气体灭火 装置（电磁型）由灭火剂储瓶、容器阀、喷嘴、电磁型驱动装置、信号反馈装置、悬挂支架等组成，不需安装灭火剂输送管道，不需设置专用的储瓶间，采用悬挂或壁挂式安装，当火灾发生时，直接向防护区喷射灭火剂，灭火剂无管路损失，灭火速度更快、效率更高。 Suspended heptafluoropropane gas fire extinguishing device (electromagnetic type) is composed of fire extinguishing agent storage bottle, container valve, nozzle, electromagnetic driving device, signal feedback device, hanging bracket, etc. It is not necessary to install fire extinguishing agent delivery pipeline, and it is not necessary to set up a special storage bottle It adopts hanging or wall-mounted installation. When a fire occurs, the fire extinguishing agent is directly sprayed into the protective area. The fire extinguishing agent has no pipeline loss, and the fire extinguishing speed is faster and more efficient. The device has two start modes: automatic and manual.
气体灭火 装置主要适用于以下火灾： Hanging heptafluoropropane gas fire extinguishing device is mainly suitable for the following fires:
固体表面火灾； 1) Fire on solid surface;
液体火灾； 2) Liquid fire;
灭火前能切断气源的气体火灾； 3) A gas fire that can cut off the gas source before extinguishing the fire;
电气火灾； 4) Electrical fire;
Mainly applicable to electronic computer rooms, data processing centers, telecommunications and communication facilities, process control centers, expensive medical facilities, valuable industrial equipment, museums and art galleries, libraries, archives, valuables warehouses, emergency power facilities, flammable liquids Fire protection in key areas such as storage areas and clean workshops can also be used in production hazardous areas such as spray paint production lines, electrical aging rooms, rolling machines, printing presses, melting tanks, drying equipment, and coal in cement production processes. Powder silos, as well as ship cabins and cargo holds. Particularly suitable for tight spaces.
Suspended heptafluoropropane gas fire extinguishing device can be separately set up to protect a smaller area, or multiple protected areas can be used in combination to protect a larger space.
3 fire extinguishing agent
HFC-227 ea）作为灭火剂。 This device uses heptafluoropropane ( HFC-227 ea) as fire extinguishing agent. 对大气臭氧层无破坏作用（ ODP 值为零），符合环保要求 ，在大部分保护区域，灭火浓度均低于人体的无毒性反应浓度（NOAEL浓度），对人体是安全的，是一种优秀的洁净气体灭火剂。 Heptafluoropropane is mainly used for chemical fire extinguishing, and it also has physical fire extinguishing effect. It is colorless, odorless, clean, non-conductive, does not pollute the protected object, will not cause damage to property and precision facilities, and will not damage the atmospheric ozone layer ( ODP value is zero) ), In line with environmental protection requirements , in most protected areas, the fire extinguishing concentration is lower than the non-toxic reaction concentration (NOAEL concentration) of the human body, which is safe for the human body and is an excellent clean gas fire extinguishing agent.
This device has two startup modes: automatic startup mode and manual startup mode. As the device is installed in the protective area, it is wall-mounted or suspended. Under the premise of no reliable protection, the mechanical emergency operation start mode should not be used.
报警控制系统一般配有两种不同类型的火灾探测器。 Gas fire alarm control systems are generally equipped with two different types of fire detectors. The control host has "automatic" and "manual" switching functions (you can also set a switching switch outside the protection zone). When it is placed in the "automatic" position, the fire extinguishing device is in an automatic state.
When only one type of detector sends out a fire signal, the control host activates an alarm bell or an audible and visual alarm to notify the fire, but does not activate the fire extinguishing device. When the two detectors send out a fire signal, the control host activates the alarm bell and audible and visual alarm, and closes the opening of the protective area in conjunction with the fire-fighting start delay. When the set delay time is reached, the fire-extinguishing device is automatically started. If it is found that the fire extinguishing device does not need to be started during the delay time of the discharge, press the "emergency stop" button outside the protective zone or on the controller to terminate the fire extinguishing instruction.
When the transfer switch is set to the "manual" position, the fire extinguishing device is in the manual state.
In this state, the detector sends out a fire signal and controls the host to activate the alarm bell and sound and light alarm to notify the fire, but does not activate the fire extinguishing device. At this time, press the "Manual Start" or "Emergency Start" button outside the protective zone or on the controller to start the fire extinguishing device.
Note: Regardless of whether the control panel is in the automatic or manual state, press the "Emergency Start" and "Manual Start" buttons to start the fire extinguishing device.
