Description

Die Erfindung betrifft eine Ventilanordnung zur Abgabe von fluiden Medien, die in Behältnissen, insbesondere in Druckdosen, unter Druck gelagert sind, gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a valve arrangement for dispensing fluid media, which in Containers, especially in pressure cans, are stored under pressure, according to Preamble of claim 1.

In Gewerbe und Industrie, im Haushalt, und in vielen weiteren Anwendungsfällen kommen Druckdosen zum Einsatz, in denen fluide Medien unter Druck aufbewahrt sind. Bei den fluiden Medien kann es sich um Lacke, Schmiermittel, Reinigungsmittel, schäumende Medien und dergleichen mehr handeln. Die Druckdosen weisen üblicherweise eine längliche Form auf und besitzen eine offene Seite, die mittels einer Ventilanordnung verschlossen ist. Die Ventilanordnung umfasst einen Ventilteller, der mit dem Öffnungsrand der länglichen Druckdose verbunden ist und mit einem Austragventil für die fluiden Medien ausgestattet ist. Das Austragventil beinhaltet einen Ventilkörper, einen Ventilsitz mit Dichtungselement, ein Verschlussteil und ein Rückstellelement. Vielfach ist der Ventilteller topfartig ausgebildet und mit Anschlusseinrichtungen für einen Dosenadapter ausgestattet, der es erlaubt, die Druckdose fluiddicht mit einem händisch oder motorisch betätigbaren Austraggerät zu verbinden. Eine gattungsgemässe Ventilanordnung ist beispielsweise aus der EP-B-0 350 779 hinlänglich bekannt. Die bekannte Ventilanordnung ist insbesondere für Aerosoldosen aus Aluminium oder Blech ausgelegt. Diese Dosen besitzen eine genormte Öffnung, deren Durchmesser beispielsweise etwa 1 Zoll beträgt. Die Öffnung ist mit einem Rollrand ausgestattet, der zur Aufnahme des Ventiltellers dient. Nach dem Aufsetzen des Ventiltellers wird dieser durch Verformung formschlüssig mit der Dose verbunden. Dieser Vorgang wird üblicherweise als "clinchen" oder "crimpen" bezeichnet. In trade and industry, in the home, and in many other applications pressure cans are used in which fluid media are kept under pressure. The fluid media can be paints, lubricants, cleaning agents, act foaming media and the like. The sockets usually have elongated in shape and have an open side by means of a valve assembly is closed. The valve arrangement comprises a valve plate, which with the Opening edge of the elongated pressure cell is connected and with a discharge valve for the fluid media is equipped. The discharge valve includes a valve body, a Valve seat with sealing element, a closure part and a return element. Is multiple the valve plate is pot-shaped and with connection devices for a socket adapter equipped that allows the pressure can to be fluid-tight with a manual or to connect motor-operated discharge device. A generic valve arrangement is well known for example from EP-B-0 350 779. The well-known Valve arrangement is especially designed for aerosol cans made of aluminum or sheet metal. These cans have a standardized opening, the diameter of which is about Is 1 inch. The opening is equipped with a rolled edge, which can hold the Serves valve plates. After fitting the valve disc, it becomes deformed positively connected to the can. This process is commonly referred to as "clinching" or "crimping".

Der Ventilteller bildet das zentrale Teil dieser bekannten Ventilanordnungen und besteht aus Metall. Der metallene Ventilteller muss passgenau hergestellt werden und erfordert in der Serienfertigung teure Werkzeuge. Aus Dichtigkeitsgründen weisen die Ventile der bekannten Lösung gemäss der EP-B-0 350 779 einen Ventilsitz aus Kunststoff auf. Um dies zu ermöglichen, muss der metallische Ventilteller in eine Kunststoffspritzform eingelegt werden, in der er mit Kunststoff umspritzt wird. Abgesehen vom zusätzlichen Aufwand, den dieses Herstellverfahren bedeutet, kann zwischen dem metallischen Ventilteller und dem umspritzten Kunststoff ein Spalt verbleiben, durch den beispielsweise ein in der Druckdose befindliches Aerosol entweichen kann. Die Anschlusseinrichtungen für die Verbindung der Druckdose mit einem Austraggerät sind örtlich auf den zylindrischen Innenbereich des topfartigen Ventiltellers beschränkt und sind als Innengewinde ausgebildet. Die Werkzeuge zur Herstellung eines Innengewindes am Ventilteller sind relativ aufwendig und verteuern den Herstellungsprozess. Ausserdem weisen viele bekannte Austraggeräte standardisierte Anschlussteile auf, die auf die Durchmesser von Druckdosen mit Aussengewindeanschlüssen abgestimmt sind. Dadurch sind für die Anbindung der gattungsgemässen Druckdose an derartige Austragvorrichtungen vielfach separate Adapter nötig. Dies schlägt sich in zusätzlichen Kosten für die Herstellung und Beschaffung und in einem erhöhten Montageaufwand nieder.The valve disk forms the central part of these known valve arrangements and exists made of metal. The metal valve disc must be manufactured to fit and requires expensive tools in series production. For reasons of tightness, the valves of the known solution according to EP-B-0 350 779 a valve seat made of plastic. Around To make this possible, the metallic valve disc must be placed in a plastic injection mold in which it is encapsulated with plastic. Apart from the extra effort, which means this manufacturing process can between the metallic valve plate and the molded plastic remains a gap through which, for example aerosol in the pressure can can escape. The connection devices for the connection of the pressure cell with a discharge device are local on the cylindrical Limited interior of the pot-like valve plate and are designed as an internal thread. The tools for creating an internal thread on the valve disk are relative complex and make the manufacturing process more expensive. In addition, many known Discharge devices standardized connection parts based on the diameter of pressure sockets are coordinated with external thread connections. This is for the connection the generic pressure cell on such discharge devices often separate Adapter required. This translates into additional manufacturing and procurement costs and in an increased assembly effort.

Aufgabe der vorliegenden Erfindung ist es daher, eine gattungsgemässe Ventilanordnung für eine Druckdose dahingehend zu verändern, dass den zuvor geschilderten Nachteilen abgeholfen ist. Es soll eine Ventilanordnung geschaffen werden, bei der die Gefahr von Leckagen verhindert ist. Der Herstell- und Montageaufwand für die Ventilanordnung soll reduziert sein. Auf separate Adapterteile soll verzichtet werden können.The object of the present invention is therefore a generic valve arrangement to change for a pressure cell in such a way that the disadvantages described above is remedied. A valve arrangement is to be created in which the risk of Leakage is prevented. The manufacturing and assembly effort for the valve assembly should be reduced. There should be no need for separate adapter parts.

Die Lösung dieser Aufgaben besteht in einer Ventilanordnung zur Abgabe von fluiden Medien, die in Behältnissen, insbesondere in Druckdosen, unter Druck gelagert sind, mit den im kennzeichnenden Abschnitt des Patentanspruchs 1 angeführten Merkmalen. Bevorzugte Ausführungsvarianten und/oder Weiterbildungen der Erfindung sind Gegenstand der abhängigen Patentansprüche. Die Erfindung betrifft eine Ventilanordnung zur Abgabe von fluiden Medien, die in zylindrischen Behältnissen, insbesondere in Druckdosen, unter Druck gelagert sind, umfasst einen topfförmig ausgebildeten Ventilteller, der mit der offenen Seite der Druckdose verbindbar ist und eine Kupplungseinrichtung für einen Dosenadapter eines Austraggerätes aufweist. Der Ventilteller ist mit einem Austragventil ausgestattet, das einen Ventilkolben und ein Rückstellelement umfasst. Erfindungsgemäss besteht der topfförmige Ventilteller aus Kunststoff und weist eine plastisch verformbare, insbesondere clinchbare, zylindrische Topfwandung auf. Die Kupplungseinrichtung ist ein integrales Anschlussteil, vorzugsweise ein zylindrischer Aussengewindering, aus Kunststoff, das über dünne Verbindungsstege mit dem äusseren Umfangsrand der Topfwandung des Ventiltellers verbunden ist.The solution to these problems consists in a valve arrangement for dispensing fluids Media that are stored in containers, especially in pressure cans, under pressure the features stated in the characterizing section of claim 1. Preferred embodiments and / or developments of the invention are the subject of the dependent claims. The invention relates to a valve arrangement for Dispensing of fluid media in cylindrical containers, especially in pressure cans, are stored under pressure, includes a cup-shaped valve plate, the is connectable to the open side of the pressure cell and a coupling device for has a can adapter of a discharge device. The valve plate is with a discharge valve equipped, which includes a valve piston and a return element. According to the invention, the cup-shaped valve disk is made of plastic and has one plastically deformable, in particular clinchable, cylindrical pot wall. The Coupling device is an integral connecting part, preferably a cylindrical one External threaded ring, made of plastic, which is connected to the outside via thin connecting webs Peripheral edge of the pot wall of the valve plate is connected.

Indem der topfförmige Ventilteller gesamthaft als Kunststoffteil ausgebildet ist, entfällt das bei den aus dem Stand der Technik bekannten Ventiltellern aus Dichtigkeitsgründen und für den Korrosionsschutz erforderliche, nachträgliche Umspritzen des Ventiltellers mit Kunststoff. Dadurch werden Spalte, die zwischen dem metallischen Ventilteller und dem umspritzten Kunststoff auftreten und Undichtigkeiten der Druckdose verursachen können, vermieden. Das in die Druckdose eingefüllte Medium kommt nur mit dem Kunststoffventilteller in Kontakt. Der Kunststoffventilteller erfüllt gleichzeitig die Abdichtfunktion. Der Ventilteller aus Kunststoff ist einfach und kostengünstig in der Herstellung und in der Montage. Die für die Montage an einem manuellen bzw. motorisch betätigbaren Austraggerät erforderliche Kupplungseinrichtung ist integral mit dem Ventilteller ausgebildet. Dies erleichtert die Herstellung des Ventiltellers und des Anschlussteils in einem Arbeitsschritt. Die dünnen Verbindungsstege, über die das Anschlussteil mit dem Ventilteller aus Kunststoff verbunden ist, verhindern die Übertragung eines unzulässig grossen Dreh- oder Kippmoments auf den Ventilteller. Das Anschlussteil kann beispielsweise Teil eines Bajonettverschlusses sein. Aus fertigungstechnischen Gründen ist es bevorzugt als ein zylindrischer Aussengewindering ausgebildet. Die dünnen Verbindungsstege brechen, bevor der mit dem Öffnungsrand der Druckdose verclinchte Ventilteller gegenüber der Druckdose verdreht oder durch Verkippen abgehoben werden kann. Das von den dünnen Verbindungsstegen gerade noch übertragbare Solldrehmoment beträgt etwa 5 Nm. Bei grösseren Drehmomenten kommt es zu einem Bruch der Verbindungsstege. Für die Festigkeit gegenüber Verkippen gelten für die Verbindungsstege etwa die gleichen Festigkeiten. Dadurch ist zuverlässig verhindert, dass die Druckdose durch Fehlmanipulationen geöffnet und der Anwender mit dem unter Druck in der Druckdose gelagerten Inhalt in Kontakt kommen kann.This is eliminated by designing the cup-shaped valve disk as a plastic part in the valve plates known from the prior art for reasons of tightness and subsequent overmolding of the valve disc required for corrosion protection Plastic. This will create gaps between the metallic valve disc and the molded plastic can occur and cause leaks in the pressure cell, avoided. The medium filled into the pressure can only comes with the plastic valve disc in contact. The plastic valve disc also fulfills the sealing function. The Valve plate made of plastic is simple and inexpensive to manufacture and in Assembly. The for mounting on a manual or motorized discharge device required coupling device is integrally formed with the valve plate. This facilitates the manufacture of the valve plate and the connecting part in one Work step. The thin connecting webs, over which the connecting part with the Valve plate is connected from plastic, prevent the transfer of an impermissible large torque or tilting moment on the valve plate. The connector can for example, be part of a bayonet catch. For technical reasons it is preferably designed as a cylindrical external threaded ring. The thin ones Break the connecting webs before they connect to the opening edge of the pressure cell Valve disc rotated relative to the pressure cell or lifted off by tilting it can. That which can just be transferred by the thin connecting bars The target torque is approximately 5 Nm. At higher torques there is a Breakage of the connecting webs. For the strength against tilting apply to the Connecting webs about the same strength. This reliably prevents that the pressure cell is opened by incorrect manipulation and the user with the under Pressure stored in the pressure cell can come into contact.

Die Verbindungsstege des Anschlussteils mit dem Ventilteller sind mit Vorteil mit Sollbruchstellen ausgestattet. Dadurch ist sichergestellt, dass auch bei fertigungstechnisch bedingten Toleranzen in den Wandstärken der Stege die zulässigen Dreh- und Kippmomente nicht überschritten werden.The connecting webs of the connecting part with the valve disk are advantageous with Predetermined breaking points. This ensures that even in manufacturing technology conditional tolerances in the wall thicknesses of the webs the permissible turning and Tilting moments are not exceeded.

Um eine zuverlässige Dichtigkeit der Verbindung des Ventiltellers und des Öffnungsrands der Druckdose zu gewährleisten, wird der Ventilteller beim Verclinchen stark verformt. To ensure reliable sealing of the connection between the valve disc and the opening edge to ensure the pressure cell, the valve disk is strongly deformed when clinching.

Dabei erweisen sich Wandstärken des Ventiltellers im Bereich der plastisch verformbaren Topfwandung von etwa 0,2 mm bis etwa 1,0 mm, vorzugsweise 0,3 mm bis 0,8 mm, als zweckmässig. Bei diesen Wandstärken ist, je nach Art des verwendeten Kunststoffes, eine ausreichende Eigensteifigkeit des Ventiltellers gewährleistet, und die für den Verformungsvorgang bei der Verbindung mit dem Öffnungsrand erforderlichen Kräfte können ohne weitere Modifikationen von den bekannten Geräten aufgebracht werden.Here, wall thicknesses of the valve plate in the area of the plastically deformable are proven Pot wall from about 0.2 mm to about 1.0 mm, preferably 0.3 mm to 0.8 mm, as expedient. With these wall thicknesses, depending on the type of plastic used, a sufficient inherent rigidity of the valve plate is guaranteed, and that for the deformation process forces required when connecting to the opening edge can be applied without further modifications from the known devices.

Die erfindungsgemässe Ausbildung des Ventiltellers mit integralem Anschlussteil, insbesondere einem Aussengewindering, ermöglicht auch den Einsatz kostengünstiger Fertigungsverfahren. Vorzugsweise wird dabei auf die bekannten Spritzgiessverfahren zurückgegriffen, die eine einfache und schnelle Herstellung grosser Mengen der benötigten Teile ermöglichen.The inventive design of the valve plate with an integral connecting part, in particular an external threaded ring, also enables the use to be made more economically Manufacturing process. The known injection molding process is preferred resorted to the simple and quick production of large quantities of allow necessary parts.

Zur weiteren Erhöhung der Dichtigkeit der Verbindung des Kunststoffventiltellers mit dem Öffnungsrand der Druckdose ist in einer vorteilhaften Variante der Erfindung eine zusätzliche Nebenabdichtung vorgesehen.
