Definitions

  • the invention relates to a pressurized fluid bottle.
  • Such a bottle is known from FR3042586A1 .
  • the invention relates more particularly to a bottle of pressurized fluid, in particular pressurized gas, comprising a valve housing a fluid circuit provided with at least one valve, the bottle comprising a pressure indicator device comprising a pressure-sensitive piston in the bottle and movable relative to the valve body according to the level of pressure in the bottle between at least a first retracted position and a second deployed position, the pressure indicator device further comprising at least one information carrier movable between at least two distinct positions or states to respectively symbolize at least two pressure levels depending on the position of the piston, the information carrier being movable relative to the tap between at least a first position and a second position, the information carrier being biased towards its second position via a return member, the pressure indicator device comprising a bu movable tee between a blocking position preventing the movement of the information carrier from its first position to its second position and an unlocking position allowing the movement of the information carrier from its first position to its second position.
  • This pressure gauge is generally mounted on a valve and protected with the valve by a protective cap. To be visible to the user, the pressure gauge is generally accessible via an opening in the protective cap.
  • An object of the present invention is to overcome all or part of the drawbacks of the prior art noted above.
  • the bottle according to the invention is essentially characterized in that the movable stopper is an intermediate part arranged between the piston and the support of information.
  • the tap 2 can for example be screwed into a threaded orifice of the bottle 1.
  • valve 2 could be connected according to other modes to one or more bottles and in particular to a frame of bottles.
  • the valve 3 is for example an isolation valve controlled manually or automatically, in particular via a handwheel or lever or via a valve pusher of a member (a separate valve) which is connected to the valve 2 secured to the bottle 1 in a removable manner. .
  • the internal fluidic circuit 5 of the valve 2 preferably extends between an upstream end communicating with the storage volume of the bottle 1 (at the storage pressure of the bottle 1) and a downstream end opening at a connection of outlet, in particular a tapping and possibly filling connection.
  • the upstream and downstream ends can be located in a vertical longitudinal direction when the bottle 1 and the valve 2 are in the vertical position of use.
  • the circuit 5 may in particular comprise an isolation valve (valve) 3 and optionally a dust valve (not shown) arranged at the level of the terminal downstream end.
  • a dust valve not shown
  • the bottle 1 includes a pressure indicator device comprising at least one piston 4 sensitive to the pressure in the bottle 1 and movable relative to the body of the valve 2 according to the level of pressure in the bottle 1.
  • the piston 4 is preferably mounted in the body of the valve 2, for example transversely to the vertical longitudinal axis of the valve 2 and of the bottle 1.
  • the piston 4 is movable relative to the valve 2 between at least a first retracted position and a second deployed position.
  • the piston 4 is for example movable in translation.
  • the piston 4 may comprise a first end in communication with the fluidic circuit 5 of the valve 2 (upstream of the valve 3 of isolation) and a second end oriented towards the outside of the valve 2.
  • the pressure indicator device comprises at least one movable information carrier 6 intended to cooperate mechanically with the piston 4 in at least one position.
  • the information support 6 is mobile, for example in translation, between at least two distinct positions or states to respectively symbolize at least two pressure levels depending on the position of the piston 4 with respect to the valve 2.
  • the information carrier 6 may for example comprise a sleeve, for example of generally cylindrical shape, mounted to move (vertical sliding in a direction parallel to the vertical axis of the bottle).
  • the information support 6 can be movable relative to a support 11 fixedly mounted on the body of the valve 2. This support 11 can advantageously guide the movement of the information support 6 (for example in translation).
  • the information medium 6 may comprise an external face provided with visual information comprising at least among: an area of one or more color(s) or tint(s) (red/yellow/green) and/or one or more alpha-numeric symbols.
  • visual information comprising at least among: an area of one or more color(s) or tint(s) (red/yellow/green) and/or one or more alpha-numeric symbols.
  • the visual information may or may not be exposed depending on the position of the at least one support 6 with respect to the valve 2 or with respect to a possible cap.
  • the information support 6 is, for example, movable in translation in a direction parallel to the vertical longitudinal axis of the bottle 1.
  • the bottle 1 can be provided with a valve protection cap 2.
  • the cap can conventionally comprise a structure rigid defining a protective volume around the tap (rigid wall(s), perforated or not) .
  • the cap may comprise at least one opening on its periphery forming a window for viewing the position or the state of the information medium 6 .
  • the information medium 6 may for example be visible through an opening in a viewing direction, in particular a viewing direction which is perpendicular to the vertical axis of the bottle 1 (in the vertical position of use of the bottle ).
  • the information support 6 is movable relative to the tap 2 and to the bottle 1 between at least a first position (for example low) and a second distinct position (for example high).
  • the information medium 6 is also urged towards its second position via a return member 7 (in particular a spring).
  • the return member 7 acts directly (or via an intermediate piece, for example via the support 11) on the information support 6 to move it to its second position.
  • This reminder member 7 preferably acts only on the mobile information support 6 and not on the piston 4.
  • the piston 4 does not act directly on the support 6 of information but via a movable stop 8 which is a separate intermediate part of the piston 4 and the support 6 of information. This movable stop 8 is arranged between the piston 4 and the support 6 of information.
  • the mobile stop 8 can be moved between a blocking position preventing the movement of the information carrier 6 from its first position ([ Fig. 1 ] and [ Fig. 4 ]) to its second position and an unlock position ([ Fig. 3 ] and [ Fig. 5 ]) allowing the movement of the information medium 6 from its first position to its second position.
  • an unlock position [ Fig. 3 ] and [ Fig. 5 ]
  • There [ Fig. 6 ] also symbolizes via arrows the passage of the movable stop to the second unlocking position and the movement of the information carrier 6 to its second position.).
  • the mobile stop 8 can be a part mounted mobile in translation on the valve 2 in a direction parallel to the direction of movement of the piston 4 (transverse to the vertical longitudinal axis of the bottle 1 and of the valve 2).
  • the mobile stop 8 can comprise a part of annular shape mounted around the body of the valve 2.
  • the mobile stop 8 can be guided in translation via lugs cooperating with oblong orifices formed in the body of the mobile stop 8.
  • This movable stop 8 preferably comprises a first end cooperating with the piston 4 and a second end cooperating with a return member 9.
  • This return member 9 of the movable stopper 8 generates a force on the second end of the movable stopper 8 which is transmitted to the piston 4 via the first end of the movable stopper and to urge the piston 4 towards its retracted position.
  • the member 9 for recalling the mobile stop 8 comprises for example a compression spring pressurized between the valve body 2 and the second end of the mobile stop 8.
  • the blocking or not of the information carrier 6 by the movable stopper 8 can be obtained, for example, via at least one end 10 of the information carrier 6 which is received in a slot 12 of the movable stopper 8.
  • this slot or slot 12 has a variable dimension depending on the direction of movement of the mobile stop 8.
  • the end(s) 10 are blocked in the slot 12 (cf. [ Fig. 4 ]) while in the unlocking position of the mobile stop 8, the end(s) 10 can pass through the slot 12 (cf. [ Fig. 4 ]).
  • the ends may have an intermediate portion which is received in the slot 12 regardless of the relative position of the mobile stop 8 and a head or protuberance which can only pass through part of the slot of sufficient size (in unlocked position).
  • the first end of the movable stop bears on the terminal end of the piston 4 while that on the other side of the valve body 2 are arranged the return member 9 of the movable stop and the second end of the stop 8 movable.
  • the first and second ends of the movable abutment 8 can be located respectively at two diametrically opposite ends.
  • This return member 9 of the mobile stop 8 can be the only return member which urges the piston 4 towards its first retracted position.
  • this element 9 for returning the piston 4 to its first retracted position can be arranged outside of the valve body 2. That is to say that this return member 9 can be easily accessible from the outside instead of being encapsulated or mounted in the body of the valve 2 as according to the solution of the prior art . This allows easier maintenance and in particular the change of reminder member 9 to modify, if necessary, the calibration of the force on the piston 4 depending for example on the storage pressure of the bottle 1.
  • the pressure indicator device can thus use a single piston 4 and a mechanism that is reliable, simple and inexpensive. Of course, several pistons could be envisaged.
  • the pressure indicator 6 can indicate more than two distinct states or pressures. Thus, it is possible to envisage the display of three or more different pressure levels (four, five, etc.) depending on the position of the piston 4 via one or two information support(s) 6 (or more ).
