(54) УСТАНОВКА ДЛЯ ТУШЕНИЯ ПОЖАРА Б ЗАКРЫТОМ ПОМеДЁНИИ(54) INSTALLATION FOR FIRE EXTINGUISHMENT WITH CLOSED REMEDY
На -чертеже изображена схема предлагаемой установки тушени пожара.The drawing shows a diagram of the proposed fire extinguishing installation.
Установка включает емкость I с огнетушашей жидкостью, например хладоном, доэнрукицую головку 2, установленную на емкости с смгнетушшаей жидкостью, емкость 3 с нейтральным газом, соединенную через запорный клапан 4 с дозирующей головкой, коллектор 5 с сопламираспылителгакш 6, дополнительную ем:-кость 7 с митральным газом через запорный клапан 8 соединенную с дополнительными коллекторами 9, имеюшими эжекторы 1О и расположенными в верхней и нижней зонах эш ищаемого помешени , устройство 11 сжгнализацни, которое через у1фавл ющее устройство 12 соединено с запорными клапанами 4 и 8 причем электрическа цепь управлени запорньА клапанс 4 8 содержит реле 13 времени.The installation includes a container I with a fire extinguisher liquid, such as freon, a doenrukitsy head 2 installed on a tank with smugent liquid, a tank 3 with a neutral gas connected through a check valve 4 with a dosing head, a collector 5 with nozzles sprayed 6, additional: -7 seconds by means of a mitral gas through a check valve 8 connected to additional manifolds 9, which have ejectors 1O and are located in the upper and lower zones of the search room, device 11 is squeezed, which through a fastening device 1 2 is connected to shut-off valves 4 and 8, wherein the electrical control circuit of the locking valve 4 8 contains a time relay 13.
Установка работает следующим образом .The installation works as follows.
При подаче устройством 11 сигнализации сигнала о пожаре или пожароопасной концентрации го1мочеро газа управлвкоцее устройство 12 подает команду на открытие клапана 4 емкости 3 и шслючение реле 13 . Нейтральный газ из емкос-т 3 подаётс в емкость t с хладоном, офазук ца с в дозируюшей головке 2 смесь нейтрального газа и хладона поступает в коллектор 5 и через его сопла-распылители. 6 попадает в помещение. Через заданный (3-5 мин) реле 13 времени дает команду от управл ющего устройСпаа 12 на открытие клапана 8 и нейтральный газ из дсшолнительной ем кости 7 подаетс в эжекторы Ю дополнительных коллекторов 9. Проход через них, нейтральный газ из нижних зон помещени захватывает осевшие пары хладона и направл ет их в в рхние зоны перемещени , а из верхних зон.захватывает горючий газ и направл ет его в нижние зоны помещени , перемешива таким образом горючий газ с компонентами огнетушащей смеси и создава однородную негорючую среду. Така среда поддерживаетс периодической или непрерывной подачей нейтрального газа через эжекторы до тех пор, пока существует пожароопасна ситуаци .When the device 11, the alarm signaling a fire or a fire hazard concentration of the first earth gas control unit 12 sends a command to open the valve 4 of the tank 3 and the relay 13. Neutral gas from tank 3 is fed into tank t with freon, ofazuka with in the dosing head 2 a mixture of neutral gas and freon enters the collector 5 and through its nozzles-sprayers. 6 enters the room. After a predetermined (3-5 min) time relay 13 gives a command from the control unit Spata 12 to open the valve 8 and the neutral gas from the additional capacitance 7 is supplied to the ejectors Yu of additional collectors 9. Passing through them, the neutral gas from the lower areas of the room captures the settled refrigerant vapors and directs them to the inner zones of movement, and from the upper zones. captures the combustible gas and directs it to the lower zones of the room, thus mixing the combustible gas with the components of the fire extinguishing mixture and creating a homogeneous noncombustible environment. This medium is maintained intermittently or continuously by supplying neutral gas through the ejectors as long as the fire situation exists.
