Description
Gegenstand der Erfindung· ist eine weitere Ausbildung des Sicherheitsventils für Gasleitungen, insbesondere zur Verhütung des Ausströmens von Gas beim Abfallen des Gas-Schlauches, nach, dem Hauptpatent 596 239. Die Erfindung bezweckt, die Betriebssicherheit und Zuverlässigkeit solcher mit einer Membran ausgebildeter Ventile zu erhöhen. Es hat sich in der Praxis gezeigt, daß Gummihäute, welche als Membran in eine Leitung für Leuchtgas gewisser Zusammensetzung eingeschaltet sirid, nach längerer oder kürzerer Zeit von chemischen Einflüssen zerstört werden können, so daß das Arbeiten des Ventils beeinträchtigt wird.The subject of the invention is a further design of the safety valve for gas pipes, in particular to prevent gas from escaping if the gas hose falls off, according to the main patent 596 239. The aim of the invention is operational safety and to increase the reliability of such diaphragm formed valves. It has been shown in practice that Rubber skins, which act as a membrane in a line for luminous gas of a certain composition switched on sirid, destroyed by chemical influences after a longer or shorter period of time can be so that the operation of the valve is impaired.
Zum Ersatz dieser Gummihaut wird in solchen Fällen eine Lederhaut verwendet, die aber weniger elastisch ist wie eine Gummihaut. Es kann dann der Fall eintreten, daß, nachdem das Ventil gewirkt hat und durch Druckstauung die Membran gegen den Sitz angepreßt worden ist, diese Membran zu wenig Elastizität hat, um nach Druckausgleich in die Betriebsstellung zurückzuspringen. To replace this rubber skin, a dermis is used in such cases, which but is less elastic like a rubber skin. It can then happen that, after the valve has worked and the pressure build-up causes the diaphragm to press against the seat has been pressed, this membrane has too little elasticity to compensate for pressure to jump back into the operating position.
Gemäß der Erfindung wird deshalb zwischen der Membran und der Dosenwand eine Feder, z. B. eine leichte Schraubenfeder, eingeführt, die nach Betätigung des Ventils den darauf eintretenden Druck ausgleicht, die Membran von dem Sitz abhebt und in die Normallage zurückführt.According to the invention is therefore between the membrane and the can wall Spring, e.g. B. a light coil spring introduced, the after actuation of the valve compensates for the pressure occurring thereupon, the membrane lifts off the seat and into the Normal position.
In der Zeichnung- ist beispielsweise eine Ausfü'hrungsform des Erfindungsgegenstandes im Schnitt dargestellt.The drawing shows, for example, an embodiment of the subject matter of the invention shown in section.
Der Sitz 1 ist an der den Auslaß tragenden Gehäusehälfte angeordnet. Die zwischen den Gehäusehälften eingeklemmte Membran 2 ruht bei Betätigung auf dem Sitz 1 und wird nach Betätigung von der Feder 3 in ihre Anfangsstellung zurückgeführt. >The seat 1 is arranged on the housing half carrying the outlet. The one between the Housing halves clamped membrane 2 rests on actuation on the seat 1 and is returned to its initial position after actuation of the spring 3. >
