KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft Absperrventile mit einer selbsttätigen Schließvorrichtung, welche beim Versagen der Antriebsmaschine oder der mit ihr gekuppelten Dynamomaschine zur Wirkung kommt, so daß beispielsweise ein Durchgehen der Antriebsmaschine nach Reißen des Treibriemens verhindert wird.The invention relates to shut-off valves with an automatic closing device, which in the event of failure of the prime mover or the dynamo coupled to it Effect comes, so that for example a runaway of the prime mover after tearing of the drive belt is prevented.
Gemäß der Erfindung wird beim Versagen des elektrischen Stromes die elektromagnetische Sperrung eines Schlagbolzens aufgehoben, so daß dieser vorschnellt und hierbei den Ventilkörper mittels seiner Spindel auf den Sitz drückt.According to the invention, when the electrical current fails, the electromagnetic Blocking of a firing pin is lifted so that it snaps forward and in doing so opens the valve body by means of its spindle pushes the seat.
Auf der beiliegenden Zeichnung ist ein derartiges Ventil im Schnitt dargestellt.Such a valve is shown in section on the accompanying drawing.
Durch eine Schnecke α und ein auf einerBy a screw α and one on one
Hohlspindel c befestigtes Schneckenrad b Hollow spindle c attached worm wheel b
wird die Öffnung des Absperrventiles dadurch geregelt, daß die an ihrem unteren Ende mit Gewinde versehene Hohlspindel c eine außen zweckmäßig sechskantig ausgeführte Büchse e einstellt. Durch letztere wird die Lage des Ventilkörpers h bestimmt, den das von unten her wirkende Druckmittel zu öffnen bestrebt ist.the opening of the shut-off valve is controlled in that the threaded hollow spindle c at its lower end adjusts an externally expediently hexagonal bushing e . The latter determines the position of the valve body h which the pressure medium acting from below tries to open.
Der Ventilkörper h ist an der Spindel g befestigt, die durch die Hohlspindel c hindurchgeführt ist und über diese hinausragt.The valve body h is attached to the spindle g , which is passed through the hollow spindle c and protrudes beyond this.
Oberhalb der Spindel g ist ein unter dem Druck einer Feder m stehender Schlagbolzen k angeordnet, der in einem Lager i geführt wird. Die Feder m ist so bemessen, daß sie beim Niederdrücken den größten Dampfdruck im Ventil zu überwinden vermag, während das oberhalb des Lagers i auf den Bolzen k verstellbar angeordnete Handrad η zum Spannen der Feder dient.Above the spindle g there is a firing pin k which is under the pressure of a spring m and which is guided in a bearing i. The spring m is dimensioned so that it is able to overcome the greatest vapor pressure in the valve when it is pressed down, while the handwheel η, which is arranged above the bearing i so as to be adjustable on the bolt k, serves to tension the spring.
Senkrecht zur Stange k bewegbar ist ein von einer Stange ρ getragener Sperriegel r angeordnet. Die Stange ρ besitzt ferner einen Anker s, den ein im Stromkreis der Dynamomaschine liegender U-förmiger Elektromagnet t anzieht. Die an dem Bolzen k befestigte Platte / kann sich bei gespannter Feder auf die Nase r stützen und den BoI-zen k in ihrer Lage halten. Das Handrad η kann nun an das Stangenende gedreht werden. A locking bolt r carried by a rod ρ is arranged to be movable perpendicular to the rod k. The rod ρ also has an armature s, which is attracted by a U-shaped electromagnet t located in the circuit of the dynamo machine. The plate / attached to the bolt k can be supported on the nose r when the spring is tensioned and hold the bolt k in its position. The handwheel η can now be turned to the end of the rod.
Wenn der Elektromagnet t stromlos wird, zieht eine Feder ν die in einem Lager 0 geführte Stange ρ zurück, worauf die Nase r den Bolzen k freigibt. Diese drückt auf die Ventilspindel und schließt das Ventil.When the electromagnet t is de-energized, a spring ν pulls the rod ρ guided in a bearing 0 back, whereupon the nose r releases the bolt k. This presses on the valve spindle and closes the valve.
