Description
Die Erfindung bezieht sich auf ein Ventil zur Entnahme von fließfähigen Medien aus einem druckdichten Behälter mit Hilfe eines fluiden Treibmittels im Behälter.The invention relates to a valve for removing flowable Media from a pressure-tight container by means of a fluid propellant in the container.
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 variety of variants known. Usually, the blowing agent is already in Pressure vessel, whereby it presses on the valve attached to the container becomes. Since the flow paths in the valve are relatively narrow, it is also known that Pressure medium when filling between a seal, the valve housing seals against a dome of the valve disk and flow to the valve disk 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 propellant is known from DE 200 02 335, between a Ventilstem and one mounted in the dome of the valve disc Ring seal optionally a passage to the interior of the container too create. If the valve stem is pressed in, gaseous Flow the medium past the stem into the interior of the container and thereby the medium in the container via the bore 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 propellant in the container has on the one hand the task of the medium expelled from the pressure vessel and on the other the expelled Distribute medium in the desired manner, for example to spray. For liquid media, this is hardly a problem dar sprayed more viscous media, such as gels or oils, difficulties arise. It is known to be a medium to be expelled in a pressure vessel in a separate bag, the pressure-tight is welded to the valve assembly. The medium from the bag is expelled above the gas pressure in the container outside the bag. With such an arrangement, it is particularly difficult to be viscous To 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, two stored separately in the container Dispensing media simultaneously, mixing in the dispensing or spray head become. These are such media that meet at the meeting react with each other, such as B. in hair dyes.
Aus GB-A- 2 012 885 ist ein Ventil zur Entnahme von fließfähigen Medien
aus einem druckdichten Behälter mit Hilfe eines Treibmittels im Behälter
bekannt. Das Ventil besitzt einen Dom und einen den Dom umgebenden
Ventilteller mit Flansch, einen hohlen Ventilstem, der durch eine mittige
Öffnung im Dom in das Gehäuse geführt ist und an seinem vom Dom
fortweisenden Ende eine Querbohrung besitzt, in die das Medium eintreten
kann. Der Stem weist einen zweiten achsparallel zum oberen Ende des Stems
hin geöffneten Kanal auf, der über eine zweite Querbohrung 26 mit der
Außenseite des Stems verbunden ist und die zweite Querbohrung 26 in der
Schließstellung durch die erste Dichtung 7 gesperrt ist und in der
Öffnungsstellung über eine Öffnung im Gehäuse mit dem Inneren des
Behälters in Verbindung steht.From GB-A-2 012 885 there is a valve for the removal of flowable media
from a pressure-tight container by means of a propellant in the container
known. The valve has a dome and surrounding the cathedral
Valve disc with flange, a hollow Ventilstem, by a central
Opening in the dome is led into the housing and at its from the dome
endwise end has a transverse bore into which the medium enter
can. The stem has a second axis parallel to the top of the stem
towards open channel, which has a second
Aus DE 200 02 335 U1 ist ein Ventil zur Entnahme von flüssigen Medien aus einem druckdichten Behälter bekannt. Der Stem des bekannten Ventils besitzt einen zylindrischen Abschnitt, der innerhalb einer Distanzhülse geführt ist, die wiederum in dem Gehäuse gehalten ist. Die bekannte Distanzhülse besitzt axiale Rippen, die am oberen Ende in radiale Rippen übergehen. Über die Rippen ist die Distanzhülse an dem Dichtring abgestützt und seitlich durch den Abschnitt des Gehäuses festgelegt.From DE 200 02 335 U1 is a valve for the removal of liquid media known from a pressure-tight container. The stem of the known valve has a cylindrical section that is inside a spacer sleeve is guided, which in turn is held in the housing. The well-known Spacer sleeve has axial ribs at the top in radial ribs pass. About the ribs, the spacer sleeve is supported on the sealing ring and laterally defined by the portion of the housing.
Der Erfindung liegt die Aufgabe zugrunde, ein verbessertes Zweiwege-Ventil bereitzustellen, das insbesondere zum Austragen von zwei miteinander reagierenden Medien geeignet ist.The invention is based on the object, an improved two-way valve to provide, in particular for discharging two with each other Reactive media is suitable.
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 Ventilstem one to the top Open channel at the end of the stem, which has a second transverse bore connected to the outside of the stem. In the closed position of the valve or of the stem, the second transverse bore is shut off from the first seal, while in the open position on the transverse bore a connection made between the channel in the stem and the inside of the container is. When opening the valve not only the medium flows over the Bore in Stem outward to a corresponding dispensing 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 the medium with gas and supports the desired spraying 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, the first in the propellant container in the liquid state present, in the upper part of the container interior is a gas phase, out of which the channel in the stem is fed when the valve is opened becomes.
Besonders vorteilhaft ist die Anwendung des erfindungsgemäßen Ventils für Treibmittelbehälter, bei denen das Medium in einem Beutel innerhalb des Behälters gespeichert ist.Particularly advantageous is the application of the valve according to the invention Propellant container in which the medium in a bag within the Container is stored.
Das zweite unter Druck stehende Medium wird auch dafür verwendet, um 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. The second pressurized medium is also used to to be reacted with the first by both media in the Spray head come together and mixed there. This method can z. B. be used in hair dyes. Here is, however necessary that both media are housed separately in the container. Around expelling both media, a propellant is required, in particular a Propellant gas, the z. B. presses on a first medium containing bag as well as the volume of the second medium outside the bag. In In this case, keep the container upside down so that the second medium can be expelled.

is that a
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 be brought to obtain a mixed product, for. 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 may be outside the bag in the container
be expelled over the path shown using a propellant,
which also creates a pressing pressure on the bag. To be sure
To achieve spillage of the second medium, it is necessary to the container with the
Valve arrangement to keep upside down. As a result, the second medium collects
in the valve area of the container and the propellant in the bottom area
of the container. However, it is also possible with the valve over the
