Description

The present invention relates to a hydraulic connection module intended for use in the field of real estate construction and more particularly in the field of sanitary and heating.

In the field of the construction of a building equipped with a boiler room supplying several apartments with domestic hot water and hot water for central heating, columns are installed in said building on which, for each of said apartments, we come to make taps in order to create individual circuits, which requires installing isolation valves and volumetric and energy meters, as well as carrying out hydraulic balancing.

In order to seek optimization, and above all to increase the living area, the space reserved for this equipment is to be combined in a preferably small space, which generates numerous drawbacks. Indeed, during connection and equipment operations, the installer must operate in this reduced space, so that, in addition to the difficulties of implementation, this presents the risk of poor connections and therefore of generating leaks.

We know, from the document WO 2019/048798 , a prefabricated hydraulic module, intended to divide the water distribution from a riser. This module thus comprises a main pipe on which are stitched secondary pipes. Such a module is more particularly intended for the distribution of a floor comprising several apartments. Moreover, as described, the main pipe constitutes part of the riser. Thus, apart from the fact that the module of this document is not intended for the same use, it does not solve the problem of bulkiness which the present invention seeks to remedy.

The same is true of the document WO 2011/029971 which also relates to a prefabricated hydraulic module intended for distribution to several dwellings, from a hot water pipe, a cold water pipe, and a heating circuit.

By document CH 640290 , we also know a prefabricated hydraulic kit comprising several taps in a box, only intended for the supply of sanitary cold water in a dwelling, but which does not provide any solution to solve the problem of bulk, if it were also to be question hot water and heating.

These documents all describe hydraulic modules intended to equip buildings, with a view to distributing water on one floor by floor to each of the apartments on this floor. They are therefore not intended for the same use, and therefore do not provide a solution to the problem of bulk.

The object of the present invention is to provide a hydraulic connection module making it possible not only to overcome the aforementioned drawbacks, but also to achieve a much greater optimization of space than what is currently obtained.

The hydraulic connection module according to the invention is intended for use in the field of building construction equipped with a boiler room supplying several apartments with water, domestic hot water and / or hot water for central heating is characterized in that that it consists of a single piece, which comprises a plate to which is secured a multiplicity of tubes, each intended to constitute an interface between an individualized circuit and a water column, each of said tubes comprising on the one hand a mouth of 'inlet intended to be assembled to a water column and an outlet mouth intended to be connected to an individualized circuit, and on the other hand an isolating valve of the individualized circuit, as well as, depending on the nature of the circuit, a volumetric and / or energy metering means; and in that the tubes are folded into a U, the U are arranged side by side in parallel or not parallel planes, their parallel branches perpendicularly crossing a plate of the plate through two holes, so that the inlet openings and outlet open on the other side of said plate.

According to an additional characteristic of the connection module according to the invention, each tube has a valve at each of its ends.

Such a module is intended to take place inside the apartment or in the corridor in front of the apartment in a cabinet or a technical shaft, it makes it possible to bring together in a small space all the equipment, the only operations carried out are the connections to the columns and to the individualized circuits, it is not necessary to equip the circuits on site with valves and other meters.

The U-shaped loops make it possible to reduce the size by at least 50% compared to a conventional assembly, and with a substantial saving in assembly time, in particular because all the components and accessories, valves and meters in particular, are assembled in the factory, accurately and tightly.

The module according to the invention can be installed on a wall with the hydraulic connections oriented downwards, to the right or to the left.

The only links between the hydraulic module and the apartment to be connected are only pipes without adding any components or accessories.

According to another additional characteristic of the connection module according to the invention, one of the holes through which pass the branches of one of the tubes bent in a U, is of oblong shape and in an arc of a center corresponding to the axis from the other hole.

According to another additional characteristic of the connection module according to the invention, the holes, intended to receive a U-shaped tube, are offset with respect to one another, and / or with respect to the holes of a neighboring tube.

According to another additional characteristic of the connection module according to the invention, the plate has at least one slot in its middle region.

The advantages and characteristics of the hydraulic connection module according to the invention will emerge more clearly from the description which follows and which relates to the appended drawing, which represents a non-limiting embodiment thereof.

In the attached drawing:

• the figure 1 represents a schematic perspective view of a hydraulic connection module according to the invention.
• the figures 2a, 2b and 2c represent schematic plan views of various embodiments of part of the module according to the invention.
• the figure 3 represents a partial schematic view in perspective of a variant of the module according to the invention.
• the figure 4 is a schematic representation of the hydraulic connection module of the figure 1 .

With reference to the figure 1 , it can be seen that a hydraulic connection module according to the invention is in the form of a part comprising on the one hand a plate 1 comprising, in this non-limiting embodiment, two walls, a horizontal lower wall 10 and a vertical rear wall 11 united at right angles to the wall 10, perforated at several points in order to be able to fix the hydraulic assembly on a wall or a fixed support; and on the other hand a multiplicity 2 of tubes 20 fixed to the plate 1 through suitable means, known per se, not shown.

The tubes 20, which can be made of all the materials usually used in the field, both metal and synthetic, and of diameters adapted to the desired and necessary flow rates, are bent in an inverted U to each form a loop, and are arranged one after the other. next to the others, the parallel branches 21 and 22 of the U, passing through the horizontal lower wall 10 of the plate 1 through holes 12 and 13 respectively, so that their end parts, intended for connections, open out on the other side of this wall 10.

It will be noted that in the middle region of the plate 10 is pierced a light 14, intended to facilitate viewing from above, of the zone located under the plate 10 and behind, directly above the wall 11.

All the tubes 20 are equipped with two V valves, one at each end part, positioned in this case above the lower wall 10, these V valves can be ball or plug, manually operated or motorized.

The tubes 20 include equipment such as in particular flow meters C, flow rate settings R.

The hydraulic connection module according to the invention allows a significant space saving. By way of non-limiting example, that represented on the figure 1 has the following dimensions: height 328mm, width 400mm and depth 166mm, which results in a footprint reduced to at least 50% compared to a traditional assembly.

Referring now to figures 2a, 2b and 2c , we can see variant embodiments of the plate 10.

On the figure 2a , the plate 10 conforms to that of the figure 1 , the front 12 and rear 13 holes are round and arranged at an equal distance two by two.

On the figure 2b , according to a variant, the holes 13 are each oblong and in an arc of a center corresponding to the axis of the hole 12 with which it shares the same U 20, not shown, so as to allow pivoting of the U around d 'a branch, and thus facilitate the connection as well as access to the valves V arranged at the rear.

It will be noted that it is perfectly possible that the holes 12 are oblong in shape, and also that only some are, and even that this concerns front holes 12 and rear holes 13.

On the figure 2c , we can see that holes 12 and 13 are round, but unlike those in the figure 2a , they are not evenly distributed bps, and in particular the rear holes 13. Thus, the holes 12 and 13, intended to accommodate a U-shaped tube, are not necessarily aligned parallel with the two holes 12 and 13 of a neighboring tube.

In a variant, they can also be aligned parallel but staggered, so as to obtain a favorable offset for access to the valves V of the tubes 20 arranged at the rear.

Of course, the variant embodiments shown on the figures 2a, 2b and 2c , are not limiting, and other combinations are possible.

It will be noted that it is possible, in order to optimize costs, for the tubes 20 to have only one valve V on one or the other of its ends. It is also possible that one or more tubes do not have a valve, if the local equipment already has one.

Referring now to the figure 3 , it can be seen that the hydraulic module according to the invention can be an integral part of a box 15. Thus the rear wall 11 constitutes the rear of this box 15, and the plate 10 is placed inside above a base 16, pierced with a large opening 17.

Furthermore, the box 15 is reclosable with a door 18.

• une entrée d'eau froide 3, comprenant deux vannes V et un compteur d'eau C,
• une sortie eau chaude sanitaire 4, comprenant deux vannes V et un compteur d'eau C, et associée à un bouclage d'eau chaude sanitaire 40 équipé d'une vanne V et d'un réglage de débit R,
• un départ chauffage 5, équipé de deux vannes V et d'un réglage de débit R, d'une prise de mesure de température D avec ou sans doigt de gant pour la sonde du compteur de calories,
• un retour chauffage 6 équipé de deux vannes V, d'un compteur C de calories et d'une vanne deux voies W avec moteur thermique pouvant être relié électriquement à un thermostat dans le logement (gestion du débit en fonction d'une consigne de température ambiante ou dispositif de présence).

The figure 4 represents a diagram corresponding to the nonlimiting embodiment shown in figure 1 , and we can see:

• a cold water inlet 3, comprising two valves V and a water meter C,
• a domestic hot water outlet 4, comprising two valves V and a water meter C, and associated with a domestic hot water circulation 40 equipped with a valve V and a flow rate adjustment R,
• a heating outlet 5, equipped with two valves V and a flow rate adjustment R, a temperature measurement point D with or without a thermowell for the calorie counter probe,
• a heating return 6 equipped with two valves V, a calorie counter C and a two-way valve W with heat engine that can be electrically connected to a thermostat in the home (flow management according to a temperature setpoint ambient or presence device).

The two-way valve W can also be fitted with an adjustable thermostatic head with capillary and copper bulb, copper bulb to be affixed to the pipe (mounted on a tube or in a thermowell) for heating flow or heating return ( flow management according to a desired leaving or return water temperature setpoint).

It should be noted that the heating flow or return pipe can be optionally fitted with a circulator instead of the two-way valve, to overcome, if necessary, excessively high pressure drops on the circuit of the room to be heated.

It is also possible, optionally, to provide a second heating circuit, identical to the first, with a motorized two-way valve or with a circulator instead of the two-way valve.

In these two options, this is achieved with or without a three-way or four-way motorized or thermostatic valve connected hydraulically, for temperature management of the heating circuit said to be discharged or mixed.

In the heating and domestic hot water circulation part, the flow rate is adjusted with a flowmeter with a transparent window, with a spring and ball positioned on the desired flow graduation. The adjustment is done simply with a screw which is part of this flowmeter, thus not requiring any digital measuring device.

The hydraulic connection module in the configuration shown can be 400mm wide, 420mm high and 170mm thick.

The hydraulic connection module not only saves space, but also saves time during installation.

In addition, all the leaktightness tests on the valves and meters will have been carried out in the factory.

Besides the fact that the embodiment shown is not limiting, it should be noted that the hydraulic module according to the invention can be installed in different positions both vertically and horizontally, so it can be oriented so that the valves V are positioned above or below, or sideways to the right or left, in front or behind.

Furthermore, the hydraulic connection module according to the invention may include other equipment than those shown. Thus, for example, the heating flow 5 and heating return 6 circuit can be equipped with a purge valve or an automatic purge.
