Definitions

  • the invention relates to a special system of radiator production for heating plants, briefly consisting in the assembly of special basic elements which are easily obtainable using known means and processes.
  • the wide variety of possibilities of choice of basic elements enables obtaining a final product which includes radiators of considerably various sizes and shapes.
  • the simplicity and rapidity of the assembly operations of the various components of each single radiator further enables production of only the types of radiators requested and in the right numbers. This helps to avoid useless and expensive storage of finished products.
  • radiators which are normally used in water- and steam-operated heating plants to provide correct amounts of heat in rooms. These devices are generally constituted by hollow bodies having shapes and dimensions that vary, obtained with various materials and production processes; hot water, and in a few cases steam, both at low pressures, are made to run through these radiators; the water or steam are produced in boilers.
  • each element is made up of a number of tubular conduits, i.e. the columns, which are arranged coplanar as well as parallel to one another.
  • the elements connect at ends thereof to respective hollow bodies which constitute single manifolds.
  • Each of these manifolds is provided with holes for enabling reciprocal connection of several of the elements, by means of nipples.
  • the elements must be produced in various types, each type being basically characterised by a number and length of the columns it is made up of, so for each single type of element heating bodies, i.e. radiators, can be built having heat emission surfaces which are directly proportional to the number of elements assembled together.
  • One of the known solutions consists in forming a rectangular plate from a suitable steel sheet by a simple cutting and deep pressing process. A plurality of longitudinal recesses is pressed into the rectangular plate, which recesses are equi-distanced and parallel to one another, and are interconnected perpendicularly at ends thereof by further transversal recesses.
  • a finished radiator is obtained.
  • this process implies the use of a press for each type of radiator and therefore a considerable use of capital.
  • the welding operations are quite expensive, as they imply the use of special and expensive equipment and apparatus as well as further costly manual milling operations to remove the aesthetic defects resulting from the welding operations.
  • the problems of storage remain unsolved; indeed, they worsen.
  • a further known solution quite widely adopted, consists, once more, in using a steel sheet and cutting and shaping it by pressing into rectangular plates conformed in such a way as to develop two half-shells exhibiting some parallel longitudinal recesses orthogonally connected at ends thereof by respective transversal recesses.
  • Two half-shells obtained thus are arranged in opposite positions so that the longitudinal recesses and the transversal recesses form respective cavities equivalent to conduits corresponding to the columns and the manifolds of the elements mentioned above in the introduction hereto.
  • a further solution which is useful to the present summary due to a certain similarity with the solution of the invention is one which includes the use of lengths of cylindrical pipes which are welded at ends thereof; the hollow bodies having the “manifold” conformation.
  • These hollow bodies (“single manifolds”) are formed by two half-shells formed from suitable sheet steel, once more by cutting and pressing operations, which are welded to one another.
  • the main aim of the present invention is therefore to obviate the various above-described drawbacks, which aim is achieved by the new system of production of tubular radiators which includes, for the formation process of heating elements (radiators) of a tubular type, a simple and rapid assembly operation of hollow inter-connectable elements which are connected by threaded sleeves in order to develop manifolds of widely variable dimensions, to which lengths of cylindrical pipes of variable lengths are connected, the connection of the hollow elements to one another as well as their connection to the lengths of pipe being obtained without use of welding.

  • the half-shells 1 a, 1 b terminate inferiorly in a first short cylindrical tract 12 which is reduced by a suitable cylindrical amount determined by the cylindrical tracts 13 .

  • the cylindrical element 2 is constituted by a length of known common piping.
  • the sleeve 3 is externally formed as follows: it is composed of two consecutive cylinders 31 and 32 which decrease in diameter and terminate with a threaded tract 33 .
  • the first cylindrical tract 31 of the sleeve 3 is shorter than the following cylindrical tract 32 .
  • a further short threaded tract 33 follows the short cylindrical tract 32 .
  • the sleeve 3 is hollow; the hollow tract 31 a corresponding to the cylindrical tract 31 is internally threaded over the whole length of the tract 31 a, and then follows on within the cylindrical tract 32 with a hollow cylindrical part 32 a, while internally of the short threaded tract 33 there is a cavity with prismatic hexagonal shape 33 a.
  • the internal tract 31 a of the first cylindrical tract 31 has a female thread 33 which starts from the cylindrical tract 32 for reasons that will be explained herein below.
  • an elastic washer 4 is illustrated, formed from a ring provided at a circumferential part thereof with a brief interruption. Slightly-inclined short tracts 41 extend externally thereof.
  • FIGS. 24 to 26 an internally-hollow flange 5 is illustrated.
  • This flange 5 as shown in FIGS. 24 and 25 , has on one side thereof a short tract 51 provided with a hexagonal facing, and is very similar to normal nuts for bolts. It has an external mangle 52 and is preferably curved. The mantle 52 is interrupted by a flat circular surface 53 which is perpendicular thereto.

  • FIG. 24 shows that the thread of the externally-threaded part 54 starts internally of the curved mantle of FIG. 25 .
  • FIG. 26 shows that the flange 5 is internally provided with a thread 55 which begins at the same start point of the short tract 51 provided with a hexagonal facing. The thread 55 follows on at least up until the start of the externally threaded tract 54 .
  • the flange 5 is further provided with a rectangular groove 53 ′ for housing o-rings.
  • a second flange 7 very similar to the flange 5 , is illustrated.
  • the second flange 7 is different from the first flange 5 in that it does not have a threaded projecting part 54 but instead has a short externally cylindrical tract 71 .
  • the second flange 7 is also hollow, and is provided, as can be seen in FIG. 30 , with two threaded tracts 71 ′ and 72 having different diameters. More precisely, with reference to FIG. 30 , which is a section view according to lines VII-VII of FIG. 28 , the tract 71 ′ has a larger diameter and therefore a larger thread than the tract 72 which also begins line the threaded tract 52 of FIG. 25 in the same zone as the hexagonal tract.
  • the thread 72 ends at the threaded tract 71 ′.
  • the second flange 7 is interrupted by a circular flat surface 73 which is also provided with a groove 73 ′ for housing an o-ring.
  • FIGS. 1 and 32 which illustrate a preferred assembly of the above-described elements, the operator will first take the two half-shells 1 a, 1 b (illustrated in figures from 2 to 15 ), and before coupling them will carry out two operations.
  • a suitable glue such as a hard-wearing resin or the like on surface BA of the male half-shell 1 b.
  • the operator takes the two half-shells and joins them.
  • the coupling is done when the surfaces BA and BB are perfectly superposed and the resin is well-spread. Also the recess F of the female half-shell 1 b will meet perfectly with the projecting part M of the male half-shell 1 a and the pins Sa will engage precisely and solidly in the holes Fb.
  • the hollow element i.e. the radiator element 1 .
  • the pins Sa in the holes Fb have the aim of stiffening the radiator element 1 and preventing crushing thereof following the compression thereof during assembly.
  • the operator applies suitable o-rings in the recesses 14 and the elastic washers 4 in the recess 15 .
  • the operator screws together a flange 5 and a sleeve 3 , by engaging the external threaded part 54 of the flange 5 to the internal threaded part 31 a of the sleeve 3 , thus forming a single solidly-connected part.
  • the operator inserts in a radiator element 1 a first of a series of sleeves 3 coupled as above-described to the flange 5 , bringing the flange 5 to strike with the surface 53 thereof against the surface 11 of the radiator element 1 .
  • a first block of elements 5 , 3 and 1 is formed, the operator screws a second sleeve 3 to the previous sleeve 3 of the group consisting of elements 5 , 3 , 1 .
  • the operator uses a hexagonal key in the hollow part having a hexagonal section 35 and screws the sleeve 3 by the thread 31 a thereof, which sleeve 3 then engages with the thread 33 of another, preceding sleeve 3 .
  • a further o-ring O is then inserted in the cavity 11 ′ and a second radiator element 1 attached by repeating the previous stage of screwing a further sleeve 3 to the preceding sleeve 3 and in this way forming a plurality of sleeve-radiator-element couplings.
  • the flange 7 is used to close off the series of couplings, with the thread 71 ′ screwing onto the thread 33 of the sleeve 3 .

  • the lower cylindrical parts 13 are introduced simply by pressing the pipe 2 towards the cylindrical tract 12 of the radiator element 1 .
  • the pipe 2 strikes against the surface formed by the changed of section obtained by the difference of section in passing from the cylindrical tract 12 to the cylindrical part 13 , the pipe 2 is solidly coupled to the radiator element 1 .
  • This solid coupling is in effect a friction coupling between elastic washer 4 and the internal surface of the pipe 2 and can be observed in FIGS. 22 and 23 and relative large-scale representations.
  • FIG. 22 shows the lower circular part of the radiator element 1 , with the tracts 13 , 14 and 15 , detached from the pipe 2 and enlarged.
  • the elastic washer 4 with its projections 41 are shown, while FIG. 23 shows the following stage, i.e. the introduction of one of the lower cylindrical ends, which start from the lower cylindrical pipe 12 with the cylindrical tract 13 having a smaller section but having a larger section than the cylindrical tracts 14 and 15 internal thereof of the radiator element 1 in the pipe 2 , and the enlarged view of the detail of the elastic washer 4 indicates that the projections 41 flex and grip by friction, due to their elastic thrust onto the pipe 2 , i.e. against the internal surface of the pipe 2 .
  • the first described process (assembly of parts 5 - 3 - 1 and 3 - 1 with closure using the flange 7 ) is repeated at the other end of the pipe 2 with the series of radiator element 1 , sleeves 3 , flanges 5 and 7 forming a second “single block”.
  • identical threaded caps 6 ( FIGS. 27 and 31 ) are screwed on, by screwing one cap 6 by its thread 61 into the threaded part 55 of the flange 5 and another radiator cap 6 by its thread 61 into the thread 72 of the flange 7 .
  • Two flanges 5 and/or 7 will remain open in order to be connected, respectively, one to the water inlet pipe and the other to the radiator discharge pipe which will send the heating fluid into circulation.
