Description
Vorrichtung zum Schutz gegen Rücktritt von, schleichendem Sauerstoff in vom Gasentwickler y zur Verbrauchsstelle führenden Gasleitungen bei autogenen Schweißanlagen Die Erfindung bezieht sich auf eine mit einer Membran versehene Schutzvorrichtung gegen Rücktritt von schleichendem Sauerstoff in vom Gasentwickler zur Verbrauchsstelle führenden Gasleitungen beiautogenen Schweißanlagen: Bei -einer solchen aus Gummi oder einem anderen elastischen Stoff hergestellten Membran besteht die Schwierigkeit; auch nAch dem Einbau eine ebene Fläche der Membran beizubehalten, so daß ein sicherer Abschluß der durch sie zu verschließenden Rohrmündung erreicht wird. Wird nämlich die Membran am Umfang durch Schrauben o. dgl. festgeklemmt, so bewirkt die Dehnung an der Druckstelle eine Krümmung der Membranfläche.Device to protect against the withdrawal of creeping oxygen in gas lines leading from the gas generator y to the point of consumption in the case of autogenous Welding systems The invention relates to a protective device provided with a membrane against withdrawal of creeping oxygen in from the gas generator to the point of consumption leading gas lines in autogenous welding systems: -one made of rubber or another elastic material made membrane, there is the difficulty; Maintain a flat surface of the membrane even after installation, so that a safer one Completion of the pipe mouth to be closed by it is achieved. Namely will the membrane is clamped on the circumference by screws or the like, thus causing the expansion a curvature of the membrane surface at the pressure point.
Bekannt ist es, dehnbare Membranplatten durch Flansche mit Schrauben festzuhalten oder auch durch Eindrücken von Rillen in entsprechende Nuten und die Spannung durch besondere Vorrichtungen, z. B. durch einen mit Schrauben ,angedrückten Ring, zu erreichen. Der Nachteil dieser Einrichtungen besteht einerseits in der umständlichen Bauart und andererseits darin, daß nicht eine gleichmäßige Anspannung für alle hergestellten Stücke erreicht wird.It is known to use expandable membrane plates by means of flanges with screws to hold or by pressing grooves into corresponding grooves and the Voltage by special devices, e.g. B. by one with screws, pressed Ring, reach. The disadvantage of these facilities is on the one hand in the cumbersome design and on the other hand in the fact that not an even tension for all manufactured pieces.
Es wird daher vorgeschlagen, die Einspannflansche der Membran oder die Einspannflansche und den M@embranrand als Anspannvorrichtungen für die Membran durch Schrägstellung der Seitenflächen der Einspan,nuten und -wulste auszubilden. Beispiele hierfür zeigen die Abb. i und 2: Nach Abb. i erhält die Membran einen ringförmigen Wulst, welcher in entsprechende Nuten der Einspannflansche eingreift. Die inneren Kanten dieser Nuten liegen vor dem Zusammenschrauben der Deckel auf einem Kreise größeren Durchmessers als die inneren Kanten des Wulstes. Bein Anpressen wird die Membran nuseinandergezogen.It is therefore proposed that the clamping flanges of the membrane or the clamping flanges and the membrane rim as tensioning devices for the membrane by inclining the side surfaces of the clamping, grooves and bulges to form. Examples of this are shown in Figs. I and 2: According to Fig. I, the membrane is given a annular bead which engages in corresponding grooves in the clamping flanges. The inner edges of these grooves rest on before the covers are screwed together a circle larger in diameter than the inner edges of the bead. Pressing the leg the membrane is pulled together.
Bei der Vorrichtung nach Abb.2 ist der eine Flansch mit einem Wulste und der andere Flansch mit einer entsprechenden Nut/, jedoch von größerer Breite als e, ausgerüstet. Vor dem Zusammenschrauben der beiden Flansche ist der Durchmesser g des Kreises, .auf welchem der Wulst liegt; kleiner als der Durchmesser h des Kreises, auf welchem die Nut liegt. Beim Anpressen wird die Membran aüseinandergezogen.In the device according to Fig. 2, one flange is with a bead and the other flange with a corresponding groove /, but of greater width as e, equipped. Before screwing the two flanges together, the diameter is g of the circle on which the bead lies; smaller than the diameter h of the circle, on which the groove lies. When pressed, the membrane is pulled apart.
