Definitions

  • the invention relates to a valve for a fluid bottle (s) as well as to a fluid bottle comprising such a valve.
  • the invention relates more particularly to a valve for a pressurized fluid bottle (s) comprising a body extending in a longitudinal direction and on which is mounted an accessory such as a pressure indicator, said accessory being made integral with the body of the pressure gauge.
  • valve by means of an elastic hooking system allowing limited movement of the accessory with respect to the valve body.
  • Accessories rigidly fixed to a valve and located near a quick gas connection can generate uncontrolled contacts or obstructions due to deformation, poor assembly, etc. The consequence can be an ejection of gas. a device connected under pressure to the valve.
  • the valve according to the invention is essentially characterized in that the attachment system comprises two grooves formed on two opposite side faces of the body and two flexible attachment tabs integral with the accessory, the ends of which are received respectively in the two grooves, the attachment system further comprising a clamping flange screwed onto the accessory and generating a force on the tabs in the direction of their retention in said respective grooves.
  • the connection system promotes a certain elasticity and a possible deflection of the accessory with respect to the valve but a breakage of the connection in the event of excessive stress (in particular radial) rather than too great a deformation.
  • the tap illustrated in [ Fig. 1 ] comprises an oblong body 2, for example of generally cylindrical shape extending in a longitudinal direction A (or longitudinal axis).
  • This body 2 houses a gas circuit which extends between a lower end 11 of the body and an upper end 12 forming a male connector provided with an orifice intended to be connected to a device for withdrawing or filling fluid.
  • the upper end of the body 2 has, for example, ribs under grooves for the rapid attachment of a claw or ball system.
  • the lower end of the body 2 is for example threaded for mounting in an orifice of a pressurized gas cylinder (cf. [ Fig. 1 ]).
  • the circuit comprises at least one valve or valve (not illustrated for the sake of simplicity).
  • the valve may include all or part of the elements of the valves described in the documents FR3054291A1 or FR2962519A1 .
  • An accessory 3 such as a pressure indicator is made integral with the body 2 of the valve by means of a resilient attachment system 5, 6, 7 allowing a limited movement of the accessory 3 relative to the body 2 of the valve.
  • the accessory 3 has for example a generally tubular shape and being arranged concentrically around said body 2 of the valve.
  • the hooking system comprises two grooves 7 formed on two opposite side faces of the body 2 and two tabs 4 or flexible hooking blades integral with the accessory 3, the ends of which are respectively received in the two grooves 7.
  • the tabs 4 are provided with one end of a projecting shape conjugated with the grooves 7.
  • the tabs s4 can be provided with notches to enable them to be removed using a conventional tool (such as a flat screwdriver type).
  • the two grooves 7 can be formed respectively on two plane faces of the body 2 which are parallel to the longitudinal direction A.
  • the two tabs are preferably made of plastic material and for example in one piece with part of the body of the accessory 3.
  • the hooking system further comprises a clamping flange 5 screwed onto the accessory 3 and generating a force on the tabs 4 in the direction of their retention in said respective grooves 7.
  • the clamping flange 5 comprises a perforated plate threaded onto the body 2 and resting on the body in a plane perpendicular to the longitudinal direction A. That is to say that the plate comprises a hole through which it is threaded along the body 2 until it comes into abutment on the body 2.
  • the perforated plate may include inclined edges or edges in the longitudinal direction and bearing against at least part of the legs 4.
  • the screwing of the clamp 5 on the accessory 3 generates a force of the inclined edges on the tabs in a direction transverse or oblique to the longitudinal axis A.
  • several (for example four) screws 6 can be screwed into a lower portion of the housing of the accessory 3. These screws are for example s screwed in a direction parallel to the longitudinal axis, A, for example downwardly. tap. This generates a force tending to raise the housing of the accessory 3 and tighten the tabs in their groove 7.
  • the elastic attachment system is sized to allow an elastic angular movement of less than 25 °, in particular less than 15 ° of the accessory 3 relative to the body 2 of the valve relative to the longitudinal axis A. This is that is to say that the accessory 3 can swivel or pivot relative to the body 2 of the valve with respect to the longitudinal direction.
  • the elastic attachment system allows an elastic angular movement of the limited accessory when it is subjected to a force of less than 20N, beyond this force the elastic attachment system ensuring a locking of the accessory relative to the body and / or a mechanical failure of a flexible element of the attachment system (for example the tabs 4).
  • the housing of the accessory 3 can house a pressure indicator in the bottle 10 on which the valve is mounted.
  • a perforated protective cap 11 can be arranged around this assembly.
  • This visual indicator 8 can be a moving part.
  • the housing comprises for this purpose orifices 9 or viewing windows opening onto peripheral faces of the housing allowing viewing in a position transverse to the longitudinal axis A.
  • the pressure indicating device may be of the type described in the document FR3042586A1 .
  • All or part of the mechanism and in particular the flange can be "pre-assembled" to facilitate the installation and fixing of the accessory 3.
  • the clamp 5 may be provided with a protruding shape on its internal periphery to promote its adjustment on the body 2 of the valve.
  • the accessory may contain an electronic component such as a communicating electronic chip, antenna or the like.
