Definitions
- the present invention relates to an arrangement for the pluggable flange-mounting of a bottle-shaped, pressurized, gas-containing pressure vessel, with a controllable valve device to a gas extraction device with a control device for regulating the pressure of the extracted gas, the control device of the gas extraction device with the valve device Pressure vessel cooperates.
- Such arrangements can be used, for example, in vending machines, by means of which beverage concentrates are mixed with soda water to form a soft drink.
- the soda water is brought about by enriching fresh water with CO z gas in a preferably cooled storage vessel.
- CO storage containers
- the CO 2 storage containers are usually screwed to the gas extraction device.
- the present invention is based on the object of providing an arrangement for the pluggable flange-mounting of a bottle-shaped pressure vessel with a gas extraction device, in which simple operability and a functionally reliable connection is ensured despite the simple construction.
- An arrangement which particularly fulfills these tasks is characterized in that a manually operable pivoting lever is mounted on the gas extraction device, via which the valve device of the pressure container can be gripped on actuating flanges and pressed against the connection opening of the extraction device.
- valve device can be grasped via the actuating flanges and pressed against the connection opening of the removal device by means of the manually operated pivoting lever articulated on the gas removal device.
- the force curve to achieve the contact pressure therefore only takes place in the immediate vicinity of the flange parts to be joined. This largely prevents damage to the flange parts.
- elastic contact means for * tolerance compensation can largely be dispensed with, so that damage in the flange area has a high probability that this will be recognizable during the flanging process by difficult or not feasible operating conditions. This draws the operator's attention to faulty conditions in the flange areas, which can also present themselves as dirt.
- the flange area between the removal device and the valve device is arranged between the bearing point of the pivot lever on the removal device and the actuating surfaces of the valve arrangement for the pivot lever.
- this arrangement according to the invention is characterized in that actuating lugs for the pivoting lever of the removal device are arranged laterally opposite one another on the valve device. In this way, points of attack are created in a simple manner for the pressing mechanism implemented by the manually actuable pivoting lever.
- a further improvement in the functionality of the arrangement according to the invention can be achieved in that two engagement areas are arranged between the valve device and the pivoting lever. In a first swivel phase of the swivel lever, the valve seats are moved against each other into the working position over the one attack area over which a longer stroke approach between the valve device and the removal device can be achieved, while the working position with the required contact pressure can be finally and reliably achieved in a short stroke over the second attack area.
- An additional improvement of the arrangement according to the invention is given if a short-stroke resilient intermediate member is arranged between the valve device and the removal device. This resilient intermediate member can preferably be arranged directly in the swivel lever.
- An arrangement also meets the requirements placed on it to a particular extent in that a centering device for the valve device of the pressure vessel, which is open at the front perpendicular to the receiving direction, is arranged in the vicinity of the connection opening of the removal device, and in that the valve device is essentially perpendicular to the centering movement via a pressing mechanism can be pressed against the connection opening of the removal device.
- a configured in accordance with these inventive features arrangement Complies the requirements imposed on them particularly true in so far that the opened centralizer end face perpendicular g to Anflanschrichtun causes a convenient and easy to perform pre-centering of the two flange parts for the valve device to each other and that from this position via the pressing mechanism Valve device in the gas-tight system against the connection opening of the Removal device is movable and can be pressed against it. This largely prevents damage to the flange parts.
- a further improvement in operating convenience can be achieved in that stationary guide links for the pressure vessel are arranged in the device housing, via which the valve assembly is guided into the area of the centering device when the pressure vessel is inserted. With these measures, a centering funnel is practically implemented.
- an arrangement serves the requirements imposed on it in accordance with the present task by measures which are characterized in that the valve device is cranked so that its connection opening is oriented at an angle to the axis of the pressure vessel.
- the valve arrangement is preferably bent essentially at right angles.
- the right-angled bend of the valve device with respect to the axis of the pressure vessel offers particularly favorable preconditions for handling the pressure vessel, in particular because the valve arrangement can be flanged onto the removal device perpendicular to the axis of the pressure vessel.
- the Voraussetzug is created that the Anflanschamba extends from the center of gravity of the pressure vessel, so that its mass is only slightly g on the HS Anflanschvor effect.
- the angled design of the valve device can preferably also be used in such a way that the valve section opposite the connection opening forms an engagement surface for a swivel lever arranged on the removal device.
- an arrangement of the invention fulfills in accordance the requirements according to the object to it 'provided by the fact that the pressure vessel is arranged aligned in its installed position in the device housing substantially vertically and in its upper portion has an angled valve means with laterally oriented flange opening, that in the vicinity of the counter Valve flange directed connection opening of the gas sampling device a (upward open) pre-centering device for the valve flange is arranged and that a pivoting lever locking mechanism mounted pivotably on the gas sampling device makes the valve device gas-tight across the connection opening of the gas sampling device.
- An arrangement designed according to these features according to the invention corresponds to the tasks placed on it in many respects.
- To install the pressure vessel in the device it is only necessary in a first operating step to grasp the pressure vessel in the region of the cranked valve device and to insert it with the bottom first into a receiving chamber of the device. Due to the preferably arranged guide links, the gas pressure container is brought into the area of its final working position and is detected in the area of the angled valve device by the pre-centering device arranged in front of the gas sampling device. Now it is only necessary to move the valve device completely towards the gas sampling device by actuating the swivel lever locking mechanism and to connect the two functional parts to one another in a gas-tight manner.
- the gas extraction device should preferably be designed in such a way that the center of gravity of the pressure container lies below the centering device for the angled part of the valve device.
- the weight of the gas pressure vessel does not have a canting effect on the flange connection.
- the arrangement according to the invention is preferably characterized in that a further centering pipe socket of the valve device for connection to the removal device is arranged within an outer pipe socket in the area of the connection opening of the valve device.
- the arrangement shown serves for the removal of CO 2 gas from a pressure vessel 1 via a gas extraction device 2 for a carbonator of a vending machine. Fresh water is enriched in this carbonizer with the CO z gas.
- the gas extraction device 2 contains control elements which, in conjunction with a valve tappet of a valve device 3 arranged on the gas pressure container 1, regulately reduce the gas pressure prevailing within the gas pressure container 1 to the operating pressure required in the carbonator.
- the gas sampling device 2 is fastened in the device housing 4 and is therefore part of the device.
- the gas pressure vessel 1 and the valve device 3 form a functional unit which is to be flanged to the gas extraction device 2 for supplying the carbonizer with CO Z gas.
- valve device 3 is cranked for this purpose, ie its connecting flange for the gas extraction device 2 is angled at right angles to the axis of the gas pressure container 1. This results in a connection movement sequence in two stages for the connection of the gas pressure container 1 via the valve arrangement 3 to the gas extraction device 2.
- a gas pressure container 1 which is to be introduced and connected to the device is inserted through the housing opening 5 with its lower end 6 in the front Receiving chamber 7 for the pressure vessel 1 is introduced essentially in the axial direction of the gas pressure vessel 1. Passed through the wall sections 8, 9, the gas pressure vessel 1 is inevitably pivoted and brought about the round edge 10 within the device housing 4 into a position in which the valve arrangement 3 reaches the area of the gas extraction device 2.
- this gas sampling device 2 Upstream of this gas sampling device 2 is a centering device 11, via which the angled section of the valve device 3 is detected, so that the connecting flange of the valve device 3 is centered with the complementary connecting flange of the gas sampling device 2.
- the upstream of the gas sampling device 2 centering device 11 - as shown in Fig. 3 - is open at the top U-shaped, so that when the gas pressure container 1 is inserted, the cranked wedge, indicated by dash-dotted lines in Fig. 3 12 of the valve device until it comes to rest on the bottom of this centering device 11.
- the installation position of the gas pressure vessel 1 is selected so that its center of gravity is essentially below this support point between the centering device 11 and the bent part 12 de valve device. This pre-centered work situation is essentially stable.
- a manually operable pivot lever 13 is used, which is pivotably mounted on axle attachments 14 of the gas sampling device 2.
- the working position of the pivot lever 13 is shown. The latter engages actuating lugs 16 of the valve device 3 via beveled actuating surfaces 15.
- the corresponding flange parts of the valve device 3 and the gas sampling device 2 are axially joined by the pivoting movement of the manually operated pivot lever 13 carried out from above.
Abstract
Description
Die vorliegende Erfindung bezieht sich auf eine Anordnung zum steckbaren Anflanschen eines flaschenartig ausgebildeten, unter Druck stehendes, Gas enthaltenden Druckbehälters, mit einer steuerbaren Ventileinrichtung an eine Gasentnameeinrichtung mit einer Steuereinrichtung zum Regeln des Druckes des entnommenen Gases, wobei die Steuereinrichtung der Gasentnahmeeinrichtung mit der Ventileinrichtung des Druckbehälters zusammenwirkt.The present invention relates to an arrangement for the pluggable flange-mounting of a bottle-shaped, pressurized, gas-containing pressure vessel, with a controllable valve device to a gas extraction device with a control device for regulating the pressure of the extracted gas, the control device of the gas extraction device with the valve device Pressure vessel cooperates.
Derartige Anordnungen können beispielsweise Anwendung finden in Getränkeautomaten, durch welche Getränkekonzentrate mit Sodawasser zu einem Erfrischungsgetränk gemischt werden. Bei derartigen Geräten wird das Sodawasser durch Anreichern von Frischwasser mit COz -Gas in einem bevorzugterweise gekühlten Vorratsgefäß bewirkt. Für den individuellen Einsatz derartiger Geräte ist es zweckmäßig und wünschenswert, die Auswechselbarkeit auch der CO=-Vorratsbehälter möglichst einfach und damit für jedermann durchführbar zu ermöglichen. Üblicherweise werden die CO2 -Vorratsbehälter mit der Gasentnahme-Einrichtung verschraubt. Es ist aber auch bekannt, den CO,-Druckbehälter durch eine Steckverbindung mit der Gasentnahme- Einrichtung zu verbinden und diese Verbindung dadurch aufrecht zu erhalten, daß über diesen Vorratsbehälter ein entsprechender Anpreßdruck geleitet wird.Such arrangements can be used, for example, in vending machines, by means of which beverage concentrates are mixed with soda water to form a soft drink. In such devices, the soda water is brought about by enriching fresh water with CO z gas in a preferably cooled storage vessel. For the individual use of such devices, it is expedient and desirable to make the interchangeability of the CO = storage containers as simple as possible and thus feasible for everyone. The CO 2 storage containers are usually screwed to the gas extraction device. However, it is also known to connect the CO, pressure vessel to the gas extraction device by means of a plug-in connection and to maintain this connection in that a corresponding contact pressure is passed through this reservoir.
Bei den bekannten Anordnungen treten zwei Hauptprobleme auf. Das eine Problem besteht darin, daß das Zusammenführen der Flansche einerseits des Vorratsbehälters und andererseits der Gasentnahmeeinrichtung hohe Sorgfalt geübt werden muß, da dabei leicht in diesem Bereich Beschädigungen auftreten können. Solche Beschädigungen führen aber dann meist zu Gasundichtigkeiten. Das zweite Problem ist darin zu sehen, daß bei den bekannten Steckverbindungen der Anpreßdruck über die gesamte Gasflasche geleitet wird, was ein entsprechend stabiles Gehäuse voraussetzt, welches diese Kräfte aufnehmen kann und zum anderen hohe Ansprüche an die Fertigungsgenauigkeit stellt. Dieses Problem ist über elastische Andruckmittel, beispielsweise über Federdruck, nur bedingt lösbar, da bei zu großzügieer Anwendung dieser Maßnahmen nicht eine ausreichende Sicherheit für eine zuverlässige Verbindung zwischen den beiden Flanschteilen gegeben ist.There are two main problems with the known arrangements. One problem is that great care must be taken to bring the flanges together on the one hand of the storage container and on the other hand of the gas sampling device, since damage can easily occur in this area. Such damage usually leads to gas leaks. The second problem is in it to see that the contact pressure is passed over the entire gas bottle in the known plug connections, which requires a correspondingly stable housing which can absorb these forces and, on the other hand, places high demands on the manufacturing accuracy. This problem can only be solved to a limited extent by means of elastic pressure means, for example by spring pressure, since if these measures are used too generously, there is insufficient security for a reliable connection between the two flange parts.
Der vorliegenden Erfindung liegt nunmehr die Aufgabe zugrunde, eine Anordnung zum steckbaren Anflanschen eines flaschenartig ausgebildeten Druckbehälters mit einer Gasentnahme-Einrichtung bereitzustellen, bei welcher trotz einfachen Aufbaus eine einfache Bedienbarkeit und eine funktionssichere Verbindung gewährleistet ist.The present invention is based on the object of providing an arrangement for the pluggable flange-mounting of a bottle-shaped pressure vessel with a gas extraction device, in which simple operability and a functionally reliable connection is ensured despite the simple construction.
Eine Anordnung, welche diesen gestellten Aufgaben im besonderen Maße gerecht wird, ist erfindungsgemäß dadurch gekennzeichnet, daß an der Gasentnahmeeinrichtung ein handbetätigbarer Schwenkhebel gelagert ist, über welchen die Ventileinrichtung des Druckbehälters an Betätigungsflanschen erfaßbar und gegen die Anschlußöffnung der Entnahmeeinrichtung anpreßbar ist.An arrangement which particularly fulfills these tasks is characterized in that a manually operable pivoting lever is mounted on the gas extraction device, via which the valve device of the pressure container can be gripped on actuating flanges and pressed against the connection opening of the extraction device.
Eine nach diesen erfindungsgemäßen Merkmalen ausgestaltete Anordnung entspricht den an sie gestellten Anforderungen insoweit, daß über den handbetätigbaren, an der Gasentnahmeeinrichtung angelenkten Schwenkhebel die Ventileinrichtung über die Betätigungsflansche erfaßbar und gegen die Anschlußöffnung der Entnahmeeinrichtung anpreßbar ist. Damit findet der Kraftverlauf zur Erzielung des Anpreßdruckes lediglich im unmittelbaren Nahbereich der zusammenzufügenden Flanschteile statt. Beschädigungen der Flanschteile werden dadurch weitestgehend vermieden. Infolge der raltiv kurzen, zu überbrückenden Abstände kann auf elastische Anpreßmittel zum * Toleranzausgleich weitestgehend verzichtet werden, so daß Beschädigungen im Flanschbereich sich mit großer Wahrscheinlichkeit dahin auswirken, daß dies beim Anflanschvorgang durch erschwerte, bzw. nicht durchführbare BetätigunLsbedingungen erkennbar ist. Damit wird die Bedienungsperson auf fehlerhafte Bedingungen in den Flanschbereichen, welche sich auch als Verschmutzungen darstellen können, aufmerksam gemacht.An arrangement designed according to these features according to the invention meets the requirements placed on them to the extent that the valve device can be grasped via the actuating flanges and pressed against the connection opening of the removal device by means of the manually operated pivoting lever articulated on the gas removal device. The force curve to achieve the contact pressure therefore only takes place in the immediate vicinity of the flange parts to be joined. This largely prevents damage to the flange parts. As a result of the relatively short distances to be bridged, elastic contact means for * tolerance compensation can largely be dispensed with, so that damage in the flange area has a high probability that this will be recognizable during the flanging process by difficult or not feasible operating conditions. This draws the operator's attention to faulty conditions in the flange areas, which can also present themselves as dirt.
Aus kraftübertragungs-technischen Gründen ist es zweckmäßig, daß der Anflanschbereich zwischen der Entnahmeeinrichtung und der Ventileinrichtung zwischen der Lagerstelle des Schwenkhebels an der Entnahmeeinrichtung und der Betätigungsflächen der Ventilanordnung für den Schwenkhebel angeordnet ist.For reasons of power transmission, it is expedient that the flange area between the removal device and the valve device is arranged between the bearing point of the pivot lever on the removal device and the actuating surfaces of the valve arrangement for the pivot lever.
Nach einer bevorzugten Ausgestaltung ist diese erfindungsgemäße Anordnung dadurch gekennzeichnet, daß seitlich gegenüberliegend an der Ventileinrichtung Betätigungsansätze für den Schwenkhebel der Entnahmeeinrichtung angeordnet sind. Hiermit sind in einfacher Weise Angriffspunkte für den durch den handbetätigbaren Schwenkhebel realisierten Anpreßmechanismus geschaffen. Eine weitere Verbesserung der Funktionstüchtigkeit der erfindungsgemäßen Anordnung ist dadurch erzielbar, daß zwischen der Ventileinrichtung und dem Schwenkhebel zwei Angriffsbereiche angeordnet sind. Über den einen Angriffsbereich, über welchen eine längerhubiee Annäherung zwischen Ventileinrichtung und Entnahmeeinrichtung erzielbar ist, werden die Ventilsitze in einer ersten Schwenkphase des Schwenkhebels gegeneinander in die Arbeitslage bewegt, während über den zweiten Angriffsbereich endgültig und zuverlässig kurzhubie die Arbeitslage mit dem erforderlichen Anpreßdruck erzielbar ist. Eine zusätzliche Verbesserung der erfindungsgemäßen Anordnung ist dann gegeben, wenn zwischen Ventileinrichtung und Entnahmeeinrichtung ein kurzhubig wirkendes federndes Zwischenglied angeordnet ist. Dieses ferdernde Zwischenglied läßt sich unmittelbar im Schwenkhebel bevorzugterweise anordnen.According to a preferred embodiment, this arrangement according to the invention is characterized in that actuating lugs for the pivoting lever of the removal device are arranged laterally opposite one another on the valve device. In this way, points of attack are created in a simple manner for the pressing mechanism implemented by the manually actuable pivoting lever. A further improvement in the functionality of the arrangement according to the invention can be achieved in that two engagement areas are arranged between the valve device and the pivoting lever. In a first swivel phase of the swivel lever, the valve seats are moved against each other into the working position over the one attack area over which a longer stroke approach between the valve device and the removal device can be achieved, while the working position with the required contact pressure can be finally and reliably achieved in a short stroke over the second attack area. An additional improvement of the arrangement according to the invention is given if a short-stroke resilient intermediate member is arranged between the valve device and the removal device. This resilient intermediate member can preferably be arranged directly in the swivel lever.
Ebenfalls wird eine Anordnung den an sie aufgabengemäß gestellten Anforderungen im besonderen Maße dadurch gerecht, daß im Nahbereich der Anschlußöffnung der Entnahmeeinrichtung eine stirnseitig senkrecht zur Aufnahmerichtung geöffnete Zentriervorrichtung für die Ventileinrichtung des Druckbehälters angeordnet ist, und daß die Ventileinrichtung über einen Anpreßmechanismus im wesentlichen senkrecht zur Zentrierbewegung gegen die Anschlußöffnung der Entnahmeeinrichtung anpreßbar ist. Eine nach diesen erfindungsgemäßen Merkmalen ausgestaltete Anordnung entpricht den an sie gestellten Anforderungen in besonderem Maße insoweit, daß die stirnseitig senkrecht zur Anflanschrichtung geöffnete Zentriervorrichtung für die Ventileinrichtung eine zweckmäßige und leicht durchführbare Vorzentrierung der beiden Flanschteile zueinander bewirkt und daß aus dieser Lage über den Anpreßmechanismus die Ventileinrichtung in die gasdichte Anlage gegen die Anschlußöffnung der Entnahmeeinrichtung bewegbar und an dieser anpreßbar ist. Beschädigungen der Flanschteile werden dadurch weitestgehend vermieden. Eine weitere Verbesserung für den Bedienungskomfort ist dadurch erzielbar, daß ortsfeste Führungskulissen für den Druckbehälter im Gerätegehäuse angeordnet sind, über die beim Einsetzen des Druckbehälters dessen Ventilanordnung in den Bereich der Zentriervorrichtung geleitet wird. Mit diesen Maßnahmen ist praktisch ein Zentrierungstrichter realisiert.An arrangement also meets the requirements placed on it to a particular extent in that a centering device for the valve device of the pressure vessel, which is open at the front perpendicular to the receiving direction, is arranged in the vicinity of the connection opening of the removal device, and in that the valve device is essentially perpendicular to the centering movement via a pressing mechanism can be pressed against the connection opening of the removal device. A configured in accordance with these inventive features arrangement Complies the requirements imposed on them particularly true in so far that the opened centralizer end face perpendicular g to Anflanschrichtun causes a convenient and easy to perform pre-centering of the two flange parts for the valve device to each other and that from this position via the pressing mechanism Valve device in the gas-tight system against the connection opening of the Removal device is movable and can be pressed against it. This largely prevents damage to the flange parts. A further improvement in operating convenience can be achieved in that stationary guide links for the pressure vessel are arranged in the device housing, via which the valve assembly is guided into the area of the centering device when the pressure vessel is inserted. With these measures, a centering funnel is practically implemented.
Weiterhin dient eine Anordnung den an sie gemäß vorliegender Aufgabe gestellten Anforderungen durch Maßnahmen, die dadurch gekennzeichnet sind, daß die Ventileinrichtung gekröpft ausgebildet ist, so daß ihre Anschlußöffnung gegen die Achse des Druckbehälters abgewinkelt ausgerichtet ist. Bevorzugterweise ist die Ventilanordnung im wesentlichen rechtwinklig abgekröpft.Furthermore, an arrangement serves the requirements imposed on it in accordance with the present task by measures which are characterized in that the valve device is cranked so that its connection opening is oriented at an angle to the axis of the pressure vessel. The valve arrangement is preferably bent essentially at right angles.
Die rechtwinklige Abkröpfung der Ventileinrichtung gegenüber der Achse des Druckbehälters bietet besonders günstige Vorbedingungen bei der Handhabung des Druckbehälters, und zwar insbesondere deshalb, da somit die Anflanschung der Ventilanordnung an die Entnahmeeinrichtung senkrecht zur Achse des Druckbehälters erfolgen kann. Damit ist die Voraussetzug geschaffen, daß die Anflanschbewegung entfernt vom Schwerpunkt des Druckbehälters verläuft, so daß dessen Masse sich nur noch geringfügig auf den Anflanschvorgang auswirkt.The right-angled bend of the valve device with respect to the axis of the pressure vessel offers particularly favorable preconditions for handling the pressure vessel, in particular because the valve arrangement can be flanged onto the removal device perpendicular to the axis of the pressure vessel. Thus, the Voraussetzug is created that the Anflanschbewegung extends from the center of gravity of the pressure vessel, so that its mass is only slightly g on the HS Anflanschvor effect.
Die abgewinkelte Ausbildung der Ventileinrichtung läßt sich bevorzugt auch dahingehend nutzen, daß die der Anschlußöffnung gegenüberliegende Ventilpartie eine Angriffsfläche für einen an der Entnahmeeinrichtung angeordneten Schwenkhebel bildet.The angled design of the valve device can preferably also be used in such a way that the valve section opposite the connection opening forms an engagement surface for a swivel lever arranged on the removal device.
Insgesamt erfüllt eine Anordnung gemäß der Erfindung die an sie aufgabengemäß'gestellten Forderungen dadurch, daß der Druckbehälter in seiner Einbaulage im Gerätegehäuse im wesentlichen senkrecht ausgerichtet angeordnet ist und in seinem oberen Bereich eine abgewinkelte Ventileinrichtung mit seitlich ausgerichteter Flanschöffnung aufweist, daß im Nahbereich der gegen den Ventilflansch gerichteten Anschlußöffnung der Gasentnahme-Einrichtung eine (nach oben geöffnete) Vorzentriervorrichtung für den Ventilflansch angeordnet ist und daß ein an der Gasentnahme-Einrichtung schwenkbar gelagerter Schwenkhebel-Verriegelungsmechanismus die Ventileinrichtung übergreifend an die Anschlußöffnung der Gasentnahme-Einrichtung gasdicht anlegt.Overall, an arrangement of the invention fulfills in accordance the requirements according to the object to it 'provided by the fact that the pressure vessel is arranged aligned in its installed position in the device housing substantially vertically and in its upper portion has an angled valve means with laterally oriented flange opening, that in the vicinity of the counter Valve flange directed connection opening of the gas sampling device a (upward open) pre-centering device for the valve flange is arranged and that a pivoting lever locking mechanism mounted pivotably on the gas sampling device makes the valve device gas-tight across the connection opening of the gas sampling device.
Eine nach diesen erfindungsgemäßen Merkmalen ausgestaltete Anordnung entspricht den an sie gestellten Aufgaben in vielerlei Hinsicht. Zum Einbau des Druckbehälters in das Gerät ist es in einem ersten Bedienungsgang lediglich erforderlich, den Druckbehälter im Bereich der abgekröpften Ventileinrichtung zu erfassen und mit dem Boden voran in eine Aufnahmekammer des Gerätes einzubringen. Durch die bevorzugterweise angeordneten Führungskulissen wird dabei der Gas-Druckbehälter in den Bereich seiner endgültigen Arbeitslage gebracht und im Bereich der abgewinkelten Ventileinrichtung durch die vor der Gasentnahme-Einrichtung angeordneten Vorzentriervorrichtung erfaßt. Nunmehr ist es lediglich nötig, durch Betätigung des Schwenkhebel-Verriegelungsmechanismus die Ventileinrichtung vollständig an die Gasentnahme-Einrichtung heranzuführen und die beiden Funktionsteile gasdicht miteinander zu verbinden. Der dabei auftretende Kraftfluß verläuft lediglich zwischen Gasentnahme-Einrichtung und Ventileinrichtung über den handbetätigbaren Schwenkhebel. Infolge der relativ kurzen zu überbrückenden Abstände kann auf elastische Anpreßmittel zum Toleranzausgleich weitestgehend verzichtet werden, so daß Beschädigungen im Flanschbereich sich mit großer Wahrscheinlichkeit dahin auswirken, daß dies beim Ansflanschvorgang durch erschwerte bzw. nicht durchführbare Betätigungsbedingungen erkennbar ist. Damit wird die Bedienungsperson auf fehlerhafte Bedingungen in den Flanschbereichen, welche sich auch als Verschmutzungen darstellen können, aufmerksam gemacht. Es ist aber zweckmäßig, die Andruckkraft selbst über ein kurzhubig wirkendes Federelement zu realisieren.An arrangement designed according to these features according to the invention corresponds to the tasks placed on it in many respects. To install the pressure vessel in the device, it is only necessary in a first operating step to grasp the pressure vessel in the region of the cranked valve device and to insert it with the bottom first into a receiving chamber of the device. Due to the preferably arranged guide links, the gas pressure container is brought into the area of its final working position and is detected in the area of the angled valve device by the pre-centering device arranged in front of the gas sampling device. Now it is only necessary to move the valve device completely towards the gas sampling device by actuating the swivel lever locking mechanism and to connect the two functional parts to one another in a gas-tight manner. The force flow that occurs only runs between the gas sampling device and the valve device via the manually operated pivoting lever. As a result of the relatively short distances to be bridged, elastic pressing means for tolerance compensation can largely be dispensed with, so that damage in the flange area has a high probability that this is recognizable during the flange-mounting process by difficult or not feasible operating conditions. This draws the operator's attention to faulty conditions in the flange areas, which can also present themselves as dirt. However, it is expedient to implement the pressing force itself via a spring element that acts with a short stroke.
Ist es erfindungsgemäß vorgesehen, den Gas-Druckbehälter in einer im wesentlichen senkrechten Lage im Gerätegehäuse anzuordnen, so ist die Gasentnahme-Einrichtung dahingehend bevorzugterweise auszugestalten, daß der Gewichtsschwerpunkt des Druckbehälters unterhalb der Zentriervorrichtung für den abgewinkelten Teil der Ventileinrichtung liegt. Damit wirkt sich die Gewichtskraft des Gas-Druckbehälters nicht verkantend auf die Flanschverbindung aus.If it is provided according to the invention to arrange the gas pressure container in a substantially vertical position in the device housing, the gas extraction device should preferably be designed in such a way that the center of gravity of the pressure container lies below the centering device for the angled part of the valve device. The weight of the gas pressure vessel does not have a canting effect on the flange connection.
Als zusätzliche Maßnahme zum Schutz der Flanschteile ist die erfindungsgemäße Anordnung bevorzugterweise dadurch gekennzeichnet, daß innerhalb eines Außenrohrstutzens im Bereich der Anschlußöffnung der Ventileinrichtung ein weiterer Zentrierrohrstutzen der Ventileinrichtung zum Anschluß an die Entnahmeeinrichtung angeordnet ist.As an additional measure to protect the flange parts, the arrangement according to the invention is preferably characterized in that a further centering pipe socket of the valve device for connection to the removal device is arranged within an outer pipe socket in the area of the connection opening of the valve device.
Ein nach den Merkmalen der ERfindung ausgestaltetes Ausführungsbeispiel ist anhand der Zeichnung im folgenden näher beschrieben. Es zeigen:
- Fig. 1 eine Seitenansicht einer Gasentnahme-Einrichtung in Verbindung mit einem an diese angeflanschten Gas-Druckbehälter in einem Geätegehäuse, teilweise geschnitten,
- Fig. 2 eine Draufsicht auf diese Anordnung in teilweiser Schnittdarstellung und
- Fig. 3 eine Ansicht in Richtung auf den Aufnahmeflansch der Gasentnahme- Einrichtung.
- 1 is a side view of a gas extraction device in connection with a gas pressure container flanged to it in a device housing, partly in section,
- Fig. 2 is a plan view of this arrangement in partial section and
- Fig. 3 is a view towards the receiving flange of the gas sampling device.
Die dargestellte Anordnung dient zur Entnahme von CO2-Gas aus einem Druckbehälter 1 über eine Gasentnahmne-Einrichtung 2 für einen Karbonisator eines Getränkeautomaten. In diesem Karbonisator wird Frischwasser mit dem COz -Gas angereichert.The arrangement shown serves for the removal of CO 2 gas from a
Die Gasentnahme-Einrichtung 2 enthält Regelglieder, welche in Verbindung mit einem Ventilstößel einer an dem Gas-Druckbehälter 1 angeordneten Ventileinrichtung 3 den innerhalb des Gasdruckbehälters 1 herrschenden Gasdruck auf den im Karbonisator benötigen Betriebsdruck geregelt reduzieren. Die Gasentnahme-Einrichtung 2 ist im Gerätegehäuse 4 befestigt und damit Bestandteil des Geräts. Der Gas-Druckbehälter 1 und die Ventileinrichtung 3 bilden eine Funktionseinheit, welche für die Versorgung des Karbonisators mit COZ -Gas an die Gasentnahme-Einrichtung 2 anzuflanschen ist.The
Zur Bedienungserleichterung und -vereinfachung ist zu diesem Zweck die Ventileinrichtung 3 gekröpft ausgebildet, d.h. ihr Anschlußflansch für die Gasentnahme-Einrichtung 2 ist gegenüber der Achse des Gasdruckbehälters 1 rechtwinklig abgewinkelt. Daraus ergibt sich für den Anschluß des Gasdruckbehälters 1 über die Ventilanordnung 3 an die Gasentnahme-Einrichtung 2 eine Anschlußbewegungsfolge in zwei Stufen. Ein neu in das Gerät einzubringender und anzuschließender Gas-Druckbehälter 1 wird durch die Gehäuseöffnung 5 mit seinem unteren Ende 6 voran in die Aufnahmekammer 7 für den Druckbehälter 1 im wesentlichen in Achsrichtung des Gas-Druckbehälters 1 eingeführt. Geführt durch die Wandabschnitte 8, 9 wird dabei der Gas-Druckbehälter 1 um die Rundkante 10 innerhalb des Gerätegehäuses 4 zwangsläufig in eine Lage verschwenkt und gebracht, bei de die Ventilanordnung 3 in den Bereich der Gasentnahme-Einrichtung 2 gelangt.To facilitate and simplify operation, the
Dieser Gasentnahme-Einrichtung 2 vorgelagert ist eine Zentriervorrichtung 11, über welches das abgewinkelte Teilstück der Ventilvorrichtung 3 erfaßt wird, so daß der Anschlußflansch der Ventileinrichtung 3 mit dem komplementären Anschlußflansch der Gasentnahme-Einrichtung 2 zentriert wird. Zu diesem Zweck ist die der Gasentnahme-Vorrichtung 2 vorgelagerte Zentriervorrichtung 11 - wie in Fig. 3 dargestellt - nach oben hin offen U-förmig ausgestaltet, so daß sie beim Einschieben des Gas-Druckbehälters 1 den abgekröpften, in Fig. 3 strichpunktiert angedeuteten Keil 12 der Ventileinrichtung erfaßt, bis dieser am Boden dieser Zentriereinrichtung 11 zur Anlage kommt. Die Einbaulage des Gas-Druckbehälters 1 ist so gewählt, daß dessen Schwerpunkt dabei im wesentlichen unterhalb dieses Auflagepunkts zwischen Zentriervorrichtung 11 und abgekröpften Teil 12 de Ventileinrichtung liegt. Diese vorzentrierte Arbeitslage ist also im wesentlichen stabil.Upstream of this
Aus dieser Arbeitslage ist die gasdichte Verbindung zwischen den Flanschteilen der Ventileinrichtung 3 und der Gasentnahme-Einrichtung 2 herbeizuführen. Dazu dient ein handbetätigbarer Schwenkhebel 13, welcher auf Achsansätzen 14 der Gasentnahme-Einrichtung 2 schwenkbar gelagert ist. In den Figuren 1 und 3 ist die Arbeitslage des Schwenkhebels 13 dargestellt. Dieser greift über angeschrägte Betätigungsflächen 15 an Betätigungsansätzen 16 der Ventileinrichtung 3 an. Durch die von oben herab durchgeführte Schwenkbewegung des handbetätigten Schwenkhebels 13. werden dabei die korrespondierenden Flanschteile der Ventileinrichtung 3 und der Gasentnahme-Einrichtung 2 axial zusammengefügt. Der endgültige Anpreßdruck für diese Funktionsteile wird durch ein im Schwenkhebel 13 angeordnetes Federelement 17 ausgeübt, welches über einen Druckbolzen 18 auf die dem Anschlußflansch der Ventileinrichtung 3 gegenüberliegende Ventilpartie auf die Ventileinrichtung 3 wirkt. In dieser Stellung wird über diesen Bolzen 18 der Schwenkhebel 13 hinter einer Erhöhung der Ventileinrichtung 3 auch kraftschlüssig verrastet.The gas-tight connection between the flange parts of the
