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.
根据《建筑设计消防规范》的规定，消防水箱可以储存10分钟的储水量，当消防用水量小于低于25毫升的时候，经计算消防水箱所需消防储水量大于12m3时，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.
高位消防水箱的设置高度问题
Height of the height of the fire water tank set
根据有关部门的规定：重力自流的消防水箱应设置在建筑的高部位，且要求能满足不利点消火栓栓口静压的要求。高位消防水箱的设置高度应该不利点消火栓静水压力。当建筑高度不超过100米时，高层建筑消火栓不利点的静水压力不应低于0.07Mpa;当建筑高度超过100米时，高层建筑消火栓不利点的静水压力不应低于0.15Mpa.因此，高位消防水箱的设置高度一定要符合静水压力的需求和生产标准。
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.
消防水箱如何防冻？
Height of the height of the fire water tank set.
以下是防冻要求：
The following is an anti freezing requirement:
(1)消防用水与生产、生活用水合用一个水池时，应有消防用水不作他用的技术措施。
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)为了火场供水的可靠性，当计算出的消防水池容积小于36m^3时，仍应采用36m^3;为了清池、检修、换水时的消防应急用水，消防水池的总容积超过1000m^3（高层建筑消防水池的总容积超过50Om^3)时，应分设成两个独立使用的消防水池。
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)消防水池的补水时间，不宜超过48h，缺水地区可延长至96h。
the fire water pool of the time, should not be more than 48h, water shortage area can be extended to 96h.
(4)消防水池的储备量包括室外消防用水量时，其水池应符合有关要求。
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)消防水池设计应池内水经常流动，以防腐化变质。
the design of fire water tank water should ensure that often flow, to prevent corruption.
(6)寒冷地区的消防水池应有防冻设施口在储罐区应有易燃，可燃液体不流入消防水池的设施。
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. 结论与建议
Conclusion and suggestion
（1）建议三本规范对高位消防水箱储水量和设置高度采用同一原则，即消防水箱应满足火灾初期供水不利楼层和部位消防水压和水量的要求。
  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）高位消防水箱的储水量应该与实际的消防火灾中的供水需求总量来生产制作，建议消防水箱储水量应满足60s消防系统所需2支水箱和4只喷头的用水量。
  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）消防水箱设置高度应满足火灾初期消防系统不利点所需要的低工作压力。
  the fire water tank setting height should meet the minimum working pressure of the fire protection system at the most unfavorable point.
（4）设置常高压给水系统并能不利点消火栓和自动喷水灭火系统等的水量和水压的建筑物，如果出现此种情况可以不设消防水箱。
   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.
