Die Erfindung betrifft eine Düse, die zum Absprühen von Hochdruckflüssigkeit dient.The invention relates to a nozzle which is used for spraying off high pressure liquid serves.
Zum Stand der Technik gehört es, Düsen aus hochverschleißfestemThe state of the art includes nozzles made of highly wear-resistant
Material, beispielsweise aus Keramik oder aus Borkarbid oder aus Wolframkarbid herzustellen, um den Düsenverschleiß zu senken undMaterial, for example from ceramic or from boron carbide or from Manufacture tungsten carbide to reduce nozzle wear and

gen der Härte und Sprödigkeit des Materials schwierig und ihre Bearbeitung daher aufwendig und teuer.The hardness and brittleness of the material make them difficult to work with therefore complex and expensive.
Ziel der Erfindung ist es, eine zum Absprühen von Hochdruckflüssigkeit dienende Düse zu schaffen, die sich durch hohe Standzeit auszeichnet und einfacher und damit auch preiswerter herzustellen ist.The aim of the invention is to provide one for spraying off high pressure liquid To create serving nozzle, which is characterized by a long service life and easier and therefore cheaper to manufacture is.
Die Erfindung löst das Problem durch Beschichten der Düsenbnhrung und überzieht die Oberfläche dieser Bohrung mit Titankarbid, Titannitrit, Wolframkarbid oder Aluminiumoxyd in einer Dicke von 2 bis 10, vorzugsweise jedoch 5 Micrometern. Düsen dieser Art zeichnen sich, wie praktische Versuche ergeben haben, dur-h erheblich größere Standzeiten aus, und zwar selbst bei Flüssigkeitsdrücken von 2000 bar, und haben einen besseren Wirkungsgrad.The invention solves the problem by coating the nozzle bore and covers the surface of this hole with titanium carbide, titanium nitride, tungsten carbide or aluminum oxide to a thickness of 2 up to 10, but preferably 5 micrometers. Draw nozzles of this type As practical tests have shown, they have a considerably longer service life, even at liquid pressures of 2000 bar, and have a better efficiency.
Ihre Düsenkörper können nach einem weiteren Erfindungsmerkmal
Hartmetall oder aus einem Werkraugstahl gefertigt werden, der eine
Rockwellhärte von 50 bis 62 HRC aufweist. Sie sind allein wegen ihrer Materialkosten und, bei der Verwendung von Werkzeugstahl,
wegen der geringeren Fertigungskosten preiswerter als Düsen eines anderen hochverschleißfesten Materials.Your nozzle body can according to a further feature of the invention
Tungsten carbide or a rough steel with a Rockwell hardness of 50 to 62 HRC. They are cheaper than nozzles made from another highly wear-resistant material simply because of their material costs and, if tool steel is used, because of the lower production costs.

Ein Ausfuhrungsbeispiel der erfindungsgemäßen Düse ist in der Abbildung dargestellt und im folgenden Beschreibungsteil näher erläutert. An exemplary embodiment of the nozzle according to the invention is shown in the figure and explained in more detail in the following part of the description.
Die mit 1 bezeichnete Düse dient zum Absprühen von Hochdruckflüssigkeit. Sie besitzt eine Düsenbohrung 2 und einen mit einem Gewinde 3 versehenen Umfangsabschnitt im Bereich ihres Einlaufendes. An diesen Gewindeabschnitt 3 schließt sich ein sechskantförmiger Bund 4 an, der zum Ansetzen eines Werkzeuges zur Montage oder Demontage der Düse 1 dient. Im Austrittsbereich hat die Düse 1 zylindrischen Querschnitt und besitzt hier einen sich trichter- C . förmig nach außen erweiternden Auslauf 5 , der zentrisch zur DüThe nozzle marked 1 is used for spraying high pressure liquid. It has a nozzle bore 2 and a circumferential section provided with a thread 3 in the region of its inlet end. This threaded section 3 is followed by a hexagonal collar 4, which is used to attach a tool for assembling or disassembling the nozzle 1. In the outlet area, the nozzle 1 has a cylindrical cross-section and here has a funnel- C . shaped outwardly widening outlet 5, which is centric to the Dü

Sie hat eine Dicke von 2 bis 10 Micrometern, vorzugsweise jedoch von 5 Micrometern. Hartmetall oder ein Werkzeugstahl mit einer Rockwellhärte von 50 bis 62 HRC bilden den Düsenkörper la.Senbohrung 2 is and connects to this hole 2. The nozzle hole 2 is provided with a coating made of titanium carbide, titanium nitrite, tungsten carbide or aluminum oxide. she has a thickness of 2 to 10 micrometers, but preferably 5 micrometers.
