Definitions

  • the invention relates to a drain valve for a sanitary cistern, in particular toilet cistern, with a valve seat, a valve body having a sealing surface or seal, which is movably guided in the valve seat, and a drain opening limiting valve seat, wherein the sealing surface or seal in the closed state the drain valve rests on the valve seat and releases the drain opening in the opened state of the drain valve, and wherein the valve seat is connected to the valve seat via at least one vertical spacer defining at least one inflow surface upstream of the valve seat in the purge flow direction.
  • the strength of the purge flow in a toilet or urinal is dependent on the height difference between the cistern and sanitary ware, the flow resistance of the cistern connected to the sanitary ware cistern and the flow resistance of the sanitary ware. If the flushing flow is too strong, this can lead to water splashes from the sanitary ware on the toilet seat and on the floor next to the sanitary ware.
  • the flushing flow may be throttled.
  • conventionally different throttle rings are inserted with different diameters in the valve seat of the drain valve to reduce the flow area in the valve seat.
  • the adjustment of the purge flow with the various throttle rings is complicated and uncomfortable.
  • individual of the throttle rings can be lost, which can then rule out a satisfactory adjustment of the purge flow.
  • the invention has for its object to provide a device by means of which the purge flow from a sanitary cistern can be set more comfortable and reliable.
  • the drainage valve according to the invention is characterized in that on the at least one spacer and / or the valve seat at least one purge flow throttle element is adjustably mounted, wherein by rotating and / or moving the at least one purge flow throttle element relative to the spacer, the effective size of Spülstromfy therapies the inlet valve upstream of the valve seat is variable.
  • the invention makes it possible to carry out an adjustment of the flushing flow by means of preferably only a single adjustable element. Since therefore no longer different throttle rings with different inner diameters must be inserted into the valve seat, the setting of the purge flow with the drain valve according to the invention designed considerably more comfortable than with the conventional throttle rings. In addition, the invention offers a cost advantage, since it requires only one additional part (flushing flow throttle element) for different settings of the purge flow.
  • the invention is based on the idea that a flow cross-section reduction to reduce the purge current does not have to take place in the outlet of the valve seat, but can also be arranged elsewhere in the region of the valve seat.
  • the at least one purge flow throttle element of the drain valve according to the invention is sleeve-shaped or hollow cylindrical.
  • the at least one throttle element can be combined very well with the housing shape or valve guide form of proven drainage valves.

  • An embodiment consists, for example, in that the effective size of the inflow surface can be changed by means of the at least one flushing flow throttle element in steps, in particular latching steps.
  • the effective size of the inflow can be very comfortably set depending on a particular sanitary ware model and / or a certain height difference between the cistern and sanitary ware.
  • a table can be made available to the installer, in which various sanitary ceramic models and / or different values with respect to the height difference between the cistern and sanitary ware are specified, the specific sanitary ware models and / or height differences being assigned specific setting or detent stages of the flushing flow throttle element , The installer can then take the table for the respective sanitary ware model or the respective height difference suitable adjustment or detent stage and accordingly adjust the effective size of the inflow by means of at least one purge flow throttle element.
  • an advantageous embodiment of the invention provides that the spacer and / or the valve socket has at least one first latching element, wherein the at least one flushing flow throttle element has at least one second latching element cooperating with the at least one first latching element.
  • An alternative embodiment of the invention is characterized in that by rotation or displacement of the at least one purge flow throttle element, the effective size of the inflow is continuously variable.
  • This embodiment offers the advantage that the strength of the purge flow can be changed very finely and thus optimally adjusted.
  • the at least one spacer and / or the valve socket preferably have a thread, for example an external thread, in which case the at least one flushing flow throttle element has a counter-threading or internal thread meshing with the thread.
  • the at least one purge flow throttle element on its outer side at least one outwardly projecting projection.
  • the projection can be used as a gripping surface and facilitates the handling of the Spülstrom-throttle element.
  • a further advantageous embodiment of the invention provides that the at least one purge flow throttle element has on its outer side at least one symbol which indicates a movement and / or direction of movement of the purge flow throttle element for a reduction or enlargement of the inflow surface. Such a symbol further enhances the ease of operation of the at least one purge flow throttle element.
  • the valve socket above the at least one spacer has a sleeve-shaped or hollow cylindrical portion which is surrounded by the at least one purge flow throttle element and a valve seat facing lower edge, wherein the purge flow throttle element in a position in which the effective size of the inflow is maximum, does not protrude from the lower edge.
