Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren sowie eine Vorrichtung zur Leckerkennung in einer Wasserinstallation.The The present invention relates to a method and a device for leak detection in a water installation.
Wie
in
Zur
Vermeidung einer Verschwendung des Trinkwassers und Beschädigungen
von Einrichtungen durch austretendes Wasser ist es erwünscht, ein Leck
in der Wasserinstallation möglichst
frühzeitig
zu erkennen. Derzeit besteht die Möglichkeit, ein Leck in der
Wasserinstallation
Es ist eine Aufgabe der vorliegenden Erfindung, ein Verfahren und eine Vorrichtung zur Leckerkennung in einer Wasserinstallation vorzusehen, die auch zur Erfassung sehr kleiner Leckagen geeignet sind.It is an object of the present invention, a method and a To provide a leak detection device in a water installation, which are also suitable for detecting very small leaks.
Diese Aufgabe wird gelöst durch ein Verfahren zur Leckerkennung in einer Wasserinstallation mit den Merkmalen des Anspruchs 1 bzw. eine Vorrichtung zur Leckerkennung in einer Wasserinstallation mit den Merkmalen des Anspruchs 8. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.These Task is solved by a leak detection method in a water installation with the features of claim 1 and a device for leak detection in a water installation with the features of claim 8. Advantageous embodiments and further developments of the invention are specified in the dependent claims.
Erfindungsgemäß wird zur Leckerkennung in einer Wasserinstallation, die über ein Zuleitungsrohr an einen Versorgungsanschluss angeschlossen ist, das Zuleitungsrohr mittels einer Ventilvorrichtung gesperrt; der Wasserdruck in dem Zuleitungsrohr stromab der Ventilvorrichtung mittels einer Druckerfassungsvorrichtung erfasst; und ein Leck in der Wasserinstallation bestimmt, wenn ein Abfall des erfassten Wasserdrucks einen vorbestimmten Wert überschreitet. Mit anderen Worten wird zur Leckerkennung in der Wasserinstallation ein Druckabfall ausgewertet.According to the invention is for Leak detection in a water installation, via a supply pipe to a Supply connection is connected, the supply pipe by means of a valve device locked; the water pressure in the supply pipe downstream the valve device detected by a pressure detecting device; and a leak in the water installation determines if a waste the detected water pressure exceeds a predetermined value. In other words, it will leak detection in the water installation evaluated a pressure drop.
Mit diesem Verfahren können wesentlich kleinere Leckagen in der Wasserinstallation als mit den herkömmlichen Leckerfassungssystemen erkannt werden. Auf diese Weise können ein zu hoher Trinkwasserverbrauch und Beschädigungen an Einrichtungen durch austretendes Wasser verhindert bzw. minimiert werden.With this method can much smaller leaks in the water installation than with the usual Leckerfassungssystemen be recognized. This way you can too high drinking water consumption and damage to facilities by escaping water is prevented or minimized.
Zur Bestimmung eines Lecks in der Wasserinstallation können sowohl ein Absolutwert des erfassten Druckabfalls als auch ein zeitlicher Gradient des erfassten Druckabfalls herangezogen werden.to Determining a leak in the water installation can both an absolute value of the detected pressure drop as well as a temporal one Gradient of the detected pressure drop can be used.
In einer bevorzugten Ausgestaltung der Erfindung wird bei einer Bestimmung eines Lecks in der Wasserinstallation das Zuleitungsrohr durch die Ventilvorrichtung aktiv gesperrt.In A preferred embodiment of the invention is in a determination of a leak in the water installation the supply pipe through the Valve device actively disabled.
In einer weiteren Ausgestaltung der Erfindung wird bei einer Bestimmung eines Lecks in der Wasserinstallation einem Benutzer an einer Alarmvorrichtung ein optisches und/oder akustisches Alarmsignal ausgegeben.In Another embodiment of the invention is in a determination a leak in the water installation to a user at an alarm device an optical and / or audible alarm signal is output.
In einer noch weiteren Ausgestaltung der Erfindung kann ferner ein Betrieb eines Verbrauchers in der Wasserinstallation erkannt und ein Wasserverbrauch des erkannten Verbrauchers bei der Bestimmung eines Lecks in der Wasserinstallation berücksichtigt werden.In A still further embodiment of the invention may further include Operation of a consumer detected in the water installation and a water consumption of the detected consumer in the determination of a leak in the water installation.
In einer weiteren Ausgestaltung der Erfindung kann ferner ein maximaler Wasserverbrauch der Wasserinstallation festgelegt, der Wasserverbrauch erfasst und bei Überschreiten des festgelegten maximalen Wasserverbrauchs durch den erfassten Wasserverbrauch ebenfalls ein Leck in der Wasserinstallation erfasst werden.In A further embodiment of the invention may further be a maximum Water consumption of water installation set, water consumption recorded and exceeded of the specified maximum water consumption by the detected Water consumption also detected a leak in the water installation become.
Die Steuereinrichtung ist vorzugsweise die Steuereinrichtung eines Wasserverbrauchszählers am Zuleitungsrohr oder in diese integriert.The Control device is preferably the control device of a water consumption meter on Supply pipe or integrated into this.
Obige sowie weitere Merkmale und Vorteile der Erfindung werden aus der nachfolgenden Beschreibung bevorzugter, nicht-einschränkender Ausführungsbeispiele unter Bezugnahme auf die beiliegenden Zeichnungen besser verständlich.
