Erfahrungsmäfsig können beim Füllen der Wasserleitungsrohre gröfsere Quantitäten Luft unter Druck eingeschlossen werden, die beim Oeffnen der Gebrauchshähne durch den Wassermesser strömen und hier als Wasser gemessen und bezahlt werden. Die Gefahr ist um so. gröfser, als Luft vermöge ihres geringen specifischen Gewichtes in unverhältnifsmäfsig gröfserer Menge durch eine enge Oeffnung durchgeht als Wasser.Experience has shown that larger quantities of air can be used when filling the water pipes are enclosed under pressure when the utility taps are opened by the water knife stream and are measured and paid for here as water. The danger is so. larger than air, due to its low specific gravity, disproportionately larger Much passes through a narrow opening as water.
Diesem Uebelstande wird durch das in Zeichnung vorgelegte Wassermesser-Schutzventil abgeholfen, welches Wasser ungehindert, Luft aber gar nicht durchströmen läfst. Das bei A einströmende Wasser hebt den Schwimmer B, wodurch das entlastete Doppelventil C gehoben und der Austritt nach D ermöglicht wird. Tritt an Stelle des Wassers Luft, so kann der Schwimmer B nicht schwimmen und das Ventil C bleibt ungehoben, wodurch der Ausgang D geschlossen bleibt.This inconvenience is remedied by the water knife protection valve shown in the drawing, which allows water to flow through unhindered, but not air at all. The water flowing in at A lifts the float B, which lifts the relieved double valve C and enables the outlet to D. If air takes the place of the water, the float B cannot swim and the valve C remains unlifted, whereby the outlet D remains closed.
Aufserdem ist bei E ein Sieb angeordnet, um fremde Körper von dem Ventil und vom Wassermesser abzuhalten.In addition, a sieve is arranged at E to keep foreign bodies from the valve and the water meter.
