   In Fig 2 ist das Kesselabsperrventil a auf der Schraubenspindel b schsial verschiebbar, während letztere im Gegensatz zu Fig. 1 lediglich eine Drehung und keine achsiale Verschiebung beim Anstellen des Ventils erfährt. Der   Ventilkörper     a   wird zur   Ermöglichung   der achsialen Verschiebung bzw. zur Verhinderung der Drehung beispielsweise an Rippen des Ventilgehäuses geführt ; das Gleiche   trifft   auch für das Ventilgehäuse c zu, welches bei Drehung der Ventilspindel d ebenfalls eine achsiale Verschiebung erfährt. Die Übertragung der Drehbewegung von einer Spindel zur anderen erfolgt durch Zahnräder 1,   .   



   In beiden Ausführungsfonnen kann das Handrad anstatt auf der Ventilspindel b auch auf der   Ventilspindel d angeordnet weiden und   von letzterer aus der Antrieb erfolgen. 



    PATENT ANSPRÜCHE :  
1. Kesselabsperrventil in Verbindung mit einem Auslassventil, gekennzeichnet durch die Anordnung eines Rückschlagventils zwischen beiden Ventilen, welches den Austritt von Kesselinhalt usw. auch dann verhindert, wenn   Absperr-und Auslassventil gleichzeitig   ganz oder teilweise geöffnet sind.

   In FIG. 2, the boiler shut-off valve a is axially displaceable on the screw spindle b, while the latter, in contrast to FIG. 1, only experiences a rotation and no axial displacement when the valve is turned on. The valve body a is guided, for example, on ribs of the valve housing to enable axial displacement or to prevent rotation; the same also applies to the valve housing c, which also experiences an axial displacement when the valve spindle d is rotated. The transmission of the rotary motion from one spindle to the other takes place through gears 1,



   In both embodiments, the handwheel can be arranged on the valve spindle d instead of on the valve spindle b, and the drive can take place from the latter.



    PATENT CLAIMS:
1. Boiler shut-off valve in connection with an outlet valve, characterized by the arrangement of a non-return valve between the two valves, which prevents the boiler contents etc. from escaping even if the shut-off valve and outlet valve are fully or partially open at the same time.

Claims (1)

2. Kesselabsperrventil nach Anspruch 1, dadurch gekennzeichnet, dass die Öffnungs-und Schliessbewegung des Kesselabsperrventils gegebenenfalls durch Hebel (f) oder durch Zahnräder (l, n) als Schliess-oder OSnungsbewegung auf das Auslassventil oder umgekehrt vom Auslassventil zum Absperrventil übertragen wird, damit, wenn bei geschlossenem Absperrventil gefördert wird, die Förderflasigkeit ins Freie entweichen kann und unzulässig hohe Drücke in der Förderleitung vermieden werden. EMI2.1 2. Boiler shut-off valve according to claim 1, characterized in that the opening and closing movement of the boiler shut-off valve is transmitted, if necessary, by lever (f) or by gears (l, n) as a closing or opening movement to the outlet valve or vice versa from the outlet valve to the shut-off valve, so that , if the pumping is carried out with the shut-off valve closed, the pumping liquid can escape into the open and impermissibly high pressures in the delivery line are avoided.
