Description
lnAßdüse Gase und Dämpfe mit nur einem Einbauflansch. Die Erfindung bezieht sich auf .eine Meßdüse für Flüssigkeiten, Gase und Dämpfe, die in einen Einbauflansch eingesetzt ist und mittels dieses innerhalb der Rohrleitung gehalten wird. Das Neue besteht im wesentlichen darin, daß das Düsenrohr in dem Einbauflansch allein durch einen an seiner Eingangsstelle befindlichen kurzen, zylindrischen Teil gehalten wird, der mit den -Druckab-. nahmestellen versehen ist und in eine entsprechende Ausnehmung des Einbauflansches eingreift, wobei die Ausnehmung im Flansch in sonst bekannter Weise- so gestaltet ist, daß zugleich der übliche Ringraum für den Druckausgleich gebildet wird.Inlet nozzle for gases and vapors with only one mounting flange. The invention refers to .ein measuring nozzle for liquids, gases and vapors, which in a Installation flange is used and held by means of this within the pipeline will. What is new is essentially that the nozzle pipe is in the mounting flange solely through a short, cylindrical part located at its entry point is held with the -Druckab-. acceptance points is provided and in a corresponding Engages recess of the mounting flange, the recess in the flange in otherwise known way- is designed so that at the same time the usual annulus for pressure equalization is formed.
Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung im Längsschnitt dargestellt.In the drawing, an embodiment of the invention is in longitudinal section shown.
Das Düsenrohr a ist mit seinem Einlaufkonus in einen ringförmigen Einbauflansch b eingesetzt, der zwischen den Flanschen c der Leitungsrohre d .eingebaut ist. Das Düsenrohr a hat an seinem im Einbauflansch b liegenden Ende einen ringförmigen Ansatz e, der .auf seinen Umfange mit Löchern f versehen ist und einen im Einbauflansch b angeordneten Ringkanal g abdeckt. Dieser steht durch die Löcher/ mit dem Innenraum der Rohrleitung in Verbindung. Der Ansatz legt sich bei eingebauter Meßdüse gegen den einen Rohrflansch c, wodurch seine Lage im Einbauflansch gesichert ist. An der Einschnürungsstelle des Düsenrohrsa sind radiale Bohrungen k vorgesehen, welche die Düse mit einem Ringkanal m verbinden. Dieser Kanal steht mit einem im Einbauflansch b befindlichen Kanal n einer Anschlußbohrung o durch ein Rohr r in Verbindung.The nozzle tube a is inserted with its inlet cone into an annular installation flange b, which is installed between the flanges c of the line pipes d. At its end located in the installation flange b , the nozzle tube a has an annular extension e, which is provided with holes f on its circumference and covers an annular channel g arranged in the installation flange b. This is connected through the holes / with the interior of the pipeline. When the measuring nozzle is installed, the approach lies against one pipe flange c, whereby its position in the installation flange is secured. At the constriction point of the nozzle tube sa radial bores k are provided which connect the nozzle to an annular channel m. This channel is in connection with a channel n located in the mounting flange b of a connection bore o through a pipe r.
Das Düsenrohr a' besteht aus einem Stück mit dem den Auslaufkonus g bildenden Rohrteil. Letzterer wird zweckmäßig nur so lang gehalten, als für eine vorteilhafte Führung des strömenden Mittels im Bereich der größten Druckerholung erforderlich ist. Soll eine möglichst vollkommene Druckrückgewinnung erzielt werden, so kann an den Auslaufrohrkonus ein konisches Blechrohr s angesetzt werden.The nozzle tube a 'consists of one piece with the outlet cone g forming pipe part. The latter is expediently only kept as long as for one advantageous management of the flowing medium in the area of the greatest pressure recovery is required. If the most complete possible pressure recovery is to be achieved, a conical sheet metal pipe s can be attached to the outlet pipe cone.
