    Heptafluoropropane gas automatic fire extinguishing system

    Heptafluoropropane gas automatic fire extinguishing system

    First, the system briefly
    1.1 Introduction
    Fire extinguishing system (FM200) is an internationally recognized environmental clean agents, suppliers CF3CHFCF3 (Figure 1.1-1) has been widely used in China and other parts of the world. Fire extinguishing agent (HFC-227ea) is a colorless, odorless gas, ozone depletion can (ODP) of zero, meet environmental requirements, with clean, low toxicity, high performance fire, non-conductive, small storage space, network pressure is low, after the fire pollution. The company's sales and installation of fire extinguishing system valve design straight big local yin force is small, different co-workers in a short time to meet the discharge requirements, design parameters intact, functional work is accurate and reliable, long-term does not leak, simple installation, operation and easy maintenance.
    1.2 Scope
    (1) can be put out A, B, C fires, safe and effective use in a place personnel;
    (2) there are places to store valuables and precious files, software and hardware facilities;
    (3) not to use water-based fire extinguishing agent places;
    (4) After the release of extinguishing agent residues difficult to clean places;
    (5) fire extinguishing agent storage space is limited, is required to achieve the effect of a place with a small fire extinguishing agent.
    * Telecommunications room, internet room, treasury, archives, bill compartment, power distribution room, generator room, storage room and so on.
    Second, the working principle and constitute
    2.1 extinguishing mechanism

    Mechanism of HFC-227ea fire extinguishing mechanism with Halon fire extinguishing agent series similar to a chemical fire Fan Zhi, by thermal decomposition of fluorinated extinguishing agent active free radicals react with the combustion process in the chain generated by H +, OH -, O2- active radical gas-phase reaction, thereby suppressing the combustion process in the chemical reaction continuously rapid elimination of free radicals during combustion to the implementation of fire.
    2.2 workflow
    Fire extinguishing system consists of fire detection and alarm systems, fire control systems, fire fighting equipment components (Figure 2.2-1)
    2.3 extinguishing system schematic
    A single non-self-extinguishing system (Figure 2.3-1)
    2. The composition distribution of fire-extinguishing system (Figure 2.3-2)
    2.4 startup mode
    Start mode fire extinguishing systems there are three: start automatically, manually start, mechanical emergency start.
    2.5 Taxonomy
    A protective area classification: a combination of the distribution system and unit independent systems;
    2, structural features Category: Pipe net fire extinguishing systems and fire extinguishing system without network (pre-extinguishing system).
    Third, the device classification
    3.1 No network fighting equipment

    (1) fire-fighting equipment hanging
    Hanging fire extinguishing agent storage device is the device, piping, nozzles, pressure signal, valves and other components to drive assembly sets, and the suspension of a fire extinguishing system installed.
    (2) fire-fighting equipment cabinet
    Cabinet is the fire extinguishing device storage devices, pipes, nozzles, pressure signal, a valve drive, fire detection components, controllers and other components assembled on a fire extinguisher bottle storage cabinet. Electromagnetic valve drive to start, start the power DC24V 1.2A. Bottle storage cabinet with a single bottle bottles cabinet cabinet double two.
    Mechanical devices require the use of fire-fighting and fire detectors, fire alarm fire control and other ancillary equipment. When there is a fire, temperature, smoke detector signal emitted by the fire after a logical analysis of the automatic fire alarm controller, ie composite audible alarm signal, also issued joint command, close linkage equipment, start solenoid valve drive open container valve, release the extinguishing agent, the implementation of fire; also press the emergency start button, the implementation of fire operations.
    (3) Technical parameters
    No pipe network fire extinguishing system is a prefabricated, total flooding fire extinguishing system, which has flexible installation, beautiful appearance, fire extinguishing agents no network loss, high extinguishing efficiency, fast start and so on. No network is no fire extinguisher bottle storage room, the bomb is set in the protected area. When the discharge of fire extinguishing equipment directly to the protected area, and convenient. Mainly applied to computer rooms, telecommunication centers, power distribution room, generator room and other protected areas in a
