Definitions

  • the present invention relates to an annular closure with a neck intended for mounting on the open central ends, ending in a spherical manner, of cylindrical pressure tanks.
  • These pressure tanks made of synthetic material normally consist of a relatively thin internal tank for which thermoplastic synthetic materials (acrylonitrile-butadienestyrene copolymer, polypropene, polythene) as well as thermosetting materials (for example reinforced polyester resins) can be used. by glass fibers, vinyl resins reinforced by glass fibers, epoxy resins reinforced by glass fibers).
  • This internal tank also known as a "jacket" provides water resistance and chemical resistance of the tank, but offers no mechanical resistance. To obtain the latter, the shirt is surrounded by a continuously extending wire, impregnated or not with resin. This winding can be done in different ways, namely polar, héiico ') daie or radial.
  • inlets and outlets must be constructed, with the same physical and chemical resistance and the same watertightness as the tank itself.
  • These inlets and outlets are normally found on the lower and / or upper side of the tank and are called annular neck closures.
  • neck closures can be connected supply and evacuation pipes, internal distribution systems, electrical resistances, regeneration valves, etc.
  • a first type is bonded to the internal tank
  • a second type consists of two parts, an O-ring being mounted in each part, rings which are screwed one on the other.
  • the major drawback of the glued type is that the glue, under the pressure of the liquid in the reservoir, breaks down over time, so that the liquid leaves between the neck closure and the reservoir, with the result that the latter n is more waterproof.
  • part of the neck closure is not surrounded by the continuously extending wire.
  • the axis of the covered part is located at another angle.
  • the object of the present invention is to eliminate these imperfections and to offer a neck closure which provides good permanent water tightness and has good mechanical resistance.
  • the neck closure according to the invention consists, on the one hand, of an annular internal part, the end of which located inside the pressure tank, has a larger diameter than that of the end. open central, spherically terminating, of said pressure tank, while on this end are provided lugs which fit into recesses made for this purpose in said opening of the pressure tank, and a large fraction of the face external of the other end is provided with a thread and, on the other hand, by an annular external part whose internal face is provided with a screw, so that this external part can be screwed onto the end with a thread of the internal part.
  • the best neck closure known up to now consists of two parts 1 and 2. In each of these is mounted a sealing ring 3. It is clear that at the height of the point 4, an accumulation of liquid may occur. This liquid can then pass through the wall of the internal tank 5, so that the tank is no longer waterproof. In addition, this can result in the internal tank taking off. In addition, you cannot circle the collar closure all the way up, resulting in the tensions already mentioned.
  • the neck closure according to the invention consists of an annular internal part 6 and an annular external part 7.
  • the end 8 of the internal part 6 located in the pressure tank has a diameter which is greater than that of the spherical, open central end of this reservoir.
  • On this end 8 are provided lugs 9, which fit into recesses 10 made for this purpose in the opening of the pressure tank.
  • These lugs 9 and recesses 10 prevent that during and after mounting, a relative rotational movement of the pressure tank and the internal ring is still possible around the common axis of revolution of this internal ring and the cylindrical pressure tank .
  • a large fraction of the internal face 11 of the internal part 6 is provided with a screw pitch 12.
  • the internal face 13 of the external part 7 is also provided with a screw pitch 14, so that the two parts 6 and 7 can be screwed on top of each other.
  • the annular internal part 6 has here received a shape which is obtained by rotating a rectangle 15 to which a triangular piece 16 is fixed, around the axis 17.
  • the angle of inclination of the side 18 of the triangular part 16 with respect to the axis 17, is equal to the angle of inclination of the end 19 of the internal face of the pressure tank.
  • a screw pitch 21 on the internal face 20 of the internal part 6 is provided a screw pitch 21, so that the appropriate accessory can be screwed into it.
  • a semi-circular notch 12 in which an O-ring 23 is placed is still practical on the entire periphery of the side 18, a semi-circular notch 12 in which an O-ring 23 is placed.
  • the annular external part has a shape which is obtained by rotating the triangular assembly 24 around the axis 17.
  • the angle of inclination of the side 25 of the assembly 24 and the angle of inclination of the face internal 19 of the internal tank 5, with respect to the axis of symmetry 17 of this pressure tank, are equal.
  • the inclination of the side 26 of the triangular assembly 24 is chosen so that this side is perpendicular to the axis of the continuous encirclement of the reservoir.
