Definitions

  • the chamber enclosed by the, innermost tube andk by the discs serves as a liquid tank; This chamber is connected with a liquid system through a port equipped in the disc.
  • the enclosed annular chambers between concentric tubes serve as a gas reservoir.
  • This invention relates to a kind of bladder type pressure liquid accumulator suitable for lower hydraulic pressures.
  • the conventional bladder type accumulator consisting of a gas bag of elasticand flexible material installed in a liquid tank of rigid material and connected to a pressure liquid system
  • the bladder or the gas bag dellates or inates according to the pressure changefof liquid, to accumulate or discharge liquid from or to the system and at the same time absorb pressure pulsations and hydraulic shocks.
  • This type is suitable for high pressure, but not for low liquid pressure, such as in water service or in pipe lines in the industries.
  • FIG. 1 is the longitudinal section of an embodiment of this invention, while FIG. 2 is that of another embodiment, FIG. 3 is their cross section, and FIG. 4 shows the state of the invented accumulator working under a certain hydraulic pressure'.
  • the accumulator of this invention comprises a cage-like shell 1 of a rigid material, either of metal or other suitable pressure resisting material, consisting of a pair of circular discs 2 and 3 which are integrally or rigidly connected together by a number of stays or bolts 4.
  • a number of tubes 6, 7, 8 and 9 with different diameters, of elastic and exible material, are concentrically installed between the discs 2 and 3, the ends of each tube being air tightly fixed to the discs 2 and 3.
  • a chamber 11, defined by the innermost tube 6 and the two discs 2 and 3, serves as a pressure liquid tank, which is communicated with a pressure liquid system through a liquid port in the disc 2 or through a liquid inlet port 5 and an outlet port 5' provided in the discs 2 and 3 respectively.
  • Each of the annular chambers 12, 13 and 14 dened by the concentric tubes 6, 7, 8, 9 and the two discs 2 and 3 serves as a pressure gas reservoir, in the same manner as in a conventional bladder type accumulator.
  • These reservoirs, charged with gas under a certain standard .pressure jointly inflate or deate in response to any pressure change in the pressure liquid system, and cooperatively serve as a gas bag like that in a conventional bladder type accumulator.
  • FIG. 4 which shows the accumulator of FIG. 1 under liquid pressure
  • the cylindrical'wall 6 of the liquid reservoir deforms to 6' and the liquidv reservoir 11 expands to 11'.
  • the tubes 7, 8 and 9 expand respectively to 7', 48 and 9', and the chambers 12, 13 and 14 are compressed and deformed respectively to 12',l 13' and 14.
  • Another superior characteristic of the accumulator of this invention is that the area of total surface of the-elastic tubes absorbs any shock which is induced in the pressure liquid system, so that the accumulator absorbs not only large hydraulic shocks but also smaller pressure pulsations, caused in comparatively low pressure liquid, which have so far been difficult to absorb.
  • An accumulator as embodied in FIG. 2, is to be installed, as already described, in a pressure liquid pipe line so that liquids are sent through the accumulator, which absorbs harmful pressure pulsations, which have been an inevitable source of trouble both in the oil industries and in water service.
  • Another merit of the invented accumulator is its low cost and easy operation, due to its simple construction.
  • An accumulator comprising:
  • (A) a rigid cage-like shell comprising (1) a pair of end members and (2) a plurality of circumferentially spaced connecting members holding said end members in generally coaxial spaced apart relationship,
  • An accumulator comprising:
