KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Um zu verhindern, daß durch den Standrohranschluß von Hydranten Fremdkörper, wie Steine, Schmutz, in das Innere des Hydranten gelangen können, hat man bereits Ventilver-Schlüsse für die Austrittsöffnung vorgeschlagen. Hierbei befindet sich an der Austrittsöffnung des Hydranten die Hauptabsperrung, und zwar mit dem Nachteil, daß diese Hauptabsperrung mechanisch durch das aufgesetzteTo prevent foreign objects such as Stones, dirt, can get into the interior of the hydrant, you already have valve closures suggested for the outlet opening. This is located at the outlet opening of the hydrant the main shut-off, with the disadvantage that this main shut-off mechanically through the attached
ίο Standrohr bedient werden muß. Derartige Verschlüsse können von Unbefugten leicht geöffnet werden (bei den sog. Kugelventilen durch Herabdrücken der Kugel und bei den Spindelventilen durch einfaches Niederschrauben des Ventil Verschlusses). Diese Ventil verschlüsse sperren ferner die Auslaßöffnung nicht unmittelbar an, sondern unterhalb der Mündung, so daß oberhalb des Ventilverschlusses schädliche Vertiefungen gebildet werden, in denen sich Steine, Sand oder Schmutz ansammeln können, die leicht in das Innere des Hydranten gelangen. Wenn z. B. der Hydrant vom Leitungsdruck abgesperrt wird, so öffnet sich das einfache Kugelventil selbsttätig, und die durch Feder- oder Spindeldruck verschlossenen Ventile lassen sich leicht abwärts drücken, so daß die in der Vertiefung oberhalb des Ventilverschlusses befindlichen Fremdkörper ohne weiteres in den Hydranten hineinfallen. ίο standpipe must be operated. Such Locks can be easily opened by unauthorized persons (with the so-called ball valves by pressing down the ball and, in the case of the spindle valves, by simply screwing it down of the valve closure). These valve closures also do not block the outlet opening directly at, but below the mouth, so that above the valve closure harmful pits are formed in which stones, sand or dirt can accumulate that can easily get inside the hydrant. If z. B. the hydrant is shut off from the line pressure, so opens the simple ball valve is automatic, and the one closed by spring or spindle pressure Valves can be easily pushed down so that those in the recess are above Foreign bodies located at the valve closure can easily fall into the hydrant.
Alle .diese Mißstände sind durch die vorliegende Erfindung beseitigt, indem die Ausflußmündung am Standrohranschluß durch einen Schutzkörper derart abgesperrt wird, daß Vertiefungen, in denen sich Ablagerungen bilden können, vermieden sind. Ferner arbeitet der Absperrschutzkörper selbsttätig. Durch das durchströmende Wasser wird das Ventil geöffnet, während es sich nach Abschluß des Wassers sofort schließt, noch ehe das Standrohr abgenommen ist. Infolge der mit der Ausmündung glatt abschließenden Form des Schutzkörpers ist es schwer, diesen ohne Zuhilfenahme des Wasserdruckes zu heben. Es können daher Unbefugte die Ausflußöffnung nicht freilegen, und den Fremdkörpern ist ein Eindringen in den Hydranten verwehrt.All of these deficiencies are eliminated by the present invention, in that the outflow mouth at the standpipe connection is blocked by a protective body in such a way that depressions in which there are deposits can be avoided. Furthermore, the shut-off protection body works automatically. By the water flowing through the valve is opened, while it is after completion of the Water closes immediately before the standpipe is removed. As a result of the Orifice smoothly closing shape of the protective body, it is difficult to do this without assistance to raise the water pressure. It can therefore not expose the discharge opening unauthorized, and the foreign body is a No entry into the hydrant.
In der Zeichnung stellt Fig. 1 den Hydranten im Gebrauch dar; das Hydrantenventil ist geöffnet, das Standrohr aufgesetzt. In Fig. 2 ist das Hydrantenventil gesperrt und das Standrohr abgenommen sowie die Ausmündung durch den selbsttätigen Absperrschutzkörper nach außen abgesperrt.In the drawing, Fig. 1 shows the hydrant in use; the hydrant valve is open, the standpipe is in place. In Fig. 2, the hydrant valve is locked and the standpipe removed and the opening through the automatic shut-off protection body locked to the outside.
An der Ausmündung der Hydrantenklaue K ist der Absperrkörper V so gelagert, daß er, wie Fig. 2 zeigt, im Ruhezustand des Hydranten die Ausmündung vollkommen verdeckt. Infolge der Form des Absperr körpers V ist es schwierig, von außen die Ausmündung freizulegen. Ein Anschlag A begrenzt den Aufwärtshub des Ventils V. At the opening of the hydrant claw K , the shut-off body V is mounted in such a way that, as shown in FIG. 2, it completely covers the opening when the hydrant is at rest. Due to the shape of the shut-off body V , it is difficult to expose the mouth from the outside. A stop A limits the upward stroke of valve V.
Bei aufgesetztem Standrohr R und geöffnetem Hydrantenhauptventil H (Fig. 1) wird der Schutzkörper V selbsttätig aus dem von ihm gesperrten Durchgang der Ausmündung durch die Wasserströmung herausgedrückt und stellt sich in eine Erweiterung E des Stand-When the standpipe R is in place and the main hydrant valve H is open (Fig. 1), the protective body V is automatically pushed out of the opening through which it is blocked by the water flow and is positioned in an extension E of the stand-
rohres ein, so daß das durchströmende Wasser ihn umfließt. Sobald nun der Wasserdurchfluß am Hydrantenhauptventil H abgesperrt wird, nimmt der Schutzkörper V, noch bevor das Standrohr R abgenommen ist, selbsttätig seine Ruhestellung ein und verdeckt die Ausmündung der Hydrantenklaue K nach außen wieder vollkommen. Die übergestülpte Schutzglocke G dient zum Schütze der Ventilsitzflächen des Klauenanschlusses.a pipe so that the water flowing through it flows around it. As soon as the water flow is shut off at the main hydrant valve H , the protective body V, even before the standpipe R is removed, automatically assumes its rest position and completely covers the mouth of the hydrant claw K to the outside again. The protective bell G placed over it serves to protect the valve seat surfaces of the claw connection.
