Definitions

  • the invention relates generally to the field of fluid storage and delivery and more particularly to devices and systems for the automatic delivery and shutoff of fluids during the process of filling pressure containers.
  • Sealed pressure containers such as approved by the U.S. Department of Transportation (DOT) are gaining popularity as vessels for storing and delivering fluids.
  • Some of the advantages gained by using pressure containers include enhanced health and safety since DOT pressure containers resist slitting and leakage, decreased environmental impact due to a lower probability of fluid being inadvertently released from sealed pressure container, more efficient fluid transfer capabilities between the container and the destination of the fluid (e.g. an automobile or other machine), and lower costs due to reusability of the pressure containers.
  • a propellant gas such as nitrogen or carbon dioxide
  • FIGURE 1 is a perspective view of the device of the invention connected to a pressure container adapted to be filled with fluid.
  • FIGURE 2 is a side view of the device, with the valve in the open position.
  • FIGURE 3 is a side view of the device, with the valve in the closed position.
  • the device 10 of the invention includes a memory unit 12.
  • Memory unit 12 includes a sealed pressure vessel 14 having a predetermined interior volume 16, and preferably with a small and predetermined amount of liquid 18 (e.g. oil) contained therein. The reason for this is that liquids are less likely to leak from hydraulic cylinders than are gases, are much less compressible under pressure, and thus are far more reliable.
  • Memory unit 12 has a gas inlet valve 20 to permit gas to be introduced and pressurize the interior volume 16 and fluid 18 contained in memory unit 12.
  • a pressure gauge 22 is in communication with memory unit 12. Pressure gauge 22 indicates the “open” and “close” pressure, as will be discussed below.
  • a small fluid tube 24 is in fluid connection between the bottom of memory unit 12 and a hydraulic cylinder 26 at a right side 28. Pressure gauge 22 provides a visual indication of the pressures at which fluid will flow into sealed pressure container 58 (open) and the pressures at which fluid flow will stopped (close), indicating sealed pressure container 58 is full.
  • the pressurizing gas is preferably an inert gas.
  • Hydraulic cylinder 26 has a fluid tight piston 30 with a push rod 32 located therein.
  • a second hydraulic fluid tube 34 is connected to hydraulic cylinder 26 at hydraulic cylinder's left side 36.
  • Second hydraulic fluid tube 34 connects to and is in fluid communication with a downstream fluid junction means, for example, in the form of a T- fitting 38.
  • Push rod 32 has a first engagement means located at its distal end, such as gear rack 40. Alternately, other engagement means can be provided.
  • Gear rack 40 rides on a geared sprocket 42.
  • Geared sprocket 42 is connected to and is adapted to open and close a fluid valve 44 (such as a ball valve).
  • valve 44 has a fluid/air inlet side 46, and a fluid outlet side 48. Fluid to be fed into a sealed pressure container 58 to be filled is fed to fluid/air inlet side 46 of valve 44 via fluid supply line 50. Fluid supply line 50 is in turn connected to a larger source of fluid, e.g. a tanker truck supplying the fluid via pumps (not shown.) Fluid/air inlet side 46 and outlet sides 48 preferably have reducers 52 and 54, respectively, to reduce fluid pressure fluctuation and spurts through valve 44. Fluid travels through valve 44 and exits outlet side 48 and enters T-fitting 38. As best shown in Fig. 1, a fluid fill hose 56 is adapted to carry fluid to sealed pressure container 58 to be filled.
  • a pressure valve 60 can be positioned on T-fitting 38 to monitor the fluid pressure in T-fitting 38 (and thus the fluid pressure in sealed pressure container 58.)
  • An additional safety feature is provided as follows.
  • a locking mechanism 62 can preferably be provided to automatically maintain valve 44 in a closed position when sealed pressure container 58 is filled with fluid.
  • One such locking mechanism 62 is shown, and comprises a pivoted catch arm 64 with a locking head 66, wherein head 66 slideably rides on and does not engage with gear rack 40 until gear rack 40 is positioned to the right, thereby turning sprocket 42 clockwise (and thus closing valve 44.) At this position, head 64 will be resting behind gear rack 40 (or on a locking point of gear rack 40, not shown) and thus prevent gear rack 40 from further turning geared sprocket 42, and thus not allowing fluid valve 44 from being inadvertently opened, as best shown in Figure 3.
  • the device 10 functions as follows. As fluid enters the system from fluid/area inlet side 46, and travels through valve 44, and into the fluid egress side 48, there will be a pressure drop due to constriction of the inner diameter of the tubing and reduced size of the interior diameter of valve 44.
  • fluid fill hose 56 connects to a sealed pressure container 58 via hose 68.
  • fluid fill hose 56 can have a hydraulic fitting 70 for connection to a fluid filling fitting 70 connected to hose 68.
  • Fluid filling fitting 70 preferably incorporates a device to prevent any fluid or volume of the blanket of propellant gas in sealed pressure container 58 from escaping.
  • Sealed pressure container 58 is adapted for holding a liquid, such as hydraulic or motor oil, and a blanket of pressurized propellant gas, preferably an inert gas, such as nitrogen.
  • the pressure of the propellant gas in sealed pressure container 58 will increase due to the decreased gas volume area available.
  • sealed pressure container 58 when empty, will be charged with about 20 P.S.I, of nitrogen gas.
  • the nitrogen gas pressure might jump to about 80 to a 100 P.S.I.
  • This pressure is experienced in the fluid in T-fitting 38 and second hydraulic fluid tube 34 connected to the left side 36 of hydraulic cylinder 26.
  • This new invention represents an important improvement to the art because it allows sealed pressure fluid containers under propellant gas blanket to be refilled in a safe and effective manner from high pressure fluid sources of fluid, such as tanks of fluid fed under higher pressure pulses, and automatically shuts off the fluid flow when the container is full.

Abstract

Cette invention se rapporte à un dispositif de réapprovisionnement automatique pour récipient à fluide (10). A cet effet, on prévoit un récipient sous pression (12) qui est chargé d'un gaz sous pression et d'un fluide, et un cylindre hydraulique (26) qui délimite un volume intérieur et dans lequel est disposé un piston (30) auquel est fixé un arbre d'entraînement (32) qui s'étend hors du cylindre hydraulique (26). Sur l'arbre d'entraînement (32) est disposé un engrenage à crémaillère (40). Le cylindre hydraulique (26) comporte au niveau d'une première et d'une seconde extrémité des entrées de fluide hydraulique (28, 36). Un conduit à fluide (24) relie le récipient sous pression (12) et une première entrée de fluide hydraulique (28). Une valve (44) possède une entrée de fluide (46) et une sortie (48). Un pignon denté (42) est monté sur la valve (44) et peut être actionné pour ouvrir et fermer la valve (44). L'engrenage à crémaillère (40) disposé sur l'arbre d'entraînement (32) vient se placer en prise avec le pignon denté (42) et l'actionne. Un tuyau d'amenée de fluide (50) est raccordé à l'entrée de fluide (46) et transporte le fluide à partir d'une source de fluide à travers la valve (44). Une jonction fluidique (38) est placée en communication fluidique avec une sortie de fluide (48) de la valve (44). Un second tube à fluide (34) raccorde la jonction fluidique (38) et la seconde entrée de fluide hydraulique (36). Un tube de remplissage de fluide (56) raccorde la jonction fluidique (38) à un récipient à fluide (58) devant être réapprovisionné.
