Definitions

  • the invention relates to a drain fitting of a cistern according to the features specified in the preamble of claim 1.
  • a drain fitting known with a liftable valve pipe in the vertical direction, at the lower end of a sealing element is arranged.
  • a flow deflector is arranged on the valve tube, whose lower edge, regardless of the position of the valve tube, surrounds the sealing element to form a defined narrow annular gap.
  • a drain fitting known which contains a liftable valve pipe in the vertical direction, which is designed as an overflow pipe.
  • a sealing element of a drain valve is arranged, wherein lifting the valve tube, the sealing element is lifted from a stationary valve seat to allow the rinse water contained in the cistern to flow through the drain valve.
  • the drain fitting is designed as a dual-volume drain fitting and contains two arranged in each brake containers float and two tie rods to trigger either a large flush or a small flush by lifting the overflow pipe, during the small amount of flushing a float is locked.
  • loud closing or gurgling noises can disadvantageously occur, and furthermore a reduction of the flushing performance can occur.
  • a cistern with a drain fitting which has an annular body on the underside of the single brake container.
  • the annular body surrounds in the raised position of the valve or overflow pipe, the sealing element, wherein a dynamic pressure of the outflowing water is shielded such that act on the valve body hardly fluid mechanical forces.
  • the valve should therefore remain open until the brake container is almost empty.
  • the sealing element does not enter the annular space enclosed by said ring but is located below the lower edge of said ring.
  • the invention has the object, the drain fitting of the type mentioned in such a way that the flushing noise can be reduced. Particularly in the case of small-quantity rinsing, in which only a part of the rinse water contained in the cistern flows out through the drain valve, a too loud closing noise is to be suppressed. Furthermore, the drain fitting should allow easy handling during assembly and possibly service measures.
  • the drain fitting according to the invention is characterized by a simple and functional design and includes a flow deflector attached to the overflow pipe such that especially at the end of the small amount flushing an undesirably strong acceleration of the sealing element down to the valve seat and an associated loud closing noise is avoided.
  • the fixedly and preferably liquid-tightly connected to the valve tube flow deflector prevents the flow of water from above presses on the sealing element and this inaccurately accelerated, especially at the end of the small flush.
  • the flow deflector engages over the outer edge of the sealing element, wherein between the outer edge and the Strömungsabweiser advantageously a narrow annular gap is present.
  • the flow deflector is preferably formed as a hollow body, which is closed at the top and down to the sealing element is open, wherein the outer wall is adapted to the inner surface of the housing or the brake reservoir of the drain fitting and in particular is cylindrical.
  • the housing or the brake container contains at the lower end of an annular body, which is open at the bottom and in which the flow deflector protrudes at least partially.
  • annular body which is open at the bottom and in which the flow deflector protrudes at least partially.
  • the annular body forms a cavity, which is suitably closed at the top from the bottom of the housing or brake container and in which protrudes from the bottom of the flow deflector.
  • the height of the cavity is set such that in the closed position of the drain valve, the flow deflector with its upper end something protrudes into the cavity and on the other hand, in the open position of the drain valve of the flow deflector at least approximately completely fills said cavity.
  • the invention includes drain fittings of any design, for example, with only a float, a bell jar or other brake and control devices to close the drain valve in a predeterminable manner after triggering a flushing operation , Regardless of the specific embodiment of the drain valve or the overflow or valve tube, it is crucial to the flow deflector associated with the sealing element, which is arranged above the sealing element and substantially avoids a flow or pressure force from above on the sealing element. Further, the flow deflector is associated with a downwardly projecting edge or annular body of the housing to at least approximately avoid the action of a water flow or of downwardly directed force components on the flow deflector when closing the drain valve.
  • Fig. 1 shows an axial longitudinal section of the drain fitting with a first float 2 for the small flush.
  • first float 2 which is preferably arranged within a first brake container 3, a first pull rod 4, in particular integrally connected to trigger a small amount flush.

  • the housing 5 of the drain fitting further includes a second brake reservoir 16 for a second float 18.
  • the housing 5 and the brake reservoir 16 are connected in a known manner with the outlet valve and for this purpose include radial pin 20, which constitute components of a bayonet connection with the drain valve.
  • the upwardly open second brake reservoir 16 includes a bottom 22 and a surrounding the valve tube 6 at a predetermined distance inner wall 24 such that the valve tube 6 is movable in the direction of the main vertical longitudinal axis 26.
  • the second brake reservoir 16, in which the second float 18 is likewise movable in the vertical direction, contains at least one lateral and / or radially outwardly directed opening or control bore 28, through which the water present in the brake reservoir 16 flows out after the triggering of a large-volume purging.
  • the opening or control bore 28 is shown here for reasons of clarity offset by 90 ° with respect to the longitudinal axis 26 and is located real according to the drawing behind the plane.
  • control spool 30 which is adjustable by means of a control rod 32 in the direction of the longitudinal axis 26.
  • the spool and the control bore are matched to one another that according to the position of the spool 30, the free flow cross-section is adjustable so as to be able to specify the outflow and outflow of the water in the brake reservoir 16 and ultimately the flushing water.
  • the arrangement of the opening or control bore 28 in the lateral outer wall of the second brake reservoir 16 is in view of an annular space below the bottom 22 to be explained below of particular importance.
