Description

Vorrichtung zum Anzeigen, Registrieren und Zählen der Spitzenwerte des Verbrauchs strömender Medien Die Erfindung betrifft Vorrichtungen zum Anzeigen, Registrieren und Zählen der Spitzenwerte des Verbrauchs von in Rohrleitungen strömenden flüssigen oder gasförmigen Medien. Bekannte Vorrichtungen dieser Art haben als Strömungsmengenmesser eine durch die Strömung angehobene Stauscheibe, deren Ausschlag vermerkt wird, wenn er einen vorgeschriebenen Wert überschreitet. Um kurze Belastungszunahmen, sog. Belastungsstöße, auszuschalten, ist eine die Bewegung des Stellorgans der Anzeigevorrichtung stark dämpfende besondere Flüssigkeitsbremse vorgesehen.Device for displaying, registering and counting peak values the consumption of flowing media The invention relates to devices for displaying, Registering and counting the peak values of the consumption of flows in pipes liquid or gaseous media. Known devices of this type have a flow meter a baffle plate raised by the current, the deflection of which is noted when it exceeds a prescribed value. To avoid short increases in load, so-called. To switch off load surges is the movement of the actuator of the display device strong damping special liquid brake provided.

Erfindungsgemäß wird als Strömungsmesser einer der bekannten, aus Strömungswiderstand (Staurand, Düse, Venturirohr) und DifferentWmanometer bestehenden verwendet und die Dämpfung der Anzeigevorrichtung dadurch erzielt, daß entweder die Meßdruckleitungen entsprechend gedrosselt oder die zu beiden Seiten der beweglichen Wand (Membran, Glocke, Kolben) des Differentialmanometers liegenden Räume so ausgebildet werden, da:ß sie als Druckausgleicbsräume wirken. Auch können beide Maßnahmen gleichzeitig angewendet werden.According to the invention, the flow meter used is one of the known from Flow resistance (reservoir edge, nozzle, venturi tube) and differential pressure gauge existing used and the attenuation of the display device achieved in that either the measuring pressure lines throttled accordingly or those on both sides of the movable ones Wall (membrane, bell, piston) of the differential pressure gauge are designed in this way because: ß they act as pressure compensation spaces. You can also take both measures at the same time be applied.

Zwecks Ausgleichs der Druckdifferenz nach Absinken des Verbrauchs wird weiterhin erfindungsgemäß eine die Räume zu beiden Seiten der beweglichen Wand verbindende Leitung mit einstellbarem Querschnitt angeordnet.To compensate for the pressure difference after consumption has decreased is still according to the invention one of the spaces on both sides of the movable wall connecting line arranged with adjustable cross-section.

Die Zeichnungen zeigen im Längsschnitt (Abb. i) und in Aufsicht (Abb. 2) .ein für Gasverbrauchsleitungen bestimmtes Ausführungsbeispiel des Erfindungsgedankens mit einer Venturidüse als Druckdifferenzerzeuger.The drawings show in longitudinal section (Fig. I) and in plan view (Fig. 2). An embodiment of the inventive concept intended for gas consumption lines with a Venturi nozzle as a pressure difference generator.

Der Gasleitunga ist die Venturidüse b von entsprechender Bemessung eingefügt. Diese steht durch ihre Anzapfleitungen c und d mit dem Meßraum ein Verbindung, welcher durch die Querwand f und die in einem Ausschnitt derselben eingesetzte, als Druckanzeigeorgan dienende Membran g in zwei Kammern e1 und e2 unterteilt ist. Die der Zuführung des Unterdruckes dienende Leitung d hat eine einstellbare Drosselstelle h. Die Wand j ist mit einer als Querverbindung zwischen den Kammern dienenden Bohrung i versehen, deren Querschnitt durch die Einstellschraube k ebenfalls beliebig verringert werden kann. Die Membran g trägt sexzentrisch die übertragungsstange L und wird von der am oberen Ende der letzteren angreifenden Blattfeder m in der Nullage gehalten. Die Stange l überträgt die Membranausschläge über die Hebelübersetzung n auf den Klinkenhebel o. Die Zahnteilung des zugehörigen Zählwerkrades p ist so bemessen, daß ein Eingriff des Klinkenhebels nur bei entsprechend starkem Membranausschlag möglich ist. Da eine kurzfristige Unterdruckerzeugung in der Düse keine für einen solchen Ausschlag der Membran genügende Druckdifferenz zwischen ei und e2 auslöst, ist der Klinkenhub in diesem Falle zu kurz, um das Zählwerk zu schalten, und während sich die bestehende Differenz langsam ausgleicht, geht der Klinkenhebel o, ohne den nächsten Zahn des Zählwerkrades p gegriffen zu haben, wieder zurück. Durch Anordnung der Atmungsmembran g kann der Meßraum in Beziehung zum barometrischen Außendruck gesetzt werden.The venturi nozzle b of the appropriate size is inserted into the gas line a. This communicates with the measuring chamber through its tap lines c and d, which is subdivided into two chambers e1 and e2 by the transverse wall f and the diaphragm g which is inserted in a section of the same and serves as a pressure indicator element. The line d, which is used to supply the negative pressure, has an adjustable throttle point h. The wall j is provided with a bore i serving as a cross connection between the chambers, the cross section of which can also be reduced as desired by the adjusting screw k. The membrane g carries the transmission rod L in a sex-centric manner and is held in the zero position by the leaf spring m acting at the upper end of the latter. The rod l transmits the diaphragm deflections via the lever transmission n to the ratchet lever o. The tooth pitch of the associated counter wheel p is dimensioned so that the ratchet lever can only engage with a correspondingly strong diaphragm deflection. Since a short-term negative pressure generation in the nozzle does not trigger a pressure difference between ei and e2 that is sufficient for such a deflection of the membrane, the pawl stroke in this case is too short to switch the counter, and while the existing difference slowly balances out, the pawl lever o without having gripped the next tooth of the counter wheel p. By arranging the breathing membrane g, the measuring space can be related to the external barometric pressure.
