Definitions

  • the invention relates to a device for purging air from closed containers. waterproof subject to uncontrolled tilting movements and intended to be filled with a fluid.
  • the submarine torpedo tubes are containers of this type: filled with air after insertion of a weapon, they must be filled with water before its launch. This filling is carried out with water on the one hand in order to facilitate the balancing operations before opening the exterior door and not influencing on the balance of the building, on the other hand due to the constraints of discretion to opening the front door. It is necessary, during this filling, to purge the air initially contained in the tube in order to limit the volume of air residual in the tube. Due to the length of the tubes and the movements plate of the submarine, correct filling of the tube with water requires double air purge intake, at the front and rear of the tube.
  • Torpedo tube installations typically use, before join a common circuit, two independent purge circuits, connected respectively to the front socket and the rear socket, and each composed of a tube crossing, motorized valves and a water presence detector.
  • the water presence detector controls the closing of the drain concerned when it detects a significant water flow indicating that the water level at the inside of the tube reaches the purge socket. Filling is deemed completed when both purge circuits are closed.
  • the device described in patent FR 2 699 643 uses, in its production base, a valve to close one of the purge sockets to guarantee a adequate filling of the tube whatever its inclination.
  • This type of device however has a number of drawbacks.
  • its footprint in the vertical plane is relatively large, which can be not compatible with certain torpedo tube architectures, in particular with "single-diameter" tubes for which the internal diameter of the tube is very close to the diameter of the weapon, or cause significant additional costs.
  • the environment inside the tube is particularly difficult medium very corrosive linked to immersion cycles, violent hydrodynamic phenomena during infills and gunfire, etc. Float valve devices may, under these conditions and due to the principle used, present reliability issues that would result in an inability to purge the tube correctly.
  • the invention aims to provide an air purge device allowing a correct filling of the tube regardless of its inclination, which is of design simple, and which does not use a mechanical device of the valve type for shut off an air purge intake.
  • the object of the invention is to propose a device for purging air in a tightly closed container subjected to movements, in particular of the type uncontrolled oscillatory with at least two air purge connections connected to a manifold, characterized in that it comprises as many air purge pipes as there are air purge intakes, each purge pipe being associated with a purge intakes and having a path such that it passes close to all the other sockets purge.
  • This device eliminates all materials related to a purge outlet. It thus makes it possible to significantly limit costs while conserving and even increasing the reliability of existing devices.
  • the drain pipes are inside the container.
  • the position of the collector is independent of the position of the sockets purge.
  • the manifold is located below the purge outlets.
  • the drain pipes can be equipped with tanks at each elbow.
  • Figure 1 shows the air purge device according to the invention for a torpedo tube filling application with two air purge intakes 4 and 5, the first at the front, the second at the rear.
  • Purge pipes 1 and 2 run inside the tube 3. For applications other than those concerning torpedo tubes they could be placed outside the container.
  • the principle is to run the pipe 1 linked to the front purge socket 4 to the level of the rear purge socket 5 and then make it join the purge manifold 6.
  • the rest of the circuit consists of motorized valves and a water presence detector.
  • the pipe 2 linked to the rear purge 5 travels as to it up to the level of the front purge socket 4 and also joins the manifold 6.
  • drain pipes are shown in a plan vertical but in reality they can be located in the same horizontal plane.
  • the air purge device ensures whatever the attitude of the tube and the pitching movements of the latter, the air purge complete tube during water filling, with closure automatic front or rear purge taps as appropriate, without the need for no mechanical valve type system.
  • the system may have a slight drawback with regard to noise in operation. It may indeed happen that during a change of plate, the drain hose that was partially filled with water does not have time to drain or cannot drain if the pipe that goes to the other outlet is partially installed lower than the purge socket (what we avoid doing when making the device). Once the purge is taken cleared, the pipe then contains a remainder of water which intermittently closes the pipe until the water, pushed by the au due to the pressure increase at inside the tube, has passed the elbow and allows air to escape, before possibly reforming a new residue; this generates noises of flow. This phenomenon should not however be considered with too much of importance.
  • the operation of the device is independent of the positioning of the purge manifold 6; some embodiments may nevertheless be more favorable than others as mentioned above.
  • the air purge device according to the invention can be generalized to a any number of purge outlets.
  • the complexity of the circuit increases nevertheless quickly with the number of takes.
  • figure 4 gives, in top view, an embodiment of a purge circuit for a parallelepiped tank with four air purge intakes 7, 8, 9, 10 connected to the collector 6.
  • the air purge device can find applications in the drain of any tank requiring several purge taps: tank of ballast, compensation boxes, etc ...
