Description

Die Erfindung betrifft eine Überdrucksicherung an Ventilen für Behälter, welche zur Aufnahme verflüssigter Gasse, wie Propan, Butan, Dimethyläther, Ammoniak u. a. m., bestimmt sind. Die Sicherung ist so ausgeführt, daß ihre Funktion mittels eines von außen einführbaren, mit dem Ventilkegel kuppelbaren Hilfsgerätes nachprüfbar ist.The invention relates to an overpressure protection device on valves for containers, which to absorb liquefied gas, such as propane, butane, dimethyl ether, ammonia i.a. m., are determined. The fuse is designed so that its function by means of an externally insertable auxiliary device that can be coupled to the valve cone can be checked is.

Gemäß der Erfindung trägt der Ventilkegel einen Fortsätz, der in einer abgedichteten Öffnung in der Abdeckung des Ventils geführt ist, wobei die Abdeckung aus einer gelochten Scheibe und einer daraufliegenden, biegsamen Gummidichtung besteht, die den Austritt des Gases oder der Flüssigkeit aus der Überdrucksicherung gestattet, aber das Eindringen von Feuchtigkeit u. dgl. von außen verhindert. Vorzugsweise ist der den Fortsatz des Ventilkörpers umgebende Rand der Gummidichtung abgeschrägt oder manschettenartig umgebogen.According to the invention, the valve cone carries a continuation in a sealed opening is guided in the cover of the valve, the cover consists of a perforated disc and a flexible rubber seal on top, which allows the gas or liquid to escape from the overpressure safety device, but prevents the penetration of moisture and the like from the outside. Preferably the edge of the rubber seal surrounding the extension of the valve body is beveled or bent like a cuff.

Das so eingerichtete Ventil ist gegen Staub, Nässe und Frost geschützt. Man kann es in Wasser eintauchen, wie dies zur Prüfung des mit dem Ventil versehenen Behälters auf vollkommene Dichte erforderlich und üblich ist, und trotzdem läßt es den Durchtritt des abblasenden Gases zu.The valve set up in this way is protected against dust, moisture and frost. It can be immersed in water, as is done to test the valve-fitted Container to perfect density is required and common, and still leaves it closes the passage of the venting gas.

Die Zeichnung veranschaulicht die Erfindung an einem Ventil für Propanflaschen in senkrechtem Durchschnitt, teilweise in Seitenansicht.The drawing illustrates the invention on a valve for propane bottles in vertical section, partly in side view.

Ein Fortsatz l des Ventilkegels a ist mittels einer gelochten Führungsscheibe m und durch eine eingelegte Gummischeibe n in der Verschlußkappe d geführt, um eine Abdichtung gegen das Eindringen von Staub und Nässe durch die Öffnung o der Verschlußkappe zu schaffen. Die Bohrung der Gummischeibe n ist nach innen zungenartig abgeschrägt, gegebenenfalls manschettenartig umgebogen, damit der Durchtritt des Gases oder der Flüssigkeit erleichtert und das Eindringen von Feuchtigkeit von außen her erschwert wird. Der Fortsatz l des Ventilkegels besitzt die Bohrung g zum Einschrauben eines als Hilfsgerät dienenden Stiftes. Wenn der Ventilkegel infolge Überdruckes im Behälter anspricht, so strömt die Flüssigkeit oder das Gas durch die Löcher der Scheibe m hindurch zwischen der Gummischeibe n und dem Kegelfortsatz l nach außen ab, wobei die Gummischeibe durchgebogen wird.An extension l of the valve cone a is guided in the cap d by means of a perforated guide disk m and through an inserted rubber disk n in order to create a seal against the ingress of dust and moisture through the opening o of the cap. The bore of the rubber washer n is beveled inwardly in the manner of a tongue, possibly bent over in the manner of a sleeve, so that the passage of the gas or the liquid is facilitated and the penetration of moisture from the outside is made more difficult. The extension l of the valve cone has the bore g for screwing in a pin serving as an auxiliary device. When the valve cone responds as a result of excess pressure in the container, the liquid or gas flows through the holes in the disk m between the rubber disk n and the conical extension l to the outside, the rubber disk being bent.

Beim Prüfen des Ventilkegels auf guten Sitz wird ein Stift mit Gewindezapfen in die Bohrung g des Kegels a eingeschraubt und die Anlüftekraft des Kegels mittels einer Federwaage gemessen. Nach beendeter Prüfung wird der Stift wieder ausgeschraubt und der dichte Abschluß des Ventils nochmals kontrolliert, z. B. mit Hilfe einer schaumbildenden Flüssigkeit.When checking the valve cone for a good fit, a pin with a threaded pin is used screwed into the hole g of the cone a and the lifting force of the cone by means of measured on a spring balance. After the test has ended, the pin is unscrewed again and the tight seal of the valve checked again, z. B. with the help of a foaming liquid.
