Definitions

  • the present invention relates to a hydraulic connection device particularly for water-tube radiators.
  • flat-panel water-tube radiators have an upper connection assembly and a lower connection assembly which are hydraulically connected to each other by means of a connecting pipe.
  • the upper connection assembly is usually provided with a valve for adjusting the flow of water inside the radiator, whereas the lower connection assembly is hydraulically associated, by means of a distribution assembly, to the main hydraulic system for heating the building.
  • both the upper connection assembly and the lower connection assembly are produced by welding the various parts that compose them to each other or to a base for supporting them, in order to be able to obtain a low-cost product which can be modified at will according to requirements and to the various types of radiator available on the market.
  • weld testing causes the rejection of approximately 2% of manufactured parts.
  • connection nuts It is evident that the stress applied to the connection nuts is transferred entirely to the welded parts, and accordingly the previously tested welds are subjected to a torque which can damage them, making them leak without the possibility of performing any further check.
  • the aim of the present invention is to eliminate the above-noted drawbacks of the prior art.
  • an important object of the present invention is to provide a hydraulic connection device particularly for water-tube radiators in which the upper connection assembly and the lower connection assembly have a very small number of welds and in particular have a single weld for the upper connection assembly and for the lower connection assembly.
  • Another object of the present invention is to provide a hydraulic connection device particularly for water-tube radiators in which it is substantially possible to eliminate the steps for testing the welds in order to check for any leakage thereof, achieving substantially zero rejects.
  • Another object of the present invention is to provide a hydraulic connection device particularly for water-tube radiators in which the parts that compose the upper and lower connection assembly, even if subjected to intense torques, do not discharge these stresses onto any weld, accordingly ensuring absolute tightness of the various connection assembly parts and eliminating any operations for replacing the defective radiator during its installation.
  • Another object of the present invention is to provide a hydraulic connection device particularly for water-tube radiators which allows to paint the radiator without any problem, since it has a single welding region for the upper connection assembly and for the lower connection assembly.
  • Another object of the present invention is to provide a hydraulic connection device particularly for water-tube radiators which has an extremely low production cost since testing operations are minimized and production rejects are practically eliminated.
  • a hydraulic connection device particularly for water-tube radiators including an upper connection assembly and a lower connection assembly which are hydraulically connected to each other by means of a connecting pipe, characterized in that the upper connection assembly and/or the lower connection assembly include a manifold which is formed monolithically with a threaded part which is suitable for engagement with a complementary thread of a different member to which it is connected hermetically.
  • the hydraulic connection device particularly for water-tube radiators includes an upper connection assembly 2 and lower connection assembly 3 which are mutually hydraulically connected by means of a connecting pipe 4.
  • the upper connection assembly 2 and/or the lower connection assembly 3 include a manifold 5 which is formed monolithically with a threaded part which is suitable for engagement with a complementary thread of a different member to which it is connected hermetically.
  • the threaded part is a bush 7 with which a valve 50 is associated which is suitable for opening, closing or adjusting the circulation of water in the water-tube radiator.
  • connection assembly 3 the threaded part that forms a single body with the manifold is formed by a return coupling 8 which is subsequently hydraulically connected to the distribution assembly 51, partially shown in the drawings, and through this assembly to the main hydraulic system for heating the building.
  • the manifold 5 formed monolithically with the return coupling 8 has, in a substantially central portion, at least one first seat 9 which is suitable to engage a first complementary seat 10 formed in a plate-like support 11.
  • the seat 9 has at least two side walls which are substantially as high as the plate-like support 11 is thick.
  • the walls 12 of the seat 9 are furthermore conveniently straight and are parallel to each other and to the axis of the manifold 5, so as to ensure interference during coupling between the seat 9 and the complementary seat 10 provided in the plate-like supporting base 11.
  • the base has, at the end of the complementary seat 10, optional protrusions 52 which can be caulked so as to ensure a valid and stable connection of the manifold 5 and of the return coupling 8 to the plate-like supporting base 11.
  • the straight side walls 12 allow to insert the manifold in the complementary seat 10 so that the manifold is already orientated according to requirements.
  • the device further includes a delivery coupling 15 which is also formed monolithically with an upper enlarged portion 16.
  • a second seat 18 is furthermore formed between the delivery coupling 15 and the upper enlarged portion 16 and is suitable to engage a second complementary seat 19 formed in the plate-like support 11.
  • the second seat 18 and the corresponding second complementary seat 19 are respectively identical, in terms of both shape and structure, to the first seat 9 and the first complementary seat 10.
  • a first end 20 of the connecting pipe 4 is bent and suitable to be welded outside the region affected by the flow of water coaxially and internally with respect to the enlarged portion 16 formed monolithically with the delivery coupling 15.
  • the plate-like support 11 further has, in one of its regions, a protrusion 30 which is internally provided with a recess 31 which allows to receive the screw for connecting the side of the radiator directly to the plate-like support, accordingly eliminating any further work or parts for retaining the side on the body of the radiator.
  • the upper connection assembly 2 has a manifold 5 which is formed monolithically with the bush 7, with which the valve for adjusting the flow of water of the radiator is associated.
  • the manifold has, on the opposite side with respect to the bush 7, a cavity 34 which accommodates the second end 32 of the connecting pipe 4.
  • the seal of the valve 50 is preferably provided in this very region formed by the cavity 34 in two different manners.
  • the seal of the valve is provided directly inside a flared region 33 formed on the second end of the pipe 32, as shown in Figure 2.
  • the seal of the valve is provided directly inside the cavity 34, which is machined and shaped specifically for this purpose.
  • the only weld that is present in the upper connection assembly is the weld provided on the perimeter of the connecting pipe 4, and as mentioned the weld is not subjected to any kind of stress and by way of its very structure it makes testing unnecessary.
  • vent valve 35 which is suitable to vent air if any air is present in the piping of the system.
  • thread 60 of the delivery and return coupling can be provided internally and therefore be of the 1 ⁇ 2-inch size rather than of the 3 ⁇ 4-inch size, as shown in the drawings, in order to ensure protection thereof during handling and storage of the parts.
  • the device according to the present invention is particularly advantageous, in that welding of the various parts to the plate-like support has been eliminated and in that the manifolds are provided monolithically with the delivery coupling or the bush for receiving the valve.
  • the materials employed, as well as the dimensions, may be any according to requirements and the state of the art.
