Description
Auswechselbare Strömungsdrossel kleinster Weite für Meßzwecke In Apparaturen, die zu physikalischen oder technischen Untersuchungen dienen, tritt häufig das Bedürfnis auf, in dem an sich sehr engen Strömungswege einer Flüssigkeit oder eines Gases eine Drosselung von genau vorgeschriebener, oft nur nadelfeiner Lichtweite anzubringen. Diese Drosselung ist Selbstzweck, wenn es sich beispielsweise darum handelt, aus der Druckerhöhung hinter einem gedrosselten Meßgebläse fortlaufend das spezifische Gewicht eines Gases zu ermitteln. Auch der Schilling-Bunsen-Apparat wäre als Beispiel hier anzuführen. Die Drossel ist Mittel zum Zweck, wenn ihr Druckabfall, wie bei einem Staurand, dazu benutzt werden soll, um daraus auf die Durchflußmenge zu schließen. Das ist beispielsweisse in den als Strömungsteiler bekannten Einrichtungen der Fall.Exchangeable flow restrictor of the smallest size for measuring purposes in apparatus, which are used for physical or technical investigations, the need often arises on, in the very narrow flow paths of a liquid or a gas to apply a throttling of precisely prescribed, often only a needle-fine width. This throttling is an end in itself, for example when it comes to off the pressure increase behind a throttled measuring fan continuously the specific To determine the weight of a gas. The Schilling-Bunsen apparatus would also be an example to list here. The throttle is a means to an end when its pressure drop, as at a retaining edge, to be used to infer the flow rate from it. This is the case, for example, in the devices known as flow dividers.
Immer aber bringt die Kleinheit der Drosselöffnung die Gefahr einer Änderung ihrer meßtechnischen Eigenschaften dadurch mit sich, daß Staub oder anderweitige Niederschläge sich an ihr ansetzen. Daher besteht immer die Notwendigkeit, sie leicht zum Zweck der Reinigung herausnehmen zu können. Aus ähnlichen Gründen ist auch meistens eine leichte und billige Auswechselbarkeit wünschenswert. Reinigung und Auswechselung müssen vorgenommen werden können, ohne daß man die ganze Apparatur oder das betreffende Leitungsstück auseinanderzunehriien braucht.But always the small size of the throttle opening brings the danger of one Change in their metrological properties due to the fact that dust or other Precipitations settle on her. Hence there is always a need to do it easily can be removed for cleaning purposes. For similar reasons is also mostly easy and cheap interchangeability is desirable. Cleaning and replacement must be able to be carried out without having to use the entire apparatus or the relevant Pipe piece needs to be disassembled.
Gegenstand der Erfindung ist eine auswechselbare Drossel, die diesen Erfordernissen Genüge leistet. Im Leitungswege befindet sich die zweckmäßig in einem aus Gußmaterial hergestellten Teil befindliche Querbohrung i. In diese ist ein nach Abb. 2 gebogenes Blechstückchen eingesetzt, das die Drosselöffnung z enthält. Der Durchmesser dieses kleinen Blechzylinders ist so groß, daß man mit dem Finger in ihn hineinfassen und ihn so aus der Querbohrung herausheben oder in dieselbe wieder hineinsetzen kann. Das Blechstückchen legt sich federnd an die Wand der Querbohrung an. Nach dem Einsetzen wird die Querbohrung durch die Verschlußschraube 3 verschlossen.The invention is a replaceable throttle that this Satisfies requirements. In the conduction path, the is conveniently in one Part made of cast material located transverse bore i. In this is an after Fig. 2 bent piece of sheet metal used, which contains the throttle opening z. Of the The diameter of this small sheet metal cylinder is so large that you can put your finger in Grasp it in and lift it out of the transverse hole or into it again can put in. The piece of sheet metal lies resiliently against the wall of the transverse hole at. After insertion, the cross hole is closed by the screw plug 3.
Als Bohrung in einemBlech oder einerBlechfolie ist die Drosselöffnung sehr genau definiert und reproduzierbar. Bei nötig werdender Auswechselung ist ein neues Blechstückchen mit geringsten Mitteln und Kosten wieder herzustellen. In der Anordnung nach Abb. 3 ist die Drossel auch zur Anbringung in einem Leitungswinkel geeignet.The throttle opening is used as a hole in a sheet metal or sheet metal foil very precisely defined and reproducible. If a substitution becomes necessary, a to restore new pieces of sheet metal with minimal resources and costs. In the Arrangement according to Fig. 3, the throttle can also be installed in a conduit angle suitable.
