Definitions

  • This invention relates vto apparatus for storing fluid under pressure and has for its main object the provision f an improved form of apparatus for storing fluid at high pressure or at two or more different pressures.
  • a further object is to provide a durable and reliable apparatus for storing fluid, such as air, under pressure, which apparatus is less expensive to install than t-he devices now in common use.
  • a further object is to provide an apparatus of the above described character which greatly conserves the space necessary for installations of this character.
  • a further object is to provide in a device for storing fluid at high pressure or at two or more different pressures, an automatic pressure regulation whereby the stored fluid is maintained at a constant predetermined pressure in the apparatus and whereby a constant predetermined difference may-be maintained between the fiuids stored at different ly or wholly within a reservoir adapted tocontain fluid at a relativel low pressure.
  • the walls of each igh pressure reservoir which lie within the low pressure reservoir are subjected only to the difference of fluid pressure between the two reservoirs and thus need not be of such strength as has hitherto been necessary.
  • the invention is particularly applicable to apparatus for storing fluid at two or more different pressures -in which all the reservoirs contain the same fluid, for example compressed air, for use in the starting and operation of the engines of a motor ship.
  • an automatic pressure reducing valve may be provided between the high and a low pressure reservoirs so as to revent the difference between the high an low pressures exceeding a predetermined limit and so as to maintain a substantially constant difference between these pressures.
  • This valve is conveniently disposed outside the l0w.pres sure reservoir and connected thereto and to ⁇ the high pressure reservoir by suitable pipes or thelike so as to facilitate inspection and adjustment fo the valve.
  • a similar arrangement may also be employed where different fluids are contained in the two reservoirs, the pressure reducing'valve in this case being adapted to open only in case of emergency, soy as to act as a safety valve, and not being operative for slight pressure variations-such as might occur in the normal working of the apparatus.
  • the high and-low pressure reservoirs may be provided with a safety valve adapted to, open so as to permit escape of iuidv to the latmosphere when the pressure therein exceeds a predetermined limit.
  • this valve is convenientl so setthat when the maximum' pressure di ference between the two reservoirs isexceeded the valve will lift and allow fluid to ass from the inner to the outer reservoir.
  • T us when charging, assuming both reservoirs to be empty,.the compressor or the like will deliver fluid to the inner reservoir until the" pressure therein reaches the same value as the maximum pressure difference at which the two reservoirsare designed to operate.
  • the relief valve will then open so as to deliver the surplus Huid into the outer reservoir so that the pressures, in thetwo reservoirs will then rise simultaneousl while maintaining a constant pressure iierence between them.
  • the same pressure iierence will be maintained since when the'pressure in the outer reservoir drops due to Huid being drawn oi therefrom the relief valve between the two l reservoirs will open and permit some of the fluid to kescape from the inner reservoir to the outer reservoir until the desired pressure difference is again established.
  • a valve may be provided adapted to establish communication between the reservoirs when the ressure in the low ressure reservoir drops low a. certain pre etermined value.
  • the communicating valve may be controlled by a spring-controlled diaphragm or the like subjected to the pressure in the low pressure reservoir. lVith such an arrangement, however, if, as is preferable, a valve of comparatively large size is employed, the
  • valve is convenient-ly not directly controlled by the pressure in the low 'pressure reservoir but is '45 connected to a piston adapted to be acted upon bv high pressure fluid delivered through a subsidiary relay va lve which is of relatively small size and is connected to av spring-con- 56 trolled diaphragm or the like subjected to the pressure in the low pressure reservoir.
  • One side of the piston controlling the main valve is convenientlysubje'cted to the pressure in the low ressure'reservoir, a small leak being provided) through the piston wherebv when the high pressure fluid ceases to be delivered, behind the piston by the relay valve, the pressure on the two sides of the piston will auttunatically become equal and the valveV controlled thereby will be closed bv a spring or the like.
  • the invention may be applied to apparatus in which fluid is stored at more than two pressures, and in this case the reservoirs may apparatus employing one system JAof' reliefvalves,

  • Figurer?) is a diagrammatic View of an' alternative system of relief valves which may be employed.
  • the low pressure ⁇ reservoir is in the form of a cylindrical shell 1() built up from a series of steel plates and closed at its ends by suitable curved end caps 11 and 12.
  • a high pressure reservoir 15 which is built up from metal plates in a similar manner to the low pressure reservoir 10 and is of such dimensions yas to leave the desired space for the low pressure air between it-s walls and those of-the low pressure reservoir 10.
  • a union 18 one branch 20 of which leads through the low pressure reservoir into the high pressure reservoir while the other branches are connected respectively to a ipe 21 through which compressed air is supp ied from the compressor or the like and to a pipe-22 leading to the high pressure side of a pressure reducing valve 23.
  • IThe reliet1 side of the pressure reducing valve 23 is connected through a pipe 24 to the high pressure side of a second relief valve 25 which also'communicates through a pipe 26 with the low pressure reservoir 10.
  • valve 23 willy open if and when the dilerence in pressure between the high and low pressure reservoirs reaches or exceeds a redetermined limit so as to permit some of t e air in the high pressure reservoir to escape into the low pressure reservoir while, 1f the .pressure in the low pressure reservoir exceeds a predetermined limit, the relief valve 25.will open and permit escape of the surplus fluid to the atmos here.
  • the low pressure reservoir is automatically supplied with air through the valve 23 and is maintained at the correct pressure relatively to the pressure in the high pressure reservoir.
  • High pressure air may be drawn oil' through the pipe 21 while low pressure air can be drawn olf through a pipe or outlet 27 connected to the pi e 24.
  • the pipe 20 is preferably nt substantially as shown in the drawings so as to a1- low a certain degree of flexibility between the high and low pressure reservoirs and allow a clear passage between the two man holes 16 and 17.
  • a relief valve 28 controlled by a spring 30 is adapted to be opened by air pressurel admitted from the high pressure reservoir y15 behind a piston 31 disposed in a'cylinder 32.
  • the valve when opened permits air topass from a pipe or housing 33 communicating with the high preure reservoir to-a pipe 34 communicat- 1ng with the low preure reservoir.
  • the delivery of high pressure air behind the piston 31 is controlled by a relay valve 35 which is controlled jointly by springs '36, 37 and a diaphragm 38 joined to valve l35, and arranged in ahousing 40 open 'to the atmosphere through port 41, the diaphragm being thus subjected to the pressure in the low pressure reservoir.
  • the arrangement is such that, when the air in the low pressure reservoir drops below a certain predetermined pressure the relay valve 35 opens and 'admits hi gh pressure air to a. pipe 42 communicating with the backof the piston 31.
  • the piston 41 is' thus moved to open the main valve 28 so as to admit air from the high to the low pressure reservoir.
  • the piston 31 is provided with a small leak 43 so that when the relay valve 35 closes due to the pressure in the low pressure reservoir again reaching the predetermined value, the high pressure air will pass through the piston 31 and permit this piston to move so as to close the mam valve 28.
  • a re lief valve 44 the sides of which are subjected respectively to the high andlow pressures may be'provided adapted to open so as to admit high ressure air behind the plston 31 through t e pi 42 and thus open the valve 28 if the dilefience in pressure inthe two reservoirs exceeds a predetermined value.
  • the two reservoirs' may have a common end (not shown) made of such strength as s to withstand the higher pressure, the high pressure reservoir being only partly within the low pressure reservoir in this construction.
  • more than one high pressure reservoir may be disposed within the low pressure reservoir or the air or other fluid may be stored at more than two pressures the reservoirs being arranged one inside the other with the centre one containing the fluid at the highest pressure and the outside one containing the fluid at the lowest pressure.
  • the invention may be'applied to apparatus in which only high pressure or only low ⁇ prcs- ,sure air or other fluid is required or Where fluid of both pressures is employed. Where only low pressure fluid is required this invention enables the space necessary to accommodate storage reservoirs to be reduced, since the high pressure reservoir is disposed within the low pressure reservoir. Further, it permits high pressure lluiclto be drawn olf direct if required.
