Definitions

  • the present invention relates generally to valves, and in particular to valves which are immersed in fluids. More particularly, the present invention relates to valves immersed in fluid for controlling the flow of the fluid, preferably liquids such as water, and more preferably the inflow of water to a container. Even more particularly, the present invention relates to inlet valves suitable for use in cisterns for controlling the introduction of water to the cistern.
  • the present invention finds particular application as an inlet valve located in a cistern for controlling the introduction of water replenishing the cistern after flushing in which the valve is provided with positive closing to close off quickly the supply of water from the mains pressure supply, rather than allowing the valve to close gradually as the level of the water in the cistern rises.
  • the noise results from the inlet valve progressively approaching the fully closed position over a period of time, and gradually restricting the flow of water from the mains.
  • the smaller the restriction for admitting water to the cistern resulting from the valve progressively closing the more irritating the noise becomes as the more high-pitched the sound becomes due to its increased frequency.
  • this unwanted noise can continue for lengthy periods of time after the cistern has been flushed, particularly if the seal of the inlet valve is worn or brittle through age. This is particularly annoying in en suite situations at night when the cistern is flushed, which may awaken sleepers in adjoining rooms, particularly in multi-occupancy dwellings, such as apartment blocks, hotels, high density living dwellings and the like.
  • an inlet valve particularly adapted for use in a cistern for controlling the admission of water to the cistern, comprising a movable valve member movable between an open position for allowing flow and a closed position preventing flow, a first actuating member for causing operation of the valve member between the open and closed - 4 -
  • said first actuating member being arranged so that movement in one direction is caused by a first force
  • a second actuating member movable between a contact position and a release position for co-operatively interacting with the first actuating member to effect operation of the movable valve member, being arranged such that when the cistern is replenished to a predetermined level during filling, the second actuating member is caused to move from the contact position to the release position by the first force to facilitate movement of the first actuating member in order to effect operation of the valve member to the closed position.
  • the inlet valve is for use in a toilet cistern. More typically, the inlet valve is located within the cistern for controlling the introduction of water to the cistern, i.e. replenishing the cistern, from mains pressure after flushing of the cistern.
  • the movable valve member is an on/off valve, more typically a plunger-type on/off valve for controlling flow of water from a mains pressure supply pipe, stand pipe or similar.
  • the inlet valve of the present invention when the inlet valve of the present invention is in the open position, the valve allows water to be admitted into the cistern.
  • the valve member when the valve member is in the closed position it prevents flow of water into the cistern. More typically, the valve member is movable from a partially open position to a fully closed position substantially instantaneously.
  • the first actuating member for causing operation of the valve member is a first float or other member capable of movement under the effects of buoyancy. More typically, the float is provided with a stop means for limiting the amount of initial movement, preferably - 5 -
  • the actuating member may be a single first float or a combination of two, three or more first floats.
  • the float is made from a plastics material or similar.
  • the first float is substantially cylindrical or annular in shape. More typically, the first float is provided with an open portion in the form of a cut-out or bore extending axially through the cylindrical float. More typically, the cut-out or bore is provided off-centre or off-axis to the central longitudinal axis of the cylinder. Even more typically, a stand pipe or similar for supplying water under mains pressure is received through the cut-out or bore in use. Typically, the float moves axially along the lengthwise extending direction of the stand pipe in operation.
  • the float moves axially in one direction under the effect of gravity and axially in another direction under the effect of buoyancy. More typically, the effect of buoyancy causes the float to move axially upwards to effect closing of the valve member.
  • the float is provided with an operating linkage extending to the plunger valve.
  • the linkage comprises articulated rods, links, rollers, arms and the like pivotally connected to each other.
  • the second actuating member is connected to or mounted off-centre, or is connected in such a manner which does not correspond to its centre of gravity, so as to be pivotable about its point of connection. More typically, the second actuating member is a second float pivotable under the influence of gravity and is separately pivotable under the effect of buoyancy.

  • the centrally located opening of the second or trigger float is oval shaped, elliptical or eccentric in shape for further facilitating movement of the float.
  • the stand pipe for delivering water under mains pressure is received through the ring or bore of the annular float.
  • the second float by being separately pivotable about the longitudinal axis of the stand pipe or supply pipe, acts as a trigger to cause the first float to provide positive closing of the valve member.
  • the second float is pivotally movable between a contact position in which the second float is in contact with a stop means associated with the first float, thereby preventing movement or further movement of the first float, and a release position in which the second float is pivoted away from the stop means, thereby allowing further movement or continued movement of the first float. More typically, the second float moves from the contact position to the release position under the effect of buoyancy of the second float in the water of the cistern. Even more typically, the second float triggers the continued movement of the first float to complete closing of the valve member, i.e. to provide positive closing of the valve member.
  • the location of the central bore, aperture or opening contributes to operation of the float in use by assisting in pivoting movement. Even more typically, the complete closing of the valve member occurs substantially instantaneously by the movement produced by the first float after being triggered by the second float.
  • the movable valve member is operated to close instantaneously by the first float when triggered by the second float. More typically, the instantaneous closing of the valve member results in more efficient and reliable closing of the valve member to shut off the supply of - 7 -

  • the base or lower surface 4 of the cistern is provided with a suitable aperture through which a stand pipe 6 is received, and sealed thereto with a convention sealing fitting 8, such as for example conventional plumbing fittings used to connect pipes carrying water under mains pressure.
  • a mains pressure delivery pipe 5 located outside the cistern is also connected to the stand pipe inside the cistern to supply water under pressure to the stand pipe.
  • Stand pipe 6 is connected to the normal pressurised water supply and supplies water internally into the cistern. Supply of water to the cistern is controlled by operation of the inlet valve 2.
  • a plunger valve 10 which is one form of the movable valve member is located at or towards the top of stand pipe 6 for controlling the flow of water into the cistern from stand pipe 6.

  • the end of delivery spout 11 is provided with a nozzle or similar for splaying or dispersing incoming water onto the side wall of the cistern, thereby further contributing to silent flow of the water and to silent operation of the inlet valve of the present invention.
  • Valve 2 further comprises a first float 16 which is generally cylindrical in shape and is provided with an internal cut-out or bore 18 located off-axis or off-centre to the central longitudinal axis of the cylinder. Bore 18 extends from the top surface to the bottom surface of float 16. Float 16 is arranged so that stand pipe 6 is received through bore 18 so that float 16 is capable of axial movement both upwards and downwards in the lengthwise extending direction of the stand pipe with respect to the stand pipe in use.
  • a stop means or similar is provided at or towards the top of first float 16.

  • Yoke 20 extends substantially perpendicularly from rod 24 and is arranged to extend substantially horizontally near to the top of float 16.
  • Roller wheel 22 is located at or towards the distal end of horizontal yoke 20.
  • a linkage comprising pivotal link 26 and bell crank 28 extends between the top of rod 24 and valve 10 to transfer motion of float 16 to valve 10.

  • bell crank 28 is provided with a roller wheel 30 for contacting the top of plunger 12 of valve 10.
  • Bell crank 28 is pivotally connected to the top of plunger 12. In use, upward movement of float 16 causes generally downwards and perhaps sidewards movement of plunger 12 to completely close valve 10 whilst downward movement of float 16 causes generally upwards and perhaps sidewards movement of plunger 12 to allow plunger 12 to rise, thereby opening valve 10 allowing flow of water from stand pipe 6 through delivery spout 12 into the cistern.

  • Second float 34 is provided with an upstanding arm 35 extending upwardly from the top surface of the float.

  • Second float 34 is generally of a ring shape or annular shape or oval shape in which the stand pipe 6 is received through the ring or annulus of float 34.
  • float 34 is free to pivot towards roller wheel 22 under the influence of gravity and is free to pivot away from roller wheel 22 under the effect of buoyancy when the water level in the cistern reaches a predetermined level.
  • the eccentric shape of the float assists in this sideways pivotal operation
  • inlet valve 2 In operation of inlet valve 2 generally, as the cistern empties of water after flushing, float 16 falls to its lowermost position with respect to stand pipe 6 under the effect of gravity as the water level in the cistern is lower than the bottom surface of this float and there is no buoyancy effect acting on this float. With float 16 in this lowermost position, float 34 pivots to its at rest - 11 -
  • plunger valve 10 is released to be fully opened with plunger 12 spaced apart from valve seat 14, all as shown in Figure 1. In this position, water is allowed to flow from stand pipe 6 through valve 10 and delivery spout 11 into the cistern.
  • Floats 16 and 34 remain in their respective positions with respect to each other, as shown in Figure 2, until the water level reaches a predetermined level well above the upper surface of float 16 which has the effect of pre- tensioning or pre-loading float 16 and providing it with a latent force or stored potential energy for future operation.
  • float 34 begins to be affected by the force of buoyancy.
  • float 34 pivots away from roller wheel 22 due to the increasing effect of buoyancy on this float. As float 34 pivots it moves slightly away from roller wheel 22 under the continued influence of buoyancy into the release position in which roller wheel 22 is released from contact with the undersurface of float 34.
  • plunger 12 provides positive sealing of valve 10 to substantially instantaneously stop the supply of incoming water to the cistern. This sudden interruption to the supply in a positive movement prevents the prolonged leakage of water under pressure which is responsible for the "hissing effect" experienced in conventional cisterns as the inlet valve closes gradually and progressively over a period of time.
  • the inlet valve 10 remains completely closed by the effect of buoyancy on float 16 at all times until the water is released from the cistern by flushing. As the water is flushed, the level in the cistern lowers until it is below both floats 16 and 34 so that float 34 pivots to its at rest position and float 34 falls to its lowest position both under the effect of gravity. In so doing, plunger 12 is released from valve seat 14 thus opening valve 10, thereby allowing the flow of water to replenish the cistern. This configuration remains until the cistern is replenished with water and the level of the water causes float 16 to rise as described previously.
  • roller wheels are used to eliminate wear and reduce unwanted friction. Accordingly, modifications or substitutions of these wheels may be made by any suitable means.
  • the inlet valve of the present invention is unique in construction in that it is either in the open position or in the fully closed position, there being no delayed progressive movement between the open position and the fully closed position, - 13 -
  • the float moves a linkage which is so designed that it produces, by a compounded mechanical advantage, considerable force on plunger 12 to suitably close valve 10 and has sufficient force to keep it completely closed against very high mains pressure.
  • the continuing effect of buoyancy on float 16 when the cistern is full of water results in plunger 12 being held in the fully closed position with sufficient force to keep it fully closed against the mains pressure, even in conditions of very high mains pressure.
  • float 16 and the linkage act as a mechanical lock to keep plunger 12 in the fully closed position when the water level is above the predetermined level .
  • Another advantage of the present invention is that the shape of the floats permit the vertical stand pipe to be surrounded by the floats, thus reducing the space required for the components of the valve and for its operation, thereby providing for greater flexibility of design.
  • the inlet valve of the present invention may be used with any flush valve, either single flush or dual flush, together within the same cistern so that both the inlet valve and the flush valve or valves operate in combination with each other.

Abstract

L'invention concerne une valve d'admission (2) permettant de réguler un écoulement de fluide. Cette valve comprend : un élément valve mobile (10), capable de passer d'une position ouverte à une position fermée ; un premier élément d'actionnement (16) conçu pour passer, sous l'effet de la flottabilité, à une position intermédiaire dans laquelle ce premier élément d'actionnement (16) est préchargé ou prétendu de manière à pouvoir se déplacer pour faire fonctionner ledit élément valve mobile (10) ; et un second élément d'actionnement (34), capable de passer par pivotement d'une position de contact destinée à empêcher tout mouvement du premier élément d'actionnement (16), à une position d'enclenchement permettant à ce premier élément d'actionnement (16) de se déplacer pour actionner ledit élément valve mobile. Ainsi, lorsque le fluide atteint un niveau prédéterminé, le second élément d'actionnement (34) provoque un déplacement du premier élément d'actionnement (16) permettant de fermer ladite valve d'admission (2).
