Description

KAISERLICHESIMPERIAL

■'PATENTAMT.■ 'PATENT OFFICE.

Die Fig. 1 zeigt einen Schnitt durch den , Hahn, wobei das Ventil e durch den Druck der Flüssigkeit gegen den Ventilsitz gedrückt wird.Fig. 1 shows a section through the valve, the valve e being pressed against the valve seat by the pressure of the liquid.

Fig. 2 zeigt einen Schnitt in derjenigen Stellung beider Ventile c und e, bei der Durchflufs stattfindet. ■'../-.Fig. 2 shows a section in that position of both valves c and e in which flow takes place. ■ '../-.

Durch Drehen der Flügelmutter α wird die Spindel b, welche sich im Obertheil k befindet, mit. der Gummischeibe c hoch und niedrig geschraubt. Beim Hochschrauben der Spindel b wird das Ventil e durch den Druck der Flüssigkeit selbst geschlossen. Da das Ventil e fest an die Gummischeibe h geprefst wird und selbsttätige Dichtung herbeiführt, kann ein Auswechseln der Gummischeibe c erfolgen, ohne dafs der Haupthahn geschlossen zu werden braucht. Das Ventil e des Hahnes dient zugleich in der Stellung der Fig. ι als selbstthätiges Lufteinlafsventil für den Fall, dafs die Leitung entwässert werden soll.By turning the wing nut α , the spindle b, which is located in the upper part k, is with. the rubber washer c screwed high and low. When the spindle b is screwed up, the valve e is closed by the pressure of the liquid itself. Since the valve e is pressed firmly against the rubber washer h and creates an automatic seal, the rubber washer c can be replaced without the main tap having to be closed. The valve e of the cock also serves in the position of FIG. 1 as an automatic air inlet valve in the event that the line is to be drained.

Wird die Leitung wieder angelassen, so schliefst sich das Ventil, e von selbst. Die zweite Dichtung wird durch vollständiges Niederschrauben der Spindel b erreicht.When the line is started again, the valve e closes by itself. The second seal is achieved by screwing down the spindle b completely.

Soll Ausflufs erfolgen, so mufs die Spindel b so weit hoch gedreht werden, dafs die beiden Ventile c und e in die Stellung der Fig. % kommen.Ausflufs effected should be so b must, as far as the spindle turned up, that the two valves c and e.% Are in the position of FIG.

Claims (1)

Patent-Anspruch:Patent claim: Ein Hahn mit Doppelverschlufs, bestehend aus einer losen, durch den Druck der Flüssigkeit oder des Gases gegen ihren Sitz h gepreisten Ventilscheibe e in Verbindung mit einem zweiten Ventil cd, dessen nach unten verlängerte Spindel b1 beim Niederschrauben die Ventilscheibe e von ihrem Sitz abdrückt, wobei in der Mittelstellung beider Ventile (Fig. 2) der Hahn geöffnet ist, während durch weitere Abwärtsbewegung der Ventilspindel das obere Ventil geschlossen wird.A cock with Doppelverschlufs consisting cd of a loose, by the pressure of liquid or gas against its seating h price rating valve disc e in conjunction with a second valve whose according extended below the spindle b 1 during screwing down the valve disc e from its seat pulls the trigger, whereby in the middle position of both valves (Fig. 2) the cock is open, while the upper valve is closed by further downward movement of the valve spindle.
