Description

Die Erfindung bezieht sich auf ein Ventil zur Entnahme von fließfähigen Medien aus einem druckdichten Behälter mit Hilfe eines fluiden Treibmittels im Behälter nach dem Anspruch 1.The invention relates to a valve for the removal of flowable Media from a pressure-tight container using a fluid propellant in the container according to claim 1.

Ventile für sogenannte Treibmittelbehälter sind in den verschiedensten Varianten bekannt. Üblicherweise befindet sich das Treibmittel bereits im Druckbehälter, wobei es über das am Behälter angebrachte Ventil eingepreßt wird. Da die Strömungswege im Ventil relativ eng sind, ist auch bekannt, das Druckmittel beim Befüllen zwischen einer Dichtung, die das Ventilgehäuse gegenüber einem Dom des Ventiltellers abdichtet und dem Ventilteller strömen zu lassen. Für die Abgabe von z.B. Getränken aus größeren Behältern, beispielsweise mit einem Fassungsvermögen von über 2 Litern mit Hilfe eines gasförmigen Treibmittels ist aus DE 200 02 335 bekannt geworden, zwischen einem Ventilstem und einer im Dom des Ventiltellers angebrachten Ringdichtung wahlweise einen Durchgang zum Inneren des Behälters zu schaffen. Wird der Ventilstem durch Eindrücken betätigt, kann gasförmiges Medium seitlich am Stem vorbei in das Innere des Behälters strömen und dadurch das im Behälter befindliche Medium über die Bohrung im Stem austreiben.Valves for so-called propellant containers are in a wide variety of variants known. The propellant is usually already in the Pressure vessel, whereby it is pressed in via the valve attached to the vessel becomes. Since the flow paths in the valve are relatively narrow, it is also known that Pressure fluid when filling between a seal that the valve housing seals against a dome of the valve plate and flow to the valve plate allow. For the delivery of e.g. Drinks from larger containers, for example with a capacity of over 2 liters with the help of a Gaseous blowing agent has become known from DE 200 02 335, between one valve stem and one in the dome of the valve plate Ring seal optionally a passage to the inside of the container create. If the valve stem is actuated by pushing it in, gaseous Flow the medium past the stem into the inside of the container and thereby the medium in the container through the hole in the stem cast out.

Das im Behälter befindliche Treibmittel hat zum einen die Aufgabe, das Medium aus dem Druckbehälter auszutreiben und zum anderen das ausgetriebene Medium in gewünschter Weise zu verteilen, beispielsweise zu versprühen. Bei flüssigen Medien stellt dies kaum ein Problem dar. Sollen hingegen stärker viskose Medien versprüht werden, beispielsweise Gele oder Öle, stellen sich Schwierigkeiten ein. Es ist bekannt, ein auszutreibendes Medium in einem Druckbehälter in einem separaten Beutel aufzunehmen, der druckdicht mit der Ventilanordnung verschweißt ist. Das Medium aus dem Beutel wird über den im Behälter außerhalb des Beutels befindlichen Gasdruck ausgetrieben. Bei einer solchen Anordnung ist es besonders schwierig, ein viskoses Medium in gewünschter Weise zu versprühen.The blowing agent in the container has the task, on the one hand, of the medium to expel from the pressure vessel and secondly the expelled Distribute medium in the desired manner, for example spray. This is hardly a problem with liquid media more viscous media are sprayed, for example gels or oils, difficulties arise. It is known to be a medium to be driven out in a pressure container in a separate bag that is pressure-tight is welded to the valve assembly. The medium from the bag is expelled via the gas pressure in the container outside the bag. With such an arrangement, it is particularly difficult to obtain a viscous one Spray medium in the desired manner.

Häufig besteht auch das Problem, zwei im Behälter getrennt gespeicherte Medien gleichzeitig abzugeben, wobei sie im Abgabe- oder Sprühkopf vermischt werden. Hierbei handelt es sich um solche Medien, die beim Zusammentreffen miteinander reagieren, wie z. B. bei Haarfärbemitteln.Often there is also the problem of two stored separately in the container Dispense media simultaneously, mixing them in the dispenser or spray head become. These are media that come together react with each other, such as B. in hair dyes.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Ventil für die Entnahme von fließfähigen Medien aus einem druckdichten Behälter so zu gestalten, daß auch stärker viskose Medien versprüht oder zerstäubt werden können, oder daß eine gleichzeitige Entnahme von zwei Substanzen ermöglicht.The invention is therefore based on the object of a valve for removal to design flowable media from a pressure-tight container that even more viscous media are sprayed or atomized can, or that a simultaneous removal of two substances allows.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.

Bei dem erfindungsgemäßen Ventil weist der Ventilstem einen zum oberen Ende des Stems hin geöffneten Kanal auf, der über eine zweite Querbohrung mit der Außenseite des Stems verbunden ist. In der Schließstellung des Ventils bzw. des Stems ist die zweite Querbohrung von der ersten Dichtung abgesperrt, während in der Öffnungsstellung über die Querbohrung eine Verbindung zwischen dem Kanal im Stem und dem Inneren des Behälters hergestellt ist. Beim Öffnen des Ventils strömt nicht nur das Medium über die Bohrung im Stem nach außen zu einem entsprechenden Abgabe- oder Sprühkopf, sondern das Gas aus dem Behälter tritt in den Kanal im Stem und kann daher zusammen mit dem Medium ausgetragen werden. Dieses unter relativ hohem Druck stehende Gas reichert das Medium mit Gas an und unterstützt die gewünschte Sprühwirkung.In the valve according to the invention, the valve stem points to the upper one At the end of the stem open channel, which has a second cross hole is connected to the outside of the stem. In the closed position of the valve or the stem, the second transverse bore is blocked off by the first seal, while in the open position via the cross hole made between the channel in the stem and the inside of the container is. When the valve is opened, not only the medium flows over the Drilling in the stem to the outside to a corresponding delivery or Spray head, but the gas from the container enters the channel in the stem and can therefore be carried out together with the medium. This under relatively high pressure gas enriches and supports the medium with gas the desired spray effect.

Bei der Erfindung wird von der Tatsache ausgegangen, daß selbst bei Treibmitteln, die zunächst im Treibmittelbehälter im flüssigen Aggregatzustand vorliegen, im oberen Bereich des Behälterinneren sich eine Gasphase befindet, aus der heraus der Kanal im Stem gespeist wird, wenn das Ventil geöffnet wird.The invention is based on the fact that even with propellants, initially in the propellant container in the liquid state there is a gas phase in the upper area of the container, from which the stem is fed when the valve is open becomes.

Besonders vorteilhaft ist die Anwendung des erfindungsgemäßen Ventils für Treibmittelbehälter, bei denen das Medium in einem Beutel innerhalb des Behälters gespeichert ist.The use of the valve according to the invention is particularly advantageous for Propellant container, in which the medium in a bag inside the Container is stored.

Statt einer Unterstützung des Austreibens eines Mediums, kann das zweite unter Druck stehende Medium auch dafür verwendet werden, mit dem ersten in Reaktion gebracht zu werden, indem beide Medien im Sprühkopf zusammen kommen und dort vermischt werden. Dieses Verfahren kann z. B. bei Haarfärbemitteln eingesetzt werden. Hierbei ist jedoch notwendig, daß beide Medien im Behälter getrennt untergebracht sind. Um beide Medien auszutreiben, ist ein Treibmittel erforderlich, insbesondere ein Treibgas, das z. B. auf einen ein erstes Medium enthaltenden Beutel drückt sowie auf das Volumen des zweiten Mediums außerhalb des Beutels. In diesem Fall ist der Behälter über Kopf zu halten, damit das zweite Medium ausgetrieben werden kann. Instead of supporting the expulsion of one medium, the second pressurized medium can also be used with the first to be reacted by putting both media in the spray head together come and be mixed up there. This method can e.g. B. at Hair dyes are used. However, it is necessary that both Media are stored separately in the container. To drive out both media a blowing agent is required, in particular a propellant gas, the z. B. presses on a bag containing a first medium and on the volume the second medium outside the bag. In this case it is Keep container overhead so that the second medium can be expelled can.

The sealing ring 46 is supported downward over several in the circumferential direction equally spaced axially parallel ribs 48 of the housing 20 from. A coil spring 50 which is uniform in circumferential direction supports spaced axially parallel ribs 52 of section 28, acts against the underside of the stem 32 and tensions it upwards into the 1 shown in the closed position. An axial pin 52a protrudes the spring 50, which is guided on the outside by axially parallel ribs 54.

Wird der Stem 32, wie in Fig. 2 gezeigt, nach unten gedrückt gegen die Wirkung der Feder 50, liegen die Querbohrungen 36 frei, und das Medium innerhalb des nicht gezeigten Behälters kann entlang der Linie 56 zwischen den Rippen 32 und den Rippen 48 und über die Querbohrungen 36 und den Kanal 34 nach oben strömen und über einen Abgabekopf abgegeben werden. Gleichzeitig wird über die Querbohrung 35 ein Strömungsweg 60 in den Ringkanal 33 freigegeben. Die Querbohrung 35 ist in der Öffnungsstellung des Stems 32 mit dem Raum unterhalb des Ventiltellers 12 in Verbindung, so daß das Gas im oberen Bereich des nicht gezeigten Behälters über den Ringkanal 33 ausgetragen und zur Unterstützung der Ausbringung des Mediums herangezogen werden kann.As shown in FIG. 2, the stem 32 is pressed down against the action the spring 50, the cross bores 36 are exposed, and the medium within of the container, not shown, can be taken along line 56 between the ribs 32 and the ribs 48 and over the transverse bores 36 and Flow channel 34 upwards and be dispensed via a dispensing head. At the same time, a flow path 60 into the cross bore 35 Ring channel 33 released. The transverse bore 35 is in the open position the stem 32 with the space below the valve plate 12 in connection, so that the gas in the upper region of the container, not shown, via the ring channel 33 carried out and to support the application of the medium can be used.

Die Ausführungsform nach den Figuren 3 und 4 weist die gleiche Ventilanordnung auf wie die Ausführungsform nach den Figuren 1 und 2. Daher sind gleiche Teile mit gleichen Bezugszeichen wie in den Figuren 1 und 2 versehen. Der Unterschied zur Ausführungsform nach den Figuren 1 und 2 liegt darin, daß ein laminierter Beutel 62 am Abschnitt 28 des Gehäuses 20 dichtend angeschweißt ist. Im Beutel 62 befindet sich ein relativ viskoses Medium. Außerhalb des Beutels im nicht gezeigten Behälter befindet sich ein gasförmiges Treibmittel, mit dessen Hilfe der Inhalt des Beutels über den bereits zu Fig. 1 und 2 gezeigten Weg 56 und einen nicht gezeigten Abgabekopf ausgetragen werden kann. Bei der Betätigung des Ventils wird außerdem separat Gas parallel dem ausgebrachten Medium zugeführt, um den Austragvorgang zu beeinflussen.The embodiment according to Figures 3 and 4 has the same valve arrangement on like the embodiment of Figures 1 and 2. Therefore are the same parts with the same reference numerals as in Figures 1 and 2 Mistake. The difference from the embodiment according to FIGS. 1 and 2 lies in the fact that a laminated bag 62 is attached to section 28 of housing 20 is welded to seal. There is a relatively viscous one in the bag 62 Medium. Outside of the bag is in the container, not shown a gaseous propellant, with the help of which the contents of the pouch pass over the path 56 already shown in FIGS. 1 and 2 and a delivery head, not shown can be carried out. When the valve is actuated also gas is fed separately in parallel to the medium to be discharged To influence the discharge process.

Das separat zugeführte Gas kann mit dem anderen Medium auch zur Reaktion gebracht werden, um ein gemischtes Produkt zu erhalten, z. B. ein Haarfärbemittel.The separately supplied gas can also react with the other medium brought to obtain a mixed product, e.g. B. a hair dye.

Schließlich kann ein zweites Medium außerhalb des Beutels im Behälter über den gezeigten Weg mit Hilfe eines Treibmittels ausgetrieben werden, das zugleich einen Preßdruck auf den Beutel erzeugt. Um einen sicheren Austrieb des zweiten Mediums zu erzielen, ist geboten, den Behälter mit der Ventilanordnung über Kopf zu halten. Dadurch sammelt sich das zweite Medium im Ventilbereich des Behälters und das Treibmittel im Bodenbereich des Behälters. Es ist jedoch auch möglich, mit dem Ventil über die Öffnung 46a ein Steigrohr zu verbinden (nicht gezeigt), das nach unten in den Behälter geführt ist. Für diesen Fall ist eine Entnahme auch in Normalhaltung des Behälters möglich.Finally, a second medium can be placed outside the bag in the container can be driven out with the help of a propellant, which also creates a pressure on the bag. To be safe To achieve expulsion of the second medium, the container with the Keep valve assembly overhead. This collects the second medium in the valve area of the container and the propellant in the bottom area of the container. However, it is also possible to use the valve through the opening 46a to connect a riser pipe (not shown) that goes down into the Container is guided. In this case, removal is also normal of the container possible.
