Befestigung von auswechselbaren Sitzringen in der Sitzöffnung von Absperrvorriefatungen. Patentiert im Deutschen Reiche vom 4. Januar 1924 ab. Fastening of replaceable seat rings in the seat opening of shut-off devices. Patented in the German Empire on January 4, 1924.

Gegenstand der Erfindung ist eine Befestigung von auswechselbaren Sitzringen in der Sitzöffnung von Absperrvorrichtungen, wie Ventilen, Schiebern o. dgl.
Das Wesen der Erfindung liegt in einem in den Sitzring von innen eingepreßten, außen kegeligen Hohlring. Infolge der hierdurch erzielten Verspannung ist der Druck des Durchgangsmittels ohne jeden Einfluß darauf ίο und kann daher beliebige Höhe haben. Den- i noch kann der Preßring nach dem Innern det Absperrvorrichtung ausgestoßen werden, wenn die Verbindung gelöst werden soll.The subject of the invention is an attachment of replaceable seat rings in the seat opening of shut-off devices, such as valves, slides or the like.
The essence of the invention lies in a hollow ring which is pressed into the seat ring from the inside and is tapered on the outside. As a result of the tension achieved in this way, the pressure of the passage means has no influence on it and can therefore have any height. Nevertheless, the press ring can be ejected towards the interior of the shut-off device if the connection is to be released.

Eine Ausfuhrungsform des Erfindungsgegenstandes ist in der Zeichnung beispielsweise dargestellt.One embodiment of the subject matter of the invention is shown in the drawing, for example shown.

Der Sitzring h mit Flansch b1 und zylindrischem oder sich verjüngendem Mantel bs wird in den Durchgang ei eines Gehäuses α eingebracht, so daß sich die Flanschunterseite aufThe seat ring h with flange b 1 and cylindrical or tapering jacket b s is introduced into the passage ei of a housing α, so that the flange underside on

die Stirnfläche α1 der Durchgangsbegrenzung α aufsetzt. In den Mantelteil b2 wird von der entgegengesetzten Seite ein Ring c mit kegeliger Außenfläche c1 eingeführt, wodurch der Mantel des bereits mit seiner Schulter b1 aufliegenden Sitzringes b gegen die Begrenzung α des Durchgangs d gepreßt und damit die Abdichtung herbeigeführt wird. Vorteilhafter erfolgt das Einbringen des Sitzringes in der in Abb. 2 und 3 dargestellten Weise. Hierbei wird der Klemm- oder Spannring c, c1 zunächst außerhalb des Gehäuses in den Sitzring b, b1, b2 teilweise eingetrieben. Dann erfolgt deren gemeinsames Einsetzen in den Durchgang d eines Gehäuses a, so daß sich der Sitzring mit seiner Schulter b1 auf die Stirnfläche α1 aufsetzt und hierauf wird unter Niederhalten des Sitzringes der Klemmring c, c1 mit Gewalt vollends in den ersteren eingetrieben (Abb. 3). Bei etwa erforderlichem Ausbau des Sitzringes b wird zunächst der Spannring c nach unten ausgestoßen und dann der obere Ring herausgenommen.the end face α 1 of the passage limit α touches down. A ring c with a tapered outer surface c 1 is inserted into the shell part b 2 from the opposite side, whereby the shell of the seat ring b already resting with its shoulder b 1 is pressed against the boundary α of the passage d and thus the seal is brought about. It is more advantageous to insert the seat ring in the manner shown in FIGS. 2 and 3. Here, the clamping or tensioning ring c, c 1 is first partially driven into the seat ring b, b 1 , b 2 outside the housing. Then they are jointly inserted into the passage d of a housing a, so that the seat ring rests with its shoulder b 1 on the end face α 1 and then, while holding down the seat ring, the clamping ring c, c 1 is forcibly driven completely into the former ( Fig. 3). If it is necessary to remove the seat ring b , the clamping ring c is first ejected downwards and then the upper ring is removed.

Ist einmal der Sitz α eines Absperrmittels zur Aufnahme des Sitzringes in der beschriebenen Art vorbereitet, so kann ein Austausch seiner Teile einfach und rasch an Ort und Stelle vorgenommen werden, ohne daß hierzu das die Sitzringbefestigung tragende Gehäuse des Absperrmittels aus den damit ausgerüsteten Maschinen und Leitungen entfernt werden müßte. Aus diesem Grunde kann die neue Sitzringbefestigung auch bei bereits in Betrieb befindlichen Absperrmitteln, und zwar selbst in deren Einbaustellung nachträglich Verwendung finden.Once the seat α of a shut-off means has been prepared for receiving the seat ring in the manner described, its parts can be exchanged quickly and easily on the spot without having to remove the shut-off means housing that supports the seat ring from the machines and lines equipped with it would have to be removed. For this reason, the new seat ring fastening can also be used retrospectively with shut-off devices that are already in operation, even in their installed position.
