    [0003]
    [0004] The present invention relates to a pivoting valve to regulate the flow of a fluid. It also refers to a procedure for regulating the flow of a fluid by means of the valve object of the invention.
    [0005]
    [0006] Background of the Invention
    [0007]
    [0008] The problems of pressure loss caused by the different elements that comprise a fluid installation, such as valves, sudden widening and narrowing, elbows or "T" type connections, among others, are known in the state of the art. These pressure losses must be considered during the design phase of the installation, conditioning the dimensioning of the hydraulic pumps.
    [0009]
    [0010] Valves in fluid installations usually have a sealing element that can be totally or partially open to regulate the flow of fluid, so that it causes variable pressure losses. Valves of different types are known in the state of the art, such as, for example, butterfly valves, tap valves, non-return valves, or poppet valves, among others. This type of valve has the drawback that in the open position, the plug is arranged in the path of the passage of the fluid flow, so that it creates significant pressure losses. Furthermore, as the plug element is exposed to the flow of the fluid, it must be designed in such a way that it is able to resist the forces exerted by said fluid, sometimes causing oversizing of the valve plug element.
    [0011]
    [0012] In the state of the art valves are known where the sealing element is located outside the passage of the fluid flow, positioning itself in a cavity of the valve body, in this way the orifice is free of obstacles. This type of valve has the drawback that the circulating fluid can be introduced into the cavity of the valve body, creating turbulences that increase pressure losses. Likewise, the fluid can accumulate in the aforementioned cavity making it difficult to accommodate the sealing element, also creating turbulences that in turn cause loss of pressure in the fluid flow. An example of such valves are those of the pivoting type that are used in gas installations or for fluids that circulate at low pressure.
    [0013]
    [0014] In these pivot valves, the plug element is eccentrically hinged and moves from an open position to a closed position, and vice versa, to allow or impede the passage of fluid flow through the valve. Said pivot valves have the aforementioned drawbacks, and also the disadvantage that the turning moment of an actuator element is high due to the friction that occurs between the sealing element and the inner surface of the valve body.
    [0015]
    [0016] Description of the Invention
    [0017]
    [0018] The objective of the present invention is to solve the aforementioned drawbacks by developing a pivot valve and a method to regulate the flow of a fluid by means of said valve that has the advantages described below.
    [0019]
    [0020] Preferably, the valve is suitable for a fluid in a liquid state, for example, water, oil, gasoline, diesel, kerosene, pentane, hexane, heptane, cyclohexane and methylcyclohexane. However, the fluid circulating inside said valve can also be a fluid in a gaseous state, for example, natural gas, methane, propane, butane, ethylene, propylene, butylene, butadiene and ethanol. In this way, the valve can be used in installations of both fluids in the liquid state and fluids in the gaseous state.
    [0021]
    [0022] In accordance with this objective, according to a first aspect, the present invention relates to a pivoting valve comprising a body including; an inlet port and an outlet port for the fluid flow passage, and a shutter element for the fluid flow passage pivotally mounted on a rotational axis of the valve body to be able to rotate from an open position to a position closing the fluid flow passage. Said valve is characterized by the fact that it comprises a tubular element to channel the fluid flow passage inside the valve body, said tubular element being interposed between said inlet port and said fluid flow outlet port, and mounted linearly displaceable so that it can be displaced from the outlet orifice to the inlet orifice when the shutter element is in an open position.
    [0023]
    [0024] The present invention has the advantage that it includes a tubular element that is movably mounted inside the body from the outlet hole to the input when the shutter element is not in a closed position. In this way it is possible to channel the fluid flow from the inlet port to the outlet port without creating excessive pressure drops during the passage of the fluid flow caused by the interference of a sealing element. Furthermore, the tubular element prevents the flow of fluid, which circulates through the valve, from entering the interior of the cavity where the sealing element is housed when it is in a usual opening position.
    [0025]
    [0026] In this way, a valve is obtained to regulate a fluid flow of reduced dimensions, compact and easy to use, in which high fluid pressure losses are reduced. In addition, the useful life of the valve is extended and the maintenance tasks to be carried out are also reduced.
    [0027]
    [0028] The valve object of the invention is especially suitable for fluids with a high viscosity, a characteristic that causes the fluid to undergo large pressure losses when it is circulated through installations in which, for example, it must be processed. Similarly, this valve is suitable for fluid installations with working pressure between pressures below atmospheric and 75000000 Pa. Surprisingly, this valve is also suitable for installations of fluids in a gaseous state, providing it with versatility to be used in any type of fluid installation.
    [0029]
    [0030] According to a preferred embodiment, the body includes a first body portion provided with a cavity defining an inlet port, a second body portion provided with a cavity defining an outlet port and a tubular member for channeling the assembled fluid flow linearly movable inside the body from a rest position in which it is housed in the cavity of the second body portion to a working position in which it contacts the first body portion when the sealing element is in a position of opening. In this way, the tubular element is located inside the body between the inlet hole and the outlet hole. In addition, the movement of the tubular element allows it to be placed in a position of rest separate from the sealing element, to facilitate movement from a closed position to an open position.
    [0031]
    [0032] Preferably, both the tubular element and the inlet and outlet ports have a circular section and aligned and aligned fluid passage dimensions. However, said section can be square, rectangular, triangular or any other geometric shape, always keeping the same fluid passage dimensions between said elements and always being aligned with each other.
    [0033] According to a preferred embodiment, the valve object of the invention comprises means for driving the movement of the tubular element inside the body, which comprise a mechanism provided with an actuator element, capable of being operated from outside the body, said mechanism including means to transmit the movement of the actuator element to the tubular element that is housed inside the body. In this way, the actuator element transmits the displacement to the tubular element so that it moves linearly inside the valve body until it is positioned in a position suitable to the demands of the installation. Said means for driving the displacement may, for example, be governed from a control box located outside the valve body.
    [0034]
    [0035] Advantageously, the actuator element is rotary and the transmission means include a gear associated with said actuator element and a rack attached to the tubular element and arranged in a groove provided on a surface of the tubular element, said tubular element being susceptible to being moved to the the gear is activated. In this way, the tubular element moves linearly when the movement of the actuator element is transformed into a linear movement by means of the gear associated with said actuator element and the rack attached to the tubular element. This type of mechanism allows the tubular element to be kept in the desired position, without the fluid flow path and the forces exerted by it displacing it.
    [0036]
    [0037] Optionally, the slot located in the tubular element has a groove or projection along said slot to ensure the linear movement of the tubular element inside the valve body. Similarly, said groove or projection can also be located on an opposite surface of the tubular element for greater efficiency in guiding the movement of said tubular element.
    [0038]
    [0039] According to a preferred embodiment, the tubular element is mounted movably from a rest position in which it is housed in the cavity of the second body portion to a working position in which it contacts the sealing element, when it is in a position closing. In this way, the contact of the sealing element with the first body portion is ensured, so that the fluid flow passage is effectively blocked. In addition, the force exerted on the plugged element by the pressure of the fluid flow is prevented from displacing it, causing the fluid to leak to the outlet port.
    [0040] Preferably, the valve object of the invention further comprises means for displacing the sealing element that include a mechanism provided with an actuator element capable of being actuated from outside the valve body, and means for transmitting the movement of the actuator element to the shaft of rotation of the shutter element. In this way, the movement, for example rotational, of the actuator element is transmitted to the axis of rotation of the shutter element to move it from a closed position to an open position, and vice versa. Said displacement means can, for example, be controlled from a control box located outside the valve body.
    [0041]
    [0042] Advantageously, the actuator element is rotary and the transmission means include a gear associated with said actuator element and a screw attached to the axis of rotation, said shutter element being able to move when said gear is actuated. In this way, the gear associated with the actuator element displaces the screw attached to the axis of rotation that transmits the movement to the shutter element to move it from an open position to a closed position depending on the needs of the installation. The displacement of the sealing element is both rotational and longitudinal.
    [0043]
    [0044] Optionally, the said means for displacing the sealing element include a spring at one end of the axis of rotation capable of being pressed against a surface of the first portion of the valve body, when said tubular element is located in a working position, being said same spring is capable of linearly displacing the sealing element on the axis of rotation when the blocking pressure of the tubular element ceases. In this way, said spring displaces the sealing element linearly, away from the surface of the inlet port, so that when turning said sealing element there is no friction between it and the surface of the first portion of the valve body. Similarly, the moment of rotation to be exerted by the axis of rotation of the sealing element must be less.
    [0045]
    [0046] According to a preferred embodiment, the first and / or second body portion is provided with a slot in an interior wall that defines a cavity to house an element that guarantees the sealing of the valve body. In this way, the flow of fluid circulating inside the valve is prevented from leaking to the outside, causing undesired situations for the correct operation of the installation or risk situations that may affect living beings or objects that found in the vicinity of said facility.
    [0047] Optionally, other components of the valve, such as, for example, the axis of rotation, the sealing element, the tubular element or the actuating element, may have anti-leakage elements to ensure that the fluid flow does not leak to the outside of the valve. valve, providing security against risky or unwanted situations in the installation. Said anti-leakage elements can be, for example, an O-ring, a graphite seal or a thermoplastic seal among others.
    [0048]
    [0049] Preferably, an outer wall of said first and / or second valve body portion defines an outer length of conduit to engage a flange. In this way, said flange can be used to more easily connect the valve to a pipe in the installation.
    [0050]
    [0051] Optionally, the outer wall of said first and / or second valve body portion may include a plurality of holes in its surface for attaching a flange by for example screws.
    [0052]
    [0053] As mentioned above, the pivot valve object of the invention may comprise a control box located on the outside to govern the means for displacing the sealing element and the means for driving the movement of the tubular element by means of an actuator element, depending on the needs of the installation. This control box may also receive external signals to govern said valve. Likewise, this valve will be provided with a safety system that will be activated if necessary, which will position the sealing element in a closed position and the tubular element in a working position in contact with said sealing element.
    [0054]
    [0055] According to the same objective, according to a second aspect, the present invention relates to a method for regulating the flow of a fluid, by means of the claimed valve comprising the steps of:
    [0056]
    [0057] a) moving a tubular element from a working position in which it contacts a sealing element when it is in a closed position, to a rest position in which it is housed in the cavity of the second portion of the valve body.
    [0058] b) moving a plug element from a closed position to an open position to allow the passage of fluid flow inside the valve from a inlet hole to outlet hole,
    [0059] c) moving a tubular element from a rest position in which it is housed in the cavity of the second portion of the valve body to a working position where it contacts the first portion of the valve body when the plug element is in an open position,
    [0060] d) maintaining the tubular element for a predetermined time allowing fluid flow to pass through the interior of the valve from the inlet port to the outlet port, and e) moving the tubular element from a working position in which it contacts the first body portion when the sealing element is in an open position, up to a rest position where it is housed in the cavity of the second body portion.
    [0061]
    [0062] According to the claimed procedure, after step e) a step f) of moving the plug element from an open position to a closed position is carried out to block the passage of fluid flow inside the valve from the inlet hole to the outlet hole. In this way, the movement of the sealing element interrupts the passage of fluid flow from the inlet hole to the outlet hole.
    [0063]
    [0064] Advantageously, after step f), a step g) is carried out to move the tubular element from a rest position to a working position in which it contacts the sealing element to ensure the blockage of the fluid flow passage from the inlet hole to the outlet hole. In this way, the tubular element presses the sealing element against a surface of the first body portion, specifically in the vicinity of the inlet port, to avoid its displacement due to the forces exerted by the pressure of said fluid flow and to ensure that it does not leak into the outlet hole. Also, in a preferred embodiment, the tubular element and a control box that governs the movements of the valve elements create a locking system that prevents the sealing element from moving, ensuring that the sealing element is kept in the closed position. and with the tubular element pressing it in case of malfunction or emergency.

    [0091] Description of a preferred embodiment
    [0092]
    [0093] A preferred embodiment of the pivot valve 1 is described below with reference to Figures 1 to 11.
    [0094]
    [0095] In said embodiment, the flow of fluid circulating through the valve is a hydrocarbon in a liquid state, specifically oil.
    [0096]
    [0097] The pivot valve 1 of the present invention comprises a body 2a, 2b, an inlet port 3 and an outlet port 4 for the fluid flow passage, a shutter element (5) of the pivot fluid flow passage mounted on a axis 6 of rotation of the body 2a, 2b of the valve 1, and a tubular element 7 to channel the passage of fluid flow inside the body 2a, 2b of the valve 1.
    [0098]
    [0099] The body 2a, 2b the valve is formed by two body portions 2a, 2b, a first body portion 2a having a cavity 8 defining an inlet port 3, and a second body portion 2b provided with a cavity 9 that defines an exit hole 4. The Inlet port 3 is provided for fluid flow to enter the valve interior and outlet port 4 for fluid flow to exit.
    [0100]
    [0101] Both portions 2a, 2b are joined together by a multitude of screws 19 arranged in through threaded holes 20 that cross the first portion 2a of the valve body and coincident with blind threaded holes 23 located in the second portion 2b of the body. valve.
    [0102]
    [0103] In the described embodiment, the second body portion 2b is provided with a groove 15 in a surface of an inner wall so as to define a cavity to house an element 16 that guarantees the tightness of the body 2a, 2b. Likewise, the first body portion 2a is provided on an inner wall with a projection 21 which coincides with the slot 15 provided on the inner wall of the second body portion 2b. In this way, the element 16 that guarantees the watertightness of the body 2a, 2b that remains a prisoner between the groove 15 and the projection 21, avoiding the leakage of the fluid outside the valve 1 in an efficient way.
    [0104]
    [0105] In figure 1 it is observed how the first and second body portions 2a, 2b form a cube-shaped valve 1 with rounded corners so that the interior of the body 2a, 2b is used to the maximum to accommodate all the elements, provided therefore a compact and small size valve 1.
    [0106]
    [0107] The valve 1 comprises inside the body 2a, 2b a shutter element 5 of the fluid flow passage that is mounted on a rotation axis 6, so that it pivots from an opening position in which the flow passage is allowed of fluid to a closed position where it prevents the passage of fluid flow. A control box (not shown) governs the movements of the shutter element 5 by means of movement means that have a rotation axis 6 mounted inside the body 2a, 2b and a rotary actuator element 12.
    [0108]
    [0109] The actuator element 12 has a gear 13a associated with a screw 13b located on the axis of rotation 6, so that it transmits the rotary movement to the shutter element 5 that is moved by rotation from an open position to a closed position, or vice versa. In the described embodiment, the actuator element 12 is located perpendicular to the axis of rotation 6, the gear 13a and the screw 13b forming an endless screw that transmits the rotary movement of the actuator element 12 to the shutter element 5.
    [0110] Furthermore, in this embodiment, the axis of rotation 6 includes at one of its ends a spring 14 that can be compressed by the sealing element 5 when the tubular element 7 is moved to a working position to contact the sealing element 5. In In this situation, the tubular element 7 presses the sealing element 5, so that the latter in turn compresses the spring 14. In the same way, when the tubular element 7 to channel the fluid flow stops exerting pressure on the sealing element 5 This moves linearly on the axis of rotation 6 away from an inner wall of the first portion 2a of the body.
    [0111]
    [0112] The body 2a, 2b also comprises inside it a tubular element 7 to channel the fluid flow mounted so that it can move linearly from a rest position in which it is housed in the cavity 9 of the second body portion 2b, until the inlet port 3 in a working position where it contacts the first body portion 2a. Similarly, the tubular element 7 for channeling the fluid flow can be moved from a rest position to a working position in which it contacts the shutter element arranged in a closed position to block the passage of fluid. A control box (not shown) governs the movements of the tubular element 7 by means of actuation means including a rotary actuator element 10, a gear 11a associated with said actuator element 10 and a rack 11b arranged in the tubular element 7.
    [0113]
    [0114] In the described embodiment, the rotary actuator element 10 is actuated from the outside of valve body 2a, 2b of valve 1. Furthermore, this element is associated with a gear 11a and rack 11b is arranged in a guide groove 18 provided on the surface of the tubular element 7 so that a portion of the length of said element extends. As the actuator element 10 rotates, the teeth of the gear 11a mesh with the teeth of the rack 11b, linearly displacing the tubular element to the desired position. These actuating means allow the tubular element 7 to be kept in the desired position, without the fluid flow passage and the forces exerted by it displacing it.
    [0115]
    [0116] Optionally, the groove 18 located in the tubular element 7, has a groove or projection along said groove 18 to ensure the linear movement of the tubular element 7 inside the body 2a, 2b of the valve 1. In the same way , said groove or projection can also be located on an opposite surface of the tubular element 7 for greater efficiency in guiding the movement of said tubular element 7.
    [0117] In the described embodiment, the outer wall of the first body portion 2a has an outer duct section 17 for coupling a flange (not shown) by, for example, welding. In an alternative embodiment not shown, said outer section 17 can be arranged on the outer wall of the second body portion 2b or in both body portions 2a, 2b to couple both flanges 2a, 2b to each flange (not shown).
    [0118]
    [0119] In figure 11 it is observed how the outer wall of the second body portion 2b is provided with holes 22 for coupling the valve 1 to a conduit (not shown) of an installation or to a flange (not shown). In an alternative embodiment not shown, said holes 22 can be arranged both on an outer wall of the first body portion 2a, and on an outer wall of the second body portion 2b, and on both walls of the first and second portion 2a paths. , 2b of valve body 1.
    [0120]
    [0121] The procedure for regulating the flow of a fluid by means of a valve 1 of the described embodiment is described below, according to Figures 1 to 11.
    [0122]
    [0123] In a first stage, the control box (not shown) sends a signal to drive the rotary actuator element 10 so that it rotates the gear 11a that is associated with the rack 11b arranged in the slot 18 of the surface of the tubular element 7 In this way, the teeth of the gear 11a contact the teeth of the rack 11b displacing the tubular element 7 for fluid flow channeling from a working position in which it presses the sealing element 5 when it is in a closed position to a position in which it is housed in the cavity 9 of the second portion (2b) of the valve body (1).
    [0124]
    [0125] At the same time, the spring 14 longitudinally displaces the sealing element 5 separating it from an inner surface of the first portion 2a of the valve body. In this way, the shutter element does not contact said inner surface, preventing friction from occurring between said shutter element 5 and said inner surface in subsequent stages.
    [0126]
    [0127] In a later stage, the control box (not shown) sends a signal to drive the rotary actuator element 12 so as to rotate the gear 13a that is associated with the screw 13b of the rotation shaft 6. In this way, the axis of rotation 6 on which the shutter element 5 is positioned, which is longitudinally and rotationally displaced from a closed position to an open position to allow the passage of fluid inside the valve 1.
    [0128]
    [0129] The control box (not shown) then sends a signal to drive the rotary actuator element 10 by displacing the tubular element 7 for fluid flow channeling from a rest position in which it is housed in the cavity 9 of the second portion 2b body to a working position where it contacts the first body portion 2a.
    [0130]
    [0131] The tubular element 7 for fluid flow channeling is kept in said position for a determined time to allow the passage of the fluid flow through it, from the inlet hole 3 to the outlet hole 4. When it is desired to interrupt the passage of fluid, the control box (not shown) sends a signal to drive the rotary actuator element 10 to linearly move said element 7 from a working position in which the tubular element 7 contacts the first body portion 2a to a position of resting in which it is lodged in the cavity 9 of the second portion 2b.
    [0132]
    [0133] Subsequently, in valve 1 a displacement of the shutter element 5 is carried out when the control box (not shown) sends a signal to the actuator element 10, which, in turn, transmits a rotary movement to the axis of rotation 6 on which the shutter element 5 is arranged so that it moves from an open position to a closed position to prevent fluid flow from circulating through valve 1.
    [0134]
    [0135] Finally, the tubular element 7 is linearly moved from a rest position to a working position in which it contacts the sealing element 5 by pressing it against a wall of the first body portion 2a and in turn pressing the spring 14.
    [0136]
    [0137] Although reference has been made to a specific embodiment of the invention, it is evident to a person skilled in the art that the machine and procedures described are susceptible to numerous variations and modifications, and that all the mentioned details can be replaced by others technically. equivalent, without departing from the scope of protection defined by the appended claims. For example, although it has been described that the fluid circulating inside the valve is a hydrocarbon, specifically oil, this could also be, for example, water, oil, gasoline, diesel, kerosene, pentane, hexane, heptane, cyclohexane , methylcyclohexane, natural gas, methane, propane, butane, ethylene, propylene, butylene, butadiene, and ethanol.
