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, (gemäss einem nicht vorveröffentlichten Vorschlag nach der EP Nr. 0066734 A1).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 all speeds at predetermined speeds. It is therefore necessary to change the throughputs and thus the outlet cross-section to match the immersion depth, and to select the characteristic of the pressure gas discharge (according to a not previously published proposal according to EP No. 0066734 A1).

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 able to be carried out using complex measuring techniques and is consequently not very suitable 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 checking 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 Sollwerte in Form von elektrischen Signalen einstellbar sind, wobei das Signal des Istwertes und jeweils ein Signal der eingestellten Sollwerte 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 pressure 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 In each case, a signal of the setpoint values is fed to separate comparison stages and the comparison stages control a timer with a runtime display in such a way that the timer is started when the set upper pressure value is undershot and is 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 pressure gas container being used.

Weiterhin wird alternativ vorgeschlagen, dass der Druckgasbehälter einen Druckgeber mit einer Druckanzeige sowie einen Wandler zur Abgabe eines elektrischen Signals aufweist und ein oberer Druckwert an einem zugeordneten Geber als Sollwert in Form eines elektrischen Signals einstellbar ist, wobei das Signal des Istwertes und das Signal des eingestellten Sollwertes einer Vergleichsstufe zugeführt wird und ein einstellbares Zeitglied mit Laufzeitanzeige derart steuert, dass beim Unterschreiten des eingestellten oberen Druckwertes das Zeitglied gestartet und der Sollwert für einen unteren Druckwert durch einen Stoppimpuls des einstellbaren Zeitgliedes gebildet wird.Furthermore, it is alternatively proposed that the pressurized gas container has a pressure transmitter with a pressure display and a converter for emitting an electrical signal, and an upper pressure value can be set on an assigned transmitter as a setpoint in the form of an electrical signal, the signal of the actual value and the signal of the set value Setpoint is supplied to a comparison stage and controls an adjustable timer with runtime display in such a way that when the set upper pressure value is undershot, the timer starts and the setpoint for a lower pressure value is formed by a stop pulse of the 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 setpoint 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:

  • Fig. eine Schaltungsanordnung mit einer Sollwertbildung durch einen oberen und unteren Druckwert, und
  • Fig. 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:
  • Fig. A circuit arrangement with a setpoint formation by an upper and lower pressure value, and
  • Fig. 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 Istwert 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, dann 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 supplied 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 sends 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 sends a stop pulse to the timer 7 and in this case simultaneously holds the pressure in the compressed gas container 1 at that time 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 Fig. 2 wird bei Unterschreiten 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 Schaltintervall am Zeitglied 11 und dem Schaltdruck an der Vergleichsstufe 3 ein Mass für die Durchflussraten und die Funktion des Auslassventils.According to FIG. 2, an adjustable timer 11 is put into operation when the pressure falls below an upper value 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 accumulator pressure in conjunction with the set switching interval on the timing element 11 and the switching pressure on the comparison stage 3 is a measure of the flow rates and the function of the exhaust valve.
