    Frosthaim   fir Wasserleitungen. 



   Bisher hat man, um das Einfrieren der üblichen Wasserleitungshähne zu verhindern, einen kleinen, unmittelbar an die Druckleitung angeschlossenen Nebenhahn (etwa an der in der Zeichnung durch den Pfeil P angedeuteten Stelle) vorgesehen, der bei Frost oder Frostgefahr ständig geöffnet blieb. Diese Anordnung hat den Nachteil, dass die Sprühwirkung des unter hohen Druck und gegenüber der normalen Ausmündung versetzt austretenden Strahles das   Abflussbecken   und schliesslich auch dessen Abfluss selbst stark vereiste. 



   Dieser Übelstand wird beim Frosthahn gemäss der Erfindung verhindert, indem bei Frostgefahr über eine besondere Umführungsleitung ein stark gedrosselter, daher praktisch fast druckloser Ausfluss des Wassers durch den   Haupthahn   erfolgt. 



   In der Zeichnung bezeichnet   1 das   Gehäuse des Hahnes, 2 den Absperrkegel, der die Druckleitung 3 von der   Abflussleitung   4 trennt. Mit 5 ist ein seitlich oberhalb der Druckleitung an den Gehäusehals angegossener Putzen bezeichnet, der eine horizontale Durchgangsbohrung 6 erhält, deren   Aussenmündung   durch den Pfropfen 7 verschlossen wird und die mit dem Raum 8 oberhalb des Absperrkegels 2   kommuni-

    Frosthaim for water pipes.



   So far, in order to prevent the usual water main taps from freezing, a small auxiliary tap connected directly to the pressure pipe (e.g. at the point indicated by the arrow P in the drawing) has been provided, which remained open at all times when there was frost or danger of frost. This arrangement has the disadvantage that the spray effect of the jet exiting under high pressure and displaced from the normal outlet, the drainage basin and ultimately also its drainage itself strongly iced up.



   This inconvenience is prevented with the frost tap according to the invention in that, if there is a risk of frost, a strongly throttled, therefore practically almost pressureless outflow of the water takes place through the main tap via a special bypass line.



   In the drawing, 1 denotes the housing of the tap, 2 the shut-off cone which separates the pressure line 3 from the discharge line 4. A plaster cast laterally above the pressure line on the housing neck is denoted by 5, which has a horizontal through-hole 6, the outer opening of which is closed by the plug 7 and which communicates with the space 8 above the shut-off cone 2.
 EMI1.1
 No amount of water exerting any spray effect from the pressure line 3 via the channels 9, 6, the space 8 and the outlet pipe 11 is going on.

Claims (1)

Bohrungen in einem Gehäuseanguss oberhalb der Druckleitung gebildet und durch eine Drosselschraube od. dgl. gesteuert wird. Bores are formed in a housing sprue above the pressure line and controlled by a throttle screw or the like. 3. Hahn nach Anspruch 2, dadurch gekennzeichnet, dass der Gehäuseanguss zwei einander schneidende Durchgangsbohrungen erhält, von denen die eine aussen durch einen Pfropfen verschlossen wird und innen mit dem Auslaufrohr kommuniziert, während die andere Bohrung aussen durch die Drosselschraube verschlossen und innen mit der Druckleitung verbunden ist. EMI1.3 **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. 3. Tap according to claim 2, characterized in that the housing sprue receives two intersecting through bores, one of which is closed on the outside by a plug and communicates inside with the outlet pipe, while the other bore is closed on the outside by the throttle screw and inside with the pressure line connected is.
