Abstract

The underground hydrant has an outward leading opening (8) for draining the casing pipe (3) which has a flange which, with an intermediary seal, is bolted to the flange of the water-conducting pipeline (1). The pipe (3) houses an operating rod (7) for a valve (6) for opening and closing the pipeline. The drainage outlet (8) is opened simultaneously with the closing of the water supply so that residual water in the casing pipe can run off. The outlet opens into a chamber (9) which is sealed off from the ground and is connected via one or more boreholes (10) in one casing pipe flange with the intermediary chamber (5) between the two flanges.

Description

Unterflurhydrant . Underground hydrant.

Die Erfindung bezieht sich auf einen UnterflurhydramtenO Bei solchen Hydranten ist zum Entwässerung des Mantelrohres eine Entwässerungsöffnung vorhanden, die in das umgebende Erdreich führt und das Restwasser aus dem Mantelrohr nach außen ableitet, nachdem diese Entwässerungsöffnung nach Abschluß der Wasserzuführung durch das Abschlußventil im Mantelrohr geöffnet wurde. Diese Bauart hat den Nachteil, daß die Entleerungsöffnung, die unmittelbar an das Erdreich grenzt, nur eine beschränkte Möglichkeit besitzt, Restwasser abfließen zu lassen, da das Erdreich sich sehr schnell mit Wasser vollsaugt und kein weiteres Wasser aufnehmen kann. Die restlose Entwässerung des Mantelrohres ist daher nicht möglich. Wasserreste im Mantelrohr bergen die Gefahr in sich, daß sie zu faulen beginnen und bei der Wiederinbetriebnahme des Hydranten das zuströmende Wasser verderben. The invention relates to an underground hydram in such Hydrant, there is a drainage opening for draining the jacket pipe, which leads into the surrounding soil and the residual water from the jacket pipe to the outside derives after this drainage opening through after completion of the water supply the shut-off valve in the jacket pipe has been opened. This type of construction has the disadvantage that the emptying opening, which borders directly on the ground, only limited one Possibility of draining residual water, as the soil is very quickly soaks up with water and cannot absorb any more water. The complete drainage of the jacket pipe is therefore not possible. Residual water in the jacket pipe poses a risk in itself that they start to rot and when the hydrant is restarted spoil the flowing water.

Die Erfindung hat sich die Aufgabe gestellt, das Mantelrohr restfrei zu entwässern. The invention has the task of leaving the casing tube free of residues to drain.

Die Erfindung löst diese Aufgabe dadurch, daß die Entwässerungsöffnung in einen zum Erdreich hin abgeschlossenen Raum mündet, der durch eine oder mehrere Bohrungen im Befestigungsflansch des Hydrnntenunterteils mit dem Zwischenraum zwischen diesem Flansch und demienigen der ongeschlossenen Rohrleitung in Verbindung steht. Auf diese Weise wiJerAustrittsquerschnitt zum Erdreich - und das ist die gesamte Höhe des Ringraumes zwischen den beiden Flanschen - erheblich vergrößert, so daß größe Restwassermengen ungehindert austreten können. Die Entwösserung des Mantelrohres erfolgt somit restlos In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt, Die wasserführende Rohrleitung ist mit 1 bezeichnet sie besitzt einen Verbindungsflansch 2. The invention solves this problem in that the drainage opening opens into a space closed off from the ground, through one or more Holes in the fastening flange of the lower part of the hydraulic system with the space between this flange and demienigen the closed pipeline is in connection. In this way, the outlet cross-section to the ground - and that is the entire Height of the annular space between the two flanges - significantly increased, so that large amounts of residual water can escape unhindered. The dewatering of the jacket pipe thus takes place completely. In the drawing, the invention is in one embodiment shown, The water-carrying pipeline is denoted by 1 it has a connecting flange 2.

Das Mantelrohr Unterflurhydranten hat einen Flansch 4, mit dem es unter Einlage einer Dichtung mit dem Flansch 2 durch nicht näher dargestellte Schraubenbolzen verbunden ist. Die beiden Flanschen bilden zwangsläufig einen Zwischenraum 5, der zum Erdreich hin offen ist.The jacket pipe underground hydrant has a flange 4 with which it with the insertion of a seal with the flange 2 by screw bolts not shown in detail connected is. The two flanges inevitably form a space 5, the is open to the ground.

Im Mantelrohr 3 ist ein durch die Betätigungsstange 7 von oben verschiebbares Ventil 6 angeordnet, durch das das Wasserzuleitungsrohr 1 geöffnet oder verschlossen werden kann.In the jacket tube 3 is a by the actuating rod 7 from above Valve 6 arranged through which the water supply pipe 1 is opened or closed can be.

Um bei geschlossenem Ventil 6 das Restwasser aus dem Mantelrohr 3 ausfließen lassen zu können, ist eine Entwässerungsöffnung 8 vorgesehen, die gleichzeitig mit dem Schließen der Wasserzuführung geöffnet wird. Diese Entwässerungsöffnung 8 mündet in den Raum 9, der zum Erdreich hin abgeschlossen ist. Er steht aber durch eine oder mehrere Bohrungen lo im Flansch 4 mit dem Zwischenraum 5 in Verbindung. Auf diese Weise kann das durch die Entwässerungsöffnung 8 ausfließende Restwasser aus dem Mantelrohr 3 ungehindert austreten und gelangt über den Raum 9 und die Bohrung lo in den stets offenen Zwischenraum 5, von wo es über einen großen Austrittsquerschnitt ins Erdreich abfließt, LeerseiteIn order to remove the residual water from the jacket pipe 3 when the valve 6 is closed To be able to flow out, a drainage opening 8 is provided, which at the same time is opened when the water supply is closed. This drainage opening 8 opens into space 9, which is closed off from the ground. But he stands by one or more bores lo in the flange 4 with the space 5 in connection. In this way, the residual water flowing out through the drainage opening 8 can exit unhindered from jacket pipe 3 and pass through space 9 and the bore lo in the always open space 5, from where there is a large outlet cross-section flows into the ground, Blank page
