Den Düsenkopf 2 durchzieht in zentraler Längsrichtung ein erster Kanal 3, der den Eintritt und den Austritt verbindet. Vier zweite Kanäle 4 durchdringen den Düsenkopf 2 in radialer Richtung und schneiden den ersten Kanal 3. Der zentrale Ausgang des ersten Kanals 3 ist mit einer Kegelstrahldüse The nozzle head 2 passes through in central longitudinal direction, a first channel 3, which connects the inlet and the outlet. Four second channels 4 penetrate the nozzle head 2 in the radial direction and intersect the first channel 3. The central outlet of the first channel 3 is provided with a cone jet nozzle
abgeschlossen, ein Überdruckventil 6 fehlt. Alle zweiten Kanäle 4 sind je mit einer Zweigleitung 7 verbunden, die das System bis zu den radialen Düsen (nicht dargestellt) erweitert. Der completed, a pressure relief valve 6 is missing. All second channels 4 are each connected to a branch line 7, which extends the system up to the radial nozzles (not shown). The
Eintrittsbereich des ersten Kanals 3 umfasst ein verzweigten Anschluss 5 an welchem zwei Systemdrücke anliegen können: das Hochdrucksystem (HD) bei ca. 70 bar und das Niederdrucksystem (ND) bei ca. 5 bis 10 bar. Die Feder 10 des ND-Rückschlagventils 6 lässt sich bei ca. 0,5 bar Druck Entry region of the first channel 3 comprises a branched connection 5 at which two system pressures may be applied: the high-pressure system (HD) at about 70 bar and the low-pressure system (ND) at about 5 to 10 bar. The spring 10 of the LP check valve 6 can be at about 0.5 bar pressure
zusammendrücken, wodurch das ND-Rückschlagventil 12 öffnet. Die squeeze, whereby the LP check valve 12 opens. The
Niederdruckflüssigkeit (Chemie) durchströmt die Kanäle des Düsenkopfes 2 und tritt an der zentralen Düse des ersten Kanals 3 aus. Liegt an dem HD- Rückschlagventil 12 ein Systemdruck an, lässt sich die Feder 10 des HD- Überdruckventils 6 zusammendrücken. In diesem Fall strömt das HD-Fluid (Wasser) durch die Kanäle des Düsenkopfes 2, drückt die radialen Low-pressure fluid (chemistry) flows through the channels of the nozzle head 2 and exits at the central nozzle of the first channel 3. If a system pressure is applied to the HD check valve 12, the spring 10 of the HP overpressure valve 6 can be compressed. In this case, the HD fluid (water) flows through the channels of the nozzle head 2, pushing the radial
Überdruckventile 6 auf, strömt aus deren Düsen und gleichzeitig aus der zentralen Öffnung des ersten Kanales 3. Relief valves 6, flows from the nozzles and at the same time from the central opening of the first channel. 3
