OBJECT OF THE INVENTION

The invention, as stated in the present specification, refers to a modular discharge collection equipment for fire extinguishing agent cylinders, which has advantages and characteristics, which will be described in detail below, which represent an improvement of the current state of the art.

The object of the present invention focuses specifically on a collection equipment itself and the set of elements that are coupled thereto in order to collect the fire extinguishing agent contained in a group of cylinders or cylinders at 15 pressures of between 24 and 300 bars, to, at the time of unloading, drive it to the common pipe network of a distribution facility with the minimum loss of load, in particular of the fire extinguishing agent in an automatic fire installation, the which is distinguished by being modular in the sense of allowing to modify some factors of the same, among others, when presenting the collecting equipment a variable geometry in terms of number 20 and position of connection mouths that it has and when presenting the possibility of being able to vary its position thanks to the adjustable structure in which it fits.

FIELD OF APPLICATION OF THE INVENTION

 25

The scope of the present invention is part of the industry sector dedicated to the manufacture of fire-fighting equipment and installations.

BACKGROUND OF THE INVENTION

 30

It is known that, in fixed installations for extinguishing fires, there are certain risks in which it is more practical to use gas or water mist systems with cylinders, because they are more effective and cause less damage to the content to be protected. Said extinguishing agent is stored in cylinders at pressures ranging from 24 to 300 bars. These systems can be designed as modular installations where a single cylinder 35 is installed or as batteries where several cylinders connected in the discharge are installed by an element called "collector". This "collector" must collect the extinguishing agent from the cylinders and direct it to the pipes, but with the minimum possible head loss. In this case, the loss of pressure in a fluid due to the friction of the particles of the fluid between each other and against the walls of the pipe that leads them is called "pressure loss". Losses 40 may be continuous, along regular, or accidental or localized conduits, due to particular circumstances, such as a narrowing, a change of direction. In cylinder systems the loss of load and the reduction of flow are critical since they define the amount of extinguishing agent to be installed to protect a risk.

 Four. Five

The "manifold" is connected to the cylinders through a component called "hose", which is the conduit that leads the extinguishing agent from the valve outlet to the "manifold". The connection of the “hose” to the manifold is carried out by the check valve directly to the manifold that prevents the extinguishing agent from one cylinder from entering another, that is, it allows the passage of fluid in only one direction, from the cylinder to the manifold, not upside down. fifty

The problem that the present invention intends to solve is given by the fact that, until now, said distribution system contemplates the use of rigid elements that greatly limit the versatility of the installation, mainly due to the fact that the distance between

The check valves are fixed and the hoses have the same length.

Therefore, the distribution systems of these facilities usually have a collector of a length similar to the size of the battery, in which the connections of each conduit, coming from each cylinder, are arranged successively one after the other, so that, 5 the more cylinders it is intended to incorporate into the larger and longer system, the collector must be.

In addition in certain extinguishing agents, the minimum distance between the valve and the manifold, requires the use of rigid elbows, which increases the loss of load. 10

This manifold configuration forces the separation between cylinder and cylinder to be large enough to be able to install the hose from the valve mouth to the manifold connection. This means that the length of a battery, that is the size it occupies, is unnecessarily larger than desired. fifteen

All this, therefore, means that the capacity of fire extinguishing systems is greatly limited, usually due to the lack of space in the locations in which they are installed, since the cylinders must be placed in a row aligned one after the other and separated by certain space between them, so the inclusion of, for example, eight cylinders instead of four, which would double 20 the capacity of the fire extinguishing system, implies the need to have twice the space to install the distribution system with the tubular manifold.

It would be desirable, therefore, to have a more versatile distribution discharge manifold that allows the position of the cylinders to be modified and to reduce the space necessary for the connection of the pipes to the manifold, the object of the present invention being to provide said system. by developing the modular equipment that is proposed.

On the other hand, and as a reference to the state of the art, it is unknown the existence of any other modular discharge collection equipment for pressure fire extinguishing cylinders or invention of similar application that has similar technical, structural and 30 characteristics those presented by the one claimed here.

EXPLANATION OF THE INVENTION

The modular discharge collection equipment for fire extinguishing agent cylinders of the invention is thus configured as a remarkable novelty within its field of application, since according to its implementation the objectives previously indicated as suitable are satisfactorily achieved , the characterizing details making it possible and distinguishing it, conveniently set forth in the final claims accompanying the present specification. 40

Specifically, the equipment proposed by the invention, as noted above, is intended to be incorporated into a pressure extinguishing agent distribution installation, preferably a fire-fighting installation, but without limitation, in order to constitute the point where the extinguishing agent contained in pressure is collected in a group or battery of cylinders to drive it, from each of said cylinders to a common pipe of the distribution network, which, unlike known systems that limit the aligned position of the cylinders successively connected one after another to a common tube, it is distinguished by being modular, that is, it can be modulated since it allows modifying some factors thereof, preferably, to adapt the arrangement of the cylinders 50 occupying the minimum space, and to include the number of cylinders that best suits each case without the lack of space being an important imitation.

For this, the equipment of the invention comprises a manifold of geometry and number of variable connection nozzles, to which, in said mouths, each of the check valves, to which the pipes that carry the extinguishing agent are connected from the cylinder, these conduits being preferably constituted by flexible hoses, so that they can vary their position without affecting the discharge pressure, since, in addition, also preferably, the cylinders are provided with nozzles that directly reduce the outlet pressure of the extinguishing agent through the corresponding valve.

In addition, the manifold is coupled to an adjustable structure that allows, thanks to the flexibility of the hoses and the variable geometry of the manifold depending on the number of connection nozzles it has, to place said manifold at a point centered on the cylinder battery and at the height that best suits.

The described modular discharge collector equipment for fire extinguishing agent cylinders, therefore, consists of an innovative structure of unknown characteristics up to 15 now for the purpose to which it is intended, reasons that together with its practical utility, provide it with a sufficient foundation to obtain the privilege of exclusivity that is requested.

On the other hand, the example of figure 3 shows a manifold (2) with three connection nozzles (3) coupled in a protuberance (21) having three surfaces (22) oriented towards divergent points, whereby the space 10 which occupies said collector (2) is minimal. Logically, the collector can have various configurations, depending on the number of connection nozzles (3) it should have.

In addition, each cylinder (6) has a nozzle (7) of the type that reduces the outlet pressure of the extinguishing agent through the valve provided in said nozzle (7). Also, also preferably, the nozzles (7) of all cylinders (6) are connected in series by means of hoses (8) and to a pressure regulator (9).

On the other hand, it should be noted that the manifold (2) has anchors (10) that allow its fixation to an adjustable structure (11) that allows, thanks to the flexibility of the hoses 20 that constitute the conduits (5) of the extinguishing agent and to the variable geometry of the manifold (2), place said manifold (2) at a point centered on the cylinder battery (6) and adjust it to the height that suits them.

For this, preferably, said structure (11) comprises two parallel and vertical rails 25 on which a support consisting of two perpendicular segments to which the manifold (2) is anchored and which are screwed to the rails once the lane is fixed. collector height

In addition, the manifold (2) also has one or two upper jacks or mouths, at least one socket (4) where, preferably, a pressure switch is installed that gives signal 30 when the system trips and, optionally another (not shown) for the connection of an overpressure relief valve that is activated in case of overpressure in the discharge network.
