Definitions

  • 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.
  • the blow-out valve 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the setpoint for a stop pulse is formed by an adjustable timer.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
