Description
Dampfstrahlregel- und Absperrventil für Dampfheizungen. Gegenstand der Erfindung ist ein Dampfstrahlregel- und Absperrventil mit während des Betriebes verstellbaren Ansaugdüsenkanälen und Ansaugöffnung für Dampfheizungen zur Erzielung eines ständigen Kreislaufes des Dampfes.Steam jet control and shut-off valve for steam heating. object the invention is a steam jet control and shut-off valve with during operation adjustable suction nozzle channels and suction opening for steam heating to achieve a constant cycle of steam.
Das Wesentliche der Erfindung liegt darin, daß die Ansaugdüsenkanäle und die Saugöffnung des Saugrohres, durch welches der Mattdampf angesaugt wird, im Dampfstrahlapparat mittels. eines Düsenkegels. zugleich und im gleichen Sinne mit der Veränderung des Frischdampfstrahldüsenquerschnittes verändert werden können, ohne daß die Heizung entleert oder außer Betrieb gesetzt werden braucht.The essence of the invention is that the suction nozzle channels and the suction opening of the suction pipe through which the matt steam is sucked in, in the steam jet device by means of. of a nozzle cone. at the same time and in the same sense can be changed with the change of the main steam jet nozzle cross-section, without the heating system having to be emptied or put out of operation.
Die Zeichnung zeigt eine beispielsweise Anordnung des Dampfstrahlregel- und Absperrventils in Abb. i in geschlossenem Zustande, in Abb. 2 in geöffnetem Zustande.The drawing shows an example of an arrangement of the steam jet control and shut-off valve in Fig. i in the closed state, in Fig. 2 in the open state Conditions.
Der Frischdampf geht im=Sinne der Pfeile vom Eintritt i durch das Frischdampfventil 7, die Düse 2 und die Düsenkernspitze 9 nach der Austritböffnung 3 des Gemisches. Der angesaugte Mattdampf tritt durch die An-Saugöffnung q. ein, durchläuft die Ansaugkanäle 5 und wird nach der Austrittöffnung 3 mitgerissen und erneut in die Heizanlage gebracht. Der Düsenkegel 6 ist mit dem Ventilkegel 7 mittels eines Düsenkerns 8 so verbunden, daß er sich nur um seine eigene Achse drehen kann, aber gezwungen ist, alle Längsbewegungen des Ventilkegels mitzumachen. Die Düsenkernspitze 9 bildet die Spitze des Düsenkegels 6 und ist mit ihm so verbunden, daß sie jede Längsbewegung des Düsenkegels mitmachen muß.The live steam goes in the = sense of the arrows from inlet i through the Live steam valve 7, the nozzle 2 and the nozzle core tip 9 after the outlet opening 3 of the mixture. The matt steam drawn in passes through the suction opening q. a, passes through the intake channels 5 and is entrained after the outlet opening 3 and brought back into the heating system. The nozzle cone 6 is with the valve cone 7 by means a nozzle core 8 connected so that it can only rotate around its own axis, but is forced to go along with all longitudinal movements of the valve cone. The nozzle core tip 9 forms the tip of the nozzle cone 6 and is connected to it so that they each Must participate in the longitudinal movement of the nozzle cone.
Bei kleinster öffnung des Frischdampfventils 7 sind die freien Querschnitte der Düse 2 sowie der Ansaugöffnung q. und der Ansaugkanäle 5 ebenfalls die kleinsten, während bei Vergrößerung der Ventilöffnung diese Querschnitte sich ebenfalls vergrößern. Das Absperrventil wird wie ein gewöhnliches Absperrventil mittels Handrad io betätigt.At the smallest opening of the main steam valve 7, the free cross-sections are the nozzle 2 and the suction opening q. and the intake ducts 5 are also the smallest, while when the valve opening is enlarged, these cross-sections also enlarge. The shut-off valve is operated like a normal shut-off valve using the io handwheel.
Um bei wechselnder Frischdampfzufuhr eine stets sichere und größtmögliche Saugwirkung zu erzielen, genügt es nicht, wie bei bekannten Dampfstrahlapparaten nur den Querschnitt der Strahldüse 2 mittels des Düsenkerns 8 zu verändern, ohne den Querschnitt der Ansaugkanäle zu verstellen. Es ist vielmehr, wie Versuche gezeigt haben, erforderlich, daß die Kanäle 5 der Ansaugdüse sowie die Saugöffnung q. im! Ansaugrohr gleichzeitig entsprechend verkleinert oder vergrößert werden. Weiter muß die Expansionsstelle des Dampfes stets die gleiche Lage zu den Ansaugdüsenkanälen 5 behalten. Das ist dadurch erreicht, daß die Düsenkernspitze 9, an der die Expansion erfolgt, mit dem die Ansaugdüsenkanäle begrenzenden Düsenkegel 6 fest verbunden ist.In order to ensure that the fresh steam supply is always safe and as large as possible It is not sufficient to achieve suction, as is the case with known steam jet devices only to change the cross section of the jet nozzle 2 by means of the nozzle core 8 without to adjust the cross-section of the intake ducts. Rather, it is shown as experiments have, required that the channels 5 of the suction nozzle and the suction opening q. in the! Suction pipe can be reduced or enlarged accordingly at the same time. Further the expansion point of the steam must always be in the same position in relation to the suction nozzle channels 5 keep. This is achieved in that the nozzle core tip 9, at which the expansion takes place, with the nozzle cone delimiting the intake nozzle channels 6 firmly connected is.
