Definitions

  • the present invention relates to a protective container with a fluid-tight seal for the underground installation of tanks containing pressurized liquefied gas, as for instance is known from FR-A-748 880.
  • the invention also relates to underground installations obtained by the use of protective containers of this type with fluid-tight seals.
  • tanks containing pressurized liquefied gas are usually installed above ground close to the places where the gas is to be used, which may be factories, restaurants or private houses.
  • the object of the present invention is to overcome the above disadvantages and to allow tanks containing pressurized liquefied gas to be installed underground such that they occupy as small a space as possible, in accordance with the dimensions of the tank, which can easily be concealed, in such a way that the aesthetic aspects of the installation location can also be satisfied and a greater level of safety and control of the operating conditions of the tank can be ensured as can the easy supplying of the tank.
  • a container of this type which is preferably made of plastics material, although the use of metal or prefabricated concrete is not excluded, comprises a peripheral wall 2 with stiffening ribs 3 and a base 4.
  • a base of this type is rigidly connected to and is preferably integral with the peripheral wall 2, the upper part of the container has an opening 5 which is closed by a top 6 which is in the shape of a conical roof in the embodiment illustrated in Figure 2.
  • a top 6 of this type comprises a hatch 7 provided with a cover 8 which can be secured in position by means of conventional bolts 9.
  • the hatch 7 is provided in alignment with the longitudinal axis X-X of the container 2.
  • the protective container 1 is installed in a cavity in the ground and is disposed along the longitudinal axis X-X in the vertical position, leaving the top 5 open in order to allow the gas tank 10, which is likewise in the vertical position, to be introduced.
  • the tank 10 is provided with feet 11, which are integral with the base 12, and a filler connector 13 disposed in correspondence with the upper cap 14.
  • the conventional safety valve 15 and a gauge 16 for checking the internal pressure are provided adjacent the connector 13 on the tank 10.
  • the connector 13, the safety valve 15, the maintenance assembly with the checking pressure gauge 16, as well as level indicators and outlet connections for the liquid phase and any other parts necessary for the operation, are assembled on the cap 14 of the tank 10 in a position such that they are accessible through the hatch 7 when the tank 10 is disposed inside the container 1.
  • the transverse dimensions of the protective container 1 are larger than the transverse dimensions of the tank 10 such that a space 17 is produced around the tank.
  • This space 17 is preferably filled with inert material 18, such as, for example, sand, to form ballast for the container and to reduce the volume which may possibly be occupied by the gas in the event of an accidental loss from the tank 10.
  • inert material 18 such as, for example, sand
  • non-corrosive anti-freeze liquid can be introduced which can be heated by a heater 181 which can consist of an electrical resistance or a tube through which hot water or steam passes by conventional supply systems.
  • the degree of vaporization of the liquefied gas can be regulated and maintained constant.
  • a reduction of this type in the volume also reduces the possibility of explosive air / gas mixtures forming, increasing the safety of the installation.
  • tie rods 20 for anchoring the tank 10 such that the latter is stably positioned against the base 4 of the protective container are provided about the top opening 5.
  • the tie rods 20 can be secured to the tank by means of corresponding studs 21, integral with the cap 14 of the tank, and nuts 22 ( Figure 4).
  • the top 6 is provided with a collar 23 which is disposed about the hatch 7 and extends towards the interior of the container 1 and thus towards the tank 10 when the latter is positioned inside the container ( Figure 6).
  • the tank 10 is provided with a collar 24 which is rendered integral with the cap 14 itself, for example by means of welding, and which is disposed coaxially with the collar 23 of the wall 6.
  • a seal 25 is provided between the facing ends of the collars 23 and 24 and the connection components in the form of eccentric tie rods are schematically indicated 26.
  • the space formed by the space 17 and the space 30 together can, if necessary, be used to control any losses from the tank 10 containing pressurized liquefied gas.
  • a sensor 31 held on the wall 6 and connected to a signalling and warning apparatus 32 is located inside the space 30.
  • a possible variation of the pressure inside the spaces 17 and 30, detected by the sensor 31, can be indicative of incorrect sealing of the tank 10 and thus initiates the operation of the signalling and warning device 32.
  • the base 4 of the protective container 1 is provided with a plurality of eye-bolts 33 for connection to a ballast plate 34 for holding the container 1 in position in the cavity and to balance it against any hydrostatic forces which would tend to force it out of the cavity.
  • the eye-bolts 33 are to engage, in known manner, rings 35 countersunk in the concrete of the ballast plate 34 by means of bolts 36.
  • the top 6 is provided with a flat radial lip 37 to be superimposed on a corresponding radial lip 38 provided on the edge of the opening 5 defined by the peripheral wall 2.
  • An annular seal 39 is interposed between the lip 37 and the lip 38 and the connection means consist of a clamp 40 with a screw coupling 41.
  • the top 6 is provided with a housing 42 in which an annular seal 43 is disposed by means of which the top 6 rests on the upper cap 14 of the tank 10.
  • a space 17 with a fluid-tight seal is determined about the tank 10 containing the liquefied gas.
  • the space 17 can be filled with non-corrosive anti-freeze liquid which may possibly be heated by a heater 181 using the method and advantages described above.
  • the top 6 is provided with a pair of eye-bolts 44 used for moving the assembly during its installation.
  • the latter is provided with an internal cavity 48 which extends axially over a portion along the collar 23 where the thread 46 is provided, and which is filled with fire-resistant material, indicated 49 in Figure 9.
  • this material may consist of cement lightened with expanded clay or verniculite.
  • fire-resistant charged expanded polyurethanes can also be used.
  • the cover 8 which can in turn be made from self-extinguishing plastics material such as, for example, high-density polyethylene (945 g/l), is provided with a radial appendage 50 to be superposed on the appendage 45 when the cover has been screwed onto the thread 46.
  • plastics material such as, for example, high-density polyethylene (945 g/l)
  • a locking member 51 which can be actuated by a key 52, is used to lock the appendage 50 on the appendage 45 and thus to prevent the cover 8 from being unscrewed and removed by unauthorized persons.
  • the engagement between the locking member 51 and the appendages 45 and 50 is produced so as to resist possible tampering but nevertheless can be unscrewed if a greater thrust at a predetermined load, for example, a pressure of between 0.35 and 0.45 bar, should be produced below the cover 8, following possible losses of gas.
  • a further advantage connected with this cover structure, in addition to being fire-resistant, is that even agricultural equipment can travel over it without risk of damage to the buried tank.
  • the tank 10 can be repeatedly refilled via the charging connector 13 after the cover 8 has been removed from the hatch 7 without the latter impairing the sealing conditions of the space 17.
  • the underground installation according to the invention is thus hardly visible above the ground since in practice only the cover 8 of the hatch 7 remains in view and at the same time it adequately satisfies the safety standards.
