Abstract

The nozzle has a nozzle body (1) with nozzle bore (2), twist body (4) and slits. One group of slits (17) is connected permanently upstream to the fluid flow through separate supply channels or other means (12, 13) whilst a spring-loaded valve (9, 10,11) is integrated in the flow path for the second group of slits (16). The valve can be a separate component whose closing part is a cone.

Description

Stand der TechnikState of the art

Es sind Düsen bekannt, bei welchen die Drallschlitze in Gruppen zusammengefasst sind, wobei zumindestens eine Gruppe über ein in der Düse integriertes Stellglied zu- oder abgeschaltet werden kann. In der Anmeldung P 101 23 638.7 wird eine Düse beschrieben, bei der ein federbelasteter Kolben den Zufluss zur 2. Gruppe Drallschütze öffnet, sobald die durch den Druck des Fluids auf den Kolben wirkende Kraft geringfügig die Federkraft übersteigt. Bei geschlossenem Kolben gelangt das Fluid über eine Bohrung im Kolben zur 1. Gruppe Drallschlitze. Bei kleinen Düsen, wie sie z. B. für Ölbrenner verwendet werden, muss die Bohrung im Kolben so klein sein, dass sie gegen Partikel im Fluid sehr empfindlich ist. Zudem ist die Herstellung derart kleiner Bohrungen in der Serienfertigung sehr teuer. Nozzles are known in which the swirl slots are combined in groups are, at least one group via an actuator integrated in the nozzle or can be switched off. In the application P 101 23 638.7 there is a nozzle described, in which a spring-loaded piston the inflow to the 2nd group Swirl contactor opens as soon as the force acting on the piston due to the pressure of the fluid slightly exceeds the spring force. When the piston is closed, the fluid arrives via a hole in the piston to the 1st group of swirl slots. With small nozzles like this z. B. used for oil burners, the bore in the piston must be so small that it is very sensitive to particles in the fluid. The manufacture is also such small holes in series production very expensive.

In der Zeichnung ist 1 Ausführungsbeispiel dargestellt. In the drawing, 1 embodiment is shown.

Beschreibung des ErfindungsbeispielsDescription of the invention example

Die Zeichnung zeigt eine Dralldüse bestehend aus dem Düsenkörper 1, mit der Düsenbohrung 2, wobei der Düsenkörper 1 innen als Hohlkegel 3 ausgebildet ist. Der Drallkörper 4 wird mit seinem kegeligen Teil durch das Schraubteil 5 dichtend in den Hohlkegel 3 gedrückt. Im Schraubteil 5 sitzt die zentrale Bohrung 6, über welche das Fluid in die beiden quer angeordneten Kanäle 7 und 8 strömt. Liegt der Druck des Fluids unter dem Öffnungsdruck der Kugelventils - bestehend aus der Kugel 9, der Feder 10, sowie den Sitz 11 im Schraubteil 5 - geht das Fluid über die beiden Kanäle 7 und 8 zu den axialen Kanälen 12 und 13. Stromab gelangt die Flüssigkeit werter zur ersten Drallschlitzgruppe 14. Der gegenüber liegende Drallschlitz ist wegen der besseren Übersicht nicht dargestellt. Wird der Druck soweit erhöht, dass die Haltekraft der Feder 10 überschritten wird, hebt die Kugel 9 vom Sitz 11 ab und Flüssigkeit kann in die Bohrung 15 strömen. Die zweite Drallschlitzgruppe 16 - wobei wieder nur ein Drallschlitz dargestellt wird - ist über die Bohrung 17 mit der Bohrung 15 verbunden. Somit wird durch eine geringe Druckerhöhung eine zweite Drallschlitzgruppe zugeschaltet, entsprechend der Auslegung der Feder 10. Die Drallschlitze der Gruppe 16 sind kürzer ausgeführt als jene der Gruppe 14. Die Schlitze der Gruppe 16 sind stromauf verschlossen, daher kann keine Flüssigkeit einströmen, solange das Kugelventil nicht geöffnet hat. The drawing shows a swirl nozzle consisting of the nozzle body 1 , with the nozzle bore 2 , the nozzle body 1 being designed as a hollow cone 3 on the inside. The swirl body 4 is pressed with its conical part into the hollow cone 3 in a sealing manner by the screw part 5 . In the screw part 5 sits the central bore 6 , through which the fluid flows into the two transversely arranged channels 7 and 8 . If the pressure of the fluid is below the opening pressure of the ball valve - consisting of the ball 9 , the spring 10 , and the seat 11 in the screw part 5 - the fluid passes through the two channels 7 and 8 to the axial channels 12 and 13 . Downstream, the liquid reaches the first swirl slot group 14 . The opposite swirl slot is not shown because of the better overview. If the pressure is increased to such an extent that the holding force of the spring 10 is exceeded, the ball 9 lifts off the seat 11 and liquid can flow into the bore 15 . The second swirl slot group 16 - again with only one swirl slot being shown - is connected to the bore 15 via the bore 17 . A second swirl slot group is thus activated by a slight pressure increase, in accordance with the design of the spring 10 . The swirl slots of group 16 are shorter than those of group 14 . The slots in group 16 are closed upstream, so no liquid can flow in until the ball valve has opened.

Die Zuführung des Fluids zur permanent beaufschlagten Gruppe 14 kann auch in der Weise erfolgen, dass der Drallkörper 4 einen geringeren Durchmesser aufweist als die entsprechende Aufnahmebohrung im Düsenkörper 1. Ebenso kann das Kugelventil als separates Bauteil in die Düse eingesetzt werden. Das Schließteil kann eine Kugel sein, oder auch als Kegel ausgebildet werden. Auf diese Weise ist es möglich, durch unterschiedlichen Hub des Ventilkegels für die zweite Drallschlitzgruppe eine zusätzliche Regelung der Fluidströmung zu erzielen. The fluid can also be supplied to the permanently loaded group 14 in such a way that the swirl body 4 has a smaller diameter than the corresponding receiving bore in the nozzle body 1 . The ball valve can also be used as a separate component in the nozzle. The closing part can be a ball, or can also be designed as a cone. In this way, it is possible to achieve additional control of the fluid flow by means of different valve cone stroke for the second swirl slot group.
