Definitions

  • the invention relates to a hydraulic connection assembly between a boiler and at least two circuits for using the hot water produced by this boiler.
  • Couples of two parallel branches are thus formed constituting the interface links with the circuits of use. These pairs of two parallel branches then develop in space to constitute the circuits of use.
  • the interface links formed by the two branches are connected, some of them hydraulically, when the operating circuit requires a mixture of the starting water with the entering water.
  • the offset increases the size of the boiler towards the rear.
  • the ideal consists in locating the lower ends of the interface branches in the same plane as the orifices of the distributors to which they are to be connected.
  • connection links must cross in the same plane. It then appears the physical need to dissociate them at the crossing point.
  • the object of the present invention is to remedy these drawbacks and to provide new advantages.
  • the invention relates to a set of hydraulic connections between a boiler and at least two use circuits from its inlet and outlet in hot water and from its interfaces for connection with the use circuits.
  • the present invention considerably simplifies the hydraulic connection of a boiler with its two operating circuits. It can be a radiator heating circuit and a domestic water heating circuit or two heating circuits, one by radiators, the other by floor.
  • the improvement comes from the simplicity of the means used which allow the installer to make the hydraulic connection in record time from already prepared assemblies.
  • the invention also makes it possible to significantly lower the total cost posed for the equipment in the boiler room.
  • the invention makes it possible to significantly reduce the size of the boiler room towards the rear.
  • the present invention applies to all types of heat transfer fluid boilers, either with conventional cast iron exchangers known as sectionable, or of another constitution.
  • the invention is not limited to the hydraulic connection of the boiler to a heating circuit by radiators and to a floor heating circuit but on the contrary extends to all the possible use circuits that it acts of domestic water heating or any other use. In addition, it is possible to envisage, as will be seen below, more than two circuits.
  • the boilers that can be used in the context of the invention all have a heating body 1 and at the rear a heated water outlet called hot water outlet 2 and a cold water inlet called return 3 conventionally located in the lower position. .
  • outlets and inlets 2, 3 are optionally extended by extensions 4, 5 each leading to a distributor 6 respectively for starting and returning 7.
  • the distributors used in the present invention comprise at least three channels, for some four channels or more depending on the number of circuits envisaged and of indicating or safety devices to be connected.
  • the body of the dispenser then develops along two adjacent sections 11 and 12 arranged for example at the same level, at an opening angle ⁇ not necessarily, but preferably obtuse, for example 120 °.
  • This angle value ⁇ allows the variant of Figure 5 to present a regular angular arrangement of opening angles equal to 120 ° between the different sections.
  • the adjacent sections 11 and 12 allow connection with the use circuits.
  • An additional section 16 can be provided between the two adjacent sections 11 and 12 for an auxiliary outlet 17, for example the boiler drain valve or a valve with safety discharge (not shown).
  • connection assembly consists of two distributors 6 and 7, various connections and at least two interfaces 18 and 19 with the circuits for using the boiler.
  • Each interface is specific to the operating circuit to which it is connected. It includes passive hydraulic elements and active hydraulic elements.
  • this may include a flow branch 20 coming from a channel of the flow distributor 6 and a return branch 21, for example hydraulically independent of the flow branch. In this case, it is held mechanically by a dry transverse branch 22 secured at each of its ends to one of the outgoing 20 and return 21 branches.
  • the outgoing branch 20 comprises a circulation pump 23.
  • the transverse branch 22 becomes hydraulically passable and a three-way type mixing valve is provided at its connection with the branch departure (case not shown for this interface).
  • Temperature indicators 24 and 25 for flow and return water as well as stop valves 26, 27 are further provided on each branch below the connections of the upper ends 28, 29 shown in FIG. 6 .
  • the interface 19 specific to the underfloor heating circuit will also include a flow branch 30 and a return branch 31. These will necessarily be hydraulically connected to each other by a transverse branch 32 leading to the flow branch 30 to a mixing valve 33 three tracks placed upstream of a circulation pump 34.
  • Water temperature indicators 35, 36 for flow and return water are also provided, as well as shut-off valves 37, 38 at the connections of the upper ends 39, 40 shown in FIG. 6.
  • the invention extends to the opposite case, that is to say one in which the interfaces are connected to the distributors by reversing the flexible connections. The latter then connect the outgoing distributor 6 to the outgoing branches 20 or 30 while the return branch 21 or 31 is each time connected by a rigid connection to the return distributor 7.
  • the invention allows a wide variety of presentations partially illustrated by the composite figure 6 relating only to the series with cross provision.
  • the omnidirectional junction 43, 44 existing between the starting branch 20, 30 of the interfaces, and the rigid connection 41, 42 with the starting distributor. As indicated, it is not a rotary joint, but a connection, for example, with a conical seat which allows before tightening of assembly to orient one part relative to the other. In the case of the variant, an omnidirectional connector 43 or 44 is provided at the bottom of each return branch 21 or 31.
  • This orientation is not angularly limited due to the deformable nature of the connection to the return distributor or to the departure distributor in order to provide many of the advantages mentioned above for the majority of them.
