Field of Invention
[001] This invention relates to mechanical couplings for joining pipe elements end to end, and in particular, for joining flanged pipe elements to non-flange pipe elements. Fundamentals of the Invention
[002] As taught in the prior art, connecting an unflange polymer tube element to a polymer or metal flanged tube element requires the use of a backing ring, usually made of metal, and a top flange adapter of polymer. To make the connection, the backing ring is slipped over the free end of the non-flanged polymer tube element and then the butt flange adapter is coaxially aligned with and fused to the free end of the non-flanged tube element in a gasket. top. This creates a flanged liner over the previously unflanged polymer tube element which is then engaged, flange-by-flange, with the flanged tube element. The backing ring is then placed to rest on the top flange adapter flange and dowels are used to attach the backing ring to the flange of the flanged pipe element, capturing and retaining the top flange adapter flange to the element. of flanged pipe. For polymer flange to metal engagement under low pressure applications the soft polymer flange of the top flange adapter deforms upon contact with the metal flange of the flanged pipe element to form a fluid tight seal. For higher pressure applications a face seal can be used between the interface flanges to ensure fluid tightness.
[003] Although effective, this prior technique practice suffers from several disadvantages. Multiple parts, namely the top flange adapter and backing ring, must be supplied and mounted on the unflange polymer tube element. A casting operation is required to join the top flange adapter to the unflange polymer tube. This requires a casting machine, which requires power or a heat source for operation. The casting operation itself takes time and is affected by the weather when joints must be made in the field. For example, cold weather will slow down the melting process, and can stop it altogether if severe enough. There is clearly a need for improved components and a method for joining non-flanged polymer tube elements to flanged tube elements. Invention Summary
[004] The invention relates to a coupling for joining a flanged pipe element to a single-ended pipe element. In an exemplary embodiment the coupling comprises a plurality of segments affixed to one another in an end-to-end spaced relationship surrounding a central space. By way of example, each of the segments comprises oppositely arranged first and second sides. A first channel is positioned close to the first side and extends circumferentially around and facing the central space. A first flange is positioned near the second side and extends outwardly away from the center space. The first flange has a plurality of holes therethrough. A second channel is positioned between the first channel and the flange and extends circumferentially around and faces the central space. The coupling further comprises a split ring positioned in the first channel. A seal is placed in the second channel. A tube is positioned within the central space and extends outward from the second sides of the segments. The tube engages the seal. A second flange may extend outward from the pipe and positioned adjacent to the first flange. A burr may extend outward from the pipe near one end of the pipe.
[005] In an exemplary embodiment, the first channel comprises two side surfaces arranged in spaced relationship. At least one of the segments may have at least one notch positioned on the two side surfaces adjacent an end of the at least one segment. A floor surface extends between the side surfaces. The lateral surface comprises first and second surface portions respectively arranged at opposite ends of the segments. A third surface portion is positioned between the first and second surface portions. The first and second surface portions each have a radius of curvature greater than a radius of curvature of the third surface portion. In a specific exemplary embodiment the radius of curvature of the first and second surface portions in at least one of the segments is equal to an outer radius of curvature of the split ring. By way of further example, at least one of the first and second surface portions has a length extending from 5% to 45% of the total circumferential length of the first channel.
[006] In an exemplary embodiment the seal comprises a flexible resilient sealing ring having first and second inner ring surfaces adapted to respectively engage outer surfaces of the tube and the tube element. One of the inner ring surfaces has a diameter sized to receive the tube element by inserting the tube elements between the segments. By way of further example, the seal has an outer surface engaged with and supporting the segments in a pre-assembled state in sufficient spaced apart relationship to allow the tube element to be inserted into the central space. In an exemplary embodiment, the split ring has an outer radius of curvature and an inner radius of curvature. The inner radius of curvature is equal to or greater than the outer radius of the tube element.
[007] In an exemplary embodiment, the split ring supports the segments in a pre-assembled state in a relationship spaced apart from each other sufficient to allow the tube elements to be inserted into the central space. As a further example, the split ring has sufficient rigidity to maintain the segments in the pre-assembled state by handling the coupling during insertion of the tube element. By way of further example, the split ring comprises a plurality of teeth arranged in spaced relation to one another and extending circumferentially around the split ring, the teeth projecting towards the central space.
[008] In an exemplary embodiment the segments comprise adjustablely squeezable display members to drive the segments towards the central space. In a specific example, the adjustably fastenable display members comprise projections extending from opposite ends of each segment. Each projection defines an opening to receive a fastener. Fasteners extend between the segments and hold the segments together in a pre-assembled state. Brief Description of Drawings

Detailed Description of the Invention
[0010] Figure 1 shows an exemplary embodiment of a coupling 10 for joining flanged pipe elements to non-flange pipe elements according to the invention. Coupling 10 comprises a plurality of segments, in this example two segments 12 and 14 affixed to each other end to end and surrounding a central space 16. Segments 12 and 14 are advantageously formed of ductile cast iron, although other materials may also be used. Attachment of segments 12 and 14 is accomplished by means of adjustable attachment members 18 positioned at each end of each segment. In that example display members 18 comprise projections 20 extending from the ends of the segments, the projections having openings 22 that receive a fastener such as bolt 24 and nut 26. Upon tightening of the fasteners 24, 26 the segments 12 and 14 are led towards each other and the central space 16 to perform connection with a tube element 28 as shown in figures 4 and 5 and described below.
[0011] As shown in Figure 2, coupling 10 has first and second sides 30 and 32 disposed opposite each other. A first channel 34 is positioned in segments 12 and 14 near the first side 30. First channels 34 extend circumferentially around and face the central space 16. First channels 34 are each defined by two arranged side surfaces 36 and 38 in a spaced relationship to each other. A tread surface 40 extends between the side surfaces. As shown in Figure 3, side surface 40 comprises first and second surface portions 42 and 44 respectively arranged at opposite ends 46 and 48 of segments 12 and 14 (segment 12 being shown). A third surface portion 50 is positioned between the first and second surface portions 42 and 44. Each surface portion 42, 44 and 50 has a respective radius of curvature 42a, 44a and 50a. Rays 42a and 44a are greater than the radius of curvature 50a of the third surface portion 50. The centers of the spokes 42a and 44a are offset from the center of the radius 50a as shown in Figure 3. The first and second surface portions 42 and 44 may each have a length extending from about 5% to about 45% of the total length of the first channel 34 for practical coupling designs.
[0012] As shown in figures 1 and 2, the coupling 10 further comprises a first flange 52 positioned near the second sides 32 of each segment 12 and 14. Flange 52 is formed by flange portions 52a and 52b in respective segments 12 and 14 and extends outwardly away from the central space 16. Flange 52 has a plurality of through holes 54 (see also Figure 1A). Flange 52 and through holes 54 are designed to mate with the flange of a flanged end pipe element as described below. A second channel 56 is positioned in each segment 12, 14 between the first channels 34 and the first flanges 52. Second channels 56 extend circumferentially around and face the central space 16. Similar to the first channels 34, second channels 56 are each defined by two side surfaces 57 and 59 arranged in spaced relationship to one another as shown in Figure 2. A tread surface 61 extends between the side surfaces. As shown in Figure 3A, side surface 61 comprises first and second surface portions 63 and 65 respectively arranged at opposite ends 46 and 48 of segments 12 and 14 (segment 12 being shown). A third surface portion 67 is positioned between the first and second surface portions 63 and 65. Each surface portion 63, 65 and 67 has a respective radius of curvature 63a, 65a and 67a. Rays 63a and 65a are greater than the radius of curvature 67a of the third surface portion 67. The centers of rays 63a and 65a are offset from the center of radius 67a as shown in Figure 3A. The first and second surface portions 63 and 65 can each have a length extending from about 5% to about 45% of the total length of the second channel 56 for practical coupling designs.
[0013] As shown in Figures 1 and 2, a slotted ring 58 is positioned within the first channels 34 of segments 12 and 14. The slotted ring 58 in this example comprises a plurality of teeth 60 arranged in spaced relationship to each other. Teeth 60 extend circumferentially around slotted ring 58 and project towards central space 16. Such slotted rings are made of metal, such as spring steel, stainless steel or beryllium copper alloys and are effective in retaining elements of tube made of HDPE or other polymer resins, to coupling 10. Split ring 58 has an inner diameter 62 equal to or greater than the outer diameter of the tube element. Teeth 60 may additionally be angularly oriented to enable insertion of the tube element into central space 16, but prevent its withdrawal.
[0014] Slotted ring 58 can be used to hold segments 12 and 14 in spaced apart relationship in the so-called "pre-assembled state" illustrated in Figure 1A. Split ring 58 has an outer diameter 64 sized to engage the first and second surface portions 42 and 44 of tread surface 40 (see Figure 3). These surface portions have radii of curvature 42a and 44a greater than the third surface portion 50 and are designed to cooperate with slotted ring 58 to support segments 12 and 14 so that tube element 28 can be inserted into the central space. 16 from side 30 when coupling 10 is in the pre-assembled state. Fasteners (bolts 24 and nuts 26) hold segments 12 and 14 together and against split ring 58, which has sufficient stiffness to support the segments during handling for installation but, being a split ring, it is retractable to a smaller diameter and allows that the segments are driven towards each other and make a mechanically constrained fluid-tight joint when the fasteners are tightened as described below.
[0015] The fluid tightness of the gasket is provided by a seal 66 positioned in the second channels 56 of segments 12 and 14 as shown in Figure 2. This exemplary seal 66 comprises a flexible resilient seal ring 68. The seal ring 68 has a outer surface 70 having a diameter 71. In an exemplary embodiment, diameter 71 is sized to support segments 12 and 14 in spaced relationship in the pre-assembled state, or to assist split ring 58 in supporting the segments. For this purpose the outer diameter 71 is dimensioned to engage the first and second surface portions 63 and 65 of tread surface 61 of the second channel 56 (see Figure 3A). These surface portions have radii of curvature 63a and 65a greater than the third surface portion 67 and are designed to cooperate with the sealing ring 68 to support the segments 12 and 14 to enable insertion of the tube element 28 into the central space 16a starting from side 30 when coupling 10 is in the pre-assembled state shown in figure 1A. Gasket 68 may also have sufficient rigidity to support the segments during handling for installation. Gasket 68 can be formed from elastomers such as EPDM and is therefore deformable upon tightening fasteners 24, 26 to enable a gasket to be formed as described below.
[0016] To perform a fluid-tight seal, seal ring 68 has first and second inner ring surfaces 72 and 74 positioned on opposite sides of the seal ring. Surface 72 is positioned and adapted to engage tube element outer surface 28 upon insertion of tube element into central space 16 (described below). As shown in Figure 2, surface 74 is adapted to engage the outer surface of a tube 76 positioned within the central space 16. A burr 77 is positioned proximate a tube end 76 to engage the lobe 74a on which inner surface 74 is positioned. . Burr 77 extends circumferentially around and outward from tube 76 and helps retain the tube within gasket 68. Tube 76 is part of coupling 10 and extends outward from second sides 32 of segments 12 and 14. A second flange 78 may extend outwardly from the tube 76 and is positioned in spaced relationship away from the burr 77, adjacent to the first flange 52 when the opposite end of the tube 76 is engaged by the inner surface 74 of the gasket. 68 as illustrated in Figure 2. It is advantageous to form tube 76 and its flange 78 as a unitary piece from a polymer resin such as HDPE. This design helps ensure fluid tightness of the joint as noted below. O-ring 68 may also have an inwardly projecting rib 80 that engages both the tube 76 and the tube member 28 and acts as a stop to ensure adequate depth of engagement between these components and the coupling 10.
[0017] Installation of coupling 10 is illustrated with reference to figures 1A, 4, 5 and 6. Pipe element 28 must be connected to a flanged pipe element 82 (see figure 5). As shown in Figures 1A and 6, the tube element 28 is inserted into the central space 16 of coupling 10 from the first side 30 of segments 12 and 14. Insertion is possible because coupling 10 is in the pre-assembled state, with segments 12 and 14 supported in spaced relationship on seal 66 only, split ring 58 only, or both the seal and split ring. Insertion is additionally aided by notches 94 positioned in side surfaces 36, 38 of each segment 12 and 14. Notches 94 are positioned adjacent to posting members 18 (projections 20) and provide clearance for tube element insertion that enables the segments 12 and 14 are closer together in the pre-assembled state than would be possible in the absence of the notches. Once tube member 28 is properly seated (end engaging stop groove 80, sealing ring inner surface 72 engaging outer surface of tube member) fasteners 24, 26 are thereby tightened leading segments 12 and 14 towards one another. to the others as shown in figures 4 and 5. Movement of segments 12 and 14 deforms both split ring 58 and seal 66.
[0018] Slotted ring 58 contracts in circumference and diameter when it is forced to conform within the first channel 34. Contraction of the slotted ring 58 causes teeth 60 in the slotted ring to bite into the outer surface of the tube element 28 and prevent its withdrawn from coupling 10. Seal 66, clamped within second channel 56, is compressed between segments 12 and 14 as the segments are placed together. As shown in Figure 5, the inner surface sealing ring 72 is forced into sealing engagement with the outer surface 84 of the tube element 28, and the inner surface sealing ring 74 is placed in sealing engagement with the outer surface 86 of the tube. 76.
[0019] With segments 12 and 14 placed together as shown in figures 4 and 5, the first flange 52 is therefore arranged so that its holes 54 can be aligned with corresponding holes 88 in the flange 90 of the flanged tube element 82 to the which tube element 28 is to be joined. As shown in Figure 5, coupling 10 is aligned with flanged tube element 82, holes 54 in first flange 52 are aligned with holes 88 in flange 90 and fasteners 92 are received in holes 54 and 88 to connect first flange 52 to flange 90 of flanged pipe element 82. Second flange 78 of pipe 76 is captured between flange 90 and first flange 52. This configuration provides rigidity and stability to the joint as well as fluid tightness between coupling 10 and flanged pipe element 82 as the softer polymeric material comprising second flange 78 is compressed between metal flanges 90 and 52, which may comprise cast iron, steel or other durable metals.
[0020] Couplings according to the invention provide advantages over prior art methods and couplings for joining non-flange polymeric pipe elements to flanged pipe elements. Being in a pre-assembled state, couplings according to the invention reduce the number of parts that must be handled during installation. Additionally, the step of casting a top flange adapter to the unflange polymer tube element is eliminated along with the need for a casting machine. Installation time and complexity and complexity are thereby substantially reduced.
