Definitions

  • the invention relates to a sanitary water valve in the form of a single shut-off valve or a mixing valve with one or more actuation handles, in particular a single-lever mixer valve with water paths in the form of water inlets and at least one water outlet or water outlet, and with a fitting housing for accommodating a metal alloy comprising lead components of the control elements, which are combined in particular in a cartridge, the inlet pipes forming the water inlets being connected to the cartridge via an insert piece arranged adjacent to the cartridge.
  • mixer taps In addition to the usual brass fittings, sanitary mixer taps have already been proposed, the water-carrying parts and functional elements of which are essentially made from materials that are harmless to health.
  • These further developed mixer taps for example single-hole mixer taps, have an insert made of a brass alloy, in which the inflow pipes made of copper for the cold and warm water and optionally an outlet pipe made of copper are inserted in a pressure-tight manner. With this insert, the cartridge made of plastic and ceramic for the quantity and temperature control of the water is optionally with additional functional groups interposed, pressure-tight by anchor bolts.
  • the invention has for its object to completely eliminate the contact points between water and the components consisting of a brass alloy and to create a completely "lead-free" sanitary mixer tap.
  • the basic idea of the invention provides that the waterways are provided on the inside to avoid contact with the water that is passed through them by means of a waterproof shield consisting of a lead-free material that is harmless to health.
  • the shield consists of a coating applied to the inside of the waterways and made of a lead-free material which is harmless to health, the insert for connecting the inlet pipes additionally being made of plastic; in this case so-called open cartridges can also be used, in which the water from the cartridge itself enters the water path provided with a corresponding inner lining; Since all parts with which the water comes into contact are made of lead-free material, the water does not come into contact with fittings containing lead.
  • the shielding is designed as a separate tubular or tubular water channel inserted into the waterways and made of unhealthy, lead-free material, this water channel being opposite the assembly and functional groups consisting of a brass alloy containing lead is completely sealed.
  • the separate water channel as well as the feed pipes are connected to the cartridge via an additional hole in the insert, so that the mixed water from the cartridge enters the separate water channel directly and is led to the outlet head without touching lead-containing fittings.
  • the inserts for connecting the inlet pipes are usually made of lead Brass, and in order to avoid contact of the water with the brass containing lead in this area, an embodiment of the invention provides, between the cartridge and the insert piece made of lead-containing brass, a disk made of a material which is harmless to health, for connecting the inlet pipes and the separate water duct, including the inclusion to arrange of associated sealing elements and to clamp them pressure-tight; this ensures that both the inlet pipes and the separate water channel are passed through the insert piece made of lead-containing brass and only open into the cartridge via the interposed disc, additional sealing elements being arranged between the disc and the insert, which ensure a backflow of the water prevent from the cartridge over the disc to the insert.
  • the interposed disc is made of a corrosion-resistant steel, so that it is able to absorb the forces that occur when the functional modules are braced.
  • the sealing elements arranged in the area of the connections of the insert, in which the supply pipes for the cold and warm water and the separate water channel are inserted, for example by brazing, are preferably inserted into recesses in the insert and lie after the cartridge has been braced with the insert the pipes inserted around the walls of the recesses in a liquid-tight manner.
  • the outlet head is plugged onto the separate water channel by means of a cylindrical sealing element and passed through an opening in the fitting housing, the sealing element having two outer annular shoulders, between which the receiving section of the outlet head is received and secured in position.
  • the outlet head has a cylindrical extension of its receiving section on the inlet side with an inwardly directed locking pin which engages in a corresponding opening in the valve body.
  • the pressure-tight connection between the outlet head and the outlet-side end of the separate water channel is in turn ensured by a cylindrical sealing element which has an outer annular shoulder which lies radially in a receiving bore of the outlet head and is provided with a further inner annular shoulder which has its inner section strikes on the end face of the separate water channel or an inserted intermediate piece and with its outer end face on a shoulder in the receiving bore of the discharge head.
  • the cylindrical sealing element inserted into the outlet opening of the plastic housing of the liquid distributor again has an outer annular shoulder which rests on the end face and / or in a recess in the outlet opening and an inner annular shoulder which limits the depth of insertion of the outlet pipe into the plastic housing.
  • the design proposed according to the invention for sanitary water valves uses on the one hand the advantageous properties of brass alloys for certain functional assemblies, such as their relatively high strength and their good properties for processing and processing, and ensures using relatively simple means, that any contact of the water with these functional modules is excluded. Since all water-bearing or water-contacting components and functional groups are made of materials that are harmless to health or are provided with a suitable lining, a sanitary water valve is created in this way, in which the possibility of absorption of heavy metal alloy components by the water is completely excluded .
  • the single-hole mixer tap 1 has a self-contained fitting housing 2 made of a lead-containing brass alloy, into which an insert 8 which is pressure-tightly connected to the cartridge 5 is inserted and is screwed to the housing 2 by a screw 55.
  • an outlet head 51 made of a material which is harmless to health is attached, and the water path 52 between the outlet head 51 and the insert 8 is lined with a waterproof coating 53 made of a lead-free material which is harmless to health.
  • the coating 53 can be applied, for example, in an immersion process.
  • the supply lines 11 for the cold and warm water are inserted pressure-tight, additional sealing elements 7 being provided in the area of the connection points of these lines.
  • the water is passed through the plastic insert 8 into the cartridge 5 and from here also via the insert 8 into the water path 52, in which it flows to the outlet head 51; since the inside of the spout belonging to the fitting housing 2 is provided with a coating 53 made of a suitable material, the water does not come into contact with lead-containing alloy parts at any point.
  • FIG. 2 shows an exemplary embodiment of the invention in which, in order to avoid contact between the water and alloy parts consisting of lead-containing brass, a separate water channel 10 made of a material which is harmless to health is arranged between the cartridge 5 and the outlet head 9.
  • the inlet pipes 11 for the cold and warm water and the separate water channel 10, which consist, for example, of copper, are first inserted pressure-tight into the insert 8, which in this case consists of a brass alloy, by brazing.
  • an outlet head 9 is attached to the outlet-side end of the separate water channel 10 using a cylindrical sealing element 14 and is passed through an opening 47 in the fitting housing.
  • this part of the valve housing 2 is designed as a cover 49, which, for example, is chrome-plated like the valve housing 2 and is connected to the valve housing 2 by a screw 50.
  • the sealing element 14 has two outer annular shoulders 12, 13, between which the inlet-side receptacle 45 of the outlet head 9 is arranged pressure-tight and secured in position.
  • the sealing element 14 is also provided with an inlet slope 15, which facilitates the plugging of the sealing element 14 together with the outlet head 9 onto the separate water channel 10.
  • the discharge head 9 is also made of a material which is harmless to health, preferably of plastic.
  • FIG. 4 shows a single-hole mixer tap 1, which is provided with a liquid distributor 20, by means of which a switchover of the water outlet between the outlet head designated in this case with 18 belonging to the mixer tap 1 and a separate outlet device, for example in the form of a hand shower to be arranged in addition to the mixer tap 1, which is connected to the cartridge 5 via a further pipeline 19, can be carried out.
  • the liquid distributor 20 is pressure-tight in a plastic housing 17, which is provided with an outlet opening 23, and with the interposition of in this case, two disks 6 made of a corrosion-resistant steel alloy are arranged between the insert piece 8, which in this case also consists of a brass alloy, and the cartridge 5 and braced together with these assemblies by tie rods 48 in a known manner.
  • the inlet pipes 11 as well as the further pipe 19 leading to the separate outlet device for the mixed water are in turn inserted into the insert 8, sealing elements 7 according to the invention being used in the area of the connection points to the disk 6, which are clamped together with the aforementioned assemblies and are liquid-tight Ensure connection between the water-carrying parts and the insert.
  • the separate water channel 10 is inserted with its inlet-side end in a pressure-tight manner by means of a cylindrical sealing element 22, while on the outlet-side end of the separate water channel 10 an outlet head 18 is also attached in a pressure-tight manner with the aid of a cylindrical sealing element 27 and in a form-fitting manner with the fitting housing 2 is connected.
  • the outlet head 18 - as can be seen in detail in FIG. 5 - has an extension 24 on the inlet side, which is provided with a locking pin 25.
  • the locking pin 25 engages in an opening 26 of the fitting housing 2 and thus ensures a positionally secure fixation of the outlet head 18.
  • the cylindrical sealing element 27 for the pressure-tight connection of the outlet head 18 and separate water channel 10 has an outer annular shoulder 28 which is radial in the receiving bore 35 of the Outlet head 18 abuts and is also provided with an inner annular shoulder 29, which rests with its inner portion 21 on the end face of the separate water channel 10 or on an inserted intermediate piece 30 and with its outer end face 34 strikes a shoulder 33 of the receptacle 35 of the discharge head 18.
  • the bevel 32 on the inlet side of the sealing element 27 in turn makes it easier to place the outlet head on the separate water channel 10.
  • the sealing element 22, with which the inlet-side end of the separate water channel 10 is inserted into the outlet opening 23 of the plastic housing 17, has an analogous configuration to the sealing element 27 at the end of the outlet.
  • the outer annular shoulder 28 of the sealing element 22 lies against the end face 37 or in a recess 38 of the outlet opening 23, while the inner annular shoulder 29 limits the depth of insertion of the outlet pipe 10 into the plastic housing 17.
  • the insert 8 is inserted into a base body 44 of the fitting housing 2 together with the liquid distributor 20 arranged in the plastic housing 17 and the cartridge 5 braced with the insert 8; a corresponding representation of this is shown in FIG. 6.
  • the single-hole mixer tap 1 shown in FIG. 7 is equipped with a removable hand shower 39, which is inserted into a receptacle 40 of the fitting housing 2 and is connected to the additional water channel 10 via a flexible connecting line 41.
  • the separate water channel 10 and the inlet pipes 11 are in turn inserted pressure-tight into the insert 8 consisting of a brass alloy, additional sealing elements 7 being provided in the area of the connection points, as described above.
  • a ventilation element 43 with a valve arrangement is provided between the insert 8 and the cartridge 5.
