Abstract

A valve has a base body fitted in an opening and having a through passage formed at one end with a first valve surface. A valve element in the base body and has axial ends one of which forms second valve surface sealingly fittable with the first valve surface to close the through passage. A stem in the through passage is coupled to the valve element to move it between the closed and open positions. A plurality of abutment arms projecting inward from an inner peripheral wall of the through passage define with a shaft region of the valve element a clearance and define a radial gap between opposite arms which is greater than a radial dimension of the shaft region and smaller than a radial dimension of a shoulder of the valve element.

Description

Die Erfindung betrifft eine Ventilanordnung, bestehend aus einem Basiskörper zur Montage an einer zu verschliessenden Öffnung eines Behälters, Schlauches oder dgl.The invention relates to a valve arrangement, consisting of a base body for mounting on an opening to be closed a container, hose or the like.

Sie betrifft insbesondere eine Ventilanordnung, die das Einführen und/oder die Entnahme eines flüssigen, gasförmigen oder pulvrigen Fluids in bzw. aus einem Behälter oder Beutel mittels eines von aussen betätigbaren Stössels oder einer Nadel ermöglicht, die mit einem Schlauch oder dgl. verbunden sein können, durch den das Fluid zu- bzw. abgeführt werden kann. Diese Vorgänge werden häufig automatisch gesteuert und spielen sich auf engstem Raum ab. Bekannt ist eine gattungsgemässe Ventilanordnung ( WO 98/48203 ) mit einem Ventilelement, das ausserhalb einer Fluiddurchgangspassage der Ventilanordnung vorgesehen ist. Dies erfordert aufwändige bauliche Massnahmen, die die Fertigung und Montage der Ventilanordnung erschweren und kontraproduktiv für eine Minimierung der Abmessungen der Ventilanordnung sind. Bekannt ist es ferner ( WO 95/23972 ), statt separat gefertigter Aufbauteile eine einstückige Anordnung vorzusehen, wobei das Ventilelement weiterhin ausserhalb einer Fluiddurchgangspassage vorgesehen ist. Zwar wird die Fertigung durch die einstückige Bauweise erleichtert, jedoch unterscheidet sich die Ventilanordnung ansonsten nicht von der bekannten vorerwähnten zweiteiligen Anordnung und können darüber hinaus unerwünschte Formungsgrate entstehen, die die Dichtfunktion der Ventilanordnung beeinträchtigen können. Zum Stand der Technik wird ferner verwiesen auf US-A-3 768 501 und 3 871 422 .In particular, it relates to a valve assembly which allows the introduction and / or removal of a liquid, gaseous or powdery fluid into or out of a container or bag by means of an externally actuable plunger or needle which may be connected to a hose or the like through which the fluid can be added or removed. These processes are often controlled automatically and take place in a confined space. A generic valve arrangement is known ( WO 98/48203 ) with a valve element which is provided outside a fluid passage passage of the valve assembly. This requires complex structural measures that complicate the manufacture and assembly of the valve assembly and are counterproductive for minimizing the dimensions of the valve assembly. It is also known ( WO 95/23972 ), Instead of separately manufactured body parts to provide a one-piece arrangement, wherein the valve element is further provided outside a fluid passage passage. Although the production is facilitated by the one-piece design, but the valve assembly is otherwise not different from the known aforementioned two-piece arrangement and can also undesirable Formungsgrate arise that may affect the sealing function of the valve assembly. The prior art is further referred to US-A-3,768,501 and 3,871,422 ,

Durch die Erfindung soll demgegenüber eine Ventilanordnung der eingangs erwähnten Art mit zuverlässiger Dichtfunktion geschaffen werden, die robust ist und sich leicht baulich minimieren lässt. Ferner sollen die Aufbauteile der Ventilanordnung wirtschaftlich durch Spritzgiessen gefertigt und mit wenigen Schritten, vorzugsweise automatisch, zu einer einsatzfertigen Einheit zusammengesetzt werden können.By contrast, a valve arrangement of the type mentioned above with reliable sealing function is to be created by the invention, which is robust and easy structurally minimized. Furthermore, the structural parts of the valve assembly are to be manufactured economically by injection molding and in a few steps, preferably automatically, can be assembled into a ready-to-use unit.

Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Die Erfindung erlaubt die Bereitstellung einer Ventilanordnung, bei der das Ventilelement innerhalb der Umrisslinien des Basiskörpers, z.B. eines Rohrstückes, oder Einschweissteiles angeordnet sein kann und diese Lage weder in der Schliess- noch Freigabeposition zu verlassen braucht. Dies ermöglicht eine bauliche Minimierung der Ventilanordnung unter die Abmessungen der Bohrung oder Öffnung, mit der die Ventilanordnung zusammenwirken soll, so dass sie wie eine gewöhnlicher Stopfen verwendet werden kann. Gleichzeitig ist die Ventilanordnung weniger störanfällig gegenüber äusseren Einflüssen als die eingangs erwähnten bekannten Anordnungen, da keine vorstehenden Teil vorhanden sind, an denen sich beim Entleeren eines Behälters dessen Wandteile anlegen können. Die wesentlichen Aufbauteile der Ventilanordnung, nämlich deren Basiskörper und Ventilelement, stellen wirtschaftlich zu fertigende Kunststoffformteile dar. Deren Montage kann in einem Schritt, vorzugsweise automatisch erfolgen.This object is solved by the features of claim 1. The invention allows the provision of a valve arrangement in which the valve element is located within the contours of the base body, e.g. a pipe section, or weld-in part can be arranged and this position needs to leave neither in the closing nor release position. This allows for structural minimization of the valve assembly below the dimensions of the bore or aperture with which the valve assembly is intended to cooperate so that it can be used as a conventional plug. At the same time, the valve arrangement is less susceptible to interference from external influences than the known arrangements mentioned at the outset, since there are no projecting parts on which the wall parts can be created when a container is emptied. The essential components of the valve assembly, namely the base body and the valve element, are economically produced plastic molded parts. Their assembly can be done automatically in one step, preferably.

Obschon die Erfindung nachfolgend in Verbindung mit der Abdichtung eines Rohres beschrieben wird, in das die Ventilanordnung nach Art eines Stopfens eingesetzt und z.B. durch Presssitz dichtend gehalten sein kann, ist die Erfindung auf diese Anwendung nicht beschränkt. Vielmehr kann die Ventilanordnung auch in anderer Weise, insbesondere als Einschweissteil zum Einsetzen in eine schlitzförmige Öffnung eines Behälters aus folienartigem Material ausgebildet sein, wobei sie mit dem Folienmaterial des Behälters durch Schweissen oder in einer anderen geeigneten Weise dicht verbunden sein kann. Der grundsätzliche Aufbau eines Einschweissteiles ist dem Fachmann bekannt, so dass sich diesbezügliche nähere Erläuterungen erübrigen.Although the invention will hereinafter be described in connection with the sealing of a pipe into which the valve assembly is inserted in the manner of a plug and e.g. can be kept sealed by press fit, the invention is not limited to this application. Rather, the valve assembly can also be formed in another way, in particular as Einschweissteil for insertion into a slot-shaped opening of a container made of film-like material, which may be tightly connected to the film material of the container by welding or in another suitable manner. The basic structure of a weld-in part is known to the person skilled in the art, so that there is no need for further explanation in this regard.

Die Ventilanordnung umfasst, wie dargestellt, einen rohrförmigen Basiskörper 1, der in das Rohr 2 nach Art eines Stopfens eingeführt ist. Der Basiskörper 1 ist von einer Durchgangspassage 3 durchsetzt, die sich von einem axialen Ende des Basiskörpers 1 zu dessen anderen axialen Ende erstreckt. In der Durchgangspassage 3 ist ein Ventilelement 4 angeordnet, das einen zentralen Schaftbereich 5 mit einer verringerten radialen Abmessung D1 umfasst, der sich zwischen endseitigen, in den umfänglichen Abmessungen verdickten Bereichen 6, 7 erstreckt. Der eine verdickte Bereich 6 kann im Querschnitt eine kelch- oder napfförmige Konfiguration haben und weist eine äussere Umfangsfläche 8 auf, die einen ersten Ventilsitz schafft. Eine weitere innere Umfangsfläche 9 ist an einem Mündungs- oder Endbereich 10 des Basiskörpers 1 nahe einem axialen Ende der Durchgangspassage 3 vorgesehen ist und schafft einen zweiten Ventilsitz. Zwischen den Ventilsitzen 8, 9 besteht eine dichtende Beziehung, wenn sich das Ventilelement 4 in seiner in der Zeichnung gezeigten Schliessposition befindet, bei der die Durchgangspassage 3 abgedichtet ist.The valve assembly comprises, as shown, a tubular base body 1 which is inserted into the tube 2 in the manner of a plug. The base body 1 is penetrated by a through-passage 3, which extends from one axial end of the base body 1 to the other axial end. In the through passage 3, a valve element 4 is arranged, which comprises a central shaft portion 5 with a reduced radial dimension D 1 , which extends between end-side, in the circumferential dimensions thickened regions 6, 7. The one thickened region 6 may have a cup or cup-shaped configuration in cross-section and has an outer peripheral surface 8 which provides a first valve seat. Another inner peripheral surface 9 is provided at an orifice portion 10 of the base body 1 near an axial end of the through passage 3, and provides a second valve seat. There is a sealing relationship between the valve seats 8, 9 when the valve member 4 is in its closing position shown in the drawing, in which the through passage 3 is sealed.

Der gegenüberliegende andere verdickte Bereich 7 des Ventilelementes 4 enthält eine sich weg vom Schaftbereich 5 öffnende Profilausnehmung 11, in die ein profilierter Kopfteil 12 eines rohrförmigen Stösselelementes 13 eingreifen kann, um in kuppelnder um eine Füll- oder Absaugeinrichtung für ein Medium handeln. Das Stösselelement 13 kann in die Durchgangspassage 3 seitens deren anderen axialen Endes eingeführt werden und mit einem Rohr oder Schlauch (nicht gezeigt) verbunden sein, über den ein Fluid zugeführt werden kann. Am äusseren Umfang des Stösselelementes 13 kann eine Dichtung 14 in Gestalt z.B. eines O-Ringes angeordnet sein, die mit einem benachbarten Bereich des inneren Umfanges des Basiskörpers 1 in eine dichtende Beziehung treten kann. In der Umfangswand des Stösselelementes 13 nahe dem Kopfstück 12 sind Durchbrechungen 15 vorgesehen, durch die das Fluid aus dem Inneren des Stösselelementes 13 in die Durchgangspassage 3 gelangen kann. Das Stösselelement 13 kann bei Bedarf aus dem kuppelnden Eingriff mit dem Ventilelement 4 herausgebracht werden.The opposite other thickened region 7 of the valve element 4 includes a profile recess 11 which opens away from the shaft region 5 and into which a profiled head part 12 of a tubular plunger element 13 can engage to engage in coupling to act as a filling or suction device for a medium. The plunger member 13 may be inserted into the passageway 3 from the other axial end thereof and connected to a pipe or hose (not shown) through which fluid can be supplied. On the outer circumference of the plunger element 13, a seal 14 may be arranged in the form of, for example, an O-ring, which may enter into a sealing relationship with an adjacent region of the inner circumference of the base body 1. In the peripheral wall of the plunger element 13 near the head piece 12 apertures 15 are provided, through which the fluid can pass from the interior of the plunger element 13 in the passage passage 3. If necessary, the plunger element 13 can be brought out of the coupling engagement with the valve element 4.

Vom inneren Umfang des Basiskörpers 1 nahe dem zweiten Ventilsitz 9 ragt eine Vielzahl (vorliegend vier) in gleichem Umfangsabstand voneinander angeordnete Anschlagarme 16 schräg nach innen und in Richtung auf den verdickten Bereich 7 des Ventilelementes 4. Die Anschlagarme 16 haben axiale Anschlagflächen 17, mit denen eine ringförmige Schulterfläche 18 am verdickten Bereich 7 des Ventilelementes 4 in Anlage kommen kann, um eine axiale Bewegung des Ventilelementes 4 in Richtung auf dessen Freigabeposition zu begrenzen, bei der der erste Ventilsitz 8 ausser der dichtenden Beziehung mit dem zweiten Ventilsitz 9 steht. Die axiale Verschiebung des Ventilelementes 4 kann dadurch erfolgen, dass das mit dem Ventilelement 4 in kuppelnder Beziehung stehende Stösselelement 13 in der Durchgangspassage 3 vorgeschoben wird.From the inner circumference of the base body 1 near the second valve seat 9 projects a plurality (four in the present case) at the same circumferential distance from each other arranged stop arms 16 obliquely inward and toward the thickened portion 7 of the valve element 4. The stop arms 16 have axial stop surfaces 17, with which an annular shoulder surface 18 may abut the thickened portion 7 of the valve element 4 to limit axial movement of the valve element 4 towards its release position, wherein the first valve seat 8 is out of sealing relationship with the second valve seat 9. The axial displacement of the valve element 4 can take place in that the plunger element 13, which is in coupling relationship with the valve element 4, is advanced in the through passage 3.

In der gezeigten Ruhe- oder Betriebsstellung enden die Anschlagarme 16 in einem nahen Abstand vom äusseren Umfang 20 des Schaftbereiches 5 des Ventilelementes 4, wie dies bei 19 angedeutet ist, so dass zwischen den Armen 16 und dem Ventilelement 4 keine berührende Eingriffnahme zustande kommt. Die Arme 16 sind so dimensioniert, dass sie unter einer darauf wirkenden axialen Kraft aus der Ruhe- oder aussen abgebogen werden können bzw. nachgeben können. In der Ruhe- oder Betriebsstellung definieren die Anschlagarme 16 einen freien inneren Durchlass 24 mit einer Durchlassweite d, vgl. Fig. 3,In the rest or operating position shown, the stop arms 16 terminate at a close distance from the outer circumference 20 of the shaft portion 5 of the valve element 4, as indicated at 19, so that between the arms 16 and the valve element 4 no touching intervention comes about. The arms 16 are dimensioned so that they under a force acting thereon from the rest or can be bent outside or yield. In the rest or operating position, the stop arms 16 define a free inner passage 24 with a passage width d, cf. 3,

Wie weiter Fig. 2 zeigt, können an dem inneren Umfang des Basiskörpers 1 eine Vielzahl von Führungsleisten 21 (vorliegend vier Leisten) in gleichem Umfangsabstand voneinander angeformt sein, die sich in axialer Richtung erstrecken und innere Führungsflächen 22 aufweisen, längs denen der verdickte Bereich 7 des Ventilelementes 4 bewegt werden kann. Die radiale Abmessung D2 des äusseren Umfangs 23 des verdickten Bereiches 7 ist so, dass ein minimaler freier Spalt zu den Führungsflächen 22 der Führungsleisten 21 eingehalten wird und der verdickte Bereich 7 nur dann eine Stütze an den Führungsflächen 22 erfährt, wenn das Ventilelement 4 aus seiner vorgegebenen axialen und radialen Ausrichtung durch äussere Störkräfte herausgebracht wird.As further shown in FIG. 2, at the inner circumference of the base body 1, a plurality of guide rails 21 (in the present case four strips) may be integrally formed at the same circumferential distance, which extend in the axial direction and have inner guide surfaces 22, along which the thickened region 7 of the valve element 4 can be moved. The radial dimension D 2 of the outer periphery 23 of the thickened region 7 is such that a minimum free gap is maintained to the guide surfaces 22 of the guide rails 21 and the thickened region 7 only receives a support on the guide surfaces 22, when the valve element 4 from its predetermined axial and radial alignment is brought out by external disturbing forces.

Wie in der Zeichnung dargestellt ist, ist das Ventilelement 4 in seiner Freigabe- als auch Schliessposition innerhalb der umfänglichen und axialen Begrenzungen der Durchgangspassage 3 bzw. des Basiskörpers 1 aufgenommen. Dies wird durch die nachgiebigen Anschlagarme 16 ermöglicht, indem diese bei Einsetzen des Ventilelementes 4 in die Durchgangspassage 3 seitens deren Mündungsbereiches 10 weggebogen werden können, so dass die Durchlassweite d des Durchlasses 24 vorübergehend so vergrössert wird, dass der verdickte Bereich 7 des Ventilelementes 4 die Anschlagarme 16 passieren kann. Danach federn die Anschlagarme 16 in ihre gezeigten Ausgangspositionen zurück, um als Anschläge zu dienen, die die Bewegung des Ventilelementes 4 in die Freigabeposition begrenzen und gleichzeitig das Ventilelement an einem Herausfallen aus der Durchgangspassage hindern.As shown in the drawing, the valve element 4 is received in its release as well as closing position within the circumferential and axial boundaries of the through passage 3 and the base body 1, respectively. This is made possible by the resilient abutment arms 16, in that they can be bent away when the valve element 4 is inserted into the through-passage 3 on the part of its mouth region 10, so that the passage width d of the passage 24 is temporarily enlarged so that the thickened region 7 of the valve element 4 Stop arms 16 can happen. Thereafter, the stop arms 16 spring back to their initial positions shown to serve as stops which limit the movement of the valve element 4 to the release position and at the same time prevent the valve element from falling out of the passageway.

Die Schliessposition, die durch die Eingriffnahme zwischen den ersten und zweiten Ventilsitzen 8, 9 definiert ist, kann in anderer geeigneter Weise anschlagbegrenzt Ventilelementes 4 in Anlage mit einer Schulter 26 am Basiskörper 1 treten, die nahe dem zweiten Ventilsitz 9 vorgesehen ist.The closing position, which is defined by the engagement between the first and second valve seats 8, 9, may stop limit in some other suitable manner Valve element 4 come into contact with a shoulder 26 on the base body 1, which is provided near the second valve seat 9.

Obschon die Erfindung die vollständige Integration des Ventilelementes innerhalb der Durchgangspassage des Basiskörpers ermöglicht, ist sie hierauf nicht beschränkt. Die ersten und zweiten Ventilsitze könnten auch ausserhalb der axialen Enden der Durchgangspassage vorgesehen sein, indem am Ventilelement ein Anschlagflansch mit einer Dichtfläche angeformt sein kann, die mit einer stirnseitigen Dichtfläche des Basiskörpers in dichtende Beziehung treten kann. Die dichtende Beziehung könnte alleine durch die Wirkung eines Überdrucks im Behälter aufrechterhalten werden. Anstelle von vier oder mehr Anschlagarmen und Führungsleisten kann auch nur ein Paar diametral gegenüberliegende derartige Anschlagarme und Führungsleisten vorgesehen sein. Der Basiskörper und das Ventilelement sind, vorzugsweise nach dem Spritzgiessverfahren gefertigte, separate Kunststoffformteile aus gleichen oder unterschiedlichen Kunststoffmaterialien.Although the invention enables complete integration of the valve element within the passageway of the base body, it is not limited thereto. The first and second valve seats could also be provided outside the axial ends of the passage passage by the valve element, a stop flange may be integrally formed with a sealing surface which can be in sealing relationship with a front-side sealing surface of the base body. The sealing relationship could be maintained solely by the effect of positive pressure in the container. Instead of four or more stop arms and guide rails and only a pair of diametrically opposed such stop arms and guide rails can be provided. The base body and the valve element are, preferably manufactured by the injection molding, separate plastic moldings of the same or different plastic materials.
