Definitions

  • the present invention relates to a calibratable valve for water discharge from toilet cisterns of toilet bowls.
  • the present invention relates to a valve provided with adjustable means that allow the control of the amount of water that can be discharged from a toilet cistern during each activation and depending on the specific washing requirements of WC cisterns.
  • the valve of the present invention is particularly suitable to be adopted in all the systems of discharge of a liquid, for instance water, wherein one wishes to control and adjust the discharged flow rate such as, for instance, the toilet cisterns for domestic systems.
  • toilet cisterns are provided with discharge valves whose function is that of allowing the downflow of a given amount of water from said cisterns to the toilet bowls underneath for the necessary washing. It is also known that the discharge valves utilized for this purpose are not provided with a means for the adjustment of the discharge, but are substantially configured in such a way as to cause the downflow of a constant water amount on each of their opening, independently on the different washing and/or rinsing needs, with obvious, useless and onerous water wastes.
  • Toilet cisterns are also known that are provided with discharge valve having leaf springs.
  • Such springs have the purpose of allowing, depending on the required washing type, a quick return of the valves, with an accelerated closing and a limitation of the amount of water discharged.
  • Object of the present invention is to obviate the above drawbacks.
  • valve for the discharge of water from toilet cisterns in the toilet bowls underneath comprising a fixed component wherein a tubular element slides that has an upper annular element, an intermediate float ball and a lower sealing gasket, said valve being provided with means for the adjustment and control of the flow of discharge fluid, acting on the descent and closing speed of said tubular body and the associated gasket.
  • the calibratable valve for water discharge from toilet cisterns of toilet bowls of the present invention comprises a substantially fixed component located in the inside of a toilet bowl, which component is provided with at least a radial opening associated to a corresponding interception element; a tubular body constituted by an upper annular element, an intermediate float ball and a sealing gasket inserted in the depressed bottom end that slides within said fixed cylindrical component; said tubular body being associated to a lifting means whose activation may be either independent or coupled to a second lifting means that operates on an adjustable load equalizing control.
  • the calibratable valve of the present invention allows to control and adjust the amount of water that. on each activation, is discharged from the toilet cistern to the toilet bowl underneath, depending on the specific washing and/or rinsing needs. This is obtained through the greater or smaller interception of the radial opening of said fixed component to which it corresponds: a smaller or greater downflow of water under the float ball, an increase or a decrease of the valve descent and closing speed, and the ensuing greater or smaller water downflow in the toilet bowl.
  • the calibratable valve of the present invention allows to adjust the same amount of water discharged from the cistern to the toilet bowl proportionally to the closing speed to be imparted to said valve.
  • Such closing speed is adjustable not only through the variation of the passage area of said radial opening, but also through the variation of the closing load which can be obtained on the valve by means of the action of a supplementary balance weight.
  • the calibratable valve of the present invention indicated as a whole by 10 in Figure 1, comprises:
  • the mobile central body 1 is inserted in the fixed cylindrical component 4 and the internal walls of said fixed component are a guide for the float ball 3.
  • Bottom 11 of the fixed component 4 is provided with an opening with a raised edge 13 protruding towards the inside and the outside, through which opening the mobile body 1 passes and can slide guided by said protruding raised edge 13.
  • the annular element 2 constitutes a bearing of the central mobile body 1, striking the upper edge 4' of the cylindrical component 4.
  • gasket 5 sealingly engages on the drain of a toilet cistern.
  • the cylindrical component 4 engages with the cistern through any connection means, for instance bayonet means or the like.
  • the friction ring nut 8 comprises at least a closed sector having a height and an extension sufficient to cover and intercept from partially to totally the corresponding opening 7, and at least an open sector having a height and an extension sufficient to allow a partial to total opening of said corresponding opening 7.
  • Ring nut 8 is preferably realized with anti-sliding grip peripheral grooves and/or knurls.
  • the tubular body 1, which constitutes the valve stem, the annular element 2, the float ball 3 and gasket 5 are shifted upwards, with axial sliding in the inside of the fixed cylindrical component 4.
  • the detachment of gasket 5 from the drain causes the direct discharge of water from the cistern to the toilet bowl underneath.
  • the tubular body 1 and the associated float ball 3 start descending by gravity along the water-filled component 4.
  • the descent speed is slowed only by the presence of such water that can leak only through the annular passage gap 12, defined by the difference between the internal diameter of the circular opening with the raised edge 13 and the external diameter of the tubular body 1, and especially through the slit-like radial opening(s) 7.
  • the interception ring nut 8 By adjusting the position of the interception ring nut 8, it is possible to vary the passage section of the radial opening(s) 7, causing the more or less rapid water downflow from the inside of the fixed cylindrical component 4. By suitably rotating the interception ring nut 8, it is possible to obtain a total opening minimum interception configuration, and a total closing maximum interception configuration, passing through intermediate variable interception configurations with respect to the extreme positions. In so doing, it is possible to control the descent speed of the tubular body 1 an therefore of gasket 5, which at the end of its stroke engages in the drain of the toilet cistern, interrupting the flow of water discharged in the toilet bowl.
  • the ring nut 8 By arranging in the desired position the ring nut 8 so as to throttle the passage area of the slit-like radial openings 7, it is possible to cause the discharge from the cistern of a water amount smaller than its maximum rate.
  • the amount of water that may be discharged on each activation can be smaller of the usual nine liters provided in the standard cisterns.
  • the interception element 8 of the friction ring nut type with a slit-like opening rotary movement may be replaced by an interception element, always of the friction ring nut type with a rotary movement provided with one or more through-holes partly and/or totally aligneable with corresponding peripheral through-holes obtained on the fixed component 4.
  • Another solution may include a vertical movement interception element of the gate-like type that superposes to slit-like openings or of other types, etc.
  • the calibratable valve 10 as has been described till now is clearly applicable and utilizable in an independent manner on toilet cisterns, but in an alternative application still more advantageous from the point of view of the containment of water consumption may be also associated to a supplementary activation means, such as for instance a second push-button 20 associated to a balance weight 21.
  • a supplementary activation means such as for instance a second push-button 20 associated to a balance weight 21.
  • the pressure exercised on the push-button 20 causes the rotation of a lever 22 about its fulcrum 23, and the lifting of its end 24.
  • the latter is provided with a hooking seat 25 which, during the rotation, engages a tooth 26 that protrudes laterally from lever 18 connected with the first activator or push-button 17.
  • the tubular body 1 and the associated float ball 3 start the closing descent but in this case said descent does not take place only by the gravity of said elements, as in the previously described solution, but also by effect of the supplementary thrust caused by the balance weight 21 tied to lever 22. Under the action of a greater load, the valve closes quicker, and the amount of water discharged through the drain is still more reduced.
  • the amount of water discharged may be adjusted by shifting the balance weight 21 along its supporting arm 27; for this reason and according to an easily and economically realizable solution, the balance weight 21 engages arm 27 by means of a threaded coupler.
