Definitions
- the present invention relates to a valve according to the preamble of claim 1.
- 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.
- 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.
- 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.
- a valve which consists of two parts, namely a tubular valve body with a valve seat and a closure part with a sealing section.
- the valve body has an elastic section and at the same time forms an actuating member.
- the closure part is held in the valve body above the elastic section, so that when the valve body is pressed in the axial direction, the closure part is advanced with respect to the valve body and the sealing section is lifted off the valve seat. If the valve body is released, it is pushed back through the elastic section and the sealing section is pulled to the valve seat.
- the valve body is firmly mounted in a groove which is formed on the neck of the container lid.
- valve body seals the container lid only to a limited extent, so that the storage of the containers is limited in time, that the restoring means for the closure part is arranged downstream of the valve seat in the flow direction, thereby causing the discharge of fluid, in particular polyurethane foam , can be hindered by solidified material in the valve housing, and that the valve can be opened by eccentric pressure, which requires special measures in the storage of the containers.
- the object on which the invention is based is to create a valve which manages without separate sealing members, seals the container in a gas-tight manner and is opened in a targeted manner when it is inserted into a spraying device.
- the closure part is essentially cylindrical and if the sealing section has at least one elastically deformable, disk-shaped section which projects essentially radially from the closure part and rests against the valve seat under deformation. Due to the deformation of the disk-shaped sealing sections that occurs when the valve is closed, a secure tightness can be ensured.
- the tightness can be further improved by using two sealing sections.
- the extension is essentially cylindrical and has at least one elastically deformable, disc-shaped section which projects essentially radially from the extension in order to seal the valve when it is inserted.
- 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 extends essentially parallel to the base of the section and inwards extends, this edge section being enclosed by the plastic part in order to seal the valve in a gas-tight manner.
- 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 arranged between the closing part and the holding part is used.
- 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.
- the valve body 1 also has a through hole 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 hole.
- the closure member 3 has a cylindrical body with a flange 13 at one end, a sealing section 14 formed adjacent to the flange 13, and four grooves 15 extending from the sealing section 14 to the other end of the body.
- the grooves 15 are semicircular.
- the sealing section 14 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.
- the holding part 4 is designed as a cap which can be placed on the extension 8.
- 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.
- a recess 21 is provided on the inside of the cap, in which the spring 5 is centered.
- the spring 5 is held on a shoulder 22 of the closure part 3.
- valve according to the invention has a second sealing section 24 which is formed on the extension 9 in the region of the outlet.
- 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.
- the valve 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.
- the closure part 3 in the valve body 1 is pressed toward 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.
- valve seat 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.
- the closure part 3 of the valve is displaced by a section 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.
- 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.

Abstract
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
Derartige Ventile sind bekannt und werden von dem Behälter getragen. Der Behälter besitzt einen Deckel. 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 Dichtungorgan drückt. 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 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. 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.
Aus der US-A-4 522 318 ist ein Ventil bekannt, das aus zwei Teilen besteht und zwar einem rohrförmigen Ventilkörper mit einem Ventilsitz und einem Verschlussteil mit Dichtungsabschnitt. Der Ventilkörper weist einen elastischen Abschnitt auf und bildet gleichzeitig ein Betätigungsorgan. Der Verschlussteil ist im Ventilkörper oberhalb des elastischen Abschnittes gehalten, so dass beim Drücken des Ventilkörpers in axialer Richtung der Verschlussteil bezüglich dem Ventilkörper vorgeschoben und der Dichtungsabschnitt vom Ventilsitz abgehoben wird. Wird der Ventilkörper freigegeben, so wird durch den elastischen Abschnitt zurückgeschoben und der Dichtungsabschnitt an den Ventilsitz gezogen. Der Ventilkörper ist in einer Rille fest montiert, die am Hals des Behälterdeckels ausgebildet ist.From US-A-4 522 318 a valve is known which consists of two parts, namely a tubular valve body with a valve seat and a closure part with a sealing section. The valve body has an elastic section and at the same time forms an actuating member. The closure part is held in the valve body above the elastic section, so that when the valve body is pressed in the axial direction, the closure part is advanced with respect to the valve body and the sealing section is lifted off the valve seat. If the valve body is released, it is pushed back through the elastic section and the sealing section is pulled to the valve seat. The The valve body is firmly mounted in a groove which is formed on the neck of the container lid.
Dieses Ventil hat den Nachteil, dass der Ventilkörper den Behälterdeckel nur beschränkt gasdicht abschliesst, so dass die Lagerhaltung der Behälter zeitlich beschränkt ist, dass das Rückstellmittel für den Verschlussteil in Strömungsrichtung nach dem Ventilsitz angeordnet ist, wodurch das Ausbringen von Fluid, insbesondere Polyurethan-Schaum, durch verfestigtes Material im Ventilgehäuse behindert werden kann, und dass das Ventil durch exzentrischen Druck geöffnet werden kann, wodurch besondere Massnahmen bei der Lagerhaltung der Behälter erforderlich sind.This valve has the disadvantage that the valve body seals the container lid only to a limited extent, so that the storage of the containers is limited in time, that the restoring means for the closure part is arranged downstream of the valve seat in the flow direction, thereby causing the discharge of fluid, in particular polyurethane foam , can be hindered by solidified material in the valve housing, and that the valve can be opened by eccentric pressure, which requires special measures in the storage of the containers.
Die der Erfindung zugrunde liegende Aufgabe besteht darin, ein Ventil zu schaffen, das ohne separate Dichtungsorgane auskommt, den Behälter gasdicht abschliesst und beim Einsetzen in eine Spritzeinrichtung gezielt geöffnet wird.The object on which the invention is based is to create a valve which manages without separate sealing members, seals the container in a gas-tight manner and is opened in a targeted manner when it is inserted into a spraying device.
Diese Aufgabe wird erfindungsgemäss mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.According to the invention, this object is achieved with the characterizing features of
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 und billig herstellbar ist.The advantages that can be achieved with the invention are essentially that containers with different fluids e.g. Propellant gas and polyurethane can be stored in any position without reducing the tightness, and that the valve has a minimum of individual parts and is inexpensive to manufacture.
Es ist insbesondere von Vorteil, wenn der Verschlussteil im wesentlichen zylinderförmig ausgebildet ist, und wenn der Dichtungsabschnitt mindestens einen elastisch verformbaren, scheibenförmigen Abschnitt aufweist, der im wesentlichen radial vom Verschlussteil absteht und unter Verformung an den Ventilsitz anliegt. 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 elastically deformable, disk-shaped section which projects essentially radially from the closure part and rests against the valve seat under deformation. 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 mindestens einen elastisch verformbaren, scheibenförmigen Abschnitt aufweist, der 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 has at least one elastically deformable, disc-shaped section which projects essentially radially from the extension in order to seal the valve when it is inserted.
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 extends essentially parallel to the base of the section and 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
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
Der Ventilkörper 1 hat ferner eine Durchgangsbohrung 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
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 14 bis zum anderen Ende des Körpers erstrecken. Die Rillen 15 sind halbrund.The
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-
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
Andererseits wird die Feder 5 an einem Ansatz 22 des Verschlussteiles 3 gehalten.On the other hand, the
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
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-
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
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
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
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-hand partial section of the figure, the
