Patentirt im Deutschen Reiche vom i. August 1899 ab.Patented in the German Empire from i. August 1899.

Die Erfindung betrifft eine Sicherheitsvorrichtung für stationäre Dampfmaschinen, durch die der Dampf sofort abgesperrt und die Maschine von irgend einer Stelle aus bei Unfällen angehalten werden kann.The invention relates to a safety device for stationary steam engines by which shut off the steam immediately and the machine from anywhere in the event of an accident can be stopped.

Bisher war es sehr schwierig, mit dem Maschinenführer so in Verbindung zu treten, dafs er bei Unfällen, die in entlegenen Räumen stattfanden, die Maschine anhielt.So far it has been very difficult to get in touch with the machine operator in such a way that that he stopped the machine in the event of accidents which took place in remote rooms.

Bei der den Gegenstand der Erfindung bildenden Vorrichtung wird dies erreicht durch ein Flügelrad, das auf der Spindel eines Absperrventils befestigt und in einem geschlossenen Gehäuse angeordnet ist, in welches Druckmittel aus der Hauptleitung durch ein Rohr eingeführt wird, dadurch, dafs man einen Hahn oder ein Ventil an dem Rohr öffnet, das unter gewöhnlichen Verhältnissen abgesperrt gehalten wird.In the device forming the subject of the invention this is achieved by an impeller that is mounted on the spindle of a shut-off valve and in a closed Housing is arranged in which pressure medium from the main line through a pipe is introduced by opening a tap or valve on the pipe that is below kept closed to normal circumstances.

Fig. ι zeigt in Seitenansicht ein gewöhnliches Absperrventil in dem Dampfzuleitungsrohr einer Dampfmaschine, mit der selbstthätigen Absperrvorrichtung versehen,Fig. Ι shows a side view of an ordinary shut-off valve in the steam supply pipe of a Steam engine, provided with the automatic shut-off device,

Fig. 2 eine Oberansicht mit Schnitt hiervon,Fig. 2 is a top view with a section thereof,

Fig. 3 einen senkrechten Schnitt nach Linie 3-3 von Fig. ι undFig. 3 is a vertical section along line 3-3 of Fig. Ι and

Fig. 4 einen Querschnitt nach Linie 4-4 von Fig. 2.FIG. 4 shows a cross section along line 4-4 of FIG. 2.

In bekannter Weise ist an dem Absperrventil A einer gewöhnlichen Dampfmaschine das vom Kessel kommende Dampfzuleitungsrohr B und das Dampfrohr C angeschlossen, das nach der Betriebsdampfmaschine führt. In a known manner, the steam feed pipe B coming from the boiler and the steam pipe C , which leads to the operating steam engine, are connected to the shut-off valve A of an ordinary steam engine.

Die Ventilspindel f ist mit dem üblichen Handrad g versehen, und um diese Spindel ist gemäfs vorliegender Neuerung das dampfdichte Gehäuse D angeordnet.The valve spindle f is provided with the usual handwheel g , and according to the present innovation, the steam-tight housing D is arranged around this spindle.

Vom Dampfrohr C führt ein Zweigrohr d ab, in welches ein Hahn h oder anderes Absperrorgan eingeschaltet ist, und dies Zweigrohr d mündet, wie Fig. 3 zeigt, bei i tangential in das Gehäuse D aus, während an der unteren Seite des letzteren ein Ausblaserohr j abführt. An der Achse k des Hahnes h sitzt ein Arm m, der unter gewöhnlichen Verhältnissen den Hahn geschlossen hält, so dafs Dampf in das Gehäuse D nicht eintreten kann.From the steam pipe C a branch pipe leads d AB, in which a cock h or other shut-off element is turned on, and this branch pipe d discharges, as FIG. 3 shows, in i tangentially into the housing D, while the latter to the lower side of an exhaust pipe j leads away. On the axis k of the valve h there is an arm m which, under normal circumstances, keeps the valve closed so that steam cannot enter the housing D.

Von diesem Arm m führt ein Draht, Schnur oder dergl. ρ nach den einzelnen Räumen des Gebäudes, in welchem sich die Dampfmaschine befindet. Auf der Spindel f des Absperrventils A sitzt innerhalb des Gehäuses D ein Flügelrad H fest, dessen tangentiale Flügel q r verschieden lang sind, und zwar in einer solchen Stellung, dafs ein Dampfstrahl aus dem Zweigrohr d auf die Flügel trifft und das Rad und die Spindel f dreht, sobald Hahn h geöffnet wird.From this arm m a wire, cord or the like. Ρ leads to the individual rooms of the building in which the steam engine is located. An impeller H is firmly seated on the spindle f of the shut-off valve A within the housing D , the tangential blades qr of which are of different lengths, in such a position that a jet of steam from the branch pipe d hits the blades and the wheel and the spindle f turns as soon as tap h is opened.

Unter gewöhnlichen Verhältnissen wird zum Oeffnen und Schliefsen des Absperrventils das Handrad g benutzt. Handelt es sich aber darum, ohne in den Maschinenraum selbst zu Under normal circumstances, the handwheel g is used to open and close the shut-off valve. But is it a matter of without going into the engine room itself

Claims

go to shut down the machine for some reason, arm m can be lifted from any room in the building by pulling the cord ρ and cock h opened, and then a jet of steam from the branch pipe d pours into the housing D, the meets the blades rq and the impeller H turns so that the shut-off valve is closed by means of the spindle f.

By attaching the device described, the usual handling the shut-off valve is not hindered in any way, as would be the case if a shut-off device is arranged with straps. For the present purpose there are devices known at which steam is taken from another source, but with these devices it is not only the regular one Use of the shut-off valve is significantly hampered, but it also gets the steam out a special steam line is fed to a motor and the full pressure is maintained, after the shut-off valve is closed.

These inconveniences are avoided with the present shut-off device. As the impeller is arranged directly on the spindle of the shut-off valve, so it does not offer the usual use of this spindle Obstacle. This also means that the steam BEZW from the machine side of the shut-off valve.

is taken directly from the inlet pipe of the machine, the full steam power is available to immediately transmit the power required to close the shut-off valve to the impeller. In addition, such steam is blown out of the housing D after it has taken effect. Furthermore, since the shut-off valve is immediately closed by the action of the steam from the inlet pipe of the machine and the steam is shut off against the impeller when the shut-off valve is closed, there is also no steam escape from the housing D, and this is essential when the machine is restarted leave resp. wants to open the throttle valve again by hand.

Patenτ claim:

Device for shutting off the hydraulic fluid in engines, characterized in that an impeller (H) is arranged on the spindle (f) of a shut-off valve (A ) within a closed housing (D) , into which fluid under pressure (steam, etc.) ;) can be let in from the supply line (C) through a pipe (d) , by opening a cock (h) or other shut-off device which is attached to the pipe (d) which is closed under normal conditions.
