Description
Die Erfindung bezieht sich auf eine Rückschlagsicherung zum Aufhalten von Explosionen, insbesondere bei autogenen Schneid- und Schweißanlagen. Die bisher bekannten Konstruktionen derartiger Rückschlagsicherungen bei ähnlichen Anwendungsgebieten verwenden zum Schließen der Zuleitungsmündung Metallplatten, die als Membran wirken sollen.The invention relates to a kickback device for stopping explosions, especially with oxy-fuel cutting and welding systems. The previously known constructions of such kickback devices Use in similar areas of application to close the feed line mouth Metal plates intended to act as a membrane.
ίο Die bekannte Vorrichtung hat den Nachteil, daß dieselbe nur in einer Richtung arbeiten kann, da eine in vertikaler Richtung wirkende Metallplatte ohne große Änderung der Konstruktion nicht für eine horizontale Rieh'S tung zu verwenden ist. Ferner kann eine lose, auf einer Dichtungsfläche liegende Metallplatte niemals gasdicht halten, sobald zwischen Dichtungsfläche und aufliegender Metallplatte ein Fremdkörper eindringt. Nach der Erfindung werden diese Nachteile dadurch behohen, daß eine mit Gasdurchtrittsöffnungen versehene Membran, die aus elastischem Material hergestellt ist, von den Wänden einer in die Gasleitung eingeschalteten Kammer ge- 1-5 halten wird, wobei die Membran bei Flammenrückschlag die Mündung des Gaszuleitungsrohres in der Kammer verschließt.The known device has the disadvantage that it can only work in one direction, since a metal plate acting in the vertical direction cannot be used for a horizontal Rieh'S device without major changes in construction. Furthermore, a loose metal plate lying on a sealing surface can never hold gas-tight as soon as a foreign body penetrates between the sealing surface and the metal plate resting on it. According to the invention these disadvantages are characterized behohen that a provided with gas passage openings membrane which is made of elastic material, is maintained by the walls of a switched into the gas pipe chamber overall 1-5, wherein the membrane at flashback the mouth of the gas supply pipe in the chamber locks.
Die Erfindung ist in den Abb. ι bis 4 in einem Ausführungsbeispiel dargestellt, und zwar zeigen Abb. 1 einen senkrechten Schnitt durch die Membrankammer, Abb. 2 einen Schnitt nach der Linien-B in Abb. 1, Abb. 3 und 4 die Membran. In einer Kammer d, welche mit einer oder mehreren Gaszuführungen α und mit einer oder mehreren Gasabführungen e versehen sein kann, befindet sich eine Membran b, in welcher Öffnungen c, deren Zahl beliebig sein kann, angebracht sind. Die Öffnungen befinden sich um die Gaszuführung α und können ohne Rücksichtnahme auf die Gasabführung e an jeder Stelle in der Membran angebracht werden. Die Membran kann eine Verstärkung f erhalten.The invention is shown in Figs. 1 to 4 in an embodiment, namely Fig. 1 shows a vertical section through the membrane chamber, Fig. 2 a section along the line B in Fig. 1, Fig. 3 and 4 the membrane . In a chamber d, which can be provided with one or more gas inlets α and with one or more gas outlets e , there is a membrane b, in which openings c, the number of which can be any number, are attached. The openings are located around the gas inlet α and can be attached at any point in the membrane without taking into account the gas outlet e. The membrane can be given a reinforcement f .
Wirkungsweise: Das vom Gasbehälter kommende Gas tritt durch die Gaszuführung a unter die Membran b, strömt durch die in der Membran befindlichen öffnungen c in die Kammer d und wird durch, die Gasabführung e der Verbrauchsstelle zugeführt. Beim Zurücktreten des Gases oder bei Flammenrückschlägen schließt die Membran b die Gaszuführung α ab und verhindert damit den Rücktritt des Gases in den Gasbehälter.Mode of operation: The gas coming from the gas container passes through the gas inlet a under the membrane b, flows through the openings c in the membrane into the chamber d and is fed through the gas outlet e to the point of consumption. When the gas recedes or in the event of flashbacks, the membrane b closes the gas supply α and thus prevents the gas from withdrawing into the gas container.
