Description

Bisher hat man zum Einsetzen und Abdichten von gläsernen Schaurohren in mit Bohrungen oder Schlitzen versehenen äußeren Schutzrohren, z. B. solchen aus Stahl, Ringe und Cberwurfmuttern mit zwischengelegten Dichtungsringen benutzt. Beim Einsetzen der Röhre war hierbei ein genaues Ausrichten des Glasrohres in den Flanschen des Schutzrohres erforderlich, da andernfalls beim Festziehen das Glasrohr leicht springt.So far, one has to insert and seal glass viewing tubes in outer protective tubes provided with bores or slots, e.g. B. such from Steel, rings and union nuts used with sealing rings in between. At the Insertion of the tube was a precise alignment of the glass tube in the flanges of the protective tube is necessary, otherwise the glass tube will be lightly when tightened jumps.

Die Erfindung betrifft ein Verfahren zum Einsetzen und Abdichten von gläsernen Schaurohren in die äußeren Schutzrohre. Sie besteht darin, daß das Glasrohr durch eine Kittschicht mit dem Außenrohr verbunden wird. Durch diese Verbindungsart wird nicht nur eine völlig sichere Abdichtung nach außen hin erreicht, sondern auch einem Springen des Glases beim Einsetzen und späterhin Auftreten höherer Innendrücke vorgebeugt.The invention relates to a method for inserting and sealing glass viewing tubes into the outer protective tubes. It consists in the fact that the glass tube is connected to the outer pipe by a layer of cement. Through this type of connection a completely secure seal to the outside is not only achieved, but also cracking of the glass on insertion and later occurrence of higher internal pressures bent forward.

Um ein genaues zentrisches Einsetzen des Schaurohres in das äußere Schutzrohr zu erreichen, kann es zweckmäßig sein, zuvor eine Schnur oder einen Ring aus Asbest, Pappe o. dgl. zwischen zu legen. Zur besseren Haftung des Kittes am Glase kann ferner die Anbringung einer Anstrichschicht empfehlenswert sein.In order to ensure that the viewing tube is precisely inserted in the center of the outer To reach the protective tube, it may be useful to use a cord or ring beforehand made of asbestos, cardboard or the like. For better adhesion of the putty to the Furthermore, the application of a layer of paint can be recommended.

In der Zeichnung ist die Abdichtung eines Glasrohres für einen Durchflußmesser zur Erläuterung der Erfindung schematisch dargestellt. i ist hierbei (las gläserne Innenrohr, 2 das stählerne Außenrohr mit zwei Flanschen 3. q. ist ein Ring aus Asbestschnur, 5 der Schauschlitz des Stahlrohres, 6 eine Skala daran. 7 ist eine auf dem Innenrohr angebrachte Anstrichschicht, z. B. aus haltbarem Phenolformaldehydharz, und 8 die zum Einkitten und Abdichtung dienende Kittschicht, die über die Flansche 3 hinausragt und mit dem Glasrohr ab- schneidet. Die Kittschicht besteht beispielsweise aus in der Kälte selbst erhärtenden Phenolformaldehydharzen; es können jedoch auch Wasserglaskitte oder Blei- glätte, Glyceringlätte oder selbst beliebige andere Kitte verwendet werden, sofern ihre mechanische, chemische und thermische Widerstandsfähigkeit den jeweiligen Beanspruchungen entspricht. 9 ist ein in dem Schaurohr I)ewe"licliei- Schwimmer. Beim Einsetzen des inneren Glasrohres in das äußere Schutzrohr kann es sich empfehlen, an den Stellen, an denen das Glas nicht mit Kitt in Be- rührung kommt, d. h. also unter der zur Beobach- tung dienenden Schlitzung des Außenrohres, das Glas durch vorübergehendes :\ufklel)eti von Papier vor Anätzungen durch den Kitt oder den Anstrich zu schützen. Dieses Papier wird dann nach Er- härtung des Kittes wieder entfernt. In the drawing, the seal of a glass tube for a flow meter is shown schematically to explain the invention. i is here (the glass inner tube, 2 the steel outer tube with two flanges 3.q. is a ring made of asbestos cord, 5 the viewing slot of the steel tube, 6 a scale on it. 7 is a layer of paint applied to the inner tube, e.g. from durable phenol-formaldehyde resin, and 8 the putty layer used for cementing and sealing over the Flange 3 protrudes and with the glass tube cuts. The cement layer consists, for example, of in the Cold self-hardening phenol-formaldehyde resins; however, water glass cement or lead smoothness, glycerine smoothness, or even any other Putties are used provided their mechanical, chemical and thermal resistance den corresponds to the respective stresses. 9 is a in the viewing tube I) ewe "licliei- Swimmer. When inserting the inner glass tube into the outer protective tube can be recommended to the Places where the glass is not in contact with putty touch comes, that is, under the observation Serving slitting of the outer tube, the Glass through passing: \ ufklel) eti of paper from etching by the putty or the paint to protect. This paper is then hardening of the putty removed again.
