Schutzvorrichtung für Rohranschlüsse gegen Rost.Protection device for pipe connections against rust.
Ein ständiger Übelstand bei Anschlüssen von. eisernen Rohren an irgendwelche Armaturen oder andere Rohre besteht darin, daß das Rohr an dieser Anschlußstelle, nachdem das Gewinde angeschnitten worden ist, nicht wieder genügend gegen Rost geschützt werden, kann, da durch das Einspannen des Rohres durch Anschneiden des. Gewindes durch das Eindrehen des Rohres der Zink- oder Asphaltüberzug des Rohres an dieser Stelle leidet und nicht oder nur sehr unvollkommen an dem angeschraubten Rohr wieder angebracht werden kann.A constant drawback when connecting. iron pipes to some fittings or other pipes is that the pipe at this connection point after the thread has been cut, not can be adequately protected against rust again, as by clamping the Pipe by cutting the thread by screwing in the pipe of the zinc or asphalt coating of the pipe suffers at this point and not at all or only very imperfectly can be reattached to the screwed-on tube.
Diesen Übelstand zu vermeiden, dient die vorliegende Erfindung, welche in einer Schutzhülse von einer der zu schützenden Stelle entsprechenden Länge besteht, die über die genannte Stelle des Rohres geschoben und bajonettverschlußartig mit dem Anschlußkörper verbunden ist. Die durch die Bearbeitung blank gewordene Stelle wird dadurch mit einem dicken Überzug von dem genannten Stoff versehen und so in jedem Falle vor Verrosten geschützt, auch wenn das Rohr in die Erde eingegraben wird.The present invention, which is provided in a protective sleeve, serves to avoid this inconvenience of a length corresponding to the point to be protected, which extends over the called point of the pipe pushed and bayonet-like with the connecting body connected is. The area that has become blank as a result of the processing will be included provided with a thick coating of the said substance and thus protected against rusting in any case, even if the pipe is in the earth is buried.
Eine Verwendungsform dieser Schutzhülse ist in der beiliegenden Zeichnung dargestellt, und zwar zeigen die Fig. 1 und 2 in Längsschnitt und Vorderansicht den durch eine derartige Schutzhülse geschützten Anschluß eines Rohres an eine sogenannte Anbohrschelle für Wasserleitungsrohre.One form of use of this protective sleeve is shown in the accompanying drawing, namely show FIGS. 1 and 2 in longitudinal section and front view through a such protective sleeve protected connection of a pipe to a so-called tapping clamp for water pipes.
In den Fig. 1 und 2 ist α das Hauptrohr, an welchem mittels der Schelle b das Kniestück c in bekannter Weise befestigt ist. In dieses Kniestück c wird das beispielsweise ■ als Hausleitung dienende Rohr d bei e eingeschraubt. In FIGS. 1 and 2, α is the main pipe to which the elbow c is attached in a known manner by means of the clamp b. The pipe d , which is used as a house line, for example, is screwed into this elbow c at e.
Auf dem Rphr d sitzt eine Schutzhülse f aus beliebigem Material, beispielsweise aus Gußeisen, welche bei g das Rohr d ziemlich dicht umfaßt, während sie sonst zwischen Rohr und ihrer Wandung einen breiten Ringraum frei läßt, der durch eine Öffnung h nach außen in Verbindung steht. Die Hülse besitzt einen halbkreisförmigen Flansch i an ihrem vorderen Ende, der sich in eine entsprechende ■ Aussparung j des Winkelstücks c legt. Dieser Flansch i sowohl als auch die Aussparung / können zweckmäßig schraubengangartig mit geringem Anzug ineinandergreifen, um durch Drehung der Hülse ein festes Anpressen derselben an das Winkelstück bei k bewirken zu können.On the pipe d sits a protective sleeve f made of any material, for example cast iron, which surrounds the pipe d fairly tightly at g , while otherwise it leaves a wide annular space free between the pipe and its wall, which is connected to the outside through an opening h . The sleeve has a semicircular flange i at its front end, which lies in a corresponding recess j of the angle piece c. This flange i as well as the recess / can expediently mesh with one another in a helical manner with a slight tightening in order to be able to effect a firm pressing of the same against the elbow at k by rotating the sleeve.
Nachdem die Hülse f über das Rohr g gestreift ist, wird das Rohr bei e in das Winkelstück c der Anbohrschelle eingeschraubt und dann der Flansch i in die Aussparung / eingelegt und angezogen. Durch die Öffnung h gießt man alsdann irgendwelche Isoliermasse, beispielsweise Asphalt,. Zement o. dgl., in das Innere der Hülse, eventuell nach Erwärmung der Hülse und des darunter liegenden Rohres mittels einer Lötlampe o. dgl. Dadurch wird diese Anschlußstelle mit einer dicken Isolierschicht umgeben, so daß ein Rosten nicht möglich ist.After the sleeve f has slipped over the pipe g , the pipe is screwed into the angle piece c of the tapping clamp at e and then the flange i is inserted into the recess / and tightened. Any insulating compound, for example asphalt, is then poured through the opening h. Cement or the like into the interior of the sleeve, possibly after heating the sleeve and the pipe underneath by means of a blowtorch or the like. As a result, this connection point is surrounded with a thick insulating layer so that rusting is not possible.
An Stelle des halbkreisförmigen Flansches i Instead of the semicircular flange i
Claims (1)
ίο Die Schutzvorrichtung kann natürlich für alle möglichen Arten von Armaturen und Rohrstücken Verwendung finden und selbstverständlich auch für andere Rohre als Wasserrohre, beispielsweise für Dampf, Gas usw.Of course, you can also attach only individual lugs to the sleeve, or you can bring about the firm pressing of the sleeve in the body of the pipe clamp in some other way, for example by wedges or in some other way. The sleeve can possibly also be made in two parts so that it can still be placed over the connection point when the pipe is screwed in.
ίο The protective device can of course be used for all kinds of fittings and pipe sections and of course also for pipes other than water pipes, for example for steam, gas, etc.
