Description

Die Erfindung betrifft eine neuartige Verbindung zwischen einer Metallmembran und dem zugehörigen Gehäuse, insbesondere bei Druckminderventilen für Hochdruckgase. Bekannt sind zu gleichem Zweck durch Löten hergestellte Befestigungen, wozu sich aber nicht jedes Membran- und Gehäusemetall eignet und wobei als fester Anhalt nur die anhaftende unsichere Lötmasse zur GeltungThe invention relates to a novel connection between a metal membrane and the associated housing, especially in the case of pressure reducing valves for high pressure gases. Fastenings made by soldering are known for the same purpose, but what is the purpose not every membrane and housing metal is suitable and only the adhering unsafe soldering compound comes into its own

ίο kommt. Bei vorliegender Ausführung kann dagegen jede Art Membran- und Gehäusemetall unter voller. Ausnutzung der Membranquerschnittsfestigkeit Verwendung finden.ίο comes. In the present version can on the other hand, any kind of membrane and housing metal under full. Exploitation of the Find membrane cross-sectional strength use.

Die Bauart ist auf der. Zeichnung im Querschnitt dargestellt.The design is on the. Drawing shown in cross section.

Das durch die Hochdruekzuleitung b kommende Gas strömt über dem Ventil c druckvermindert in das Gehäuse a, dessen Flansch d an dem Flansch / des Gehäuseteils e befestigt ist. Zwischen den Flanschen d und / befindet sich als druckregelndes Organ die elastische Membran g aus beliebigem Metall, deren außen umgebogener Rand h nach innen zu anliegend .in eine unterstochene Nute j eines der beiden Flanschen d oder / oder auch an einer anderen Stelle des Gehäuses eingelassen und ringsum mit einem geeignetem Metallstoff, z. B. Blei, dicht und fest umgössen eingewalzt oder Terstemmt ist, so daß zwischen Membran und Gehäuse eine starre ,Verbindung hergestellt wird.The gas coming through the high pressure supply line b flows through the valve c at reduced pressure into the housing a, the flange d of which is attached to the flange / the housing part e . The elastic membrane g made of any metal is located between the flanges d and / as a pressure-regulating element, the edge h of which is bent outwards inwards and is embedded in an undercut groove j of one of the two flanges d or / or at another point in the housing and all around with a suitable metal material, e.g. B. lead, tightly and firmly poured in or rolled in, so that a rigid connection is made between the membrane and the housing.

Statt die Nut i nach außen zu unterstechen, kann deren äußere Seitenfläche auch mit Rillen zum Eindringen des Befestigungsstoffes gegen dessen Herausfallen versehen werden.Instead of puncturing the groove i to the outside, its outer side surface can also be provided with grooves for the penetration of the fastening material to prevent it from falling out.

Solche Befestigungen der Metallmembranen können auch zur Vermeidung von Stopfbüchsen bei Ventilen anderer Art erfolgen.Such fastenings of the metal diaphragms can also be used to avoid stuffing boxes for valves of a different type.
