    Auslaufhahn   mit Sieherheitsventit zur Verhinderung des Ansaugens von   Unreinlichkeiten   in die Trinkwasserleitung. 



   Die Erfindung bezieht sich auf Sicherheitsventile für Trinkwasserleitungen, welche bei eintretender Saugwirkung die Leitung abschliessen und dadurch das Eindringen von Verunreinigungen in die Leitung verhindern. Gemäss der Erfindung ist dieses Ventil in 
 EMI1.1 
 ausgewechselt werden kann. 



   Die Zeichnung zeigt ein Ausführungsbeispiel eines derartigen Ventiles in Fig. 1 in Vorderansicht, in Fig. 2 im Schnitt. 



   An das Ende des Ansflussrohres a des Hahnes ist ein Ansatzstück   b angeschraubt,   welches in eine Mündung c endet und das Sicherheitsventil enthält. Das letztere kann in   verschiedener   Weise ausgeführt werden. Bei der in der Zeichnung veranschaulichten beispielsweisen   Ausführungsform   ist der Ventilkörper d halbkugelförmig gestaltet und mit einer Stange e versehen, welche in einer Führung f beweglich ist. 



   Der aus der Leitung herrührende Wasserdruck bewirkt bei der Öffnung des Hahnes eine Verschiebung des Ventiles, sodass das Wasser ohne Schwierigkeit ausströmen kann. 



  Sobald der Wasserdurchlauf aufhört, zieht die Schraubenfeder das Ventil wieder auf seinen   Sitz i. zurück   und die Leitung wird von der äusseren Luft abgeschlossen, selbst wenn der Hahn geöffnet ist. Das Ventil wird immer stärker auf seinen Sitz gepresst, wenn der Hahn. sich in solchem   Zustande benndet,   dass er ansaugen kann. Die Stärke der Feder g muss so bemessen sein, dass sin die Öffnung des Ventiles gestattet, sobald das ausströmende Wasser nur einen geringen Druck auf das Ventil   ausübt.

    Outlet tap with safety valve to prevent impurities from being sucked into the drinking water pipe.



   The invention relates to safety valves for drinking water pipes, which shut off the pipe when a suction effect occurs and thereby prevent contaminants from penetrating the pipe. According to the invention, this valve is in
 EMI1.1
 can be exchanged.



   The drawing shows an embodiment of such a valve in Fig. 1 in front view, in Fig. 2 in section.



   At the end of the inlet pipe a of the tap, an attachment piece b is screwed, which ends in an opening c and contains the safety valve. The latter can be carried out in various ways. In the exemplary embodiment illustrated in the drawing, the valve body d is designed hemispherical and provided with a rod e which is movable in a guide f.



   The water pressure from the pipe causes the valve to move when the tap is opened so that the water can flow out without difficulty.



  As soon as the water stops flowing, the coil spring pulls the valve back onto its seat i. back and the line is closed from the outside air, even when the tap is open. The valve is pressed more and more into its seat when the tap. behaves in such a condition that he can suck in. The strength of the spring g must be such that it allows the valve to open as soon as the outflowing water exerts only a slight pressure on the valve.
