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.
低層建筑室內消火栓給水系統的給水方式分為：
The water supply modes of indoor fire hydrant water supply system in low-rise buildings are divided into:
(1)直接給水。
(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.
室內消火栓給水系統的給水方式分為：
The water supply mode of indoor fire hydrant water supply system is divided into:
(1)部分區域的消防供水方式：整個建筑采用一個區域供水，系統簡單，設備少。高層建筑低消火栓螺栓處的靜水壓力不大于1.0MPa系統工作壓力不大于2.40MPa這種供水方式可用于時間。
(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)分區消防給水方式:高層建筑低消火栓栓口靜水壓力大于l.00MPa或者系統工作壓力大于2.40MPa當時，應采用分區供水系統。分區供水形式應根據系統壓力、建筑特點、綜合技術經濟、可靠性等因素確定。消防泵可平行或串聯、減壓水箱和減壓閥，但當系統工作壓力大于時2.4MPa消防水泵串聯或減壓水箱分區應采用供水形式。
(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)消防泵串聯供水時，應采用消防泵轉運水箱串聯供水，并符合下列規定:
(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采用消防轉運水箱串聯時，轉運水箱的有效儲水量不得小于60m3，轉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串聯轉運水箱的溢流管應連接到消防水池。
② The overflow pipe of the tandem transfer tank shall be connected to the fire pool.
③當消防泵直接串聯時，應采取措施確保供水可靠性，消防泵應從低到高依次啟動。
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消防泵直接串聯時，應檢查系統的供水壓力，并在串聯消防泵出水管上設置減壓倒流預防器。
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)減壓閥減壓分區供水應符合下列規定:
(2) The water supply for pressure reducing zone of pressure reducing valve shall meet the following requirements:
①消防給水中使用的減壓閥應可靠，并應滿足消防給水的要求。
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減壓閥應根據消防給水設計流量和壓力進行選擇，設計流量應在減壓閥流量壓力特性曲線的有效段內，減壓閥出口動壓不得小于設計值的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每個供水分區應設置不少于兩個減壓閥組，每個減壓閥組應設置備用減壓閥。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)減壓水箱減壓分區供水應符合下列規定:
(3) The water supply in the pressure reducing zone of the pressure reducing water tank shall meet the following requirements:
①減壓水箱的安裝應符合高位消防水箱的有關規定。
① The installation of pressure reducing water tank shall comply with the relevant provisions of high level fire water tank.
②減壓水箱進水管應設置防沖擊和溢流技術措施，進水管應設置緊急關閉閥，溢流水應返回消防水池。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.
