WILHELM MAYWALD in HALLE a. S. StoTsfrei sich schliefsencles Wasserleitungsventil.WILHELM MAYWALD in HALLE a. S. Shut-free self-closing of the water main valve.
Patentirt im Deutschen Reiche vom 13. Juni 1878 ab.Patented in the German Empire on June 13, 1878.
Dasselbe besteht aus dem Gehäuse mit zwei darin befindlichen Kolben A und B und, dem Hebel H. Der hohle Kolben A hat einen gröfseren Querschnitt als der Kolben B, und wird aus diesem Grunde heraufgetrieben, wodurch das Ventil abschliefst. Unter dem Kolben B befindet sich ein kleines Ventil 0, das sich beim Aufgange des Kolbens b öffnet und dessen Kegel mit zwei Einschnitten ausgestattet ist, so dafs derselbe nicht vollständig abschliefsen kann. Die beiden Kolben A und B sind durch den gleicharmigen Hebel H mit einander verbunden. Der Raum, innerhalb welchem sich der abschliefsende Ventilkörper des Hauptventils A bewegt, ist konisch, so dafs das Oeffnen und Schliefsen der Ausströmungsöffnung nicht plötzlich geschehen kann.The same consists of the housing with two pistons A and B and the lever H. The hollow piston A has a larger cross-section than the piston B, and is therefore driven up, whereby the valve closes. Under the piston B there is a small valve 0 which opens when the piston b opens and whose cone is equipped with two incisions so that it cannot close completely. The two pistons A and B are connected to each other by the lever H of the same arm. The space within which the final valve body of the main valve A moves is conical, so that the opening and closing of the outflow opening cannot occur suddenly.
Drückt man beim Oeffnen des Ventils den Hebel H und damit den Kolben A herunter, so be\vegt sich der Kolben B herauf und es tritt durch das Ventil 0 Wasser unter denselben. Ueberläfst man alsdann das Ganze sich selbst, so wird der Kolben A vermöge des gröfseren Querschnittes von dem Wasserdrucke heraufbewegt, während der Kolben B gleichzeitig heruntergeht, und es wird dabei das unter dem letzteren befindliche Wasser durch die kleinen Einschnitte im Ventilkegel 0 so lange langsam zurückfliefsen, bis das Ventil A geschlossen ist. Der Wasserdruck, der während des Ausfliefsens gesunken war, wird nun durch die allmälige Verengung des Ausflufsquerschnittes nach und nach seine ursprüngliche Höhe wieder erreichen. Um den Stofs des Wassers, welcher beim Schliefsen des Ventils auftreten würde, unschädlich zu machen, ist auch noch der hohle Raum des Kolbens A mit Luft gefüllt und bildet so ein elastisches Polster.If, when opening the valve, one presses the lever H and thus the piston A down, the piston B moves up and water passes under it through the valve 0. If the whole is then left to itself, the piston A is moved up by the water pressure due to the larger cross-section, while the piston B goes down at the same time, and the water under the latter will slowly flow back through the small incisions in the valve cone 0 for so long until valve A is closed. The water pressure, which had fallen during the outflow, will now gradually reach its original level again due to the gradual narrowing of the outflow cross-section. In order to render harmless the substance of the water, which would occur when the valve is closed, the hollow space of the piston A is also filled with air and thus forms an elastic cushion.
Das Ventil schliefst also selbstthätig, weil der Wasserdruck den Kolben A nach oben treibt, und der Schlufs ist stofsfrei, weil der genannte Kolben sich nur langsam nach oben bewegen kann, die Ausflufsöffnung sich nach und nach verengert und das Luftpolster im Kolben A Stöfse verhindert.The valve closes automatically because the water pressure drives piston A upwards, and the closure is free of material because the said piston can only move slowly upwards, the outflow opening gradually narrows and the air cushion in piston A prevents bumps.
