Description

Selbsttätiges Luftventil mit nachgiebiger Dichtungsfläche zur Verhinderung des Absaugens von Geruchverschlüssen. Die Erfindung ist ein selbsträtiges Luftventil mit nachgiebiger Dichtungsfläche zur Verhinderung des Absaugens von Geiuchverschlüssen. Sie besteht in einer in ihrer Mitte ausgeschnittenen, an den Lüftungsrohrstutzen durch Ring befestigten nachgiebigen Scheibe, die über den unteren Lufteintrittsöffnungen mit ihrem Außenrand auf den Innenrand einer nachgiebigen Ringscheibe abdichtet.Automatic air valve with resilient sealing surface to prevent the suction of odor traps. The invention is an automatic air valve with flexible sealing surface to prevent odor seals from being sucked off. It consists of a cut out in the middle on the ventilation pipe socket resilient disc fastened by a ring that covers the lower air inlets seals with its outer edge on the inner edge of a flexible washer.

Den bekannten Luftventilen zui Verhinderung des Absaugens von Geruchverschlüssen gegenüber bietet der Erfindungsgegenstand bedeutende Vorteile dadurch, daß hier die Verwendung jeglicher Flüssigkeit sowie starre, metallische Dichtungsflächen mit Federn u. dgl. vermieden sind.The well-known air valves to prevent odor traps from being sucked off compared to the subject invention offers significant advantages in that here the use of any liquid as well as rigid, metallic sealing surfaces with springs and the like are avoided.

Die Erfindung ist in der Zeichnung dargestellt.The invention is shown in the drawing.

Abb. i ist eine Seitenansicht mit teilweisem Schnitt des geschlossenen Ventils.Fig. I is a side view in partial section of the closed one Valve.

Abb. 2 ist ein senkrechter Schnitt des eingebauten geöffneten Ventils.Fig. 2 is a vertical section of the installed open valve.

Abb. 3 ist eine Ansicht von unten.Fig. 3 is a bottom view.

Durch die Verwendung von zwei übereinander gelegten nachgiebigen Ringscheiben b und c, die gleichzeitig durch die Ringe e und f abdichtend an den Lüftungsrohrstutzen a befestigt sind, ist ein Festrosten des Ventilsitzes, selbst bei längerer, dauernder Ruhelage (Abb. i), ausgeschlossen, weil die Dichtungsflächen nicht mit Metall in Berührung kommen. Infolge der leicht federnden Spannung der in der Mitte ausgeschnittenen nachgiebigen Scheibe b ist es gleichgültig, in welcher Lage das Ventil angebracht wird, d. h. es braucht nicht wie bei Ventilen mit Flüssigkeiten, Kugeln u. dgl. auf genauen senkrechten Sitz geachtet Urerden.By using two flexible ring disks placed one on top of the other b and c, which are sealed at the same time by the rings e and f on the ventilation pipe socket a, rusting of the valve seat is more permanent, even for a longer period of time Rest position (Fig. I), excluded because the sealing surfaces are not in contact with metal Come into contact. As a result of the slightly springy tension of the cut out in the middle flexible disk b, it does not matter in which position the valve is attached will, d. H. it does not need, as is the case with valves with liquids, balls and the like. Urerden paid attention to an exact vertical seat.

Die unter der Scheibe b ringförmig in dem tellerartig verbreiterten Rohrstutzen a angebrachten Lufteintrittsöffnungen a1 ergeben einen verhältnismäßig großen Querschnitt bzw. eine große Angriffsfläche und- bewirken somit ein äußerst empfindliches und leichtes Arbeiten des Ventils.The ring-shaped under the disc b in the widened plate-like Pipe socket a attached air inlet openings a1 result in a relatively large cross-section or a large attack surface and thus cause an extremely sensitive and easy working of the valve.

Durch die mit dem Schraubring e befestigte kappe d ist das Ventil vollkommen abgeschlossen und vor Schmutz und Staubablagerungen geschützt. Die in Abb. 2 eingezeichneten Pfeile ,eben die Luftströmung an.The valve is opened through the cap d fastened with the screw ring e completely closed and protected from dirt and dust deposits. In the Fig. 2 drawn arrows, just the air flow.
