Definitions

  • the invention relates to an apparatus for modulating fluid flow according to the preamble of claim 1. More particularly, the invention relates to an apparatus for modulating fluid flow between a first fluid path and a second flow path which branches from the first flow path.
  • US 4,816,155 discloses an apparatus for mixing a solid/liquid slurry and separating said liquid from said slurry, wherein said apparatus comprises a horizontal slurry pipe for carrying a flow of the slurry, a plurality of mixing elements each comprising a cylindrical tube, inserted completely through said slurry pipe at angles perpendicular to the slurry flow, wherein the mixing elements obstruct only a portion of the slurry flow, wherein drainage surfaces of each of the mixing elements comprise openings in the tubes allowing passage of the liquid, and preventing passage of said solid into the mixing elements. Furthermore, this apparatus comprises an exit port connected to a lower end of each of the mixing elements for enabling removal of the liquid from the mixing elements.
  • US 5,474,102 discloses a fluid distribution manifold, where the input piping is inserted in through the manifold's circular intake opening and onto its cylindrical input port.
  • the manifold's intake opening leads through a cylindrical path to a closed terminal end.
  • Along the inner manifold wall there are arranged in a sequence, a number of distribution outlet openings and their respective ports.
  • the invention provides apparatus for modulating fluid flow comprises a first flow path, a second flow path transverse to the first flow path, the second flow path having a fluid inlet which opens onto the first flow path whereby a portion of fluid flowing along the first flow path is diverted into the second flow path, the position of the fluid inlet being set in relation to the direction of fluid flow according to the extent of fluid to be diverted from the first flow path into the second flow path.
  • the position of the fluid inlet is adjustable to vary the extent of fluid diverted as desired. Such adjustment may be made prior to and/or during operation of the apparatus.
  • the fluid inlet comprise one or more apertures.
  • the fluid inlet comprises two apertures circumferentially spaced about the conduit.
  • the first flow path is defined by a conduit having an internal size greater than the external size of the conduit defining the second flow path.
  • the invention has been devised particularly, although not solely, for use in a fluid distribution manifold having a plurality of branch outlets, the arrangement allowing fluid discharging from the manifold through the branch outlets to be regulated.
  • the regulation allows a uniform fluid flow through each of the branch outlets.
  • a conventional manifold having a plurality of branch outlets does not provide an even distribution of fluid flowing through the various branch outlets.
  • a particular application of the apparatus according to the invention is In a horizontal swimming pool falter.
  • a horizontal swimming pool filter typically has an inlet manifold positioned above a filtering media, the purpose of the manifold being to distribute water to be filtered evenly within a water space above the filtering media, so as to allow a laminar flow which does not disturb the surface of the filtering media bed. Uneven distribution of water would cause currents in the water space above the filtering media bed, causing scouring in the surface of the filtering media which in turn causes the filtering media to migrate, leaving areas of reduced media depth.
  • the embodiments shown in the drawings are each directed to a manifold for use in a horizontal swimming pool filter, the manifold being provided to distribute pool water evenly into a water space above a bed of filtering media contained within the filter.
  • the manifold 10 comprises a first conduit 11 defining a first flow passage 13.
  • the conduit 11 is cylindrical and closed at one end by way of a cap 15. Pool water to be filtered is delivered to the flow passage 13 through the other end of the conduit 11.
  • the manifold 10 further includes a plurality of branch lines 19.
  • the branch lines 19 are in pairs on opposed sides of the first conduit 11, each pair of branch lines 19 being defined by a second conduit 21 extending transversely through the first conduit 11.
  • Each second conduit 21 is received within holes 23 formed in the cylindrical side wall of the first conduit 11.
  • Each second conduit 21 has an external diameter which is less than the interior diameter of the first conduit 11.
  • the second conduits do not block flow along the first flow passage 13.
  • the second conduits 21 do, however, act as baffles in the first flow passage 13.
  • Each conduit 21 has a fluid inlet 31 opening into the interior of the first flow passage. With this arrangement, some of the fluid within the first flow passage can be diverted into the second conduit through the fluid inlet 31. The diverted fluid then flows along the two branch lines 19 defined by the respective second conduit 21.
  • each second conduit 21 The extent to which fluid is diverted from the first conduit 11 into each second conduit 21 can be regulated by the orientation of the inlet 31 with respect to the first conduit.
  • the fluid inlets 31 in the five second conduits shown in the drawings can be so positioned that the volumetric flow rate of fluid through each of the branch lines 19 is approximately equal.
  • the fluid inlets 31 in the second conduits 21 have a range of positions including a position which directly faces the fluid flow in the first conduit, a position which faces a direction generally normal to the fluid flow and a position which faces a direction opposite to the fluid flow.
  • the various second conduits 21 are rotated within the first conduit 11 so that the respective inlets 31 assume the required position and then the second conduits 21 are sealingly fixed in position within the first conduit 11.
  • the fixing can be achieved in any suitable fashion such as by adhesive bonding or welding.
  • each fluid inlet 31 in each second conduit 21 is defined by a single aperture in the cylindrical side wall of the conduit.
  • each fluid inlet 31 comprises a plurality of apertures 35 in the cylindrical side wall of the respective second conduit 21.
  • the apertures 35 are in pairs 37, with the two apertures 39 in each pair being circumferentially spaced with respect to each other. The circumferential spacing is such that the centres of the apertures 39 in each pair 37 are approximately at 90° with respect to each other.
  • the second conduit is shown in an orientation in which one aperture 39 of each pair is directly facing the direction of fluid flow and the other aperture 39 of each pair is facing a direction generally normal to the direction of fluid flow.
  • the second conduit 21 is shown in an orientation in which the apertures 39 in each pair 37 obliquely face the direction of fluid flow.
  • the apparatus can be operated in a reverse flow mode in which fluid enters the manifold 10 through the branch lines 19 and exits through the first conduit 11.
  • the fluid inlets 31 can produce a venturi effect in the manifold.
  • the present invention provides a simple yet highly effectively apparatus for modulating fluid flow.
  • the apparatus according to the invention has application for fluid flows other than pool water. Indeed, the apparatus may have application for modulating flow of any liquid or gaseous fluid (or combination thereof).
