来源：http://www.cx-fire.com/ 日期：2023-02-02
根据不同的建筑类型，可分为低层建筑室内消火栓系统供水和高层建筑室内消火栓供水系统。低层建筑和高层建筑的供水方式可以细分。消防给水和消火栓系统的相关知识点每年约为40分，因此知识点非常重要。下面就相关知识点做以下总结，

According to different building types, it can be divided into indoor fire hydrant system water supply for low-rise buildings and indoor fire hydrant water supply system for high-rise buildings. The water supply modes of low-rise buildings and high-rise buildings can be subdivided. The relevant knowledge points of fire water supply and hydrant system are about 40 points per year, so the knowledge points are very important. The following is a summary of relevant knowledge points, and Sichuan Xiaobian will answer for you.
低层建筑室内消火栓给水系统的给水方式分为：
The water supply modes of indoor fire hydrant water supply system in low-rise buildings are divided into:
(1)直接给水。
(1) Direct water supply.
(2)消防水泵和消防水箱的供水方式。
(2) Water supply mode of fire pump and fire water tank.
室内消火栓给水系统的给水方式分为：
The water supply mode of indoor fire hydrant water supply system is divided into:
(1)部分区域的消防供水方式：整个建筑采用一个区域供水，系统简单，设备少。高层建筑低消火栓螺栓处的静水压力不大于1.0MPa系统工作压力不大于2.40MPa这种供水方式可用于时间。
(1) Fire water supply mode in some areas: the whole building uses one area for water supply, with simple system and few equipment. The hydrostatic pressure at the bolt of low fire hydrant in high-rise buildings is not more than 1.0MPa, and the system working pressure is not more than 2.40MPa. This water supply method can be used for time.
(2)分区消防给水方式:高层建筑低消火栓栓口静水压力大于l.00MPa或者系统工作压力大于2.40MPa当时，应采用分区供水系统。分区供水形式应根据系统压力、建筑特点、综合技术经济、可靠性等因素确定。消防泵可平行或串联、减压水箱和减压阀，但当系统工作压力大于时2.4MPa消防水泵串联或减压水箱分区应采用供水形式。
(2) Zoned fire water supply mode: when the hydrostatic pressure at the low fire hydrant port of high-rise buildings is greater than 1.00MPa or the system working pressure is greater than 2.40MPa, the zoned water supply system shall be adopted. The form of district water supply shall be determined according to the system pressure, building characteristics, comprehensive technical economy, safety and reliability and other factors. The fire pump can be connected in parallel or in series with pressure reducing water tank and pressure reducing valve, but when the system working pressure is greater than 2.4MPa, the fire pump can be connected in series or the pressure reducing water tank can be divided into sections.
(1)消防泵串联供水时，应采用消防泵转运水箱串联供水，并符合下列规定:
(1) When the fire pump is used for water supply in series, the fire pump transfer tank shall be used for water supply in series, and the following provisions shall be met:
①采用消防转运水箱串联时，转运水箱的有效储水量不得小于60m3，转移水箱可用作高位消防水箱。
① When the fire transfer tank is used in series, the effective water storage capacity of the transfer tank shall not be less than 60m3, and the transfer tank can be used as a high-level fire water tank.
②串联转运水箱的溢流管应连接到消防水池。
② The overflow pipe of the tandem transfer tank shall be connected to the fire pool.
③当消防泵直接串联时，应采取措施确保供水可靠性，消防泵应从低到高依次启动。
③ When the fire pump is directly connected in series, measures shall be taken to ensure the reliability of water supply, and the fire pump shall be started from low to high.
④消防泵直接串联时，应检查系统的供水压力，并在串联消防泵出水管上设置减压倒流预防器。
④ When the fire pump is directly connected in series, the water supply pressure of the system shall be checked, and the pressure reducing backflow preventer shall be set on the outlet pipe of the fire pump in series.
(2)减压阀减压分区供水应符合下列规定:
(2) The water supply for pressure reducing zone of pressure reducing valve shall meet the following requirements:
①消防给水中使用的减压阀应可靠，并应满足消防给水的要求。
① The pressure reducing valve used in fire water supply shall be safe and reliable, and shall meet the requirements of fire water supply.
②减压阀应根据消防给水设计流量和压力进行选择，设计流量应在减压阀流量压力特性曲线的有效段内，减压阀出口动压不得小于设计值的65%。
② The pressure reducing valve shall be selected according to the design flow and pressure of fire water supply. The design flow shall be within the effective range of the pressure reducing valve flow characteristic curve. The dynamic pressure at the outlet of the pressure reducing valve shall not be less than 65% of the design value.
③每个供水分区应设置不少于两个减压阀组，每个减压阀组应设置备用减压阀。等等。
③ Each water supply zone shall be equipped with at least two pressure reducing valve groups, and each pressure reducing valve group shall be equipped with standby pressure reducing valve. wait.
(3)减压水箱减压分区供水应符合下列规定:
(3) The water supply in the pressure reducing zone of the pressure reducing water tank shall meet the following requirements:
①减压水箱的安装应符合高位消防水箱的有关规定。
① The installation of pressure reducing water tank shall comply with the relevant provisions of high level fire water tank.
②减压水箱进水管应设置防冲击和溢流技术措施，进水管应设置紧急关闭阀，溢流水应返回消防水池。等等。
② The inlet pipe of the pressure reducing water tank shall be equipped with technical measures to prevent impact and overflow. The inlet pipe shall be equipped with emergency shutdown valve. The overflow water shall return to the fire pool. wait.
