Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung besteht in einer fortschrittlichen Ausbildung der bekannten, im ganzen herausnehmbaren, durch einen Schwimmer bewegten Rückstauverschlüsse in der Weise, daß der Rückstauverschluß nicht nur im ganzen herausgenommen, sondern auch in seinen wesentlichen Teilen genau bearbeitet werden kann. Außerdem sind die Gelenke und Verbindungsglieder zwischen Ventilklappe und Schwimmer gegen Verunreinigungen geschützt.The invention consists in an advanced embodiment of the known, on the whole removable backflow stops moved by a float in such a way that the backflow stop not only removed in its entirety, but also in its essentials Parts can be edited accurately. Also are the joints and connecting links Protected against contamination between the valve flap and the float.
In der Zeichnung ist der Erfindungsgegenstand in Fig. ι in einem Längsschnitt und in Fig. 2 in einem Querschnitt dargestellt.In the drawing, the subject of the invention is in Fig. Ι in a longitudinal section and in Fig. 2 shown in a cross section.
Der herausnehmbare Ventilsitz ν wird mit der Schraube s und Dichtung d gegen die . Wand w des Kastengehäuses gedrückt, wobei der daumenförmige Fortsatz α eine Stütze bildet, die ein gleichmäßiges Anpressen des Ventilsitzes an die K asten wand gewährleistet. An den Ventilsitz angegossen ist ein Gehäuse g, das zur Lagerung des Drehbolzens b für die Abschlußklappe e und des Drehbolzens c für den Hebel f des Schwimmers k dient; außerdem enthält es die die Bewegung der Klappe steuernden Zahnbogen h und i, die dadurch vor Verunreinigungen geschützt sind.The removable valve seat ν is with the screw s and seal d against the. Wall w of the box housing pressed, the thumb-shaped extension α forming a support that ensures uniform pressing of the valve seat against the box wall. A housing g is cast on the valve seat and serves to support the pivot pin b for the closing flap e and the pivot pin c for the lever f of the float k; it also contains the dental arches h and i which control the movement of the flap and which are thereby protected from contamination.
Die Wirkungsweise der Vorrichtung ist folgende :The device works as follows:
Tritt ein Rückstau des Wassers in dem Kanalrohr ein, so hebt sich der Schwimmer k und drückt mit Hilfe der Zahnbogen h, i die Klappe e auf den Sitz ν, so daß das Wasser durch das Zuflußrohr nicht weiter vordringen kann.If the water backs up in the sewer pipe, the float k rises and, with the help of the tooth arches h, i, presses the flap e onto the seat ν, so that the water cannot penetrate any further through the inlet pipe.
