Definitions

  • the present invention relates to means for mounting an apparatus through which a fluid passes in a protective envelope.
  • the invention is in particular applicable to a water meter placed in a buried manhole.
  • the water meters located outside a building are housed in envelopes ensuring their protection, in particular against frost.
  • envelopes are partially, in the case of a terminal, or totally, in the case of a manhole, buried in the ground, so as to reach the layers of the ground remaining permanently at positive temperatures.
  • the interior volume of the envelopes is thus maintained at a positive temperature, by convection.
  • the meter To install a water meter, it is known to connect the ends of the buried pipe carrying the water to two vertical tubular rods intended to support the water meter, then to connect the ends of the conduit passing through the meter to the upper ends. of these two rods.
  • the meter includes two tapped lower tubes, with an internal diameter greater than the external diameter of the rods, and two shoulders arranged in the bottom of these tubes. Each rod receives a threaded sleeve, the internal diameter of which corresponds, apart from the clearance, to the external diameter of the rod. Each rod also receives, engaged on its upper end, a sealing ring of compressible material.
  • the rod is then introduced into the corresponding tubing of the water meter until it comes, as well as the sealing ring which it comprises, pressing against the shoulder located in the bottom of this tubing.
  • the threaded sleeve is then screwed into the tubing and tightens the sealing ring between it and this shoulder. The deformation of the ring during this tightening allows the waterproof connection of the meter to the rod.
  • the protective envelope is then engaged on this assembly, then the hole arranged in the ground to receive this envelope is filled.
  • the present invention aims to remedy these drawbacks.
  • the mounting means according to the invention comprise means allowing the fixing of the plate to the envelope, and the device is mounted substantially in the central part of the plate.
  • the plate thus keeps the device at a distance from the walls of the envelope, so that it remains perfectly legible from the upper opening of the envelope.
  • the plate and / or the device or base comprise bearing surfaces inclined relative to the axis of the sealing rings, so as to exert on these rings, during the mounting of the device on the plate, a clamping force, a component of which is directed radially towards the inside of each ring.
  • the rings thus tighten radially the ends of the pipe or rods, so that a perfect seal is obtained.
  • the envelope is constituted by a plurality of elements assembled to each other, in particular by interlocking, one of which comprises an internal structure for mounting said plate.
  • This mounting of the plate in the envelope is thus carried out in a simple and rapid manner.
  • Figure 1 shows a manhole 1 intended to be buried in the ground, ensuring the protection of a water meter (not shown), in particular against frost.
  • the element 9 comprises two connectors 15 bent at 90 °, mounted, by means of screwed nuts, through two openings arranged opposite one another in the element 9.
  • Each of these fittings 15 is connected, on the one hand, to the buried pipe (not shown) transporting the water, and on the other hand, to a vertical tubular cane 16.
  • the upper end of each cane 16 is engaged through a plate 17 and is sealingly connected to one end of a conduit 18 arranged through a base 20, this base 20 being intended to support the meter.
  • the plate 17 has substantially a T shape and is mounted, as is more particularly visible in Figures 2 and 3, on an internal structure 25 that comprises the element 7.
  • This plate 17 comprises, at this indeed, holes 27 at the ends of its branches, and the structure 25 comprises corresponding tapped holes, in which are engaged screws (not shown).
  • the plate 17 also includes two bores 30 of diameter corresponding, apart from play, to the outside diameter of rings 31 ensuring the tightness of the connection of the rods 16 to the base 20, and two annular projections 32 arranged in the lower part of these bores 30.
  • Each of these projections 32 defines an opening of dimension corresponding, apart from play, to the outside diameter of the rods 16, and has an upper face inclined in the direction of the lower face of the plate 17.
  • the base 20 comprises, for its part, on the duct 18, a seat 35 used for mounting the water meter and a stop valve 36 provided with an operating square 37.
  • the base 20 further comprises two lower tubes 45 delimiting two bores 46 of diameter corresponding, apart from play, to the outside diameter of the rods 16, and having an outside diameter corresponding, apart from play, to the inside diameter of bores 30.
  • the plate 17, the bores 30, the annular projections 32, the rings 31, the lugs 38, the pipes 45 and the screws 41 are shaped so that, when the screws 41 are tightened, the lower end walls 47 of the pipes 45 come to bear against the rings 31, and clamp them between them and the annular projections 32.
  • the base 20 can be removed from the plate 17, from the upper opening of the manhole 1, by loosening and removing the screws 41. It is thus possible to access the sealing rings 31, in order to remedy a possible leakage occurring between the base 20 and the rods 16.
  • the element 7 and the plate 17 make it possible to keep the counter away from the walls of the manhole 1, so that this counter remains perfectly readable from the upper opening of manhole 1.
  • the elements 5 to 10 allow, for their part, to constitute a look in a simple and rapid manner.
