    专利说明:

    The invention relates to a device for supplying pressurized fluid.
    The invention relates more particularly to a device for supplying pressurized fluid, in particular pressurized gas, comprising at least one pressurized fluid reservoir provided with an orifice connected to a first tap, the first tap housing an internal fluid circuit provided with at least one closing valve, the device comprising a second valve mechanically connected in a separable manner to the first valve, the second valve comprising an internal circuit for transferring pressurized fluid, in the connected position of the second valve on the first valve, the internal circuit of the second valve being fluidly connected to the internal circuit of the first valve, the second valve comprising a movable actuating member intended to open the at least one closing valve of the first valve, the second valve further comprising a control member mobile, in particular manually, provided for controlling the movement of the actuating member and c order the opening or not of the closing valve of the first tap, the device comprising a residual pressure valve configured to prevent the complete emptying of the at least one tank below a determined pressure threshold when the at least closing valve is open,
    The invention relates in particular to a device for distributing fluid, in particular pressurized gas of modular type. The invention relates in particular to filling gas cylinders at high pressure (for example between 200 and 700 bar).
    Examples of modular fluid distribution devices are illustrated in the documents FR2892799A1, FR2979687A1, FR2970313A1 FR3022972A1 or FR303386A1.
    To avoid contamination of bottles or sets of bottles, it is known to provide a residual pressure valve within the bottle or the tap attached to it cf. for example FR303386A1.
    Such a residual pressure valve conventionally prevents the total emptying of the bottle below a determined pressure threshold. This prevents the intrusion of air and humidity, especially when the bottle (its tap) is kept open until it is completely drained.
    This solution, although satisfactory can sometimes complicate the structure and the cost of the bottle or its tap attached to it and prove to be complex.
    In addition, such a residual pressure valve housed in the bottle can be subjected to sudden emptying (withdrawal with Joule-Thompson effect) and rapid filling. Thus, such a valve can be subjected to extreme conditions with fluid passages in both directions.
    An object of the present invention is to provide a fluid supply device having a simple, compact structure, good ergonomics of use and good safety with respect to possible pollution from inside the tank.
    An object of the present invention is to overcome all or part of the drawbacks of the prior art noted above.
    To this end, the device according to the invention, moreover in accordance with the generic definition given in the preamble above, is essentially characterized in that the residual pressure valve is located in the second tap.
    Furthermore, embodiments of the invention may include one or more of the following characteristics:
    - the internal fluid transfer circuit of the second valve includes an upstream end intended to be connected to a downstream end of the internal circuit of the first valve and at least one first downstream end opening at an outlet connection, the outlet connection being intended to be fluidly connected with a member receiving gas withdrawn from the reservoir, the residual pressure valve being located in the internal fluid transfer circuit of the second valve between the upstream end and the downstream end,
    - the residual pressure valve comprises a movable closure member urged by a return member towards a seat in a closed position of the internal circuit of the second valve, the closure member being subjected to the force of the fluid under pressure in said internal circuit coming from the upstream end and which is exerted against the force of the return member,
    the internal circuit of the second valve comprises a second downstream end opening onto the body of the second valve and comprising a purge valve mechanically operable to open the second downstream end of the circuit towards the outside of the second valve in order to purge said internal circuit,
    - the mobile actuating member forms a valve pusher intended to move the at least one closing valve by mechanical actuation,
    - The internal circuit of the first valve comprises two closing valves arranged in series, and in that the actuating member is movable in translation and configured to open the closing valves in series by mechanical actuation of a first closing valve so that the movement of this first closing valve pushes and in reaction moves the following closing valve (5),
    the first and the second tap comprise respective hooking members forming a removable quick connection system from the second tap to the first tap,
    - the mobile control member comprises a lever mounted articulated on the second tap or a button mobile in rotation and / or in translation,
    - the movable actuator comprises an axis movable in translation.
    The invention may also relate to any alternative device or process comprising any combination of the above or below characteristics within the scope of the claims.
    Other particularities and advantages will appear on reading the description below, made with reference to the figures in which:
    - Figure 1 shows a schematic and partial sectional view of a first possible embodiment of the fluid supply device according to the invention,
    - Figures 2 and 3 show sectional views, schematic and partial, of another possible embodiment of the fluid supply device and according to two configurations or states of use respectively.
    The device 1 for supplying pressurized fluid illustrated in FIG. 1 comprises a reservoir 2 (for example a bottle) of pressurized fluid provided with an orifice in which is fixed (screwing for example) a first tap 3.
    The first tap 3 houses an internal fluid circuit 4 provided with at least one closing valve 5. This internal circuit 4 comprises, for example, a first upstream end in relation to the storage volume of the tank 2 and a downstream end 13 opening for example onto one end of the body of the first tap 3.
    The device 1 also comprises a second tap 6 mechanically connected in a separable (removable) manner to the first tap 3.
    For example, the first 3 and the second tap 6 comprise respective hooking members 8, 9 forming a removable quick connection system of the second tap 6 on the first tap (cf. FIGS. 2 and 3).
    The second valve 6 also includes an internal circuit 7 for transferring pressurized fluid. In the connected position of the second valve 6 on the first valve 3, the internal circuit 7 of the second valve 6 is fluidly connected to the internal circuit 4 of the first valve 3. For example, an upstream end 12 of the internal circuit 7 of the second valve 6 is connected at the downstream end 13 of the circuit 4 of the first tap 3
    The second valve 6 comprises a movable actuating member 9 preferably forming a valve pusher intended to open by mechanical actuation the at least one valve 5 for closing the first valve 3. In addition, the second valve 6 comprises a member 10 of mobile control, preferably manually operable, designed to control the movement of the actuating member 9 to control the opening or not of the valve 5 for closing the first valve.
    As illustrated in the figures, the mobile control member 10 can comprise or consist of at least one of: a lever mounted articulated on the second tap 6 (cf. FIGS. 2 and 3), a button or wheel which is movable in rotation and / or in translation (see Figure 1) on the valve body 6.
    The device 1 further comprises a residual pressure valve 11 configured to prevent the complete emptying of the tank 2 below a determined pressure threshold (for example between 1.5 and 10 bar, in particular between 2 and 10 bar).
    According to an advantageous feature, the residual pressure valve 11 is located in the second 6 tap. That is to say that the function of maintaining a residual pressure is performed only by the second valve 6 which is connected to the first valve 3. This makes it possible to simplify the architecture of the first valve 3 without harming the protection contents of tank 2.
    For example, the internal circuit 7 of the second valve 6 comprises an upstream end 12 intended to be connected to the downstream end 13 of the internal circuit 4 of the first valve 3 and a first downstream end 14 opening out at an outlet connector 15 . The outlet connector 15 is for example intended to be fluidly connected with a member receiving the gas withdrawn from the tank 2.
    The residual pressure valve 11 is located in the internal circuit 7 of the second valve 6 between the upstream end 12 and the downstream end 13, preferably near the outlet connector 15.
    As shown in FIGS. 2 and 3, the residual pressure valve 11 comprises for example a movable closing member 111 (piston for example) urged by a return member 211 (spring for example) towards a seat in a closed position of the circuit internal 7 of the second tap 6. This closing member 211 is subjected to the force of the pressurized fluid in said internal circuit 7 coming from the upstream end 12. This pressure force tends to oppose the force of the '211 reminder unit. Thus, according to the dimensioning of the residual pressure valve 11, this prevents the outlet of fluid (valve closed under the action of spring 211) when the pressure upstream is below a determined threshold.
    The residual pressure valve 11 can also incorporate a non-return function (“NRV” = “No Return Valve”) preventing the flow of gas between the downstream end 14 and the upstream end 12 (thus preventing untimely filling ).
    As illustrated in the figures, the internal circuit 7 of the second valve 6 can comprise a separate second downstream end 16 opening onto the body of the second valve 6. The two downstream ends 16, 14 can be connected in parallel to the upstream end 12 of the circuit 7 internal.
    This second downstream end 16 can be provided with a purge valve 17 which can be actuated preferably mechanically (for example manually) to open the second downstream end 16 of the circuit towards the outside of the second tap 6 in order to purge said internal circuit 7. This thus makes it possible to depressurize the internal circuit 7 of the second tap for example, before separating the second tap 6 from the first tap 3.
    Of course, the invention is not limited to the embodiment described above.
    Thus, as shown in Figures 2 and 3, the internal circuit 4 of the first valve 3 may include two closing valves 5, 17 arranged in series.
    In the closed position, a first valve 17 can be flush with one end of the first valve 3.
    The actuating member 9 can be movable in translation to form a valve pusher configured to open the valves 17, 5 for closing in series by mechanical actuation of a first valve 17 for closing so that the movement of this first valve 17 closing (movement in the body of the first valve 3) pushes or allows the movement of the valve 5 following closure (see Figures 2 and 3 and the document WO2012004481A1 for example).
    Likewise, the first tap 3 could have three valves in series (or more and / or other components). Reference may be made, for example, to the example of document WO2016139404A1 for the sequence of opening three valves in series.
    Thus, when the second valve 6 (which ensures the opening of the valve (s) 17, 5) is detached from the first valve 3, the closing valve (s) 17, 5 close automatically (under the action of organ (s) return system such as springs) the internal circuit 4 of the first valve 3. Thus, pollution or complete emptying of the tank 2 is avoided. When the second tap 6 is connected to the first tap 3 and opens the internal circuit 4 of the first tap (via the displacement of the valve (s) 17, 5) complete emptying or pollution of the tank 2 is not possible even if the user forgets to move the control member 10 to the closed position of the internal circuit 4.
    As illustrated diagrammatically in FIGS. 2 and 3, the closure valve (s) 17, 5 may comprise a movable element (piston) urged towards a seat by a return member (spring for example).
    In the example of FIGS. 2 and 3, the movable actuating member 9 comprises an axis movable in translation. Of course this could be replaced by any other suitable system.
    Likewise, the invention has been described with a single tank 2 but could be applied to a set of tanks (bottle frame for example) connected to the first valve 3. In addition, the second valve may include an adjustable pressure regulator or not to lower the gas pressure to a determined level. For example, the regulator is located in the internal circuit 7 or at the outlet connector 15.
