Description
Rohrbelüfter, insbesondere solche für sanitäre Kalt- und verhindern durch Einführung von Luft in die Rohrleitung den Rückfluß von Gebrauchtwasser in die Frischwasserleitung für den Fall, daß ein Unterdruck in der Frischwasserleitung entstel:+ Zu diesem Zweck besitzen die Rohrbelüfter Absperrvorrichtungen in Form von Kegel- oder Kugelventilen, die sich normalerweise in geschlossenem Zustand befinden, durch ihr eigenes Gewicht und den Fließdruck des Wasserstromes abdichten und bei eintretendem Unterdruck vom äußeren atmosphärischen Luftdruck geöffnet werden. Die Ventile arbeiten nur zufriedenstellend, wenn ihr Einbau genau senkrecht erfolgt. Dies trifft besonders für Durchlauf-Rohrbelüfter zu.Pipe aerators, especially those for sanitary cold and prevent by introducing air into the pipeline, the reflux of used water in the fresh water line in the event that there is a negative pressure in the fresh water line entstel: + For this purpose, the pipe aerators have shut-off devices in the form of cone or ball valves, which are normally in the closed state, seal by their own weight and the flow pressure of the water flow and at incoming negative pressure can be opened by the external atmospheric air pressure. the Valves only work satisfactorily if they are installed exactly vertically. This is especially true for continuous pipe aerators.
Im folgenden ist ein Durchlauf-Rohrbelüfter beschrieben, .der in jeder Einbaustellung einwandfrei arbeitet, so daß er beispielsweise ohne Schwierigkeit an dem schrägen Auslaufrohrbogen einer Badeofenbatterie zwischen Bogen und Schlauch wie auch -in waagerechter Stellung zwischen seitlichen Auslaufstutzen einer Brausebatterieauflegegabel und Brauseschlauch eingebaut werden kann. -Fig. i zeigt einen Längsschnitt durch den Belüfter; Fig.2 zeigt einen Querschnitt durch den Belüfterentlang der Linie A-A; Fig. 3 zeigt eine Draufsicht auf die Membrandichtung.A continuous pipe aerator is described below Installed position works properly, so that he can, for example, without difficulty on the inclined outlet pipe bend of a bath heater battery between the bend and the hose as well as -in a horizontal position between the lateral outlet nozzle of a shower mixer attachment fork and shower hose can be installed. -Fig. i shows a longitudinal section through the aerator; Figure 2 shows a cross section through the aerator along the line A-A; Fig. 3 shows a plan view of the membrane seal.
Der Belüfter besteht aus dem Gehäuseteil i, der Membrandichtung 2 und der Kappe 3. Um ein eventuelles Aufkleben der Gummimembran 2 auf dem Ventilsitz 4 zu vermeiden, liegt die Membran 2 in Normalstellung ein bestimmtes Maß über dem Ventilsitz 4. Erst während des Betriebes liegt die Membran 2 infolge des Fließdruckes auf dem Ventilsitz 4 auf, oder mittels des Kanals 5 mit der Außenluft inVerbindung steht. Somit ist der durchströmenden Flüssigkeit der Austritt durch den Ventilsitz 4 hindurch gesperrt. Die durchströmende Flüssigkeit nimmt ihren Weg .durch die Öffnungen 6 .der Membran 2. Tritt durch irgendwelche Umstände ein Unterdruck in der Leitung ein, wird die Membran z durch den atmosphärischen Druck von dem Ventilsitz 4 abgehoben, so daß durch den Kanal 5 Luft in,die Leitung einströmen kann, wodurch der Rückfluß von Abwasser in die Frischwasserleitung verhindert wird.The aerator consists of the housing part i, the diaphragm seal 2 and the cap 3. In order to avoid the rubber diaphragm 2 sticking to the valve seat 4, the diaphragm 2 lies a certain amount above the valve seat 4 in the normal position Membrane 2 due to the flow pressure on the valve seat 4, or by means of the channel 5 is in communication with the outside air. The exit through the valve seat 4 is thus blocked for the liquid flowing through. The liquid flowing through takes its way through the openings 6 of the membrane 2. If, due to any circumstances, a negative pressure occurs in the line, the membrane z is lifted off the valve seat 4 by the atmospheric pressure, so that through the channel 5 air enters, the line can flow in, whereby the backflow of waste water into the fresh water line is prevented.
