PATENTAMT.PATENT OFFICE.
Den Gegenstand der Erfindung bildet ein Druckventil für Wasser-, Gas- und Dampfleitungen. The subject of the invention is a pressure valve for water, gas and steam lines.
α ist der Einlaufstutzen; derselbe ist um das Ventilgehäuse b herumgeführt und bildet die Kammer c, die durch Durchbrechungen d mit dem Innern des Ventilgehäuses in Verbindung steht. Auf der Ventilspindel e sind durch ein passendes Zwischenstück f von einander getrennte und symmetrisch gelagerte Dichtungsscheiben g. Unter der unteren Scheibe g liegt eine Unterlagsscheibe h, während die obere Scheibe g an dem Spindelkopfe k anliegt. Die Bethätigung der Spindel erfolgt durch die in den Spindelkopf eingreifende Schraubspindel /, welche mit steilem Gewinde versehen ist. Die Verschraubung m dient als Führung für die Schraubspindel und zum oberen Abschlüsse des Ventilgehäuses. α is the inlet nozzle; the same is passed around the valve housing b and forms the chamber c, which is in communication with the interior of the valve housing through openings d. On the valve spindle e , symmetrically mounted sealing washers g are separated from one another by a suitable intermediate piece f. A washer h lies under the lower disk g , while the upper disk g rests against the spindle head k. The spindle is actuated by the screw spindle /, which engages in the spindle head and is provided with a steep thread. The screw connection m serves as a guide for the screw spindle and for the upper end of the valve housing.
Fig. ι zeigt das geöffnete Ventil im Schnitt. Das Wasser tritt durch den Einlauf α ein, läuft unterhalb des Ventiles durch die Oeffnungen d in das Ventilgehäuse und gelangt durch den Auslauf η in die Leitung. Um das Ventil zu schliefsen, wird durch Drehung der Schraubspindel / der Ventilkörper so weit heruntergedreht, dafs die eine Dichtungsscheibe g unterhalb und die andere oberhalb der Qeffnungen d zu liegen kommt. Durch den vorhandenen Druck werden beide Dichtungsscheiben einen dichten Schlufs bewirken, so dafs das Wasser weder nach oben noch nach unten entweichen kann.Fig. Ι shows the opened valve in section. The water enters through the inlet α , runs below the valve through the openings d in the valve housing and passes through the outlet η into the line. To close the valve, the screw spindle / valve body is turned down so far that one sealing washer g comes to lie below and the other above the openings d. Due to the existing pressure, both sealing washers will create a tight seal so that the water can neither escape upwards nor downwards.
Der wesentliche Vorzug des dargestellten Ventiles gegenüber älteren Ausführungen besteht darin, dafs infolge des doppelten Ventilschlusses eine Bethätigung des Ventils »gegen Druck« nicht stattfindet. Da ferner oberhalb des Ventiles kein Druck vorhanden ist, so bedarf es auch nicht einer besonderen Führung der Ventilspindel wie bei älteren Ausführungen, wo eine dem auf dem Ventile stehenden hohen Druck entsprechende Dichtung vorgesehen werden mufste.The main advantage of the valve shown over older versions is in that, as a result of the double closing of the valve, an actuation of the valve is counteracted Pressure «does not take place. Furthermore, since there is no pressure above the valve, it is necessary there is also no special guidance of the valve spindle as with older versions, where a seal corresponding to the high pressure on the valve is provided had to.
Das Material der Dichtungsscheiben g wird entsprechend der Bestimmung des Ventiles für Wasser-, Gas- oder Dampfleitungen gewählt.The material of the sealing washers g is selected according to the purpose of the valve for water, gas or steam lines.
