消防系统种类介绍

来源:http://www.cx-fire.com/ 日期:2024-06-07

消防设备分为三大类:水消防系统;气体消防系统;泡沫灭火系统;

Fire protection equipment is divided into three categories: water fire protection systems; Gas fire protection system; Foam fire extinguishing system;

1.水消防系统:水是常用的灭火剂,且水便宜,灭火效果好;灭火原理:水冷却作用,并穿透燃烧物来灭火。

1. Water fire protection system: Water is a commonly used fire extinguishing agent, and water is cheap and has good fire extinguishing effects; Fire extinguishing principle: Water cools and penetrates through combustibles to extinguish the fire.

A.消火栓给水系统(室内消火栓、室外消火栓系统)

A. Fire hydrant water supply system (indoor fire hydrant, outdoor fire hydrant system)

B.自动喷水灭火系统(闭式自动喷水灭火系统、预作用喷水系统、雨淋自动喷水系统)

B. Automatic sprinkler system (closed automatic sprinkler system, pre action sprinkler system, deluge sprinkler system)

2.气体消防系统

2. Gas fire protection system

A.气体灭火工作原理:当防护区发生火灾时,由火灾探测器向灭火控制盘发出信号,灭火控制控制声光报警盒,发出撤离报警信号,并控制联动设备(风机、空调等)。延时(0-30s)后,发出灭火指令,打开驱动气体瓶组,释放驱动气体,打开相应防护区的选择阀和灭火剂瓶组的容器阀,释放灭火剂,实施灭火。

A. Working principle of gas fire extinguishing: When a fire occurs in the protected area, the fire detector sends a signal to the fire extinguishing control panel, the fire extinguishing control controls the sound and light alarm box, sends an evacuation alarm signal, and controls the linkage equipment (fans, air conditioning, etc.). After a delay of 0-30 seconds, issue a fire extinguishing command, open the drive gas cylinder group, release the drive gas, open the selection valve of the corresponding protection zone and the container valve of the fire extinguishing agent cylinder group, release the fire extinguishing agent, and implement the fire extinguishing.

B.气体灭火系统组成:主要由灭火剂瓶组(包括灭火剂瓶组、容器阀)、驱动气体瓶组(包括启动瓶、容器阀)、连接管、单向阀、集流管、泄放装置、选择阀(适用于组合分配系统)、减压装置(适用于IG541气体灭火系统)、信号反馈装置、低泄高封阀、喷嘴、管道及其连接件等构成。配以自动灭火探测和控制设备,系统能自动运行启动,同时根据需要还可以实现当地或远距离手动启动。

B. Gas fire extinguishing system composition: mainly composed of fire extinguishing agent bottle group (including fire extinguishing agent bottle group, container valve), driving gas bottle group (including starter bottle, container valve), connecting pipe, one-way valve, manifold, safety release device, selection valve (suitable for combination distribution system), pressure reducing device (suitable for IG541 gas fire extinguishing system), signal feedback device, low release and high seal valve, nozzle, pipeline and its connecting parts, etc. Equipped with automatic fire detection and control equipment, the system can automatically operate and start, and can also be manually started locally or remotely as needed.

C.气体灭火系统分类:七氟丙烷灭火系统、IG541灭火系统、气溶胶、超细干粉

C. Classification of gas fire extinguishing systems: heptafluoropropane fire extinguishing system, IG541 fire extinguishing system, aerosol, ultrafine dry powder

3.泡沫系统:完整的泡沫灭火系统由消防泵、泡沫贮罐、比例混合器、泡沫产生装置、阀门及管道、电气控制装置组成。泡沫灭火系统按泡沫液的发泡倍数的不同分低倍数、中倍数及高倍泡沫灭火系统。泡沫灭火系统泡包括:泡沫罐、高倍数泡沫发生器、隧道用“泡沫消火栓箱”、网形低倍泡沫喷头、筒形低倍泡沫喷头、泡沫枪、泡沫消火栓箱、低倍泡沫产生器、泡沫消火栓、等全套产品。

3. foam system: a complete foam fire extinguishing system consists of fire pump, foam storage tank, proportioner, foam generation device, valve and pipeline, and electrical control device. The foam extinguishing system can be divided into low multiple, medium multiple and high multiple foam extinguishing systems according to the different foaming times of foam liquid. Foam extinguishing system foam includes: foam tank, high expansion foam generator, "foam fire hydrant box" for tunnel, mesh low expansion foam nozzle, barrel low expansion foam nozzle, foam gun, foam fire hydrant box, low expansion foam generator, foam fire hydrant, etc.
