Definitions

  • the invention relates to a blow-out device with a blow-out valve for the discharge and drain pipes of submarines for the discharge of weapons by means of compressed gas, which can be fed from assigned compressed gas containers and controlled via a circuit arrangement, an opening cross section for the compressed gas increasing depending on the stroke and the opening speed of the Blow-out valve can be changed by the outlet valve being controllable by a hydraulic control device consisting of a piston and a cylinder via a connecting element.
  • the object of the invention is to provide a simple design in a development of the known arrangements in order to enable a variable opening speed as a function of the piston stroke and to ensure a sufficiently constant ejection speed.
  • the tasks are solved according to the invention in that the cylinder spaces separated by the piston are connected to one another by several overflow connections, different overflow cross sections being released in succession depending on the piston stroke.
  • the hydraulic control valve makes it possible to control the speed as a function of the valve lift and to determine a desired course of the opening speed.
  • Embodiments and developments of the invention are characterized by the features of the subclaims.
  • the opening speed of the blow-out valve it is also possible for the opening speed of the blow-out valve to have an approximately constant low value in one part of the valve stroke, an approximately constant higher value over another part of the stroke and again a low value over a third part.
  • a blow-out valve 1 is arranged in a compressed gas bottle 2 and closes a bottle interior 3 from a blow-out cross-section 4 with the aid of a sealing element 5.
  • the blow-out valve 1 is connected via a piston rod 7 to a hydraulic piston 8 which is guided in a hydraulic cylinder 9.
  • the hydraulic cylinder 9 is closed by a base piece 10 and a cover 11.
  • the hydraulic fluid located on both sides of the cylinder is connected by an overflow channel 12, which contains a throttle element 13.
  • the blow-out valve 1 is held in the closed position in the idle state by a spring 14 and additionally secured in that compressed gas is stored in a space 15 behind the valve, which can overflow from the compressed gas space 3 via a small bore 16.
  • the space 15 behind the blow-out valve 1 is vented via a vent valve 17.
  • the compressed gas acting on the front is thus able to open the valve.
  • a pressure builds up in the hydraulic chamber 18, which allows the hydraulic fluid to flow into the hydraulic chamber 19 via the throttle 13 and the channel 12.
  • the opening speed of the valve is determined by the size of the throttle cross section at the throttle 13 and is relatively small.
  • the same effect is also achieved in that the cylinder 9 is provided with longitudinal grooves 23 of small cross-section, which are alternately replaced by longitudinal grooves 24 of large cross-section.
  • the length 25 of the longitudinal grooves 24 must be greater than the height 26 of the hydraulic piston 8.
  • the hydraulic piston 8 contains a calibrated bore 27, in which a caliber rod 28 slides.
  • This rod 28 has large diameters 29 alternating with smaller diameters 30, so that here too the piston 8 runs alternately through areas of small overflow cross section and large overflow cross section.
  • the bore 27 and the caliber 28 can be made so narrow in its cross-sectional parts 29 that the remaining annular gap is no longer effective for the overflow process.
  • an additional overflow channel 31 with a throttle element 32 must be arranged in the cylinder 9.
