Definitions

  • the invention relates to a mixer tap for water tapping points, with a valve body that has an outlet, a mixing lever and a cartridge housing and is releasably braced with a washstand or other base part, the connecting lines for cold and warm water as in the cartridge housing from above through the Insertable plug-in tubes are formed in the cartridge housing interior, which are equipped on the housing-side end piece with a fixing part and can be clamped between the housing base and the seat nipple.
  • Such a mixer tap is known from DE-OS 23 28 361.
  • the push-in tubes are also inserted into the housing base from above, whereby they are fixed by means of a screw connection between the housing base and the seat nipple via their fixing parts. Sealing rings are attached to the top of the fixing part, which ensure a corresponding seal against the interior of the cartridge housing.
  • a disadvantage is the multi-part design of the cartridge housing, because the bottom can be connected to the housing itself only by clamping the plug-in tubes. This requires not only a corresponding separate component as the housing base, but also a corresponding screw connection.
  • Another disadvantage is that a precise axial arrangement of the plug-in tubes is required to ensure a tight fit or to cover a corresponding seat. Depending on the base part, such an axial arrangement of the plug-in tubes is not always possible, so that it is necessary to solder further arc-shaped tubes to the plug-in tubes, so that the rationalization effects are eliminated again by clamping the plug-in tubes.
  • a mixing valve is known from DE-OS 32 45 890, in which the plug-in tubes are inserted into the housing bottom from below. However, then is one Fitting required, which then also fixes the plug-in tubes when the housing is put on and braced.
  • the plug-in pipes must also be used axially with this mixer tap, whereby the effort due to the additional molded part is not insignificant, especially since the fitting of the valve onto the fitting with the plug-in pipes looking out above depends on the skill of the fitter.
  • the invention is based on the object of simplifying the connection assembly of mixing fittings, in particular with regard to the connection of the plug-in pipes.
  • the seat nipple has a blind bore provided for receiving the end piece and a sealing ring and in that the end piece of the half-tubes is hemispherical and has an outlet for the water in the center of the hemispherical surface.
  • the push-in tubes can simply be inserted in advance into the corresponding creaming hole in the base, whereupon the seat nipple and the cartridge are then pushed into the interior of the cartridge housing.
  • the sealing ring In the blind hole is the sealing ring, which then automatically rests on the hemispherical end piece of the plug-in tubes and for a complete one Sealing takes care.
  • the fitter does not need to exercise special care because the individual parts are automatically inserted and sealed into each other, whereby the stable housing base, which is an integral part of the cartridge housing, can be used advantageously because it forms a corresponding bearing during assembly.
  • the end piece of the plug-in tubes has the outlet for the water on the top of the hemisphere, so that the continuation of the water is ensured, regardless of whether this outlet surface is free or only partially. This ensures that the connection is fully effective. It is also advantageous that the individual plug-in tubes do not have to be inserted axially to the seat nipple or other component, but also at any angle, whereby a seal is always guaranteed.
  • the pipes can be inserted at an angle or it is possible to use angled fittings from which the plug-in tubes can be seen to look almost vertically, so that the further course of the connecting lines is easily secured.
  • the end piece of the plug-in tubes is spherical.
  • a spherical version can generally be manufactured more easily with the brass or copper pipes used here, the spherical version also ensuring that the sealing ring is always fixed between the surface of the spherically shaped end piece and the deepest hole of the blind hole.
  • the sealing ring is adapted to the blind bore and can be positioned in the borehole. This allows the sealing ring to be inserted into the blind hole beforehand and then the seat nipple to be inserted into the interior of the cartridge housing. It then automatically sits with its blind hole on the end piece of the plug-in tube and seals effectively here.
  • the hemispherical surface is designed to merge into the fixing part designed as a collar. It is advantageous that with the manufacture of the hemisphere or the spherical surface of the end piece also the collar is also trained for which a separate work process is not required. This makes production easier and, at the same time, ensures, as desired, a particularly stable design of the upper end or the end piece of the push-in tubes.
  • An anti-rotation device for the individual plug-in pipes is expediently achieved in that the plug-in pipes are equipped with a securing web which is designed to extend on the outer wall in an extension of the collar.
  • the plug-in tube With the insertion of the plug-in tubes into the receiving bore in the housing base, the plug-in tube is thus fixed and thus it is ensured that the sealing ring with the fitting of the seat nipple is positioned properly so that the desired sealing is always guaranteed.
  • an extension area adapted to the securing web must be provided in the receiving bore, which is achieved according to the invention in that a puncture adapted to the securing web is provided in the receiving bore in the housing base. This puncture is relatively easy to manufacture and ensures the exact fit of the bridge tube on the one hand and the sealing ring on the other.
  • the plug-in pipes used can be easily processed and also meet the necessary requirements with regard to service life if they are designed as dome pipes made of brass. They can then be easily connected to the connecting lines.
  • plug-in tubes have a stop for extension tubes in the predetermined distance from the fixing part, taking into account the respective cartridge housing.
  • extension tubes are pushed onto the lower, elongated plug-in tube and then soldered or otherwise connected, so that such a connection can be made easily and quickly.
  • the connecting lines in the cartridge housing may be expedient to arrange the connecting lines in the cartridge housing at an angle or to form the entire body at an angle, in order to achieve a purely optically favorable shape Armature to reach.
  • This is advantageously achieved if the blind bore formed in the seat nipple and the through bore as well as the receiving bore in the housing base are designed to be correspondingly inclined, so that the web tubes can be inserted, fixed and sealed accordingly.
  • the through bore, blind bore and receiving bore vertically if this proves to be expedient, for example, within a correspondingly slanted fitting body. It is advantageous that the necessary seal can always be reached between the plug-in tube and the seat nipple, which rests almost loosely.
  • the plug-in tubes are ultimately held or fixed in the interior of the cartridge housing in that the cartridge, together with the seat nipple, is clamped against the housing base via a tension screw that can be screwed into the cartridge housing in the interior of the cartridge housing. It has an advantageous effect that a stable housing base is present, which is part of the cartridge housing, so that the force applied by the clamping screw can be relatively low, but still always ensure the necessary fixation of the plug-in tubes on the one hand and their sealing.
  • the exact positioning of the plug-in tubes is carried out also through the securing bar and the puncture formed in the receiving bore.
  • the clamping screw has locking grooves corresponding to locking projections formed on the inside of a cover cap. This allows the clamping screw to be pushed onto the seat nipple and the cartridge by applying slight pressure and can also be fixed at the same time. No further screwing or other work is required, which is particularly the case when the clamping screw is slightly screwed into the cartridge housing. For this purpose, it has a thread that corresponds to the internal thread in the interior of the cartridge housing.
  • the invention is characterized in particular by the fact that a mixing valve is created which ensures a relatively easy handling and thereby also specifies an always secure and tight fit of the plug-in tubes for the inexperienced. So that's one Installation of such mixing fittings is made considerably easier, but at the same time it gives the possibility of inserting the plug-in tubes at an angle which is expedient for the respective application.
  • the plug-in tubes can ultimately be set vertically or at practically any angle, it being of course expedient to design the bores in the housing base accordingly in order to ensure that the respective plug-in tube is seated in the predetermined position.
  • the individual parts are simply pushed into the fitting from above, the plug-in tubes having an inexpensive connection option for further connecting lines, so that overall the connection installation can be expedient and quick.
  • Fig. 1 shows a mixer tap 1, which is a single-lever mixer tap.
  • the valve body 2 has a wide spout 3 and the already mentioned mixing lever 4, here in the form of a one-hand lever.
  • the cartridge housing 5 is a stable body which, as the other figures show, also has an “inner life”. From the bottom of the cartridge housing 5, the connecting lines 6, 7 protrude, through which warm and cold water are introduced into the valve body 2.
  • the pool outlet 8 can also be seen, which flows from above via the adjusting device 9, i.e. can be operated from the mixer tap 1.
  • Fig. 2 shows the valve body 2 in section, wherein the cartridge housing interior 10 can be seen.
  • the cartridge 11 and the seat nipple 12 are arranged, which are clamped against the housing base 15 by means of a clamping screw 13 with a cover cap 14.
  • the clamping screw 13 has a thread 16 so that it can be screwed onto the cartridge 11 and the seat nipple 12 to exert pressure into the interior 10 of the cartridge housing.
  • only a relatively low pressure is required in order to ensure that the cartridge 11 and the seat nipple 12 fit once and on the other hand to secure the connecting lines 6, 7 and the plug-in tubes 18.
  • the plug-in tubes 18 with their specially designed end piece 19 having a fixing part 20 are unstable and with the cartridge housing 5 a housing bottom 15 forming a unit from above, i.e. has been introduced from the cartridge housing interior 10.
  • the fixing part 20 is not used here to support a sealing ring 21, but rather, as explained further on, as a stop, corresponding to the receiving bore 32 formed in the housing base 15.
  • the seat nipple 12 also has an area into which the end piece 19 of the plug-in tube 18 extends.
  • Fig. 2 and Fig. 3 illustrate that the through hole 23 in the seat nipple 12 on the side facing the housing bottom 15 via a Blind hole 22 has. This blind bore receives the sealing ring 21 shown in FIG. 2 in the deepest hole 27 and ensures that an effective seal is created here.
  • the particular shape of the end piece 19 of the plug-in tube 18 is shown in particular in FIG. 4, it being clear that this end piece 19 has the shape of a hemisphere.
  • the sealing ring 21 lies on top of the hemisphere 25, while the hemisphere then merges into the fixing part 20.
  • the outlet 26 for the water is approximately in the middle of the top of the hemispherical surface 25, which is also illustrated in FIG. 2 in particular.
  • the so-called fixing part 20 is designed here as a collar 28, which virtually represents an end region of the hemispherical surface 25. Attached to this collar 28 is a securing web 29, which is also illustrated in FIG. 5, which leads a certain distance vertically downward on the outer wall 30. This securing web corresponds to the puncture 23, which is carried out in the receiving bore 32 in the housing base 15. The same is illustrated in FIG. 6.
  • plug-in tubes 18 have a stop 34 which facilitates the attachment of further connecting lines and also their connection. These other connecting lines are pushed up to the stop 34 and then connected accordingly.
  • the web tubes 18 can have virtually any position or inclination, an always secure fit and a seal being ensured.
  • the exact seating position of the plug-in tube 18 is achieved by the securing web 29 and the puncture 33, the sealing ring 21 being inserted and inserted in a completely sealing manner in the deepest hole 27.
