    [0002] Mechanical valve for fluids
    [0004] Technique sector.
    [0006] This invention is applicable in the field dedicated to the manufacture of valves for opening, closing and regulating the flow of fluids and, more specifically, of mechanical regulating valves for the supply of liquid or gaseous fluids.
    [0008] Prior state of the art
    [0010] Different valves are currently known for regulating fluid flow rates.
    [0012] Specifically, in the international application WO 2011/009793 a valve composed of several plates with different sized holes is described, to make a gaseous fluid pass between them, producing the gas outlet regulation.
    [0014] The drawback of this valve is that it has a high mechanical complexity.
    [0016] Patent ES 2 552 586 A1 describes a gas regulating valve for a cooking point provided with a valve body housed in the valve housing, with the possibility of turning in a predetermined direction from a closed position to a position open and where the valve body can continue to be rotated in the predetermined direction of rotation beyond the open position to a low combustion position, and where the gas flow through the valve is continuously adjustable, by rotating the body from the open position to the low burn position.
    [0018] In this type of valve, the regulation of the fluid is carried out in a practically intuitive way by turning the valve body, but it does not have predetermined opening positions in which the valve supplies predetermined flow rates of fluid.
    [0019] In document US 5 009 393 a linear reduction metering valve for gaseous fuels is described comprising a valve body provided with a frusto-conical chamber receiving a rotatable plug and including a radial inlet and an axial outlet at an end opposite to a control shaft. In this case, the passage of gas through the valve is determined by elongated holes that allow the gas flow to increase linearly as the control shaft is rotated.
    [0021] As in the previous antecedent, this valve does not have certain opening positions in which the supply of predetermined flow rates of fluid takes place.
    [0023] The mechanical regulation valves on the market have the drawback of not allowing a complete regulation of the valve with the rotation of a spindle that moves an internal regulator in charge of controlling the flow of fluid supplied. This is due to the fact that the part positioned on the spindle is frusto-conical.
    [0025] Explanation of the invention
    [0027] The mechanical valve for fluids that is the object of this invention is of the type described in the preamble of claim 1, and has constructive features aimed at supplying predetermined flow rates of fluid in predetermined opening positions of the valve allowing, therefore, a controlled delivery of the flow through the choice of the determined position, instead of the linear opening and without a specific control of the flow that the current valves allow.
    [0029] The valve of the invention also has characteristics aimed at allowing the valve to pass directly from a closed position to a position of maximum opening, or minimum opening, without passing through any intermediate opening position.
    [0031] Another objective of the invention is to simplify its construction avoiding the use of cavities and frusto-conical shutters.
    [0033] Another objective of the invention is to allow the supply of flow rates Selectable presets by means of the valve opening positions, making it a valve especially suitable for different uses, such as: general industrial uses, flow regulation in precision laboratory devices, precise regulation in low pressure micro regulation, water taps , pneumatic or hydraulic equipment, large fluid distribution lines, regulation of the supply of industrial gas to burners, regulation of gas bottles for use in welding or medicine, or other consumer equipment.
    [0035] Therefore, one of the notable advantages of this valve is that it allows precise and repetitive regulation in each of the opening positions, by means of a purely mechanical solution, which does not require electronic control, for said precise and repetitive flow regulation.
    [0037] The mechanical valve for fluids, object of this invention, comprises a valve body provided with a fluid inlet port, a fluid outlet port and a cylindrical inner passage for the communication of said inlet and outlet ports, and a stem provided with an end housed in the interior passage of the valve with the possibility of turning between: an opening position in which it allows a passage of fluid between the inlet and outlet ports and a closed position in which it prevents the passage of fluid.
    [0039] In order to achieve the aforementioned objectives, the stem comprises a hollow tubular section housed in a tight manner, with the possibility of turning in the interior passage of the valve body.
    [0041] Said tubular section comprises: an internal cavity for the circulation of fluid in an open position of the valve and which is kept in permanent communication with the fluid inlet mouth of the valve body; radial fluid outlet mouths, of different sections, distributed circumferentially in the tubular section and arranged in correspondence with different opening positions of the stem, forming an alignment of radial mouths of increasing section, suitable to face the outlet mouth of the body of the valve in successive angular positions of the stem, and provide different flow rates of fluid, and a closing portion, which faces the fluid outlet port in a determined angular position of the stem, closing the fluid passage.
    [0042] By rotating the stem and positioning it in different opening positions, the respective radial fluid outlet ports are confronted with the outlet port of the valve body and, consequently, the passage of the fluid flow determined by the pressure of the corresponding mouth.
    [0044] The cylindrical configuration, both of the interior passage of the valve body and of the hollow tubular section of the stem, significantly simplifies the manufacture of the valve and the cost of the same.
    [0046] Another relevant characteristic of the invention is that the closing portion of the tubular section of the stem is arranged between the two radial openings, with the largest and smallest section of the tubular section of the stem, said stem being able to rotate in two opposite directions, so that said stem can pass directly from the valve's closed position to a position of maximum opening, or minimum opening of the valve, by means of a limited angular displacement and without the need to pass through any of the other intermediate opening positions.
    [0048] According to the invention, the interior cavity of the stem comprises, for its maintenance in permanent communication with the fluid inlet mouth of the valve body, radial windows located in a circular arrangement in the hollow tubular section of the stem and spaced apart axial direction of the alignment of radial fluid outlet nozzles.
    [0050] These radial windows are dimensioned in such a way that, regardless of the position of rotation of the stem, they keep the fluid inlet of the valve in permanent communication with the interior cavity of the cylindrical body of the stem.
    [0052] It should be mentioned that the rotation of the stem, to arrange it in any of the open positions or in the closed position, can be carried out manually or motorized.
    [0054] Brief description of the content of the drawings.
    [0056] To complement the description that is being made and in order to facilitate the understanding of the characteristics of the invention, a set of drawings is attached to the present specification in which, by way of illustration and not limitation, the following has been represented:
    [0058] - Figure 1 shows a schematic elevation view of an embodiment of the mechanical valve for fluids according to the invention, sectioned along a vertical plane and with the stem in a closed position.
    [0060] - Figure 2 shows a view similar to the previous one with the stem in one of the opening positions.
    [0062] - Figure 3 corresponds to a section of the valve of the previous figures by the plane A-A marked in figure 1.
    [0064] - Figure 4 shows a diagram of the different flow rates provided by the valve in the different opening positions, represented by the references of the corresponding mouths.
    [0066] Detailed exposition of embodiments of the invention.
    [0068] In the embodiment shown in the attached figures, the valve comprises a body (1) provided with an inlet mouth (11), an outlet mouth (12) and an inner passage (13) of cylindrical configuration for the communication of the inlet (11) and outlet (12) ports.
    [0070] The valve comprises a stem (2) that has a tubular section (21) housed in the inner passage (13) of the body (1), with the possibility of turning in two opposite directions and without the possibility of displacement in the axial direction, the end protruding (22) opposite of the stem of the body (1) for its rotary actuation and its arrangement in a closed position or in various open positions of the valve.
    [0072] The inlet mouth (11) and the outlet mouth (12) of the body (1) are spaced in an axial direction with respect to the inner passage (13) of the body (1) and, in this embodiment, diametrically opposed.
    [0073] The tubular section (21) of the stem (2) has an internal cavity for the circulation of the fluid when the valve is in an open position.
    [0075] The tubular section (21) of the stem (2) comprises radial windows (24) that permanently communicate the interior cavity (23) of the stem (2) with the inlet mouth (11) of the body (1) of the valve.
    [0077] The tubular section (21) of the stem also has radial openings (25a, 25b, 25c, 25d, 25e) of different sections distributed circumferentially in the tubular section (21) of the stem and ordered by section, as shown in the figure 3.
    [0079] Said radial ports (25a - 25e) form an alignment and are angularly spaced defining successive opening positions in which they individually face the fluid outlet port (12) of the valve body (1).
    [0081] The tubular section (21) of the stem has between the openings (25a - 25e) of greater and lesser section a continuous closure portion, which in a certain angular position of the stem (2), specifically the one represented in Figures 1 and 3 , faces the fluid outlet mouth closing the valve the fluid passage.
    [0083] As mentioned above, starting from the closed position represented in figure 3, it is enough to turn the stem (2) in one direction or the other so that the valve passes from a position of maximum opening, when facing the radial mouth ( 25e) of greater section with the outlet mouth (12) of the valve body, or to a position of minimum opening, when the radial mouth (25a) of smaller section faces the outlet (12a) of the body (1) from valvule.
    [0085] As can be seen in Figures 1 and 2, the inlet mouth (11) of the valve body (1) and the radial windows (24) of the tubular section (21) of the stem (2) are located in a plane spaced longitudinally with respect to the plane defined by the radial outlets (25a-25e) of the stem (2) and the outlet (12) of the valve body (1).
    [0086] As can be seen in Figure 4, in the different valve opening positions, obtained by confronting the successive radial ports (25a, 25b, 25c, 25d and 25e) with the outlet port (12) of the body ( 1), the valve provides a predetermined flow rate of fluid for each of said ports (25a-25e).
