Definitions

  • the invention relates to tanks for any fluid such as gas, at a pressure of the order of 10 to 500 bars, liquid, volatile or flammable, or hydraulic fluid.
  • tanks made of composite materials composed of an internal envelope, ensuring fluid-tightness and made of molded synthetic materials, and of an external envelope, ensuring mechanical resistance and produced by resin reinforced by a winding. filamentary.
  • the ends of such reservoirs are mechanically reinforced by metal bases interposed between the two envelopes and of which that disposed on the side of the normally open end of the reservoir is provided with a portion in the form of a nozzle, equipped with means for connection to a source of fluid supply or fluid outlet control, see for example EP-A-0 300 931.
  • the practice shows, that in the event of a localized shock on one of the bases, as well as in the event of excessive external pressure on said base, as can happen with tanks for respiratory gases of plungers at great depth, the base can be pushed inside the tank causing the deterioration and even the rupture of the interior envelope, in the zone of this one bordering the periphery of the base.
  • Such an accident allows the fluid to escape from the interior envelope and to migrate between the latter and the exterior envelope which, because of its structure, can allow the escape of the fluid under pressure outside.
  • the object of the present invention is to remedy this by providing a protection device resistant to impact and to external pressures which is simple to implement and inexpensive.
  • the device comprises, on each nozzle of the reservoir, on the one hand, a frustoconical metal cup, of the same conicity as the base of the nozzle and of external diameter at least equal to that of this base. , this cup being integral with a threaded bushing aimed at a thread produced on the external part of the end piece, on the other hand, a frustoconical washer made of elastic material interposed between the cup and the external face of the end of the reservoir and , in addition, a lock nut screwed onto the end piece.
  • the cup absorbs all of the stresses and distributes them over its entire surface over the two tanks. This prevents any localization of the stresses and opposes any break in the connection between the internal and external envelopes of the reservoir, respectively, and therefore any deterioration of the latter.
  • the washer made of elastic material absorbs the tightening torque during assembly and, in the event of an impact, constitutes an additional protective shock absorber for the tank.
  • the protective cup also constitutes a support for marking by punching any indication concerning its structure, its content or its regulatory tests.
  • this generally cylindrical tank comprises an internal envelope 3 made for example of polyamide, polypropylene or polyethylene, and an external envelope 4 made, for example, of epoxy resin reinforced with glass fibers and obtained by filament winding.
  • This tank is equipped on the side of its closed end with a nozzle with bottom cup generally designated by 5, disposed between the two inner and outer envelopes and made of rigid material such as bronze, mechanical stainless steel, aluminum alloy or stainless steel.
  • a part 6 made of the same material as the cup 5 and comprising a tubular part 7 forming a neck.
  • the central bore 8 of this part is tapped at 9 to allow the connection of a tube, a regulator or a tap.
  • This part 6 also includes a cup 10 which, like that 5, is provided with an external face 13 which, intended to come into contact with the external envelope 4, is frustoconical.
  • Such a reservoir may also, as shown, on the right-hand side of the figure, comprise a coating 17 of fire and thermal protection, composed of two layers, namely an inner layer 18 constituted, for example, by a sheet of paper produced from ceramic fibers, and an outer layer 19 composed of a fire-resistant complex, glass fabric 20 - glass mat 21 assembled mechanically.
  • a coating 17 of fire and thermal protection composed of two layers, namely an inner layer 18 constituted, for example, by a sheet of paper produced from ceramic fibers, and an outer layer 19 composed of a fire-resistant complex, glass fabric 20 - glass mat 21 assembled mechanically.
  • each of the ends of the reservoir is reinforced by means disposed on each of its ends and comprising a metal cup 22, a washer 23 made of elastic material and a lock nut 24.
  • the metal cup 22 is integral with a socket 22a internally threaded and screwed onto a thread 25 produced outside the axial post of the corresponding end piece.
  • This cup is frustoconical and has the same taper as the bearing face 13 of the nozzle. Its outside diameter D is at least equal to the outside diameter of the corresponding nozzle.
  • the washer 23 is frustoconical and is made of rubber or any other plastic and compressible material. This washer absorbs the tightening torque of the cup 22, but also absorbs a large part of the shocks or forces applied to the cup 22, thereby protecting the external envelope 4 of the tank.
  • the cup 22 takes up all of the stress constraints, distributes them over the reservoir thanks to its large bearing surface and thus avoids any breakage of the connection of the external envelope 4 with the internal envelope 3 and of the internal envelope 3 with the corresponding base. In other words, this cup prevents any deterioration of the reservoir, either as a result of impact, or in the event of high external overpressure.
  • the lock nut holds the cup 22 perfectly in place, avoiding its unscrewing.
  • the right side of the figure shows that the protective cup can also be placed on the fire protection to ensure the same protection functions.
  • the cup also constitutes a marking support, by punching or other, for all indications concerning the tank, its content or its certification tests.
