Description
GEORG FISCHER AKTIENGESELLSCHAFT Schaffhausen (Schweiz) Schweissverbindung
für zwei Rohrleitungselemente
Der Nachteil einer derartigen Verbindung besteht darin, dass beim
Zusamnenstossen der beiden Elemente
Die erfindungsgemässe Schweiss-Verbindung weist diesen Nachteil nicht auf und sie ist dadurch gekennzeichnet, dass ein erstes Rohrleitungselement eine dem Aussendurchmesser eines zweiten einzuschiebenden Elementes entsprechende abgesetzte zylindrische Bohrung mit einer senkrecht zur Verbindungsachse stehenden Anschlagfläche aufweist, in der eine kreisringförmige Nute angeordnet ist. The weld joint according to the invention does not have this disadvantage and it is characterized in that a first pipeline element is a offset corresponding to the outer diameter of a second element to be inserted cylindrical bore with a stop surface perpendicular to the connection axis has, in which an annular groove is arranged.
Die Zeichnung zeigt zwei Ausführungsbeispiele der beschriebenen Verbindung und zwar : Fig. 1 einen Längsschnitt durch die beiden Rohrleitungselemente gemäss einer ersten Ausführungsform während des Heizvorgangs und Fig. 2 einen Längsschnitt durch die beiden Rohrleitungselemente einer hergestellten Schweiss-Verbindung gemäss einer weiteren Ausführungsform. Die Fig. 1 zeigt, wie beispielsweise die zu verbindenden Enden von zwei Rohrleitungselementen 1 und 5, gemäss einer » ersten Ausführungsformg in einer an sich bekannten Heizvorrichtung 1, die nicht Gegenstand der vorliegenden Erfindung ist, unmittelbar vorgängig des Verschweissens gleichzeitig erhitzt werden können. Es könnte indessen irgendeine andere geeignete Methode des Erhitzens angewandt werden. The drawing shows two exemplary embodiments of the connection described namely: FIG. 1 shows a longitudinal section through the two pipeline elements according to FIG a first embodiment during the heating process and FIG. 2 shows a longitudinal section through the two pipeline elements of a welded connection made according to another embodiment. Fig. 1 shows how, for example, to be connected Ends of two pipe elements 1 and 5, according to a »first embodiment in a per se known heating device 1, which is not the subject of the present Invention is to be heated at the same time immediately prior to welding can. However, any other suitable method of heating could be used will.
In Fig. 1 weist das in einen hülsenförmigen, linksseitigen Teil der Heizvorrichtung 1 einsteckbare Ende eines Kunststoffrohres 2 mit einem Inndurchmesser 9 am vorderen Ende mit einer senkrecht zur Verbindungsachse 18 stehenden Stirnfläche 3 einen Absatz 4 geringeren Durchmessers auf. In Fig. 1 this has in a sleeve-shaped, left-hand part of the Heating device 1 insertable end of a plastic pipe 2 with an inner diameter 9 at the front end with an end face perpendicular to the connecting axis 18 3 a paragraph 4 of smaller diameter.
In einem zweiten Rohrleitungelement 5, dessen Innendurchmesser oder Bohrung 10 demjenigen des Rohres 2 entsprechen kann, ist eine dem Aussendurchmesser 6 des Rohres 2 entsprechende abgesetzte Bohrung 7 vorgesehen mit zur Verbindungsachse 18 senkrecht stehender Stirnfläche 8. In der letzteren ist eine kreisringförmite Nute 11 vorgesehen, deren äusserer Durchmesser angenähert dem Durchmesser der Bohrung 7, bzw. dem Aussendurchmesser 6 des Rohres 2 entspricht, und deren innerer Durchmesser grösser als die Bohrung des Rohres 2, bzw. des Rohrleitungselementes 5 ist. In a second pipe element 5, the inner diameter or Bore 10 can correspond to that of the pipe 2, is one of the outer diameter 6 of the tube 2 corresponding stepped bore 7 provided with the connection axis 18 vertical end face 8. In the latter is a circular ring form Groove 11 is provided, the outer diameter of which approximates the diameter of the bore 7, or the outer diameter 6 of the tube 2, and its inner diameter is larger than the bore of the pipe 2 or of the pipe element 5.
Beim Erhitzen der Enden der beiden Rohrleitungselemente 2 und 5 durch die eingeschoben Heizvorrichtung 1 werden die Aussendurchmesser 6 und der Umfang des Absatzes 4 des Rohres 2, sowie die Bohrung 7 des Rohrleitungselementes 5 auf Schmelztemperatur erhitzt, jedoch die beiden Stirnflächen*3 und 8 nicht, und an den Stellen 12, 13, 14 und 15 sammelt sich geschmolzener Werkstoff an. Nach dem Herausziehen der Heizvorrichtung 1 werden die beiden Teile 2 und 5 ineinander geschoben, wobei der geschmolzene Werkstoff bei 16 eine zusätzliche äussere Schweissnaht bildet und beim Absatz 4 in die Auskerbung oder Nute 11 eindringt und dadurch eine sichere Dichtung 7 entsteht. Da die beiden Stirnseiten 3 und 8 nicht geschmolzen sind, können sie bündig aneinander gestossen werden und sie bilden somit einen glatten Durchgang für das durch die Bohrungen 9 und lo der Rohrverbindung strömende Medium. When the ends of the two pipe elements 2 and 5 are heated the inserted heating device 1, the outer diameter 6 and the circumference of paragraph 4 of the pipe 2, as well as the bore 7 of the pipe element 5 Melting temperature heated, but the two end faces * 3 and 8 not, and on Molten material accumulates at points 12, 13, 14 and 15. After this Pulling out the heating device 1, the two parts 2 and 5 are pushed into one another, the molten material forming an additional outer weld seam at 16 and in paragraph 4 in the Notch or groove 11 penetrates and thereby a secure seal 7 is created. Because the two end faces 3 and 8 are not melted they can be butted together flush to form a smooth one Passage for the medium flowing through the bores 9 and lo of the pipe connection.
Die Fig. 2 zeigt als weiteres Aüsführungsbeispiel einen Längsschnitt
durch eine Verbindung, bei der das linksseitige Rohrleitungselement 19 aus einem
zylindrischen Rohr mit der glatten Stirnfläche 3, jedoch ohne Absatz besteht. Beim
Zusammenschieben der beiden an den geeigneten Stellen erhitzten Rohrleitungselemente
5 und 19 bildet sich wiederum bei 16 eine zusätzliche äussere Schweissnaht und der
am Aussendurchmesser 7 geschmolzene Werkstoff dringt in die Nute 11 ein und bil-
