Vollkegeldüse zum Versprühen von FlüssigkeitenFull cone nozzle for spraying liquids
Die Neuerung bezieht sich auf eine Vollkegeldüse zum Versprühen von Flüssigkeiten, bestehend aus einem Düsengehäuse und einem darin angeordneten Drallkörper, der in gleichmäßigem radialem Abstand von seiner Mittelachse mehrere Drallkanäle aufweist. The innovation relates to a full cone nozzle for spraying of liquids, consisting of a nozzle housing and a swirl body arranged therein, which has several swirl channels at a uniform radial distance from its central axis.
Bekannte Vollkegeldüsen mit Drallkörper, bei dem die Kanäle am Umfang angeordnet sind und durch Fräsen erzeugt werden, weisen den wesentlichen Nachteil einer sehr ungleichmäßigen Fliissigkeitsverteilung auf. Wie Messungen ergeben haben, tritt jeweils in zwei um 13g° versetzten Zonen des Vollkegels eine besonders starke Flüssigkeitsdichte auf. Als Ursache dieser ungleichmäßigen Flüssigkeitsverteilung wurde die Formgebung des Drallkörpers erkannt.Well-known full cone nozzles with swirl body, in which the channels on the circumference are arranged and are produced by milling, have the essential disadvantage of a very uneven distribution of liquid on. As measurements have shown, there is a particularly high density of liquid in two zones of the full cone offset by 13g ° on. The shape of the swirl body was recognized as the cause of this uneven liquid distribution.
Aufgabe der vorliegenden Neuerung ist es, einen Orallkörper zu schaffen, mit dem sich der beschriebene Nachteil der bekanntenThe task of the present innovation is to provide an oral body create, with the described disadvantage of the known

Vollkegeldiisen vermeiden läßt. Gemäß dem Grundgedanken der Neuerung wird das Problem bei eitler Vollkegel düse der eingangs genannten Art dadurch gelöst, daß als Drallkanäle geschlossene Bohrungen dienen, die gegenüber der Mittelachse des Drallkörpers in tangentialer Richtung geneigt angeordnet sind.Lets avoid full cone nozzles. According to the basic idea of the innovation the problem with vain full cone nozzle of the type mentioned at the beginning solved in that closed bores are used as swirl channels which are tangential to the central axis of the swirl body are arranged inclined.
Nach einem weiteren Merkmal der Neuerung sind im Drallkörper drei Drallkanalbohrungen, jeweils um 120° zueinander versetzt, angeordnet, wobei der Neigungswinkel der Drallkanalbohrungen zur Mittelachse des Drallkörpers etwa 30° beträgt.Another feature of the innovation is that there are three in the swirl body Swirl channel bores, each offset from one another by 120 °, the angle of inclination of the swirl channel bores to the central axis of the swirl body is about 30 °.
Durch die neuerungsgemäßen Drallkörper mit drei Drallbohrungen ist es möglich, eine rotationssymmetrische Flüssigkeit sbeaufschlagur.g zu erzeugen. Dies ist überall da - insbesondere bei sehr kleinen Düsen, bei denen man bisher aus verschiedenen Gründen der Meinung war, geschlossene Drallbohrungen nicht anbringen zu können - von entscheidender Wichtigkeit, wo es darauf ankommt, eine gleichmäßige Flüssigkeitsverteilung zu garantieren. Ein weiterer wesentlicher Vorteil der neuerungsgemäßen Düse besteht darin, daß durch einfaches Umdrehen des Drallkörpers der Strahlwinkel des austretenden Flüpsi nkeiti-.kegels von 45° auf 6o° verändert werden V.ann.The swirl body according to the innovation with three swirl bores is it is possible to use a rotationally symmetrical fluid sbeaufschlagur.g to create. This is there everywhere - especially with very small nozzles, which have previously been of opinion for various reasons was not to be able to make closed swirl holes - of decisive importance where it is important, a uniform To guarantee liquid distribution. Another essential one The advantage of the nozzle according to the invention is that, by simply turning the swirl body around, the jet angle of the exiting Flüpsi nkeiti-cone can be changed from 45 ° to 60 ° V.ann.

Wie aus der Zeichnung ersichtlich, besteht die neuerungsgemäße Vollkegeldüse aus einem Düsengehäuse 10 mit Sechskant 11 und Gewinde 12 zum Einschrauben in eine Rohrleitung oder dgl. Die konische Austrittsbohrung d«r Düse ist mit 13 bezeichnet. In einem zweifach ab_,osetzten zylindrischen Innenraum 14 de·". Diisengehäuses 10 ist ein Drallkörper 13 eingesetzt, der sich mit einer konischen Fläche 16 an einem Bund 17 im DUsengehäuse abstützt. Die axiale Fixierung des Drallkörpers 15 erfolgt durch eine Hmbördelung 18, die nach Einsetzen des Drallkörpers im Dusengehäuse 10 vorgenommen wird. Dadurch kann vorteilhaft eine kurze Bauweise der Düse und damit gegenüber Düsen, bei denen der Drallrörper durch einen Spannstift gesichert ist, eine nicht unerhebliche Materialersparnis erzielt werden. Der Drallkörper besitzt eine zentrale Bohrung 19, die koaxial zu der Düsenaustrittsbohrung 13 verläuft.As can be seen from the drawing, the full cone nozzle according to the innovation consists of a nozzle housing 10 with hexagon 11 and Thread 12 for screwing into a pipeline or the like. The conical outlet bore of the nozzle is denoted by 13. In a double ab_, offset cylindrical interior 14 of the ". Diisengehäuses 10, a swirl body 13 is used, which is supported with a conical surface 16 on a collar 17 in the D-nozzle housing. The swirl body 15 is axially fixed by a hem flange 18, which after insertion of the swirl body in the nozzle housing 10 is made. As a result, a short design of the nozzle and thus compared to nozzles in which the Swirl body is secured by a dowel pin, a not inconsiderable material saving can be achieved. The swirl body has a central bore 19 which is coaxial with the nozzle outlet bore 13 runs.
