Description
IDig. -Hrfiri Jung ..betrifft eine Vorrichtung zum Verschließen: von Rohren, insbesondere von An, schlußnippeln oder -stutzen an Behältern, die einer Druckprobe unterzogen werden- sollen. -Vielfach, insbesondere dann; wenn mit Anoder. Nippeln: versehene Behälter '" einer `Druckprobe unterzögen werden sollen, ist--es' @-rlötwendig, die Anschlüsse des Behälters abzudichten. Bisher wurden in solchen Fällen entweder Stopfen in die Verschlüsse eingebracht, was insbesondere bei hohen Abpreßdrücken unzureichend ist, oder es wurden in jeden Anschluß Blechscheiben entsprechenden Durchmessers eingeschweißt. Letztere Art ist zwar zuverlässig, bedingt aber einen überaus großen Arbeitsaufwand für das Anschweißen und vor allem nach dem Abdruckvorgang für das - Entferhen der Blechscheiben durch Aufbohren und Fräsen einer neuen Schweißkante. Beim Entfernen der eingeschweißten Blechscheiben besteht darüber hinaus die Gefahr, däß nicht alle Bohr- und Frässpäne aus den oft nicht oder nur sehr schlecht zugänglichen Behältern entfernt werden und sich --nachher- -im Betrieb in Regelorganen, Ventilen u. dgl. ablagern und dadurch Störungen verursachen. Durch die Erfindung werden diese Nachteile vermieden und eine Vorrichtung geschaffen, die es ermöglicht, einfach und schnell Rohre od. dgl. zu verschließen.IDig. -Hrfiri Jung .. concerns a device for closing: von Pipes, in particular on, connection nipples or nozzles on containers that one Pressure test should be subjected. -Multiple, especially then; if with Anoder. Nipples: provided containers '"are to be subjected to a` pressure test, is - it' @ -rlötwendig to seal the connections of the container. So far have been in such Cases either stoppers are inserted into the closures, which is particularly the case with high Pressing off is insufficient, or sheet metal washers have been used in each connection Welded in diameter. The latter type is reliable, but requires one extremely large amount of work for the welding and especially after the impression process for - removing the sheet metal disks by drilling and milling a new welding edge. When removing the welded sheet metal disks, there is also the risk of That not all drilling and milling chips come from the often inaccessible or very poorly accessible Containers are removed and - afterwards - in operation in control devices, valves and the like deposit and thereby cause malfunctions. With the invention, these Avoided disadvantages and created a device that makes it easy and to close tubes or the like quickly.
Die Erfindung besteht darin, daß eine in das Rohr eingebrachte mehrfach geteilte- Büchse mit konischer Innenbohrung durch den konischen Kopf einer-Spannschraube fest gegen die- innere Rohr= wand gedrückt wird, während gleichzeitig durch das Spannen der Spannschraube eine mit in das Rohr eingeführte Manschette aus Gummi od. dgl._ so. zusammengedrückt wird, daß sie den Rohrquerschnitt abdichtet. Es ist also durch Lösen bzw: Anziehen nur einer Spannschraube sowohl die Klemm- als auch die-Dichtvörrichtung zu betätigen, wobei der Rohrstutzen weder ;beschädigt wird noch Nacharbeiten an demselben erforderlich sind. Die Anwendung der Vorrichtung ist auch bei engster Rohrteilung; z. B. an Sammelkammern für Dampfk esselanlagen, ohne Schwierigkeit möglich.The invention consists in that one introduced into the pipe several times Split bushing with a conical inner bore through the conical head of a clamping screw is pressed firmly against the inner pipe wall, while at the same time through the Tension the tensioning screw with a rubber sleeve inserted into the pipe or the like_ so. is compressed so that it seals the pipe cross-section. It is so by loosening or: tightening only one clamping screw both the clamping and to operate the sealing device, whereby the pipe socket is neither damaged rework is still required on the same. The application of the device is also with the narrowest pipe spacing; z. B. on collecting chambers for steam boiler systems, possible without difficulty.
Um das Herausnehmen der Vorrichtung nach dem Abdruckvorgang zu erleichtern:, ist gemäß der Erfindung der .konische Kopf der Spannschraube mit Flössen. versehen, die in den Teilungsspalten der mehrteiligen Büchse während des Spanners liegen und beim Herausnehmen durch das Zurückdrücken und Drehen der Spannschraube unter die Büchsenteile fassen, so daß diese leicht aus dem Rohrende herauszunehmen: sind.To make it easier to remove the device after the impression process :, is according to the invention the .konical head of the clamping screw with rafts. Mistake, which lie in the division columns of the multi-part sleeve during the tensioner and when removing by pushing back and turning the clamping screw under the Take hold of the bushing parts so that they can be easily removed from the end of the pipe:.
In der Zeichnung ist in einem Ausführungsbeispiel die. erfindungsgemäße Vorrichtung im senkrechten ängsschnitt dargestellt.In the drawing is in one embodiment. according to the invention Device shown in vertical longitudinal section.
Die Spannschraube i ist mit einem konischen Kopf 2 ausgerüstet, welcher einen mehrteiligen Ring 3. mit konischer Innenfläche und aufgerauhter Außenfläche gegen die Innenwand des Rohrnippels 4 preßt. - Das Abdichten erfolgt durch eine Gummimanschette 5,, die beim Anziehen der Mutter b mittels der lose auf dem Schaft gleitenden Büchsen 7 und $. zusammengedrückt wird, so daß sie sich sowohl gegen die Rohrwand als auch gegen den Schraubenschaft preßt. Der konische Kopf 2 der Spannschraube i ist mit Flossen 9 ausgerüstet, die in den Teilungsspalten io der Büchse 3 liegen und beirr Herausnehmen der Vorrichtung unter die Büchsenteile gebracht werden, um das Herausnehmen zu erleichtern. Die Konusteile werden durch einen Federring- i i zusammengehalten.The clamping screw i is equipped with a conical head 2, which a multi-part ring 3. with a conical inner surface and a roughened outer surface presses against the inner wall of the pipe nipple 4. - Sealing is done by a Rubber sleeve 5 ,, which when tightening the nut b by means of the loose on the shaft sliding bushings 7 and $. is squeezed so that they are against both presses the pipe wall as well as against the screw shaft. The conical head 2 of the clamping screw i is equipped with fins 9 which are located in the dividing gaps io of the sleeve 3 and when removing the device are brought under the sleeve parts to to facilitate removal. The cone parts are i i held together.
