摘要:
Device for feeding fuel gas to an application (6), the device comprising at least one fuel gas bottle (1) furnished with a tap (2), and a bleed‑off apparatus (4, 13) comprising an electronic logic unit (9) and a bleed‑off outlet (4) selectively connectable to the tap (2), the bleed‑off outlet (4) being linked (5) fluidically to an application (6) receiving the fuel gas originating from the bottle (1), the tap (2) comprising an electronic manometer (3) for measuring the pressure in the bottle (1), the electronic manometer (3) being devoid of battery and comprising an inductive member (7) for wirelessly transmitting to the electronic logic unit (9) information relating to the measured pressure, characterized in that the bleed‑off apparatus (4, 13) also comprises an inductive member (8) powered electrically by the electronic logic unit (9) and in that, when the bleed‑off outlet (4) is connected up to the tap (2), the inductive member (8) of the bleed‑off outlet (4) is situated in a manner adjacent to the inductive member (7) of the manometer (3) so as to ensure electrical power supply of the manometer (3) by inductive coupling.
摘要:
A method for filling tanks (1) with pressurised gas via a filling station (100) comprising several storage containers (2, 3, 4, 15, 16) and a fluid circuit (5) for transferring the gas from the containers to the tanks (1), the circuit (5) comprising a first end to which the containers (2, 3, 4, 15, 16) are linked in parallel and a second end provided with a transfer line (6) intended to be connected to the tank(s) (1) to be filled, the circuit (5) comprising, arranged in series between the first end and the second end, a first isolation valve (7), a flow or pressure regulation member (8), and a second isolation valve (11), the method comprising filling a first tank (1), characterised in that, on completion of the filling of the first tank (1) and before filling a second tank, the first (7) and second (11) isolation valves are closed to trap a supply of pressurised gas in the circuit (5) between said two valves (7, 11) and in that the supply of gas is used to refill at least one of the containers.
摘要:
The invention relates to a tap including a body (3), which is provided with a gas inlet (22) that is to be connected to the storage space of a container (2), a bleed-off circuit (5), and including a downstream end (25, 22) that is to be selectively fluidly connected to a bleed-off member (6), the bleed-off circuit (5) including an isolation valve (8) and a pressure-release member, the tap (1) also including a member (18) for manually controlling the movement of the selectively movable isolation valve into a first position and into a second position, wherein, in the first position thereof, the control member (18) places the isolation valve (8) in a position for opening the bleed-off circuit (5) and, in the second position thereof, the control member (18) places the isolation valve (8) in a position for closing the bleed-off circuit (5), characterized in that the tap (1) further includes a circuit (10) for selectively controlling the movement of the isolation valve (8) into the first position thereof for opening the bleed-off circuit (5), the control circuit (10) including a first end connected to the valve (8), and a second end (100) that can be selectively coupled to an actuator (11) of a gas bleed-off member (6), in order to selectively electrically control the movement of the valve (8) into the position for opening the bleed-off circuit (5).
摘要:
Pile à combustible comprenant une pluralité de cellules adjacentes formant un empilement (1) de cellules, un dispositif de refroidissement dudit empilement (1) de cellules par échange thermique forcé avec un gaz caloporteur tel que l'air au moyen d'au moins un générateur (2) d'un flux gazeux selon un axe (A) d'écoulement, caractérisée en ce qu 'elle comporte au moins un organe redresseur (3) de flux gazeux disposé entre l'empilement (1) de cellules et le générateur (2), l'organe redresseur (3) comprenant au moins une pale (13) statique conformée pour diminuer l'hétérogénéité du débit du flux gazeux issu du générateur (2) selon une direction sensiblement perpendiculaire à l'axe (A) du flux avant son arrivée à l'empilement (1).
摘要:
The invention relates to a residual pressure valve device comprising a shut-off member (1) that is able to move in the body (9) relative to a seat (2), a return member (5) that urges the shut-off member (1) by default towards the seat (2), the shut-off member (1) comprising an internal duct (6) having a first end in communication with the gas inlet (3) and a second end that leads, via a calibrated orifice (8), into a control chamber (7) that is closed by the shut-off member (1) such that, when the gas pressure in the control chamber (7) reaches a predetermined threshold, this pressure causes the shut-off member (1) to move away from the seat (2), the body of the shut-off member (1) comprising a first portion (11) that forms a male element which is able to move in translation in a female passage of the body (9) with a predetermined fit forming a restriction ensuring partial and progressive opening of the passage for the gas between the inlet (3) and the outlet (4).
