Definitions

  • the invention relates to a device for rinsing lines for dispensing liquids, in particular water pipelines with a built-in concealed mixer tap with two supply lines, at least one mixing line and optionally a thermostat.
  • Pipes especially water pipes, must be flushed out after installing contaminants, e.g. B. cutting chips, hemp residues, solder or the like, which have formed during the line laying work. Such flushing does not pose any problems where the pipelines have a free outlet to which valves or the like can then optionally be connected.
  • Such flushing of, for example, stub lines from an already installed thermostatic battery to the shower fitting was not possible without risk of damage to the thermostat insert.
  • the lines to the thermostatic battery or mixer fitting itself could not be rinsed safely. In the case of concealed single lever mixers, flushing could not be done without a risk either Damage to the ceramic cartridge can occur.
  • the object underlying the invention is seen in creating a device of the type mentioned, whether for a thermostatic mixer tap or for a single lever mixer, which are each arranged under plaster, which makes it possible without the risk of damaging the Thermostats or the ceramic cartridge to properly rinse the supply lines of the respective fitting or their mixing line, also to the shower.
  • This object is achieved according to the invention for flushing a concealed mixer fitting with a thermostat by means of a flush fitting which can be screwed into the seat when the strainer and check valve insert or the like is unscrewed from one of the supply lines and has a first flushing position in the manner of a two-way valve, in which the Liquid can be drained from the supply line through the flush valve, while the mixing line is closed, and has a second flushing position in which, when the flush valve is closed, the mixing line is open and the liquid can be drained from the supply line through the mixing line.
  • the flush valve has a screw plug which can be screwed into the seat of the unscrewed sieve insert and which has a central bore in which a cylindrical valve body coaxially corresponding in diameter to the diameter of the seat of the sieve insert coaxially, in each case from the limited to two rinsing positions, is displaceable in such a way that the valve body in the first rinsing position, in which it has been displaced furthest into the seat, closes the mixing line, but the outflow from the supply line through a pipe section extending the valve body, at the end of which a drain valve is arranged, in that it has a coaxial blind bore leading into the pipe section, to which the liquid from the supply line has access through transverse bores.
  • the valve body In the first rinsing position, the valve body thus closes the mixing line and only allows the supply line to be rinsed out through the flush valve, while in the second rinsing position, when the valve is closed, the valve body has been pulled back so far that the water flowing in through the supply line, the now can no longer carry any pollutants, has unimpeded access to the mixing line, including a shower line if necessary.
  • the thermostat in the mixing line can no longer be damaged.
  • Another solution to the task of the invention is characterized by a flushing head which can be screwed on instead of the unscrewed ceramic cartridge, with an intermediate, elastic sealing membrane which, under the influence of the liquid pressure in the supply lines, runs from the valve body into a delimited cavity of the flushing head can be lifted off, and by means of two arranged in the flushing head, pressing the sealing membrane against the two outflow openings in the valve body, from the outside of the flushing head in the closing direction and in the opening direction, mutually actuatable adjusting elements, expediently in the form of set screws.
  • a mixer tap 1 with a thermostat 2 is shown as it is used for installation under plaster and for connection to cold and hot water pipes.
  • the hot or cold water from pipes, not shown, to be flushed enters the supply lines or connecting pieces 3 and 4, which are located through blind holes 5 and 6 for the use of dirt screens, each with a screwed-in check valve, which in present case have been removed, and lines 7 and 8 continue to the thermostat 2, via which they have connection to a mixing line 9 for the outlet of tempered water or for the supply thereof to a shower line, not shown.
  • a flush valve 10 is now provided, which can be screwed into the seat or the thread 12 of the same when the insert is unscrewed from the blind hole 5 and can have two flush positions in the manner of a two-way valve.
  • the sieve inserts are unscrewed from both threads 12 and 13 of the blind holes 5 and 6, respectively, and two identical flushing fittings 10 and 11 have been used to explain the two flushing positions in more detail.
  • the left flush valve 10 has a first flush position in which the water can be drained from the supply line 3 through the flush valve 10 while the mixing line 9 is closed, whereas the second flush valve 11 explains the second flush position, in which the flush valve 11 closes the Mixing line 9 is open. It should be emphasized that, of course, a single flush valve 10 or 11 is sufficient to flush the two supply lines 3 and 4 in succession.
  • the flushing fittings 10, 11 each have a screw plug 14, which can be screwed into the seats or threads 12, 13 of the unscrewed sieve inserts and has a central bore 15 in which a cylindrical diameter of the diameter of the seat or Blind holes 5 and 6 of the sieve inserts essentially corresponding valve body 16 can be displaced coaxially, each limited by the two rinsing positions.
  • valve body 16 In the first flushing position, which is shown by the flushing valve 10, the valve body 16 is in a position in which it has been displaced the furthest into the blind hole 5 and thereby closes the mixing line 9, but the outflow from the supply line 3 through the valve body 16 extending pipe section 17 allows in that it has a coaxial, in the pipe section 17 leading blind hole 18 to which the water from the supply line 3 through two mutually perpendicular cross holes 19 access.
  • the water which may or may be carrying foreign matter, enters the supply line 3 in the direction of arrow B from the water pipeline not to be flushed and enters the coaxial blind bore 18 of the valve body 16 through the transverse bores 19 and the pipe section 17 which extends the valve body 16 flow through the flush valve 10 and exit in the direction of arrow B through a ball valve 20 which is in the open position, optionally into a hose or the like (not shown).
  • an O-ring seal 22 is provided on the valve body 16. It goes without saying that the valve body 16 is only pushed as far in the direction of arrow E into the screw plug 14 that on the one hand the aforementioned sealing and on the other hand the passage of the water from the supply line 3 into the blind hole 18 through the transverse holes 19 is ensured.
  • the now clean rinsing water could be released to the mixing line 9 via the line 7, namely by moving the valve body 16 into the second rinsing position.
  • this second rinsing position is shown using the rinsing fitting 11 arranged on the right in FIG. To simplify parts of this second flush valve 11 have been given the same reference numerals.
  • the ball valve 20 or drain valve is closed in this case, since it is assumed that a rinsing process in the first rinsing position, which was explained above with reference to the rinsing fitting 10, has also taken place for the water pipeline (not shown) which conveys the arrow to the supply line 4 Has.
  • the valve body 16 is in the retracted position shown, in which the rinsing water is cleared the way via the supply line 7, the seat of the unscrewed sieve insert (not shown) or the blind hole 6 and the line 8 to the mixing line 9. In this way, the mixing line or connected shower line can also be rinsed without damaging the thermostat 2, since only clean water has access to it after the upstream lines have already been rinsed and thus cleaned.
  • the respective flush valve 10 or 11 can be removed by unscrewing the screw plug 14 by means of an attachment 23 provided on it, in the form of a hexagon nut or the like, from its seat on the mixer tap 1, which seals with an annular seal 24, whereupon the sieve inserts, not shown, again can be screwed in, which ensure that foreign objects, which may be brought in from the city supply network or the like, do not gain access to the thermostat 2 and the mixing line 9 during the operation of the mixing valve 1.
  • FIGS. 2 and 3 show further details of the two flushing fittings 10 and 11 of the same type, which illustrate how in the embodiment shown the valve body 16 is displaced relative to the screw plug 14.
  • the flush valve 10 according to FIG. 2 is in the same working position in which it is located in FIG. 1. Accordingly, the flush valve 10 with the valve body 16 with its radial seal in the form of the O-ring 22 between the closed end 25 of the valve body 16 and the transverse bores 19 occupies a position which corresponds to the first flushing position in the fitting 1 on the valve, as it continues was explained above.
  • a grub screw 26 which breaks through this, is provided in the wall of the screw plug 14, here in the wall of the hexagon nut 23, as shown.
  • axial groove 27 protrudes on the cylindrical outer surface 28 of the valve body 16.
  • the groove 27 has at its ends right-angled locking grooves 29 and 30, in which the end 31 of the grub screw 26 with a corresponding rotation of the Valve body 16 can be locked after reaching the respective rinsing position.
  • this is the first flush position.
  • the flush valve 10 or the valve body 16 In order to achieve the second rinsing position shown in FIG. 3 using the flush valve 11, the flush valve 10 or the valve body 16 must be rotated and sealed by means of the pipe piece 17 fastened and sealed with screws 32 on the valve body 16 with the help of the sealing ring 32 until the end 31 the grub screw 26 is again at the top of the grooves 27. Then it is only necessary to pull the pipe section 17 in the direction of arrow F (FIG. 3) until the other, in this case lower end of the groove 27 comes to rest on the end 31 of the grub screw 26. Subsequently, the end 31 is locked again in the locking groove 30 by rotation in the same direction, as is shown in FIG. 3 using the flush valve 11.
  • the ends of the locking grooves can also have axially extending extensions 33 in the manner shown, in which repeated locking takes place over a short distance in order to prevent the end 31 of the grub screw 26 from being involuntarily unscrewed from the respective locking groove 29, 30.
  • an O-ring seal 59 arranged in an annular groove 60 of the screw plug 14 ensures a good seal between the valve body 16 and the screw plug 14.
  • FIG. 4 shows a bottom view of the flush fitting in the direction of arrow A in FIG. 2.
  • FIGS. 5 and 6 show a further embodiment of the invention, which also for flushing water pipelines (not shown) with a built-in concealed mixer tap 40 in the single lever construction with ceramic cartridge, as shown in the drawings, with two supply lines 41 and 42 and at least one mixing line 43 suitable is.
  • the ceramic cartridge with the single lever determining the valve position has already been unscrewed from the mixer fitting 40.
  • a screw-on flushing head 44 is now provided, which can be screwed onto the fitting 40 by means of the two fastening screws 45 and 46 in the place of the ceramic cartridge with a single lever mechanism.
  • the flushing head 44 is a cylindrical part, expediently made of plastic, and fits fittingly within the projecting edge 47 of the fitting 40 on an intermediate, elastic sealing membrane 48 which, under the influence of the liquid pressure in the supply lines 41, 42 from the fitting body into an adjacent cavity 50 of the flushing head 44 can be lifted off, namely due to its elasticity or elasticity. Furthermore, two set screws 53 and 54 are arranged in the flushing head 44 and press the sealing membrane 48 against the two outflow openings 51 and 52 in the valve body 49.
  • These two set screws 53 and 54 can be actuated alternately from outside the flushing head 44, for example in the manner shown by means of conventional slotted screw heads 55 and 56, in the closing direction (see set screw 53) and in the opening direction (see set screw 54), in the manner shown Outflow opening 51 closed, the outflow opening 52, however, is opened.
  • the water pressure in the supply line 42 thus raises the sealing membrane 48 through the outflow opening 52, limited to the immediate vicinity of the outflow opening 52, in such a way that a curved flow space connecting the outflow opening 52 and the mixing line 43 is formed in the manner shown that the rinsing water with any foreign bodies is given access to the mixing line 43.
  • the adjusting screw 54 can be screwed back in the direction of the outflow opening 52 into the rinsing head 44, so that the Sealing membrane 48 presses against this outflow opening 52 and closes it. Then the adjusting screw 53 can be unscrewed, whereupon the supply line 41 and the associated water pipeline, not shown, can be rinsed in the same way.
  • the ends 57 and 58 of the adjusting screws 53 and 54 are formed as pressure pieces which are enlarged in diameter and are rounded off in the manner shown to the sealing membrane 48 in the manner of a ball. These thrust pieces are rotatably seated on the adjusting screws 53 and 54, so that no chafing on the sealing membrane 48 and therefore no damage to the same can occur for this reason.
  • both set screws 53 and 54 are tightened in such a way that the two outflow lines 51 and 52 are tightly sealed, then a so-called pressing of the fitting body 40 can also take place in the prescribed manner, whether in the manufacturer's factory or on the part of the installer after the installation of the same for the purpose Leak test of the installed lines.
  • mixer tap according to the invention can be used in the manner described not only after new installation measures, but also advantageously in the case of renovation measures for existing water supply systems which are concerned with removing rust and rust sludge, lime particles and other types of contaminants that can be removed may have formed and deposited over long periods of time.
