Definitions

  • FIG. 1 illustrates a closed vase with a membrane currently sold.
  • This vase comprises two half-shells (1) and (2) made of cold-rolled sheet metal with a peripheral edge (1.1 - 2.1) for connection, a starting sleeve (3), a valve (4) and a valve cover ( 5), a deformable elastomer membrane (6) separating the water and air chambers and a crimping ring (7).
  • the connection of the two half-shells together is effected by a chain stitch welding operation carried out using the knurl on the peripheral edges (1.1 - 1.2), thus ensuring the tightness of the assembly.
  • the aim sought after according to the request was to study a new design of the mode of connection of the two half-shells together which offers advantages in the reduction of manufacturing and assembly costs while presenting the reliability and tightness of the 'apparatus.
  • the solution provided responds satisfactorily with a particular adaptation of the two half-shells of the tank. It is also applicable to expansion compensators, or pressure fluid reservoirs and other tanks of the same type.
  • the reservoir of the type comprising two half-shells assembled together with a membrane for separating the fluid chambers and a rod is remarkable in that the two half-shells extend beyond their side wall by a flared profile.
  • a first offset pan outwards and a second consecutive side facing outwards forming a flange, the docking being established on said flanges while the consecutive flaps form a support zone or seat of the fluid separation membrane, said membrane being arranged at its end to ensure the insertion and maintenance of the rod whose profile is similar and complementary to the V-profile defined by the two consecutive sides; said flanges being assembled together by an appropriate means.
  • said flanges are stapled to each other by successive reversals and lastly against the external wall of the tank.
  • the two half-shells (10-11) of the tank include a bottom wall (10 1 -11 1 ) and a peripheral side wall (10 2 - 11 2 ) of variable height.
  • the two half-shells (10-11) constituting the reservoir extend beyond their aforementioned side wall by a flared profile with a wall (10 3 -11 3 ) offset towards the outside, then by a second consecutive pan (10 4 -11 4 ) forming a turned collar "also outwards and in a plane perpendicular to that of the wall (10 2 -11 2 ) of the half-shells of the vase
  • the flanges (10 4 -11 4 ) are in contact with one another ensuring perfect stability of the two half-shells with respect to each other. of the junction of the half-shells by crushing the membrane located between the rod and the flared sides of those half-shells.
  • the anal ⁇ concave is defined by the two sides (10 3 - 11 3 ) sufficiently open to ensure engagement and centering of the end (12 1 ) of the fluid separation membrane in the reservoir or expansion tank in the particular case.
  • This elastomer membrane for example, is arranged in said peripheral end with protruding beads (12 2 -12 3 ) or equivalent members allowing the insertion and maintenance of a metal rod (13) whose profile is similar and complementary or even strictly parallel to that defined by the two consecutive sections (1 0 2 -11 2 ) .
  • the rod adapted to the shape of the tanks has a perimeter substantially smaller than that of the internal perimeter of the tank or expansion tank in the particular case. the rod compresses the aforementioned membrane into the seat shape defined by the panels (10 2 -11 2 ) and thus ensures total tightness.
  • the membrane continues beyond into the reservoir in the usual manner according to known embodiments.
  • the membrane performs a double function, namely, ensuring the tightness of the reservoir and the adaptation of the interior volumes according to the pressures of the fluids in each of the tank chambers.
  • Figure 4 is illustrated the outline of the aarafaae- The flanges (10 4 -114) are turned 90 ° from their midpoint. Then in FIG. 5, the turning is complete and the staple closed. In Figure 6, any tool ensures the lifting of the clip (A) above along the wall (11 1 ) of the lower shell of the tank.
  • This stapling method obtained by the particular conformation of the ends of the walls of the tank is particularly advantageous and remarkably reduces the cost price manufacture of tanks. Tightness is guaranteed thanks to the new function given to the membrane.
  • This design adapts to all types of tanks, such as expansion tanks, expansion compensators, tanks for reserving pressurized fluids. These tanks can be of any shape and size.
  • the invention is in no way limited to that of its modes of application any more than to those of the embodiments of its various parts which have been more particularly indicated; on the contrary, it embraces all its variants.
