Description
Das auf beiliegender Zeichnung dargestellte Ventil hat den Zweck,, als selbsttätige Absperrvorrichtung in Wasserleitungen eingeschaltet zu werden. Dasselbe kann durch einen geringen, von der Durchgangsöffnung des Ventils unabhängigen Druck auf einen Knopf geöffnet werden, und schliefst sich von selbst, nachdem der Druck aufgehört hat. Der beim Schliefsen gewöhnlicher Hähne und Niederdruckventile unvermeidliche Wasserrückschlag wird durch diese Construction vermieden, weil sich der Ventilkegel beim Abschlufs langsam auf den Sitz niederlegt.The valve shown in the accompanying drawing has the purpose, as an automatic shut-off device to be turned on in water pipes. The same can be done by a small, is opened independently of the passage opening of the valve by pressing a button and will close on its own after the pressure stops. The one while sleeping ordinary faucets and low pressure valves inevitable water backflow is caused by Avoided this construction because the valve cone slowly moves onto the Down seat.
Das Ventil besteht aus folgenden Theilen:The valve consists of the following parts:
AA ist der Ventilhauptkörper, welcher sich von dem Körper der bekannten Gumminiederschraubventile nur dadurch unterscheidet, dafs er das Wasser ringförmig überströmen läfst. B ist der Deckel, welcher oben eine einfache Verschraubung mit darin gleitendem, durch Gummi in eigenthümlicher Weise abgedichteten Druckknopf K trägt. Die Theile A und B haben zwischen sich eine dauerhafte Gummimembran und sind bei k durch einen kleinen Kanal verbunden. Ώ ist eine als Abschlufskegel functionirende Combination von zwei Ventilen. AA is the main valve body, which differs from the body of the known rubber screw-down valves only in that it allows the water to flow over in a ring shape. B is the cover, which at the top has a simple screw connection with a push button K sliding in it and sealed in a peculiar manner by rubber. Parts A and B have a permanent rubber membrane between them and are connected at k by a small channel. Ώ is a combination of two valves that functions as a closing cone.
Die Wukungsweise beim Gebrauch des Ventils ist nun folgende:The manner in which the valve is used is now the following:
Das durch die Einflufsöffnung O einströmende Wasser drückt "einmal direct unter den Ring rr, dann aber auch.durch den Kanal k von oben auf die ganze Fläche der Gummimembran g. The water flowing in through the inlet opening O presses "once directly under the ring rr, but then also through the channel k from above onto the entire surface of the rubber membrane g.
Da der Druck von oben "bedeutender ist, so bleibt das Ventil geschlossen. Bei dieser geschlossenen Stellung läfst das kleine Ventilchen υ kein Wasser durch, weil dasselbe durch eine Spiralfeder ί und aufserdem durch die unter den Knopf K drückende Wasserpressung nach oben gezogen wird. Drückt man auf den Knopf K, so wird, weil das Ventilchen ν etwa den doppelten Querschnitt des Kanals k hat, plötzlich über der Gummimembran der Druck stark vermindert, das unter den Ring rr drückende Wasser wird die Membran selbst heben und durch O1 bei voller Oeffnung abfiiefsen. Dieser Abschlufs dauert so lange, bis man den Knopf K losläfst. Dann schliefst sich wieder das Ventilchen ν und das durch den Kanal k einströmende Wasser drückt das Hauptventil fest zu.Since the pressure from above is more important, the valve remains closed. In this closed position, the small valve υ does not let water through because it is pulled upwards by a spiral spring ί and also by the water pressure that is pressed under the button K. Presses If you press the button K, because the valve ν has about twice the cross-section of the channel k , the pressure above the rubber membrane is suddenly greatly reduced, the water pressing under the ring rr will lift the membrane itself and through O 1 when it is fully open This conclusion lasts until you release the button K. Then the valve ν closes again and the water flowing in through the channel k tightly closes the main valve.
