Definitions

  • This invention relates to a valve device for controlling fluid flow through an opening, particularly although not exclusively for a ventilation opening for exhausting moist air from a room or other space within a building.
  • the vent comprises a shutter or louvre arrangement mounted across an outlet leading to a duct.
  • a humidity-sensitive mechanical drive such as a tensioned absorbent fibrous cord or ribbon connected to a linkage is used to adjust fluid flow through the outlet by opening and closing the shutter or louvre arrangement.
  • An object of the present invention is to provide a valve device which can be operated to adjust fluid flow through an opening in an efficient and effective manner with a relatively low operating force.
  • a valve device for controlling fluid flow through an opening, said device comprising a support having therein the said opening, and a closure structure mounted relative to the support so as to be movable across the opening between different positions in which the closure structure differently restricts the opening, characterised in that the closure structure comprises a body containing at least one slot bounded by edges, the body being deformable so as to cause the edges to move relative to each other.
  • the slot may be of any desired configuration. However, in a particularly preferred embodiment a curved slot is used especially a spirally curved slot.
  • Such multiple slots may be wholly separate or they may be joined as desired.
  • multiple slots having different angular and/or directional characteristics may be desirable.
  • inner and outer concentric helixes of opposite hand are used.
  • the (or each) slot is preferably formed as a slit in a sheet or panel which preferably is otherwise solid, i.e. substantially imperforate.
  • This sheet or panel is preferably substantially planar in a first closure said condition and is twisted or buckled or otherwise distorted into a non-planar configuration in the (or each) other open said condition.
  • the slot preferably has its edges parallel to each other.
  • the body may alternatively be non-planar e.g. curved or otherwise shaped.
  • the arrangement may be such that the opening is substantially sealed in one said condition of the closure structure e.g. the aforesaid closure condition, i.e. the (or each) slot is closed up with the edges touching or closely juxtaposed and the body is formed from a solid imperforate material. It is, however, also possible for the (or each) slot to allow fluid flow therethrough in all conditions, such flow being more restricted in one said condition, e.g. the aforesaid closure condition, than in the (or each) other condition.
  • one said condition of the closure structure e.g. the aforesaid closure condition
  • the (or each) slot is closed up with the edges touching or closely juxtaposed and the body is formed from a solid imperforate material. It is, however, also possible for the (or each) slot to allow fluid flow therethrough in all conditions, such flow being more restricted in one said condition, e.g. the aforesaid closure condition, than in the (or each) other condition.
  • the arrangement may be such that the body is biassed to one of said conditions whereby an operating force is required only to change the (or each) slot to the (or each) other said condition.
  • This biassing may be effected resilient properties of the body and/or by use of a spring or other biassing means in conjunction therewith.
  • the body is preferably biassed to an open most condition of the (or each) slot.
  • no biassing may be used whereby an operating force is required for movement to all conditions.
  • this involves twisting or buckling such that the edges bounding the (or each) slot move relative to each other transverse to a plane containing the slot.
  • This may be achieved by application of a drive force to the body at an angle to the longitudinal extent of at least a portion of the (or each) slot whilst the body is retained against bodily movement, the force thereby causing the body to twist or buckle by distortion at the (or each) slot.
  • the body may be retained in position centrally relative to the slot curvature, provision being made for application of the drive force substantially in the plane of the body.
  • a bridge member may be fixed to the support so as to extend over the body with a suspension member such as a rod or bar rigidly by joining central region of the bridge member and the body, guide means being provided to guide movement of the body in a direction transversely to the suspension member in the plane of the body.
  • a suspension member such as a rod or bar rigidly by joining central region of the bridge member and the body, guide means being provided to guide movement of the body in a direction transversely to the suspension member in the plane of the body.
  • this may be derived from a humidity sensitive mechanical drive which comprises a structure, such as a fibrous cord or ribbon which changes dimensions e.g. by contraction or expansion with changes in moisture level.
  • a structure of this kind may be used in conjunction with a biassing means such as a spring and/or mechanical devices such as guides, levers, pulleys, linkages or the like.
  • movement of a spring linked to the body is opposed by a tensioned fibrous cord or ribbon where increased humidity causes the cord or ribbon to extend and permit movement (extension or contraction of the spring) which moves the body.
  • the body may be held captive differently with the drive force being operative to move a central region of the body.
  • the drive force may be applied linearly and/or rotationally in the plane of the body and/or at an angle to such plane, or otherwise.
  • valve device of the invention will find particular application in the context of a ventilation system for a building whereby the said opening is a vent outlet leading to a vent duct through which moist air is exhausted.
  • valve device may be used for any suitable purpose in any suitable context.
  • Figures 1-3 show a valve device for controlling fluid flow through a ventilation duct of a building ventilation system.
  • the ventilation duct which may comprise a flexible pipe runs between an opening e.g. in a ceiling of a room and an outlet of the building.
  • the opening is a circular opening 1 cut in a rigid solid board 2 mounted in the room ceiling.
  • the board 2 may be formed from MDF or other material.
  • the circular opening 1 is covered with a substantially square sheet or panel 3 formed from a readily deformable solid i.e. imperforate plastics material such as ABS.
  • This panel 3 lies on top of the board 2 and is larger than the opening 1 such that a peripheral edge region 4 of the panel 3 overlies the solid part of the board 2 around the opening 1.
  • the panel 3 is held in position by a mounting arrangement comprising two flanges 5 which are fixed to the board 2 at opposite sides 6 of the panel 3 at fixing positions beyond the panel edges.
  • the flanges 5 project from their fixing positions inwardly over the adjacent edge regions 4 of the panel 3 with a slight gap therebetween.
  • the mounting arrangement also comprises a ridged elongate bridging element 7 which extends over the panel 3 being attached at opposite ends to vertically upstanding arms 8 attached to the flanges 5 at ends thereof beyond the panel 3.
  • the bridging element 7 runs parallel to and spaced from the panel surface perpendicularly to the two opposite sides 6 located by the flanges 5.
  • a rigid rod 9 is fixed between the centre of the panel 3 and the centre of the bridging element 7 so as to run perpendicularly to the panel face and the bridging element 7.
  • the panel 3 contains a spiral cut 10 which runs substantially from the centre of the panel 3 to an outer position adjacent to the centre of one side edge of the panel 3.
  • the outermost turn of the spiral 10 is substantially coincident with the circular rim of the opening 1.
  • the valve device further includes a drive device which comprises two arms 11 each of which is slidably located at one end within a short slot in the panel 3 which extends generally parallel to the located sides 6 of the panel 3 and which projects beyond one transverse side 12 of the panel 3 at its opposite end.
  • the two arms 11 are located respectively close to the two sides 6.
  • pivot arm 13 which is pivotally mounted at one end within a block 14 fixed to the board 2 adjacent the transverse side 12 opposite to the arms 11. The opposite end of this pivot arm 13 is pivotally mounted on the panel 3.
  • a spring 15 is fixed in compression between a mid position of the pivot arm 13 and a fixed position on the board 2.
  • a humidity sensitive fibrous cord 16 e.g. formed from Nylon runs alongside the two sides 6 of the panel 3 and between and connected to the arms 11. This cord 16 is anchored at opposite ends respectively to the block 14 and to a fixed point on the board 2.
  • cord 16 contracts and is in tension so as to bear against the arms 11 and hold the arms 11, the panel 3 and the pivot arm 13 against the spring force.
  • the panel 3 is substantially planar and the edges of the slot are in close parallel contact whereby the panel 3 acts to seal the opening 1 such as substantially to prevent flow of air therethrough.
  • the centre of the panel 3 is restrained by the rod 9 whereby such movement of the panel 3 causes the panel 3 to distort by twisting or buckling so that the edges of the spiral slot 10 are moved away from each other, the slot 10 opens up and sections of the panel 3 between the slot turns are deflected both upwardly and downwardly out of the plane of the board 2.
