    Unidirectional check valve with several fluid inlets.
    OBJECT OF THE INVENTION
    The present invention relates to a one-way check valve with several fluid inlets.
    BACKGROUND OF THE INVENTION
    At present, the bottles containing extinguishing gas used in centralized fire extinguishing facilities, equipped with a battery of simultaneous discharge bottles, have unidirectional check valves in each bottle that allow the circulation of gas in the exit direction and prevent its return into the other bottles. The check valve of each bottle must be connected to a manifold that joins the flow of the gas during the discharge to direct it towards the pipe for later discharge in the room that is being protected, located above said bottles by means of sleeves arranged in vertical position and coupled at its ends to the manifold and the opening and closing valve of the corresponding bottle.
    For any type of fire extinguisher gas bottle battery, it is necessary to use a collection tube with the same number of entries as bottles form the system and consequently, the use of a check valve for each bottle.
    Then, the problem to be solved is the development of a unidirectional check valve, which can work in any position and that allows to reduce, simplify or dispense with the collector and the elements that are currently in each unit outlet, reducing the extra work, the accessories and leakage points as well as eliminating elements in cases like this! he allows it.

    The present invention is established and characterized in the independent claims, while the dependent claims describe other features thereof.
    The object of the invention is a unidirectional check valve for fluids to which several fluid inlets can be connected that converge in a single outlet. The technical problem to solve is to configure the valve with its components to reach the mentioned object.
    With "entries" is meant any type of conduction that introduces fluid into the valve. Specifically they can be conduits as set forth in the invention.
    An advantage of the valve is that it is a single piece, which makes it easy to handle and assemble in addition to the little place it occupies.
    Another advantage is that when integrated into a single body, leaks are avoided compared to many connections with many valves, where each connection is a potential leakage point.
    Another advantage is that you can work in any position, not only vertically, but in any spatial orientation.

    DETAILED EXHIBITION OF THE INVENTION
    A realization of the invention is shown below with support in the figures.
    Figure 1 represents a unidirectional check valve (1) with several inlets for fluids, both gases and liquids, comprising a body (1.1), usually of metal, solid in which there are practiced, usually by machining, at least two ducts of entry (1.2) of fluids that converge in a central cavity (1.3) from which a single outlet duct (1.4) for communication with the outside of the valve (1), each inlet duct (1.2) comprises a first cavity (1.21) from one side of the valve (1) to the beginning of a second cavity (1.22) as a continuation of the first (1.21) and of smaller diameter than it and that reaches the central cavity (1.3), being arranged inside from the first cavity (1.21) a helical spring (2) resting on one end against the face adjacent to the second cavity (1.22) and on the other end against a shutter (3), the spring (2) being housed inside of the shutter (3), which comprises holes (3.3) pa santes and a conical trunk portion (3.4) whose side face (3.41) leans against a lock washer (4) by the action of the spring (4) when the fluid pressure is lower than the thrust force of the spring, the washer being retained closing (4) by a retaining washer (5) arranged next to it, so that the fluid is retained in each inlet conduit (1.2) independently.
    That is, as regards the operation of the valve (1), it should be noted that each inlet duct (1.2) with its corresponding shutter (3), spring (4), lock washer (4) and retaining washer (5) , it works independently, they do the retention of the fluid independently, that is, it is only necessary that fluid enters through one of the inlet ducts (1.2) so that it works as it has been exposed and the fluid flows out through the outlet duct (1.4). Similarly, fluid can enter through more than one of the inlet ducts (1.2) and independent of its arrangement, for example, in a valve (1) of three inlet ducts (1.2), figures 1, 2 and 5, fluid can enter through the first and third, or the second and third. No matter how much fluid pressure there will always be for the

    duct through which it enters and towards the exit, it will never enter another inlet duct (1.2) as this is avoided by the retention made by the shutter (3) when closing against the lock washer (4).
    As can be seen in figures 1 and 3, the shutter (3) comprises a larger area (3.1) whose diameter is adjusted to the corresponding diameter of the first cavity (1.21) so that the fluid can only advance through the holes ( 3.3) and inside the shutter (3) when the pressure thereof overcomes the resistance of the spring (2), a smaller area (3.2) following the larger and smaller diameter than it.
    As can be seen in figure 3, the holes (3.3) of the shutter can be arranged between the major (3.1) and the minor (3.2), to favor the flow of fluid through them, and it can also be added that they are perpendicular to the longitudinal axis of the shutter (3).
    Preferably, the lock washer (4) is made of rubber, to ensure tightness.
    Optionally, as shown in Figures 2 and 3, the inlet ducts (1.2), the central cavity (1.3), the outlet duct (1.4) and the shutter (3) are circular in section, so machining is simple and fluid flow is favored.
    Optionally, as shown in the figures, the perimeter areas of the body (1.1) corresponding to the inlet ducts (1.2), and to the outlet duct (1.4) are flat faces and said ducts have a threaded portion starting therefrom, favoring the threading of sleeves, both inlet (6) and outlet (7), as shown in figure 8, exposing an installation of the valve (1) with gas bottles (8) as a fluid, this can be found in any case in gaseous or liquid form.
