    High sensitivity double clap non-return valve. The invention consists of a highly sensitive non-return valve, which is not affected in its operation by gravity, nor does it require elastic elements for its correct operation. For this, it is constituted from a base body (1) in which a control volume (8) is defined, as well as two clappers (4 and 5) located inside the base body (1) for entry and exit. of the fluid, clappers that are mounted on the same axis (6) integral with both clappers and supported at their ends through separate covers (2) and (3) for the base body (1). The clappers (4 and 5) are able to make a turn both clockwise and counterclockwise, to establish the position of fluid inlet towards the control volume (8) with outlet closure, when the pressure in the control volume is less than the outside pressure or to block the inlet to the control volume and allow the outlet to the outside when the pressure in the control volume is greater than the outside pressure.

    [0002] HIGH-SENSITIVITY DOUBLE CLAPETE ANTI-RETURN VALVE
    [0003]
    [0004] OBJECT OF THE INVENTION
    [0005]
    [0006] The present invention relates to a high sensitivity double clap non-return valve, intended to control the air transfer between a control volume and the exterior, such that the control volume and the exterior are connected precisely by means of the valve of the invention, which is provided with two holes that communicate with the outside and two others that communicate with the control volume. One of these holes is always an exit and the other is always an entrance.
    [0007]
    [0008] The valve of the invention is applicable in different sectors such as underwater, rescue, toxic atmospheres, fluid pumping, assisted respiration, valves for sanitary use and others.
    [0009]
    [0010] The object of the invention is to provide a non-return valve with high sensitivity in its operation, which is not affected in said operation by gravity, nor does it require elastic elements that require minimum pressure levels maintained for its correct operation.
    [0011]
    [0012] BACKGROUND OF THE INVENTION
    [0013]
    [0014] The non-return valves currently on the market require a pressure gradient to activate their opening, so that in order to close, the disappearance or inversion of such a pressure gradient is necessary.
    [0015]
    [0016] In this sense, there are non-return valves that work in a gravitational way, so that they store energy or are blocked when there is a pressure gradient, and they are released when said gradient ceases. These valves have elements that rise and return to their initial position when the pressure gradient disappears.
    [0017] The oscillating clapper valves store elastic energy, having elements such as springs or diaphragms that allow their operation without depending on gravity, as in the case previously described.
    [0018]
    [0019] However, in this type of valve the pressure gradient must be kept above the elastic resistance offered by the material.
    [0020]
    [0021] In another group of non-return valves are the piston or ball valves that, in addition to being affected by gravity, may be additionally assisted by elastic elements such as springs, with the limitations described above.
    [0022]
    [0023] In either case the valves described are structurally complex and most importantly, their reliability and operation is limited by a minimum maintained pressure gradient that must at all times overcome the gravity or elasticity of a material to be actuated.
    [0024]
    [0025] DESCRIPTION OF THE INVENTION
    [0026]
    [0027] The highly sensitive double clapper non-return valve, which is recommended, has a series of characteristics that solve the problems of conventional non-return valves, resulting in a simple, more precise valve, with lower pressure gradients and that does not need hold gradient to keep valve actuated.
    [0028]
    [0029] For this, and more specifically, the valve of the invention is constituted from a base body in which two holes are established for the location of two clappers that are mounted on the same axis, the ends of which support inner lids. and external, from the base body itself.
    [0030] The flaps can rotate both clockwise and anti-clockwise, always in solidarity to add the efforts, so that in one direction as well as in the other one of the flaps performs, for example, the closing of the entrance hole from the outside to the control volume, allowing the exit through the exit orifice, or allowing the entrance to the control volume from outside, closing its exit and opening the entrance orifice. In all cases the entrance of fluid from the outside to the control volume is It is made through the inlet port and the fluid outlet from the control volume is done through the outlet port.
    [0031]
    [0032] The operating principle of the valve is based on the pressure difference between the control volume and the external pressure, so that when the external pressure is greater than the pressure within the control volume, the clappers that make up the closing mechanism They rotate a certain angle counterclockwise, allowing fluid to enter through the inlet and blocking the entry of fluid from the outlet, while when the outside pressure is less than the pressure Within the control volume, then the closure system rotates a certain angle clockwise, allowing fluid to escape to the outlet and blocking the flow of fluid to the inlet.
    [0033]
    [0034] In this way, an anti-return valve is obtained with a high sensitivity in its operation, which is not affected in its operation by gravity, nor does it require elastic elements that limit the pressure or minimum pressure levels for its correct operation. In addition to not requiring a maintained pressure gradient for the valve to maintain its state, either open or close.

    [0063] PREFERRED EMBODIMENT OF THE INVENTION
    [0064]
    [0065] In view of the outlined figures, it can be seen how the high sensitivity double clapper check valve object of the present application comprises a base body (1), with two covers, an external cover (2) and an internal cover (3), base body (1) inside which two clappers (4) and (5) are mounted, which can rotate with respect to a common axis (6) when that both are in solidarity, said claps being out of phase with each other.
    [0066]
    [0067] More specifically, in the base body (1) two chambers are defined on either side of it in which the clappers (4) and (5) play, and which are closed by the outer (2) and inner covers (3), chambers that communicate with each other through a central hole (1 ') through which the hollow central and cylindrical body (4'-5') of both clappers is tightly passed through.
    [0068]
    [0069] In this way, the clapper (4) associated with the face and consequently the outer cover (2) of the device communicates through the internal hollow of its central and cylindrical body (4 ') with the inlet (10) provided for the valve, acting as a communication link with the second clapper (5) through the hollow of its central and cylindrical body (5 '), which has holes (5' ') that communicate the inlet mouth with the inner chamber of the main body (1) in which conduits are defined to a control volume (8), control volume (8) that will also communicate with the outer chamber of the main body (1) in which the clapper (4) plays , and in which pipes are defined that communicate with respective outlets (9) provided in the outer cover (2).
    [0070]
    [0071] Thus, the offset between clappers (4) and (5) is such that when the clapper (4) is in the open position, that is to say allowing the admission of fluid through the inlet mouth (10) towards the volume of control (8), the clapper (5) blocks the output of said control volume towards the outlet ports (9).
    [0072]
    [0073] In figure 3 the clapper (5) is shown and in figure 4 the clapper (4), so that in correspondence with the central core (5 ') of clapper (5) the inlet mouth (10) is established towards the corresponding control volume (8) established in the valve body itself (1), so that, returning again to figure 4, the clapper (4) is capable of rotating an angle a through which the volume of control (8) with two outlet ports (9), or rotate counterclockwise to block said control volume (8).
    [0074]
    [0075] Thus, and as shown schematically in Figure 5B, when the pressure outside the outlet mouth (9) is greater than the pressure inside the control volume (8) so the closing mechanism rotates an angle a counterclockwise, allowing the entry of fluid from the outlet inlet (10), and blocking the entry of fluid from the outlet.
    [0076]
    [0077] On the other hand, when the external pressure, that is to say at the outlet mouth (9) is less than the pressure inside the control volume, then the closing mechanism rotates an angle a clockwise, allowing the outlet of the fluid contained in the control volume (8) towards the outlet mouth (9), as shown in figure 6B.
    [0078]
    [0079] The device thus described always performs the absorption of the fluid through the inlet mouth (10) and expels it through the outlet mouth (9), preventing the flow of fluid through the inlet mouth (10) and the entry of fluid through the outlet mouth (9).
    [0080]
    [0081] Schematic representations of fluid inlet and outlet operation are shown in Figures 7, 8, 9, and 10.
    [0082]
    [0083] Thus, figure 7 shows the air inlet flow in the intake position and in figure 8 the blockage of air inlet flow through the outlet mouth.
    [0084]
    [0085] That is, when the external pressure in the inlet mouth (10) is greater than the pressure in the control volume (8), the position of the clapper (5) allows the entry of fluid through the inlet mouth (10 ), while in figure 8 it can be seen how when the external pressure in the outlet mouth (9) is greater than the pressure in the control volume (8), then the position of the clapper (5) prevents entry of fluid through the outlet (9).
    [0086]
    [0087] However, in Figures 9 and 10, the outlet flow blockage through the inlet mouth (10) and the air outlet in the expulsion position are shown, respectively. In other words, when the external pressure in the inlet mouth (10) is less than the pressure in the control volume (8), then the clapper (5) prevents the fluid from leaving the inlet mouth (10), while when the external pressure in the outlet port (9) is less than the pressure in the control volume (8), then the position of the clapper (4) allows the fluid to exit through the outlet port (9) .
    [0088] In this way, a highly sensitive valve is achieved, since the pressure difference between the control volume and the exterior that actuates the double clapper is very low, to which must be added the fact that the only point of support of the The ends of the shaft are closed, the weight being very low, the mechanism being perfectly balanced.
    [0089]
    [0090] Although and as previously mentioned the valve thus described can have multiple applications, one of said applications could be breathing in toxic atmospheres, in the absence of oxygen or under water, so that, by adding a second control volume, The problems of fogging in helmets where this type of valve would be implantable to control the user's breathing could be solved.
