Description

PANEL FOR HYDRAULIC DISTRIBUTION IN AN INSTALLATION

The present invention relates to the field of devices for hydraulic distribution in installations. In particular, reference will be made to a panel-type device for facilitating the installation of the hydraulic network of an installation and in particular the riser of water. The present invention also relates to a water riser formed from an assembly of several panels according to the invention.

[Prior art] [0002] In the case of housing-type or office-type installations, the setting up of a new hydraulic network or the renovation of an existing hydraulic network requires the installation of a large number of pipes intended to manage the water network and especially a riser of water (eg cold water). The risers of water are vertical circulations in which the flow direction is upward (eg drinking water) or downstream (eg waste water) thus they constitute the backbone of the hydraulic distribution in buildings including housing. The cold water risers are collective pipes that serve water on each floor of a building and on which are connected the individual branches serving each dwelling or facility. [0003] The bringing into conformity of a hydraulic network and in particular of these risers of water in new installations of housing, office or building type generally requires taps, the shaping of pipes, or pipes, and must be done in according to an established regulation (eg in France NF DTU 60.1, DTU 60.1 1 and DTU 65.10). The shaping of these pipes consists mainly of the cutting, threading, bending and / or drilling of the tubes. These operations are generally carried out directly in the installations intended to receive the risers prior to assembly of the shaped elements. This assembly, depending on the nature of the pipes, can be done by screwing, solder-brazing, autogenous welding, capillary brazing, compression fitting, special connections, crimping fittings, flanges or stitching. Similarly, the pipes are fixed independently against the walls of the installation using stirrups or metal collars depending on the nature of the pipes. The regulation in some territories can very strict obliging the builders or the renovators imperatively respect precise dimensions, especially at the spacing between the columns and the support wall, between the nuts or between the counting stations. This shaping and this independent implementation of the different portions of pipes, directly on the site of the installation is very time-consuming. Thus, all these steps are time consuming and potentially accident generators. This is even more the case when building new housing buildings with a high number of floors. In addition, during the establishment of such distributions, there are occurrences of poor workmanship whose frequency is not negligible. In addition, the installation cost of these hydraulic distributions could be further reduced if these installations could be carried out by non-specialized persons, that is to say not being able to master the methods of cutting, threading, bending and / or or tube drilling as well as assembly techniques such as braze welding, autogenous welding or capillary brazing. It has already been proposed assemblies such as distributors (CH593394), compact (CH640290) or not, allowing, especially via a main pipe fixed at a rear wall and having bypass connections, to distribute the hydraulic flow ( EP2196584), or hydraulic units that can be interconnected (WO201 1029971). Nevertheless, there is no satisfactory solution to address the cost and risk issues associated with on-site shaping of the hydraulic system, including up-pipe. Thus, there is a need for new devices for rapid installation and without risk of hydraulic distribution of an installation.

[Technical problem]

The invention therefore aims to overcome the disadvantages of the prior art. In particular, the invention aims to provide a device and a method capable of responding to the problems associated with the construction costs and the risks associated with the on-site shaping of the hydraulic network, especially the rising pipe. This device and method also allow non-specialists to easily install a hydraulic network with a reduced occurrence of defects. [Brief description of the invention]

The invention provides a hydraulic distribution panel, also called prefabricated assembly or landing sheath, comprising the main parts necessary for the establishment of the distribution of a hydraulic network of a building storey, for example a building . For this purpose, the invention relates to a device for hydraulic distribution, preferably drinking water (eg cold water or hot water) or heating water, in an installation, characterized in that it is form of a panel comprising:

a main pipe comprising distribution outlets, preferably said main pipe being intended to form part of a water riser of the installation,

a plurality of secondary pipes connected directly or indirectly to the distribution outlets of said main pipe,

a plurality of valves capable of modifying or stopping a flow of water between the main pipe and each of the secondary pipes, and

a support on which the main pipe and the plurality of secondary pipes are fixed, said support being intended to be fixed against one of the walls of the installation.

With the aid of such a panel, since it already comprises valves, a main pipe having dispensing outlets, secondary pipes connected to a main pipe and these pipes are fixed on a support, a hydraulic distribution network can then be quickly installed on the site of the installation and save a significant time and a reduction of the risks of accident or malfunctions. This is all the more true regarding the installation of the common parts of a building hydraulic network requiring one or more valves to quickly isolate one of the dwellings. This is possible because a majority of pipe or tube design operations required for the distribution of water on a floor was carried out before installation on site for example in specialized workshops. In addition, such a prefabricated panel makes it possible to achieve a very small margin of error in the dimensions characterizing the arrangement of the pipes and therefore compliance with the regulations on the shaping of pipes.

[0009] According to other optional features of the panel:

the main pipe is advantageously intended to form part of a riser of water of an installation. This is particularly advantageous because the riser portions are particularly complex to handle and transform so as to design a functional and sustainable distribution network. In particular, the main pipe has a length of between 2 and 5 meters. Unlike prefabricated assemblies that can be used for setting up a distribution of water within a housing, the distribution panel according to the invention comprises a main pipe intended to form a portion of a riser of water from an installation. Thus the dimensions of this main pipe are much larger than for conventional applications.

the main pipe further comprises a valve. This allows for example to quickly isolate a floor or a set of rooms.

the main pipe has no elbow and is straight.

It has a main pipe or two main pipes.

It comprises between 2 and 20 secondary lines, preferably it comprises between 4 and 20 secondary lines and even more preferably between 8 and 20 secondary lines. The presence of this high number of secondary pipes allows the hydraulic distribution panel to distribute the water in a larger number of rooms or housing. Advantageously, the secondary lines comprise at each of their ends a removable connection means.

the support has an overall density of less than 700 kg / m ³ . This lighten the panel so as to facilitate its handling.

the support has at least one plate of rigid polymer material on which is disposed an expanded polymer. Advantageously, the support comprises at least one rigid polymer material plate with a density greater than 700 kg / m ³ on which is disposed an expanded polymer with a density of less than 700 kg / m ³ . This makes it possible to have a device for hydraulic distribution whose support is resistant while not being too heavy. In addition, the presence of the expanded polymer reduces vibration, related to the flow of fluids in the pipes, affecting the walls of the installation. Thus, it reduces the noise nuisance. Preferably, the support comprises two plates of rigid polymer material between which is disposed an expanded polymer.

the hardness of the surface of the rigid polymeric material plate is advantageously greater than 40 as measured by the ISO 868 standard.

the support comprises two plates made of rigid polymer material between which the expanded polymer is placed

the support has an area of between 0.5 m ² and 5 m ² , preferably between 2 m ² and 4 m ² . This surface for the support is sufficient to allow the fixing of the pipes on the support and ensure its rigidity while limiting the weight of the distribution panel hydraulic. In addition, the support may include recesses. Recesses in the support further reduce the weight of the panel.

the secondary ducts are fixed to the support by means of a fastening means, preferably of polymer material, consisting of at least two parts, a first part being able to fit into the support and a second part being adapted to maintain a secondary pipe between the first part and the second part and to be fixed detachably to the first part.

- The secondary pipes consist mainly of copper, steel or brass.

each of the secondary pipes is connected to a water meter, said water meter being connected to a distribution outlet of the main pipe.

According to another aspect, the invention relates to a method of manufacturing the distribution panel according to the invention. The manufacturing method comprises for example the following steps:

- cutting of the main pipe to the desired dimensions,

- Advantageously, installation at the ends of the main pipe connection means adapted to allow the sealed connection of the main pipe to another main pipe,

positioning and fixing of the distribution outlets on the main pipe, preferably by means of a welding step,

cutting of the plurality of secondary pipes to the desired dimensions,

advantageously, installation at the ends of the secondary lines of removable connection means,

installing a plurality of valves capable of modifying or stopping a flow of water between the main pipe and each of the secondary pipes, and

cutting the support to the desired dimensions, and

- Fixing the main and secondary pipes on the support.

[001 1] This method has the advantage of allowing the realization of all the design stages of a portion of a hydraulic distribution network of an installation in a workshop dedicated to the construction of these hydraulic distribution panels. Thus, all the steps of this process do not have to be carried out precariously on the site of the installation allowing a reduction of the cost, the defects and the risks of accident.

In another aspect, the invention relates to a water riser formed by a plurality of devices or panels according to the invention. For example, said riser is formed by a plurality of devices or panels according to the invention fixed one by one at their main pipe.

Other advantages and features of the invention will appear on reading the following description given by way of illustrative and non-limiting example, with reference to the appended figures which represent:

[Description of the invention]

In the remainder of the description, the term "substantially equal" means a value varying from less than 30% relative to the value compared, preferably less than 20%, even more preferably less than 10%. %.

By "installation" is meant a building or part of a building preferably comprising a plurality of floors and / or rooms.

The expression "water riser" or "water riser" corresponds, within the meaning of the invention, to a vertical duct in which the flow direction is ascending (eg drinking water) or descending (eg waste water), preferably ascending. This vertical pipe is able to supply water to each floor of a building and it comprises individual branches serving each dwelling or set of rooms. The main pipe according to the invention may constitute a portion or a rising pipe portion of water.

The term "removable", within the meaning of the invention corresponds to the ability to be detached, removed or dismounted easily without having to destroy attachment means or because there is no means of attachment is because the fixing means are easily and quickly removable (eg notch, screw, tongue, lug, clips, nut, thread). For example, removable, it should be understood that the object is not fixed by welding or by other means not provided to allow detaching the object. Advantageously, a removable connection means is a threaded connection or a recessed tube connection.

By "recovered water" or "collected water" must be understood as recovery water that is not distributed directly by the drinking water distribution network. This can be for example rainwater or gray water recovered at the facility or the water collected at an eco neighborhood.

The term "valve" in the sense of the invention corresponds to a manual or electrical device for changing or stopping the flow of water in a pipe (a tube or pipe) using an electrical signal or a mechanical action. It can for example integrate a solenoid or an electric motor. A valve according to the invention can also incorporate a probe (e.g. gate valve probe).

In the following description, the terms "upstream" and "downstream" refer to the direction of the flow of the fluid.

In the following description, the same references are used to designate the same elements.

Figure 1 shows schematically a device for the hydraulic distribution 1 according to the invention. The device 1 is advantageously in the form of a panel. Thus in the following description the device 1 may also be called panel 1. By panel, it is necessary to understand a support, preferably plane on which are fixed many elements. The panel according to the invention can be covered with a cover allowing to hide the arrangement pipes or hull limiting access to pipes and devices fixed to the support 10.

The device or panel 1 according to the invention allows in particular the rapid establishment of a hydraulic distribution on a floor of an installation. The installations may be industrial installations, office types, collective or domestic dwellings. Preferably, the facilities are buildings and even more preferably they are buildings with housing.

The hydraulic distribution is preferably a drinking water distribution, for example a distribution of cold potable water. However, the panel according to the invention can also be used for the establishment of a hot water distribution, a distribution of heating water or a distribution of water collected. Indeed, in large installations equipped with a centralized hot water production means, it is necessary to set up a hot water distribution network for each floor allowing a distribution of hot water to the entrance of the individual installation then to the points of drawing (eg shower, bath, sink, sink). In this context, the panel 1 according to the invention can allow a much faster implementation and with reduced risk of work accident.

As shown in Figures 1A and 1B, the hydraulic distribution panel 1 comprises a single main pipe 20, said main pipe 20 being preferably intended to form a portion of a riser water column. 'an installation.

Thus, in the context of the introduction of panels 1 according to the invention in a building, the sequence of several panels 1 (eg typically one panel per floor) can quickly form part of a column rising water capable of serving water each floor of a building and on which are connected the individual branches, via the secondary conduits 30, serving each dwelling. Since the main pipe 20 may be intended to form part of a water riser of an installation, the ends of the pipe 20 preferably comprise connecting means capable of allowing a connection of the upper end. the main pipe 20 of a panel 1 at the lower end of the main pipe 20 of another panel 1. The connection between two main lines 20 may for example be achieved via heterogeneous assemblies by adding metal, by polymerization of materials of the same nature and by crimping crimping.

Particularly when it is intended to form a rising column portion, the main pipe 20 generally has a length of between 2 and 5 meters, preferably between 2.5 and 4 meters. In this case, it usually has a diameter internally between 10 and 120 centimeters, preferably between 20 and 100 centimeters, more preferably between 25 and 85 centimeters. Such a diameter is particularly suitable for supporting speeds of the order of 1 m per second or higher and pressures of the order of 10 bars or more. For example, it may consist mainly of copper, steel such as galvanized steel, PVC or brass. Preferably, it consists mainly of copper and may include anti-corrosion treatment. In addition, when the main pipe 20 is intended to form a portion of the riser, it has no bend and is preferably straight. In addition, it is preferably intended to be positioned vertically in the installation.

In addition to its two ends, the main pipe 20 comprises a plurality of distribution outlets 23. These outlets are advantageously directly welded to the main pipe 20 and comprise at their end a removable connection means 24. For example, the main pipe 20 may comprise at least two distribution outlets 23, preferably at least three distribution outlets 23 and even more preferably at least four distribution outlets 23. The main pipe 20 shown in FIG. 1 comprises four distribution outlets 23.

The main pipe 20 advantageously comprises a valve 22 adapted to modify or stop the flow of water in the main pipe 20. This valve as shown in Figure 1 is preferably located at one end of the main pipe 20 and more preferred way of the lower part of the main pipe 20.

The main pipe 20 is fixed to the support by fastening means 21. These fixing means 21 will be adapted according to the load and the downward stresses and are preferably fasteners of threaded mechanical threaded type supported, if necessary, by a non-deformable metal frame.

In addition, the main pipe 20 may be coupled to a membrane ram device, an automatic air purger, or to isolation valves.

Figures 3A and 3B show the views respectively front and side of a hydraulic distribution panel 1 according to the invention wherein, said panel comprises two main lines 20 (20a, 20b). Note that these main pipes 20a, 20b, have a plugged end. In addition, these main pipes 20a, 20b have smaller dimensions such as for example a length of between 10 and 50 centimeters and an internal diameter of between 1 and 10 centimeters.

As shown in Figures 1A, 1B and 2, the distribution panel 1 comprises a plurality of secondary pipes 30. These secondary pipes 30 are generally intended to allow quantification and transport in an individualized manner. water to each dwelling of a floor. Thus, they constitute individual branches serving each housing, set of rooms or room.

The panel 1 comprises for example between two and twenty secondary lines 30. Figures 1A and 1B show, for simplification reasons, four secondary lines 30.

The secondary pipes 30 generally have a length of between 10 and 400 centimeters, preferably between 10 and 200 centimeters and an internal diameter of between 5 and 50 centimeters, preferably between 15 and 35 centimeters. However, as shown in Figures 3A and 3B, the secondary lines 30 may have a much smaller length, for example between 2 and 10 centimeters.

The secondary pipes 30 may consist mainly of copper, steel or brass. Preferably, they consist mainly of copper and may include anti-corrosion treatment. Thus, they add additional protection against the development of legionella in the hydraulic network of the facility, especially when the panel is used for hot water distribution. In addition, as shown in FIGS. 1A, 1B and 2, these secondary lines 30 advantageously comprise two perpendicular sections.

The hydraulic distribution panel 1 according to the invention also comprises a plurality of valves 25 able to modify or stop a flow of water between the main pipe 20 and each of the secondary pipes 30. More particularly, these valves 25 allow to modify or stop the flow of water leaving the secondary pipes (end 31, preferably with removable connection means). These valves 25 may be integrated in the main duct 20 or integrated in the secondary ducts 30. Advantageously, these valves 25 are positioned at the ends of the distribution outlets 23, at the end 32 (preferably with removable connection means). or at the end 31 (preferably with detachable connection means) of the secondary lines 30. They are then connected audite conduits removably.

Thus, the secondary pipes 30 are generally connected indirectly to the distribution outlets 23 of said main pipe 20. By indirectly, it should be understood that the panel may comprise devices such as actuators or measuring devices positioned between a pipe secondary and main pipe. Thus, many devices can be integrated with the panels according to the invention. The panel 1 according to the invention may for example further comprise water meters, solenoid valves flowmeters of temperature probes and / or calorimeters. In the case of a cold water distribution (for example FIGS. 1A, 1B, 2), the hydraulic distribution panel 1 according to the invention may comprise a cold water division meter 34 (FIG. B), with upstream valves 25 and downstream valves 26 for easy disassembly of the water meter 34, as well as an anti-pollution valve. As shown in FIG. 2, the anti-pollution valve 26 can act as a downstream valve. Said panel 1 may also include a pressure reducer preferably placed before the water meter 34. In the absence of a meter, the panel 1 may comprise a sleeve between the two removable connection means 24 and 32.

In the case of sanitary hot water distribution, there will generally be a water meter 34 and the upstream and downstream valves. Each of the secondary pipes 30 is then connected to a water meter 34, said water meter 34 being connectable to a distribution outlet 23 of the main pipe 20.

As shown in FIGS. 3A and 3B, in the case of the heating distribution, the hydraulic distribution panel 1 according to the invention may comprise 20a and 20b forward circuits, on the outgoing circuit 20a. To find a calorie counter (not shown) and a valve 25, it will be possible to find on the return circuit a gate valve probe 27 for measuring the return temperature, this probe can be connected to the calorie counter.

The secondary pipes 30 have two ends and advantageously they comprise at each of their ends a removable connection means 31, 32 for the one hand, for the removable connection means 31, a removable connection with conduits for for example, for the removable connection means 32, a removable connection with a water meter 34 or one of the distribution outlets 23. Advantageously, the means for removable connection 31 are positioned at an edge of the support 10 so as to facilitate their joining with a pipe.

Alternatively, the panel 1 may comprise one or more intermediate conduits, connected directly or indirectly to a distribution outlet 23 of the main pipe 20. By indirectly, it should be understood that the panel may comprise devices such as actuators or measuring devices positioned between a secondary pipe and the main pipe.

For example, each of the secondary pipes 30 may be connected to a water meter 34 and said water meter 34 is then connected to a distribution outlet of the at least one intermediate pipe. Such versatility makes it possible to respond to the diversity of layout needs and allows the easy and rapid implementation of a distribution network that best corresponds to the particular demand of the installation. In addition, the hydraulic distribution panel 1 comprises a support 10 on which are fixed the main pipe 20 and the plurality of secondary pipes 30 for example as shown in Figure 1. The support 10 is adapted to be fixed against one of the walls of the installation. Thus, the panel 1 with all these components can be directly installed without the usual operations of threading, bending, drilling or welding on site.

Advantageously, the support 10 has an overall density of less than 800 kg / m ³ . Preferably, its overall density is less than 700 kg / m ³ and more preferably its overall density or density is between 400 and 600 kg / m ³ . Such a density makes it easier to maneuver the device for the hydraulic distribution. Indeed, too high density causes too much weight of the panel 1 and makes handling difficult. In addition, a low density makes it difficult to handle the panel. Thus, the support 10 advantageously has an overall density greater than 300 kg / m ³ .

The thickness of the support is generally less than 20 mm. Preferably, it is between 5 mm and 15 mm. Even more preferably, it is substantially equal to 10 mm. Similarly, the control of the thickness makes it possible to obtain a sufficiently rigid support to support all of the pipes that it comprises while maintaining a weight that does not make its manipulation complex or trying.

As shown in Figures 4A and 4B, the support 10 advantageously comprises at least one rigid polymer material plate 1 1 on which is disposed an expanded polymer 12. In addition, the hardness of the surface of the plate of material The rigid polymer 1 1 is advantageously greater than 40 as measured by the ISO 868 standard, preferably the ISO 868: 2003 standard. Preferably, the hardness of the surface of the rigid polymeric material 1 1 is greater than or equal to 45. This surface hardness makes it possible to preserve a panel which is not very sensitive to scratches or to external minor damages, thus making it perfectly suitable for use in an environment of type construction / construction.

Advantageously, the rigid polymer material plate 1 1 and the expanded polymer 12 have different densities. The combination of these two polymers improves the properties of the support 10 and the panel 1 generally so as to provide a prefabricated assembly that is robust while being easily manipulated. For example, the rigid polymer material plate 1 1 has a density greater than 700 kg / m ³ , preferably greater than 800 kg / m ³ . The expanded polymer 12 has a density of less than 700 kg / m ³ , preferably less than 600 kg / m ³ . The density or density is preferably measured according to EN ISO 1,183-1.

Thus, the support 10 according to the invention according to these advantageous features allows the panel 1 to have net advantages in terms of weight compared to a conventional compact polypropylene panel whose density could be greater than 900 kg / m ³ . More from this, thanks to the above characteristics, the support 10 has an excellent ratio between toughness and high rigidity, strength and high resistance to chemicals or fire. In addition, it has higher stiffness and flexural strength than standard PVC panels.

The plate 1 1 rigid polymer material and the expanded polymer 12 may be composed of different polymers may for example be selected from: (meth) acrylic polymers (eg PMMA-polymethyl methacrylate), saturated polyesters (eg PET polyethylene terephthalate, polyethylene glycol PETG-polyterephthalate, PBT polybutylene terephthalate, PLA-polylactic acid), polyethylene (PE), polycarbonate (PC), polyvinyl chloride (PVC), polyvinylidene fluoride (PVDF), chlorinated PVC (CPVC), polyurethane (PU), polypropylene (PP). The rigid polymer material plate 1 1 and the expanded polymer 12 may also consist of copolymers.

Advantageously, and as shown in FIG. 4B, the support 10 comprises two plates made of rigid polymer material 11 between which an expanded polymer 12 is placed. This arrangement forms a sandwich-type structure in which the expanded polymer 12, a structure at lower density, is surrounded by one or more plates of rigid polymer material 1 1.

The support advantageously comprises several fixing holes 13 (generally at least 6) for quickly fixing the panel 1 to a wall. In addition, holes 14 may be provided to facilitate the attachment of the collectors on the support 10. Finally, the support may advantageously comprise recesses 15 to further reduce the weight of the panel 1 and thus facilitate its handling. In this case, the recesses advantageously have an area of between 500 cm ² and 7000 cm ² .

As shown in FIG. 1 and FIG. 2, the pipes 20, 30, 50 are advantageously fixed to the support 10 by means of fastening means 40.

Fastening means 40 having an advantageous structure are detailed in FIGS. 5A and 5B. Thus, advantageously, a fixing means 40 made of polymer is preferably composed of at least two parts 41, 45, a first part 41 being able to fit into the support 10, in particular via a protuberance 43. and a second portion 45 being adapted to maintain a duct between the first portion 41 and the second portion 45 and to removably attach to the first portion 41. As shown in FIGS. 5A and 5B, the fixing means 40 have a substantially flat shape. They comprise a hooking means 46 secured to the second portion 45 configured to be positioned, when closing the fastening means 40, in a housing 44 formed in the first part 41. When the second portion 45 is attached to the first portion 41, a location 42 corresponding to the outer diameter of a secondary duct 30 is formed and maintains said secondary duct 30.

In addition, as can be seen by comparing the fixing means 40 shown in FIG. 5A and that presented in FIG. 5B, the fastening means 40 can have different sizes so as to facilitate the organization of the conduits on the support. 10. It is then possible to make the support 10 different floors while maintaining the tubes attached to the support 10. Thus, advantageously, the panel 1 comprises fastening means 40 having different heights. The height values preferably having a difference of at least 2 centimeters, even more preferably at least 3 centimeters. For example, some fastening means 40 may have a height of between 70 and 90 centimeters while other fastening means 40 may have a height of between 40 and 60 centimeters. The fixing means 40 may also include a removable portion 47 that can be used to easily categorize the type of pipe to which the fastening means is associated.

The fixing means 40 are preferably made of rigid polymer material and may be composed of different polymers which may for example be selected from: (meth) acrylic polymers (eg PMMA-polymethylmethacrylate), saturated polyesters (eg PET-polyethylene terephthalate, PETG-polyethylene glycol terephthalate, PBT-polybutylene terephthalate, PLA-polylactic acid), polyethylene (PE), polycarbonate (PC), polyvinyl chloride (PVC), polyfluoride vinylidene (PVDF), chlorinated PVC (CPVC), polyurethane (PU), polypropylene (PP). The rigid polymer material plate 1 1 and the expanded polymer 12 may also consist of copolymers. The fixing means 40 may also consist of an assembly of rigid polymer and expanded polymer as described above.

The device for the hydraulic distribution 1 according to the invention may also comprise a pressure regulator. The pressure regulator may be positioned on the main pipe 20 or on a secondary pipe 30. Advantageously, the presence of this pressure regulator makes it possible, in particular, to counteract the increase in pressure at night or over the summer periods and thus significantly reduce the consumption. of water by the installation.

The permissible operating pressure within an individual installation is 3.5 bars because beyond the risk of deterioration of the diffusers (mixers, solenoid valves MAL ...) is not to be neglected. Lower pressure can only affect the comfort or performance of the hydraulic system. Thus, the pressure regulator is advantageously configured so as to maintain a pressure of 3.5 bar or less within the installation. Preferably, the pressure regulator is configured to maintain a pressure in the installation of between 3 bars and 3.5 bars.

Advantageously, the pressure regulator is a preset and automatic pressure regulator capable of automatically stabilizing the downstream pressure to a set value. Alternatively, the pressure regulator may comprise a pressure sensor with adjustable pressure reducer.

The device for hydraulic distribution 1 according to the invention is simple and quick to install in an installation, especially in a facility under construction. Fixing to the wall can be done by a simple hooking drilled to 10 mm. The ends of the pipes and the distribution outlets are then connected, preferably removably, for example following a system of pictograms.

With the panel 1 according to the invention it is possible to install a riser of a building in just one day while it could take more than a week with the systems of the prior art. In addition, the risk of accidents will have been reduced.

Because of all these advantages, it is possible to equip facilities in a simple, fast and less expensive than what was possible until now.
