    [0001] The invention relates to a gas distribution valve block, with or without an integrated expansion system, for equipping a gas container or the like, as well as a gas distribution assembly comprising a cylinder of gas, in particular gas medical, and such a valve block attached to the gas cylinder, and preferably with a protective cover arranged around the valve block to protect it from shocks and dirt. Industrial and medical gases are commonly packaged at high pressure in gas containers, typically gas cylinders, equipped with a valve block, with or without built-in expansion valve, namely a single tap open / closed type or a tap to integrated regulator, also called RDI, to control flow and pressure of the delivered gas. In order to protect this valve block, it is common to arrange around said valve block, a protective cover forming a protective shell around the valve body. Such a cowling is commonly called "hat". Cowlings of this type are described in particular by the documents EP-A-629812, DE-A-10057469, US-A-2004/020793 and EP-A-2586481.
    [0002] Conventionally, the gases are conditioned at high pressure in the gas containers, such as gas cylinders, that is to say typically at pressures greater than 100 bar absolute, generally between 200 and 350 bar abs, or more. The high-pressure gas exiting the container must therefore be expanded before it can be used, that is to say its pressure must be reduced to a lower operating pressure, called low pressure, for example a pressure less than 20 bar abs, or even often less than 10 bar abs. The expansion of the gas can be done either directly in the valve block itself, when it is an integrated pressure regulator valve block, also called RDI, or downstream of the valve block by means of a pressure reducer device. gas.
    [0003] In all cases, in order to measure and control the pressure of the gas contained in the bottle to which the valve block is attached, whether with or without a built-in pressure reducer, a pressure indicator device, such as a manometer, is generally used. the pressure tap is in fluid communication with the gas passage passing through the valve block and carrying the high pressure gas from the bottle.
    [0004] Since the high pressure gas enters the valve block through its lower part, i.e. its lower half, which is attached to the container and which carries the gas inlet port of the valve block, the pressure indicator device, typically a pressure gauge, is also generally arranged in the lower part of the valve block, that is to say closer to the entrance of the high pressure in the valve body. This also responds to technical constraints related to the dimensions of the valve block. Similarly, it is also possible to use a gas autonomy indicator device to determine the use time corresponding to the amount of residual gas in the gas container equipped with the valve block. However, the need to position this device indicating pressure or gas autonomy in the lower part of the valve block makes it often difficult or not easy to read the pressure value or range of gas indicated by it , which leads to reading errors or to an obligation for the user to position himself in a certain way with respect to the bottle in order to make possible a correct reading of the pressure or autonomy value given by the indicating device pressure or autonomy. In view of this, the problem is to improve the comfort and / or readability of the pressure indicator device or gas autonomy, preferably a manometer, equipping a valve block gas distribution, typically for bottle or other gas container, avoiding the aforementioned drawbacks, that is to say to propose a faucet block of improved design. The solution of the invention is then a gas distribution valve block comprising: - a valve body comprising a lower part comprising a fastening system for fixing the valve block to a gas container, and an upper portion overcoming the portion lower, the lower part of the valve body comprising a gas inlet port through which a gas can enter the valve body, - at least one gas outlet port through which the gas can emerge from the valve body, - a first internal gas passage fluidly connecting the gas inlet port to the gas outlet port, and - a pressure indicator device or gas autonomy device attached to the valve body, such as a pressure gauge, characterized in that that: - the valve body comprises a second internal gas passage fluidly connected to the first internal gas passage so that the gas pressure exerted in said second internal gas passage is equal (ie strictly equal to or approximately equal to) that exerted in the first internal gas passage upstream of the fluidic connection site of the first and second internal gas passages, and - the device indicating pressure or autonomy in gas is attached to the valve body at its upper end, and comprises a pressure tap in fluid communication with the second internal gas passage so as to measure the pressure of the gas within said second internal gas passage. Depending on the case, the valve block of the invention may comprise one or more of the following technical characteristics: it comprises a gas passage control system arranged on the first internal gas passage, and a control member operable by a user and cooperating with the gas passage control system to control the passage of gas in the first internal gas passage, in the direction from the gas inlet port to the gas outlet port, c that is, to adjust the flow rate of the delivered gas. - The device indicating the contents of the bottle is a pressure indicator - the device indicating the contents of the bottle is a pressure gauge .. - The device indicating the contents of the bottle is an indicator of autonomy in gas. the device indicating the contents of the bottle is a needle or digital device indicating an estimate of the duration of use of the gas corresponding to the quantity of residual gas in the bottle. the device indicating the contents of the bottle is preferably an electronic device which calculates and displays a gas autonomy expressed in units of time. the valve body comprises a gas expansion system arranged between the fluidic connection site of the first and second internal gas passages, and the gas outlet orifice. According to this embodiment, it is therefore an integrated regulator valve or RDI. the axis BB of the pressure indicator device forms with the axis AA of the valve body an angle of between 0 and 90 °, preferably between 10 ° and 80 °, more preferably between 25 ° and 70 °. - The gas outlet port is carried by a gas outlet fitting, located between the upper and lower parts of the valve body for example. - The expansion system comprises a high pressure chamber, a valve and a valve seat, and a low pressure chamber. - The gas passage control system comprises a movable element carrying calibrated orifices having increasing dimensions corresponding to increasing gas flow values. the movable element of the gas passage control system is a rotating disk.

The invention also relates to a gas distribution assembly comprising a gas container, such as a gas cylinder, and a valve block attached to said gas container, said valve block being as described above.

    [0006] The invention further relates to a use of a valve block according to the invention or a gas distribution assembly according to the invention for dispensing a gas or gas mixture, preferably a gas or medical gas mixture. Preferably, the gas or gas mixture is chosen from oxygen, air, N 2 O 2, He 2 O 2, NO / nitrogen. The invention will now be better understood thanks to the following detailed description, given for illustrative purposes but not FIG. 1 shows an embodiment of a cylinder / valve block / valve assembly according to the invention, and FIGS. 2 and 3 represent sectional views of the valve block. DESCRIPTION OF THE PREFERRED EMBODIMENTS According to the invention of the assembly of Figure 1, - Figure 4 schematizes the operating principle of the valve block according to the invention of the assembly of Figure 1, and - Figure 5 shows a sectional view of valve block of Figure 2 according to the invention arranged in a protective casing. Figure 1 shows an embodiment of a rigid protective cover 21, commonly called "cap", arranged around a valve block 1 according to the invention (visible in Fig. 5), namely a valve block with or without integrated expansion valve, itself attached to the neck 20 of a gas cylinder 20, said protective hood 21 being provided with a carrying handle 25 according to the present invention. The gas bottle 20 typically has a cylindrical steel body and a size between 10 and 150 cm, and a capacity of 0.5 to 20 liters (in water equivalent). The protective cowling 21 makes it possible to protect the valve block 1 against impacts, whether the valve block 1 is of the type with integrated expansion valve or RDI, or of the type without integrated expansion valve. The fixing around the valve block 1 on the neck of the gas bottle 20 is done by screwing, via reciprocal threads carried by the inner surface of the neck of the bottle 20, on the one hand, and by the outer surface of the an expansion 12 of substantially cylindrical or conical shape, located at the base of the valve body 1 and carrying the gas inlet port 2, as shown in Figures 2 and 5, on the other hand.
    [0007] More specifically, the protective casing 1 comprises a casing body forming a protective shell around an internal volume sized to receive the valve block 1, and a carrying handle 25 designed to be handled by a user. The casing body 21 is typically made of a polymer and / or metal type material, preferably made of plastic material, such as PVC, PE, PET, PP, PMMA, PU, PA ... The carrying handle 25 is formed of a rigid material, such as a polymer or a metal or metal alloy, and is carried by one or more support posts 24 mechanically connecting the casing body to the carrying handle 25. The carrying handle 25 is generally arranged horizontally, c ' that is to say perpendicularly or almost perpendicular to the vertical axis of the bottle 20 and the cowling 21. The carrying handle 25 has an elongated shape, whether straight or curved, typically a length less than 20 cm, typically 6 to 15 cm. One or more support posts 24 are attached to the carrying handle 25 so as to allow a user to easily transport the assembly comprising the cap 21, the valve 1 and the bottle 20 by means of said carrying handle 25. The support posts 24 may be formed of a plastic material, such as the body of the cowling 21, but also of aluminum alloy or any other metallic material. They can be attached to the handle 25 by screwing or welding, for example, or formed in one piece.
    [0008] The protective cowl 21 also has openings giving access to the valve block 1 located in the internal volume of the cowl body. In particular, a first opening 22 is provided at the top 21a, also called the upper part, of the protective cowling 21, within which is housed a pressure indicator device 7, namely here a manometer, or at needle, which is electronic. The lower part 21b, also called the lower part, of the cowling 21 is positioned around at least a portion of the neck of the bottle 20, as can be seen in FIG. 1. More precisely, the protective cowling 21 comprises a flat surface 26 at its upper part 21a, that is to say at the top of the cowling, within which is arranged the first opening 22. The flat surface 26 is in fact an oblique face with respect to the axis CC of the bottle 20 Preferably, the flat surface 26 is perpendicular to the axis BB of the pressure indicator device 7, as shown schematically in FIG. 1. Typically, the axes CC of the bottle 20 and AA of the valve block 1 are merged. say coaxial.
    [0009] Furthermore, the protective cowling 21 comprises a second opening 27 arranged in front or front face of the protective cowling, within which is housed the rotary wheel 5 controlling the flow of the gas passing through the valve block 1, as explained below. after in relation with Figures 2 and 3.
    [0010] In the embodiment of Figure 1, the rotary handwheel 5 is arranged around the gas outlet fitting 13 carrying the gas outlet port 6 for withdrawing the gas stored in the bottle 20. However, the rotary handwheel 5 can be arranged differently, that is to say be non-coaxial with the gas outlet connection 13. Furthermore, the valve block 1 also comprises a filling connector 17 with an internal valve 18, (see FIG. 5), which filling connector 17 serves to introduce pressurized gas into the bottle 20 when it is empty or almost empty. In addition, in order to allow the hooking or securing of the bottle / valve block / cowling assembly to a support, such as a hospital bed or stretcher bar, the protective cowling 21 comprises, on the side of its rear face, a hooking device 28 pivoting between a fully folded position, called "rest" (shown schematically in Figure 1), that is to say the position adopted by the attachment device 28 when it is stored and in contact or quasi-contact body of the cowling 21, and a fully unfolded position called "hooking" (not shown), that is to say the position adopted by the attachment device 28 when is completely out and can be hooked to a support, such as a bed rail or the like.
    [0011] In all cases, the pressure indicator device 7 is fixed to the body 1 of the valve block which is located in the internal volume of the cowling 21, as can be seen in FIGS. 2 and 3. Such an arrangement of the pressure indicator device 7 in position high on the valve block 1 and on the front of the cowling 21 makes it considerably easier to read the pressure delivered by the pressure indicator device 7 and avoids reading errors.
    [0012] Preferably, as illustrated in FIG. 2, the axis BB of the manometer 7 and the axis AA of the valve block 1 form an angle α of between 0 and 90 °, in particular between 10 ° and 80 °, preferably between 25 ° and 70 °, typically of the order of 35 to 55 °. As detailed in Figures 2 and 3, the gas distribution valve block of the invention comprises a valve body 1 schematically comprising an upper portion forming the top of the valve block 1, and a lower portion 1b forming the base of the valve block 1. The upper part thus overcomes the lower part or base lb of the block 1.
    [0013] The lower part 1b of the valve block 1 comprises the fixing system 12a, such as a thread, for fixing the valve block 1 to the bottle 20, as already explained, as well as the gas inlet port 2 through which a gas under pressure from the bottle 20, can enter the valve body 1 and then be conveyed to the outlet port 6 of gas carried by the outlet connector 13 through which the gas can emerge from the body 1 of tap. As already explained, the lower portion 1b of the valve body 1 is shaped to be fixed by screwing. To do this, the lower portion 1b has an expansion 12 of the downwardly projecting body, of generally cylindrical or conical shape and carrying a thread 12a on its outer surface adapted to cooperate by screwing with a complementary thread or tapping arranged in the bottle neck 20. A first internal gas passage 3 fluidly connects the gas inlet port 2 to the gas outlet port 6 carried by the outlet fitting 13. This first internal passage of gas 3 passes through axially the expansion 12 of body 1 of generally cylindrical or conical shape, as shown in Figure 1, said expansion 12 further carrying the gas inlet port 2. In addition, the valve block 1 also comprises a control system gas passage or flow 23 cooperating with the control member 5, namely here a rotary wheel operable by the user to control the passage of gas in the first internal gas passage 3, that is to say to say po ur allow or, conversely, prevent any flow of gas in said passage 3, in the direction from the gas inlet port 2 to the gas outlet port 6 carried by the outlet fitting 13. The gas flow control system 23 comprises a perforated element of calibrated holes, the steering wheel coming, as the case may be, to cooperate the calibrated hole corresponding to the desired flow rate with a fixed orifice, or to cooperate a movable orifice passage with the calibrated hole corresponding to the desired flow rate. Such an arrangement is conventional and known to those skilled in the art. Thus, according to the embodiment presented here, the pierced element of calibrated orifices is a movable metal disk traversed by calibrated orifices. The orifices have different sizes, i.e. increasing, each caliber corresponding to a given flow rate value. This disc is movable in rotation and driven by the flywheel 5. There is no check valve in the passage control system in the embodiment shown in the Figures. However, according to other more conventional designs incorporating an open / closed function in the high pressure part of the valve block, it can be provided that the steering wheel 5 also controls this open / closed function. In this case, integrating an opening / closing valve sealing the seat in the closed position may be necessary.
    [0014] In addition, the valve block also incorporates, as illustrated in FIG. 2, a movable valve 4 in translation, one or more seals 15, such as O-rings, and at least one return spring 14. The valve 4 is a residual pressure valve for maintaining a positive pressure permanently in the bottle. This valve 4 has an autonomous operation, without action of the steering wheel.
    [0015] In accordance with the present invention and illustrated in FIGS. 2 and 5, the valve body 1 comprises a second internal gas passage 11 fluidly connected to the first internal gas passage 3 at a junction or fluid connection site 10. The second passage internal gas 11 thus forms a bifurcation or a branch of the first internal passage of gas 3.
    [0016] The second internal gas passage 11 and at least the portion of the first internal gas passage 3 between the inlet orifice 2 and the fluidic junction site 10 convey high pressure gas coming directly from the gas bottle 20. These passages 11, 3 are therefore subjected to high pressure, typically pressures up to about 350 bar absolute. Furthermore, the pressure indicator device, here a pressure gauge 7, which is fixed to the valve body 1 at its upper end 1a, comprises a pressure tap 8, for example a channel or the like, in fluid communication with the second internal passage of gas 11 so as to measure the pressure of the gas within said second internal gas passage 11. The pressure tap 8 of the pressure indicator device 7 can be fluidly connected to the second internal gas passage 11 indirectly, by example via a junction passage 16 arranged in the body 1 of the valve and connecting the pressure tap 8 of the pressure indicator device 7 to the second internal gas passage 11, as shown in Figures 2, 3 and 5. In the embodiment 2, 3 and 5, the valve block is of RDI type, that is to say it comprises a gas expansion system 9 arranged between the fluid connection site 10 of the first and second internals 3, 11, and the gas outlet port 6 so as to reduce the pressure of the high-pressure gas from the bottle 20 to a lower pressure value, for example a passage from a high pressure above 100 bar to a low pressure of less than 20 bar abs. For this purpose, conventionally, there is provided an expansion system 9 comprising an expansion valve and a valve seat. The final pressure can be adjustable or fixed value.
    [0017] As can be seen in FIGS. 2, 3 and 5, the gas flowing in the second internal gas passage 11 is not subjected to expansion within the expansion system 9 since the junction or fluid connection site 10 between the first and second second passages 3, 11 of gas is located upstream of the expansion system 9. The junction or fluid connection site 10 is typically the so-called high pressure chamber of the expansion system 9, which high pressure chamber is then crossed by the high pressure gas brought therein by the first passage 3 of gas. Part of the high pressure gas is then discharged through the second gas passage 11 which then conveys it to the pressure tap 8 of the manometer 7 so as to measure the pressure of said gas.
    [0018] Figure 3 provides a better view of the expansion system 9 and the high pressure chamber 10. More precisely, in addition to the pressure tap 8 and the pressure gauge 7, there is shown the elongate expansion valve, i. e. the valve seat, an expansion spring and a detent piston which determines the position of the expansion valve according to the force of the expansion spring, the high pressure and the low pressure.
    [0019] All these elements are also visible in Figure 4 which shows schematically the operating principle of the valve block according to the invention. It also shows that the valve block also comprises an internal filter 19, as well as arranged downstream of the expansion system 9, a valve 29 and a low pressure gas outlet with isolation valve 30.
    [0020] In general, a valve block according to the present invention has many advantages, besides the comfort of pressure reading for the user, it allows in particular to provide one or more high pressure gas outlets on the top of the valve block, that is to say the opposite of the gas source 20 with respect to the expansion system but also to improve the overall ergonomics of the valve block, which also tends to reduce the risk of error reading of pressure in particular, thanks to an increased flexibility of positioning of the elements subjected to high pressure, namely the pressure indicator device 7, such as a pressure gauge, but also other elements, such as pressure sensor, rupture disc ...
    [0021] An assembly according to the invention is particularly suitable for use in a medical environment, in particular for the distribution of any medical gas or gas mixture, in particular of oxygen, air, N 2 O 2, He / O 2, NO / nitrogen or other type .
