Definitions

  • a system for the storage of a flowable mass such as a liquid or a pulverulent solid, includes two storage units each with a closed vessel provided with a pair of three-way valves which are controlled by respective actuating levers.
  • the two levers may be interconnected for joint swinging into a filling position, in which a supply of flowable mass communicates with a first conduit of an associated vessel while a second conduit thereof is vented, or into an emptying position, in which a source of high-pressure fluid communicates with the second conduit for expelling the contents of the vessel through the first conduit.
  • the first lever may be placed in its filling position while the second lever is in its emptying position whereby the contents of the associated vessel can be transferred to the vessel of another storage unit through the supply conduit common to both units.
  • My present invention relates to a system for the storing and distribution, under pressure, of various gaseous, liquid or pulverulent products, wherein a closed storage vessel or tank is connected to a source of external driving fluid under pressure capable of expelling all or part of the contents of the storage vessel.
  • the products stored can be subjected to pressure by a gas which is inert with respect to the product in question. It is thus possible, for example, to use nitrogen or carbon dioxide. Similarly, for other applications, use can be made of an auxiliary liquid which is enert with respect to the product to be transferred.
  • the primary object of the invention is to provide a system of the aforementioned type which, by reason of its nature and design, will be of simple construction and easy to handle, in addition to satisfying the requirements of safety.
  • a plurality of storage units for a flowable mass capable of displacement by a high-pressure fluid capable of displacement by a high-pressure fluid, this mass being deliverable to a closed vessel in each unit through a supply conduit common to the several units.
  • Each unit is connectable through a common high-pressure conduit to a source of driving fluid and is further provided with a discharge conduit for the flowable mass, a venting conduit for the driving fluid and first and second conduits leading to its vessel.
  • a first three-way valve or cock is controlled by a first actuator, such as a lever, for alternately assuming a filling position and an emptying position respectively connecting the first conduit to the supply conduit and to the discharge conduit; a second three-way valve or cock is similarly controlled by a second actuator for alternately connecting the second conduit to the venting conduit in a filling position and to the high-pressure conduit in an emptying position.
  • a first actuator such as a lever
  • a second three-way valve or cock is similarly controlled by a second actuator for alternately connecting the second conduit to the venting conduit in a filling position and to the high-pressure conduit in an emptying position.
  • first actuator of a unit If the first actuator of a unit is in its filling position while the second actuator of the same unit is in its emptying position, a circuit is established from the source of driving fluid through the vessel of that unit to the common supply conduit whereby the contents of this vessel can be transferred to the vessel of another unit having its actuators in filling position.
  • the two actuators of each unit are provided with a detachable linkage for selectively interconnecting same.
  • conduit communicating with the second cock and terminating near the top of the tank enters this latter at a level beneath the lower end of an additional conduit provided with a conventional pressurerelief valve.
  • This simple arrangement constitutes a safety device which minimizes the occurrence of fluid shocks in the conduits at the end of the filling operation, i.e., when the level of the product to be stored reaches the lower end of the conduit through which the high pressure fluid is evacuated.
  • FIGS. 1 and 2 are operating diagrams showing one storage unit of a system in accordance with the invention in the filling phase and in the discharge phase, respectively;
  • FIG. 3 is an operating diagram showing thedifferent elements of the system during the transfer of the contents of the storage unit of FIGS. 1 and 2 to another storage unit SPECIFIC DESCRIPTION
  • the system shown in the drawing two closed vessels tanks which may or maynot be of the underground type served by a common supply station 3 and forming part of respective storage units, generally designated 4 and 4'.
  • the two units being identical, I shall describe only unit 4 in greater detail.
  • a first three-way cock 5 is capable of placing a conduit 7, whose lower end terminates in the vicinity of the bottom of the tank 2, in communication either with a feed conduit 8 for the fluid to be stored or with a discharge conduit 9.
  • a second cock 6 is capable of placing a conduit 10, whose lower end opens into the tank 2 near the top thereof, in communication either with an evacuation conduit 12 for a high-pressure driving fluid or with a conduit 13 connected to a source of that fluid, such as a gas reservoir 14.
  • the conduit 13 contains in successive sion, starting from the gas reservoir 14, a stop cock IS, a high-pressure manometer 16, a relief valve 17, a calibrated nozzle 18, and a low-pressure stage consisting of a manometer 19, a safety valve 20 and an isolating gate 21.
  • the conduit 13 also contains, upstream of the cock 6, a check valve 22.
  • the conduit 8 conveying the florable mass from an inlet port 23 at the supply station to the first cock 5, contains an isolating gate 24, a check valve 25 and a discharge valve 26. Finally, a conduit 27, whose lower part terminates in the tank 2, contains a safety valve 28 capable of opening in the event of development of excess pressure in the tank.
  • the three-way cocks 5 and 6, which in principle could be sliding or rotating valves are arranged so that their actuating means can be temporarily coupled to gether for specific operations.
  • these cocks are of the rotatable type and are arranged back-to-back so that the axes of rotation of their rotatable elements are aligned.
  • the rotatable element of each of these two cocks is rotationally integral with one of the ends of a respective lever, 5a and 6a whose other end is detachably connected to a common operating handle 29.
  • conduit 27 penetrates for to a certain distance d into the neck of the tank 2 while the conduit 10 is for a greater distance D.
  • the detachable connection 29 between the two levers 5a and 6a makes it possible to disconnect them from each other, particularly in order to enable the liquid contained in one storage unit (e.g. tank 2) to be transferred to another storage unit (e.g. tank 2') of the system.
  • one storage unit e.g. tank 2
  • another storage unit e.g. tank 2'
  • this installation can be used for the storage of any liquid and particularly for that of fuels and of dangerous or toxic products.
  • a system for the storage of a flowable mass capable of displacement by a high-pressure driving fluid comprising:
  • a plurality of storage units for said flowable mass each including a closed vessel with a first conduit and a second conduit;
  • a source of driving fluid provided with a highpressure conduit for each of said units
  • first three-way valve means at each of said units for connecting said first conduit thereof to said supply conduit in a filling position and to said discharge conduit in an emptying position;
