Description

Die Erfindung betrifft eine Ventilanordnung für Behälter zur Herstellung, Behandlung und/oder Aufbewahrung von Flüssigkeiten, insbesondere von Wein.The invention relates to a valve assembly for containers for the production, treatment and / or storage of liquids, especially wine.

Bei der Herstellung und Lagerung von Wein und anderen Lebensmitteln wie Fruchtsäften, Milch, Destillaten, Likören, sogar Medikamenten, wie z.B. lnfusionslösungen, Essig, Ölen, in Öl eingelegten Oliven, biologischem Material, das eventuell von Bakterien oder anderen Mikroorganismen befallen werden kann, und dergleichen mehr in Behältern können Druckschwankungen auftreten. Bekannt sind beispielsweise Hochdrucktanks, in denen Prozesse im Druckbereich von mehreren bar stattfinden können. Diese Behälter weisen eine vergleichsweise große Wandstärke auf, um den hohen Drücken widerstehen zu können, und sind entsprechend kostspielig. Es gibt jedoch auch Anwendungen, bei denen bisher druckfrei, d.h. mit Atmosphärendruck gearbeitet wurde. Bei solchen Anwendungen, beispielsweise bei der Weinherstellung, sind Tanks, insbesondere Edelstahltanks üblich, die eine sehr geringe Wandstärke von weniger als 1 mm aufweisen und entsprechend weniger materialaufwendig sind. Diese Tanks sind jedoch gegen Überdruck und Unterdruck empfindlich. Bei Überschreitung eines gewissen Überdrucks kann der Tank bersten. Bei Unterschreitung schon eines geringen Unterdrucks kann der Tank kollabieren. Im Verlauf der Weinherstellung treten durch den Gärprozess natürliche Druckschwankungen auf. Bisher ist eine sogenannte offene Gärung vorgenommen worden. Dabei steht der Tank über eine kleine Öffnung mit der Atmosphäre in Verbindung. Die Problematik hierbei ist, dass einerseits Fremdstoffe in den Tank hineingelangen können und dass andererseits wichtige Komponenten aus dem Wein entweichen können. Solche Komponenten sind insbesondere Aromastoffe und CO2. Einerseits soll überschüssiges, bei der Fermentation entstehendes CO2 austragen werden, andererseits sollen die Aromastoffe im Wein verbleiben. Eine kontrollierte Austragung des CO2 ist mit den bekannten, offenen Systemen nicht möglich. Bei der Verwendung von Hochdrucktanks bei der Weinherstellung kann es andererseits zu Gärstörungen durch zu hohen Überdruck kommen.In the production and storage of wine and other foodstuffs such as fruit juices, milk, distillates, liqueurs, even medicines such as infusion solutions, vinegar, oils, olives in oil, biological material that may be infested by bacteria or other microorganisms, and such more in containers, pressure fluctuations may occur. For example, high-pressure tanks are known in which processes in the pressure range of several bar can take place. These containers have a comparatively large wall thickness in order to withstand the high pressures, and are correspondingly expensive. However, there are also applications in which previously worked without pressure, ie at atmospheric pressure. In such applications, for example in the winemaking, tanks, especially stainless steel tanks are common, which have a very small wall thickness of less than 1 mm and are correspondingly less material consuming. However, these tanks are sensitive to overpressure and negative pressure. If a certain overpressure is exceeded, the tank may burst. If the pressure falls below a slight negative pressure, the tank may collapse. In the course of wine production occur through the fermentation natural pressure fluctuations. So far, a so-called open fermentation has been made. The tank is connected to the atmosphere via a small opening. The problem here is that on the one hand foreign substances can get into the tank and on the other hand important components can escape from the wine. Such components are, in particular, flavorings and CO 2 . On the one hand, excess CO 2 produced during fermentation should be discharged, on the other hand the flavors should remain in the wine. A controlled discharge of CO 2 is not possible with the known, open systems. On the other hand, when using high-pressure tanks in winemaking, fermentation disturbances can occur due to excessive overpressure.

Ein kombiniertes Über- und Unterdruckventil für Kraftstofflagertanks ist aus der US 2004/0112437 A1 bekannt. Da beide Ventilfunktionen in einem gemeinsamen Gehäuse angeordnet sind, können nicht unterschiedliche Über- und Unterdruckventile miteinander kombiniert werden. Ein Unterdruckventil für hohe Flussraten ist aus der GB 735 054 A bekannt. Dieses weist jedoch einen sehr großen Ventilkörperdurchmesser auf und ist daher zur Verwendung in einer Ventilanordnung der eingangs genannten Art nicht geeignet.A combined pressure and vacuum valve for fuel storage tanks is from the US 2004/0112437 A1 known. Since both valve functions are arranged in a common housing, not different pressure and vacuum valves can be combined. A vacuum valve for high flow rates is from the GB 735 054 A known. However, this has a very large valve body diameter and is therefore not suitable for use in a valve arrangement of the type mentioned.

Ausgehend hiervon sollen eine Anordnung und ein Verfahren bereitgestellt werden, die eine möglichst schonende, Aroma bewahrende Herstellung des Weins bzw. anderer wichtiger Eigenschaften der behandelten Flüssigkeit möglich machen. Weiterhin soll ein Schutz gegen unerwünschte Oxidation des Behälterinhalts ermöglicht werden und eine kontrollierte Imprägnierung z.B. mit CO2 stattfinden können. Schließlich soll ein energiesparender Herstellungs- oder Lagerprozess ermöglicht werden, etwa durch eine Stromeinsparung durch verminderten Einsatz oder Wegfall von Kühlaggregaten. Schließlich soll der CO2-Verbrauch bei der Vinifizierung vermindert werden.On the basis of this, an arrangement and a method are to be provided which make possible the most gentle, flavor-preserving production of the wine or other important properties of the treated liquid. Further, a protection against undesirable oxidation of the container contents will be facilitated and may take place in a controlled impregnation, for example with CO 2. Finally, an energy-saving manufacturing or storage process is to be made possible, for example by a power savings through reduced use or elimination of cooling units. Finally, the CO 2 consumption in the vinification should be reduced.

Zur Lösung dieser Aufgabe wird ein Niederdruckprozess vorgeschlagen, der durch den Einsatz eines an einem höchsten Punkt eines Behälters anschließbaren Rohrsystems und eines Überdruckventils mit einem Öffnungsdruck von weniger als 1 bar, das über das Rohrsystem mit dem Behälterinnenraum kommuniziert, wobei das Überdruckventil als federbelastetes Sitzventil mit einem durch Verändern der Federvorspannung einstellbaren Öffnungsdruck im Bereich von 0,05 bis 1 bar ausgebildet ist und wobei ein an dem Rohrsystem parallel zu dem Überdruckventil angeordnetes Unterdruckventil mit einem Öffnungsdruck von weniger als 0,007 bar vorgesehen ist. Bei diesen Drücken werden empfindliche, dünnwandige Edelstahlbehälter nicht beschädigt. Dabei ist berücksichtigt, dass derartige Edelstahlbehälter wesentlich empfindlicher gegenüber einem Unterdruck als gegenüber einem Überdruck sind. Im Gegensatz hierzu wird bei den bekannten Hochdruckprozessen im Druckbereich beispielsweise von 4 bis 7 bar gearbeitet. Derartige Anlagen fallen unter die Druckbehälterverordnung und sind somit prüfpflichtig, was zu höheren Betriebskosten beiträgt.To solve this problem, a low-pressure process is proposed, which communicates through the use of a connectable to a highest point of a container pipe system and a pressure relief valve with an opening pressure of less than 1, which communicates via the pipe system with the container interior, wherein the pressure relief valve as a spring-loaded seat valve an adjustable by changing the spring preload opening pressure in the range of 0.05 to 1 bar is formed and wherein a parallel to the pressure relief valve disposed on the pipe system vacuum valve is provided with an opening pressure of less than 0.007 bar. These pressures are sensitive, thin-walled stainless steel container not damaged. It is considered that such stainless steel containers are much more sensitive to a vacuum than to overpressure. In contrast, in the known high-pressure processes in the pressure range, for example, from 4 to 7 bar worked. Such systems fall under the pressure vessel regulation and are therefore subject to testing, which contributes to higher operating costs.

Das Rohrsystem für die Ventile wird im Bereich des höchsten Punkts des Behälters angeschlossen, um sicherzustellen, dass eine Verbindung zum Gasraum über dem Inhalt, nicht jedoch mit dem Inhalt selbst, besteht. Dem Überdruckventil ist ein Manometer mit einer von 0 bis 0,5 bar reichenden Skala zugeordnet. Das Überdruckventil ist ein federbelastetes Sitzventil. Die Federvorspannung, die für die Höhe des Öffnungsdrucks des Ventils bestimmend ist, lässt sich vorteilhafterweise über eine Gewindehülse einstellen. Besonders vorteilhaft ist es, wenn der untere Bereich des Ventils, wo beim Öffnen des Ventils Gas aus dem Behälter ausströmt, von einem Flüssigkeitsreservoir, beispielsweise einem Standzylinder aus vorzugsweise transparentem Material, umgeben ist. Bevorzugt besteht der Standzylinder aus Glas oder Acrylglas. Der Zylinder begrenzt einen nach oben offenen Ringraum, der mit einer Flüssigkeit gefüllt werden kann. Der Zylinder ist an einem Flansch, der den Boden des Reservoirs bildet, mittels eines O-Rings dichtend aufgeklemmt. Im unteren Bereich des Ventilgehäuses ist mindestens eine Öffnung vorgesehen, die zum Innenbereich des Ventils oberhalb vom Ventilsitz führt. Diese Zutrittsöffnung sollte von einem eingefüllten Flüssigkeitsstand überdeckt werden. Die bei Überdruck entweichenden Gase treten durch die Flüssigkeit aus. Die hierbei entstehenden Blasen sind zum einen optisch wahrnehmbar, zum anderen tritt ein Gluckergeräusch auf, das akustisch wahrnehmbar ist. Das Austreten von Gasen aus dem Behälter wird somit auf einfache Weise und auch aus einiger Entfernung - bei größeren Behältern etlichen Metern - optisch und akustisch signalisiert. Bei Verwendung einer geeigneten Flüssigkeit kann eine chemische Reaktion mit einer Indikatorwirkung auftreten. Die verwendete Flüssigkeit tritt selbstverständlich auch in den Innenraum des Ventilgehäuses ein und umgibt den Ventilkörper. Die Flüssigkeit kann dennoch nicht über das Ventil in den Innenraum des Tanks eintreten, da der Ventilsitz einen Kegelsitz aufweist, der nur bei entsprechendem Überdruck öffnet und das ausströmende Gas verhindert dann ein Eintreten der Flüssigkeit.The pipe system for the valves is connected in the area of the highest point of the vessel to ensure that there is a connection to the headspace over the contents, but not the contents themselves. The pressure relief valve is assigned a pressure gauge with a scale ranging from 0 to 0.5 bar scale. The pressure relief valve is a spring-loaded seat valve. The spring preload, which determines the height of the opening pressure of the valve, can advantageously be adjusted via a threaded sleeve. It is particularly advantageous if the lower region of the valve, where gas flows out of the container when the valve is opened, is surrounded by a liquid reservoir, for example a stationary cylinder of preferably transparent material. The stand cylinder is preferably made of glass or acrylic glass. The cylinder defines an upwardly open annulus, which can be filled with a liquid. The cylinder is sealingly clamped to a flange which forms the bottom of the reservoir by means of an O-ring. In the lower region of the valve housing, at least one opening is provided, which leads to the inner region of the valve above the valve seat. This access opening should be covered by a filled liquid level. The escaping at excess pressure gases escape through the liquid. The resulting bubbles are on the one hand visually perceptible, on the other hand, a clucking noise occurs, which is acoustically perceptible. The escape of gases from the container is thus in a simple manner and also from a distance - for larger containers several meters - visually and acoustically signaled. When using a suitable liquid, a chemical reaction with an indicator effect may occur. Of course, the liquid used also enters the interior of the valve housing and surrounds the valve body. Nevertheless, the liquid can not enter the interior of the tank via the valve since the valve seat has a conical seat which only opens when the pressure is correspondingly high, and the outflowing gas then prevents the liquid from entering.

Das Ventil weist weiterhin einen Betätigungsknopf auf, der direkt mit dem Ventilkörper verbunden ist und von außen durch Anheben eine manuelle Druckentspannung des Tanks ermöglicht. Eine manuelle Druckentspannung wird beispielsweise dann durchgeführt, wenn der Tank geöffnet werden soll, da er dann druckfrei sein sollte. Mittels dem Manometer lässt sich überwachen, wann der Druckausgleich stattgefunden hat.The valve further comprises an actuating button, which is directly connected to the valve body and from the outside by lifting a manual pressure release of the tank allows. A manual pressure release is performed, for example, when the tank is to be opened, since it should then be pressure-free. By means of the manometer can be monitored when the pressure equalization has taken place.

Die das Überdruckventil umfassende Armatur kann noch einen Absperrhahn aufweisen. Dieser ist bevorzugt als Kugelventil bzw. Kugelhahn ausgebildet. Über diesen Hahn kann der Tank mit CO2 beaufschlagt werden. Es können auch flüssige Zusätze in den Tank geleitet werden. Weiterhin lässt sich ein Füllstandsanzeiger anschließen.The valve comprising the pressure relief valve may still have a shut-off valve. This is preferably designed as a ball valve or ball valve. The tank can be charged with CO 2 via this tap. It is also possible to pass liquid additives into the tank. Furthermore, a level indicator can be connected.

Das neben dem Überdruckventil vorgesehene Unterdruckventil weist einen Öffnungsdruck von etwa 0,005 bar auf. Dieses sehr geringe Unterdruckniveau ist als Obergrenze angesetzt, um Druckbeschädigungen des Tanks zu verhindern. Ein solch geringer zulässiger Unterdruck ist jedoch bereits ausreichend, da ein Unterdruck an sich den Gärprozess oder ähnliche Prozesse nicht vorteilhaft unterstützt. Die Unterdrucksteuerung soll lediglich Ausdehnungs- und Kontraktionsvorgänge bei Temperaturschwankungen oder Luftdruckschwankungen ausgleichen. Wichtig ist insbesondere bei der Entnahme von Flüssigkeit aus dem Tank, dass eine Belüftung gewährleistet ist, die bevorzugt durch die Verwendung des Unterdruckventils automatisch erfolgt. Bekannt war bisher, einen manuell zu betätigenden Absperrmechanismus auf der Oberseite des Tanks vorzusehen, der jedoch vor einem Entleeren bzw. einer Entnahme der Flüssigkeit aus dem Tank geöffnet werden musste. Falls die Herstellung dieses Druckausgleichs unterblieb, so wird durch die ausströmende Flüssigkeit sehr schnell ein Unterdruckniveau erzeugt, das in der Vergangenheit zu einem Kollabieren des Tanks geführt hat. Das Unterdruckventil weist einen Ventilstößel auf, der oben durch eine auf das Ventilgehäuse aufgesetzte Silikonkappe gegen Eintreten von Schmutzpartikein abgedichtet ist.The provided next to the pressure relief valve vacuum valve has an opening pressure of about 0.005 bar. This very low level of vacuum is used as an upper limit to prevent pressure damage to the tank. However, such a low allowable negative pressure is already sufficient, since a negative pressure per se does not favorably support the fermentation process or similar processes. The vacuum control is only intended to compensate for expansion and contraction during temperature fluctuations or air pressure fluctuations. It is particularly important when removing liquid from the tank, that a ventilation is ensured, which is preferably done automatically by the use of the vacuum valve. It was previously known to provide a manually operated shut-off mechanism on the top of the tank, which, however, had to be opened before emptying or removal of the liquid from the tank. If the production of this pressure equalization was omitted, then a low pressure level is generated very quickly by the outflowing liquid the past has led to a collapse of the tank. The vacuum valve has a valve stem which is sealed at the top by a silicone cap attached to the valve housing to prevent dirt particles from entering.

Das Unterdruckventil ist bevorzugt über einen Flanschanschluss starr mit dem Tank verbunden. Der Überdruckteil der Armatur ist über eine verstellbare Gewindeverbindung mit dem Unterdruckteil verbunden. Hierdurch lässt sich die Neigung des Überdruckteils variieren, so dass eine Bedienperson das Manometer und die Funktion des Überdruckventils aus einer bodennahen Position leicht optisch überwachen kann. Dies ist insbesondere bei großen Tanks von Interesse, die Höhen von mehreren Metern aufweisen können.The vacuum valve is preferably rigidly connected to the tank via a flange connection. The overpressure part of the valve is adjustable Threaded connection connected to the vacuum part. In this way, the inclination of the overpressure part can be varied so that an operator can easily optically monitor the pressure gauge and the function of the overpressure valve from a ground-level position. This is of particular interest for large tanks, which may have heights of several meters.

Grundsätzlich ist die Anwendung des erfindungsgemäßen Ventilsystems nicht auf große Tanks beschränkt. Das Einsatzgebiet reicht von Kleintanks oder Kleinsttanks mit Volumina im Bereich von 100 Liter bis zu Großtanks mit Füllmengen im Bereich von 1 Mio. Liter. Die dargestellte Ausführung deckt sämtliche Einsatzzwecke ab, d.h. die Ventileinrichtung skaliert nicht mit der Tankgröße. Das Überdruckventil lässt sich bis zu einer Ausströmmenge von etwa 30.000 I/h verwenden.Basically, the application of the valve system according to the invention is not limited to large tanks. The field of application ranges from small tanks or small tanks with volumes in the range of 100 liters to large tanks with capacities in the range of 1 million liters. The illustrated embodiment covers all purposes, i. the valve device does not scale with the tank size. The pressure relief valve can be used up to a discharge rate of about 30,000 l / h.

In the following the invention will be explained in more detail with reference to an embodiment shown schematically in the drawing. It shows

Die in der Zeichnung dargestellte Ventilanordnung besteht im Wesentlichen aus einem drei T-Stücke 10, 12, 14 umfassenden Rohrsystem, das ein Unterdruckventil 16 und ein Überdruckventil 18 mit der Oberseite eines nicht näher dargestellten Behälters verbindet. Das T-Stück 10 weist einen Kegelstutzen 20 auf, der mittels der Nutmutter 22 an einem entsprechenden Gegenstück am Behälter befestigt wird. Auf gleiche Weise sind die T-Stücke 10 und 12 miteinander verbunden, so dass das T-Stück 12 gegenüber dem T-Stück 10 verschwenkt werden kann, beispielsweise um das Manometer 24, das einen Überdruck im Behälter anzeigt, aus einer bestimmten Position besser ablesen zu können. Am freien Ende des T-Stücks 14 ist ein Kugelhahn 26 angeordnet, der geöffnet werden kann, um den Behälter über einen Schlauch 28 beispielsweise mit CO2-Gas zu beaufschlagen.The valve assembly shown in the drawing consists essentially of a three tees 10, 12, 14 comprising a pipe system that connects a vacuum valve 16 and a pressure relief valve 18 to the top of a container, not shown. The T-piece 10 has a conical socket 20 which is fastened by means of the nut 22 to a corresponding counterpart on the container. Similarly, the T-pieces 10 and 12 are connected to each other, so that the T-piece 12 can be pivoted relative to the T-piece 10, for example, the pressure gauge 24, which indicates an overpressure in the container to be able to read better from a certain position. At the free end of the T-piece 14, a ball valve 26 is arranged, which can be opened to pressurize the container via a hose 28, for example, with CO 2 gas.

Das Überdruckventil 18 ist in Fig. 2 näher dargestellt. Das Ventil 18 ist als Sitzventil ausgebildet, mit einem Kegelventilkörper 30, der mittels einer Feder 32 gegen einen Ventilsitz im Gehäuse des Ventils 18 gedrückt wird. Die Vorspannung der Feder 32 und damit der Überdruck, bei dem das Ventil öffnet, kann über einen Gewindedeckel 34 verändert werden. Im Bereich des Ventilkörpers 30 weist das Ventilgehäuse eine Reihe von Durchbrechungen 36 auf, über die Gas beim Öffnen des Ventils ausströmen kann. Die Durchbrechungen 36 sind von einem Flüssigkeitsreservoir umgeben, dass durch einen Flanschboden 38 und einen Acrylglaszylinder 40 gebildet ist. Ein in einer Umfangsnut des Flanschbodens 38 angeordneter O-Ring 42 sorgt für einen kraftschlüssigen und flüssigkeitsdichten Sitz des Zylinders 40 auf dem Flanschboden 38. Beim Austreten von Gas aus dem Behälter strömt dieses durch die in dem Reservoir vorhandene Flüssigkeit und zeigt das Austreten optisch durch Blasenbildung und akustisch durch Gluckergeräusche an. Ein Kugelgriff 44 ist über eine Stange 46 mit dem Ventilkörper 30 verbunden und erlaubt durch Anheben eine manuelle Druckentspannung des Behälters.The pressure relief valve 18 is in Fig. 2 shown in more detail. The valve 18 is designed as a seat valve, with a cone valve body 30 which is pressed by means of a spring 32 against a valve seat in the housing of the valve 18. The bias of the spring 32 and thus the overpressure at which the valve opens, can be changed via a threaded cover 34. In the region of the valve body 30, the valve housing has a number of openings 36 through which gas can flow when opening the valve. The openings 36 are surrounded by a liquid reservoir that is formed by a flange bottom 38 and an acrylic glass cylinder 40. An O-ring 42 arranged in a circumferential groove of the flange bottom 38 ensures a frictional and liquid-tight fit of the cylinder 40 on the flange bottom 38. When gas escapes from the container, it flows through the liquid present in the reservoir and visually shows the escape by blistering and acoustically by clucking sounds. A ball handle 44 is connected via a rod 46 to the valve body 30 and allows by lifting a manual pressure release of the container.
