Description
Es ist bekannt, daß bei den gebräuchlichen Rohranschlüssen mittels Rohrschelle sowohl im Bohrloch des Hauptrohres als auch des Rohrschellendurchganges Inkrustierungen, z.B. durch Rost, entstehen, welche den Durchgang immer mehr verengen und schließlich ganz zusetzen.It is known that with the usual pipe connections by means of a pipe clamp both Incrustations in the borehole of the main pipe as well as the pipe clamp passage, e.g. caused by rust, which narrow the passage more and more and finally completely to add.
Diese Inkrustierungen der Durchgangsöffnungen werden durch die Beschaffenheit desThese incrustations of the through openings are due to the nature of the

j 5 sich, als in den Durchgangsöffnungen von Rohrschelle und Rohr gerade das durch die Anbohrung bearbeitete Gußeisen ausgesetzt ist, da die sonst etwas mehr schützende Gußhaut fehlt. _j 5 turned out to be in the through openings of the pipe clamp and pipe is exposed to the cast iron machined through the drilling, as the otherwise somewhat more protective cast skin is missing. _
Diesem Übelstand hilft die in der Zeichnung unter Fig. ι dargestellte Neuerung, den drehbar mit der Spindel eines Anbohrventils verbundenen Ventilkegel» mit einem Hohlzylinder a, der Fensteröffnungen für den Wasserdurchgang besitzt, zu versehen, auf die einfachste Art insofern ab, als die Länge I des Hohlzylinders a so bemessen ist, daß er in der Durchgangsöffnung d der Rohrschelle sowohl als auch insbesondere in der Bohrung δ des Rohres deren Auskleidung bildet, gleichviel in welcher Stellung sich der Ventilkegel befindet.This deficiency is helped by the innovation shown in the drawing under FIG. 1, the simplest way to provide the valve cone, which is rotatably connected to the spindle of a tapping valve, with a hollow cylinder a, which has window openings for the passage of water, insofar as the length I of the hollow cylinder a is dimensioned so that it forms the lining in the passage opening d of the pipe clamp as well as in particular in the bore δ of the pipe, regardless of the position in which the valve cone is located.
Die in Fig. 2 dargestellte Ausführung des Ventilkegels zeigt den Hohlzylinder a1 in seiner Länge etwas kürzer bemessen und an dessen freiem Ende m als Schneide ausgebildet. Diese Ausführung ist für diejenigen Fälle gedacht, wo der besseren Wasserbeschaffenheit wegen nur geringe Absetzungen im Bohrloch zu befürchten sind und dadurch die Auskleidung der Bohrung und des Rohres sich als nicht direkt notwendig erweist, trotzdem aber die Möglichkeit geschaffen sein soll, in gewissen Zeiträumen der Sicherheit halber die Bohrung des Rohres säubern zu können. Zu diesem Zweck wird das Ventil durch den Ventilkegel geschlossen, und der, wie gesagt, in der Länge entsprechend bemessene Hohlzylinder schabt dabei durch seine schneidenartige Ausbildung m das Bohrloch des Rohres aus.The embodiment of the valve cone shown in Fig. 2 shows the hollow cylinder a 1 dimensioned somewhat shorter in length and designed at its free end m as a cutting edge. This version is intended for those cases where the better water quality is to be feared because of only minor settlements in the borehole and thus the lining of the borehole and the pipe proves to be not directly necessary, but nevertheless the possibility should be created for safety in certain periods of time to be able to clean the bore of the pipe. For this purpose the valve is closed by the valve plug, and, as stated, in length correspondingly dimensioned hollow cylinder thereby scrapes with its blade-like formation m the well of the tube.
Der Hohlzylinder «2 kann aber auch, wie in Fig. 3 dargestellt, mittels Gewinde oder in sonst geeigneter Weise mit dem Ventilkegel verbunden werden und dabei aus irgendeinem Werkstoff, welcher der jeweiligen Beschaffenheit des Wassers angepaßt ist, z. B. aus Hart-· gummi, hergestellt werden.The hollow cylinder 2 can also, as shown in FIG. B. made of hard rubber.
