Description
Spritzdüse zum Zerstäuben an .he und ähnlichen Flüssigkeiten Die Erfindung betrifft eine Spritzdüse zum Zerstäuben von Farbe und ähnlichen Flüssigkeiten in flachem. Strahl mit einem in einer Wandungsausbauchung vorgesehenen Einschnitt.Spray nozzle for atomizing .he and similar liquids The invention relates to a spray nozzle for atomizing paint and similar liquids in flat. Beam with an incision provided in a wall bulge.
Solche Düsen werden z. B. verwendet zum Zerstäuben von Feuerlöschmitteln. Dabei ist die kugelkappenförmige Wölbung ,am Boden von tiefen Bechern vorgesehen, -die auf die Druckleitung aufgeschraubt sind. Diese Bauart ist jedoch nicht an Geräten verwendbar, mit denen z. B. Farbe unter Drücken von 15 o und mehr atü ausgespritzt wird. Denn die dort erforderlichen Schlitze sind so klein, @daß es unmöglich ist, die sich dabei ergebenden kleinen Becher noch genügend dicht zu befestigen.Such nozzles are z. B. used for atomizing fire extinguishing agents. The spherical cap-shaped bulge is provided on the bottom of deep cups that are screwed onto the pressure line. However, this design can not be used on devices with which z. B. Color is sprayed out by pressing 1 5 o and more atü. Because the slots required there are so small that it is impossible to fasten the resulting small cups sufficiently tightly.
Das fast allein verwendbare auswechselbare Element ist an solchen Geräten die planparallele Vorsatzplatte. Die Herstellung von ganz feinen Schlitzen in solchen Vorsatzplattem. durch Bohren und Stoßen ist jedoch sehr schwierig und entsprechend teuer.The replaceable element that can be used almost alone is at such The plane-parallel attachment plate. The production of very fine slots in such Vorsatzplattem. however, drilling and poking is very difficult and correspondingly expensive.
Gemäß der Erfindung ist deshalb vorgesehen, -daß bei Spritzdüsen mit auswecliselbarer, planparalleler Vorsatzplatte die Mitte ,der Platte eine den Einschnitt tragende,, in Spritzrichtung liegende kugelschalenförmige Wölbung innerhalb der parallelen Begrenzungsebenen der Vorsatzplatte aufweist. Durch diese Ausbildung wird erreicht, daß in den Vorsatzplatten die Schlitze mit Hilfe einer Kreissäge o. dgl. billig und. doch genau hergestellt werden können, ohne daß die Platten Vorsprünge aufweisen, welche die parallelen Endflächen überragen und dadurch. die Anbringung an der Düse erschweren.According to the invention it is therefore provided that with spray nozzles Removable, plane-parallel facing plate is the center, the plate one is the incision load-bearing, spherical shell-shaped curvature lying in the direction of spraying within the having parallel delimitation planes of the facing plate. Through this training it is achieved that the slots in the facing plates with the help of a circular saw or the like cheap and. but can be made accurately without the plates protruding have which protrude beyond the parallel end faces and thereby. the attachment difficult at the nozzle.
In der Zeichnung ist .ein Ausführungsbeispiel einer gemäß der Erfindung ausgebildeten Spritzdüse dargestellt.In the drawing is .ein embodiment of one according to the invention trained spray nozzle shown.
Abb. i zeigt einen Achsschritt durch die Spritzdüse in einer ,gegenüber den üblichen Düsenabmessungen stark vergrößerten Darstellung: Abb. 2 zeigt in demselben Mäße die entgegen der Spritzrichtung geselhene Vorsatzplatte. Im: Düsenkörper i ist ,eine Düsenverschlußnadel 3 geführt; welche !mit ihrem kegeligen Ende 33 auf einem entsprechenden Bund i i .des Düsenkörpers unter Federbelastung aufsitzt. Das Spritzgut wird durch einen Mitt:elkanal 3 i der Düsennadel und Abzweigkanäle 32 in .den Hohlraum, des Düsenkörpers einge-,drückt und lüftet beim Überschreiten eines der Federvorspannungentsprechendem Druckes die Nadel 3 mit ihrer Sitzfläche33 von der Fläche i i ab, so daß das Spritzgut austritt.Fig. I shows an axial step through the spray nozzle in one, opposite the usual nozzle dimensions greatly enlarged representation: Fig. 2 shows the same If the faceplate seen against the direction of spraying. In: nozzle body i is guided, a nozzle valve needle 3; which! with their conical end 33 a corresponding collar i i. of the nozzle body is seated under spring load. That The spray material is fed through a central channel 3 i of the nozzle needle and branch channels 32 into .the cavity of the nozzle body, pressed and vented when crossing a the spring preload corresponding pressure, the needle 3 with its seat 33 of the area i i from, so that the spray material emerges.
Auf die Stirnfläche des: Düsenkörpers i ist eine planparallele Vorsatzplatte 4 mit Hilfe einer überwurfmutter 2 festgespannt. In dieser Vorsatzplatte ist Idas Mittelstück dünnwandiger als die übrige Platte ausgebildet und besitzt die Form einer kugelschalenförmigen Wölbung, die entweder durch spanabhebende oder sparlose Formgebung erhalten werden kann.On the face of the nozzle body i is a plane-parallel attachment plate 4 tightened with the help of a union nut 2. In this faceplate is Idas The middle piece is thinner-walled than the rest of the plate and has the shape a spherical shell-shaped vault, which is either by cutting or non-cutting Shaping can be obtained.
Quer durch diese Wölbung 41 ist mit einem kreisförmigen schmälen Sägeblatt ein Schnitt gelegt, der in der Wölbung ¢i die rechteckige Durchtrittsöffnung 43 freilegt. -Die kugelschalenförmige Wölbung, die im gezeichneten Beispiel die Begrenzungsebenen ,der Vorsatzplatte q. nicht überschreitet, kann auch z. B. über diese Begrenzung hinaus vorgetrieben werden. Man kann damrden Schnitt durch die Kuppe auch mit einer geraden Säge ausführen, ohne dabei -den dickwandigen Teil der Vorsatzplatte anzuschneiden, hat aber dabei ;den Nachsteil, daß die Kuppe und die darin befindliche Auslaßöffnung viel mehr Beschädigungen ausgesetzt sind.Across this bulge 41 is a circular narrow saw blade a section is laid, which in the curvature [i] the rectangular passage opening 43 exposed. -The spherical shell-shaped curvature, which in the example shown is the boundary planes , the facing plate q. does not exceed, z. B. over this limitation be driven beyond. You can cut through the top with a make a straight saw without cutting the thick-walled part of the facing plate, but has the disadvantage that the dome and the outlet opening located in it are exposed to much more damage.
