Description
Zwischen dem Sammler oder Verteiler eines Wärmeaustauschers und einem Rohr festgeschweißte Muffe Die Erfindung bezieht sich auf eine Muffe, die mit ihrem einen Ende an einem Sammler oder Verteiler eines Wärmeaustauschers und mit ihrem anderen Ende an einem Rohr festgeschweißt ist.Between the collector or distributor of a heat exchanger and a Pipe welded socket The invention relates to a socket with its one end to a header or manifold of a heat exchanger and to its the other end is welded to a pipe.
Bei den bekannten Muffen bereitet es immer gewisse Schwierigkeiten, die Verbindung zwischen ihnen und dem Rohr herzustellen, da der Rand des letzteren ausgefeilt werden muß, um einen etwa formschlüssigen Sitz des Rohres auf der Muffe zu erzielen. Diese Arbeit wird zusätzlich einerseits dann erschwert, wenn die Muffe schlecht zugänglich ist, und andererseits, wenn das Rohr nicht im rechten Winkel, sondern schräg von der Muffe abgeht. In diesem Fall stellt der Rand eine komplizierte und daher nur schwer herstellbare Raumkurve dar.With the known sleeves, there are always certain difficulties establish the connection between them and the pipe as the edge of the latter Must be polished in order to ensure that the pipe is seated positively on the socket to achieve. This work is also made more difficult on the one hand when the socket difficult to access, and on the other hand, if the pipe is not at right angles, but goes off at an angle from the socket. In this case, the edge presents a complicated one and therefore difficult to produce space curve.
Diese Nachteile werden durch die Erfindung beseitigt. Diese besteht darin, daß das mit dem Rohr verbundene Ende der Muffe in ein kugelförmiges Anschlußstück übergeht, an welches das Rohr mittels einer Schweißnaht in jedem gewünschten Winkel zu befestigen ist. Dadurch entfällt jegliche Bearbeitung des Rohrendes, und zwar auch dann, wenn das Rohr schräg zur Achse der Muffe an dieser befestigt werden soll. Hinzu kommt, daß die Schweißnaht bei der erfindungsgemäßen kugelförmigen Ausbildung des Muffenendes immer kreisförmig und deshalb kürzer als jede andere Form ist, so daß die für den Schweißvorgang erforderliche Zeit entsprechend gering ist. Außerdem ist auch bei schräger Anbringung des Rohres der gesamte Berührungsbereich zwischen diesem und der Muffe gut zugänglich. Bei der bisherigen Ausbildung bereitet es in diesem Falle Schwierigkeiten, die Schweißnaht in den spitzen Winkel zwischen Rohr und Muffe zu legen.These disadvantages are eliminated by the invention. This exists in that the end of the sleeve connected to the pipe into a spherical connector merges, to which the pipe by means of a weld seam at any desired angle is to be attached. This eliminates any processing of the pipe end, namely even if the pipe is to be fastened to the sleeve at an angle to the axis of the sleeve. In addition, the weld seam in the spherical design according to the invention of the socket end is always circular and therefore shorter than any other shape, like this that the time required for the welding process is correspondingly short. aside from that is the entire contact area between easily accessible to this and the socket. In the previous training it prepares in In this case difficulties in welding the seam in the acute angle between the pipe and to lay sleeve.
Es ist zweckmäßig, wenn die Muffe an ihrem mit dem Sammler oder Verteiler verbundenen hinteren Ende in bekannter Weise zum Eingriff in eine Bohrung zapfenartig ausgebildet und durch eine Kehlnaht festschweißbar ist.It is useful if the sleeve is connected to the collector or distributor connected rear end in a known manner for engagement in a bore pin-like is formed and can be welded in place by a fillet weld.
Zur weiteren Verdeutlichung der Erfindung wird auf die Zeichnung verwiesen, die ein Ausführungsbeispiel der Erfindung wiedergibt.To further clarify the invention, reference is made to the drawing, which reproduces an embodiment of the invention.
Darin sind mit 10 zapfenartig in den Sammler oder Verteiler 11 eines Wärmeaustauschers eingeschweißte Muffen bezeichnet, die mit einem kugelförmigen Ende 12 versehen sind, in welches ein Rohr 13 mittels einer Naht 14 eingeschweißt ist. In der Zeichnung sind eine rechtwinklige Abzweigung, eine schräge Abzweigung des Rohres 13 von der Muffe 10 und eine solche Verbindung dargestellt, bei der diese Teile koaxial zueinander liegen.In it are 10 like a pin in the collector or distributor 11 one Heat exchanger welded sleeves referred to with a spherical End 12 are provided, into which a tube 13 is welded by means of a seam 14 is. In the drawing there is a right-angled branch, an oblique branch of the pipe 13 of the socket 10 and such a connection shown in which this Parts are coaxial with each other.
Während in der Zeichnung die linke Muffe 10 zu dem Sammler oder Verteiler hin gleiche Wandstärke aufweist, ist die obere linke Muffe 10, wie in dem teilweisen Schnitt erkennbar ist, an ihrem Ansatzende in der Wandstärke so reduziert, daß dieses Ende 4 bis zu der gezeigten Tiefe zapfenartig und anschließend in die Bohrung 2 paßt.While in the drawing the left sleeve 10 has the same wall thickness towards the collector or distributor, the upper left sleeve 10, as can be seen in the partial section, is reduced in wall thickness at its starting end so that this end 4 up to that shown Depth like a pin and then fits into the hole 2.
