Description

Rückschlagventil für Hauswasserleitungen Es ist bekannt, in die Hausanschlüsse von Wasserleitungen ein Rückschlagventil einzubauen, um das Ansaugen von Schmutzwasser zu verhindern. Die bisher für diesen Zweck bekannt gewordenen Ventile bieten indessen keine Sicherheit dafür, daß sie dauernd betriebsfähig sind. Die Vorrichtungen bleiben jahrelang ohne Wartung, und es bilden sich in ihnen Inkrustationen, welche verhindern, daß das Rückschlagventil seinen Zweck erfüllt, wenn einmal ein Benutzungsfall eintritt.Check valve for domestic water pipes It is known in the house connections of water pipes to install a check valve to prevent the suction of dirty water to prevent. The valves previously known for this purpose, however, offer no guarantee that they will always be operational. The devices remain for years without maintenance, and incrustations form in them which prevent that the check valve fulfills its purpose, once a case of use occurs.

Dieser übelstand wird nach der Erfindung dadurch beseitigt, daß nicht nur, wie an sich bekannt, der Ventilsitz und die Kugel, sondern auch das Gehäuse aus einem vom Wasser nicht angreifbaren Stoff, z. B. Hartgummi, hergestellt werden, so daß also das Wasser innerhalb des Rückschlagventils nur mit einem Stoff in Berührung kommt, an dem sich Inkrustationen nicht bilden können.This disadvantage is eliminated according to the invention in that not only, as is known per se, the valve seat and the ball, but also the housing made of a substance that cannot be attacked by water, e.g. B. hard rubber, are produced, so that the water inside the check valve only comes into contact with one substance comes on which incrustations cannot form.

Ein mit diesem Rückschlagventil ausgerüsteter Hausanschluß bleibt ohne jede Wartung für viele Jahre völlig gebrauchsfähig. Bei jedem Aufhören des Zuflusses erfolgt stets mit Sicherheit ein selbsttätiges Absperren des Hausnetzes.A house connection equipped with this check valve remains Can be used for many years without any maintenance. Each time the Inflow always takes place with security an automatic shut-off of the house network.

In der Zeichnung ist eine Ausführungsforen der Vorrichtung ;dargestellt. Es zeigen: Abb. i schematisch einen Hausanschluß mit eingebautem Rückschlagventil, Abb. 2 einen Längsschnitt durch das Ventil, Abb.3 einen Querschnitt. Wie Abb. i zeigt, wird in die von dem Straßenrohra zu dem Hausnetz b führende Anschlußleitung c das Rückschlagventild angeordnet, so daß kein Wasser aus dem Hausnetz zum Straßenrohr zurückströmen kann. Das Ventil besteht, wie die Abb. 2 und 3 zeigen, aus einem Messinggehäuse e, welches eine Hartgummibüchse f enthält, die durch einen Deckelg abgeschlossen ist. An der Stirnseite lt der Büchse ist der Ventilsitz ausgebildet; als Ventilkörperdient die Gummikugel!. Eine derartige Vorrichtung bleibt dauernd brauchbar, so daß selbst nach längerer Nichtbenutzung das Rück$chlagventil sofort in Wirkung tritt, wenn. vom Straßenrohr a aus .das Wasser abgelassen wird. Das Hausnetz bleibt auch dann gefüllt, und es kann auch (dann kein Wasser durch die Zapfstellen in . das. Netz eindringen.In the drawing, an embodiment of the device is shown. They show: Fig. I schematically a house connection with a built-in check valve, Fig. 2 is a longitudinal section through the valve, Fig. 3 is a cross section. As Fig. I shows, is in the connection line leading from the street pipe a to the house network b c the check valve arranged so that no water from the house network to the road pipe can flow back. As shown in Figs. 2 and 3, the valve consists of a brass housing e, which contains a hard rubber bushing f, which is closed by a lid is. The valve seat is formed on the end face of the bushing; serves as a valve body the rubber ball !. Such a device remains permanently usable, so that even after a long period of non-use the non-return valve takes effect immediately if. from the road pipe a. the water is drained. The house network remains even then filled, and it can also (then no water through the taps in. the. network penetration.
