Abstract
Description
Die Erfindung betrifft eine kombinierte Durchfluss- und Druckmesseinrichtung für Wasser mit den Merkmalen des Anspruchs 1.The invention relates to a combined Flow and pressure measuring device for water with the features of claim 1.
Beregnungsanlagen stellen je nach Auslegung unterschiedliche Anforderungen an Druck und Menge des Brauchwassers. Je nach verwendetem Sprenglertyp, Anzahl der Sprengler und den Zuleitungsverlusten sind an einer Zuleitung Mindestdrücke bei gefordertem Durchflussvolumen vorauszusetzen.Irrigation systems depend on Interpretation of different pressure and quantity requirements Domestic hot water. Depending on the type of sprinkler used, the number of sprinklers and the line losses are minimum pressures on a line required flow volume.
Aufgabe der Erfindung ist es, eine kombinierte Durchfluss- und Druckmesseinrichtung für Wasser, insbesondere für Wasser einer Beregnungsanlage, zu schaffen, mit der Druck und Menge des Brauchwassers an einer Zuleitung einfach und schnell ermittelt werden kann.The object of the invention is a combined flow and Pressure measuring device for Water, especially for Water a sprinkler to create, with the pressure and quantity of service water can be determined quickly and easily on a supply line can be.
Die Lösung erfolgt mit einer kombinierten Durchfluss- und Druckmesseinrichtung für Wasser, insbesondere für Wasser einer Beregnungsanlage, mit den Merkmalen des Anspruchs 1.The solution is a combined flow and pressure measuring device for Water, especially for Water of an irrigation system, with the features of claim 1.
Gemäß der Erfindung ist eine kombinierte Durchfluss- und Druckmesseinrichtung für Wasser, insbesondere für Wasser einer Beregnungsanlage, mit einer Armatur versehen, an der in Reihe nach einem Zufluss die Druckmesseinrichtung und eine einstellbare Drossel und nach der Armatur und vor einem Abfluss die Durchflussmesseinrichtung geschaltet sind. Der Zufluss der Armatur der erfindungsgemäßen, kombinierten Durchfluss- und Druckmesseinrichtung wird mit einem handelsüblichen Bajonett-, Steck- oder Schraubverschluss mit der Zuleitung für Brauchwasser, z. B. aus einer haushaltsüblichen Frischwasserleitung, verbunden. Bei geschlossener Drossel, d. h. bei Durchfluss = Null durch die Armatur, zeigt die Druckmesseinrichtung den maximal möglichen Zuleitungsdruck in der Zuleitung für Brauchwasser, nämlich den Staudruck, an. Bei geöffneter Drossel zeigt die der Armatur nachgeschaltete Durchflussmesseinrichtung den Durchfluss durch die Armatur und die Druckmesseinrichtung den statischen Druck in der Zuleitung für Brauchwasser an, wobei bei völlig geöffneter Drossel der maximal mögliche Durchfluss mit dem zugehörigen statischen Druck angezeigt werden. Die erfindungsgemäße, kombinierte Durchfluss- und Druckmesseinrichtung ermöglicht es für unterschiedliche Durchflussmengen, die für die Auslegung einer Beregnungsanlage erforderlichen Daten direkt abzulesen und danach die Beregnungsanlage zuverlässig auszulegen. Die erfindungsgemäße, kombinierte Durchfluss- und Druckmesseinrichtung ist einfach und schnell zu handhaben.According to the invention, a combined flow and pressure measuring device for Water, especially for Water from an irrigation system, provided with a fitting on which in series after an inflow the pressure measuring device and an adjustable Throttle and after the valve and before a drain the flow measuring device are switched. The inflow of the valve of the combined flow according to the invention and pressure measuring device is with a commercially available bayonet, plug or Screw cap with the supply for service water, e.g. B. from a household Fresh water pipe, connected. With the throttle closed, i. H. at flow = zero through the valve, shows the pressure measuring device the maximum possible Line pressure in the line for service water, namely the Back pressure, on. When open Throttle shows the flow measuring device downstream of the valve the flow through the valve and the pressure measuring device static pressure in the supply line for process water, whereby at completely open Throttle the maximum possible Flow with the associated static pressure are displayed. The inventive, combined Flow and pressure measuring device allows for different flow rates, the for the design of a sprinkler system directly read and then reliably design the irrigation system. The inventive, combined Flow and pressure measuring device is easy and quick to use.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist als einstellbare Drossel ein Schieber vorgesehen, mit dem der Durchfluss durch die Armatur besonders einfach vollständig sperrbar ist.According to a preferred embodiment of the According to the invention, a slide is provided as an adjustable throttle, with which the flow through the valve can be completely completely blocked is.
Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung weist die Durchflussmesseinrichtung eine Feder, einen Kolben und eine Öffnung zum Abfluss auf. Der gegen die Wirkung der Feder verstellbare Kolben steuert die Öffnung zum Abfluss in Abhängigkeit vom anliegenden Druck. Die Feder kann vorzugsweise so eingestellt sein, dass mit ihr Rohrleitungsverluste in der Beregnungsanlage simuliert werden können.According to another preferred The flow measuring device has an embodiment of the invention a spring, a piston and an opening for drainage. The piston adjustable against the action of the spring controls the opening Outflow depending from the applied pressure. The spring can preferably be set in this way be that with her pipe losses in the irrigation system can be simulated.
Die Erfindung wird im Folgenden anhand eines bevorzugten Ausführungsbeispiels dargestellt. Es zeigt:The invention is explained below of a preferred embodiment shown. It shows:
