Description
<Desc/Clms Page number 1>
Selbstschlusshahn mit das Nachströmen des Druckwassers regulierende Nebenventil.
EMI1.1
Druck sichert.
Wenn nämlich infolge plötzlich eintretender Druckschwankungen der Druck in der Wasserleitung auf zwei Atmosphären und darunter sinkt, ist die Möglichkeit vorhanden, dass der durchflussquerschnitt des Tellerventiles, welcher nur durch die Undichtheit des letztoren geschaffen wird, zu klein ist und durch Anbringung von entsprechenden Nuten an der Mantelfläche des Ventiles oder ähnliche Mittel vergrössert werden müsste.
Diese Einregulierung ist mit Schwierigkeiten verbunden und bringt auch den Nachteil mit sich, dass beim Steigen des Flüssigkeitsdruckes auf vier Atmosphären und dariiber das Druckwassor zu rasch in die Kammer des Zwischengehäuses einströmt und ein Schlugen des Selbstschlusshahnes erfolgt.
Gemäss vorliegender Erfindung wird nun der Ventilkolben des Selbstschlusshahnes an der dem Tellerventil zugekehrten Seite mit einem Gummipuffer versehen, welcher sich auf eine im Zwischengehäuse eingebaute und mit Öffnungen für den Durchtritt des Druckwassers versehene Zwischenwand stützt.
EMI1.2

Self-closing tap with secondary valve regulating the flow of pressurized water.
EMI1.1
Pressure secures.
If, as a result of sudden pressure fluctuations, the pressure in the water pipe drops to two atmospheres and below, there is a possibility that the flow cross-section of the poppet valve, which is only created by the leakage of the latter, is too small and by making appropriate grooves on the The outer surface of the valve or similar means would have to be increased.
This adjustment is associated with difficulties and also has the disadvantage that when the liquid pressure rises to four atmospheres and above, the pressurized water flows too quickly into the chamber of the intermediate housing and the self-closing valve is opened.
According to the present invention, the valve piston of the self-closing valve is provided with a rubber buffer on the side facing the poppet valve, which is supported on a partition built into the intermediate housing and provided with openings for the passage of the pressurized water.
EMI1.2
can be, carries the elastic rubber buffer h, which is expediently hollow and the other end is supported on the transverse wall <t / t.
