Abstract

The valve includes a valve body formed onto a lid of a container, a closure member which is located in the valve body and a spiral spring which presses the closure member into the valve body so as to keep the valve closed. A first sealing section is formed on a section of the closure member and cooperates with a valve seat in the valve body. A second sealing section is formed on the valve body and cooperates with a part of a spray gun or similar device, into which the valve body section is inserted in order to prevent a leaking or fluid at that point. The valve does not need any sealing members made of elastomeric materials or rubber. In this way, deterioration of such sealing members, which is caused by the fluid and leads to loss of sealing capability, is avoided. Containers which are equipped with such valves can be stored in any arbitrary position.

Description

Die vorliegende Erfindung betrifft ein Ventil nach dem Oberbegriff nach Patentanspruch 1.The present invention relates to a valve according to the preamble of claim 1.

Derartige Ventile sind bekannt und werden von dem Behälter getragen. Der Behälter besitzt einen Dek­kel. Dieser aus Blech gestanzte Deckel ist mit einem zentralen Vorsprung ausgebildet, der eine koaxiale Oeff­nung bestimmt.Such valves are known and are carried by the container. The container has a lid. This lid, stamped from sheet metal, is formed with a central projection which defines a coaxial opening.

Das Ventil hat einen Ventilkörper, der mit dem Vorsprung verbunden ist, einen Verschlussteil, der im Ventilkörper verschiebbar angeordnet und von der Deckel­vorderseite her betätigbar ist, ein Dichtungsorgan, das zwischen Ventilkörper und Verschlussteil angeordnet ist, und ein Federelement, das den Verschlussteil gegen das Dichtungsorgan drückt.The valve has a valve body which is connected to the projection, a closure part which is arranged displaceably in the valve body and can be actuated from the front of the cover, a sealing element which is arranged between the valve body and the closure part, and a spring element which connects the closure part against the sealing element presses.

Das Dichtungsorgan besteht aus elastomerem Material oder Gummi und kommt mit dem durchströmenden Fluid in Berührung. Da diese Materialien nicht für alle Fluid beständig sind, kann das Ventil undicht werden.The sealing member is made of elastomeric material or rubber and comes into contact with the fluid flowing through. As these materials are not resistant to all fluids, the valve can leak.

Die der Erfindung zugrundeliegende Aufgabe besteht darin, ein Ventil zu schaffen, das ohne derarti­ge Dichtungsorgane auskommt und deren Dichtungsbereich für das durchströmende Fluid beständig ist.The object on which the invention is based is to provide a valve which does not require such sealing members and whose sealing area is resistant to the fluid flowing through.

Diese Aufgabe wird erfindungsgemäss mit den kennzeichnenden Merkmalen des Patentanspruches 1 gelöst.This object is achieved according to the invention with the characterizing features of patent claim 1.

Die mit der Erfindung erzielbaren Vorteile sind im wesentlichen darin zu sehen, dass Behälter mit unterschiedlichen Fluids z.B. Treibgas und Polyurethan in jeder beliebigen Lage gelagert werden können, ohne die Dichtheit zu vermindern und dass das Ventil ein Minimum an Einzelteile hat.The advantages achievable with the invention are essentially to be seen in the fact that containers with different fluids, for example propellant gas and polyurethane, can be stored in any position without reducing the tightness and that the valve has a minimum of individual parts.

Es ist insbesondere von Vorteil, wenn der Ver­schlussteil im wesentlichen zylinderförmig ausgebildet ist und wenn der Dichtungsabschnitt mindestens einen scheibenförmigen Abschnitt aufweist, der im wesentlichen radial vom Verschlussteil absteht. Durch die bei ge­schlossenem Ventil auftretende Verformung der scheiben­förmigen Dichtungsabschnitte kann eine sichere Dichtheit gewährleistet werden.It is particularly advantageous if the closure part is essentially cylindrical and if the sealing section has at least one disk-shaped section which projects essentially radially from the closure part. Due to the deformation of the disk-shaped sealing sections that occurs when the valve is closed, a secure tightness can be ensured.

Durch die Anwendung von zwei Dichtungsab­schnitten kann die Dichtheit weiter verbessert werden.The tightness can be further improved by using two sealing sections.

Bei der Benutzung derartiger Ventile mit bei­spielsweise einer Spritzeinrichtung ist es vorteilhaft, wenn der Ansatz im wesentlichen zylinderförmig ausgebil­det ist, und wenn der Ansatz einen Dichtungsabschnitt aufweist, der mindestens einen scheibenförmigen Ab­schnitt umfasst, wobei der Abschnitt im wesentlichen radial vom Ansatz absteht, um das Ventil beim Einsetzen abzudichten.When using such valves with, for example, a spray device, it is advantageous if the extension is essentially cylindrical and if the extension has a sealing section which comprises at least one disk-shaped section, the section projecting essentially radially from the extension around the valve to seal when inserting.

Mit dieser zusätzlichen Abdichtung kann der Austritt von Fluid ausserhalb des Ventiles verhindert werden.With this additional seal, the escape of fluid outside the valve can be prevented.

Bei einer bevorzugten Ausführungsform ist der Kunststoffteil an einen im wesentlichen umförmig ausge­bildeten zweiten Abschnitt des Behälterdeckels angeformt, und der U-förmige Abschnitt weist einen Randabschnitt auf, der einstückig am innenliegenden Schenkel des Abschnittes ausgebildet ist und sich im wesentlichen parallel zur Basis des Abschnittes nach Innen erstreckt, wobei dieser Randabschnitt von dem Kunststoffteiles um­schlossen ist, um das Ventil gasdicht abzudichten.In a preferred embodiment, the plastic part is molded onto an essentially circumferentially shaped second section of the container lid, and the U-shaped section has an edge section which is formed in one piece on the inner leg of the section and is essentially parallel to the base of the section and faces inwards extends, this edge section being enclosed by the plastic part in order to seal the valve in a gas-tight manner.

Mit dieser Massnahme kann die Dichtheit eines mit dem erfindungsgemässen Ventil versehenen Behälters erhöht werden.With this measure, the tightness of a container provided with the valve according to the invention can be increased.

Im folgenden wird die Erfindung anhand der beiliegenden Zeichnung erläutert, die Teilschnitte durch ein Ausführungsbeispiel des erfindungsgemässen Ventils im geschlossenen Zustand (rechter Teilschnitt) und im offenen Zustand (linker Teilschnitt) zeigt.The invention is explained below with reference to the accompanying drawing, which shows partial sections through an exemplary embodiment of the valve according to the invention in the closed state (right partial section) and in the open state (left partial section).

Das Ventil umfasst einen Ventilkörper 1, der an der Innenseite eines Behälterdeckels 2 angeformt ist, einen Verschlussteil 3, der im Ventilkörper 1 angeordnet ist, einen Haltetile 4, der am Ventilkörper 1 befestigt ist und eine Schraubenfeder 5, die zwischen dem Ver­schlussteil und dem Halteteil eingesetzt ist.The valve comprises a valve body 1 which is integrally formed on the inside of a container lid 2, a closure part 3 which is arranged in the valve body 1, a holding part 4 which is fastened to the valve body 1 and a coil spring 5 which is located between the closing part and the holding part is used.

Wie die Figur zeigt, stellt der Behälterdeckel 2 einen Hohlzylinder dar, der an einer Stirnseite einen vorgebördelten Abschnitt 6 zum Anschluss an einen Behäl­terrand und in vorteilhafter Weise an der anderen Stirn­seite einen im wesentlichen U-förmig ausgebildeten zwei­ten Abschnitt 7 aufweist, an den der Ventilkörper 1 an­geformt ist. Der U-förmig ausgebildete Abschnitt 7 weist an seinem innenliegenden Schenkel einen Randab­schnitt 23 auf, der einstückig mit dem Abschnitt 7 ausgebildet ist und sich im wesentlichen parallel zur Basis des Abschnittes 7 nach innen erstreckt. Der Be­hälterdeckel 2 ist ein Stanzteil und weist eine zentrale Oeffnung auf. Der Ventilkörper 1 weist einen Abschnitt 8, der von der Innenseite des Behälterdeckels 2 absteht und den Einlass bildet, und einen Ansatz 9 auf, der sich durch die Oeffnung in Richtung der Aussenseite des Be­hälterdeckels 2 erstreckt und den Auslass bildet. Der Ventilkörper 1 umschliesst den Randabschnitt 23, so dass in besonders vorteilhafter Weise eine gasdichte Dich­tung erzielt wird.As the figure shows, the container lid 2 is a hollow cylinder which has a pre-flanged section 6 on one end for connection to a container edge and advantageously on the other end a substantially U-shaped second section 7 to which the valve body 1 is molded. The U-shaped section 7 has on its inner leg an edge section 23 which is formed in one piece with the section 7 and extends essentially parallel to the base of the section 7 inwards. The container lid 2 is a stamped part and has a central opening. The valve body 1 has a section 8 which protrudes from the inside of the container lid 2 and forms the inlet, and a projection 9 which extends through the opening in the direction of the outside of the container lid 2 and forms the outlet. The valve body 1 encloses the edge section 23, so that a gas-tight seal is achieved in a particularly advantageous manner.

Der Ventilkörper 1 hat ferner eine Durchgangs­ bohrung 10, die sich ausgehend vom Auslass bis zu einem Abschnitt 11 mit dem Ventilsitz erstreckt, wobei die Sitzfläche als von der Durchgangsbohrung ausgehende Schrägfläche ausgebildet ist.The valve body 1 also has a passage bore 10, which extends from the outlet to a section 11 with the valve seat, the seat surface being designed as an inclined surface starting from the through bore.

Der Verschlussteil 3 hat einen zylinderförmi­gen Körper mit einem Flansch 13 an einem Ende, einen Dichtungsabschnitt 14, der angrenzend an den Flansch 13 ausgebildet ist, und vier Rillen 15, die sich ausgehend vom Dichtungsabschnitt 15 bis zum anderen Ende des Kör­pers erstrecken. Die Rillen 15 sind halbrund.The closure part 3 has a cylindrical body with a flange 13 at one end, a sealing section 14 which is formed adjacent to the flange 13, and four grooves 15 which extend from the sealing section 15 to the other end of the body. The grooves 15 are semicircular.

Der erfindungsgemässe Dichtungsabschnitt 14 wird durch zwei scheibenförmige Abschnitte 16, die radial vom Körper abstehen und einem Ansatz 17 gebil­det, der unmittelbar an den Flansch 13 angrenzt.The sealing section 14 according to the invention is formed by two disk-shaped sections 16 which protrude radially from the body and an extension 17 which is directly adjacent to the flange 13.

Der Halteteil 4 ist als Kappe ausgebildet, die auf den Ansatz 8 aufsetzbar ist. Hierzu ist die Kappe am Rand mit einem Bund 18 und der Ansatz 8 mit einer Rille versehen, in die der Bund eingreift. Im Bodenteil 19 der Kappe sind eine Anzahl von Löchern 20 vorgesehen. Ferner ist an der Innenseite der Kappe eine Ausnehmung 21 vorgesehen, in der die Feder 5 zentriert ist.The holding part 4 is designed as a cap which can be placed on the extension 8. For this purpose, the cap is provided on the edge with a collar 18 and the neck 8 with a groove in which the collar engages. A number of holes 20 are provided in the bottom part 19 of the cap. Furthermore, a recess 21 is provided on the inside of the cap, in which the spring 5 is centered.

Andererseits wird die Feder 5 an einem Ansatz 22 des Verschlussteiles 3 gehalten.On the other hand, the spring 5 is held on a shoulder 22 of the closure part 3.

Neben dem Dichtungsabschnitt 14 am Verschluss­teil 3 hat das Ventil erfindungsgemäss einen zweiten Dichtungsabschnitt 24, der am Ansatz 9 im Bereich des Auslasses ausgebildet ist.In addition to the sealing section 14 on the closure part 3, the valve according to the invention has a second sealing section 24 which is formed on the extension 9 in the region of the outlet.

Der zweite Dichtungsabschnitt wird durch vier scheibenförmige Abschnitte 25 gebildet. Diese Abschnit­te 25 stehen schräg nach aussen vom Ansatz 9 ab und sind zum Anlass hin gerichtet.The second sealing section is formed by four disk-shaped sections 25. These sections 25 protrude obliquely outwards from the neck 9 and are directed towards the occasion.

Im geschlossenen Zustand, der im rechten Teil­schnitt der Figur dargestellt ist, wird das Ventil im wesentlichen durch den im Behälter (nicht dargestellt) herrschenden Druck geschlossen; lediglich bei entleertem Behälter wird das Ventil durch die Feder 5 aus Gründen der Sicherheit geschlossen. Daraus kann man ableiten, dass die von der Feder 5 durchzuführende Schliessung des Ventils auch von mindestens einem elastischen Abschnitt bewirkt werden kann, der am Ansatz vorgesehen ist.In the closed state, which is shown in the right partial section of the figure, the valve is essentially closed by the pressure prevailing in the container (not shown); only when empty Container, the valve is closed by the spring 5 for safety reasons. From this it can be deduced that the closing of the valve to be carried out by the spring 5 can also be effected by at least one elastic section which is provided on the shoulder.

Durch den Druck wird der Verschlussteil 3 im Ventilkörper 1 zum Auslass hin gedrückt, so dass die scheibenförmigen Abschnitte 16 mit dem Ventilsitz in Dichtungseingriff kommen, wobei jeweils der vordere Ab­schnitt 16 gegen die Sitzfläche 12 gepresst wird, wenn wie beim vorliegenden Ausführungsbeispiel zwei derartige Abschnitte nebeneinanderliegend ausgebildet sind. Die Verformung der scheibenförmigen Abschnitte 16 wird da­durch verursacht, dass der Aussendurchmesser der Ab­schnitte grösser ist als der Innendurchmesser des den erfindungsgemässen Ventilsitz bildenden Abschnittes 11 im Ventilkörper 1.The closing part 3 in the valve body 1 is pressed towards the outlet by the pressure, so that the disk-shaped sections 16 come into sealing engagement with the valve seat, the front section 16 in each case being pressed against the seat surface 12 if, as in the present exemplary embodiment, two such sections lie side by side are trained. The deformation of the disc-shaped sections 16 is caused by the fact that the outside diameter of the sections is larger than the inside diameter of the section 11 forming the valve seat according to the invention in the valve body 1.

Eine weitere Möglichkeit der Ausbildung des erfindungsgemässen Ventilsitzes ergibt sich daraus, dass der an die Sitzfläche 12 angrenzende Abschnitt konisch oder zylinderförmig ausgebildet ist.Another possibility of designing the valve seat according to the invention results from the fact that the section adjoining the seat surface 12 is conical or cylindrical.

Im offenen Zustand, der im linken Teilschnitt der Figur dargestellt ist, wird der Verschlussteil 3 des Ventils durch einen gestrichelt dargestellten Ab­schnitt einer Spritzeinrichtung oder dergleichen gegen den Druck im Behälter verschoben, so dass Material aus dem Behälter ausströmen kann. Dabei wird gleichzeitig der zweite Dichtungsabschnitt 24 mit dem die Oeffnung des Ventils bewirkenden Abschnitt in Dichtungseingriff gebracht, um das Austreten von Fluid aus dem Behälter in den Deckel 2 zu verhindern. Dadurch wird auch eine Verschmutzung durch schwer zu beseitigendes Fluid z.B. Polyurethan-Schaum verhindert.In the open state, which is shown in the left partial section of the figure, the closure part 3 of the valve is displaced by a portion of a spraying device or the like shown in dashed lines against the pressure in the container, so that material can flow out of the container. At the same time, the second sealing section 24 is brought into sealing engagement with the section causing the opening of the valve in order to prevent fluid from escaping from the container into the lid 2. This also causes contamination by fluid that is difficult to remove, e.g. Prevents polyurethane foam.
