Description

Schiebersteuerung für trockene Gasmesser Die Steuerungsorgane .für trockene Gasi-nesser werden, soweit sie, wie z. B. bei Schiebersteuerungen, Gleitflächen aufweisen, hauptsächlich aus Metall hergestellt. Es ist aber auch bereits vorgeschlagen worden, für den Schieber Glas zu verwenden, das wegen seiner Härte und seines Widerstandes gegen chemische Beanspruchungen als Baumaterial besonders günstig ist.Slide control for dry gas meters The control organs .for dry Gasi-nessers, as far as they, such. B. with slide controls, sliding surfaces mainly made of metal. But it has already been proposed been to use glass for the slide because of its hardness and resistance is particularly favorable as a building material against chemical stresses.

Wenn man nicht nur den Schieber, sondern auch den Schiebemost aus Glas herstellt, dann ist, insbesondere wenn man eine Schmierung der aufeinandergleitenden Teile zu vermeiden wünscht, dafür Sorge zu tragen, daß die Reibung der beiden Teile möglichst gering wird. Zu diesem Zweck wird erfindungsgemäß den beiden Gleitflächen ein Schliff von ungleicher Körnung gegeben. Die reibungsverringernde Wirkung dieser Maßnahme wird noch vergrößert, wenn man außer dem ungleich geköniten Schliff für Schieher und Rost Glasschmelzen verschiedener Härte verwendet. Abschlußorgane, bei denen die aufeinandergleitenden Teile aus Glasschmelzen verschiedener Härte bestehen, sind an sich bereits bekannt, und ihre Verwendung allein für Steuerungen von trockenen Gasmessern ist ebensowenig wie die Verwendung von Glas schlechthin als Material für den Schieberrost Gegenstand der Erfindung.If you not only turn off the slider, but also the sliding must Glass produces, then is, especially if you have a lubrication of the sliding on each other To avoid parts desires to take care of the friction of the two parts is as low as possible. For this purpose, according to the invention, the two sliding surfaces given a cut of unequal grain. The friction-reducing effect of this Measure is still magnified if one except for the unequal cut for Schieher and rust glass melts of different hardness are used. Closing organs, at which the parts sliding on each other consist of glass melts of different hardness, are already known per se, and their use only for controls of dry Gas meters is just as little as the use of glass as a material for the sliding grate object of the invention.

In der zugehörigen Abbildung ist ein Gleitrost a dargestellt, welcher aus Glas besteht und mit seinen drei Öffnungen die drei Kanalmündungen b, c, d, welche aus Metall bestehen, abschließt. Die luftdichte Verbindung zwischen Metall und Glasrost ist hergestellt, indem der Glasrost .eine Nute auf seiner unteren Fläche hat, welche mit passendem Kitt ausgeschmiert wird. In diesen Kitt werden dann die aufrecht ,gestellten Ränder der Kanäle hineingedrückt, so daß nach dem Erhärten des Kittes eine haltbare und luftdichte Verbindung besteht.The associated figure shows a sliding grate a, which is made of glass and with its three openings closes off the three channel openings b, c, d, which are made of metal. The airtight connection between metal and glass grate is made by the glass grate having a groove on its lower surface, which is smeared with suitable putty. The upright edges of the channels are then pressed into this putty, so that after the putty has hardened, a durable and airtight connection exists.
