以防腐化變質。
the design of fire water tank water should ensure that often flow, to prevent corruption.
(6)寒冷地區的消防水池應有防凍設施口在儲罐區應有易燃，可燃液體不流入消防水池的設施。
the fire pool in the cold area should be anti freezing facilities in the storage tank area should be guaranteed to be flammable, flammable liquid does not flow into the fire pool facilities.
結論與建議
Conclusion and suggestion
（1）建議三本規范對高位消防水箱儲水量和設置高度采用同一原則，即消防水箱應滿足火災初期供水不利樓層和部位消防水壓和水量的要求。
  it is recommended that the three specifications of the high fire tank water storage and setting height of the same principle, that is, the fire tank should meet the fire early water supply the   most unfavorable floor and parts of fire water pressure and water requirements.
（2）高位消防水箱的儲水量應該與實際的消防火災中的供水需求總量來生產制作，建議消防水箱儲水量應滿足60s消防系統所需2支水箱和4只噴頭的用水量。
  high fire water tank of water storage should be with the actual fire water demand to production, suggested that the fire water storage tank water should meet the 60s fire system required 2 tank and four nozzle of water.
（3）消防水箱設置高度應滿足火災初期消防系統不利點所需要的低工作壓力。
  the fire water tank setting height should meet the minimum working pressure of the fire protection system at the most unfavorable point.
（4）設置常高壓給水系統并能不利點消火栓和自動噴水滅火系統等的水量和水壓的建筑物，如果出現此種情況可以不設消防水箱。
   set constant high pressure water supply system and to ensure the most unfavorable point fire hydrant and sprinkler system water and water pressure building, if such a situation can not set fire water tank.
