Description

Durchfluß-Rohrbelüfter mit eingebautem Rückflußverhinderer Flow-through tube aerator with a built-in backflow preventer

Die bisher bekannten, auf dem Markt befindlichen Durchfluß-Rohr- ; belüfter, Bestandteil der DIN-Vorschrift I988, verhindern die Rücksaugung von Schmutzwasser in das Leitungsnetz bei Unterdruck in der Zuflußleitung. Da außerdem aus Sicherheitsgründen beim Anschluß von Geräten, beispielweise^ Waschmaschinen, Waschautomaten, Geschirrspülmaschinen usw. ein Rückflußverhinderer gefordert wird, der auch bei Unterdruck in der Geräteanschlußleitung wirksam wird, haben wir - hiermit kommen wir zum Gegenstand unserer Erfindung - eine entsprechende Kombinationsarmatur entwickelt, die wir als Durchfluß-Rohrbelüfter mit eingebautem Rückflußverhinderer bezeichnen.The previously known, on the market flow tube; aerators, part of DIN regulation I988, prevent the Suction of dirty water back into the pipe network when there is negative pressure in the inflow pipe. As also for security reasons when connecting devices, e.g. ^ washing machines, washing machines, Dishwashers, etc. a backflow preventer is required, which is also in the case of negative pressure in the device connection line becomes effective, we have - this brings us to the subject of our invention - developed a corresponding combination valve that we as flow tube aerators with built-in backflow preventer describe.

Die Rohrbelüftung wird dadurch bewirkt, daß sich bei Unterdruck in der Zuflußleitung der Ventilteller 11, der mit einer Dichtung ausgestattet, und mit einem Profilansatz 9 in einer Bohrung geführt ist, vom Ventalsitz abhebt und die Luft durch die im Rohrbelüfter Körper 7 befindlichen Belüftungsöffnungen eingesaugt werden kann, welche die Wassersäule unterbricht und somit die Rücksaugung von Schmutzwasser in die Versorgungsleitung verhindert. Stellt sich nach dem Unterdruck wieder normaler Druck ein, so fällt der Ventilteller Xl. auf den Ventilsitz zurück und der normale Durchfluß ist wieder hergestellt. The pipe ventilation is caused by the fact that when there is negative pressure in the supply line, the valve plate 11, which is equipped with a seal and is guided in a bore with a profile attachment 9, lifts from the valve seat and the air is sucked in through the ventilation openings in the pipe aerator body 7 which interrupts the water column and thus prevents dirty water from being sucked back into the supply line. If normal pressure is established again after the negative pressure, the valve disk Xl falls. back on the valve seat and normal flow is restored.

Entsteht in der Geräteanschlußleitung ein Überdruck, so wird die mit einer Dichtung j5 ausgestattete Ventilkappe 2 gegen den Ventilsitz im Gewindestück 1 gepreßt und verhindert somit ein Eindringen von Schmutzwasser in die Versorgungsleitung. Die Feder 5.. im Ventilkörper 6 geführt, bewirkt, daß auch im drucklosen Zustand das Ventil geschlossen ist.If there is overpressure in the device connection line, the with a seal j5 equipped valve cap 2 against the valve seat pressed in the threaded piece 1 and thus prevents the ingress of dirty water into the supply line. The spring 5 .. in the valve body 6 out, has the effect that the valve is closed even in the depressurized state.

Die Kombinationsarmatur Durchfluß-Rohrbelüfter mit eingebautem Rückflußverhinderer kann an alle handelsüblichen Auslaufventile angebracht werden, die am Auslauf mit einem R 3/4" Rohrgeviinde versehen sind.The combination valve flow-tube aerator with built-in non-return valve can be attached to all commercially available outlet valves that have a R 3/4 "pipe thread at the outlet.
