Description

Przyrzady do gaszenia plonacej ben¬ zyny lub innych weglowodorów opieraja sie na stosowaniu czterochlorku wegla lub piany wytwarzanej dzialaniem kwasu we¬ glowego na ciala, które z natury swej po¬ siadaja zdolnosc pienienia sie (mydlenia), jak np. drzewo panamskie, lukrecjowe i t. A Aparaty podobne wymagaja zawsze stosowania pompy lub zmieszania dwu cie¬ czy w chwili uzycia, do czego nalezy stoso¬ wac urzadzenia o budowie zlozonej, która utrudnia nalezyta konserwacje aparat.1..Aparat stanowiacy przedmiot wynalaz¬ ku niniejszego usuwa obie te niedogodnosci, poniewaz nie posiada ani pompy, ani me¬ chanizmu wewnetrznego, ani tez jakiego¬ kolwiek urzadzenia wlasciwego, zawiera¬ jacego ciecz.Cel wynalazku niniejszego osiaga sie w ten sposób, iz wewnatrz gasnicy umieszcza sie mieszanine ciekla o podwój¬ nej wlasnosci, t, j. majaca zdolnosc ga¬ szenia i posiadajaca, w temperaturze uzy¬ cia, preznosc pary, która zapewnia jej wy¬ trysk nazewnatrz. Mieszanina podobna sklada sie: z 90% — 100% bromku metylo¬ wego, którego temperatura wrzenia wyno¬ si 13°C (wedlug Fremy) i z 10%—0% cie¬ czy gaszacej (czterochlorku wegla, trój¬ chlorku etylenu, trieliny).Zalaczony rysunek uwidocznia przy¬ klad aparatu zbudowanego wedlug wyna¬ lazku. Fig. 1 przedstawia widok i cze-sciowy przekrój zprzodu, fig. 2—widok ze¬ wnetrzny ztylu.Ararat sklada sia zasadniczo ze zbiór- nika a w postaci walca mosieznego, zaopa¬ trzonego u góry w oprawke 6, w której za- pomoca gwintu zamocowuje sie rurke c, wyposazona w wyplywowy kanal srodkom wy d, zwezony w swej czesci górnej. Pier¬ scien plastyczny e, umieszczony miedzy rurka e i oprawka b, uszczelnia zlacze.Kanal d w polozeniu normalnem za¬ mkniety jest klapa / z kauczuku lufo innego tworzywa, która miesci sie wewnatrz kap¬ turka g, zaopatrzonego w raczke h osa¬ dzona wahliwie w punkcie i pokrywy /, która nakreca sie na górna czesc rurki c i zamocowuje przeciwnakretka k. Sprezyna / jednym koncem opiera sie o rurke c, dru¬ gim zas — dociska raczke h, przyciskajac w ten sposób klapke / do wylotu rurki c.Aparat dziala w sposób nastepujacy: trzymajac aparat w rece, wystarczy naci¬ snac palcem wskazujacym lub wielkim raczke h, aby natychmiast wytrysnal stru¬ mien cieczy gaszacej, który siega na kilka metrów.Zdolnosc gaszenia cieczy stosowanej w tym wypadku przewyzsza wszystkie ciecze dotychczas znane, a to dzieki niskiej tem¬ peraturze wrzenia bromku metylowego (wedlug Fremy 13°) i dzieki pochlanianiu wskutek parowania tegoz produktu znacz¬ nej ilosci ciepla wewnatrz plomienia. Ci¬ snienie niezbedne do wytrysku strumienia gaszacego wytwarza sie wylacznie wsku¬ tek preznosci pary mieszaniny zawartej w zbiorniku zamknietym a.Opisany zawór mozna zmieniac zaleznie od celu do jakiego ma sluzyc aparat; do celów awjatyki moze sie on skladac z tlocz¬ ka obciazonego sprezyna, zamykajacego dwie lub wiecej malenkich rurek, które umozliwiaja polewanie (zraszanie) jednego lub kilku nawe^laczy bez wspóludzialu pi¬ lota. Zwykly nacisk na tloczysko tloka wy¬ starczy do uruchomienia aparatu i natych¬ miastowego ugaszenia pozaru* PL PLDevices for extinguishing fiery gasoline or other hydrocarbons are based on the use of carbon tetrachloride or foam produced by the action of carbon acid on the body, which inherently have a foaming (soapy) capacity, such as, for example, Panama wood, liquorice, etc. A similar devices always require the use of a pump or the mixing of two liquids at the time of use, for which devices of a complex structure which make it difficult to properly maintain the device should be used.1 The device of the present invention eliminates both of these disadvantages. since it has neither a pump, nor an internal mechanism, nor any specific device containing a liquid. The purpose of the present invention is achieved by placing a liquid mixture inside the fire extinguisher with a double property, i.e. having an extinguishing capacity and having, at the temperature of use, a vapor pressure which allows it to escape to the outside. A similar mixture consists of: 90% - 100% methyl bromide with a boiling point of 13 ° C (according to Frema) and 10% to 0% of the quenching liquid (carbon tetrachloride, ethylene trichloride, trielin) The attached drawing shows an example of an apparatus constructed according to the invention. Fig. 1 is a front view and a partial sectional view, Fig. 2 is an external view of the rear. The ararat consists essentially of a collection, in the form of a brass cylinder, provided at the top with a holder 6 in which it is threaded. a c-tube is attached, equipped with an outflow channel to the discharge means, narrowed in its upper part. The plastic ring e, placed between the tube e and the socket b, seals the joint. The channel in its normal position is closed by a flap / made of rubber or other material, which is inside the cap g, fitted with a handle and pivotally mounted in At the point and the cover /, which winds onto the upper part of the tube c, is fixed by a counter nut k. The spring / one end rests against the tube c, while the other - presses the handle h, thus pressing the flap / against the tube outlet c. The device works in as follows: holding the apparatus in the hand, it is enough to press the index finger or the big handle h to immediately shoot a stream of extinguishing liquid, which reaches a few meters. The extinguishing capacity of the liquid used in this case exceeds all liquids known so far, thanks to the low boiling point of methyl bromide (according to Frema 13 °) and due to the evaporation of this product absorbing a large amount of heat inside the flame. The pressure necessary for the spray of the extinguishing jet is created solely by the vapor pressure of the mixture contained in the closed vessel a. The described valve can be changed depending on the purpose for which the apparatus is to be used; for aviation purposes, it may consist of a spring loaded piston that encloses two or more tiny tubes which allow the watering (sprinkling) of one or more nodes without the use of a saw. A simple pressure on the piston rod will be enough to start the apparatus and immediately extinguish the fire * PL EN
