Bisher wurden die aus verzinntem oder verbleitem Blech bestehenden Gehäuse für trockene Gasmesser aus zwei Seitenteilen hergestellt, die miteinander durch zwei Längsnähte verlötet waren und an die oben und unten je ein Deckel angelötet wurde. In einer Aussparung des einen Seitenteiles wurde alsdann auch noch das Gehäuse für das Zählwerk eingesetzt und verlötet. EinSo far, the housings, made of tinned or leaded sheet metal, were used for dry gas knife made from two side panels that are joined together by two longitudinal seams were soldered and a lid was soldered to the top and bottom. In a recess of one side part Then the housing for the counter was also inserted and soldered. A
ίο derartiges Gasmessergehäuse hat infolge der großen Gesamtlänge seiner Lötnähte sehr große Neigung zum Undichtwerden, was dadurch noch erhöht wird, daß die Nähte sich an den scharfen Kanten des Gehäuses befinden. ίο such gas meter housing has as a result of large total length of its soldered seams, very great tendency to leak, which is the result it is further increased that the seams are on the sharp edges of the housing.
Im Gegensatz hierzu besteht das den Gegenstand der vorliegenden Erfindung bildende Gehäuse, wie die Zeichnung in Fig. 1 in Vorderansicht und in Fig. 2 im Schnitt nach der Linie A-B zeigt, nur aus zwei schalenartig hergestellten Blechstücken α und b, die nach Art einer Dose zusammengesteckt und durch eine ringsum laufende, endlose, event, gefalzte Naht c miteinander verbunden und verlötet sind. In die eine dieser Schalen b wird von außen nach innen eine Vertiefung d eingedrückt, welche als Rückwand des Gehäuses für das Zählwerk des Gasmessers dient, so daß ein besonderes Einlöten dieses kleinen Gehäuses nicht erforderlich ist. Dieses Eindrücken war bei den bisherigen Gasmessergehäusen nicht möglich, da am oberen Rande des durch einen besonderen Deckel abzuschließenden Gehäuses nicht genügend Blech zu diesem Zweck stehen blieb.In contrast to this, the housing forming the subject of the present invention, as the drawing in Fig. 1 shows in front view and in Fig. 2 in section along the line AB , consists only of two shell-like sheet metal pieces α and b, which are in the manner of a can plugged together and connected to one another and soldered by an all-round, endless, event, folded seam c. In one of these shells b a recess d is pressed from the outside in, which serves as the rear wall of the housing for the counter of the gas meter, so that special soldering of this small housing is not necessary. This indentation was not possible with the previous gas knife housings, because there was not enough sheet metal left for this purpose on the upper edge of the housing, which was to be closed by a special cover.
Durch die Wände der Vertiefung geht die Gasmesserwelle in bekannter Weise mittels einer Stopfbüchse e, und außen ist ebenfalls in bekannter Weise die Schutzkappe f für das Zählwerk aufgelötet. Die Ein- und Auslaßstutzen sind bei g und h angedeutet.The gas meter shaft passes through the walls of the recess in a known manner by means of a stuffing box e, and the protective cap f for the counter is also soldered on the outside in a known manner. The inlet and outlet ports are indicated at g and h.
Bei dieser Gestalt des Gasmessers können alle scharfen Ecken und Kanten vermieden werden, so daß seine Festigkeit gegen inneren Druck und auch gegen Stöße von außen im Verhältnis zu den bisher üblichen Gehäuseformen eine außerordentlich große ist.With this shape of the gas knife, all sharp corners and edges can be avoided so that its resistance to internal pressure and also to external impacts in the Relation to the housing shapes customary up to now is an extraordinarily large one.
