KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Das Sicherheitsventil ist auf beiliegender Zeichnung inThe safety valve is shown in the accompanying drawing in Fig. ι im Längenschnitt,Fig. Ι in longitudinal section, Fig. 2 im Verticalquerschnitt undFig. 2 in vertical cross section and Fig. 3 im Grundrifs dargestellt.Fig. 3 shown in outline. Das gufseiserne Gehäuse A ist auf dem Kessel festgebolzt und das Rohr M führt bis dicht auf den Boden des Kessels nieder. Es mündet oben in zwei Kanäle, die sich in der auf dem Gehäuse A befestigten Kappe B vereinigen. Innerhalb letzterer ist auf dem Gehäuse A ein Rothgufsring C befestigt, der den Sitz des sich nach dem Innern von A zu öffnenden Ventils D bildet. Das Ventil D ruht mit einem centralen Kerb auf dem Stift E, der sich auf das eine Ende des um den Drehpunkt G schwingenden Hebels F stützt. D E und F sind nur durch Ketten mit einander verbunden. Der Druck auf das andere Ende des Hebels F, durch den das Ventil an seinen Sitz gedrückt wird, wird von dem Hebel J mit dem Gewicht K ausgeübt. Der Hebel J stützt sich nämlich nahe seinem Drehpunkt auf den in Stopfbüchse / gleitenden und auf Hebel F aufstehenden Stift H. Durch Verschiebung des Gewichtes K kann in der bekannten Weise der Drück regulirt werden, unter dem sich Ventil D öffnet. Der Hahn L dient zum Ablassen des sich im Gehäuse A sammelnden Wassers.The cast iron housing A is bolted to the boiler and the pipe M leads down tightly to the bottom of the boiler. It opens into two channels at the top, which unite in the cap B attached to the housing A. Inside the latter, a Rothgufsring C is attached to the housing A , which forms the seat of the valve D which is to be opened towards the inside of A. The valve D rests with a central notch on the pin E, which is supported on one end of the lever F swinging around the pivot point G. DE and F are only connected by chains. The pressure on the other end of the lever F, by which the valve is pressed against its seat, is exerted by the lever J with the weight K. The lever J is in fact supported near its pivot point on the pin H, which slides in the stuffing box / and rests on the lever F. By shifting the weight K , the pressure at which valve D opens can be regulated in the known manner. The tap L is used to drain the water that has collected in housing A. Der Zweck dieses Apparates ist, die Kesselexplosionen dadurch zu verhüten, dafs bei zu hoher Spannung das Wasser und nicht der Dampf hinausgeschafft wird, womit der zu hohen Pressung schneller abgeholfen wird, als beim Auslassen des Dampfes.The purpose of this apparatus is to prevent boiler explosions by high tension the water and not the steam is carried out, with which the too high Pressing is remedied more quickly than by letting out the steam. Paten τ-An spruch:Sponsorship τ claim: Ein Sicherheitsventil für Dampfkessel, bei dem sich das eigentliche Ventil D durch den Stift E auf den Hebel F stützt, welche Theile durch Ketten verbunden sind und sich im Gehäuse A befinden, während das Ventil durch den belasteten Druckhebel J vermittelst des in einer Stopfbüchse / gleitenden Stiftes II geschlossen erhalten wird.A safety valve for steam boilers, in which the actual valve D is supported by the pin E on the lever F , which parts are connected by chains and are located in the housing A , while the valve is supported by the loaded pressure lever J by means of the one sliding in a stuffing box Stift II is kept closed.
