Abstract

Valve plate comprises a gas-tight sealing layer (6) arranged between plate layers (1, 2) in a peripheral partial region. Surface recesses of the plate layers are filled.

Description

Die vorliegende Erfindung betrifft einen Ventilteller gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a valve disk according to the preamble of Claim 1.

Ein derartiger Ventilteller ist aus der DE 33 17 809 A1 bekannt.Such a valve disk is known from DE 33 17 809 A1.

Solche Ventilteller, die einerseits einen Verschluß für ein Behältnis bilden und andererseits der Aufnahme eines Ventils dienen, werden an Behältnissen montiert, die mit einem unter Druck stehenden Medium befüllt sind.Such valve disk, on the one hand form a closure for a container and on the other to accommodate a valve, are mounted on containers, which are filled with a pressurized medium.

Insbesondere bei Befüllung mit einem Gas, beispielsweise zum Betrieb einer Camping-Kochstelle oder einer Löteinrichtung, ergeben sich beim Einsatz der Ventilteller Probleme, da die aneinander liegenden, zu einem Ventilteller geformten Zuschnittstücke nicht gasdicht miteinander verbunden sind.In particular, when filled with a gas, for example, to operate a camping stove or a soldering, arise when using the valve disc Problems, since the contiguous, to a valve plate shaped cut pieces not connected to each other gas-tight.

Durch die Oberflächenrauhigkeit sind zwischen den beiden Lagen Mikrozwischenräume vorhanden, durch die das unter Druck stehende Gas aus dem Inneren des Behältnisses entweichen kann. Due to the surface roughness, there are micro-spaces between the two layers through which the pressurized gas from inside the Can escape container.

Zwar ist die Menge des entweichenden Gases, bezogen auf eine Zeiteinheit, relativ gering, da jedoch ein Ausstrom ständig erfolgt, entweicht insgesamt gesehen über den gesamten Nutzungszeitraum des Behältnisses eine nicht unerhebliche Menge so daß das tatsächlich nutzbare Gasvolumen nur einen entsprechenden Anteil ausmacht.Although the amount of escaping gas, relative to a unit time, relative low, but as an outflow is constantly, escapes over altogether the entire period of use of the container a significant amount so that the actual usable gas volume makes up only a corresponding proportion.

Diesem Umstand kommt vor allem deshalb eine besondere Bedeutung zu, als die Behältnisse für den genannten Verwendungszweck in großen Stückzahlen zum Einsatz kommen, wodurch sich natürlich ein entsprechender wirtschaftlicher Schaden ergibt.This circumstance is therefore of particular importance, as the Containers for the stated purpose in large numbers for Use, which naturally causes a corresponding economic damage results.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Ventilteller der gattungsgemäßen Art so weiter zu entwickeln, daß ein ungewolltes Ausströmen von vorzugsweise Gas aus dem befüllten Behältnis ausgeschlossen ist.The present invention is therefore based on the object, a valve disc the generic type to develop so that an unwanted outflow is excluded from preferably gas from the filled container.

Diese Aufgabe wird durch einen Ventilteller gelöst, der die Merkmale des Anspruchs 1 aufweist.This object is achieved by a valve disk having the features of the claim 1 has.

Mit Hilfe der zwischen zwei Zwischenstücken vollflächig angeordneten Dichtungsschicht wird der vorhandene, durch die Oberflächenrauhigkeit gebildete Mikrozwischenraum so hermetisch verfüllt, daß das Durchströmen von Gasmolekülen ausgeschlossen ist.With the help of between two spacers over the entire surface arranged sealing layer becomes the existing micro-space formed by the surface roughness so hermetically filled that the passage of gas molecules is excluded.

Der neue Ventilteller besitzt insoweit Eigenschaften wie ein einstückiges Teil, ohne die insbesondere fertigungstechnischen Vorteile, die die Herstellung aus mehreren Lagen mit sich bringt, einzuschränken.The new valve plate has properties as a one-piece part, without the particular manufacturing advantages that the production of several Lifts brings with it, restrict.

Selbst über einen langen Zeitraum ist der neue Ventilteller so dicht, daß kein meßbarer Gasaustritt festzustellen ist.Even over a long period of time, the new valve disk is so dense that no measurable Gas leakage is observed.

Aus den in der Beschreibungseinleitung genannten Gründen ergibt sich eine ganze Reihe von Vorteilen durch die Erfindung, von denen insbesondere der wirtschaftliche Aspekt zu nennen ist, da das in das Behältnis eingebrachte Gasvolumen vollständig nutzbar ist.For the reasons mentioned in the introduction, there is a whole Series of advantages by the invention, of which in particular the economic Aspect is to call, since the gas volume introduced into the container completely is usable.

Als gasdichte Dichtungsschicht kann eine Folie vorgesehen sein, die auf einer Seite der beiden Zuschnittsstücke vor der Verformung aufgebracht ist.As a gas-tight sealing layer, a film may be provided which on one side the two blank pieces is applied before deformation.

Dabei ist nach einem weiteren Gedanken vorgesehen, als Kunststofffolie eine selbsthaftende einzusetzen, beispielsweise Polypropylen, mit der eine Blechtafel, aus der eine Lage der Zuschnittsstücke gefertigt wird, beschichtet ist.It is provided for a further thought, as a plastic film a use self-adhesive, for example polypropylene, with a metal sheet, from which one layer of the cut pieces is made, is coated.

Statt einer Kunststofffolie kann das Blech auch mit einer Gummierung beschichtet sein, wobei in beiden Fällen durch die Verformung bzw. die Verformungskräfte bei der Herstellung des Ventiltellers die jeweilige Dichtungsschicht praktisch in die vorhandenen Oberflächenvertiefungen einfließt.Instead of a plastic film, the sheet can also be coated with a rubber coating be in both cases by the deformation or the deformation forces at the production of the valve disk, the respective sealing layer practically in the existing surface depressions flows.

Ebenfalls denkbar ist die Dichtungsschicht in zunächst flüssiger Form aufzutragen, bspw. als Lack oder als geeigneter Kunststoff, die nach dem Auftrag aushärten und die Oberflächenvertiefungen ausfüllen. Zum Auftrag werden die zu einem Tellerdom gemeinsam verformten Tellerlagen in ein entsprechendes Tauchbad gegeben. Durch die Kapillarwirkung gelangt der flüssige Stoff in den Mikrozwischenraum und härtet danach aus. Voraussetzung ist eine entsprechend geringe Viskosität des Stoffes.It is likewise conceivable to apply the sealing layer in an initially liquid form, For example, as a paint or as a suitable plastic, which harden after the order and fill in the surface depressions. The order will be to a plate dome together deformed dish layers placed in a corresponding dip. Due to the capillary effect, the liquid substance enters the microinterspace and then harden. Prerequisite is a correspondingly low viscosity of Substance.

Die Lösung der Aufgabe der Erfindung entsprechend dem Anspruch 2 macht sich zunutze, daß grundsätzlich die aus Blech gebildeten, aufeinander liegenden Zuschnittsstücke verzinnt sind. Durch die Wärmeaufbringung zumindest im Bereich des Tellerdomes erfolgt eine Verschmelzung der Zinnschichten, wodurch ein gasdichter Verbund zwischen den Zuschnittsstücken hergestellt wird. In diesem Fall wird die Dichtungsschicht durch die im Sinne eines Schweißens miteinander verbundenen Zinnschichten gebildet.The solution of the object of the invention according to claim 2 makes itself exploit that in principle formed of sheet metal, superposed cut pieces tinned. By the heat application at least in the area the plate dome is a fusion of the tin layers, creating a gas-tight Composite is produced between the blanks. In this case the sealing layer is joined together by welding in the sense of welding Tin layers formed.

Eine Wärmebeaufschlagung des Ventiltellers zum Zwecke des Schmelzens der Zinnschichten reicht in einem Teilbereich des Ventiltellers aus, der sich jedoch über den vollen Umfang erstreckt, so daß eine hermetische Abdichtung in Ausströmrichtung des Gases gewährleistet ist.Heat application of the valve disk for the purpose of melting the Tin layers are sufficient in a partial area of the valve disk, which, however, is extends over the full circumference, so that a hermetic seal in the outflow direction the gas is guaranteed.

Im übrigen ist die Erfindung mit geringem fertigungstechnischen Aufwand zu realisieren, was insofern von Bedeutung ist, als solche Ventilteller in sehr großen Stückzahlen hergestellt werden.Moreover, the invention is to be realized with little manufacturing effort, What is significant in that, as such valve disk in very large Quantities are produced.

Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous embodiments of the invention are characterized in the subclaims.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der beigefügten Zeichnungen beschrieben.An embodiment of the invention will be described below with reference to the attached Drawings described.

Der in der Figur 1 gezeigte Ventilteller besteht insgesamt aus zwei Tellerlagen, und zwar aus einer inneren Tellerlage 1 sowie einer äußeren Tellerlage 2.The valve disk shown in Figure 1 consists of a total of two plate layers, and Although from an inner plate layer 1 and an outer plate layer. 2

Der Ventilteller ist durch gemeinsames Verformen von zwei Zuschnittsstücken gebildet, zwischen denen eine Dichtungsschicht 6 angeordnet ist.The valve disk is formed by jointly deforming two blank pieces, between which a sealing layer 6 is arranged.

Diese Dichtungsschicht 6 kann auf beiden Tellerlagen 1, 2 vorgesehen sein, wie dies beispielsweise beim Einsatz eines verzinnten Bleches der Fall ist.This sealing layer 6 may be provided on both plate layers 1, 2, as This is the case, for example, when using a tinned sheet.

Statt dessen kann die Dichtungsschicht 6 auch auf eine der beiden Tellerlagen 1, 2 aufgebracht sein, in jedem Fall aber auf der Seite einer Tellerlage 1, 2, die der anderen zugewandt ist. Instead, the sealing layer 6 on one of the two plate layers 1, 2 be applied, but in any case on the side of a plate layer 1, 2, the other is facing.

Eine solche Dichtungsschicht 6 ist beispielsweise als gasdichte Kunststoffolie oder als Gummierung aufgebracht, die nach der Verformung zu dem Ventilteller die vorhandenen Oberflächenvertiefungen der Tellerlagen 1, 2 im Berührungsbereich zumindest weitgehend ausfüllt.Such a sealing layer 6 is, for example, as a gas-tight plastic or applied as a rubber coating, which after deformation to the valve plate the existing surface depressions of the plate layers 1, 2 in the contact area at least largely fulfilled.

Bei Einsatz von verzinnten Blechen als Zuschnittsstücke reicht eine Erwärmung im oberen, also im Kopfbereich eines Tellerdomes 5, der ebenso angeformt ist wie ein umlaufender Kragen 3, durch den der Ventilteller mit einem nicht dargestellten Behältnis verbindbar ist.When using tinned sheets as blank pieces warming in the ranges upper, that is in the head area of a Tellerdomes 5, which is as well formed as a circumferential collar 3, through which the valve disc with a not shown Container is connectable.

Durch die Erwärmung im Kopfbereich des Tellerdomes 5, der sich ausgehend von einem radialen Tellerboden 4 axial erstreckt, wird ein Verschmelzen der beiden einander zugewandten Zinnschichten zu einer Dichtungsschicht erreicht, die sich über den gesamten Umfang des Tellerdomes 5 erstreckt. Auch hierdurch wird ein gasdichter Verbund der Tellerlagen 1, 2 erzielt.Due to the heating in the head region of the plate dome 5, starting from a radial plate bottom 4 extends axially, a fusion of the two facing each other tin layers to a sealing layer, which is extends over the entire circumference of the plate dome 5. This also becomes one gas-tight composite of the dish layers 1, 2 achieved.

Dieser Effekt wird durch das Ausfüllen vorhandener Oberflächenvertiefungen 7 der Tellerlagen 1, 2 erreicht, so daß kein Gas aus dem Inneren des Behältnisses passieren kann. This effect is achieved by filling in existing surface depressions 7 the dish layers 1, 2 reached, so that no gas from the inside of the container can happen.
