Definitions

  • This invention relates to valves, and in particular to a pressure operated loose ball valve.
  • Ball valves are well known as means of closing an outlet from a chamber and a variety of different forms exist. Many ball valves are of the form described in New Zealand Patent No. 211199 in which the ball valve is activated by turbulent fluid conditions in the chamber in which it is seated. Although this is suitable for the control of a fluid to avoid excess fluid passage causing the turbulence to activate the ball valve,
  • the apparatus described in New Zealand Patent No. 100161 uses a mechanical suction cup to displace the ball from the outlet to the cistern. Such an arrangement may fail due to wear as well as being unable to open the aperture for variable periods of time.
  • the invention consists in a valve comprising a valve housing and a valve member positioned in said housing, said valve member being reversibly positionable in and/or over an aperture, said aperture being provided in or
  • the invention consists in a valve comprising: a valve housing; a fluid inlet in said valve housing; a fluid outlet comprising an aperture in said valve housing; a valve member seatable in or over said aperture to reduce or prevent the flow of a fluid out of said aperture; displacement means to displace said valve member from said seating to allow fluid to flow out said aperture and wherein said displacement means includes a jet of fluid; and control means to control said jet of fluid.
  • This invention may also be said broadly to consist in the parts, elements and features referred to or indicated in the specification of the application, individually or collectively, and any or all combinations of any two or more of said parts, elements or features, and where specific integers are mentioned herein which have known equivalents in the art to which this invention relates, such known equivalents are deemed to be incorporated herein as if individually set forth.
  • Figure 1 is a cross sectional view of a valve according to one preferred form of the invention.
  • Figure 2 is a cross sectional view of a plunger and valve member according to one preferred form of the invention.
  • Figures 3, 4 and 5 are cross sectional views of valves according to alternative preferred forms of the invention.
  • Figure 6 is a section through A-A in Figure 5;
  • Figure 7 is a cross-sectional view through a plunger and valve member according to a further preferred form of the invention
  • Figure 8 is a elevational view of an orifice plate used in the further preferred form of the invention of Figure 7;
  • Figure 9 is an arrangement of part of a toilet cistern showing the arrangement of Figure 7 in use;
  • Figure 10 is a cross-sectional view through a yet further embodiment of the invention.
  • Figure 11 is a cross-sectional view through a yet further embodiment of the invention.
  • the invention relates to a valve having a wide range of applications. Examples of low cost uses for the invention include the incorporation of the valve in a pan toilet system, urinal or irrigation system.
  • the valve comprises a valve housing 30 within which a displaceable valve member 1 is positioned.
  • the valve member 1 can be reversibly positioned in and/or over an aperture or cavity 2 such that when the valve member 2 is positioned in and/or over the aperture 2 it is able to reduce or prevent flow of fluid into or out of the aperture 2.
  • the aperture 2 may be provided in the valve housing 30 or adjacent the housing 30.
  • the valve member 1 is desirably in the form of a solid or hollow ball so that it can be positioned over a standard sized aperture of a conduit 3 for example.
  • the valve includes displacement means for displacing the valve member 1 from the aperture 2.
  • the displacement means includes or consists of a directional, high pressure jet of fluid 4 which is directed at and desirably under the valve member 1.
  • the jet of fluid 4 is directed under the valve member 1.
  • Operating means for activating the jet of fluid 4 can be provided. In the embodiment of Figure 1, this can be in the form of a small solenoid valve 5 which controls the jet of fluid 4.
  • the jet of fluid 4 can be air or liquid but is desirably liquid such as water.
  • the valve member 1 is desirably provided in a confined area within the valve housing 30.
  • the confined area may for example be defined by an upper member 6 as well as a pair of side arms 8 provided on either side of the valve member 1.
  • an internal housing 7 for the valve member 1 may be provided. This is shown in the form of a cylinder but may be any other suitable shape.
  • the upper member 6 and side arms 8 conveniently extend from the internal housing 7.
  • Exhaust apertures 9 are provided in the end of the internal housing 7 so as to enable liquid behind the valve member 1 to escape from the internal housing 7 when the valve member 1 is forced against the biasing spring 10.
  • the spring 10 is provided within the internal housing 7.
  • a selection of inlets 11 and 12 to the valve may be provided. Of course, the inlet 11 or 12 not in use can be covered by a lid or the like.
  • a quick release inspection cap 13 is provided so that the components of the valve can be readily inspected or replaced as required. This may be threaded so that it can be screwed into the valve housing 30. Alternative means for inspecting the internal componentry of the valve are envisaged. For example, a flanged opening can be provided at the top of the valve.
  • O' rings 15 and 16 are provided as part of the inspection cap 13 and adjacent the aperture 2 respectively.
  • the valve member 1 can thus be conveniently positioned substantially in the opening 2 on the O' ring seat 16.
  • FIG. 2 shows an alternative valve member 1 displacement means.
  • a valve 5 such a solenoid valve is provided which controls the jet of fluid 4 through the conduit 18.
  • a plunger member 19 is provided which is desirably biased by a spring 20 and positioned in a plunger housing 21. When activated, the jet of fluid 4 is directed to the proximal end 22 of the plunger 19 and this displaces the plunger 22 towards the valve member 1 which in turn displaces the valve member 1 from the aperture 2.
  • a longitudinal bore 23 through the plunger 19 is provided to allow for escape of the high pressure fluid jet 4 and to assist in displacement of the valve member
  • the internal diameter of the conduit 18 is larger than the internal diameter of the longitudinal bore 23 by say 50%.
  • the valve member 1 is pivotally spring loaded at 24 so that it can return to its original station over the aperture 2 as required.
  • Figure 3 shows yet another valve construction which does not incorporate a spring.
  • the jet of fluid 4 forces the valve member 1 upwards into the confines of the internal housing 7.
  • a pair of side arms 8 and an upper member 6 may be provided to constrict the movement of the valve member 1.
  • Exhaust apertures 9 are provided in the rearwardly facing surface 26 of the internal housing 7.
  • the valve of Figure 3 can be mounted in any position provided that back pressure from the reservoir to the valve is available. In the case of urinal and pan applications, the valve should be provided in an upright position.
  • Figure 4 The embodiment of Figure 4 is similar to that of Figure 2 save that the plunger 19 is provided in a vertical position and the valve member 1 is displaced vertically as opposed to horizontally.
  • Vertical supports 32 for the plunger housing 21 are provided.
  • Figure 5 shows a further embodiment of the invention which shows, in more detail, one form of biasing means for the valve member 1.
  • apertures 27 are provided through the valve member 1, these are sloppy holes to enable a secure fit of the valve member 1 over the aperture 2.
  • a spring loaded bracket 28 is attached to the valve member 1 by the apertures 27 and connected to the valve housing 30 by an external screw fastening member 29.
  • a support baffle 33 may also be provided. The positioning of the spring loaded bracket 28 and valve 1 after displacement is shown by dotted lines.
  • FIG. 7 A most preferred form of the invention is shown in Figures 7 through 9.
  • the valve member 1 is displaced by actuation of plunger 22.
  • the plunger 22 is, in turn, actuated by a jet of fluid 4 originating from orifices 41 and 42 in an orifice plate 43.
  • the fluid comprises water and is directed towards the orifice plate 43 by the flush solenoid 44 shown in Figure 9.
  • the pipe 46 in Figure 9 supplying water to the flush solenoid 44 may be connected to your conventional cold water supply in a house or building.
  • the plunger 22 in the embodiment shown in Figure 7 also has a biasing spring 20 to return the plunger 22 and hence the valve member 1 to its original position upon release of the jet of fluid 4.
  • the orifice plate in this particular embodiment has two orifices 41 and 42.
  • the number and size of the orifices in the orifice plate 43 may vary according to water pressure supplied to the flush solenoid 44.
  • the apparatus of Figure 7 may be incorporated in a toilet cistern or similar apparatus.
  • the cistern 47 may be refilled through inlet pipe 48 in which is positioned a filling solenoid 49.
  • the outlet aperture 2 is substantially sealed by the valve member 1 sitting in the O' ring 16.
  • the flush solenoid 44 opens to apply water pressure to the orifice plate 43 in Figure 7.
  • the jet of water or fluid 4 coining from the orifices 41 and 42 in the orifice plate 43 act on the face 51 of the plunger 22 to displace the valve member 1 away from its seated position over the outlet aperture 2.
  • the flush solenoid 44 Upon closure of the flush solenoid 44, the remaining water pressure behind the rear face 51 of the plunger 22 may be released through the water release opening 52. This will allow slow release of the water behind the activating plunger and a gentle return of the plunger to its original state under the bias of return spring 20.
  • Bracket 53 to support the valve member 1 from the body of the housing so that the valve member 1 may be kept in contact with the activating plunger 22. Due to the hinging of this bracket 53 above the position of the valve member 1, the valve member 1 will return to its seat over the aperture 2 by gravity once the plunger 22 has returned.
  • an inspection hatch 54 may be incorporated in the valve housing to allow inspection, repair or replacement of any of the valve parts.
  • the moving parts are very similar to those used in the previous embodiment.
  • a general change in orientation is involved in the unit with the valve member 1 being displaced downwards against a lower wall 56 of the valve housing.
  • the flush solenoid 44, orifice plate 43 and plunger 22 are all positioned above the valve member 1 to effect the downward displacement.
  • the return of the plunger 22 is again effected by a return spring 20, however, gravity will no longer assist in the return of the valve member 1 into its seat to close the outlet aperture 2.
  • a spring bias acting on the holding bracket 53 could return the valve member 1 to its seat or the fluid flow from the inlet 57 and down the lower wall 56 may act to return the valve member 1 to its seat under this fluid pressure alone.
  • valve member 1 is connected directly to the plunger 22 by the bracketing arm 58.
  • This bracketing arm 58 is hinged at, at least, the connection 59 between the bracket arm 58 and the plunger 52 and is preferably pivotally connected to the valve member 1 as well.
  • the return spring 20 returning the plunger 22 will also act directly on the valve member 1 to return it to its seat over the outlet aperture 2.
  • a valve of this type may be used in the flushing operation from a toilet cistern.
  • the water flow out the outlet 2 may be blocked by the positioning of the valve member 1 in a seat in a O' ring 16 over the outlet aperture 2.
  • the flush solenoid 44 may be activated to supply water pressure through an orifice plate 43 and direct jets of water to a plunger 22.
  • the flush solenoid may be activated for varying lengths of time dependent on whether or not a full flush or a half flush is desired.
  • the plunger in turn presses against the valve member 1 to displace the valve member 1 from its position over the outlet aperture 2. This will now allow fluid flow through the outlet aperture 2 and hence deliver a quantity of water to a toilet pan, urinal or the like.
  • the flush solenoid 44 may close to stop the supply of water to the rear face 51 of the plunger 22.
  • the existing water pressure behind the plunger 22 may then bleed out through a water release 52. This will release pressure behind the plunger 22 and the plunger 22 may return to its original position under the action of a return spring 20. This will then return the valve member 1 to its original seated position over the outlet aperture 2.
  • the jet of fluid 4 may be directed directly at the valve member 1 upon activation of the flush solenoid.
  • the jet of fluid itself will then displace the valve member 1 with no mechanical activation by a plunger or like apparatus.
  • valve member 1 itself may return to its seated position over the outlet aperture 2 through the act of gravitational force, a spring bias or by action of the fluid flow out the aperture 2.
