Abstract

The gas cut-off tap insulating piece (6) for domestic installations is prevented from twisting out of the tap by inserted or screwed-in components. Is is held in position through screwing into the tap through holes or slots in screw-in supports of the tap, into which corresponding pins (4) or balls are introduced which, by springs (5) or pin screws, (6) are pressed out of the insulating pie piece (3). The insulating piece can fit in a hatlike fashion over the key surfaces of the tap and is prevented from being twisted out by pin screws screwed on to the key surfaces.

Description

Anmelder:Applicant:

Herr Hartmut K 1 e i n Herr Joachim W e 5 p Herr Bernd W e s p Isolierstück für Hausinstallation zum nachträglichen Anbau an Absperrhähne für Gas Aus Sicherheitsgründen ist vom Gesetzgeber vorgeschrieben, daß die Gaszuführleitung und die Hausanschlußleitung durch ein zwischengeschaltetes Isolierstück elektrisch getrennt sein müssen. Mr. Hartmut K 1 e i n Mr. Joachim W e 5 p Mr. Bernd W e s p Isolierstück for house installation for retrofitting to shut-off cocks for gas For safety reasons is prescribed by law that the gas supply line and the house connection line must be electrically separated by an interposed insulating piece.

Es sind Lösungen bekannt geworden, bei denen mit in die Leitung eingebauten besonderen Isoliersftücken diese elektrische Trennung bewirkt wird. Dies erfordert jedoch einen gewissen Aufwand, und oftmals fehlt der Platz zum Einbau.Solutions have become known in which they are built into the line special insulating pieces this electrical separation is effected. This requires however, a certain amount of effort, and often there is not enough space for installation.

Neuerdings wurden Absperrhähne bekannt, die durch entsprechende kor.-struktive Gestaltung selbst mit einer solchen Isolierstrecke ausgerostet sind, so daß damit die elektrische Abtrennung gegeben ist.Shut-off cocks have recently become known, which have the corresponding cor.-structural Design even with such an insulating section are rusted, so that with it the electrical separation is given.

Die vorliegende Erfindung hat nun zum Ziel, bestehende Anlagen durch nachträglichen Anbau eines Isolierstückes an den vorhandenen Absperrhahn entsprechend den Vorschriften abzusichern. Auch bietet sich mit dieser Lösung die Möglichkeit, in Serienproduktion befindliche Absperrhähne durch den Anbau des Isolierstückes für den Einsatz als .Rbsperrhahn für Gase geeignet zu machen, so daß für diese Anwendungsfälle keine neuen und kostspieligen Produktionsmittel (Werkzeuge, Gußformen) benötigt werden.The present invention now has the aim of existing systems by subsequent attachment of an insulating piece to the existing shut-off valve accordingly to secure the regulations. This solution also offers the possibility of Shut-off valves in series production by adding the insulating piece to make it suitable for use as a .Rbperrhahn for gases, so that for these applications no new and expensive means of production (tools, molds) are required will.

Am Beispiel der Fig. 1 ist der prinzipielle Gedanke dargestellt.The basic idea is shown using the example of FIG. 1.

Lösung A) Der Absperrhahn 1 #ird an der einen Stirnseite seines Gewindestutzens mit z. Bo sechs gegeneinander um 600 versetzten Bohrungen 2 versehen, Das Isolierstück 3 besitzt ein Außengewinde, mit dem es im Innengewinde des Absperrhahnes verschraubt wird. An der Stirnseite des Isolierstückes sind entsprechend der Lage der Bohrungen an der Stirnseite des Absperrhahnes ebenfalls sechs Bohrungen angebracht, in denen je ein Stift 4 oder eine Kugel sitzen Nach Einschrauben des Isolierstückes in den Absperrhahn werden diese Elemente in die entsprechenden Bohrungen des Anschlußhahnes hineingedrückt, entweder durch Federn 5 (oder sonstige elastische Elemente) oder durch Stiftschrauben 6. Dadurch wird das Isolierstück unlösbar mit dem Absperrhahn verankert, wie es die Vorschrift verlangt~ Die elektrische Isolierung ("Trennstrecke") selbst erreicht man durch ein zwischen dem äußeren Teil 7 und dem inneren metallischen Gewindestück 8 eingeschraubtes Gewindestück aus einem Kunststoff 9 Die Verankerung der Elemente erfolgt beispielsweise durch Vergießen oder Ausspritzen des zunächst freigelassenen Raumes 10 mit einem Kunststoff (Thermoplast, Duroplast, aushärtender Zweikomponentenkleber). Durch Einfräsungen 11 im Gewindestück 8 und Bohrungen 12 im Isolierstück 3 werden die Teile gegen Verdrehen gesichert.Solution A) The shut-off valve 1 # is attached to one end of its threaded connector with z. Bo provided six holes 2 offset from one another by 600, the insulating piece 3 has an external thread with which it is screwed into the internal thread of the stopcock will. On the front side of the insulating piece are according to the position of the holes on the face of the stopcock there are also six holes in which a pin 4 or a ball sit after screwing the insulating piece into the These elements are shut-off valves in the corresponding holes in the connection valve pressed in, either by springs 5 (or other elastic elements) or by means of studs 6. This makes the insulating piece non-detachable from the shut-off valve anchored as required by the regulation ~ The electrical insulation ("isolating distance") itself is achieved by a between the outer part 7 and the inner metallic Threaded piece 8 screwed-in thread piece made of plastic 9 The anchorage of the elements is carried out, for example, by potting or injection molding of the first space 10 left free with a plastic (thermoplastic, thermosetting plastic, hardening Two-component adhesive). Through millings 11 in the threaded piece 8 and holes 12 In the insulating piece 3, the parts are secured against twisting.

Lösung B) Diese Lösung unterscheidet sich von der beschriebenen dadurch, daß die Verankerung des Isolierstückes mit dem Absperrhahn an der Sechskantschlüsselfläche 13 des Abspetrhahnes erfolgt. Zu diesem Zweck besitzt das Isolierstück einen hutförmigen Ansatz 14, der sich beim Einschrauben des Isolierstückes in den Absperrhahn über dessen Sechskant schiebt.Solution B) This solution differs from the one described in that that the anchoring of the insulating piece with the stopcock on the hexagon wrench surface 13 of the Abspetrhahnes takes place. For this purpose, the insulating piece is hat-shaped Approach 14, which is about when screwing the insulating piece into the stopcock whose hexagon pushes.

Die unlösbare Verankerung erfolgt z0 Bo durch Stiftschrauben 15, die bis zum Anschlag auf den Sechskant des Hahnes aufgeschraubt werden, Diese Lösung ist entsprechend auch anwendbar bei Vierkant-oder sonstigen Schlüsselflächen.The permanent anchoring is done z0 Bo by studs 15, the screwed onto the hexagon of the tap as far as it will go, this solution can also be used accordingly for square or other wrench surfaces.
