wenn in Rohrleitungen ein brennbares Medium gefördert wird oder wenn die Gefahr besteht, dass aufgrund eines fcareits bestehenden Brandes brennende oder brennbare Materialien in ein Rohrleitungsnetz gelanger können. Bei Klimaanlagen kann eine besonders gefährliche Situation dann entstehen, wenn sich fetthaltige Ablagerungen in Entlüftungskanälen von Küchen entzünden. Werden solche Entlüftungskanäle nicht unmittelbar nach der Entzündung der Ablagerungen verschlossen, ist eine Ausbreitung des Brandes über das Netz der Entlüftungskanäle unausv;eichlich.if a flammable medium is conveyed in pipelines or if there is a risk that due to a fcareit existing fire, burning or combustible materials can get into a pipeline network. With air conditioning systems, a particularly dangerous situation can arise when there are fatty deposits ignite in ventilation ducts of kitchens. Will such Ventilation ducts not closed immediately after the inflammation of the debris is a spread of the Fire cannot be balanced through the network of ventilation ducts.

Weiter besteht im Brandfall die Gefahr, dass sich üer Druck im Leitungsnetz erhöht. Ein zuverlässiges Schliessen von Brandschutzarmaturen kann unter Umständen nur dann gewährleistet werden, wenn die das Absperrorgan betätigende Vorrichtung mit entsprechendem konstruktivem Aufwand für solche Fälle dimensioniert ist.In the event of a fire, there is also the risk that the pressure in the pipeline network will increase. A reliable one The closing of fire protection fittings can only be guaranteed under certain circumstances if the shut-off device actuating device is dimensioned with a corresponding structural effort for such cases.

Bekannte Brandschutzarmaturen weisen den Nachteil auf, dass das Absperrorgan in Offenstellung vom Medium umströmt wird, unerwünschte Turbulenzen und/oder eine Verengung des Strömungsquerschnitts sind die Folge, wenn nicht das Armaturengehäuse entsprechend erweitert wird.Known fire protection fittings have the disadvantage that the shut-off device in the open position from the medium is flowed around, unwanted turbulence and / or a narrowing of the flow cross-section are the result if the valve body is not expanded accordingly.

An solchen Punkten können jedoch beschränkte Platzverhältnisse herrschen· Eine Armatur, welche ein aufgrund von Strömungsverhältnissen und Absperrorganantrieb vergrössertes Gehäuse aufweist, muss unter Umständen des Platzmangels wegen an anderen Orten vorgesehen werden. Zweck der vorliegenden Erfindung ist es nun, diese Nachteile zu überwinden. Dazu zeichnet sich die Brandschutzarmatur erfindungsgemäss dadurch aus, dass das Ab-* sperrorgan um eine entlang einer seiner Seiten verlaufende Achse im Gehäuse verschwenkbar gelagert ist, wobei das Absperrorgan in Offenstellung parallel zu einer Gehäusewand in einer in letzteren gebildeten Mische versenkt ist und in Schliessstellung rundum an die Abflussöffnung umgebende Dichtflächen anliegt*net used at certain points, e.g. in front of branches. However, at such points there can be limited Space conditions prevail · A valve which, due to flow conditions and the shut-off valve drive Has enlarged housing, may have to be provided in other places because of the lack of space. The purpose of the present invention is now to overcome these disadvantages. The fire protection fitting stands out for this according to the invention characterized in that the shut-off member around a running along one of its sides Axis is pivotably mounted in the housing, the shut-off element in the open position parallel to a housing wall is sunk in a mixture formed in the latter and surrounding the drain opening in the closed position all around Sealing surfaces rests on *

Durch die Versenkung des Absperrorgans in einer durch eine Gehäusewand gebildeten Nische wird erreicht, dass die Strömung durch die Armatur nur in unwesentlichem Mass gestört wird, im Vergleich mit bekannten Armaturen können zudem die Abmessungen des Gehäuses kleiner gehalten werden.By sinking the shut-off element in a niche formed by a housing wall, it is achieved that the flow through the valve is only disturbed to an insignificant extent in comparison with known valves the dimensions of the housing can also be kept smaller.

Soll das Absperrorgan von der Offen- in die Schliessstellung verschwenkt werden, so genügt dazu ein geringes Moment um die Verschwenkachse, da die Verschwenkbewegung in Strömungsrichtung erfolgt. Die Verschwenkung des Absperrorgans wird somit durch die Strömung unterstützt; in der Zuführungsleitung eventuell herrschender Ueberdruck presst das Absperrorgan gegen die die Abflussöffnung umgebenden Dichtflächen in Schliessstellung. Die das Absperrorgan betätigende Vorrichtung kann mit geringemIf the shut-off element is to be swiveled from the open to the closed position, one is sufficient small moment about the pivot axis, since the pivoting movement takes place in the direction of flow. The pivoting the shut-off device is thus supported by the flow; possibly more prevalent in the supply line Overpressure presses the shut-off element against the sealing surfaces surrounding the discharge opening in the closed position. the the shut-off device actuating device can with little

In einem bevorzugten Ausführungsbeispiel ist die der Verschwenkachse entlang verlaufende Seite des Absperrorgans mit einer im Querschnitt halbkreisförmig nach aussen gewölbten Oberfläche versehen. Das Absperrorgan ist in der direkt an die Abflussöffnung angrenzenden Nische derart vorgesehen, dass die im Querschnitt halbkreisförmig nach aussen gewölbte Oberfläche die entsprechende Nischenwand in jeder Stellung des Absperrorgans dichtend berührt. Dichtflächen an der Abflussöffnung müssen dann nur noch für die restlichen Seiten des Absperrorgans vorgesehen werden.can be realized with constructive effort and space-saving. In a preferred embodiment, the the pivot axis running along the side of the shut-off member with a semicircular cross-section to the outside curved surface. The shut-off device is of this type in the niche directly adjacent to the drain opening it is provided that the surface, which is curved outward in a semicircular cross section, forms the corresponding niche wall in every position of the shut-off element. Sealing surfaces on the drain opening then only have to be be provided for the remaining sides of the shut-off device.
