Definitions

  • the present invention relates to a filling valve for filling a cistern according to claim 1 and an arrangement according to claim 14.
  • Filling valves are used to fill cisterns of sanitary items such as toilets or urinals.
  • the present invention is based on the object of specifying a filling valve whose membrane can be exchanged very easily in the event of maintenance, even when space is limited.
  • a filling valve for filling a cistern comprises a housing, a water-guiding channel arranged in the housing and having an inlet and an outlet and an inflow valve arranged in the water guide channel.
  • the inflow valve comprises a valve seat with a sealing surface on the valve seat side and a valve membrane with a sealing surface on the valve membrane side. Seen in the installation position, the sealing surfaces lie horizontally. The sealing surface on the valve membrane side can be moved in the vertical direction from a closed position away from the sealing surface on the valve seat side into a release position.
  • the water duct In the closed position, the water duct is closed and in the release position, the water duct is open and the cistern can be filled.
  • the water-guiding channel Viewed in the direction of flow after the valve membrane, the water-guiding channel continues with a horizontal section running horizontally. Furthermore, the water supply channel is deflected in the direction of flow after the horizontal section with a vertical section downwards.
  • the outlet forms the end of the vertical section and is also directed downwards, such that the flushing water flows vertically downwards from the outlet.
  • the horizontal section and the vertical section are part of a cover which can be connected to the housing. When the cover is removed, the valve membrane is accessible.
  • valve membrane can be very easily replaced during maintenance work.
  • inserting a new valve membrane into the filling valve is very simple because the membrane can be inserted into the housing from above. Tedious insertion from the side is no longer necessary.
  • the filling valve is preferably a filling valve which is supplied with flushing water from below.
  • the fill valve is attached to an opening in a bottom wall of a cistern.
  • the filling valve is attached to a side wall of a cistern.
  • the two sealing surfaces are at a distance from one another, so that flushing water can flow between the two sealing surfaces.
  • the plumb direction By expression in the vertical is meant the plumb direction; the horizontal is perpendicular to the vertical or perpendicular to the perpendicular direction.
  • the direction of the plumb, the horizontal, the vertical and the expression “down” refer to the situation in the installed position, ie to the filling valve in the installed state.
  • valve membrane is annular with a bearing portion Bearing surface mounted on the housing and the cover presses the valve diaphragm against the bearing surface in the position connected to the housing.
  • the valve membrane is preferably connected to a guide mandrel which protrudes into a guide section of the water guide channel, the guide mandrel and the guide section being oriented vertically.
  • the guide section is part of the cover and the horizontal section follows the guide section.
  • valve membrane The movement of the valve membrane can be guided by the guide mandrel and the guide section. Furthermore, the valve membrane is given a certain rigidity in its center.
  • the valve seat is preferably arranged with its sealing surface on the valve seat side on the cover.
  • the membrane is particularly preferably moved downwards from the closed position into the open position.
  • the cover is preferably connected to the housing via a swivel lock, in particular via a positive swivel lock or a bayonet lock.
  • the swivel lock can be swiveled relative to the housing and then removed from the housing.
  • the pivoting axis of the pivoting closure preferably runs in the vertical when viewed in the installed position.
  • the swiveling angle required for separating the cover from the housing is preferably a maximum of 90°, in particular a maximum of 60°.
  • a sealing element is preferably arranged between the cover and the housing.
  • the sealing element is, for example, an O-ring or another sealing element.
  • the cover is preferably designed in two parts with a first cover part and a second cover part, the two cover parts each providing a section of the water duct and the two cover parts being connectable to one another via a latching connection.
  • the two-part design has manufacturing advantages in connection with injection molding processes. This is precisely with regard to the deflections of the water guide channel in the cover, in particular when the guide section, the horizontal section and the vertical section are present.
  • the first cover part has said guide section and a part of the horizontal section and the second cover part has the other part of the horizontal section and the vertical section.
  • the outlet of the water-guiding channel preferably has at least one outlet opening which is arranged in such a way that the flushing water can leave the water-guiding channel in a free jet.
  • a plurality of outlet openings are preferably arranged.
  • One outlet opening is particularly preferably arranged centrally in the outlet and a multiplicity of outlet openings are distributed around the centrally arranged outlet opening.
  • the centrally arranged outlet opening preferably has a larger diameter than the other outlet openings.
  • the housing preferably has an opening, with the outlet opening being oriented in the direction of said opening such that escaping flushing water can flow into the housing, the housing having at least one outflow opening through which the flushing water can flow out of the housing.
  • the opening is preferably followed by a guide element, which diverts the flushing water entering the housing to the inside of a side wall of the housing. A further noise reduction can be achieved in this way.
  • the valve membrane can preferably be controlled via a control element, in particular a float.
  • the float can control the control valve mentioned below.
  • the valve membrane is preferably arranged in a valve chamber.
  • the valve membrane divides the valve chamber into a first chamber area and a second chamber area.
  • the first chamber area is part of the water duct.
  • the valve membrane has a through-opening which allows the second chamber area to be filled with flushing water from the first chamber area.
  • the second chamber area has a control valve with a valve body and a control bore, which control valve can be controlled by at least one control element. When the control valve is open, the valve membrane can be moved from the closed position into a release position in the direction of the second chamber area due to the water pressure in the first chamber area.
  • the control bore is preferably arranged in such a way that the water flows out of the second chamber region into the cistern via the guide element.
  • the filling valve preferably has an external thread in the area of the inlet, with which the filling valve can be connected to a water pipe and/or to the cistern.
  • An arrangement comprises a filling valve as described above and a cistern with a bottom wall and with side walls extending substantially at right angles from the bottom wall, the sealing surfaces running parallel to the bottom wall.
  • the bottom wall is also horizontal and the side walls are vertical.
  • the side walls have an access opening through which a plumber can gain access to the filling valve, in particular to the cover of the filling valve.
  • the inflow valve and the outlet are above the waterline at the maximum fill level in the cistern. This means that the above-mentioned free jet of flushing water emerges from the outlet above the water line.
