Description
Schauglasfassung für Flüssigkeitsstandanzeiger 0. dgl. Uni unter Druck von Flüssigkeiten oder Gasen stehende Räume einsehen zu können, verwendet die Industrie Schaugläser, welche in Metallfassungen ab-cdichtet werden und die betreffenden Räume von anderen Räumen trennen. Die Abdichtung wurde bei allen bisher üblichen Formen in der Art erzielt, daß Packungen (Dichtungsringe) D auf die ebene oder konische Glasfläche aufgelegt wurden, wie dies die Abb. i: bis 3 zeigen. Alle diese bisherigen Ausführungsformen haben den Nachteil, daß durch das Zusarnmenp.-essen des Dichtungsmaterials infolge des Druckes die Schaugläser nach mehr oder weniger kurzer Betriebsdauer locker und undicht werden, so daß ein zeitweiliges Nachziehen der Klemmmuttern K nötig wird. Sehr oft muß auch das Dichtungsmaterial, ohne daß es chemisch verdorben ist, nachgepackt oder ersetzt werden.Sight glass socket for liquid level indicator 0. Like. Uni to be able to see rooms under pressure from liquids or gases, the industry uses sight glasses, which are sealed in metal frames and separate the rooms concerned from other rooms. The sealing was achieved in all forms customary up to now in such a way that packings (sealing rings) D were placed on the flat or conical glass surface, as shown in Figs. I: to 3 . All of these previous embodiments have the disadvantage that, due to the compression of the sealing material, the sight glasses become loose and leaky after a more or less short period of operation, so that the clamping nuts K have to be retightened from time to time. Very often the sealing material has to be repacked or replaced without it being chemically spoiled.
Sind die Schaugläser unzugänglich, so stößt das Nachziehen der Klemmuttern auf Schwierige keiten und gibt zu Betriebsstörungen Anlaß. Bei wechselndem Druck, bei welchem das Schauglas einmal auf der einen und einmal auf der anderen Seite gegen Druck dichten soll, treten die Betriebsstörungen wegen Undichtigkeit am häufigsten auf.If the sight glasses are inaccessible, tightening of the lock nuts occurs to difficulties and gives rise to operational disruptions. With changing pressure, in which the sight glass is once on one side and once on the other side If you want to seal against pressure, malfunctions due to leaks occur most frequently on.
Der Gegenstand der Erfindung ist daher eine Schauglasfassung, welche diese Nachteile nicht be3itzt. Im wesentlichen besteht das Neue an der Bauart in der Form der den einzigen Dichtungsring pressenden Flächen des Schauglases und der Fassung. In den Abb. 4 bis 8 sind prinzipielle Ausführungsformen solcher Schauglasverschraubungen dargestellt. Die Flächen F, des Glases und Ff der Fassung pressen beim Einmontieren des Glases die DichtungsmasseD so zusammen, daß ihre Querschnittslinie einen Doppelkeil darstellt, wodurch unter dem Einflusse des Druckes, gleichgültig von welcher Seite der Verschraubung er auftritt, das Dichtungsmaterial nur immer fester in die Keilwinkel a zusammei gepackt wird. Durch diese Formgebung der dichtenden Preßflächen lockert sich das Schauglas nie, da durch das Festerpacken der Dichtungen die Keilwirkung das Glas in achsialer Richtung gegen den Preßring stets fester klemmt. Hierdurch wird das Nachziehen während des Betriebes vermieden. Ein Auswechseln des Dichtuligsmaterials wird nur dann notwendig, wenn die chemischen Einflüsse es zerstört haben.The object of the invention is therefore a sight glass holder which does not have these disadvantages. Essentially, the novelty of the design consists in the shape of the surfaces of the sight glass and the socket pressing the single sealing ring. In Figs. 4 to 8 basic embodiments of such sight glass screw connections are shown. When the glass is installed, the surfaces F, of the glass and Ff of the frame compress the sealing compound D so that their cross-sectional line represents a double wedge, whereby under the influence of the pressure, no matter from which side of the screw connection it occurs, the sealing material only becomes tighter and tighter Wedge angle a is packed together. Due to this shape of the sealing pressing surfaces, the sight glass never loosens because the tight packing of the seals means that the wedge effect always clamps the glass more tightly in the axial direction against the pressing ring. This avoids retightening during operation. A replacement of the sealing material is only necessary if the chemical influences have destroyed it.
DieQuerschnittslinienderdichtendenFlächen des Glases und der Fassung können beliebig geformt werden, wie dies beispielsweise die Abb. 4 bis 8 andeuten, wenn nur die beschriebene Doppelkeilform des für das Dichtungsmaterial bestimmten Raumes erreicht wird.The cross-sectional lines of the sealing surfaces of the glass and the frame can be shaped as desired, as shown, for example, in Figs. 4 to 8 , if only the double wedge shape of the space intended for the sealing material is achieved.
