Description
Einrichtung zum Prüfen der Dichtheit von Rohrverbindungen. Die Erfindung betrifft eine Einrichtung zum Prüfen der Dichtheit von Rohrverbin dungen und besteht darin, dass mindestens eine ringförmige Packung von einer beweg lichen Anpressvorrichtung derart an die zu prüfende Stelle angepresst wird, dass an dieser ein geschlossener Raum gebildet wird, in den ein Druckmittel eingeführt werden kann. Die Packung kann vom Rohrinnern oder auch von aussen her an die Verbindungsstelle ange- presst werden.
Sie lässt sich auch derart ring förmig ausbilden, dass ein über die ganze Ausdehnung der Verbindungsstelle sich er streckender Ringraum zum Einführen der Druckflüssigkeit gebildet wird. .
In der Zeichnung sind drei Ausführungs beispiele des Erfindungsgegenstandes zur. Darstellung gebracht.
Fig. 1 ist eine im Innern der Rohrleitung, itnd Fig. 4 eine ausserhalb der Rohrleitung zu verwendende Einrichtung zum stückweisen Prüfen der Dichtheit von Rohrverbindungs- nähten; Fig. 2 ist ein Teil der Fig. 1 in grösserem Massstab gezeichnet, Fig. 3 ein Schnitt nach der Linie III-I11 der Fig. 2, und Fg. 5 ein in grösserem Massstab gezeich neter Teil der Fig. 4.
In Fig. 6 ist eine ringförmige Einrichtun-; gezeigt, vermittelst welcher eine Rohrverb1n- dungsnaht in ihrer ganzen Ausdehnung auf einmal geprüft werden kann.

dass über der Verbindungsnaht. fein geschlocz- sener Raum g entsteht, in welchem vermit- 1-elst einer nicht weiter gezeichneten Vorrich tung, durch die Bohrung h Druckflüssigkeit eingeführt werden kann, zum Zweck. rnit Hilfe der Druckflüssigkeit feststellen zu kön nen, ob der unter Druck gesetzte Teil der Verbindungsnaht dicht ist oder nicht.
Bei dem Ausführungsbeispiel nach den Fig. 1 bis 3, das zum Arbeiten im Rohr- innern ausgebildet ist, sind zwei derartige Einrichtungen durch Stangen<I>i</I> und<I>7c.</I> von denen die eine mit einem Linksgewinde und die andere mit einem Rechtsgewinde in eine INTutter 1 eingreift, derart miteinander kom biniert, dass sie durch das Anziehen der Mut ter an zwei einander gegenüberliegende Stel len der Rohrverbindung angepresst werden.
Nach erfolgter Prüfung dieser Stellen kann die ganze Einrichtung durch Lösen der Nutter an andere Stellen verschoben werden.
Bei dem zum Arbeiten ausserhalb des Rohres bestimmten Ausführungsbeispiel nach den Fig. 4 und 5 wird das Anpressen der Einrichtung durch eine Schraube in bewerk stelligt, die in einem Joch n eines um die Rohrleitung herumgeschlungenen Bandes o angeordnet ist.
Bei dem Ausführungsbeispiel nach Fig. 6 ist sowohl die Packung a, wie auch der An- presskörper b als ein parallel zu der Rohrnah t f laufender Ring und so ausgebildet, dass ein über die ganze Ausdehnung der Rohrnaht f sich erstreckender ringförmiger Druckraum entsteht. Die Packung ist mit Stulpen p ver sehen, die vom Druckmittel selbst dichtend an die Rohrenden angepresst werden.
Device for checking the tightness of pipe connections. The invention relates to a device for testing the tightness of pipe connections and consists in that at least one ring-shaped packing is pressed against the point to be tested by a movable union pressure device in such a way that a closed space is formed there, into which a pressure medium is introduced can. The packing can be pressed against the connection point from the inside of the pipe or from the outside.
It can also be designed to be ring-shaped in such a way that an annular space for introducing the pressure fluid is formed which extends over the entire extent of the connection point. .
In the drawing are three execution examples of the subject invention. Representation brought.
1 is an inside the pipeline, and FIG. 4 shows a device to be used outside the pipeline for testing the tightness of pipe connection seams piece by piece; FIG. 2 is a part of FIG. 1 drawn on a larger scale, FIG. 3 is a section along the line III-I11 in FIG. 2, and FIG. 5 is a part of FIG. 4 drawn on a larger scale.
In Fig. 6 is an annular device; shown, by means of which a pipe connection seam can be tested in its entire extent at once.
<I> a </I> is the ring-shaped packing and li is the device by means of which the packing is pressed against the connection points of the connected pipe ends <I> d </I> and <I> e </I> becomes.
that over the joint. Finely closed space g is created in which, by means of a device not shown any further, hydraulic fluid can be introduced through the bore h for the purpose. To be able to determine with the help of the hydraulic fluid whether the pressurized part of the connection seam is tight or not.
In the exemplary embodiment according to FIGS. 1 to 3, which is designed to work inside the pipe, two such devices are provided with rods <I> i </I> and <I> 7c. </I>, one of which with one left-hand thread and the other with a right-hand thread engages in an INTutter 1, combined with one another in such a way that they are pressed against two opposite stel sources of the pipe connection by tightening the nut.
Once these points have been checked, the entire facility can be moved to other points by loosening the nuts.
In the embodiment according to FIGS. 4 and 5, intended for working outside the pipe, the device is pressed on by a screw which is arranged in a yoke n of a band o looped around the pipeline.
In the exemplary embodiment according to FIG. 6, both the packing a and the pressing body b are designed as a ring running parallel to the pipe seam t f and in such a way that an annular pressure space is created extending over the entire extent of the pipe seam f. The pack is provided with cuffs p, which are pressed tightly against the pipe ends by the pressure medium itself.
