Abstract

Bei einem Druckgasbehälter für Ausstoß- und Ablaufrohre von U-Booten ist zur Erfassung der Funktion des Ausblasventils und der Ausflußrate vorgesehen, den Druckabfall innerhalb des Druckgasbehälters heranzuziehen. Hierbei werden ein einstellbarer oberer und unterer Druckwert als Sollwerte vorgesehen und mit den Ist-Werten verglichen. Die Laufzeit zwischen den eingestellten Werten wird dabei über eine Laufzeitanzeige angezeigt. Es ist damit möglich, ohne größeren Aufwand den zeitlichen Verlauf des Massendurchsatzes zu erkennen.In the case of a pressurized gas container for the ejection and drain pipes of submarines, the function of the blow-off valve and the outflow rate is provided to use the pressure drop within the pressurized gas container. Here, an adjustable upper and lower pressure value are provided as setpoints and compared with the actual values. The runtime between the set values is shown on a runtime display. It is thus possible to recognize the time course of the mass throughput without great effort.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Erfassung der zeitlichen Druckgasabgabe aus Druckgasbehältern für Ausstoß- und Ablaufrohre von U-Booten, bei denen das Druckgas über ein systemgesteuertes Ausblasventil zuführbar ist.The invention relates to a device for recording the temporal discharge of pressurized gas from pressurized gas containers for ejection and drain pipes of submarines, in which the pressurized gas can be supplied via a system-controlled blow-out valve.

Bei derartigen Anordnungen hat das Ausblasventil neben der eigentlichen Öffnungsfunktion auch eine Steuerfunktion zu erfüllen, um die auszustoßenden Waffen bei allen Tauchtiefen mit vorgegebenen Geschwindigkeiten auszustoßen. Hierbei ist es somit erforderlich, die Durchsatzmengen und damit den Auslaßquerschnitt in Anpassung an die Tauchtiefe stark zu verändern sowie damit die Charakteristik der Druckgasabgabe zu wählen.In such arrangements, in addition to the actual opening function, the blow-out valve also has to perform a control function in order to eject the weapons to be ejected at predetermined speeds at all diving depths. It is therefore necessary to greatly change the throughput quantities and thus the outlet cross-section in order to adapt to the immersion depth, and thus to select the characteristic of the pressure gas discharge.

Eine Überprüfung und Messung des jeweils eingestellten Verlaufs der Druckgasabgabe aus dem Druckgasbehälter, insbesondere nach der Durchführung von Wartungsarbeiten, ist bisher nur mit aufwendigen Meßtechniken durchführbar und ist infolgedessen für eine schnelle Überprüfung im praktischen Betrieb wenig geeignet.A check and measurement of the respectively set course of the pressurized gas discharge from the pressurized gas container, in particular after carrying out maintenance work, has hitherto only been possible with complex measuring techniques and is therefore unsuitable for a quick check in practical operation.

Die Aufgabe der Erfindung ist es, auf einfache Weise für eine Anordnung der gattungsgemäßen Art eine Überprüfungs- bzw. Kontrollvorrichtung zu schaffen, die die Funktion des Ausblasventils und der Ausflußrate erkennen läßt.The object of the invention is to provide in a simple manner for an arrangement of the generic type, a checking or control device which reveals the function of the blow-out valve and the outflow rate.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß dadurch, daß der Druckgasbehälter einen Druckgeber mit einer Druckanzeige sowie einen Wandler zur Abgabe eines elektrischen Signals aufweist und ein oberer und unterer Druckwert an zugeordneten Gebern als Soll- werte in Form von elektrischen Signalen einstellbar sind, wobei das Signal des Ist-Wertes und jeweils ein Signal der eingestellten Soll-Werte getrennten Vergleichsstufen zugeführt werden und die Vergleichsstufen ein Zeitglied mit Laufzeitanzeige derart steuern, daß beim unterschreiten des eingestellten oberen Druckwertes das Zeitglied gestartet und beim Erreichen des unteren Druckwertes gestoppt wird.This object is achieved according to the invention in that the compressed gas container has a pressure transmitter with a pressure display and a converter for emitting an electrical signal and an upper and lower pressure value can be set on assigned sensors as setpoints in the form of electrical signals, the signal of the actual value and a signal of the setpoint values being supplied to separate comparison stages and the comparison stages control a timing element with runtime display in such a way that when it falls below of the set upper pressure value, the timer is started and stopped when the lower pressure value is reached.

Durch diese Anordnung ist es möglich, ohne größeren Aufwand den zeitlichen Verlauf des Massendurchsatzes zu erkennen, wobei der Druckabfall innerhalb des Druckgasbehälters herangezogen wird.This arrangement makes it possible to recognize the time course of the mass throughput without great effort, the pressure drop within the compressed gas container being used.

Weiterhin wird alternativ vorgeschlagen, daß der Sollwert für einen Stoppimpuls durch ein einstellbares Zeitglied gebildet ist.Furthermore, it is alternatively proposed that the setpoint for a stop pulse is formed by an adjustable timer.

In diesem Fall ist der ermittelte Druck in Verbindung mit den beiden eingestellten Sollwerten für das Zeitintervall und dem Druck, von dem aus das Zeitintervall gemessen wird, ein Maß für die Funktion des Auslaßventils und der Ausflußrate.In this case, the pressure determined in conjunction with the two set values for the time interval and the pressure from which the time interval is measured is a measure of the function of the exhaust valve and the outflow rate.

Eine günstige Meßstrecke wird dadurch gebildet, daß der obere Druckwert in einem Bereich oberhalb von 90 % und der untere Druckwert in einem Bereich von etwa 50 % bis 70 % des Fülldrucks des Druckgasbehälters liegt.A favorable measuring section is formed in that the upper pressure value is in a range above 90% and the lower pressure value is in a range of approximately 50% to 70% of the filling pressure of the compressed gas container.

In der Zeichnung sind Ausführungsbeispiele der Erfindung schematisch dargestellt. Es zeigen:

  • Figur 1 eine Schaltungsanordnung mit einer Sollwertbildung durch einen oberen und unteren Druckwert und
  • Figur 2 eine Schaltungsanordnung mit einer Sollwertbildung durch einen oberen Druckwert und ein einstellbares Zeitglied.
Exemplary embodiments of the invention are shown schematically in the drawing. Show it:
  • Figure 1 shows a circuit arrangement with a setpoint formation by an upper and lower pressure value and
  • Figure 2 shows a circuit arrangement with a setpoint formation by an upper pressure value and an adjustable timer.

Ein dargestellter Druckgasbehälter 1 besitzt einen Druckgeber 2, der über einen Wandler ein elektrisches Signal bildet. Ein Schaltkreis für ein systemgesteuertes Ausblasventil ist nicht mit dargestellt. Für einstellbare obere und untere Druckwerte sind Geber 5 und 6 angeordnet, die als Festwertgeber einen Sollwert als elektrisches Signal vorgeben. Das Signal der Geber 5 und 6 wird getrennten Vergleichsstufen 3 bzw. 4 zugeführt und mit dem vom Druckgeber 2 kommenden Signal als Ist-Wert verglichen. Unterschreitet der Druck im Druckgasbehälter 1 den eingestellten oberen Druckwert des Gebers 5, dann gibt die Vergleichsstufe 3 einen Startimpuls an ein Zeitglied 7. Wird nach einer bestimmten Zeit der eingestellte Druckwert des Festwertgebers 6 erreicht, gibt die Vergleichsstufe 4 einen Stoppimpuls auf das Zeitglied 7 und hält in diesem Fall gleichzeitig über einen Schalter 8 den zu dieser Zeit herrschenden Druck im Druckgasbehälter 1 fest. Dieser Druck wird an einer Anzeige 9 angezeigt, während die zugehörige Laufzeit an einer Anzeige 10 zu entnehmen ist. Die gewonnene Laufzeitanzeige stellt in Verbindung mit der Druckanzeige bzw. den eingestellten unteren Druckwert, ein Maß für die Ausflußrate aus dem Druckgasbehälter 1 dar und ermöglicht die Kontrolle des eingestellten Ausblasventils.A compressed gas container 1 shown has a pressure transmitter 2 which forms an electrical signal via a converter. A circuit for a system-controlled blow-out valve is not shown. For adjustable upper and lower pressure values, sensors 5 and 6 are arranged which, as fixed-value sensors, specify a setpoint as an electrical signal. The signal from the transmitters 5 and 6 is fed to separate comparison stages 3 and 4 and compared with the signal coming from the pressure transmitter 2 as the actual value. If the pressure in the compressed gas container 1 falls below the set upper pressure value of the transmitter 5, then the comparison stage 3 gives a start pulse to a timer 7. If the set pressure value of the fixed value transmitter 6 is reached after a certain time, the comparison stage 4 gives a stop pulse to the timer 7 and in this case simultaneously holds the pressure prevailing at that time in the compressed gas container 1 via a switch 8. This pressure is shown on a display 9, while the associated runtime can be seen on a display 10. The runtime display obtained, in conjunction with the pressure display or the set lower pressure value, is a measure of the outflow rate from the compressed gas container 1 and enables the control of the set blow-out valve.

Gemäß Figur 2 wird bei Überschreiten eines oberen Druckwertes über die Vergleichsstufe 3 ein einstellbares Zeitglied 11 in Betrieb gesetzt. Dieses Zeitglied 11 gibt nach Ablauf eines vorgegebenen ZeitIntervalls über den Schalter 8 ein Signal auf eine mit dem Speicherdruck mitlaufende Anzeige 9 für den Druck. Hierdurch wird der Druck an der Anzeige 9 zum Schaltzeitpunkt festgehalten. Der sich daraus ergebende Speicherdruck ist in Verbindung mit dem eingestellten Schalt-Intervall am Zeitglied 11 und dem Schaltdruck an der Vergleichsstufe 3 ein Maß für drei Durchflußraten und die Funktion des Auslaßventils.According to FIG. 2, an adjustable timer 11 is put into operation when an upper pressure value is exceeded via comparison stage 3. After a predetermined time interval, this timer 11 sends a signal via the switch 8 to a display 9 for the pressure which is running along with the storage pressure. As a result, the pressure is held on the display 9 at the time of switching. The resulting memory pressure is in connection with the set switching interval on the timing element 11 and the switching pressure at the comparison stage 3 a measure for three flow rates and the function of the exhaust valve.
