Description

Im zusatzpatent 937 790 ist, ebenso wie im zugehörigen Hauptpatent 933 952, eine membrangesteuerte Wassermangelsicherung dargestellt, bei der das Langsamzündventil als undichtes axial geführtes Tellerventil ausgebildet ist. Die Erfindung betrifft eine Verbesserung der im Zusatzpatent 937 79o behandelten Ausführungsform, bei der ein auf einem abdichtenden kragenförmigen Sitz aufliegender Ventilteller auf einer Ventilstange derart lose geführt ist, daß die Flüssigkeit zwischen Ventilstange und Ventilteller gedrosselt ab- oder zuströmt. Erfindungsgemäß ist , die Ventilstange konisch ausgebildet und in axialer Richtung relativ zum Ventilsitz einstellbar. Es wird dadurch möglich, die Drosselung, die zwischen Ventilstange und Teller stattfindet, zu verzögern oder zu verkleinern und damit den. Grad der Langsamzündung zu verändern.In the additional patent 937 790 , as in the associated main patent 933 952, a diaphragm-controlled water shortage protection device is shown, in which the slow ignition valve is designed as a leaky, axially guided poppet valve. The invention relates to an improvement of the embodiment dealt with in additional patent 937 79o, in which a valve disk resting on a sealing collar-shaped seat is loosely guided on a valve rod in such a way that the liquid between the valve rod and valve disk flows in or out in a throttled manner. According to the invention, the valve rod is conical and adjustable in the axial direction relative to the valve seat. This makes it possible to delay or reduce the throttling that takes place between the valve stem and plate, and thus the. Change the degree of slow ignition.

Ein Ausführungsbeispiel der Erfindung ist in der Abbildung dargestellt. Im Ventilgehäuse i ist ein kragenförmiger Ventilsitz 2 angebracht, auf dem ein Ventilteller 3 aufliegt. Der Ventilteller 3 ist von einem konischen Ventilschaft 4 zentrisch durchdrungen. Der Ventilstift 4 sitzt an einer Stellschraube5, die in das Gehäuse i eingeschraubt ist. 'Eine Schraubkappe 6 schließt das Gehäuse i dicht ab. Das in Pfeilrichtung aus der nicht dargestellten Membrankammer abströmende Wasser wird beim Durchtritt zwischen Ventilteller 3 und Ventilstift 4- gedrosselt, ehe es durch den Kana117 abfließt. Diese Drosselung ist durch die Stellschraube 5 einstellbar, wobei der Stift 4 mehr oder weniger weit durch den Ventilteller 3 hindurchragt. Nach dem Einstellen der Stellschraube 5 wird das Gehäuse i durch die Schraubkappe verschlossen, so daß eine unbefugte Verstellung vermieden wird.An embodiment of the invention is shown in the figure. In the valve housing i a collar-shaped valve seat 2 is attached, on which a valve plate 3 rests. The valve disk 3 is centered by a conical valve stem 4 penetrated. The valve pin 4 is seated on an adjusting screw 5, which is inserted into the housing i is screwed in. A screw cap 6 seals the housing i tightly. This in Direction of arrow from the membrane chamber, not shown, flowing water is throttled when passing between valve plate 3 and valve pin 4- before it through the Kana117 flows off. This throttling can be adjusted by means of the adjusting screw 5, wherein the pin 4 protrudes more or less far through the valve disk 3. After adjusting the adjusting screw 5, the housing i is through the screw cap locked so that unauthorized adjustment is avoided.

Strömt das Wasser in umgekehrter Richtung aus dem Kanal 7 heraus, wird der Ventilteller 3 vom Sitz 2 abgehoben, so daß keine Drosselung stattfindet.If the water flows out of channel 7 in the opposite direction, the valve disk 3 is lifted from the seat 2 so that no throttling takes place.
