Description

Einrichtung zur Bestimmung der Verlustmengen infolge Undichtigkeiten in Wasserleitungen, die von Hochbehältern führen. Die Erfinduflg betrifft eine neue Einrichtung zur Messung der--- Verlustmengen in Wass,erleitungen, die von Hochbehältern, Staubecken und ähnlichen Wasservorratsbebältern führen.Device for determining the quantities lost as a result of leaks in water pipes that lead from elevated tanks. The invention relates to a new one Device for measuring the --- quantities lost in water pipes from elevated tanks, Lead reservoirs and similar water storage tanks.

Im allgemeinen sind, soweit überhaupt Wasserleitungen- auf - Dichtigkeit geprüft worden sind, für diese Prüfung lediglich die in jeder Falleitung angebrachten Wassermesser oder auch ein am tiefsten Punkt der Leitung angebrachtes Manometer benutzt worden. Für solche Wasserwerke, die während einer Zeitdauer von mindestens zwölf Stunden kein. Wasser abzugeben brauchen und wo ferner die Ge'vvähr dafür besteht, daß während dieser langen Zeit keiner Zapfstelle unbemerkt Wasser entnommen wird, reicht . die eine oder andere Art der Prüfung der Leitungen wohl aus. Da aber für solche lange Zeit die Wasserentnahme in - den seltensten Fällen ganz unterbunden- werden kann, scheiden die beiden angegebenen Arten der Untersuchung der Leitungen auf Dichtigkeit wohl für die meisten Anlagen aus. Der Grund für die Notwendigkeit der zwölfstündigen Ausdehnung des Versuches liegt darin, daß der unmittelbar in die Hauptleitung eingebaute Wassermesser und das Manometer kleinere Wasserverluste nicht anzeigen. Die Leistungsfähigkeit des Messers ist. dem großen Durchmesser der Falleitung angepaßt. Am Manometer werden kleinere Wasserverluste nicht ablesbar sein, weil die Falleitungen mit dem großen Wasservorrat im Hochbehälter in Verbindung stehen.In general, water pipes - if at all - are tight have been checked, for this check only those attached in each downpipe Water meter or a pressure gauge attached to the lowest point of the line been used. For those waterworks that operate for a period of at least twelve hours no. Need to give up water and where there is also a need to that during this long time no tapping point is taken unnoticed, enough . one or the other type of test of the lines probably off. But there for such a long time the water withdrawal in - in the rarest cases completely prevented - can be, separate the two types of investigation of the lines indicated on tightness for most systems. The reason for the need of the twelve-hour extension of the experiment lies in the fact that the immediately in the main line built-in water meter and the pressure gauge minor water losses not show. The efficiency of the knife is. the large diameter of the Fall line adapted. Smaller water losses cannot be read on the pressure gauge because the downpipes are connected to the large water supply in the elevated tank stand.

Die Erfindung bezweckt, diesen Übelstand zu beseitigen, und erreicht dies dadurch, daß mit dem Fallrohr ein Wässerstandsmesser verbunden ist, der nach Abschluß des Fallrohres' vom Hochbehälter oder vom Staubecken das Absinken des Wassers bei einer dem Behälterinhalt entsprechenden Anfangsdruckhöhe - infolge Undichtigkeit des zwecks Prüfung abgesperten Leitungsnetzes unmittelbar anzeigt.The invention aims to remedy this drawback and achieves it this in that a water level meter is connected to the downpipe, which after Completion of the downpipe 'from the elevated tank or from the reservoir, the sinking of the water at an initial pressure level corresponding to the container contents - as a result of a leak of the pipeline network that has been cordoned off for testing purposes.

In: der Zeichnung ist die neue Meßeinrichtung in einem Ausführungsbeispiel gezeigt. Gemäß der dargestellten Ausführungsform kommuniziert mit dem Hochbehälter ein Wasserstandsglas A und B, das zweckmäßig mit einer Skala versehen ist. Bei Prüfung des Leitungsnetzes werden in diesem sämtliche Entnahmesfellen gesperrt. Das Abschlußorgan IV wird geöffnet und das Fallrohr durch Abschluß des Absperrorgans I vom Hochbehälter abgeschaltet. Schließlich wird auch noch die Verbindung zwischen den Meßrohren A und B und dem Hochbehälter durch Abschluß, der Organe V abgeschaltet. Sind nun. in der völlig abgesperrten, zu prüfenden Leitung Undichtigk citen vorhanden, so sinkt der Wasserspiegel in dem Fallrohr und damit auch in den Meßröhren verhältnismäßig schnell. Aus dem Durchmesser der Meßgläser A und B und der Geschwindigkeit, mit welcher das Wasser in diesen absinkt, läßt sich die Größe des Leitungsverlustes ohne Schwierigkeiten sofort bestimmen,. und das Leitungsnetz kann gegebenenfalls wieder für den Gebrauch freigegeben werden.In: the drawing shows the new measuring device in an exemplary embodiment. According to the embodiment shown, a water level glass A and B, which is expediently provided with a scale, communicates with the elevated tank. When the pipeline network is checked, all extraction skins are blocked. The closing element IV is opened and the downpipe is switched off by closing the shut-off element I from the elevated tank. Finally, the connection between the measuring tubes A and B and the elevated tank is shut off by closing the organs V. Are now. If there are leaks in the completely shut off line to be tested, the water level in the downpipe and thus also in the measuring tubes drops relatively quickly. From the diameter of the measuring glasses A and B and the speed with which the water sinks in them, the size of the line loss can be determined immediately without difficulty. and the line network can be released for use again if necessary.
