Description

  

  Trockener Gasmesser.    Gegenstand der Erfindung ist ein trockener  Gasmesser mit geteilten     Messkästen    und darin  angeordneten, um eine Achse hin- und her  schwingenden Membranen, bei welchem in  jedem     Messkasten    die zur Übertragung der       Membranbewegung    auf den Steuermechanis  mus dienende Fahnenachse in die Teilebene  des     Messkastens    und aus dessen für die  Schwingung der Membran in Betracht kom  menden Hohlraum heraus verlegt ist und die  Kastenwände nach innen der natürlichen Bie  gung der Membran entsprechend gerundet  sind, zum Zwecke, die toten Räume in den       Messkästen    tunlichst zu verringern.  



  Die beiliegende Zeichnung veranschaulicht  ein Ausführungsbeispiel des Erfindungsgegen  standes.  



       Fig.    1 ist eine Stirnansicht, teilweise ein  Schnitt desselben;       Fig.    2 ist ein senkrechter Querschnitt  nach Linie     I-II    von     Fig.    1;       Fig.    3 ist ein     wagrechter    Schnitt nach  Linie     III-IV    von     Fig.    1;       Fig.    4 veranschaulicht eine Einzelheit im  Schnitt nach Linie     V-VI    vom     Fig.    1.

      Im     Messgehäuse    4, dessen äussere Form  von der. üblichen durch die     kuppelförmige          Rundung    seiner Decke abweicht, sind die  beiden     Messkästen        B,    C untergebracht, die  nach einer Querebene hälftig geteilt sind und  in an sich bekannter Weise die hin- und her  schwingende Ledermembran     a    enthalten,  welche mit ihren Rändern zwischen die Rän  der der Kastenhälften eingeklemmt ist. In  ihrem Mittelteil sind die Ledermembranen     a     durch Blechscheiben b versteift, an denen die  sog.

   Fahnen c     angelenkt    sind, welche die  Schwingbewegung der Membranen auf je eine  zur Bewegung des     Steuermechanisxrius    die  nende Fahnenachse d übertragen. Während  nun bisher diese Fahnenachse im Hohlraum  des Kastens nach der Seite hin angeordnet  ist und auf diese Weise durch eigene Raum  beanspruchung sowohl, als auch durch un  gleichmässige     Faltenlegung    der Ledermem  bran notwendigerweise zur Bildung.

   von toten  Räumen Anlass gibt, ist sie bei der vorlie  genden Ausführungsform in die Teilebene  des     Messkastens    und aus dessen für die  Schwingung der Ledermembran in Betracht       kommenden    Hohlraum heraus verlegt, wie      dies aus     Fig.    3 deutlich zu ersehen ist, und  dabei bis auf die Stelle, wo die Fahne c mit  ihr verbunden ist, von einer Schutzhülse f  umgeben, welche verhindern soll, dass die  über die Fahnenachse hinweggehende Leder  membran durch Reibung beschädigt werde.

    Durch diese Anordnung der Fahnenachsen     d     kommen die     Ledermembranen    .der     Messkästen     sowohl in der einen wie in der andern End  stellung in genau gleicher Weise zur     Anlage     an die Seitenwände der     Messkästen,    und die  Volumina der     Messkästen    werden dadurch in  folge der Ausscheidung von toten Räumen in  beiden Fällen genau gleich.

   Eine weitere Ver  minderung     dertotenRäumeistdadurcherreicht,          dassdieKastenwändenach    innen der natürlichen  Biegung der     Alembran    entsprechend gerundet  sind, so dass die sonst üblichen scharfen  Winkel, wie solcher in     Fig.    4 durch strich  punktierte Linien     angedeutet    ist, in Wegfall  kommen. Die Verminderung der toten Räume  bewirkt, dass der Gasmesser bei verschieden  artigen, auch bei Überbelastungen gleich gut  läuft und in engen Fehlergrenzen anzeigt.  



  Um ein Festsaugen der     Ledermembranen     an den     Kastenseitenwänden    zu verhüten, sind  in diese Wände     kreuz    und quer kleine Ril  len     g    eingeprägt, jedoch so kleine, dass die  Membranen sich nicht     hineinsaugen    können.  



  Statt, wie üblich, den Ein- und     Auslass     für das Gas an den Seiten des Gasmesser  gehäuses vorspringend anzuordnen, ist hier  an der Decke des Gehäuses, deren     kuppel-          förmige    Rundung ihr eine gewisse Verstei  fung verleiht, ein     T-förmiger    Hohlkörper     h     angebracht, in dem der Ein- und     Auslass    für  das Gas durch eine Scheidewand i, die auch  die mit dem Steuermechanismus verbundene       Gaskammer    k unterteilt, voneinander getrennt  sind.

   Die     Anschlussstutzen    des Hohlkörpers     h     sind     wagrecht    gestellt, und durch Einschal  tung mehr oder weniger langer Bohrnippel     u       kann die     Anschlussweite    in beliebigen Grenzen  verändert werden, so dass der     Gasmesser    an  jede Rohrleitung     anschliessbar    ist.  



  Am obern Ende der     Messkästen    D, C ist  die übliche Schiebesteuerung D angeordnet.  Von derselben führen zu den     Messkamrnern     die     Gasein-    und Ausgangsrohre o. Das       Schiebergehäuse        s    mit dem Rost     r    ist     mit-          telst    einer einzigen Schraube     p        (Fig.    2) und  eines Quersteges     q    in dichter Verbindung  mit jenen Rohren o gehalten.



  Dry gas meter. The subject of the invention is a dry gas meter with divided measuring boxes and arranged therein, about an axis oscillating diaphragms, in which in each measuring box the flag axis serving to transmit the membrane movement to the control mechanism in the partial plane of the measuring box and from its for the Vibration of the membrane into consideration coming cavity is moved out and the box walls are rounded inwards to the natural bending of the membrane accordingly, for the purpose of reducing the dead spaces in the measuring boxes as much as possible.



  The accompanying drawing illustrates an embodiment of the subject matter of the invention.



       Fig. 1 is an end view, partly in section, of the same; Fig. 2 is a vertical cross section taken along line I-II of Fig. 1; Fig. 3 is a horizontal section on the line III-IV of Fig. 1; FIG. 4 illustrates a detail in section along line V-VI from FIG. 1.

      In the measuring housing 4, the outer shape of the. usual differs by the dome-shaped rounding of its ceiling, the two measuring boxes B, C are housed, which are divided in half according to a transverse plane and contain in a known manner the leather membrane a swinging back and forth, which with its edges between the edges of the Box halves is clamped. In their middle part, the leather membranes a are stiffened by sheet metal discs b, on which the so-called.

   Flags c are articulated, which transmit the oscillating movement of the membranes to one for each movement of the control mechanism, the flag axis d. While so far this flag axis is arranged in the cavity of the box to the side and in this way claims both by its own space, as well as by uneven folding of the Ledermem bran necessary for formation.

   of dead spaces gives rise to, it is in the present embodiment in the partial plane of the measuring box and out of its cavity that is considered for the vibration of the leather membrane, as can be clearly seen from Fig. 3, and up to the point , where the flag c is connected to it, surrounded by a protective sleeve f, which is intended to prevent the leather membrane extending over the flag axis from being damaged by friction.

    Due to this arrangement of the flag axes d, the leather membranes of the measuring boxes come to rest in exactly the same way on the side walls of the measuring boxes in both one and the other end position, and the volumes of the measuring boxes are thereby due to the elimination of dead spaces in both Cases exactly the same.

   A further reduction in the dead spaces is achieved by the fact that the box walls are rounded inwards according to the natural curvature of the membrane, so that the otherwise usual sharp angles, such as those indicated in Fig. 4 by dashed-dotted lines, are eliminated. The reduction of the dead spaces means that the gas meter runs equally well with different types, even with overloads, and displays within narrow error limits.



  In order to prevent the leather membranes from sticking to the side walls of the box, small grooves are criss-crossed in these walls, but so small that the membranes cannot suck themselves into them.



  Instead of arranging the inlet and outlet for the gas protruding on the sides of the gas meter housing, as usual, a T-shaped hollow body h is attached to the ceiling of the housing, the dome-shaped rounding of which gives it a certain stiffening, in which the inlet and outlet for the gas are separated from one another by a partition i, which also divides the gas chamber k connected to the control mechanism.

   The connecting pieces of the hollow body h are placed horizontally, and by switching on more or less long drilling nipples u, the connection width can be changed within any limits, so that the gas meter can be connected to any pipeline.



  The usual slide control D is arranged at the upper end of the measuring boxes D, C. The gas inlet and outlet pipes o lead from this to the measuring chambers. The valve housing s with the grate r is held in tight connection with those pipes o by means of a single screw p (FIG. 2) and a crosspiece q.
