Definitions

  • the invention relates to a device which is used to mount through a wall of an enclosure, at the location of an opening provided for this purpose, at least one dip tube and preferably several dip tubes which are immersed in the fluid. that this enclosure contains.
  • the device of the invention is particularly useful for mounting dip tubes on water heating containers and in particular on electric storage water heaters which contain water under pressure.
  • the dip tubes are made up of shielded electrical resistors which are bent into a hairpin, and by a tube closed at its inner end and intended to contain a sensitive element of a thermostat.
  • One or more shielded electrical resistors bent in pins and a thermostat tube are used for supply by an appropriate electrical network.
  • an appropriate electrical network When one is not in this case, when one uses only a shielded hairpin resistor and a thermostat tube, one is led for reasons of standardization to make the assembly through the same opening which is defined on the balloon by a suitable flange with a passage diameter of the order of 80 to 100 mm. Even if we accept the use of a smaller flange for mounting a single resistor and a single thermostat tube, the space required at the two ends of the bent resistor and at the end of the tube thermostat leads to a flange of still large diameter.
  • tubular heating resistors pass through a wall through an opening in which a rubber pad is mounted.
  • the end parts of the resistors pass through holes in this buffer and the latter is compressed in an axial direction between two plates applied respectively one on its internal main face, the other on its external main face.
  • the pad is compressed between these two plates by means of a bolt which passes through the pad and the two plates; the head of this bolt is pressed against the inner plate and the nut against the outer plate.
  • the merit of the invention is to be freed from the routine belief that a metal plate is necessary or that a rubber stamp must be crushed axially.
  • the dip tubes are mounted in a sealed manner in a passage opening of a conventional flange by means of a device comprising on the one hand a thick pad of elastomer or similar material through which the dip tubes pass.
  • this pad having a body engaging the flange with an outer face and an opposite inner face, pierced with holes for passage of the dip tubes, having an outer flange pressing against the outer face of the flange and on the other hand a rigid rigid counter-flange, preferably made of metal, pierced with holes through which the dip tubes pass freely, this counter-flange applying against the external face of the tampon body and having a diameter sufficient to cover and compress at least an annular part of the external flange against the external face of the flange, the internal face of the body of the tampon being left free from any compression.
  • the necessary thickness of the buffer is obtained on at least one of its faces, thanks to bosses located at the points of passage of the dip tubes.
  • these bosses are located on the face of the pad against which the counter-flange rests.
  • the device described here as an example is intended for a water heater whose temperature is of the order of 60 ° to 80 ° C for example and the pressure of 10 bars maximum; it is intended for mounting three heating tubes bent into a hairpin (only one is shown) and a thermostat tube (not shown), which leads to a diameter of passage through the mounting flange of approximately 90 mm. Given these conditions of use, the device does not appear in the simplest aspect of the invention nor in its most elaborate aspect which could, one or the other, be adopted in d other conditions of employment.
  • the tank 1 of the water heater is provided with a flange 2 with a passage 3 for three armored tubular resistances 4 bent in a pin and therefore each having two outer end parts 5, 6 terminated by lugs 7, 8 for electrical connection.
  • a tube (not shown) intended to contain a temperature-sensitive element also penetrates into the tank 1 via the passage 3.
  • the latter is hermetically closed by a pad 9 of elastomeric composition comprising a body 10 and bosses 11.
  • the latter are located at the locations of the holes 12 provided through the buffer 9 for the passages of the dip tubes (resistors 4 and thermostat tube) which enter the tank 1 and which are immersed in water.
  • the thickness of the pad 9 therefore includes that of the body 10 and that of the bosses 11. In this example, the latter are located on the outer face 13 of the pad 9.
  • the body 10 Around the body 10, there is a flange 14 intended to be applied against the outer flat face of the flange 2 and pierced with holes as in the latter.
  • the body 10 is introduced into the passage 3 of the flange 2; it has a truncated cone profile and the dimensions are chosen so that it occurs in contact between the truncated side face and the flange 2 and so that it results in radial compression of the body 10.
  • a solid counter-flange 16 made of rigid material is tightened by bolts 17 in order to properly compress the flange 14 and give rise to the radial compression defined above as a result of the thrust and the maintenance of the body 10 in the passage 3 of the flange.
  • the result of this mounting is a stiffening of the buffer 9 such that the dip tubes are firmly held spaced from each other inside the tank 1.
  • the counter-flange 16 is applied against the outer face where the bosses 11 are located and it is pierced with holes 18 which allow these to pass.
  • the holes 18 have a diameter which allows the bosses 11 to pass freely. A smaller diameter could be adopted which would produce a radial compression effect on the bosses 11.
  • Figure 2 shows a hole 12 before mounting the dip tubes; its inner face is advantageously provided with several beads 19 spaced apart in longitudinal direction which each extend circularly in a transverse plane. These beads 19 facilitate the sliding of the dip tubes 4 in the holes 12 and provide a better seal in the event of high pressure.
  • the end parts 5, 6 of the heating tubes 4 are each provided with an insulating bead 20, with an ogival profile, which also facilitates passage through the holes 12.
  • Figure 3 is a view on a smaller scale which shows that one can also use a pad 9 devoid of bosses on its outer face; the body 10 is thicker and it is subjected to radial compression by means of a hooping ring 21 which is forced into a suitable groove 22 provided in the frustoconical lateral face of the body 10.
  • the body 10 of the pad 9 is not subjected to any compression in the axial direction, more precisely the inner face of the body 10 opposite its outer face 13 is left free and does not is not subjected to any compressive force.
