pression de volumes importants de gaz comprimé dans des réservoirs sous de fortes pressions pendant le remplissage des réservoirs, le stockage dans les réservoirs et le vidage des réservoirs. L'air comprimé ou tout autre gaz comprimé peut être stocké et transporté, ou bien utilisé pour faire fonctionner des turbines à air ou à gaz ou des moteurs à air comprimé pour des véhicules terrestres ou marin.  pressure of large volumes of compressed gas in tanks under high pressures during tank filling, storage in tanks and emptying tanks. Compressed air or other compressed gas may be stored and transported, or used to operate air or gas turbines or compressed air engines for land or marine vehicles.

Stocker de grands volumes de gaz comprimé est également intéressant pour un gaz comme l'hydrogène. On peut le transporter sous forme de gaz comprimé, sa température de liquéfaction étant trop basse et rendant difficile et onéreux un transport sous forme liquide.  Storing large volumes of compressed gas is also beneficial for a gas such as hydrogen. It can be transported in the form of a compressed gas, its liquefaction temperature being too low and making transport in liquid form difficult and expensive.

Des volumes importants de gaz comprimés sont également nécessaires pour les moteurs à air comprimé de véhicules terrestres ou marins, volumes qui garantissent une autonomie suffisante des véhicules. La présente invention détaille un procédé régulation de pression pendant le remplissage, le stockage et l'utilisation de grand volume d'air ou de tout autre gaz comprimé sous de fortes pressions. Il s'agit de réguler la pression des réservoirs de gaz d'un grand volume d'un ordre de grandeur jusqu'à 10000 (dix mille) m3 (mètres cubes) sous des pressions pouvant aller jusqu'à 1000 bars. Il n'existe pas de matériau avec lequel un réservoir constitué d'une seule enveloppe épaisse puisse supporter les contraintes générées par ces pressions pour ces volumes. On connaît suivant FR 2 582 071 - Al un procédé d'enceinte haute pression destiné à des pressions internes élevées, composée de plusieurs enceintes intermédiaires emboîtées les unes dans les autres et séparées par des intervalles remplis par des fluides intermédiaires soumis à des pressions intermédiaires comprises entre le pression interne et la pression extérieure, les pressions intermédiaires allant en diminuant de l'intérieur vers l'extérieur de l'enceinte, le tube extérieur pouvant être autofritté. Suivant l'invention, pour un réservoir, fabriqué suivant ce principe d'enceintes intermédiaires, en acier ou matériaux composites qui peuvent être de grande diffusion ou à haute performance, on remplit les différents volumes des différentes enceintes avec du gaz comprimé aux différentes pressions intermédiaires imposées par les résistances maximum que peuvent supporter chacune des enceintes. Pour minimiser les efforts à la surface du réservoir et répartir les efforts de manière homogène, le choix d'une forme sphérique pour le réservoir peut être préféré, mais toutes les surfaces fermées symétriques constituent naturellement un volume utilisable par la présente invention. Suivant l'invention, on garantit la montée et la tenue aux 15 pressions souhaitées dans chacune des enceintes. L'arrivée d'air se fait au travers d'un orifice qui traverse de manière étanche les enveloppes des différentes enceintes jusqu'à l'enceinte centrale. Si on appelle P1 la pression souhaitée de l'enceinte centrale, la pression du gaz dans 20 l'orifice d'arrivée est également de Pl. La régulation en pression est pilotée automatiquement par des soupapes. Ces soupapes garantissent que pour chaque enceinte, la différence de pression entre la face externe et la face interne reste inférieure ou égale à la pression maximale autorisée et 25 autorisent également le remplissage des différentes enceintes aux pressions souhaitées. Selon le schéma n 1 figurant en annexe, qui est une coupe transversale d'une enceinte sphérique constituée par 3 enceintes sphériques intermédiaires S1 , S2, S3 s'emboîtant les unes dans 30 les autres, les pressions dans les sphères sont respectivement Pl, P2, P3 avec Pl > P2 > P3. L'enceinte sphérique S3 a sa surface extérieure (4) à la pression extérieure. Les rayons des sphères sont respectivement R1, R2, R3 avec R3 > R2 > R1, les différences entre les rayons respectifs permettant les 35 emboîtements des sphères augmentées des renforts structuraux placés en surface. L'arrivée d'air se fait par l'intermédiaire d'un tuyau d'alimentation (5) fournissant du gaz à la pression P1. Ce tuyau d'alimentation (5) alimente directement en gaz à la pression Pl l'enceinte S1. Ce tuyau d'alimentation (5) alimente également en gaz à la pression Pl l'enceinte S2 par l'intermédiaire d'une vanne de remplissage (6). Ce tuyau d'alimentation (5) alimente enfin en gaz à la pression Pl l'enceinte S3 par l'intermédiaire d'une seconde vanne de remplissage (7). Ces vannes (6) et (7) sont des vannes actionnées soit mécaniquement par au moins un ressort, soit hydrauliquement par l'intermédiaire d'au moins 1 vérin, soit électriquement par l'intermédiaire d'au moins 1 électrovanne. La vanne (7) est tarée pour permettre le passage de l'air du tuyau d'alimentation (5) à la pression Pl jusqu'à l'enceinte S3 et stopper le passage de l'air dès que la pression dans l'enceinte S3 est supérieure à la pression souhaitée P3. La différence de pression à laquelle est soumise la face extérieure de l'enceinte S3 (4) est inférieure ou égale à (P3-Pextérieure). Pendant le remplissage des enceintes, la pression augmente. La vanne (6) est tarée pour permettre le passage de l'air du tuyau d'alimentation (5) à la pression Pl jusqu'à l'enceinte S2 et stopper le passage de l'air dès que la pression dans l'enceinte S2 est supérieure à la pression souhaitée P2. La différence de pression à laquelle est soumise la face extérieure de l'enceinte S2 (8) est inférieure ou égale à (P2-P3).  Large volumes of compressed gas are also needed for compressed air engines of land or marine vehicles, volumes which guarantee a sufficient autonomy of the vehicles. The present invention details a pressure control method during filling, storage and use of large volume of air or other compressed gas under high pressures. It is a question of regulating the pressure of gas tanks of a large volume of an order of magnitude up to 10000 (ten thousand) m3 (cubic meters) under pressures up to 1000 bars. There is no material with which a reservoir consisting of a single thick shell can withstand the stresses generated by these pressures for these volumes. According to FR 2 582 071 - A1, a high-pressure chamber method for high internal pressures, composed of a plurality of intermediate chambers fitted into each other and separated by intervals filled with intermediate fluids subjected to intermediate pressures included. between the internal pressure and the external pressure, the intermediate pressures decreasing from the inside towards the outside of the enclosure, the outer tube being able to be autofrited. According to the invention, for a tank, manufactured according to this principle of intermediate enclosures, made of steel or composite materials which can be of high diffusion or high performance, the different volumes of the different chambers are filled with compressed gas at different intermediate pressures. imposed by the maximum resistances that can support each speaker. To minimize the forces on the tank surface and evenly distribute the forces, the choice of a spherical shape for the tank may be preferred, but all symmetrical closed surfaces naturally constitute a volume usable by the present invention. According to the invention, the rise and hold is guaranteed at the desired pressures in each of the enclosures. The air supply is through an orifice that tightly crosses the envelopes of the various speakers to the central speaker. If the desired pressure of the central chamber is designated P1, the gas pressure in the inlet port is also P1. The pressure control is automatically controlled by valves. These valves ensure that for each chamber, the pressure difference between the outer face and the inner face remains less than or equal to the maximum allowed pressure and 25 also allow the filling of the various speakers to the desired pressures. According to the diagram No. 1 in the appendix, which is a cross section of a spherical enclosure consisting of three intermediate spherical enclosures S1, S2, S3 fitting into each other, the pressures in the spheres are respectively Pl, P2 , P3 with P1> P2> P3. The spherical enclosure S3 has its outer surface (4) at the external pressure. The spherical radii are respectively R 1, R 2, R 3 with R 3> R 2> R 1, the differences between the respective rays permitting the spheres of the spheres to be increased by structural reinforcements placed on the surface. The air supply is via a supply pipe (5) supplying gas to the pressure P1. This supply pipe (5) directly supplies gas to the pressure P1 enclosure S1. This supply pipe (5) also supplies gas to the pressure P1 the enclosure S2 via a filling valve (6). This supply pipe (5) finally supplies gas to the pressure P1 the chamber S3 via a second filling valve (7). These valves (6) and (7) are valves actuated either mechanically by at least one spring, or hydraulically via at least 1 cylinder, or electrically via at least 1 solenoid valve. The valve (7) is calibrated to allow the passage of air from the supply pipe (5) to the pressure Pl to the enclosure S3 and stop the passage of air as soon as the pressure in the enclosure S3 is greater than the desired pressure P3. The pressure difference to which the outer face of the enclosure S3 (4) is subjected is less than or equal to (P3-outside). While the speakers are charging, the pressure increases. The valve (6) is calibrated to allow the passage of air from the supply pipe (5) to the pressure Pl to the enclosure S2 and stop the passage of air as soon as the pressure in the enclosure S2 is greater than the desired pressure P2. The pressure difference to which the outer face of the enclosure S2 (8) is subjected is less than or equal to (P2-P3).

Dès que la pression dans l'enceinte S1 atteint la pression Pl, l'alimentation de l'arrivée d'air est coupée. La différence de pression à laquelle est soumise la face extérieure de l'enceinte S1 (9) est inférieure ou égale à (Pl-P2) et les enceintes sont alors aux pressions respectives souhaitées Pl, P2 et P3. Le remplissage de l'enceinte est donc fait graduellement et de manière à ce que chacune des enceintes soit soumise à une différence de pression entre sa surface extérieure et sa surface intérieure toujours inférieure ou égale à la pression imposée par les résistances maximum que peut supporter cette enceinte. Les enceintes sont donc régulées en pression pendant le remplissage Pour garantir la tenue en pression de chacune des enceintes, on place sur chacune de ces enceintes au moins une vanne de sécurité Vs qui permet le passage de l'air de chacune des enceintes vers l'enceinte directement extérieure et adjacente. Ainsi, une vanne Vsl (10) permet le passage du gaz depuis l'enceinte S1 dans l'enceinte S2. Une vanne Vs2 (11) permet le passage du gaz depuis l'enceinte S2 dans l'enceinte S3 et une vanne Vs3 (12) permet le passage du gaz depuis l'enceinte S3 dans l'enceinte extérieure.  As soon as the pressure in the chamber S1 reaches the pressure P1, the supply of the air supply is cut off. The pressure difference to which the outer face of the enclosure S1 (9) is subjected is less than or equal to (P1-P2) and the enclosures are then at the respective desired pressures P1, P2 and P3. The filling of the enclosure is therefore done gradually and so that each of the speakers is subjected to a pressure difference between its outer surface and its inner surface always less than or equal to the pressure imposed by the maximum resistance that can support this pregnant. The speakers are therefore regulated in pressure during filling To ensure the pressure resistance of each of the speakers, is placed on each of these speakers at least one safety valve Vs that allows the passage of air from each of the speakers to the directly external and adjacent enclosure. Thus, a valve Vsl (10) allows the passage of gas from the enclosure S1 in the enclosure S2. A valve Vs2 (11) allows the passage of gas from the enclosure S2 in the enclosure S3 and a valve Vs3 (12) allows the passage of gas from the enclosure S3 in the outer enclosure.

Ces vannes sont tarées pour autoriser le passage du gaz décrit dès que la pression dans chacune des enceintes est supérieure à la pression souhaitée. Ainsi, une surpression API dans l'enceinte S1 par rapport à la pression de consigne Pl va faire actionner l'ensemble de vanne de sécurité Vsl (10) et laisser passer le gaz de l'enceinte S1 à l'enceinte S2. Ceci va générer une surpression àP2 dans l'enceinte S2 par rapport à la pression de consigne P2 et ainsi faire actionner la vanne de sécurité Vs2 (11). Un comportement analogue des vannes de sécurité situées sur toutes les enceintes permettra une évacuation des surpressions éventuelles dans chacune des enceintes. Les enceintes sont donc régulées en pression pendant le remplissage et pendant le stockage. Pour le vidage des enceintes, le gaz compris dans l'enceinte centrale S1 est d'abord utilisé. Pour éviter que les enceintes soient soumises à des différences de pression supérieures à la pression maximum autorisée, les enceintes autres que l'enceinte centrale S1 sont également vidées à l'exception de l'enceinte externe. Pour vider ces enceintes internes, on utilise dans chacune des enceintes internes comprises entre l'enceinte centrale et l'enceinte la plus extérieure au moins une vanne de vidage Vv (13). Cette vanne de vidage autorise le passage du gaz entre cette enceinte et le tuyau d'évacuation (5) qui est pris identique au tuyau d'alimentation (5). Dès que la pression dans l'enceinte S1 a décrut jusqu'à la pression P2 de l'enceinte S2, la vanne Vv (13) s'ouvre et autorise l'enceinte S2 à se vider dans le tuyau d'évacuation. Les enceintes Si et S2 vont continuer à se vider selon la demande jusqu'à avoir une pression interne supérieure ou égale à la pression P3 de l'enceinte S3.  These valves are calibrated to allow the passage of the described gas as soon as the pressure in each of the speakers is greater than the desired pressure. Thus, an overpressure API in the chamber S1 with respect to the set pressure P1 will actuate the safety valve assembly Vsl (10) and let the gas from the enclosure S1 to the enclosure S2. This will generate an overpressure P2 in the chamber S2 with respect to the set pressure P2 and thus actuate the safety valve Vs2 (11). A similar behavior of the safety valves located on all the speakers will allow evacuation of the possible overpressures in each of the enclosures. The speakers are therefore regulated in pressure during filling and during storage. For the emptying of the speakers, the gas included in the central speaker S1 is first used. To prevent speakers from experiencing pressure differences greater than the maximum allowable pressure, speakers other than center speaker S1 are also dumped except for the external speaker. To empty these internal speakers, is used in each of the internal speakers between the central speaker and the outermost enclosure at least one Vv drain valve (13). This emptying valve allows the passage of gas between this chamber and the discharge pipe (5) which is taken identical to the supply pipe (5). As soon as the pressure in the chamber S1 has decreased to the pressure P2 of the chamber S2, the valve Vv (13) opens and allows the chamber S2 to empty into the drain pipe. The speakers Si and S2 will continue to empty according to the demand until an internal pressure greater than or equal to the pressure P3 of the enclosure S3.

Les enceintes sont donc régulées en pression pendant le remplissage, pendant le stockage et pendant le vidage.  The speakers are therefore regulated under pressure during filling, during storage and during emptying.
