- FIG. 4 is a front view of the same actuator in an open position of the valve flap and non-adjustment of an output flow
- FIG. 5 is a front view of the same actuating member in a opening position of the valve of the valve and adjustment of an output flow
- valve 1 shown in Figure 1 comprises a body 2 connected to a gas outlet port 3 G of a gas bottle 4.
- a gas removal circuit C G is formed in the body 2 to connect a gas inlet 11 connected to the inside of the bottle 4 to at least one outlet 5, 25 of gas release.
- a filter 12 may be provided downstream of the inlet 11. Downstream of the filter 12, the circuit C is subdivided into a plurality of conduits.
- a first conduit 13 communicates with a manometer 14 mounted on the body 2.
- a second conduit 15 is connected to a filling socket 16.
- a third conduit 17 or release channel conveys the gas direction of one or more outlets 5, 25.
- the circuit C release conduit 17 comprises a safety valve 31 intended to avoid subjecting the downstream elements to significant pressure if accidental leakage occurred.
- the circuit C Downstream of the safety valve 31, the circuit C comprises a first expander 18, called a "high pressure expansion valve", designed to relax the high-pressure gas P1 of the bottle 4, for example between 200 bar and 300 bar or more. at a lower intermediate pressure P2, for example between 10 bars and 15 bars approximately.
- a high pressure expansion valve designed to relax the high-pressure gas P1 of the bottle 4, for example between 200 bar and 300 bar or more.
- a lower intermediate pressure P2 for example between 10 bars and 15 bars approximately.
- the circuit C Downstream of the high pressure regulator 18, the circuit C includes a valve 6 opening / closing to allow or not the release of gas at an outlet 5, 25 of the valve 1. Due to the presence of this high pressure regulator 18, all the elements situated downstream of the valve 6, including the movable elements and the seals present in the circuit C for proper operation of the valve, are, according to the invention, subjected to a relatively low pressure, less than or equal to at P2. These elements are therefore subjected to low stresses in both pressure and friction force and are thus not subject to significant wear such as can be found for valves of the prior art.
- the valve 6 is movable, for example in translation, between a closed position 20 of the circuit C and an open position 21 of the circuit C. In the example of FIG. 1, the circuit C is closed, the closed position of the valve 6 prevents the flow of gas in the circuit C between the upstream portion 28 and the downstream portion 29 to the valve 6.
- the valve 1 may also include a low pressure regulator 19 located downstream of the valve 6, that is to say between the valve 6 and at least one outlet 5, 25 of the circuit C.
- This low pressure regulator allows a flow of gas downstream at a constant pressure P3, the pressure P3 being, for example, between 1 and 5 bar.
- the elements located downstream of the low pressure regulator 19 are no longer subject to pressure fluctuations.
- the constant low pressure obtained makes it possible to obtain stable flow rates at the outlets 5 and 25 of the tap, which greatly facilitates the use of such a faucet and increases its safety as well as that of patients or users.
- the valve 1 comprises at least one adjusting element 23 of the gas release rate G admitted to an outlet 5, and a single actuating member 9 able to control both the valve 6 and the flow control element 23.
- the actuating member 9 comprises for example a flywheel, mounted movably relative to the body 2 is adapted to control during translational movements the displacement of the valve 6 between its open positions 21 and closure 20.
- the user has imposed a translational movement towards the body 2, to the actuating member 9.
- the actuating member 9 is able to move the valve 6 to an opening position 21, by contact between one end 22 of the valve 6 and the actuating member 9.
- the opening 21 position of the valve 6 allows the release of the gas in the circuit C to an outlet 5, 25.
- the valve 6 is slidably mounted and biased by at least one biasing member 27 towards its closed position 20. An end 22 of the valve member 6 is held in contact with the actuating member 9 by the biasing member 27.
- the biasing member 27 applies a force on the actuating member 9 for the usser translation outwardly of the body 2 to leave the valve 6 in the closed position 20 and thus ensure the default shutter of the circuit C.
- This shutter by default is performed when the user has not imposed of translation movement, towards the body 2, to the actuating member 9.
- the actuating member 9 is also able to control, during its rotation, the adjusting element 23 of the gas outlet flow G.
- the valve 1 comprises at least a first flow outlet 5 located downstream of the flow control element 23.
- the valve 1 comprises at least a second so-called pressure outlet 25 located upstream of the flow control element 23 and downstream of the low pressure regulator 19.
- the second outlet 25 may comprise a valve 26 for its opening and its suitable closure. to cooperate for example with a connection of a chosen device. So the user is free to have this second outlet 25 to release gas G at low pressure to a device of its choice.
- the adjustment element 23 comprises a portion 8, for example a disc, integral in rotation with the actuating member 9, disposed between the valve 6 and at least one outlet 5 called flow.
- the disc comprises a plurality of orifices of different diameters respectively corresponding to predefined flow rates.
- the rotation of the actuating member 9 makes it possible to fix by cooperation of the portion 8 with the adjustment element 23, one of the orifices opposite one end 30 of the gas release circuit C.
- the flow is regulated by the diameter of the orifice chosen.
- the above mechanism has a considerable advantage over the prior art. Indeed, to open the circuit C and thus allow the free flow of gas G necessary for its withdrawal, the user has a very small effort and very easy to implement to produce: it suffices to press on the actuating member 9 causing a translational movement causing the displacement of the valve 6 to its open position 21. Then, a determined rotation locks the open position of the valve 6.
- the user can therefore adjust the gas output flow rate that he desires, available at the so-called flow outlet, by a simple additional rotation of the actuating member 9.
- the risk of errors as to the opening or closing of the circuit C is very small.
- the user is assured that the circuit C is open when he regulates the flow and in the same way it is ensured that the circuit C is closed when the valve 6 is in the closed position.
- a locking member 10 such as an abutment system, blocks the rotation of said actuating member 9 so that the only possible movement for the user is a translational movement of the actuating member 9 to the body 2.
- the circuit C is open because the valve 6 has been driven into its open position 21 by the translation of the actuating member 9 in contact with the end 22 of the valve 6.
- the rotation of the actuating member 9 is then released, which allowed, in Figure 4, the user to rotate the actuating member 9 by a determined first angle ⁇ , allowing it, for example, to use the so-called pressure outlet 25 without having to adjust the gas outlet flow rate G.
- the rotation of a first angle ⁇ prevents the return to the closed position 20 of the valve 6, since the translation of the valve 6 is blocked by the locking member 10 for example a stop.
- the user has chosen a flow rate and has therefore imposed an additional rotational movement on the actuating member 9 so that one of the flow control orifices is opposite a end 30 of the gas release circuit G.
- the flow rate is adjusted by the diameter of the orifice chosen, the actuating member 9 is always locked in translation in the open position of the valve 6.
- the flow positions selected are preferably marked by hard or stable points, for example a ball and spring means 7 contained either in the body 2 or in the adjusting member 23 and cooperating with housings on the actuating member 9.
- the user unlocks the actuating member 9 by imposing a sufficient force to drive it in rotation and thus choose to place another orifice of different diameter vis-à-vis one end 30 of the gas release circuit G.
- Alphanumeric references are preferably provided on the body 2 and / or the actuator 9 to signal the selected flow rate (0: open without flow, 1: first flow, 2: second flow, etc ...) -
- a valve 1 according to the invention is shown schematically by a dashed rectangle in a position protected by a cap or a protective housing 40 itself schematically in dotted lines.
- the valve shown in Figure 6 differs from that described above in that the actuating member 9 is located at the upper part of the body 2 of the valve.
- the actuating member protrudes above the end 41 of the cap or the protective casing 40.
- the end 42 of the actuating member 9 is at least partly substantially in the same plane as that of the upper end 41 40.
- Alphanumeric markings may be present on the cap or the protective casing 40 as well as on the actuating member 9, in order to indicate the different positions of the tap (opening, closing, selected flow rate).
- valve 1 is protected by another cap or protective housing 40.
- the actuating member 9 is in a position of removal maximum of the upper end 41 of the protective cap 40.
- the end 43 of the actuating member 9 is very close, for example almost in contact, the end 41 of the protective cap 40.
- This embodiment of the invention also provides the advantage of allowing the introduction, in addition to the alphanumeric markers already mentioned above, a color code for a better visualization of the valve opening / closing positions.
- connection zone 44 between the actuating member 9 and the cap or the protective casing 40 appears predominantly of a certain color when the valve 1 is in the closed position F and another color when the Valve 1 is in the open position O.
- the color of the alphanumeric marks corresponding to the different opening positions O of the valve 1, closing F of the valve 1 and flow rate chosen can also vary in the same way.
- the proposed solution therefore defines an ergonomics to clearly view the open position of the valve 1 clearly and visible from afar. This last point makes it possible to avoid the risks of involuntary maneuvers of the tap 1, in fact if there is a change of position of the tap 1, the user will be visually well informed.
