Abstract
Description
Dic Scheibe 3 ist auf einen Rohr íh, ZU welchen der Stutzen 11 gehört, mit Muttern 17 verspannt. Zwischen den beiden Scheiben 3, 4 ist auf das Rohr 16 ein Hohlkörper 19 aufgesetzt, der das Rohr 16 umgibt und da- durch einen inneren Ringraum 14 bildet. Der Hohlkörper 19 besteht aus einem Sintermetall. Am in der Figur rechten Ende des Hohlkörpers 19 ist das Rohr 16 geschlossen. The washer 3 is on a pipe, to which the nozzle 11 belongs, clamped with nuts 17. Between the two disks 3, 4 is on the pipe 16 a hollow body 19 is placed, which surrounds the tube 16 and there- by an inner annular space 14 forms. The hollow body 19 consists of a sintered metal. At the right end of the hollow body 19 in the figure, the tube 16 is closed.
Das Rohr 16 weist im Inneren des Hohlkörpers 19 Öffnungen 20 für den Gasdurchtritt auf. Dementsprechend kann das durch den Schlauch 10 herangeführte Schutzgas durch den Stutzen 11, das Rohr 16, die Öffnungen 20 in den Ringraum 14 und von dort durch den Hohlkörper 19 in den äußeren Ringraum 9 strömen. Im äußeren Ringraum 9 bildet sich eine laminare Gasströmung aus, die Lufteinbrüche durch den Schweißspalt 15 verhindert. The tube 16 has in the interior of the hollow body 19 openings 20 for the gas passage on. Correspondingly, this can be brought up through the hose 10 Protective gas through the nozzle 11, the pipe 16, the openings 20 into the annular space 14 and from there flow through the hollow body 19 into the outer annular space 9. In the outer Annular space 9 forms a laminar gas flow, the air penetration through the Weld gap 15 prevented.
An der in der F i g. 1 rechten Scheibe 4 ist mittig ein Zapfen 25 befestigt, der auf seinem dem Hohlkörper 19 zugewandten Ende ein Außengewinde 26 trägt. An der Stirnseite des Zapfens 25 ist eine kugelsegmentartige Ausnehmung 27 als Widerlager für eine Kalotte 28 vorgesehen, die sich am Ende eines Gegenzapfens 29 befindet. Der Gegenzapfen 29 ist an der in F i g. 1 rechten Seite des Hohlkörpers 19 befestigt. Hinter der Kalotte 28 befindet sich ein nach außen gerichteter Radialflansch 30. Auf das Außengewinde 26 des Zapfens 25 ist eine Überwurfmutter 31 aufgedreht, die mit einem nach innen gerichteten Radialflansch 32 den Radialflansch 30 des Gegenzapfens 29 hinterfaßt. Die Teile 25-32 bilden damit ein Universalgelenk begrenzter Schwenkbarkeit. At the in FIG. 1 right disk 4 is a pin 25 in the middle attached, which has an external thread 26 on its end facing the hollow body 19 wearing. A spherical segment-like recess 27 is located on the end face of the pin 25 provided as an abutment for a spherical cap 28, which is at the end of a counter pin 29 is located. The counter pin 29 is at the in F i g. 1 right side of the hollow body 19 attached. Behind the spherical cap 28 there is an outwardly directed radial flange 30. A union nut 31 is screwed onto the external thread 26 of the pin 25, with an inwardly directed radial flange 32, the radial flange 30 of the counter pin 29 behind. The parts 25-32 thus form a universal joint of limited pivotability.
Wenn die Überwurfmutter 31 etwas gelockert ist, kann die Scheibe 4 gegenüber der Scheibe 3 und dem Hohlkörper 19 nach Maßgabe der auf sie einwirkenden, aus der Geometrie des jeweiligen Rohrabschnittes resultierenden Kräfte verschwenken.When the union nut 31 is loosened somewhat, the washer 4 opposite the disc 3 and the hollow body 19 according to the acting on them, pivot forces resulting from the geometry of the respective pipe section.
Bei der dargestellten Ausführung weist die Scheibe 3 außenseitig einen Bügel oder ein Bügelkreuz mit davon abgewinkelten Federzungen 21 auf, die sich an der Innenseite des Rohres abstützen und eine Führung sowie Zentrierung für die Scheibe 4 bilden. In the embodiment shown, the disk 3 has the outside a bracket or a bracket cross with spring tongues 21 angled therefrom, which support themselves on the inside of the pipe and a guide and centering for form the disc 4.
