Definitions

  • This invention relates to plumbing apparatus. More particularly although not exclusively it discloses a flow regulator device for toilet flush valves.
  • a flow regulator device for a mains pressure valve such as a toilet flush valve or the like, said device comprising a housing having an outer ring member and an inner cone member disposed centrally of said ring member, one or more fluid flow channels defined between the outer periphery of said cone member and an inner wall of said ring member and a elastic flow restriction member adjacent the inner wall of said ring member whereby in use a pressure differential on said elastic restriction member caused by fluid flow through said channels deforms said restriction member inwardly to at least partially obstruct said channels, the volume of flow through said regulator being thereby kept substantially constant through a range of flow pressures and said outer ring member being disposed within an annular bush adapted for sealing location within the inlet conduit to said mains pressure valve.
  • said cone member is formed with radial fins around the periphery thereof so that at least part of said flow channels are defined between said fins.
  • said elastic restriction member comprise a commercially available O-ring.
  • Figure 1 is a perspective view from the inlet side of a flow regulator according to this concept.
  • Figure 2 is a perspective view of the regulator of figure 1 from the outlet side.
  • Figure 3 shows an example of a toilet flush valve in partial section to which the flow regulator of figure 1 may be fitted.
  • Figure 4 is a cross-sectioal view along the lines A-A of figure 1 with the elastic restriction member undeformed at zero flow pressure
  • Figure 5 is a cross-sectional view similar to figure 4 but with the elastic restriction member deformed inwardly under pressure flow conditions.
  • a regulator designated generally as 1 with a central cone 2 and a surrounding ring housing 3.
  • the cone 2 has radial fins 4 and is held at its position within the ring 3 by flanges 5 as best shown in figure 2.
  • An elastic restriction member 6 which in this case is a commercially available O-ring sits inside a niche in the ring housing 3.
  • Fluid such as water can thus pass through the regulator with the volume flow being related to the cross-sectional area of these channels 7 and the applied pressure.
  • the above assembly sits within an annular bush 8 and is secured in place from the outlet side by a spring clip 9.
  • a peripheral seal 10 which may also be an O-ring sits in a recess around the outside of the bush .
  • the device may be placed within the control cock tail pipe 11 of a conventional mains pressure toilet flush valve 13 as shown by arrow "A" in figure 3.
  • the inlet side of the regulator 1 faces upstream toward the control cock 14.
  • the diameter of the bush 8 is chosen so as to be a close tolerance sliding fit within the pipe 11 so that the peripheral seal 10 engages the wall thereof.
  • one side of the bush also abuts the end 15 of the adjoining valve inlet pipe so as to support the regulator against the force of the incoming water flow.
  • the velocity of flow through the channels 7 causes a corresponding pressure differential between the inner and outer surfaces to act on the O-ring 6.
  • the result of this progressive restriction is that the volume flow rate of water allowed to pass through the flush valve 13 can be maintained at or close to the optimum valve of 1.2 litres per second over a vastly increased range of mains supply pressures including up to 1100 kpa found in high rise buildings. This results in a lower noise level and an extended life for the flush valve.
  • this invention at least in the form of the embodiment described provides a novel and improved flow regulator device for mains pressure flush valves.
  • the example disclosed is only the currently preferred form of this invention and a wide variety of modifications may be made which would be apparent to a person skilled in the art.
  • the shape and configuration of the regulator housing and bush may be changed according to application or design preference.
  • the regulator has been described in relation to toilet flush valves the device may be adapted for other applications such as for example water supply valves in air conditioning plants.

Abstract

L'invention concerne un régulateur de débit conçu pour une soupape, telle qu'une soupape de pression d'alimentation. Ce dispositif comprend un boîtier possédant un anneau extérieur (3) et un cône intérieur (2) pourvu d'arêtes (4) situées au centre dudit anneau (3). Des canaux d'écoulement (7) de liquide sont définis entre la circonférence extérieure du cône (2) et une paroi intérieure dudit anneau (3), ainsi qu'entre lesdites arêtes (4). Un élément élastique (6) de retenue d'écoulement est contigu à l'anneau (3) et, de ce fait, lorsque ledit dispositif est en service, une différence de pression s'exerçant sur ledit élément élastique de retenue (6) et provoquée par l'écoulement du liquide à travers lesdits canaux (7), déforme ledit élément de retenue vers l'intérieur afin d'obstruer au moins partiellement lesdits canaux (7). Ceci permet de maintenir le volume de l'écoulement à travers ledit régulateur sensiblement constant sur une plage de pressions d'écoulement. L'anneau extérieur (3) est situé à l'intérieur d'une bague conçue pour assurer l'étanchéité de l'emplacement à l'intérieur du conduit d'entrée conduisant vers ladite soupape de pression d'alimentation.
