KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Durch die schweizerische Patentschrift 5375 (Fig". 6) ist es bekannt geworden, einen Dichtungsring herzustellen, der dadurch gekennzeichnet ist, daß ineinander liegende Dichtungsscheiben durch einen Metallring von U-förmigem Querschnitt zusammengehalten werden. Hiervon unterscheidet sich der Dichtungsring der vorliegenden Erfindung dadurch, daß übereinander liegende kreisrunde Dichtungs-Scheiben durch einen Metallring ' von S-förmigem Querschnitt zusammengehalten werden. Dadurch soll eine äußerst einfache, billige und möglichst dauernde Dichtung erreicht werden, da ein Ausblasen des Dichtungsmittels ausgeschlossen erscheint, ganz gleichgültig, von welcher Seite der Druck kommt.By Swiss patent 5375 (Fig ". 6) it has become known to produce a sealing ring, which is characterized is that nested sealing washers through a metal ring of U-shaped Cross-section are held together. The sealing ring differs from this of the present invention in that superimposed circular sealing washers are held together by a metal ring 'of S-shaped cross-section. This is an extremely simple, cheap and permanent seal can be achieved, as a blowing out of the sealant seems impossible, regardless of which side the pressure comes from.
Auf der Zeichnung zeigt:
Fig. I einen Dichtungsring im Schnitt,
Fig. 2 denselben in Draufsicht,The drawing shows:
Fig. I a sealing ring in section,
Fig. 2 the same in plan view,
Fig. 3 den groß herausgezeichneten Querschnitt des Dichtungsringes.3 shows the large cross-section of the sealing ring.
Der den Gegenstand der Erfindung bildende Dichtungsring besteht aus einem ein einziges Stück bildenden Ring α von S-förmigem Querschnitt, der gleichzeitig sowohl die Dichtungsscheibe b, als auch die Dichtungsscheibe c aufnimmt. Der Ring α von S-förmigem Querschnitt übergreift zweckentsprechend die Scheibe c etwas mehr, da die Flanschen oft ungenau bearbeitet sind oder, wie es öfters vorkommt, die Flanschen nicht gleichmäßig angezogen werden.The sealing ring forming the subject of the invention consists of a single piece forming ring α of S-shaped cross-section, which at the same time receives both the sealing washer b and the sealing washer c. The ring α of S-shaped cross-section appropriately overlaps the disk c somewhat more, since the flanges are often imprecisely machined or, as is often the case, the flanges are not tightened evenly.
Der Dichtungsring besteht aus zwei Teilen, und zwar:The sealing ring consists of two parts, namely:
1. aus den zur Dichtung der Flanschenverbindung verwendeten Dichtungsscheiben,1. from the sealing washers used to seal the flange connection,
2. aus dem zum Zusammenhalten dieser Scheiben erforderlichen Metallring.2. from the metal ring required to hold these discs together.
Wie aus beiliegender Zeichnung ersichtlich, ist der Dichtungsring so ausgeführt, daß dazwischen zwei übereinander liegenden Dichtungsscheiben eingelegte Metallring an der oberen äußeren und an der unteren inneren Kante oder umgekehrt nach verschiedenen Richtungen S-förmig umgebogen ist und dadurch die beiden Dichtungsscheiben zusammenhält. As can be seen from the accompanying drawing, the sealing ring is designed so that between two sealing washers placed one above the other, inserted metal ring on the upper outer and lower inner Edge or vice versa is bent in S-shape in different directions and thereby holds the two sealing washers together.
Es wird hierdurch, und das ist das Neue an dem Ringe, erreicht, daß die übereinander liegenden Dichtungsscheiben durch die Umklammerung durch den S-förmigen Metallring gegen das Herausschleudern bei hohem Innendruck gesichert werden.In this way, and this is what is new about the ring, it is achieved that they are superimposed on one another lying sealing washers through the clasping of the S-shaped metal ring be secured against being thrown out at high internal pressure.
