Abstract

A draught control system (ZR) for a heating system in a building is fitted into the bottom of a flue, e.g. adjacent to a central heating boiler, and has a control valve operating on pressure difference to maintain a preset draught up the chimney, e.g. to open and add fresh air when the flue pressure drops w.r.t. the outside. The draught control is fitted inside a tamper proof housing to prevent unauthorised adjustments. The control flaps in the draught control unit are loaded to set the pressure difference required to open the valve, e.g. with an adjustable ballast weight accessed by opening the housing. The system can be applied to single heating units as well as to flues with separate inputs from heating units on each floor.

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.The present invention relates to a tension regulator with an openable Control flap as an effective closure element depending on the pressure difference Secondary air inlet opening of an exhaust pipe, so that depending on the Area of the secondary air inlet opening there is a difference between the Pressure in the exterior and the pressure in the interior of the exhaust pipe Opening width of the secondary air inlet opening is changeable, the tension regulator has an exterior side, which is in the installed state of the train controller faces the outside of the exhaust pipe.

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 configurations and widely used in building heating systems Commitment. They are also used as draft limiters and as secondary air devices designated.

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.Draft regulators are used to train in a fireplace or chimney Burning operation of a connected fireplace essentially to keep constant or for constant pressure adjustment in the exhaust system with changing operating conditions of the fireplace or with fluctuating weather conditions, such as outside temperature, wind, etc. to care. The pressure adjustment made by the tension regulator is carried out by Mixing of 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 tension controller has a cup-shaped housing, which with its open end connected to a relevant exhaust pipe is, so that the interior of the pot-shaped housing to the interior of the Exhaust line is open, the connection point between the train controller housing and exhaust pipe is tight to the outside. On the outside The secondary air inlet opening is located on the front of the draft controller housing as well as the swinging or swiveling around a horizontal Axle-mounted control flap, which in its closed position is the secondary air inlet opening closes with overlap. In this closed position Control flap then no secondary air flows from the outside through the secondary air inlet opening through into the interior of the exhaust pipe or in the interior of the train controller housing connected to it.

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.Does the pressure in the interior decrease compared to the pressure in the exterior or on the outside of the train controller housing, so the control flap is after Providing the pressure difference from its closed position to an open position pass. Depending on the opening position of the control flap, the Secondary air inlet opening more or less wide open, so that one Flow a greater or lesser amount of secondary air into the exhaust pipe can. If the pressure in the exhaust pipe rises relative to the outside pressure at the Control flap on again, so the control flap can about its pivot axis tilt back 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 train controllers are in a separate room of a building centrally connected to the exhaust pipe. Such a room is special the boiler room of the building, where the fireplace of the (Central) heating is installed. Access to this room is common only certain people allowed the appropriate expertise possess the function and setting of the train controller.

Die Regelklappe RK ist dazu an dem Schwenklager SL des Gehäuserahmens GR um eine Schwenkachse X schwenkbar gelagert. In der Fig. 2 ist die Regelklappe RK in ihrer Schließstellung dargestellt. Die Stellung der Regelklappe RK ist von der Differenz zwischen dem Druck an der Innenraumseite, d. h. an derjenigen Seite der Nebenlufteinlassöffnung NL, die zur Abgasleitung hin weist, und dem Druck an der Außenraumseite, d. h. an derjenigen Seite der Nebenlufteinlassöffnung NL, die von der Abgasleitung weg weist, abhängig. Entsteht z. B. auf Grund eines starken Zuges in der Abgasleitung ein Unterdruck an der Innenraumseite, so neigt die Regelklappe RK dazu, die Nebenlufteinlassöffnung NL weiter zu öffnen. Bei Druckanstieg in der Abgasleitung relativ zum Druck an der Außenraumseite der Nebenlufteinlassöffnung NL neigt die Regelklappe RK dazu, in ihre Schließstellung überzugehen.There is a vertical secondary air inlet opening in the housing frame GR NL provided by the control valve RK as pressure difference dependent effective closure element can be closed or opened can. The control flap RK is on the swivel bearing SL of the housing frame GR pivotally mounted about a pivot axis X. In the Fig. 2, the control valve RK is shown in its closed position. The position the control valve RK is the difference between the pressure at the Interior side, d. H. on that side of the secondary air inlet opening NL, pointing to the exhaust pipe and the pressure on the outside, d. H. on the side of the secondary air inlet opening NL that is from the exhaust pipe points away, dependent. Arises z. B. due to a strong Train in the exhaust pipe a negative pressure on the interior side, so tends the control flap RK to open the secondary air inlet opening NL further. When the pressure in the exhaust pipe rises relative to the pressure on the outside the auxiliary air inlet opening NL tends the control flap RK into its To pass the closed position.

Der Zugregler ZR ist normalerweise auf den Mindest-Zugbedarf der an die Abgasleitung angeschlossenen Feuerstätten einzustellen. Dazu weist der Zugregler ZR ein Einstellelement zum Einstellen des Schwenkverhaltens der Regelklappe RK auf. Ein solches Einstellelement ist ein in Fig. 2 dargestellter Gegengewichtshebel GH. Das Einstellen des Schwenkverhaltens geschieht beispielsweise durch Verschrauben von Einstellgewichten EG des Gegengewichtshebels GH.The train controller ZR is usually based on the minimum train requirement Adjust the flue pipe of connected fireplaces. The Tension controller ZR a setting element for setting the swiveling behavior of the RK control flap open. Such an adjusting element is shown in FIG. 2 Counterweight lever GH. The swivel behavior is set for example by screwing adjustment weights EG des Counterweight lever GH.

An der der Abgasleitung abgewandten Seite des Gehäuserahmens GR, d. h. an der Seite des Gehäuserahmens GR, die in eingebautem Zustand dem Außenraum der Abgasleitung zugewandt ist, ist die Abdeckung AB zum Abdecken der Regelklappe RK an dem Gehäuserahmen GR befestigt. Die Abdeckung AB hat hier eine solche Größe und Form, dass die gesamte Regelklappe RK mitsamt dem Gegengewichtshebel GH abgedeckt wird. Das Material, aus dem die Abdeckung AB hergestellt ist, ist formstabil, z. B. Edelstahl. Die Abdeckung AB hat hier eine kastenförmige bzw. topfförmige Ausgestaltung, wobei der Topf so groß bemessen ist, dass die Regelklappe RK zum Regeln der Druckdifferenz und zum Öffnen der Nebenlufteinlassöffnung NL genügend weit in den Topf hinein schwenkbar ist. Die Topfform der Abdeckung AB gewährleistet eine gute Bewegungsfreiheit der Regelklappe RK. Ein solcher Kasten bzw. Topf ist einfach und kostengünstig herstellbar.On the side of the housing frame GR facing away from the exhaust pipe, d. H. on the side of the GR housing frame, which is in installed condition facing the outside of the exhaust pipe is the cover AB attached to the housing frame GR to cover the control flap RK. The cover AB here is of such a size and shape that the entire Control flap RK together with the counterweight lever GH is covered. The Material from which the cover AB is made is dimensionally stable, e.g. B. Stainless steel. The cover AB has a box-shaped or pot-shaped one Design, the pot is sized so that the control valve RK for regulating the pressure difference and for opening the secondary air inlet opening NL can be pivoted far enough into the pot. The pot shape the cover AB ensures good freedom of movement of the control flap RK. Such a box or pot is simple and inexpensive produced.

Die Abdeckung AB hat im vorliegenden Ausführungsbeispiel an der Seite zum Außenraum hin eine Tür T in Gestalt eines Deckels, welcher bedarfsweise demontierbar ist, um die Abdeckung AB zu öffnen und somit auf einfache Weise einen Zugriff von außen auf die Regelklappe RK und das Innere des Zugreglers ZR zu ermöglichen. 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 a door T in the form of a cover, which if necessary is removable to open the cover AB and thus easy Way an outside access to the control valve RK and that To enable the interior of the train controller ZR. With that, however, such access the train controller ZR only shows authorized persons a lock S with which the lid can be closed. alternative it is also possible to cover AB on the housing frame GR fasten so that it can be dismantled overall. This disassembly option can also, for example via a lock, exclusively authorized persons to do so.

Um der Abgasleitung bei ßedarf genügend Luft bei geöffneter Regelklappe RK zuführen zu können, soll die Ausgestaltung des Zugreglers ZR ermöglichen, dass Luft von außen in ihn gelangen kann.There is enough air around the exhaust pipe when the control flap is open To be able to supply RK, the design of the train controller ZR should enable that outside air can get into it.

Im Ausführungsbeispiel gemäß der Fig. 2 und der Fig. 3 verschließt die Abdeckung AB den Zugregler ZR zu dem ihn umgebenden Raum hin annähernd luftdicht. Es ist daher eine Zuluftleitung ZL vorgesehen, über die Luft von einem Außenraum in das Innere der Abdeckung AB und damit in den Zugregler ZR geführt werden kann. Der Außenraum muss dabei nicht notwendigerweise derjenige Raum sein, in dem der Zugregler ZR installiert ist. Die Zuluftleitung ZL kann vorteilhafterweise so konstruiert sein, dass sie in einen weiteren Raum oder ins Freie hinausführt. Mittels einer solchen Zuluftleitung ZL kann der Einsatz des erfindungsgemäßen Zugreglers ZR weiter an bestimmte vorgegebene Verhältnisse angepasst werden. Dies ist insbesondere dann besonders vorteilhaft, wenn aus dem Raum, in dem der Zugregler aufgestellt ist, keine Luft abgezogen werden soll.In the exemplary embodiment according to FIGS. 2 and 3, the Cover AB approximates the tension controller ZR to the room surrounding it airtight. A supply air line ZL is therefore provided, via the air from an outside space into the inside of the cover AB and thus into the Tension controller ZR can be guided. The outside space does not have to must necessarily be the room in which the train controller ZR is installed is. The supply air line ZL can advantageously be constructed in such a way that leads them into another room or outside. By means of one Supply air line ZL can use the train controller ZR according to the invention be further adapted to certain predetermined conditions. This is especially advantageous if from the room in which the Tension regulator is set up, no air should be extracted.

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. Diese Ausführung ist beispielhaft in Fig. 4 dargestellt. Die Fig. 4 zeigt eine Draufsicht auf die Außenraumseite eines zweiten Ausführungsbeispiels des Zugreglers ZR. Zu sehen ist die Tür T der Abdeckung AB. Die Tür T hat hier eine Vielzahl von runden Öffnungen L, durch die Luft von dem Raum, in dem der Zugregler ZR installiert ist, in dessen Inneres und über die Nebenlufteinlassöffnung NL in die Abgasleitung gelangen kann. Die Öffnungen L sind vorteilhafterweise so gestaltet, dass eine ausreichende Luftzufuhr gewährleistet und ein Hineingreifen von außen durch die Öffnungen L in das Innere des Zugreglers ZR nicht möglich ist. Abgesehen davon, dass bei dem zweiten Ausführungsbeispiel die Zuluftleitung ZL fehlt und der Deckel T perforiert ist, entspricht das zweite Ausführungsbeispiel im Übrigen dem ersten Ausführungsbeispiel gemäß Fig. 2 und 3. Insbesondere sollten die beiden Ausführungsbeispiele zueinander kompatibel sein, so dass der perforierte Deckel T in Fig. 4 gegen einen dicht abschließenden Deckel T in Fig. 3 auswechselbar ist und ein Anschluss für eine Zuluftleitung ZL auch bei der Ausführungsform nach Fig. 4 vorbereitet ist.If there is no such limitation, it is for the sake of simplicity also possible to use all or only part of the cover AB small openings through which the required air from the outside in the inside of the train controller can come. For example, the door or the cover T can be designed as a type of perforated grid. This version is shown by way of example in FIG. 4. 4 shows a top view of the Exterior side of a second embodiment of the train controller ZR. To see the door T of the cover AB. The door T has a variety of round openings L, through the air from the room in which the draft regulator ZR is installed, inside and via the secondary air inlet opening NL can get into the exhaust pipe. The openings L are advantageous designed so that an adequate air supply is guaranteed and a Reach in from outside through openings L into the interior of the train controller ZR is not possible. Except that in the second embodiment the supply air duct ZL is missing and the cover T is perforated, The second exemplary embodiment otherwise corresponds to the first exemplary embodiment 2 and 3. In particular, the two Embodiments to be compatible with each other, so that the perforated Lid T in FIG. 4 against a tightly fitting lid T in FIG. 3 is interchangeable and a connection for a supply air line ZL also at the 4 is prepared.

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 train controller according to the invention, not shown the cover could be both a perforated lid T and a Supply air line ZL to supply air from the installation room of the train controller and feed from another room.

Im Anwendungsbeispiel nach Fig. 1 ist der erfindungsgemäße Zugregler ZR im Keller KE des Gebäudes G an den Kamin KA angeschlossen. Es ist aber auch möglich, den Zugregler ZR in einem der Wohnräume S1 oder S2, z. B. in der Abgasleitung der jeweiligen Feuerstätte F1 bzw. F2, anzubringen. In diesem Fall hätten somit zumindest die Bewohner des Wohnraumes S1 oder S2 Zugriff auf den Zugregler ZR. Durch die erfindungsgemäße Abdeckung AB wird dies, wie oben beschrieben, verhindert. Durch Verwendung einer Zuluftleitung ZL, die z. B. nach draußen ins Freie geführt ist, wird verhindert, dass dem Wohnraum S1 oder S2, in dem der Zugregler ZR aufgestellt ist, Luft entzogen wird.In the application example according to FIG. 1, the tension controller according to the invention is ZR in the basement KE of building G connected to the chimney KA. But it is also possible, the train controller ZR in one of the living rooms S1 or S2, z. B. in the flue gas pipe of the respective fireplace F1 or F2. In in this case, at least the residents of living area S1 would have or S2 Access to the train controller ZR. Through the cover according to the invention AB, this is prevented as described above. By using a supply air line ZL, the z. B. is led outside, prevents the living area S1 or S2, in which the train controller ZR is set up, air is extracted.
