Description

Elektrisch isolierte und dichte Wandeinführung für Heizölbehälter Die Erfindung betrifft eine elektrisch isolierte und dichte Wandeinführung für mindestens zwei Ölleitungen, die in einen Heizölbehälter einsetzbar ist.Electrically insulated and sealed wall entry for heating oil tanks The invention relates to an electrically insulated and tight wall entry for at least two oil lines that can be inserted into a heating oil tank.

Zum Anschluß eines Heizölbehälters an einen Ölbrenner werden mindestens eine Saug- oder Vorlaufleitung und eine Rücklaufleitung benötigt. Bezüglich dieser Leitungen wird meist eine elektrische Isolierung gegen den Heizölbehälter verlangt. Außerdem sollen die Rohre in der Wandeinführung einen festen Sitz gegenüber etwaigen äußeren Kräften aufweisen.To connect a heating oil tank to an oil burner, at least a suction or supply line and a return line are required. Regarding this Lines are usually required to be electrically insulated from the fuel oil tank. In addition, the pipes should be firmly seated in the wall entry have external forces.

Bei einem bekannten explosionsgesicherten Kabelanschluß ist eine metallische Einschraubbuchse bekanntgeworden, deren eingegossene Zementfüllung isolierte, durchgeführte Kabel festhält. Dieses Prinzip auf Wandeinführungen der vorbeschriebenen Art zu übertragen ist nicht möglich, weil ein Festsitz nicht gegeben ist und das Fließen etwaiger Kriechströme durch die metallische Buchse begünstigt ist.In a known explosion-proof cable connection is a metallic one Screw-in socket became known, whose cement filling insulated, carried out Holds the cable in place. This principle applies to wall entries of the type described above Transfer is not possible because there is no tight fit and there is no flow any leakage currents through the metallic socket is favored.

Aufgabe der Erfindung ist es, eine Wandeinführung zu schaffen, die, mit den durchgeführten Rohrleitungen als eine Baueinheit vorgefertigt, nur in eine Einstecköffnung des Behälters eingesetzt und befestigt zu werden braucht. Außerdem soll die Wandeinführung eine einwandfreie elektrische Isolation gewährleisten.The object of the invention is to create a wall entry that, prefabricated with the pipelines carried out as a structural unit, only in one Insertion opening of the container needs to be inserted and fastened. aside from that the wall entry should ensure perfect electrical insulation.

Gelöst wird die gestellte Aufgabe erfindungsgemäß dadurch, daß die Leitungen von einem gemeinsamen, sie allseits umfassenden, kreiszylindrischen Isolationskörper einstückig umgossen, umpreßt oder umspritzt sind, der mittels eines angeformten Flanschbundes und einer überwurfmutter in einem handelsüblichen Einschraubdoppelnippel dichtend befestigt ist, und daß die Leitungen durch eine Metallbrücke miteinander verbunden sind.The object is achieved according to the invention in that the Lines from a common, circular-cylindrical insulation body encompassing them on all sides encapsulated in one piece, molded or molded, by means of an integrally formed Flange collar and a union nut in a standard screw-in double nipple is tightly attached, and that the lines are connected by a metal bridge are connected.

Die Metallbrücke besteht dabei aus einem Metallstück, das Durchtrittsöffnungen oder nach außen offene Anlageflächen für die Rohrleitungen aufweist.The metal bridge consists of a piece of metal, the passage openings or has outwardly open contact surfaces for the pipelines.

Die erfindungsgemäße Wandeinführung ist einfach herzustellen und gewährleistet eine sichere Abdichtung und elektrische Isolierung der durchgeführten Rohrleitungen. Durch die Metallbrücke wird außerdem eine gute Festigkeit gegenüber an den Rohren angreifenden Kräften erreicht.The wall lead-in according to the invention is easy to manufacture and guaranteed reliable sealing and electrical insulation of the pipelines that are passed through. The metal bridge also provides good strength on the pipes attacking forces reached.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigt F i g. 1 einen Ausschnitt aus einem Heizölbehälter mit einer erfindungsgemäßen Wandeinführung und F i g. 2 eine Ansicht der Wandeinführung nach F i g. 1 in Pfeilrichtung.An embodiment of the invention is shown in the drawing and is described in more detail below. It shows F i g. 1 a section a heating oil tank with a wall inlet according to the invention and FIG. 2 one View of the wall entry according to FIG. 1 in the direction of the arrow.

In F i g. 1 ist ein Ausschnitt aus einer Behälterwand 1 eines Heizölbehälters mit einer Öffnung 3 dargestellt, auf welcher ein Flanschring 5 angeschweißt ist. Dieser Flanschring 5 weist auf seiner Außenseite eine Nut 7 zum Einlegen eines Dichtungsringes 27 auf und ist mit einem Innengewinde 9 zum Einschrauben eines handelsüblichen Einschraubdoppelnippels 23 versehen.In Fig. 1 is a section from a container wall 1 of a fuel oil container shown with an opening 3 on which a flange ring 5 is welded. This flange ring 5 has a groove 7 on its outside for inserting a sealing ring 27 and has an internal thread 9 for screwing in a commercially available screw-in double nipple 23 provided.

Eine Vorlaufleitung 11, durch die das Heizöl aus dem Behälter angesaugt wird, und eine Rücklaufleitung 13, durch die das überschüssig geförderte Öl in den Behälter zurückfließt, sind miteinander über eine Metallbrücke 15 verbunden. Neben den beiden Leitungen 11 und 13 befindet sich, wie aus F i g. 2 ersichtlich, ein Flüssigkeitsmeßrohr 17.A feed line 11 through which the fuel oil is sucked out of the container is, and a return line 13 through which the excess oil pumped into the Containers flowing back are connected to one another via a metal bridge 15. Next to the two lines 11 and 13 is, as shown in FIG. 2 can be seen Liquid measuring tube 17.

Die beiden Leitungen 11 und 13 mit der Metallbrücke 15 und dem Flüssigkeitsmeßrohr 17 sind in einen Isolationskörper 19 eingegossen oder eingepreßt. Dieser Isolationskörper 19 ist zylinderförmig und weist einen Flanschbund 21 auf.The two lines 11 and 13 with the metal bridge 15 and the liquid measuring tube 17 are cast or pressed into an insulating body 19. This insulation body 19 is cylindrical and has a flange collar 21.

Der Isolationskörper 19 mit der Vorlauf- und der Rücklaufleitung 11 bzw. 13 sowie dem Flüssigkeitsmeßrohr 17 wird in den Einschraubdoppelnippel 23 eingeschoben, bis der Flanschbund 21 auf dem Dichtungsring 29 aufliegt, und hierauf das ganze Gebilde mittels des unteren Nippelteiles des Einschraubdoppelnippels 23 in den Flanschring 5 eingeschraubt, bis der Flanschring 5 des Einschraubdoppelnippels 23 auf dem Dichtungsring 27 dichtend aufliegt.The insulation body 19 with the flow line and the return line 11 or 13 and the liquid measuring tube 17 is pushed into the screw-in double nipple 23, until the flange 21 rests on the sealing ring 29, and then the whole Formation by means of the lower nipple part of the screw-in double nipple 23 in the flange ring 5 screwed in until the flange ring 5 of the screw-in double nipple 23 on the sealing ring 27 rests sealingly.

Hierauf wird eine überwurfmutter 25 über den Isolationskörper 19 geschoben und dieser mit seinem Flanschbund 21 festgespannt. Für den Isolationskörper kann irgendein gieß-oder preßfähiges Isolationsmaterial, insbesondere ein Epoxyd-Kunstharz verwendet werden.A union nut 25 is then pushed over the insulation body 19 and this clamped with its flange collar 21. For the insulation body Any insulation material that can be cast or pressed can be used, in particular an epoxy synthetic resin be used.
