Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die vorliegende Flanschenverbindung ist für schmiedeiserne Röhren mit durch Umbiegung gebildeten Flanschen bestimmt und besteht aus einem Klemmringpaar, mittels dessen die Flanschen zusammengedrückt werden. Die Verbindung ist dadurch gekennzeichnet, dals die Klemmringe am äufseren Rande der einander zugekehrten Seiten mit je einer vorspringenden Rippe versehen sind, mit denen die Ringe beim Anziehen der Schrauben zunächst in gegenseitige Berührung treten. Sobald dies der Fall ist und die Schrauben darauf weiter angezogen werden, tritt unter geringem Durchdrücken der Klemmringe in erhöhtem Mafse eine gegenseitige Annäherung der inneren Ränder der Klemmringe ein, wobei die letzteren — im Querschnitt betrachtet — nach Art einarmiger Hebel wirken, indem gleichsam ein gegenseitiges Einwärtsschwenken der inneren Ränder der Ringe um den am äufseren Rande von den Rippen gebildeten Stützpunkt stattfindet. The present flange connection is for wrought iron pipes with by bending formed flanges and consists of a pair of clamping rings, by means of which the Flanges are compressed. The connection is characterized as the clamping rings on the outer edge of the facing sides with one protruding each Ribs are provided with which the rings initially come into mutual contact when the screws are tightened. As soon If this is the case and the screws on it are further tightened, minor occurs Pressing through the clamping rings to an increased extent brings the inner rings closer together Edges of the clamping rings, the latter - viewed in cross section - after Kind of one-armed levers work by, as it were, a mutual inward pivoting of the inner Edges of the rings takes place around the support point formed by the ribs on the outer edge.

Durch diese hebelartige Wirkung der Klemmringe wird ein äufserst kräftiges Aneinanderpressen der Flanschen herbeigeführt, zwischen welchen sich ein geeignetes Dichtungsmaterial befindet.This lever-like effect of the clamping rings results in an extremely strong pressing against one another the flanges brought about, between which a suitable sealing material is located.

Fig. ι der beiliegenden Zeichnung veranschaulicht die Flanschenverbindung vor der gegenseitigen Berührung der Klemmringe^ Fig. 2 nach deren Berührung und weiter fortgesetztem Anziehen der Schrauben.Fig. Ι the accompanying drawing illustrates the flange connection before the clamping rings touch each other ^ Fig. 2 after touching them and continuing to tighten the screws.

Die zu verbindenden schmiedeisernen Röhren α sind durch Umbiegung mit Flanschen b versehen. Zwischen den Flanschen liegt das Dichtungsmittel c. The wrought iron tubes α to be connected are provided with flanges b by bending them. The sealant c is located between the flanges.

Für jede Flanschenverbindung wird auf jedes Rohr ein Klemmring d geschoben, der am äufseren Rande an der dem zugehörigen Rohrflansch b zugekehrten Seite mit einer vorspringenden, ringsum laufenden Rippe e versehen ist. Statt der ringsum laufenden Rippe könnten auch einzelne Zähne angeordnet sein.For each flange connection, a clamping ring d is pushed onto each pipe, which is provided on the outer edge on the side facing the associated pipe flange b with a projecting rib e running all around. Instead of the rib running all around, individual teeth could also be arranged.

Es kommen unter zunächst gelindem Zusammendrücken des Dichtungsmittels die vorspringenden Rippen e oder die dieselben ersetzenden Zähne der Klemmringe mit einander in Berührung, worauf bei weiterem Anziehen der Schrauben unter geringem Durchdrücken der Klemmringe ein zufolge der nunmehr gleichsam hebelartigen Wirkung der Klemmringe äufserst kräftiges Aneinanderdrücken der Rohrflanschen b eintritt. The protruding ribs e or the teeth of the clamping rings that replace them come into contact with one another, initially by gently compressing the sealant , whereupon the pipe flanges b are pressed against each other very vigorously as the screws are tightened while the clamping rings are pushed through slightly, as a result of the now almost lever-like effect of the clamping rings entry.

Bei Anwendung von Zähnen statt der Rippen e können erstere auch versetzt angeordnet werden, nur müssen die Zähne dann die erforderliche Höhe haben, um rechtzeitig mit dem gegenüberliegenden Klemmring in Berührung zu treten.If teeth are used instead of the ribs e , the former can also be arranged offset, only the teeth must then have the required height in order to come into contact with the opposite clamping ring in good time.
