（1）根据所使用的喷头类型，可分为闭式系统和开式系统。
(1) According to the type of nozzle used, it can be divided into closed system and open system.
闭式喷头，有释放机构，平时喷头出水口用释放机构封闭住，灭火时，释放机构自动脱落，开启喷头喷水。喷头一旦开放，便不能自动恢复原状。而开式喷头没有释放机构，喷水口是敞开的，管路中是自由空气，喷头可重复使用。
Closed nozzle, with a release mechanism. The outlet of the nozzle is usually sealed with a release mechanism. When extinguishing a fire, the release mechanism automatically comes off and the nozzle is turned on to spray water. Once the nozzle is opened, it cannot automatically return to its original state. The open nozzle does not have a release mechanism, the spray nozzle is open, and there is free air in the pipeline. The nozzle can be reused.
（2）根据系统的用途和配置状况，可分为湿式系统、干式系统、预作用系统、防护冷却系统、雨淋系统、水幕系统（防火分隔水幕和防护冷却水幕）、自动喷水-泡沫联用系统等。
(2) According to the purpose and configuration of the system, it can be divided into wet system, dry system, pre action system, protective cooling system, deluge system, water curtain system (fire separation water curtain and protective cooling water curtain), automatic sprinkler foam combined system, etc.
四、湿式自动喷水灭火系统
4、 Wet automatic sprinkler fire extinguishing system
（1）组成：由闭式喷头、湿式报警阀组、水流指示器或压力开关、供水与配水管道以及供水设施等组成。
(1) Composition: It consists of a closed nozzle, a wet alarm valve group, a water flow indicator or pressure switch, water supply and distribution pipelines, and water supply facilities.
（2）定义：准工作状态时配水管道内充满用于启动系统的有压水的闭式系统。
(2) Definition: A closed system in which the water distribution pipeline is filled with pressurized water for starting the system in a quasi working state.
特点：采用闭式喷头的灭火系统；准工作状态下管网中充满有压水；当喷头保护范围内发生火灾，喷头热敏元件受热达到或超过公称动作温度时，热敏元件动作（熔化、破碎），从而喷头开启，出水灭火，同时系统自动启动。
Features: Adopting a closed nozzle fire extinguishing system; Under quasi working conditions, the pipeline network is filled with pressurized water; When a fire occurs within the protection range of the nozzle, and the thermal element of the nozzle is heated to or exceeds the nominal operating temperature, the thermal element will act (melt or break), causing the nozzle to open, water to extinguish the fire, and the system will automatically start.
（3）适用范围
(3) Applicable scope
设置早期抑制快速响应喷头的仓库及类似场所，环境温度不低于4℃且不高于70℃的场所，应采用湿式系统。
Warehouses and similar places with early suppression and rapid response nozzles, and places with ambient temperatures not lower than 4 ℃ and not higher than 70 ℃, should use wet systems.
五、干式自动喷水灭火系统
5、 Dry automatic sprinkler fire extinguishing system
（1）组成：由闭式喷头、干式报警阀组、水流指示器或压力开关、供水与配水管道、充气设备以及供水设施等组成。
(1) Composition: It consists of a closed nozzle, a dry alarm valve group, a water flow indicator or pressure switch, water supply and distribution pipelines, inflation equipment, and water supply facilities.
（2）定义：准工作状态时配水管道内充满用于启动系统的有压气体的闭式系统。
(2) Definition: A closed system in which the water distribution pipeline is filled with pressurized gas used to start the system in a quasi working state.
特点：采用闭式喷头的灭火系统；准工作状态时配水管道中充满有压气体；当喷头保护范围内发生火灾，喷头热敏元件受热达到或超过公称动作温度时，热敏元件动作（熔化、破碎），从而喷头开启，系统开始排气充水，启动方式类似湿式系统。
Features: Adopting a closed nozzle fire extinguishing system; When in quasi working condition, the water distribution pipeline is filled with pressurized gas; When a fire occurs within the protection range of the nozzle, and the thermal sensitive components of the nozzle are heated to or exceed the nominal operating temperature, the thermal sensitive components will act (melt or break), causing the nozzle to open, and the system will begin to exhaust and fill with water. The starting method is similar to a wet system.
（3）适用范围
(3) Applicable scope
环境温度低于4℃或高于70℃的场所，应采用干式系统。
Places with ambient temperatures below 4 ℃ or above 70 ℃ should adopt dry systems.
六、预作用自动喷水灭火系统
6、 Pre action automatic sprinkler fire extinguishing system
（1）组成：由闭式喷头、预作用装置、水流报警装置、供水与配水管道、充气设备和供水设施等组成。
(1) Composition: It consists of a closed nozzle, pre action device, water flow alarm device, water supply and distribution pipeline, inflation equipment, and water supply facilities.
（2）定义：准工作状态时配水管道内不充水，发生火灾时由火灾自动报警系统、充气管道上的压力开关联锁控制预作用装置和启动消防水泵，向配水管道供水的闭式系统。
(2) Definition: A closed system in which the water distribution pipeline is not filled with water in the quasi working state. In the event of a fire, the fire automatic alarm system, the pressure switch interlocking control pre action device on the inflation pipeline, and the start of the fire water pump are used to supply water to the water distribution pipeline.
特点：采用闭式喷头的灭火系统；准工作状态时配水管道中不充水；当发生火灾时，由火灾自动报警系统和充气管道上的压力开关连锁控制预作用装置和启动消防水泵，并转化为湿式系统;与湿式系统、干式系统的不同之处在于，系统采用预作用装置，并配套设置火灾自动报警系统。
Features: Adopting a closed nozzle fire extinguishing system; When in quasi working condition, the water distribution pipeline is not filled with water; When a fire occurs, the fire automatic alarm system and the pressure switch on the inflation pipeline interlock to control the pre action device and start the fire water pump, and convert it into a wet system; The difference between wet and dry systems is that the system adopts a pre action device and is equipped with a fire automatic alarm system.
（3）适用范围
(3) Applicable scope
具有下列要求之一的场所，应采用预作用系统：
Places with one of the following requirements should adopt a pre action system:
1）系统处于准工作状态时严禁误喷的场所。（单连锁）
