    MOBILE SHUTTER FOR FLUID CHANNEL
    Description
    Technical Field of the Invention The invention relates to a movable shutter for fluid channeling.
    It concerns the technical field of equipment for various piping systems, in particular hydrocarbon refining, gas treatment or petrochemical installations. State of the art To date, many sliding shutters allow to equip the fluid conduits so as to move from an open position to a closed position, or vice versa. Document FR 2733024 (MECHANICAL AND TECHNICAL COMMERCIAL) proposes, for example, the sliding shutter shown in Figures 1,2,3, 4a and 4b. It consists of: two half-bodies 2, 3 associated with a locking mechanism to bring them closer or away from one another. Each of the half-bodies 2, 3 comprises a tube 21, 31 forming a channel and allowing the passage of the fluid. Each of the ends of the tube 21, 31 is respectively fixed to a flange 22, 32 and a plate 23, 33. Each plate 23, 33 has a rear face connected to the tube 21, 31, and a bearing face 231, 331, a flat lid 1, shown in greater detail in FIG. 5, mounted movably between the bearing faces 231, 331 of the plates 23, 33. The lid 1 consists of a body 11 divided into two symmetrical parts with respect to each other. the transverse median plane 14. The body 11 has two longitudinal plane faces 111, 112 parallel to each other. The first part 12 is a solid part which, in a closed position (FIG. 4a), closes the pipe so as to prevent fluid flow between the two half-bodies 2, 3. Arrangements 121 are provided on each of the longitudinal faces. 111, 112, which arrangement are adapted to align with the tubes 21, 31 when the shutter 1 is in the closed position. The second part 13 is a part pierced by an opening 131 opening at each of the longitudinal faces 11, 112. In the open position (Figure 4b), the pierced portion (13) is placed in the center of the pipe, aligned with the tubes 21, 31, so as to allow a fluid flow between the two half-bodies (2, 3).
    The locking mechanism is composed of four yokes 6a, 6b, 6c, 6d, parallel to the axis of the half-bodies 2, 3, and articulating on the latter by means of: two motor shafts 4a, 4b fixed on a first half-body 2, two fixed receiving shafts 5a, 5b fixed on the second half-body 3.
    The rotation of the motor shafts 4a, 4b causes the half-bodies 2, 3 to move towards one another. The two motor shafts 4a, 4b are simultaneously rotated by means of two cranks secured to one end of each of the trees 4a, 4b. The cranks are interconnected by a rod 7. A lever 8, secured to one of the cranks, makes it possible to perform the rotational movement.
    The locking mechanism is adapted to be able to pass the half-bodies 2, 3 from a position apart to a close position. In FIGS. 1 and 3, the locking mechanism holds the trays 23, 33 in a spaced apart position where the bearing face 231, 331 of said trays is spaced from the respective longitudinal face 111, 112 of the lid 1. allows the displacement of the lid 1 between the closed and open positions.
    After actuation of the locking mechanism, the half-bodies 2, 3 are found in the close position shown schematically in Figures 2, 4a and 4b. In this close position, the bearing faces 231, 331 seal the body 11 to block the lid 1 in the open or closed position. The bearing faces 231, 331 each come into close contact with the respective longitudinal face 111, 112 of the lid 1. FIG. 4a shows schematically the case where the lid 1 is in the closed position, while FIG. 4b represents the case where the cover 1 is in the open position. The shutter proposed in the patent FR 2733024 (COMMERCIAL MECHANICAL AND TECHNICAL) also has seals 9 disposed on both longitudinal faces 111, 112 of the seal 1. These seals 9 are placed around the opening 131 and around the arrangements 121. The movable shutter described above has the disadvantage of not presenting any method to verify the proper positioning of the lid between the two trays. Indeed, a bad positioning can have serious consequences on the installation, causing leaks of fluid and endangering the operators.
    WO 92/14957 (ONIS) discloses a movable shutter to avoid some of the aforementioned drawbacks. It proposes a system for securing the positioning of the lid. This system consists of a locking pin which can be inserted into two holes made in the lateral faces of the body of the lid, the position of these holes respectively corresponding to the open position and the closed position of the lid. 'shutter. This safety system prevents the lid from being moved as long as the half-bodies are not completely loosened in the separated position.
    However, such a system is complicated to implement since the holes in the lid must be made in specific positions. In addition, the installation and use of the locking finger are complex, the operator must correctly introduce it into the right hole. The invention aims to remedy this state of affairs. In particular, an object of the invention is to provide a movable shutter making it easy to ensure that the cover is correctly positioned.
    Another object of the invention is to provide a movable shutter whose manufacture and installation are simplified, thus limiting production costs.
    Yet another object of the invention is to provide a movable shutter for moving easily from a closed position to an open position, or vice versa.
    Disclosure of the invention.
    The solution proposed by the invention is a movable shutter for fluid channeling comprising: two half-bodies arranged so as to form a fluid channel, said half-bodies being each formed of a pipe forming tube and at the ends of which are respectively fixed a flange and a plate, each of said plates having a bearing surface, - a seal in the form of a body delimited by two opposite planar longitudinal faces each disposed respectively vis-à-vis the face d platen support, which cap has a solid portion and a portion pierced by an opening opening at each of said longitudinal faces, which cap is movably mounted between the bearing faces between: a closed position where the solid part closes the pipe so as to prohibit a fluid flow between the two half-bodies, o an open position where the part pe rcée is placed in the center of the pipeline so as to allow a fluid flow between the two half-bodies, - a locking mechanism adapted to maintain the trays in: o a spaced apart position where the bearing surface of the trays is spaced from the respective longitudinal face of the cap so as to allow the displacement of said cap between the closed and open positions, o a close position where the bearing faces tightly grip the body of the cap to block said seal in opening or closing position, said bearing faces each coming into close contact with the respective longitudinal face of the lid,
    This invention is remarkable in that at least one projecting element is arranged on the bearing surface of at least one plate or on at least one of the longitudinal faces of the body of the lid, which projecting element is arranged with so that if the cap is not correctly positioned in the closed position or in the open position, said projecting element forms an obstacle which keeps the bearing face at least one plate and the longitudinal face respective, so that the locking mechanism can not maintain the trays in the close position.
    Such a device allows the operator to ensure that the lid is in the desired position. Indeed, whether in the open or closed position, a good alignment of the lid with the tubes of the half-bodies, is necessary to avoid any leakage of fluid. Thanks to the invention, the operator can no longer fully maneuver the locking mechanism until the cap is correctly positioned. Other advantageous features of the invention are listed below.

    Preferred embodiments of the invention The mobile shutter object of the invention is similar to that already present in the state of the art and described above with reference to Figures 1, 2, 3, 4a and 4b. The invention lies in the shape in which the lid 1, or the bearing face 231, 331 of the plates 23, 33, is formed, this shape making it possible to ensure that it is correctly positioned by preventing the mechanism of locking to maintain the half-body 2, 3 in the close position, and thus avoid any risk of leakage of fluid.
    During the installation of the shutter, the flanges 22, 32 of each of the half-bodies 2, 3 are connected to the fluid pipe so that it aligns with the tubes 21, 31. The flanges 22, 32 are then secured to the pipe by means of fixing means such as bolts, welds, or screws. In the spaced apart position, each of the bearing faces 231, 331 of the plates 23, 33 is vis-à-vis the respective longitudinal face 111, 112 of the lid 1, when it is slid into the spacing between the two half-bodies 2, 3.
    A lid 1 according to the invention is shown in Figures 6a, 6b and 6c. It comprises a body 11 which is preferably in the form of a rectangular parallelepiped, but may be in other forms such as a cube, or any other parallelepiped. It is made of a rigid and waterproof material such as aluminum, stainless steel, or a plastic. The body 11 of the lid has a width that can be between 4 cm and 65 cm, a length varying between 15 cm and 300 cm, and a thickness that can range from 1 cm to 15 cm. The cover 1 is divided into two parts 12, 13 symmetrical with respect to the transverse median plane 14 and aligned with respect to each other on the sagittal plane S of the body 11. The first part 12, also called the solid part, presents a layout 121 of circular shape, which is found preferentially on both longitudinal faces 111, 112. This arrangement 121 is surrounded by a circular groove 122. The latter has a depth ranging from 0.3 cm to 2 cm and a width that can vary for example, from 0.3 cm to 2 cm. The dimensions of the arrangement 121 correspond to the section of the tubes 21, 31. The diameter of the arrangement 121 is, for example, between 2 cm and 40 cm.
    The second part 13, also called the pierced portion, has an opening 131 having a shape equivalent to that of the arrangement 121. The opening 131 is surrounded by a circular groove 132 having the same dimensions as the groove 122.
    Annular seals 123 and 133 are introduced respectively into the grooves 122 and 132. These seals 123, 133 may have a circular section, but may also have a rectangular or triangular section. They are preferably made of a flexible material such as rubber, fluororubber or polyethylene but may also be made of graphite, silicone or polyurethane. Preferably, they have a thickness substantially greater than the depth of the grooves 122, 132, so as to exceed and allow to obtain a better seal when the bearing faces 231, 331 of the plates 23, 33 come into contact with the longitudinal faces. 111, 112 respectively of the cover 1 when said trays are in the close position. This thickness is, for example, between 3 mm and 25 mm.
    In the embodiment shown in FIG. 6b, the cover 1 also has other grooves 16 concentric with the circular grooves 122, 132. These grooves 16 are circular and have a diameter substantially greater than that of the grooves 122, 132. diameter is between 8 cm and 110 cm. These grooves 16 are preferably made on the two longitudinal faces 111, 112 of the cover 1, but may be present on only one of said faces. These grooves 16 allow to install, temporarily or permanently, ring seals 9 adapted to make the system fireproof. These seals 9 are made of a non-flammable material, such as graphite.
    All grooves 122, 132, 16 are formed of a bottom and an opening, connected by side walls. They may, for example, have a section U or C, the bottom and the opening having the same dimensions. They may, however, have a shape in which the opening is narrower than the bottom, so that once inserted in force, their seal can not come out accidentally. The cover 1 is equipped with a positioning safety device which consists of at least one projecting element 15a, 15b arranged on at least one of the longitudinal faces 111, 112 of the body 11 of the cover 1 or on the bearing face (231, 331) of at least one plate (23, 33). Several embodiments of the positioning security device will now be described in detail.
    First embodiment (FIGS. 6a-6b, 7a-7d, 8, 9a-9b and 10)
    In this embodiment, the projecting element 15a is arranged on at least one of the longitudinal faces 111, 112 of the body 11 of the cover 1. A protruding element 15a may however be arranged on each of the two longitudinal faces 111, 112. The projecting element 15a is located between the solid part 12 and the pierced part 13. It is advantageously placed in the middle of the body 11, symmetrically with respect to the transverse median plane 14 and / or with respect to the longitudinal median plane S, and may to present oneself in various forms. Figures 7a to 7d show different examples of projecting elements 15a. This can be in the form of an hourglass (Figure 7a). In this configuration, the element 15a has two straight sides 151a, 152a parallel to the sagittal plane S (or longitudinal median plane) of the body 11. These right sides 151a, 152a are connected by curved sides 153a, 154a. These follow, for example, the shape of the solid parts 12 and pierced 13, or the shape of the trays 23, 33, which facilitates the correct positioning of the lid. The projecting element 15a can also be in different forms. It may, for example, be in the form of a transverse rib (FIGS. 7b and 7d) extending in all or part of the width of the body 11. This rib may be in various forms, for example a rectangular parallelepiped or a cube. It may have a length less than the width of the body 11 (Figure 7d) or have a length equal to the width of the body 11. In the preferred embodiment shown in Figure 7b, the length of the rib substantially corresponds to the body width 11. "Substantially" means that the length of the rib may be a few millimeters smaller than the width of the body 11.
    In FIG. 7c, the projecting element 15a is in the form of several transversely aligned ribs relative to each other, in the width of the body 11. FIG. 7c shows three ribs, but the lid 1 may comprise a different number, which can vary from 2 to 15. These ribs are aligned transversely and arranged in the middle of the body 11. The thickness of the projecting element 15a varies from 0.5 mm to 20 mm, preferably from 0.5 mm to 5 mm, its length is between 2 cm and 65 cm, and its width can vary from 0.5 cm to 10 cm. The protruding member 15a and the body 11 may be in the form of a one-piece piece, for example using a molding, stamping, or machining process. It can also be reported later on the body 11, by means of fixing means such as glue, welds, or screws. This two-part solution allows the use of different materials for the body 11 and for the projecting element 15a. The latter may for example be made of a more rigid material than that used for the body 11.
    Preferably, the projecting element 15a is symmetrical with respect to the transverse median plane 14 so that it is equidistant from the solid portion 12 and the pierced portion 13. It may, however, be positioned differently depending on the operator's needs.
    Figure 8 illustrates the shutter in the spaced apart position, the two half-bodies 2, 3 being spaced from each other. In this remote position, the cover 1 is free to move in the space between the two plates 23, 33, from the open position to the closed position or vice versa. In this spaced apart position, the spacing between the two support faxes 231, 331 of the plates 23, 33 is greater than the combined thickness of the body 11 and the projecting element 15a, which allows the displacement of the opercule 1. The bearing face 231, 331 of each of the plates 23, 33 is opposite the respective longitudinal face 111, 112 of the lid 1.
    FIGS. 9a and 9b illustrate the shutter with the plates 23, 33 in the close position, after the cover 1 has been positioned in the closed position ("blocking the fluid"; FIG. 9b) or in the open position ("Fluid passage", Figure 9a).
    In FIG. 9a, the shutter 1 is in the open position, the bearing faces 231, 331 of the plates 23, 33 respectively come into contact with each of the longitudinal faces 111, 112 of the cover 1 so that that the opening 131 is coaxial with the tubes 21, 31, in the center of the pipe. This configuration allows a tight connection of the fluid line between the two half-bodies 2, 3.
    In FIG. 9b, the shutter 1 is in the closed position, the arrangement 121 being coaxial with the tubes 21, 31. The bearing faces 231, 331 respectively come into contact with the longitudinal faces 111, 112 of the body 11 to block it in position. This configuration prevents any fluid communication between the two half-bodies 2, 3.
    The locking mechanism is used in order to bring the trays 23, 33 together and to block the cover 1 in position between the two support faces 231, 331. FIGS. 9a and 9b show the case where the cover 1 has been correctly positioned. , the opening 131 and the arrangement 121 being respectively coaxial with the tubes 21, 31. Only when the cover 1 is correctly positioned, the locking mechanism is locked and can maintain the half-bodies 2, 3 in close position.
    The locking mechanism, known from the state of the art, may for example be in the form of a latch 17 (shown in Figures 1 and 2). It may also be in the form of a system blocking the lever 8 after having the latter perform the rotational movement to bring the half-bodies 2, 3 together. In this configuration, the spacing between the two bearing faces 231, 331 corresponds to the thickness of the body 11, but remains less than the combined thickness of said body and the protruding element 15a. Thus, when the shutter is in the close position and the cover is positioned correctly, the projecting element 15a is outside the spacing between two bearing faces 231,331.
    Figure 10 shows the case where the cover 1 is incorrectly positioned. Indeed, the projection member 15a is in the spacing between two bearing faces 231, 331 and prevents the plates 23, 33 to reach their close position. Thus, the lid 1 is not sandwiched between the bearing faces 231, 331, the spacing between said bearing faces being greater than the thickness of the body 11. The locking mechanism can not then be locked and maintain the plates 23, 33 in the close position. The operator can not close the shutter until the cover 1 is moved until the protruding member 15a is outside the spacing between the bearing faces 231 , 331. The use of the shutter is not possible until the cover 1 is in the desired position, thus preventing any leakage.
    Second embodiment (FIGS. 6c, 11, 12a, 12b and 13)
    In this embodiment, the projecting element 15b is arranged on the bearing face 231, 331 of at least one of the plates 23, 33. A projecting element 15b may, however, be arranged on each of the two faces. support 231,331.
    This projecting element 15b cooperates with a housing 15c arranged on the respective longitudinal face of the body 11 (Figure 6c).
    In the embodiment illustrated in FIGS. 11, 12a, 12b and 13, the projecting element 15b is positioned on the bearing face 331 of the plate 33. The housing 15c is arranged on the longitudinal face 111 which is in the form of a screw. the front of the bearing surface 331. It is easily understood that the projecting element 15b can be positioned on the bearing face 231 of the plate 23, the housing 15c then being on the corresponding longitudinal face 112. Projecting elements 15b can also be arranged on each of two bearing faces 231, 313, corresponding housings 15c therefore being located on each of the longitudinal faces 111, 112 of the cover 1. The projecting element 15b is similar to FIG. element 15a described above with reference to the first embodiment, and may have the same shapes and dimensions as those illustrated in Figures 7a to 7d.
    Similarly, in the same way as described above, the projecting element 15b and the plate 33 on the bearing face 331 of which it is arranged, may be in the form of a single piece. The projecting element 15b may instead be attached to the bearing face 331, which projecting element is then held in position on said bearing face by means of fixing means of the type described above.
    The housing 15c has dimensions equivalent to those of the projecting element 15b so that it can fit into said housing 15c. The dimensions of the housing 15c, however, are preferentially greater than those of the projecting element 15b so as to facilitate the insertion thereof. The shape of the housing 15c is therefore complementary to that of the projecting element 15b.
    The housing 15c is formed in the body 11 of the lid 1, forming a part of lesser thickness. It is preferably carried out during the manufacture of the lid 1, for example during a molding process. However, it can be performed later using, for example, a method of machining, stamping or stamping.
    In FIG. 6c, the housing 15c is placed in the middle of the body 11, preferably along the transverse median plane 14. It may be symmetrical with respect to the transverse median plane 14 so as to be equidistant from the solid portion 12 and the pierced portion 13. It is also symmetrical with respect to the longitudinal median plane S. The housing 15c can however be positioned differently depending on the needs of the operator.
    In FIG. 11, the plates 23, 33 are in the separated position. The spacing between the bearing faces 231, 331 is such that the cover 1 can be moved from the open position to the closed position, or vice versa. In this spaced apart position, the spacing between the two bearing faces 231, 311 is greater than the combined thickness of the projecting element 15b and the body 11. The term "body thickness" 11 is understood to mean the thickness of the part of the body 11 not having the housing 15c.
    Figures 12a and 12b describe the shutter with the plates 23, 33 in the close position. In Figure 12a, the shutter 1 is in the open position while in Figure 12b, it is in the closed position. The bearing faces 231, 331 come into contact with the longitudinal faces 111, 112 of the cover 1 so as to hold the latter in position.
    In the case where the cover 1 is correctly positioned (Figures 12a and 12b), the projecting element 15b and the housing 15c are centered so that said projecting element can be inserted into said housing 15c. The plates 23, 33 can then be moved to reach the close position, where they enclose the body 11 of the lid 1. In this configuration where the projecting element 15b disappears in the housing 15c, the spacing between the bearing faces 231, 331 corresponds to the thickness of the body 11. The locking mechanism can then be properly locked and maintain the half-bodies 2, 3 in this close position.
    Figure 13 shows the case where the cover 1 is incorrectly positioned. The projecting element 15b is eccentric housing 15c and abuts against the longitudinal face 111, forming an obstacle. The spacing between the two bearing faces 231, 331 is in this case greater than the thickness of the body 11, the latter being, therefore, not sandwiched between said bearing faces. The locking mechanism can not then be properly locked and keep the half-bodies 2, 3 in this close position, preventing the operator from closing the shutter. The arrangement of the various elements and / or means and / or steps of the invention, in the embodiments described above, should not be understood as requiring such an arrangement in all implementations. In any case, it will be understood that various modifications may be made to these elements and / or means and / or steps, without departing from the spirit and scope of the invention. In particular: the location 121 can be present on a single face 111, 112 of the cover 1.
