Definitions

  • the present invention relates to a metal tank having a closable inspection port, in particular a manhole.
  • cargo tanks such as foodstuffs such as water, milk, wine, glucose, chocolate, fruit juice or chemicals such as acids, solvents, bases, petroleum products such as gas oil, fuel oil or bitumen, or waste. These tanks are mounted on a tank truck or semi-trailer vehicle.
  • the manhole is usually located at the top of the tank and a lid comes close to the manhole, via butterfly type nuts or levers.
  • the manhole is generally provided with a pipe on which is fixed a base ensuring the connection with the lid.
  • the invention aims to obtain a device for closing a manhole tank, and a tank provided with such a device, which overcome the drawbacks inherent in the state of the art and make it possible to secure the closure the cover of the manhole.
  • the PCT patent WO2004074585 describes a manhole or manhole, comprising a first section in which is placed a smaller diameter tubing.
  • the object of the invention is to provide a solution for reducing the size of the closing means of the male holes, and in particular to reduce the height of the parts ensuring the connection with the lid.
  • the invention relates, in its most general sense, to a metal tank having an inspection port which can be closed by a closure plate fastened to a base, characterized in that said base consists of an annular flange directly welded on the edge. the opening of the tank.
  • the edge of the opening is deformed to present a flared collar.
  • the flange has a plurality of non-through holes, each of said holes having a helical insert.
  • the thickness of the flange is between 20 and 30 millimeters.
  • the length of the inserts is between 0.6 and 0.7 times the thickness of the flange.
  • the invention also relates to a method of manufacturing a metal tank having a visit orifice characterized in that the edge of the opening of the tank is deformed to form a frustoconical border of the "collar" type, and in that that an annular flange is introduced into said deformed opening, said flange being welded to the edge of the opening.
  • the metal tank has a shell (1) whose edge of the opening is deformed to form a frustoconical collar (2) whose flanks define a tubular connection zone (3) in which is housed an annular flange (4).
  • the annular flange (4) has an outer section corresponding to the inner section of the tubular connection zone (4). It is fixed by welding, the weld bead (5) being formed along the assembly line between the edge of the collar (3) and the outer edge of the flange (4).
  • the flange (4) shown in FIGS. 2 to 4 consists of a metal part, for example made of steel, having an outside diameter of 560 millimeters and an inside diameter of 530 millimeters.
  • the flange (4) has 24 non-emerging holes (6) regularly spaced to receive M8x1.25 screws for fixing the cover not shown.
  • An insert (7) having a helical internal thread is housed in each hole.
  • the insert has a length of 17 millimeters, for a flange having a thickness of 25 millimeters.
