Definitions

  • the present invention relates to an aeration system of a compartment of a ship.
  • the invention relates to a ventilation system of the type comprising an air intake such a windsock, provided on the deck of the ship, above a ventilation opening in the compartment, arranged in this bridge, this orifice being provided with a valve mechanism comprising a valve seat, projecting above the deck and associated with a movable closure member thereof against the demand for elastic means between an open position of the valve mechanism, to allow ventilation of the compartment and a position of closure thereof, by a body of water entering the air intake, to prevent the passage of water in the compartment.
  • a ventilation system of the type comprising an air intake such a windsock, provided on the deck of the ship, above a ventilation opening in the compartment, arranged in this bridge, this orifice being provided with a valve mechanism comprising a valve seat, projecting above the deck and associated with a movable closure member thereof against the demand for elastic means between an open position of the valve mechanism, to allow ventilation of the compartment and a position of closure thereof, by a body of water entering the air intake, to prevent the passage of water in
  • the object of the invention is therefore to resolve these problems.
  • the invention relates to a system ventilating a compartment of a ship, of the type comprising an air intake provided on the deck of the ship, above a compartment ventilation opening in this bridge, this orifice being provided with a mechanism valve having a valve seat projecting above of the bridge and associated with a closure member thereof, movable against the request of means elastic, between an open position of the mechanism flap, to allow ventilation of the compartment and a closing position thereof, by a body of water penetrating the wind sock, to avoid the passage of water in the compartment, characterized in that the organ shutter includes temporary retention means of water provided with means for gradually draining it, to control the movement of this shutter member its closed position to its open position of the valve mechanism and in that the shutter member has a central dome-shaped portion extending above the valve seat and a peripheral portion in form of water retaining gutter extending around it valve seat, the lower part of which is provided with minus a water drain hole.
  • Such a ventilation system includes classic an air intake such as a windsock designated by the general reference 3, provided on the deck for example 4 of the ship, above a ventilation opening 5 of compartment 2 thereof, this ventilation opening 5 being spared in this bridge.
  • this orifice 5 is provided with a mechanism valve designated by general reference 6, comprising a valve seat 7 projecting above the deck and associated with a shutter body thereof designated by the reference general 8.
  • this shutter member 8 is movable against the solicitation of elastic means, designated by the general reference 9, between an open position of the valve mechanism 6 (Fig. 1) to allow ventilation of the compartment 2 and a closed position (Fig. 2) of this one, by a mass of water penetrating in the sleeve to air, to prevent the passage of water in the compartment.
  • the shutter member 8 comprises means 10 for temporary water retention provided with means 11 progressive emptying thereof, to control the displacement of this shutter member 8 from its position closing towards its open position of the mechanism valve 6.
  • this shutter member may for example comprise a portion control unit designated by the general reference 12, in the form of dome, extending above the valve seat 7 and a peripheral portion 13 in the form of a retaining gutter of water extending around this valve seat.
  • This gutter 13 for retaining water then constitutes the temporary retention means described therein previously.
  • the lower part of this portion device in the form of a water retaining gutter can have at least one drain hole, constituting the drain means 11 described above.
  • this peripheral portion of the organ shutter 8 may also include a rib peripheral designated by the general reference 14 on these figures, adapted to form, when the shutter member 8 is in the closed position of the valve mechanism, in cooperation with deck 4 of the ship, means of braking of the passage of water between this shutter member and the valve seat.
  • the organ shutter 8 is also requested by means elastic.
  • These means have been designated by the reference general 9 in these figures and may for example include a helical spring arranged in the extension of a sleeve 15, provided in the center of the valve mechanism.
  • This sleeve is adapted to receive, for example, a operation 16 of the shutter member 8 to allow a user to control its position and place it for example in a stable position for closing the flap mechanism.
  • these maneuvering means include example a rod 16a having at a first end an operating handle 16b by the user and connected to its other end, for example in 16c, to the organ shutter.
  • Means for blocking this shutter member in closing position of the valve mechanism are associated with the rod or the handle, in a conventional manner.
  • the central dome-shaped portion 12 of this obturation member 8 makes it possible to direct them in direction of the temporary retention means 10 thereof, this water then being discharged through the holes of emptying 11 of this obturation member and of the holes emptying the air bag, one of which is designated by the general reference la in this figure.
  • the mass water can then be evacuated from the air bag by the drain holes therefrom, the shutter member 8 remaining in the closed position of the valve mechanism, made the weight of the water retained in the retaining means of it.
  • the retained water in these ways can drain through the or each drain hole 11 of these, towards the holes of emptying the air bag and this, gradually, to allow, as can be seen in Figure 4, the progressive ascent of the shutter member 8 towards its flap mechanism open position, to allow ventilation of compartment 2 of the ship again.
  • the means for retaining water from the obturation member extend to a level at most equal to that of the seat of valve, which avoids any passage of water in the compartment during movement of the shutter member towards its open position.
  • the ventilation system according to the invention has a number of advantages by compared to conventional systems of the state of the art, insofar as the temporary water retention means to progressive emptying of the shutter member thereof allow to control the movements of this organ shutter from its closed position to its position opening of the flap mechanism, in order to avoid any passage of water through the opening in the bridge of the ship by not authorizing the movement of this organ towards its open position only when the windsock is sufficiently drained.
