Abstract
Strömungskanal mit einem nach oben ausblasenden Ausblasstutzen (9) und einer den Ausblasstutzen (9) verschließenden, strömungsbetätigten, um eine horizontale Drehachse (14) verschwenkbaren Ausblasklappe (13), dadurch gekennzeichnet, daß die Längsachse des Ausblasstutzens (9) unter einem Winkel von 45° gegen die Horizontale geneigt ist und daß die Ausblasklappe (13) in der Austrittsebene des Ausblasstutzens (9) angeordnet ist und im geschlossenen Zustand unter einem Winkel von 45° gegen die Horizontale steht, daß die Ausblasklappe (13) durch die Drehachse (14) in zwei ungleich große Abschnitte (16, 17) aufgeteilt ist und daß die Drehachse (14) oberhalb des Schwerpunktes der Ausblasklappe (13) vorgesehen ist, daß in dem Strömungskanal ein kombinierter Lüftungs- und Brandgasventilator angeordnet ist und daß der Ventilator als Radialventilator ausgebildet ist und eine Nabenscheibe (6) enthält, die in der gleichen axialen Hälfte des Strömungskanales angeordnet ist wie der kürzere Abschnitt (16) der Ausblasklappe (13), wobei der kürzere Abschnitt (16) der Ausblasklappe (13) ebenso wie die Nabenscheibe (6) des Ventilatorrades (3) in dem oberen Teil des Ventilatorgehäuses (1) liegt.Flow channel with an upward blow-out spout (9) and a flow-actuated blow-out flap (13) which closes the blow-out spout (9) and can be pivoted about a horizontal axis of rotation (14), characterized in that the longitudinal axis of the blow-out spout (9) is at an angle of 45 ° is inclined to the horizontal and that the blow-out flap (13) is arranged in the exit plane of the blow-out connector (9) and in the closed state is at an angle of 45 ° to the horizontal that the blow-out flap (13) is rotated by the axis of rotation (14) is divided into two unequal sections (16, 17) and that the axis of rotation (14) is provided above the center of gravity of the blow-out flap (13), that a combined ventilation and combustion gas fan is arranged in the flow channel and that the fan is designed as a radial fan and contains a hub disc (6) which is arranged in the same axial half of the flow channel as that shorter section (16) of the blow-out flap (13), the shorter section (16) of the blow-out flap (13) as well as the hub disk (6) of the fan wheel (3) being located in the upper part of the fan housing (1).
Description
Die Erfindung betrifft einen Strömungskanal mit einem Ausblasstutzen und einer strömungsbetätigten Ausblasklappe mit den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to a flow channel with a discharge nozzle and a flow-actuated exhaust flap with the features of the preamble of claim 1.
Werden derartige Strömungskanäle, die auf dem Dach eines Gebäudes angeordnet sind, von einem heißen Gas durchströmt, so muß verhindert werden, daß diese Gase in Richtung auf das Dach ausgeblasen werden. Anderenfalls besteht die Gefahr, daß die Dachhaut entflammt wird. Es besteht eine behördliche Forderung, daß maschinelle Rauchgasabzüge in Verbindung mit Brandgasventilatoren einen Ausblaswinkel von 45 bis 90° aufweisen müssen. Andererseits ist die Schneelast zu berücksichtigen, die sich zur Winterzeit auf dem Dach und den darauf angeordneten Aggregaten ablagern kann.If such flow channels, which are arranged on the roof of a building, flows through a hot gas, it must be prevented that these gases are blown out in the direction of the roof. Otherwise, there is a risk that the roof skin is inflamed. There is a regulatory requirement that machine flue gas fumes in conjunction with combustion gas fans must have a discharge angle of 45 to 90 °. On the other hand, the snow load must be taken into account, which can be deposited on the roof and the aggregates arranged thereon in winter.

In der
Der Erfindung liegt die Aufgabe zugrunde, den gattungsgemäße Strömungskanal so zu gestalten, daß beim Austritt von heißen Gasen keine Entflammung der Umgebung, insbesondere der Dachhaut besteht und daß gleichzeitig die Anordnung schneesicher ist.The invention has for its object to make the generic flow channel so that when the escape of hot gases no ignition of the environment, in particular the roof membrane and that at the same time the arrangement is snow sure.
Diese Aufgabe wird bei einem gattungsgemäßen Strömungskanal erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand des Unteranspruchs.This object is achieved according to the invention in a generic flow channel by the characterizing features of claim 1. Advantageous embodiments of the invention are the subject of the subclaim.
Die Ausrichtung des Ausblasstutzen ergibt einen Ausblaswinkel, der im zulässigen Bereich liegt. Außerdem kann bei dieser Ausrichtung des Ausblasstutzens die Ausblasklappe im geschlossenen Zustand unter einem solchen Winkel eingebaut werden, daß im gegebenen Fall Schnee von der Oberfläche der Ausblasklappe abrutschen wird. Die Ausblasklappe braucht daher keiner speziellen Schneelastprüfung unterworfen zu werden.The orientation of the outlet nozzle results in a discharge angle which is within the permissible range. In addition, in this orientation of the Ausblastutzens the exhaust flap can be installed in the closed state at an angle such that in the given case snow from the surface of the exhaust flap will slip off. The exhaust flap therefore need not be subjected to a special snow load test.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher erläutert. Es zeigen:An embodiment of the invention is illustrated in the drawing and will be explained in more detail below. Show it:
Auf dem Dach oder an der Wand eines nicht gezeigten Gebäudes ist ein Strömungskanal angeordnet, durch den ein Gas gefördert wird, das unter Umständen heiß sein und eine Temperatur von maximal 630°C aufweisen kann. Im dargestellten Fall ist der Strömungskanal durch das rechteckige Ventilatorgehäuse
