Description
Im allgemeinen sind, bei Beregnungsanlagen die Regner an fest verlegte oder behelfsmäßig verdeckte Feldleitungen angeschlossen, wobei ein am Anfang der Feldleitung vorgesehenes Absperrventil die Wasserzufuhr regelt. Wird somit in Betriebnahme der Regneranlage das Absperrventil geöffnet, so ergibt sich namentlich bei langen Feldoder Regnerleitungen der Mißstand, daß das Wasser zunächst drucklos aus den Regnern ausfließt und erst langsam den für den Umlauf- oder Schwenkerantrieb der Regner erforderlichen Druck erreicht. Durch dieses drucklose Austreten des Wassers aus den Regnern bilden sich somit leicht Wasserpfützen in den Kulturen, in der Nähe der Regner, die auch zu Auskolkungen oder namentlich am Hang zu einem Wegschwemmen des Erdreichs führen können.In general, in irrigation systems the Sprinklers connected to permanently installed or temporarily covered field lines, with an am The shut-off valve provided at the beginning of the field line regulates the water supply. Is thus put into operation the shut-off valve of the sprinkler system is open, this results in particular in the case of long field or Sprinkler pipes the problem that the water initially flows out of the sprinklers without pressure and only slowly the pressure required for the rotary or swivel drive of the sprinklers achieved. This pressure-free discharge of the water from the sprinklers thus forms easily Puddles of water in the crops, near the sprinklers, which also lead to scouring or by name can lead to the soil being washed away on a slope.
Diese Mangel werden gemäß der Erfindung dadurch behoben, daß bei einer Beregnungsanlage mit an einer Regnerleitung angeschlossenen Einzelregnern für ununterbrochenen Betrieb jedem Regner ein Druckregelventil vorgeschaltet ist. Durch die Einschaltung dieser Druckregelventile kann das Wasser aus den Regnern erst dann, austreten, wenn in der Regnerleitung der Betriebsdruck, auf den die Druckregel ventile eingestellt sind, erreicht ist. In gleicher Weise können auch den an sich in Beregnungsanlagen vorgesehenen Sicherheitsventilen Regner nachgeschaltet sein, um das bei plötzlichen Drucksteigerungen in der Leitung aus diesenThese shortcomings are remedied according to the invention in that with a sprinkler system Individual sprinklers connected to a sprinkler line for uninterrupted operation each A pressure control valve is connected upstream of the sprinkler. By switching on these pressure regulating valves this can The water from the sprinklers only emerges when the operating pressure in the sprinkler line has reached the Pressure regulating valves are set, is reached. In The safety valves provided per se in sprinkling systems can also be used in the same way Sprinklers can be connected downstream in the event of sudden pressure increases in the line from these
Sicherheitsventilen atistretende Wasser auf eine größere Fläche zu verteilen und Ausspülungen des Bodens zu verhindern.Safety valves leak water on a to distribute a larger area and prevent the soil from being washed away.
An sich ist es bekannt, bei Beregnungs- und Feuerlöschanlagen, für stoßweisen Betrieb den Regnern Druckwindkessel anzuordnen, wobei in die Zuleitung zu dem Regner ein Überdruckventil eingeschaltet ist, das den Überdruck in dem Druckwindkessel und damit den stoßweisen Austritt des Wassers aus dem Regner bestimmt. Diese Einrichtungen können jedoch für einen ununterbrochenen Betrieb der Regner nicht verwendet werden.It is known per se for sprinkling and fire extinguishing systems for intermittent operation Arrange sprinklers pressure air tanks, with a pressure relief valve in the supply line to the sprinkler is switched on, the overpressure in the pressure air tank and thus the intermittent exit of the Water from the sprinkler determined. However, these facilities can be used for uninterrupted periods Operation of the sprinkler not used.
