Patentirt im Deutschen Reiche vom 6. Juni i88a ab.'Patented in the German Empire on June 6, 1888. '
Der Absperrhahn besteht im wesentlichen aus dem äufseren Gehäuse A, ähnlich dem der Absperrventile, der Hahnbüchse B und dem kegelförmigen Hahnbolzen C. The shut-off valve consists essentially of the outer housing A, similar to that of the shut-off valves, the valve sleeve B and the conical valve pin C.
In das äufsere Gehäuse A wird die Büchse B entweder mit Verschraubung nach Fig. ι und 2 oder durch Flantschenverbindung nach Fig. 3 und 4 derart eingesetzt, dafs sowohl bei a .als bei b ein dichter Abschlufs hergestellt wird.In the outer housing A , the sleeve B is inserted either with a screw connection according to FIGS. 1 and 2 or by a flange connection according to FIGS. 3 and 4 in such a way that a tight seal is produced at both a .als b.
In der Hahnbüchse B dreht sich der unten offene Hahnbolzen C mit einseitiger Durchgangsöffnung c. Zwischen dem äufseren Hahngehäuse und der Hahnbüchse ist genügender Durchgangsquerschnitt vorhanden, um die Hahnbüchse mit der Durchgangsöffnung in beliebiger Stellung einsetzen zu können.In the tap socket B , the tap bolt C , which is open at the bottom, rotates with a through hole c on one side. There is a sufficient passage cross-section between the outer tap housing and the tap sleeve to be able to insert the tap sleeve with the passage opening in any position.
Der Hahnbolzen C wird, so lange kein Druck von unten auf denselben wirkt, durch eine Scheibe mit Nase und Mutter, Fig. 1 und 2, oder durch eine Schraubenfeder, Fig. 3 und 4, in seiner Stellung gehalten. Sobald jedoch Druck auf den Querschnitt des Bolzens stattfindet, ist eine selbstthätige Dichtung hergestellt, wobei die Handhabung des Hahnes keineswegs erschwert wird.As long as there is no pressure from below on the cock bolt C , it is held in its position by a washer with a nose and nut, FIGS. 1 and 2, or by a helical spring, FIGS. 3 and 4. However, as soon as pressure is exerted on the cross-section of the bolt, a self-acting seal is established, and the handling of the tap is in no way made difficult.
Das Neue und Eigenthümliche an dem Absperrhahn besteht nach Angabe des Erfinders im wesentlichen aus der in beliebiger Stellung in ein Ventilgehäuse emsetzbaren Hahnbüchse B. Es wird hierdurch der Vortheil erzielt, bei Reparaturen die Büchse mit dem Bolzen einfach auswechseln zu können, ohne das Gehäuse aus der Rohrleitung zu entfernen. Aufserdem ist bei leichterer Handhabung und selbsttätigem Abschlufs keine Stopfbüchse erforderlich.According to the inventor, the new and peculiar thing about the stopcock consists essentially of the tap bushing B , which can be inserted into a valve housing in any position Remove pipeline. In addition, with easier handling and automatic closure, no stuffing box is required.
