Description
Die vorliegende Erfindung betrifft einen Zugregler mit einer öffenbaren Regelklappe als druckdifferenzabhängig wirksames Verschlusselement einer Nebenlufteinlassöffnung einer Abgasleitung, so dass abhängig von der im Bereich der Nebenlufteinlassöffnung herrschenden Differenz zwischen dem Druck im Außenraum und dem Druck im Innenraum der Abgasleitung die Öffnungsweite der Nebenlufteinlassöffnung änderbar ist, wobei der Zugregler eine Außenraumseite aufweist, die in eingebautem Zustand des Zugreglers dem Außenraum der Abgasleitung zugewandt ist, wobei eine an der Außenraumseite angeordnete Abdeckung für die Regelklappe vorhanden ist.The present invention relates to a draft regulator with an openable control flap as a pressure difference-dependent effective closure element of a secondary air inlet opening of an exhaust pipe, so that depending on the prevailing in the region of the secondary air inlet opening difference between the pressure in the outer space and the pressure in the interior of the exhaust pipe, the opening width of the secondary air inlet opening is changeable the draft regulator has an outside space side which, in the installed state of the draft regulator, faces the outside space of the exhaust gas line, a cover for the control flap arranged on the outside being present.
Zugregler der hier betrachteten Art sind in diversen Ausgestaltungen bekannt und in Abgasanlagen von Gebäudeheizungen weit verbreitet im Einsatz. Sie werden auch als Zugbegrenzer und als Nebenluftvorrichtungen bezeichnet.Tension regulators of the type considered here are known in various embodiments and widely used in exhaust systems of building heaters in use. They are also referred to as Zugbegrenzer and as secondary air devices.
Zugregler dienen dazu, den Zug in einem Kamin oder Schornstein bei Brennbetrieb einer daran angeschlossenen Feuerstätte im Wesentlichen konstant zu halten bzw. für eine ständige Druckanpassung in der Abgasstrecke bei sich ändernden Betriebsbedingungen der Feuerstätte oder bei schwankenden Witterungseinflüssen, wie Außentemperatur, Wind, usw. zu sorgen. Die vom Zugregler vorgenommene Druckanpassung erfolgt durch Beimischung von Nebenluft in die Abgasanlage.Tension regulators serve to keep the train in a chimney or chimney during firing operation of a connected fireplace essentially constant or for a constant pressure adjustment in the exhaust gas line at changing operating conditions of the fireplace or in fluctuating weather conditions, such as outside temperature, wind, etc. to care. The pressure adjustment made by the draft regulator is done by adding secondary air into the exhaust system.
Ein konventioneller Zugregler hat ein topfförmiges Gehäuse, welches mit seiner offenen Stirnseite an einer betreffenden Abgasleitung angeschlossen ist, so dass der Innenraum des topfförmigen Gehäuses zum Innenraum der Abgasleitung hin offen ist, wobei die Verbindungsstelle zwischen Zugreglergehäuse und Abgasleitung jedoch nach außen dicht ist. An der außen liegenden Stirnseite des Zugreglergehäuses befindet sich die Nebenlufteinlassöffnung sowie die pendelnd bzw. schwenkbar um eine horizontale Achse gelagerte Regelklappe, welche in ihrer Schließstellung die Nebenlufteinlassöffnung mit Randüberlapp verschließt. In dieser Schließstellung der Regelklappe strömt dann keine Nebenluft vom Außenraum durch die Nebenlufteinlassöffnung hindurch in den Innenraum der Abgasleitung bzw. in den Innenraum des daran angeschlossenen Zugreglergehäuses.A conventional draft regulator has a pot-shaped housing, which is connected with its open end to a respective exhaust pipe, so that the interior of the cup-shaped housing to the interior of the exhaust pipe is open, the junction between Zugreglergehäuse and the exhaust pipe is sealed to the outside. On the outer end side of the Zugreglergehäuses is the secondary air inlet opening and the control flap, which is mounted in a swinging or pivoting manner about a horizontal axis and which in its closed position closes the secondary air inlet opening with edge overlap. In this closed position of the control flap then no secondary air flows from the outside space through the secondary air inlet opening into the interior of the exhaust pipe or into the interior of the Zugreglergehäuses connected thereto.
Sinkt der Druck im Innenraum gegenüber dem Druck im Außenraum bzw. an der Außenseite des Zugreglergehäuses, so wird die Regelklappe nach Maßgabe der Druckdifferenz aus ihrer Schließstellung heraus in eine Öffnungsstellung übergehen. Je nach Öffnungsstellung der Regelklappe ist die Nebenlufteinlassöffnung mehr oder weniger weit geöffnet, so dass eine mehr oder weniger große Nebenluftmenge in die Abgasleitung einströmen kann. Steigt der Druck in der Abgasleitung relativ zum Außendruck an der Regelklappe wieder an, so kann die Regelklappe um ihre Schwenkachse herum in die Schließstellung zurückkippen.If the pressure in the interior decreases in relation to the pressure in the outer space or on the outer side of the tension regulator housing, the control flap will change from its closed position to an open position in accordance with the pressure difference. Depending on the open position of the control flap, the secondary air inlet opening is more or less wide open, so that a more or less large amount of secondary air can flow into the exhaust pipe. If the pressure in the exhaust pipe increases again relative to the external pressure at the control flap, the control flap can tilt back about its pivot axis into the closed position.
Bekannte Zugregler werden in einem gesonderten Raum eines Gebäudes zentral an die Abgasleitung angeschlossen. Ein solcher Raum ist insbesondere der Heizungskeller des Gebäudes, in dem auch die Feuerstätte der (Zentral-) Heizung aufgestellt ist. Der Zutritt zu diesem Raum ist üblicherweise nur bestimmten Personen gestattet, die entsprechende Sachkenntnisse über die Funktions- und Einstellweise des Zugreglers besitzen.Known draft regulators are connected in a separate room of a building centrally to the exhaust pipe. Such a room is in particular the boiler room of the building in which also the fireplace of the (central) heating is installed. Access to this room is usually only allowed to certain persons who have the necessary expertise in the function and adjustment of the tension controller.
Aus der gattungsbildenden
Derartige Zugregler gewährleisten, dass ein Hantieren an der Regelklappe durch nichtautorisierte Personen, die keine genügende Sachkenntnis über den Zugregler besitzen, verhindert wird. Dadurch kann ein Zugregler auch dann an eine Abgasleitung angeschlossen werden, wenn ein gesonderter Raum für den Zugregler im Gebäude nicht vorhanden ist. Der Zugregler kann beispielsweise in einem Raum installiert sein, der für die Bewohner des Gebäudes frei zugänglich ist. In demjenigen Fall, in dem sich eine zentrale Feuerstätte im Gebäude befindet, ist es insbesondere nicht notwendig, den erfindungsgemäßen Zugregler in dem Raum der zentralen Feuerstätte vorzusehen. Des Weiteren ist ein Einsatz eines Zugreglers auch dann möglich, wenn keine zentrale Feuerstätte im Gebäude vorhanden ist, sondern mehrere (Einzel-) Feuerstätten auf verschiedene Räume im Gebäude verteilt und an einer gemeinsamen Abgasleitung bzw. an einem gemeinsamen Kamin angeschlossen sind.Such draft regulators ensure that manipulation of the control damper by unauthorized persons who do not possess sufficient knowledge of the draft regulator is prevented. This allows a draft regulator to be connected to an exhaust pipe even if a separate room for the draft regulator in the building is not available. For example, the draft regulator may be installed in a room that is freely accessible to the occupants of the building. In particular, in the case in which a central fireplace is in the building, it is not necessary to provide the draft regulator according to the invention in the space of the central fireplace. Furthermore, a use of a draft regulator is also possible if no central fireplace in the building is present, but several (single) fireplaces distributed to different rooms in the building and connected to a common exhaust pipe or to a common fireplace.
Weiterhin kann aufgrund der Abdeckung der Regelklappe ein verbesserter Schutz gegen einen Austritt von Flugasche und Rauchgasrückständen erreicht werden. Ein Herausfallen von Rückständen, insbesondere von brennenden Rückständen z. B. bei einem Kaminbrand, ist somit nicht möglich.Furthermore, an improved protection against leakage of fly ash and flue gas residues can be achieved due to the cover of the butterfly valve. Falling out of residues, especially burning residues z. B. in a fire, so it is not possible.
Die Aufgabe der vorliegenden Erfindung liegt nun darin, die Einsatzmöglichkeit eines Zugreglers der eingangs genannten Art zu erweitern.The object of the present invention is now to expand the possibility of using a draft regulator of the type mentioned.
Diese Aufgabe wird erfindungsgemäß gelöst, indem eine Zuluftleitung zum Zuführen von Luft in das Innere der Abdeckung vorgesehen ist. Diese Zuluftleitung führt vorzugsweise zu einem anderen Raum, als demjenigen, in dem der Zugregler angebracht ist. Aus diesem anderen Raum kann dann Luft dem Zugregler und damit der Abgasleitung zugeführt werden. Die Einsatzmöglichkeit des erfindungsgemäßen Zugreglers wird damit vergrößert. Insbesondere bei luftdichten Räumen, bei einem Betrieb einer kontrollierten Raumlüftung, bei einem Betrieb einer Wärmepumpe oder eines Gebläses, wie beispielsweise einer Dunstabzughaube, im Raum des Zugreglers erfolgt dann die Luftzutuhr zur Regelklappe unabhängig von den Luftbedingungen im Raum des Zugreglers. Die Zuluftleitung kann auch zusätzlich zu Öffnungen in der Abdeckung vorgesehen sein.This object is achieved according to the invention by providing a supply air duct for supplying air into the interior of the cover. This supply air duct preferably leads to a different space than the one in which the draft regulator is mounted. From this other room then air can be fed to the draft regulator and thus the exhaust pipe. The possible use of the invention Zugreglers is increased with it. Especially in airtight rooms, in an operation of a controlled room ventilation, when operating a heat pump or a blower, such as a fume hood, in the room of Zugreglers then the Luftzutuhr to the control valve is independent of the air conditions in the room of the Zugreglers. The supply air line may also be provided in addition to openings in the cover.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung weist die Abdeckung eine solche Größe und Form auf, dass die Regelklappe durch die Abdeckung vollständig abgedeckt ist. Dadurch ist eine besonders große Sicherheit gegen Beschädigung oder unsachgemäße Verstellung der Regelklappe gegeben.According to an advantageous embodiment of the invention, the cover has such a size and shape that the control flap is completely covered by the cover. As a result, a particularly high level of security against damage or improper adjustment of the control flap is given.
In einer weiteren bevorzugten Ausführungsform des erfindungsgemäßen Zugreglers ist ein Einstellelement zum Einstellen des Öffnungsverhaltens der Regelklappe vorhanden. Durch dieses Einstellelement kann ein Mindest-Zugbedarf der an die Abgasleitung angeschlossenen Feuerstätte(n) eingestellt werden. Dieses Einstellelement ist von der Abdeckung abgedeckt. Das Einstellelement ist somit, wie die Regelklappe, durch die Abdeckung vor Beschädigung oder unsachgemäßer Verstellung geschützt.In a further preferred embodiment of the draft regulator according to the invention, an adjusting element for adjusting the opening behavior of the control flap is present. By means of this adjustment element, a minimum draft requirement of the fireplace (s) connected to the exhaust pipe can be set. This adjustment is covered by the cover. The adjusting element is thus, like the control flap, protected by the cover from damage or improper adjustment.
Vorteilhafterweise ist die Abdeckung aus einem formstabilen Material gebildet. Dies gewährleistet einen besonders guten Schutz der Regelklappe. Ein einfaches Verbiegen der Abdeckung wird verhindert. Die Abdeckung kann insbesondere kasten- oder topfförmig ausgestaltet sein.Advantageously, the cover is formed of a dimensionally stable material. This ensures a particularly good protection of the butterfly valve. A simple bending of the cover is prevented. The cover may be designed in particular box or cup-shaped.
In einer besonders bevorzugten Ausgestaltung ist die Abdeckung öffenbar oder demontierbar. Dadurch wird bedarfsweise ein Zugang zum Innern des Zugreglers gewährleistet, beispielsweise um diesen zu reinigen oder um die Einstellung eines hinter der Abdeckung verborgenen Einstellelementes zu verändern. Vorteilhafterweise ist dann ein Schließelement zum Abschließen der Abdeckung vorhanden, um ein Öffnen oder Demontieren durch Unbefugte sicherheitshalber auszuschließen.In a particularly preferred embodiment, the cover can be opened or removed. As a result, if necessary, access to the interior of the tension controller is ensured, for example, to clean it or to change the setting of a concealed behind the cover adjustment. Advantageously, then there is a closing element for closing the cover to an opening or dismantling by unauthorized persons for safety's sake.
Die Abdeckung weist vorteilhafterweise Öffnungen, insbesondere ein Lochgitter, auf. Somit kann auf technisch einfache und effektive Weise eine ausreichende Luftzufuhr durch die Abdeckung zur Regelklappe und damit zur Abgasleitung ermöglicht werden.The cover advantageously has openings, in particular a perforated grid. Thus it can be made possible in a technically simple and effective way, a sufficient air supply through the cover to the control valve and thus the exhaust pipe.

Damit ein solcher Zugriff allerdings nur dazu berechtigten Personen möglich ist, weist der Zugregler ZR ein Schloss S auf, mit dem der Deckel verschlossen werden kann. Alternativ ist es auch möglich, die Abdeckung AB so an dem Gehäuserahmen GR zu befestigen, dass sie insgesamt demontiert werden kann: Diese Demontagemöglichkeit kann ebenfalls, beispielsweise über ein Schloss, ausschließlich dazu berechtigten Personen ermöglicht werden.The cover AB has in the present embodiment on the side to the outside of a door T in the form of a lid, which is removable, if necessary, to open the cover AB and thus easily access from the outside to the control valve RK and the Inside the tension controller ZR to allow. However, in order for such access to be possible only to authorized persons, the tension regulator ZR has a lock S with which the lid can be closed. Alternatively, it is also possible to attach the cover AB to the housing frame GR so that it can be dismantled as a whole: This disassembly possibility can also be made possible, for example via a lock, exclusively for authorized persons.
Um der Abgasleitung bei Bedarf genügend Luft bei geöffneter Regelklappe RK zuführen zu können, soll die Ausgestaltung des Zugreglers ZR ermöglichen, dass Luft von außen in ihn gelangen kann.In order to be able to supply sufficient air to the exhaust pipe when the control flap RK is open, the configuration of the draft regulator ZR should allow air to enter it from the outside.
Im Ausführungsbeispiel gemäß der
Besteht eine solche Beschränkung nicht, dann ist es einfachheitshalber auch möglich, die gesamte oder auch nur einen Teil der Abdeckung AB mit kleinen Öffnungen zu versehen, durch die die benötigte Luft von außen in das Innere des Zugreglers kommen kann. Beispielsweise kann die Tür bzw. der Deckel T als eine Art Lochgitter ausgestaltet sein.If such a restriction does not exist, then for the sake of simplicity it is also possible to provide the entire or even only part of the cover AB with small openings through which the required air can come from the outside into the interior of the draft regulator. For example, the door or the cover T can be designed as a type of perforated grid.
Gemäß einer nicht gezeigten Variante des Zugreglers nach der Erfindung könnte die Abdeckung sowohl einen perforierten Deckel T als auch eine Zuluftleitung ZL aufweisen, um Zuluft aus dem Installationsraum des Zugreglers und aus einem weiteren Raum zuzuführen.According to a variant of the tension regulator according to the invention, not shown, the cover could have both a perforated lid T and a Supply air line ZL have to supply supply air from the installation space of the Zugreglers and from another room.
