PATENTSCHRIFTPATENT LETTERING R. M. DAELEN in DÜSSELDORF. Einseitiges entlastetes Absperrventil.R. M. DAELEN in DÜSSELDORF. Unloaded shut-off valve on one side. Patentirt im Deutschen Reiche vom 23. November 1879 ab.Patented in the German Empire on November 23, 1879. Bei den bis jetzt gebräuchlichen Constructionen entlasteter, einsitziger Absperrventile dient meistens ein kleines Ventil, welches in der Mitte des grofsen angebracht ist, zur Ausgleichung der Spannung.In the constructions of unloaded, single-seat shut-off valves that have been used up to now usually a small valve, which is attached in the middle of the large one, for compensation the tension. In der in beiliegender Zeichnung dargestellten Construction ist dasselbe durch ein Ventil A ersetzt, welches gleichzeitig die Stopfbüchse abdichtet. Das Gewinde der Spindel B beginnt unterhalb desselben und die Ventilglocke C trägt die Schraubenmutter und wird durch den am Deckel befestigten Stift D am Drehen gehindert.In the construction shown in the accompanying drawing, the same has been replaced by a valve A , which at the same time seals the stuffing box. The thread of the spindle B begins below the same and the valve bell C carries the screw nut and is prevented from turning by the pin D attached to the cover. Beim Oeffnen senkt sich zunächst die Spindel B, bis der Ansatz E auf dem Grunde der Stopfbüchse aufliegt, so dafs das Ventil A geöffnet und den Raum F mit dem Abgesperrten G in Verbindung gesetzt hat, so dafs die Spannung ausgeglichen ist.When opening, the spindle B first lowers until the shoulder E rests on the bottom of the stuffing box, so that the valve A has opened and the space F has been connected to the locked G so that the tension is equalized. Patenτ-Ansρruch:Patenτ claim: Die Entlastung des einsitzigen Absperrventils durch das kleine Ventil A, welches gleichzeitig als Gegenlager der Ventilspindel und zum Abdichten der Stopfbüchse im geschlossenen Zustande dient.The relief of the single-seat shut-off valve through the small valve A, which simultaneously serves as a counter bearing for the valve spindle and to seal the stuffing box when closed.
