  • the invention particularly relates to industrial or medical gas cylinders stored in compressed or dissolved form.
  • the gas pressure is equal to the conditioning pressure of the gas contained in the bottle. That is to say, no expansion system is integrated in the tap.
  • the user To dispose of the gas at the operating pressure, the user must use a separate holder (usually a pressure gauge) which is connected to the valve outlet. In this way, the high pressure contained in the bottle is brought to a relaxed pressure of use.
  • This structure concerns the vast majority of industrial gas cylinders around the world. The valve is not necessarily protected in case of fall by a protective cap. In all cases, the pressure reducer is not protected against shocks.

  • the device further comprises a separate pressure regulator 6 selectively connectable to the valve 4.
  • This removable pressure regulator 6 is thus provided to provide a second expansion at a still lower pressure (for example less than 10 bar) in the case where the valve 4 already incorporates a pre-relaxation body.
  • the holder 6 is connected to the valve 4 through an opening of the cap 3, for example superior.
  • the expander 6 is housed at least partially within the protective volume defined by the cap 3.
  • the regulator 6 conventionally comprises an internal circuit 16 of fluid.

  • the internal circuit of the expander comprises a second end 46 intended to be connected to a user device gas drawn and relaxed.
  • the internal fluid circuit 16 of the expander 6 comprises for example a member 26 for expanding the pressure of the fluid to a predetermined fixed or adjustable value.
  • the cap 3 defines a protective volume around the valve 4 having a shape complementary to at least a portion of the outer shape of the expansion valve 6. More specifically, the constituent material of the cap 3 delimits a complementary housing 8 conjugate at least a portion of the outer shape of the expander 6 when the latter is in the connected position on the valve 4.

  • the cap 3 is shaped for guiding the regulator 6 for mounting it on the valve 4.
  • the mounting of the expander 6 in the position connected to the valve 4 from a detached position requires the combination of at least two relative movements of the expander 6 relative to the cap 3, the at least two relative movements having distinct directions. or different natures (translation / rotation).
  • These movements can comprise one or more movements among: a vertical translation, a horizontal translation, a rotation along a vertical axis, a rotation in a horizontal direction.
  • the Figures 4 to 6 illustrate an example sequence in which the assembly requires a translation of the expander 6 in the cap 3 in the vertical direction, the expander 6 having a determined orientation to allow its entry into the protective volume of the cap 3 (passage of the figure 4 to the figure 5 ).
  • the regulator 6 is then rotated relative to the cap 3 around an axis of vertical revolution (passage of the figure 5 to the figure 6 ).
  • the movement required for disassembly is, for example, the reverse of assembly.
  • the constituent material of the cap 3 defining the housing 8 for the expander 6 forms a stop preventing or limiting the direct ejection of the expander 6 out of the cap 3.
  • the cap blocks the ejection of the expander 6 through an opening hat 3 (vertically and / or laterally).
  • the cap 3 protects the regulator 6 in its housing 8.
  • This housing architecture 8 complementary to the regulator 6 also prohibits the mounting of a regulator 6 which is not adapted to that provided for the contents of the bottle and in particular in the case of a regulator whose use is incompatible (because too weak) with the pressure delivered by the valve 4.
  • the valve 4 comprises a member 5 of the manually operated isolation valve 37 such as a lever, a knob or a rotary wheel.
  • the control member 5 of the isolation valve 37 consists of a lever articulated on the valve body 4.

  • the 5 control member comprises a hook portion which is hooked selectively on a portion 9 conjugate of the expander 6 (for example an axis 9, cf. figure 3 ). This gives additional security to the whole.
  • the control member 5 can participate in the good fluid connection between the two ends 27, 36 of the two internal circuits 7, 16 of the valve 4 and the expander 6.
  • the cap 3 may be made of plastic, polymer and / or composite, and obtained by a molding technique for example.
  • the cap 3 may also be composed in part or in whole of metal, steel or aluminum machined or obtained by a foundry technique or stamping.
  • the shape of the housing 8 for the expander 6 is preferably made in three dimensions in the cap 3.
  • the complete device incorporating the bottle 1, the flange 2, the cap 3, the valve 4, the control member 5 and the expander 6 may require the mounting of different relative indexing elements relative to each other.
  • the mounting of the cap 3 can be indexed with respect to the bottle 1 by means of a collar 2.
  • the mounting of the valve 4 can be indexed relative to the bottle 1, so that the assembly the regulator 6 is indexed with respect to the bottle and the tap 4.
  • An advantage of the device described above lies in the fact that the fluid connection system between the valve 4 and the expander 6 can be of the fast connection type without the need to provide a complex or expensive mechanism. Indeed, a simple connection of the male-female type may be suitable and can replace a connection system generally screw type or type connection quick connection bayonet for example because the cap 3 provides guidance, protection and very secure maintenance .

  • the lever 5 in its second position the lever 5 forms a stop in the cap 3 preventing the mounting of the expander 6 in the connected position and nested on the valve 4.
  • the movement of the lever 5 in its first position suppresses this stop. That is to say that the mounting of the regulator 6 in the position connected to the valve 4 from a detached position requires a movement of the lever 5 in its first position.
  • the housing 8 is shaped so that the mounting of the expander 6 and its engagement in the housing 8 in the connected position on the connector 127 requires only a translation of the expander 6 relative to the cap 3 in a direction parallel to the longitudinal axis of the bottle 1 (when the outer shape of the expander 6 is compared with the conjugate form of the housing 8).
  • the disassembly of the valve 6 can be obtained only by giving the regulator 6 a translational movement relative to the connector 127 (relative translation upwards on the figure 9 ).
  • a portion of the expander 6 protrudes out of the housing 8 and remains accessible manually by a user, for example to allow the manipulation of a flow control member and / or the regulated pressure located on the regulator 6 (for example a graduated handwheel).

This ensures the maintenance, blocking and protection of the regulator 6 in the housing 8 of the cap 4.
  • the introduction of the expander 6 in the housing 8 may require a combination of movements (rotation + translation).
  • the holding, locking and protection of the expander 6 in the housing 8 of the cap 4 are further strengthened when the assembly / disassembly of the expander 6 requires a combination of different movements relative to the cap 4.
