Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Gegenüber den bekannten Sicherheits-Ventilen, bei denen Membrandichtung verwendet wird und in der Regel eine Gegenfeder zur guten Function nöthig ist, zeigt die vorliegende Erfindung ein Sicherheits-Ventil für Carbidbehälter, bei welchem die Stahlmembran eingewalzte Sieken hat, welche auf einer elastischen Platte abdichten.Compared to the well-known safety valves in which a membrane seal is used and as a rule a counter spring is necessary for good function, shows the present invention a safety valve for carbide containers in which the steel membrane is rolled in Sieken has which seal on an elastic plate.

In beiliegender Zeichnung ist ein solches Membran-Sicherheits-Ventil dargestellt, welches nicht nur von gröfserer Stabilität ist, sondern auch eine absolute Abdichtung zwischen den Sieken und der elastischen Zwischenlage bewirkt.There is one in the accompanying drawing Membrane safety valve shown, which is not only of greater stability, but also causes an absolute seal between the sieves and the elastic intermediate layer.

Ein Stutzen g, nach innen oder aufsen durchgebaucht, ist an geeigneter Stelle des Carbidbehälters absolut dicht befestigt. Ueber Oeffnungen I des Stutzens g ist eine kapseiförmig gehaltene Membran m dicht befestigt. Ueber den Oeffnungen / des Stutzens ist ein Sieb s vorgesehen, welches das Mitreifsen von Carbidtheilchen verhindert. Die Membran m hat ein oder mehrere Sieken (Wulste) t, welche in normalem Zustande auf einer zwischen ihneri und dem Boden des Stutzens g bezw. dem Siebe s befindlichen elastischen Platte c abdichten. Bei eventuell im Innern des Gefäfses auftretendem Ueberdrucke wird die Membran m durchgedrückt, die Sieken if heben sich von der elastischen Platte c ab und der Ueberdruck kann durch die mittlere Oeffhung ν der Membran entweichen. Die Membran selbst kann zum Schütze gegen Zerstörung von aufsen mit einer Kapsel q, welche entsprechende Oeffnungen ο hat, abgedeckt werden.A connecting piece g, bulging inwards or outwards, is fastened absolutely tightly at a suitable point on the carbide container. A capsule-shaped membrane m is tightly fastened over openings I of the connection g. Over the openings / s of the sleeve is provided a screen which prevents the Mitreifsen of Carbidtheilchen. The membrane m has one or more Sieken (bulges) t, which in normal condition on a between him and the bottom of the nozzle g respectively. sealing the sieve s located elastic plate c. In the event of overpressure occurring inside the vessel, the membrane m is pressed through, the sieves if lift off from the elastic plate c and the overpressure can escape through the central opening ν of the membrane. To protect against destruction, the membrane itself can be covered from the outside with a capsule q which has appropriate openings o.

Claims (1)

Patent-Anspruch:Patent claim: Membran-Sicherheits-Ventil für Carbidbehälter, gekennzeichnet durch eine die Austrittsöffnungen des Behälters derart abdeckende Membran, dafs diese durch eingedrehte Sieken (Wulste) direct auf einer zwischengelegten elastischen Platte bei Minderdruck abdichtet, bei Ueberdruck jedoch sich abhebt und diesen durch die innerhalb der Sieken befindlichen Austrittsöffnungen entweichen läfst. Membrane safety valve for carbide containers, characterized by a membrane covering the outlet openings of the container in this way, that this by twisted sieves (bulges) directly on an interposed elastic Plate seals at low pressure, but lifts off at overpressure and this through allows the outlet openings located inside the sieves to escape.
