Abstract

The system to prevent a backflow of waste water and sewage at a building, in flood conditions, has a sewage outflow housing with a float (4). The float (4) is at a guide (5) which, under a counter pressure, blocks sewage outflow from the building and prevents an inflow from the sewage drains as long as water runs against the outflow direction in the backflow barrier. The float head is a hemisphere with a larger diameter than the outflow pipe (3) to give a complete seal on high water, and is constantly flushed to ensure a complete sealing action.

Description

Die Erfindung bezieht sich auf ein Abwassergehäuse mit Schwimmer (4).The invention relates to a waste water housing with a float ( 4 ).

Fig. 1: Der Schwimmer (4) kann auf einer Führung (5) bei Gegendruck nach oben steigen und den Wasserabfluss vom Haus sperren und Zufluss vom Kanalsystem verhindern, sobald Wasser entgegen der Abflussrich­ tung in den Rückflussverhinderer einfließt. Der Schwimmerkopf ist Halb­ kugelartig und hat einen größeren Durchmesser als das darüber münden­ te Abflussrohr. So dichtet er bei Hochwasser vollkommen ab. Er ist genau unter dem Abflussrohr platziert und wird so von dem Wechsel zwischen stark und weniger verschutztem Abwassers ständig sauber gespült, damit er im Ernstfall richtig dichtet. Fig. 2. Fig. 1: The float ( 4 ) can rise on a guide ( 5 ) with back pressure upwards and block the water drainage from the house and prevent inflow from the sewer system as soon as water flows into the backflow preventer in the opposite direction. The float head is hemispherical and has a larger diameter than the drain pipe opening above it. This is how it seals completely during floods. It is placed exactly under the drain pipe and is constantly rinsed clean by the change between heavily and less polluted waste water so that it seals properly in an emergency. Fig. 2.

Fig. 4 zeigt die Abflusseite des Rückflussverhinderers. Fig. 4 shows the drain side of the backflow preventer.
