Bekanntlich müssen die Steigrohre von Ventilbrunnen, um sie vor dem Einfrieren zu schützen, mit einer Vorrichtung versehen sein, die bei geschlossenem Brunnenventil ein Ablaufen des in dem Steigrohre befindlichen Wassers gestattet, bei geöffnetem Ventil dagegen nach aufsen geschlossen ist.It is well known that the risers of valve wells need to be closed before freezing protect, be provided with a device that drains when the well valve is closed of the water in the riser pipe, but with the valve open is closed to the outside.
Fig. ι zeigt den unteren Theil eines mit derselben versehenen Ventilbrunnens im Verticalschnitt, Fig. 1 shows the lower part of one with the same valve well provided in vertical section,
Fig. 2 im Horizontalschnitt nach A-B der Fig. i.Fig. 2 in horizontal section according to AB of Fig. I.
In dem Ventilgehäuse α des Brunnens ist in geringer Höhe über dem von der Ventilstange b bewegten Ventil c die Entwässerungsvorrichtung angeordnet. Dieselbe besteht aus einem. Rohr f mit einer weiteren Bohrung g, einer von der ersteren durch Bund h getrennten engeren Bohrung i und einer das Ende des Rohres verschliefsenden, mit Oeffnung k versehenen Verschlufsschraube /, deren nach innen gekehrte Fläche als Ventilsitz ausgebildet ist (Fig. 2). In dem Rohr f ist ein mit Kanal m und seitlicher Oeffnung η versehener Ventilkegel ο angeordnet, der durch eine Feder ρ stets von seinem Sitz abgehoben wird und mit seinem vorderen Ende in die Bahn des Brunnenventilkegels c hineinragt.In the valve housing α of the well, the drainage device is arranged at a low height above the valve c moved by the valve rod b. It consists of one. Tube f with a further bore g, a narrower bore i separated from the former by collar h and a screw plug / with opening k which closes the end of the tube and whose inwardly facing surface is designed as a valve seat (Fig. 2). In the tube f there is a valve cone ο provided with a channel m and a lateral opening η , which is always lifted from its seat by a spring ρ and protrudes with its front end into the path of the well valve cone c.
Durch diese Anordnung ist bei geschlossenem Brunnenventil c ein Abfliefsen des Wassers aus dem Steigrohr durch den Kanal m, die Oeffnung n, die Bohrung g und Oeffnung k nach aufsen möglich, während beim Oeffnen des Brunnenventils dessen Kegel c unter Ueberwindung der Feder ρ das Entwässerungsventil m η ο zurückschiebt und durch Aufpressen seines Kegels 0 auf den Sitz Z schliefst.With this arrangement, when the well valve c is closed, the water from the riser pipe can flow out through the channel m, the opening n, the bore g and the opening k , while when the well valve is opened, its cone c , overcoming the spring ρ , opens the drainage valve m η ο pushes back and closes by pressing its cone 0 onto the seat Z.
