Definitions

  • the invention relates to a flush-mounted connection housing for at least one water valve, in particular a water mixing valve and / or water distribution valve, with at least one inflow opening and at least one outflow opening, a connection surface for a water valve being formed on the end face.
  • a flush-mounted connection housing has become known through prior public use.
  • This flush-mounted connection housing has a connection on both sides for the incoming cold or hot water, while a connection for the mixed water outlet is provided above and below.
  • the connection surface is arranged parallel to the building wall surface and designed so that separate channels for the incoming cold and hot water and a channel for the mixed water discharge is provided, so that a known mixing valve cartridge can be tightly attached to the connection surface.
  • the mixed water generated in the mixing valve cartridge can be supplied to either the upper or lower mixed water connection via a water distribution valve arranged in the flush-mounted connection housing.
  • the mounting hole in the flush-mounted connection housing for the water distribution valve can be closed with a stopper, so that mixed water is then applied to both the upper and the lower connection.
  • the connection that is not required in each case can then also be closed with a plug.
  • Approval authorities in various countries are increasingly demanding that sanitary outlet fittings are to be designed to be intrinsically safe, so that dirty water cannot flow back through water outlets. This applies both to hose shower connections and to a bathtub spout that is located below the top edge of the bathtub.
  • Intrinsically safe fittings are those in which safety devices are integrated that prevent backflow.
  • the invention is therefore based on the object in Preamble of claim 1 specified flush-mounted connection housing to improve and train intrinsically safe.
  • This object is achieved in that a hole for the Drain is provided, which is dimensioned so that at least one backflow preventer can be arranged in it.
  • the flush-mounted connection housing 1 shown in Fig. 1 has two laterally opposite connections 12, 13 for the inflowing hot and cold water.
  • a mixed water connection 14 is formed at the upper and lower area.
  • the two mixed water connections 14 are connected to one another via a receiving bore 15 for a water distribution valve 5.
  • a connection surface 10 is formed parallel to the building wall - not shown in the drawing - to which a plate 2 is fastened in a sealed manner with screws 21 and O-rings 22.
  • the flush-mounted connection housing shown in Fig. 1 can be configured in various ways. In the embodiment shown in FIG.
  • a backflow preventer 3 is arranged in the flush-mounted connection housing 1, in which a closure member which is pressed against a valve seat by a spring against the permissible flow direction is provided in a bore 11.
  • the hot and cold water flowing in via channels 24, 25 is converted into mixed water in a mixing valve cartridge 4 and fed to bore 11 via a drain channel 26.
  • the mixing valve cartridge 4 is fastened in a sealed manner to the plate 2 with tensioning screws 41 which can be screwed into threaded bores 23.
  • the approximately 11 horizontally arranged in the flush-mounted connection housing 1 is dimensioned so that it can accommodate one or two check valves 3.
  • the backflow preventer is designed as a structural unit and enclosed by an approximately cylindrical sleeve 31, an O-ring 32 being provided in the outer jacket of the sleeve 31 in a circumferential annular groove for sealing on the wall of the bore 11.
  • a shoulder 113 is formed in the downstream region, against which the backflow preventer 3 bears axially.
  • a spacer sleeve 114 is also arranged between the end face of the plate 32 and the upstream end face of the backflow preventer 3.
  • a drain channel 111 is formed in the wall of the bore 11, which leads into a distribution chamber 112.
  • the receiving bore 15 for a water distribution valve 5 is provided concentrically with the distribution chamber.
  • the water distribution valve 5 is in this case designed as a changeover device which automatically returns to a preferred outflow position and by means of which the outflowing mixed water can optionally be switched over to a shower spout or a bath tub spout.
  • the flush-mounted connection housing works as follows: The cold and hot water flowing in via the connections 12, 13 reaches the mixing valve cartridge 4 encapsulating the individual valve elements of a mixing valve via the channels 24, 25. If the mixing valve is opened by means of an adjusting lever 42 that can be moved in two degrees of freedom, then depending on the mixing valve position Mixed water generated, which is discharged via the drain channel 26 into the bore 11 of the flush-mounted connection housing 1. The mixed water flows here through the backflow preventer 3, the closure member being moved away from the valve seat, into the drain channel 111 and from here into the distribution chamber 112. In the position of the water distribution valve 5 shown in the drawing, the mixed water arrives from here via a connecting channel 115 the lower mixed water connection 14 for a line for a bathtub spout.
  • the water distribution valve 5 is switched over, the connecting duct 115 is shut off, at the same time the water outlet from the distribution chamber 112 into the upper mixed water connection 14 is released for a hose shower. If a negative pressure now occurs in a supply line network during the tap operation, the backflow preventer 3 in the bore 11 prevents dirty water from being sucked in via one or both mixed water connections 14. If the water outlet from the water distribution valve 5 in the upper mixed water connection 14 is released for a hose shower, the water distribution valve 5 automatically switches over at a negative pressure, releases the water outlet in the lower mixed water connection 14 and blocks the upper mixed water outlet 14 and the backflow preventer 3 as two series-connected safety devices with increased security. This effectively prevents contaminated water from entering the supply network in an inadmissible manner. The valve is therefore intrinsically safe.
  • two are in series consecutively arranged backflow preventer 3 in the bore 11 arranged.
  • the spacer sleeve 114 omitted.
  • a water distribution valve 5 is at this embodiment is not provided.
  • the location hole 15 is closed with a stopper 51.
  • the two arranged above and below Mixed water connections 14 can be used optionally.
  • the unused mixed water connection 14 is to be closed with a stopper.
  • the double arrangement the backflow preventer 3 creates increased safety, so that if a backflow preventer fails still an impermissible sucking back with the other can be prevented by dirty water.
  • the flush-mounted junction box 1 with one or two non-return valves connected in series 3 operated.
  • the flush-mounted connector 1 also, e.g. B. in countries where non-return valves are not prescribed without a non-return valve 3 can be used.
