瓶组一般由容器、容器阀、泄放装置、虹吸管、取样口、检漏装置和充装介质等组成，用于贮存灭火剂和控制灭火剂的施放。

Bottle groups are generally composed of containers, container valves, safety relief devices, siphons, sampling ports, leak detection devices, and filling media, used to store and control the release of fire extinguishing agents.

（二）容器

（2） Container

容器是用来储存灭火剂和启动气体的重要组件，分为钢质无缝容器和钢质焊接容器。

Containers are important components used to store fire extinguishing agents and starting gases, divided into seamless steel containers and welded steel containers.

（三）容器阀

（3） Container valve

容器阀又称瓶头阀，安装在容器上，具有封存、释放、充装、超压泄放（部分结构）等功能。

Container valve, also known as bottle head valve, is installed on the container and has functions such as sealing, releasing, filling, and overpressure relief (partial structure).

容器阀按用途分为灭火剂瓶组上容器阀和驱动气体瓶组上容器阀两类；按密封形式分为活塞密封和膜片密封两类；按结构形式分为膜片式、自封式、压臂式三类；按启动方式分为气动启动型、电磁启动型、电爆启动型、手动启动、机械启动型和组合启动型六类。

Container valves are divided into two categories based on their purpose: container valves on fire extinguishing agent bottle groups and container valves on driving gas bottle groups; According to the sealing form, it can be divided into two types: piston seal and diaphragm seal; Divided into three types according to structural form: diaphragm type, self sealing type, and pressure arm type; According to the starting method, it is divided into six categories: pneumatic starting, electromagnetic starting, electric explosion starting, manual starting, mechanical starting, and combination starting.

In a combined distribution system, the valve used to control the release of fire extinguishing agent through the pipeline network to a predetermined protective area or object, and the selection valve corresponds to the protective area one by one. The selection valve can be divided into piston type, ball valve type, pneumatic start type, electromagnetic start type, electric explosion start type, and combination start type.

（五）喷嘴

（5） Nozzle

喷嘴是用来控制灭火剂的流速和喷射方向的组件，是气体灭火系统的一个关键部件。喷嘴可分为全淹没灭火方式用喷嘴和局部应用灭火方式用喷嘴。局部应用灭火方式用喷嘴又分为架空型和槽边型喷嘴。

The nozzle is a component used to control the flow rate and direction of fire extinguishing agent, and is a key component of a gas fire extinguishing system. Nozzles can be divided into fully submerged fire extinguishing methods and locally applied fire extinguishing methods. The nozzles used for local fire extinguishing can be divided into overhead and slot edge nozzles.

(六）单向阀

（6） One-way valve

单向阀按安装在管路中的位置可分为灭火剂流通管路单向阀和驱动气体控制管路单向阀；按阀体内活动的密封部件型式可分为滑块型、球型和阀瓣型。

The one-way valve can be divided into one-way valves for fire extinguishing agent circulation pipeline and one-way valves for driving gas control pipeline according to its installation position in the pipeline; According to the types of sealing components that move within the valve body, they can be divided into slider type, ball type, and disc type.

灭火剂流通管路单向阀装于连接管与集流管之间，防止灭火剂从集流管向灭火剂瓶组返流。驱动气体控制管路单向阀装于启动管路上，用来控制气体流动方向，启动特定的阀门。

The one-way valve of the fire extinguishing agent circulation pipeline is installed between the connecting pipe and the collecting pipe to prevent the fire extinguishing agent from flowing back from the collecting pipe to the fire extinguishing agent bottle group. The one-way valve of the driving gas control pipeline is installed on the starting pipeline to control the direction of gas flow and activate specific valves.

（七）集流管

（7） Collecting pipe

集流管是将多个灭火剂瓶组的灭火剂汇集一起再分配到各防护区的汇流管路

The collecting pipe is a collection pipe that gathers the extinguishing agents from multiple sets of extinguishing agent bottles and distributes them to each protective zone

（八）连接管

（8） Connecting pipe

连接管可分为容器阀与集流管间连接管和控制管路连接管。容器阀与集流管间连接管按材料分为高压不锈钢连接管和高压橡胶连接管。

The connecting pipe can be divided into the connecting pipe between the container valve and the collecting pipe, and the connecting pipe for the control pipeline. The connecting pipes between the container valve and the collecting pipe are divided into high-pressure stainless steel connecting pipes and high-pressure rubber connecting pipes according to their materials.

（九）泄放装置

（9） Safety relief device

泄放装置装于瓶组和集流管上，以防止瓶组和灭火剂管道非正常受压时爆炸。瓶组上的泄放装置可装在容器上或容器阀上。

The safety relief device is installed on the bottle group and the collecting pipe to prevent explosion when the bottle group and fire extinguishing agent pipeline are not under normal pressure. The safety relief device on the bottle group can be installed on the container or on the container valve.

泄放装置可分为灭火剂瓶组泄放装置、驱动气体瓶组泄放装置和集流管泄放装置。

The safety relief device can be divided into fire extinguishing agent bottle group safety relief device, driving gas bottle group safety relief device, and manifold safety relief device.

（十）驱动装置

（10） Drive device

驱动装置用于驱动容器阀、选择阀使其动作。可分为气动型驱动器、引爆型驱动器、电磁型驱动装置、机械型驱动器和燃气型驱动器等类型。

（十一）检漏装置

（11） Leak detection device

检漏装置用于监测瓶组内介质的压力或质量损失。包括压力显示器、称重装置和液位测量装置等。

The leak detection device is used to monitor the pressure or mass loss of the medium in the bottle group. This includes pressure displays, weighing devices, and liquid level measurement devices.

（十二）信号反馈装置

（12） Signal feedback device

信号反馈装置是安装在灭火剂释放管路或选择阀上，将灭火剂释放的压力或流量信号转换为电信号，并反馈到控制中心的装置。常见的是把压力信号转换为电信号的信号反馈装置，一般也称为压力开关。

The signal feedback device is a device installed on the fire extinguishing agent release pipeline or selector valve, which converts the pressure or flow signal released by the fire extinguishing agent into an electrical signal and feeds it back to the control center. A common signal feedback device, also known as a pressure switch, converts pressure signals into electrical signals.

（十三）低泄高封阀

（13） Low discharge and high sealing valve

低泄高封阀是为了防止系统由于驱动气体泄漏的累积而引起系统的误动作而在管路中设置的阀门。它安装在系统启动管路上，正常情况下处于开启状态，只有进口压力达到设定压力时才关闭，其主要作用是排除由于气源泄漏积聚在启动管路内的气体。

Low leakage and high sealing valve is a valve installed in the pipeline to prevent system malfunction caused by the accumulation of driving gas leakage. It is installed on the system startup pipeline and is normally in an open state. It only closes when the inlet pressure reaches the set pressure. Its main function is to eliminate gas accumulated in the startup pipeline due to gas source leakage.
