Definitions

  • This invention concerns a connector for tubular elements for the conveying of fluids.
  • this invention is a fitting of the type comprising at least one ring nut and a ring which are coupled to a terminal portion of a hydraulic device.
  • fittings are known for tubular elements for the conveying of fluids. It is well known that, in hydraulic distribution systems, the critical points are constituted by the connection points between the tubular elements of the plant, in particular, between the various pipes, between them and the valves, fittings or junction devices in general. The connections usually occur by means of ring nuts that fit into the end portions of these tubular elements.
  • These well-known fittings mainly have the drawbacks of being made up of two pieces: a ring nut and a ring. This may involve, in the mounting and disassembly phases, the detachment of the two pieces for which the ring often falls to the ground.
  • This invention obviates the above mentioned drawbacks by providing a ring nut and ring assembly, bonded to each other in a stable and safe way.
  • the subject of this invention is a connector for tubular elements for the conveying of fluids with the features of the attached claim 1.
  • Figure 1 shows a side view of the connector according to this invention
  • Figure 2 is a top view of the connector according to this invention.
  • Figure 3 shows a section of the connector taken along the line A-A of Figure 2;
  • Figure 5 shows an exploded side view of the connector according to this invention
  • Figure 6 shows a top view of the connector according to this invention.
  • Figure 7 shows an exploded section of the connector taken along the line B-B of Figure 6;
  • Figure 8 shows a detail of the connector indicated in the circle in Figure 7;
  • Figure 9 shows a perspective view of the connector according to this invention.
  • Figure 10 shows a perspective exploded view of the connector according to this invention in the assembly phase.
  • connector 1 comprises a ring nut 2 and a ring 3 provided with a notch 4.
  • the ring nut 2 comprises an upper annular sector 21 and an external thread 22 via which the connector connects to a complementary inner thread 222 of a hydraulic device 223 (for example, a junction, a cap, a solenoid valve, etc.) possibly provided with an identification ring 7.
  • Said ring 3 is inserted in the lower end part of the ring nut 2 and is able to clutch on to the tubular element.
  • the lower end portion 23 of the ring nut 2 is internally shaped as a truncated cone that widens towards the lower edge.
  • the ring 3 is, preferably, in its external part, of frusto-conical shape substantially complementary to that of the ring nut.
  • Said ring 3 is also provided with an external annular rim 31 that goes to seat tightly into a corresponding internal annular rim 24 provided inside the ring nut 2 and, in particular, in its frusto-conical portion 23. In this way, the ring 3 and the ring nut 2 always remain bonded to one another.
  • the ring 3 is also provided with an upper edge 33 that rests against the terminal edge 25 of the lower part of the ring nut and is provided with internal teeth 34 which clutch on to the tubular element to lock it inside the connector.
  • the ring 3 abuts on the inner edge 224 of the hydraulic device 223, fitted with a gasket 6.
  • the width of the notch 4 of the ring is determined according to the actual need of the tube clamping and is determined according to the circumference of the pipe and its thickness; the penetration of the teeth 34 in the pipe varies W between 0.5 and 1 mm.
  • the predetermined notch width allows you not to change, in a permanent way, the circumference of the ring. In this configuration, to mount the assembly in a safe way, it is not necessary to exert excessive force on the ring nut because, as already said, it is the very same liquid pressure on the walls which brings about a strong and secure clamping.
  • the assembly of this invention is able to withstand a pressure up to 700 bars, without the pipe slipping off.
