沿著管件周圍以螺栓連結。一般係使用兩片如此的半圓形 連結弧片。但較大尺寸的管件可能使用3片或更多之連結 弧片。 連結弧片末端包括有用於將連續的連結喊片連接在一 起的螺栓接納開孔。連結弧片通常具有一個鍵，該鍵於管 件周圍之凹槽內延伸。常發生情形是原本呈圓形之管件稍 微變形，而使連續的連結弧片之螺栓接納開孔不會對齊。 因此常需施以相當大的外力適當地使連結弧片儘可能靠近 地在一起，以妥善地銜接管件周圍。

如果凸緣弧片實際上並沒有下降至與管件凹槽之底牆 完全契合，則互相連接之強度將受到材料性貧的影響，管 件與配件之間藉以凸緣弧片的剛性連結可能無法達成。在 這樣一個情況下，連結器所能承受之壓力也會降低。 史密斯（Smith)的美國專利案第696,603號中係揭示 一種具有二對互相崁合之突起部與凹部的管件連結器。其 中一對是供作凸緣弧片初步組合時兩相鄰凸緣弧片之初步

Description of the invention (/) [Field of the invention] (Please read the precautions on the back before writing this page) This application is about an arc flange connector. A grooved pipe can be directly connected to a fitting with a flange connection, wherein the groove is formed around the outside of a free end adjacent to the pipe. [Background of the present invention] It is known that the arc flange connector is formed by a plurality of generally arched connecting arcs, and the connecting arcs are bolted along the circumference of the pipe in an end-to-end manner. link. Generally, two such semi-circular connecting arcs are used. However, larger size fittings may use 3 or more connecting arcs. The end of the connecting arc includes a bolt receiving opening for connecting successive connecting shouts together. The connecting arc usually has a key that extends into a groove around the tube. It often happens that the originally round pipe is slightly deformed, so that the bolt receiving openings of continuous connecting arcs will not be aligned. Therefore, it is often necessary to apply a considerable external force to properly bring the connecting arcs as close together as possible to properly join the surroundings of the pipe fittings. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economics. Typically, the previous structure of this type of 741-type arc connector (available from Victaiilic, USA) includes a radially extending ear at the end of the connecting arc that is bolted. Sheet. They must use tools (such as a pair of pliers or slot locks) to join them together so that the bolts can pass through the overlapping openings used to tightly connect adjacent connecting arcs. Furthermore, it has been experienced that such bolt-receiving openings for connecting arcs must be positioned with a high degree of accuracy. 3 This paper size applies to China National Standard (CNS) A4 specifications (210 X 297). Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. 483995 A7 B7. 5. Description of the invention (>) It is known that there are other structures that can The arcs are brought into circumferential alignment. U.S. Patent No. 3,895,833 to Thiessen provides a flange adapter that can be used in this situation. Thiessen's flange adapters include one or more connecting arcs that are bolted to each other in an end-to-end manner, where the bolts are used to make the respective connecting arcs Fastened directly to the flange of the fitting. When the connecting arc is assembled on the grooved pipe, Thiessen utilizes a beveled cam that engages at the end of each arc. The structure of the bevel cam allows the circular arc tube joints to move in a circle when the bolts are tightened downwards. This allows each flange arc to descend to its lowest point to reach the bottom wall of the groove formed in the fitting, and provides circumferential alignment between the fitting and the fitting. 4 However, such a bevel cam has a defect that the flange cams must be assembled relative to each other before the traction bolt is inserted, and the bevel cams on the individual flange cams are fitted to each other ", or each arc The width of the key of the sheet must be slightly smaller than the width of the groove of the pipe. However, assuming that a key is not completely seated in contact with the side wall of the groove on the pipe, a flexible connection will be formed instead of the rigid connection between the desired pipe and the related fitting. This connector does not provide a radial positioning mechanism, so it cannot be guaranteed that the flanged arcs are truly concentric with respect to the longitudinal axis of the combined arcs, and therefore there is no guarantee that the longitudinal axis related to the pipe is concentric. The bolts in the bolt pads of each flange arc can move freely, which will allow the end of each flange arc to be displaced relative to the side-by-side flange in a radial direction. The displacement distance is equal to the bolts of each flange arc.

Description of the invention (today) To bolt each arc The difference between the bolt diameters of each other. Also, the bevel cams of the Thiessen mechanism, due to the radial extension of the connecting main shaft, cannot provide any force, which acts to move each flange arc. It enters into a concentric relationship with the central axis of the connector. If the flange arcs are not aligned concentrically, the above situation will be a problem when the flange arcs are bolted to the fitting. As a result, the connection arcs and the Will not descend properly to the bottom wall of the pipe groove until The connection with the bottom wall of the groove of the pipe fitting causes the connecting arc piece and the bottom wall of the pipe fitting concave # to be forced into a concentric relationship. However, when tightening the bolt, in order to reduce the diameter of the flange connection piece, the There is considerable frictional resistance, and its resistance to any radial movement of the flanged arcs relative to each other results in that the flanged arcs are not truly concentric with respect to each other. Therefore, there is no guarantee that the flanged arcs are actually correct. Displace down to fully fit the bottom wall of the groove of the fitting. If the flange arc does not actually drop to fully fit the bottom wall of the groove of the fitting, the strength of the interconnection will be affected by the poor material quality. The rigid connection between the flanged arcs may not be achieved. In such a case, the pressure that the connector can withstand will be reduced. Smith U.S. Patent No. 696,603 discloses a method having two pairs of each other. Coupled protruding and recessed pipe fittings. One pair is used for the initial positioning of two adjacent flanged arcs during the initial combination of flanged arcs. The other pair is for flanges The film is used for positioning in the circumferential direction. Similar to the situation of Thiessen, the structure does not provide two adjacent links. 5 The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) ---- --------- Installation -------- Order --------- (Please read the precautions on the back before writing this page) Printed 483995 A7 B7 V. Description of the Invention (p) The radial positioning mechanism of the arc piece, therefore, the Smith patented structure does not automatically provide the concentric positioning of the arc connecting the pipe piece with the pipe piece. [In summary of the invention] The purpose of the present invention is to provide an arc flange connector, which can move into the concentric relationship with respect to each other in the circumferential direction and the diameter direction before and when the traction bolt is tightened, and also makes the bottom of the groove of the pipe fitting. Walls form true concentric relationships. This displacement helps to provide an arc flange connector. The fixing of the pipe and the fitting is completely predictable, so that the real rigidity between the pipe and the fitting is achieved in a fully automatic adjustment manner. The present invention Rotating mating surfaces (preferably conical) are used at the bolt receiving openings at each end of each flange arc. These mating surfaces may initially only engage with each other near the concentric position of the flange arc, and then pull the flange arc to the true concentric position when the bolt is tightened down.

During the downward tightening of the connecting arc, the bevel cam 16 passes along the side surface of the cam groove is to generate the closure of the flange connector, and the initial inner diameter is reduced to drive the key 20 to fit in Inside the groove 22. The groove 22 is machined in a known manner around the outside of a pipe member 24 to be connected to the fitting 26. Therefore, tightening the bolt 28 causes the flanged connector to reduce its diameter, and is instead clamped directly on the juxtaposed surface of the fitting 26. The structure of this conventional technology does not provide the flange arc 12 and the η stomach heart. The paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) ------- I ----- -------- Order --------- (Please read the notes on the back to write this page first) 483995 A7 B7 V. Radial calibration of the invention description (,), also can not provide pipe fittings and The rigid connections between the fittings (please read the note on the back to write this page) There are two types of flanged connectors known in the industry. The first is a "flexible connection" that allows the pipe 24 to be limited. Axial movement and angular displacement, the other is "rigid connection", which inhibits axial movement of the pipe, and also inhibits angular displacement of the pipe. It will be clear from the following discussion of Figs. 2a-2c that the connection of this conventional technology is not an effective "rigid" connection, and, in the design designed to provide a "rigid" connection, it can only provide random And rigid in unpredictable ways. As shown in Figure 2a, when the flanged arcs 12 and 14 are combined on the pipe, the flanged arcs 12 and 14 cannot be automatically aligned radially. Therefore, the combination is not a true concentric arrangement, especially when When the circular shape of the tube 24 is aliased. The bolt openings 30 and 32 in the flange arcs 12, 14 respectively must be made much larger than the bolt rod diameter 28. This is necessary in order to allow the beveled cam 16 to be moved down to the cam groove 18 to provide the necessary flange arcs 12, 14 to be screwed into the pipe groove. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. However, as shown in Figure 2a, the oversized size of the bolt openings 30 and 32 may cause the respective flanged arcs 12 and 14 to be generated in their diameter direction relative to each other. Deviation. Unless the center generated by each flange arc 12, 14 is correctly located on the X-X axis in Fig. 2a, the inclined cam 16 and the cam groove 18 will form a misaligned fit. During the tightening of the bolt 28, this deviating relationship will still exist; because there is no force available to adjust the relative position of the bolt pads of each flange arc 12 and 14 in the radial direction of the YY axis, so that the flange arc Forms true concentricity with the pipe axis Z. 11 This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) ^ «3995 A7 __B7_____ V. Description of the invention () As shown in Figure 2b, the bevel cam 16 and cam groove 18 The mutually matching surfaces are initially joined in a relationship deviating from the YY axis. As shown in Figure 2c, this deviation relationship will not only persist until the key 20 fits into the bottom wall of the groove 22 of the pipe, it can also provide a calibration force along the YY axis, but they must therefore be of sufficient size to overcome the following The resulting frictional motion; (a) the fit of the beveled cam 16 and the cam groove 18; (b) the fit of the flange arc 14 and the fitting 26 under a strong compression pressure; and (c) the traction bolt The nut of 28 fits the friction of the flange arc piece 12. Furthermore, after the bevel cam 16 and the cam groove 18 are included, a general method of combining a flange connector with a pipe cannot be adopted. The "general method" refers to inserting a bolt through a flange receiving hole through a bolt receiving opening at the end of the flange arc in parallel, and then swinging the flange arc around the main axis of the bolt to make it open. The edge arc is positioned above the pipe. Before the key of the flange arc is penetrated into the pipe groove 22, the bolt is inserted into the bolt hole in the fitting to initially fix the flange arc to the fitting. This allows the diameter to be opposite. The bolt is then passed through the bolt receiving opening of the other end of the flange arc, and then passes through the bolt hole of the accessory. Because the required bevel cam and cam groove include the axis parallel to γ_γ and Υ-Z The surface is an angularly extending plane, and unless the bevel cam and the cam groove move in opposite directions along the bolt main axis relative to each other, the Thiessen type flange arc cannot pivot relative to the main axis of the screw inspection. Therefore, this The combination of this conventional technique requires different joining modes. The flange arc 14 must first be moved so that its key 20 fits into the groove 22 of the fitting.

Description of the invention (The rear flange arc 12 must be moved to the flange arc first 14 at the appropriate position, and then the key 20 is fitted into the pipe groove 22. Next, two radially opposite bolts must be passed through the end of the flange arc and through the holes of the fitting 26. That is, In this method, there is no chance to allow the flange flanges to swing to an expanded position. There is no opportunity to shake the arcs into an expanded state, fix them to the fitting 26 in the expanded state, and then pipe the grooved pipe. 24 is positioned to receive the key 20 of the flange arc, then swing the flange arc into a concentric configuration ', and then insert the radially opposite bolts, and finally the two opposite bolts are tightened downward to produce a group Intermediate bolt receiving holes are usually provided between the ends of the respective flanged arcs to receive additional bolts. After the flange connector is initially assembled on the pipe and in the fitting, these bolts are then inserted through Past each flanged arc and accessories, The flange connector is fully fixed to the fitting. If the Thiessen flange arc is really on the same axis as described above, the key of the flange arc will not be outside the pipe and The bottom wall of the groove in the pipe is truly concentric. As a result, when the connector is tightened downward, the key and the bottom wall of the groove of the pipe are still not concentric. This f will adversely cause the radial opposition around the groove of the pipe. At the position, the key on the flange arc forms a point-to-point joint with the bottom wall of the groove, and the gap between the key and the bottom wall of the groove of the pipe is formed at all intermediate positions of those contacts. This excludes the provision of a flange arc connection The possibility of a rigid connection between the fitting and the bottom wall of the pipe groove. The clamping force exerted by the key on the bottom wall of the pipe groove is continuous along the bottom wall of the pipe groove, and all The positions are roughly the same. 13 Wood paper size applies to China National Standard (CNS) A4 specification (210 X 297 public) ----- I-^ · III I ---- (Please read the (Note ^ write this page) Ministry of Economy Wisdom Printed by the Consumer Cooperatives of the Industry Bureau Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 483995 A7 B7 V. Invention Description (/ i) Please refer to Figure 3-6, which is based on Smith's US patent case No. 696,603 The clamp ring for pipe connection of the conventional technology of the No., the semi-circular arc piece A includes an alignment structure which can be locked to each other at its opposite ends to provide only the alignment of the connecting arc pieces in the circumference. The alignment of this circumference is through a common meshing groove or depression /, wherein the cross section of a3 is preferably V-shaped, and it is arranged radially with respect to the center of the connecting arc A. Relative to The other part of a3 is provided with a rib or protruding part a4, whose shape and size are exactly the same as the recessed part a3, and when the two connecting arcs A are pulled together, they can fit into it correctly, and the rib a4 It is also preferably arranged radially with respect to the center of the ring portion. It is particularly noted that the ribs a4 and the recessed portions a3 that are engaged with each other are separated by the opening B that receives the connection bolt C. To assist in the preliminary assembly of the potentially heavy circular arc A, Smith provided a fixed stop button a5 that can loosely enter the hole or recess a6 of another part at one of the overlapping f points of each accessory. The stop button a5 is used to hold the two arc pieces A together near the pipe until the clamping bolt C is inserted and positioned. In particular, the interengagement between a5 and a6, which are also separated by the receiving bolt opening B, is only to provide the initial positioning of the arc A but it does not provide any alignment.

Description of the invention (/ >) In Figures 2a to 2c, when the flange connector When the circumferential shrinkage of the pipe is completed, no force is generated during the downward tightening of the flange connector to radially move the flange arcs 12 and 14 into true concentricity. The present invention provides a structure that enables each flange arc to be automatically moved to a truly concentric position while tightening the connector bolts downward, causing the keys of the flange arc to be concentric with the bottom wall of the groove of the pipe. This system ensures the tight engagement of the key of the required arc with the groove of the fitting, and therefore provides a truly predictable "rigid" connection between the fitting and the fitting, that is, the axial and angular displacement of the fitting relative to the fitting. For restricted links. 7a-7c, according to the present invention, mating surfaces are provided at the respective ends of the arcuate flanged arc pieces 50 and 52, which not only provides the movement of the flanged arc pieces in the XX axis direction, but also causes them to move along γ -The γ axis moves radially. This omnidirectional movement occurs when the flange arcs move relative to each other along the Z axis. According to the present invention, the rotating interengaging surfaces 54, 56 surround the bolt receiving openings at the ends of the arcuate connecting arc pieces 50, 52. These engaging surfaces 54, 56 are conical surfaces, as best shown in Figures 11, 14 and 15. Alternatively, the rotating interengaging surface may be provided by a sphere surface having a female concave surface and a male convex surface, or a surface bounded between a cone and a sphere surface, or a combination thereof. One of the connecting arcs may also have the same intermeshing surface, that is, the two ends of an arc are female-female or male-male, which are opposite to the corresponding ones on the next adjacent arc or arcs. Surface engagement. However, this is not the better one, because it will produce different arcs, and the arcs discussed in the mesh are based on the 15 ^ paper size applicable to the Chinese National Standard (CNS) A4 specification (210x 297 mm)- ----------- install -------- order ---------- line (please read the precautions on the back first to write this page) 483995 A7 B7 V. DESCRIPTION OF THE INVENTION (//) 'An arc resulting in a homosexual configuration. As shown in FIG. 7b, if one of the intermeshing surfaces 54 is a female conical surface and the other intermeshing surface 56 is a male conical surface, when the male intermeshing surface 56 is not true concentric with the female intermeshing surface 54 When the female interengaging surface 54 appears at any position of the surface, when these surfaces move toward each other along the Z axis, these surfaces will gradually move to a truly concentric position, as shown in FIG. 7c. Therefore, when the flange arcs 50 and 52 are not in the true concentric position when they are initially combined, when the bolts connected by the arcs are tightened, the relative movement between the intermeshed surfaces 54 and 56 is on the intermeshed surfaces 54 and As 56 approaches each other along the Z axis, the flange arcs 50 and 52 are moved to a true concentric position. In addition, since each of the interengaging surfaces 54 and 56 is a rotating surface, they do not prevent the respective flanged arc pieces 50 and 52 from swinging relative to each other to enter an unfolded state. In fact, this rocking motion of each flanged arc piece 50 and 52 is very helpful for the next moving the intermeshing surfaces 54 and 56 to a position that is truly concentric with each other, as shown in Fig. 7c. Therefore, when the connecting bolt is inserted through the bolt receiving opening at one end of the respective flange connection arc, the flange connection arc can be easily positioned over the pipe in the unfolded state. The tie bolt is then tightened with fingers to move the interengaging surface to a true concentric position. A bolt is then inserted through the bolt receiving opening through the other end of the flange connection arc, and at the same time, the flange connection arcs 50 and 52 are positioned in the correct direction when the bolt is screwed into the groove of the pipe fitting. When on the bottom wall, the flange connecting arcs are in a true concentric position. At this time, the paper size of the flange arcs 50 and 52 with a diameter of 16 is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) ------------- installation—— (Please read the notes on the back of Qin 4 first to write this page). Line-Printed by the Employees 'Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Printed by the Employees' Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Printed by 483995 A7 The interengaging surfaces 54 and 56 of the ends will engage, and further operations insert the traction bolt and apply torque to the traction bolt 'to further move the flanged arcs 50 and 52 into each other's true concentric position' and also to the pipe fittings The true concentric position of the bottom wall of the shaft and the groove of the pipe fitting. Now referring to FIG. 8, there is shown the flange arcs 50 and 52 meshing at one end with each other, and the flange arcs are configured to be unfolded to allow borrowing. The flange arc is positioned on the pipe 24 by loosely passing the traction bolt (not shown) through the overlapping bolt holes 30-32 'and using the traction bolt as a pivot pin'. Alternatively, also You can fix a bolt first Fix it on the fitting 26 (such as the fitting in Figure 1), and then pass the bolt holes 30-32 of each flange arc through the shaft and the pipe of the bolt. Therefore, this bolt acts as a The pivot pin of the main shaft allows these connected arcs to be freely pivoted into the unfolded state. Another alternative method is shown in FIG. 23, the flange arcs 50, 52 can be permanently and loosely hinged to a bushing 70. The arc pieces 50 and 52 can thus be swung inwardly to engage with the groove 22 of the pipe, so that the opposite bolt receiving holes 30 and 32 can be brought into an aligned state, and at the same time, the keys 20 of the respective flange arc pieces are positioned on the pipe. The groove 22 is followed by passing a bolt through the bolt receiving holes 30 and 32 at the opposite ends of the flange arc, and applying a torque to tighten it. It will be at the opposite end of the respective flange arc 50 and 52. Tighten the bolts downward, and then move the bolt holes 30 and 32 to a position that is truly concentric with the main axis of the traction bolt by the effect of the interlocking conical surfaces 54 and 56 near the bolt receiving holes 30, 32. And then move the respective flange arcs 50 and 52 Enter the true concentricity with each other, and also apply the Chinese National Standard (CNS) A4 specification (210 X 297 mm) with the paper size of the pipe fitting mouth ------------- I ----- Order · --I ----- (Please read the precautions on the back first ~ Fill in this page) 483995 A7 _______B7__ 5. Description of the Invention (Μ) The bottom wall of the groove 22 is truly concentric. (Please read the attention on the back first Write this page again) Except for moving the key 20 to be truly concentric with the bottom wall of the groove 22 of the pipe, the pipe itself is not fixed at this time and resists the movement in a plane perpendicular to the long axis of the pipe. The connecting arc will be adjusted to the proper position to further confirm that the bottom wall of the pipe groove and the respective keys on the flange arcs 50 and 52 are truly concentric. In addition, due to the conical shape of the intermeshable surfaces 54, 56, the respective ends of the arc pieces 50, 52 and their respective keys will be moved in opposite directions with respect to the z-axis, as indicated by arrow Z2 in Figs. 9 and 11. This would be advantageous to cause the key 20 to be clamped on the adjacent sides of the recess 22, thereby providing a truly rigid flanged connector. FIG. 9 illustrates that the required female interengaging surface 54 and male interengaging surface 56 can be provided on the opposite ends of the arc 52, and the flange arc 50 corresponds to the flange arc 52, so that the connecting arc appears true. Male and female. This system advantageously requires only a single configuration of flanged arcs, eliminating the problem of storing two or more differently configured arcs. What's more important is that it eliminates the possibility that an accidental worker might mistakenly combine an incorrect flange connection arc on another mismatched flange arc. The Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs prints whether a flanged connector has two flanged arcs, three flanged arcs, or more such flanged arcs. Provide the required flange connector. If one of the flanged arcs appears to the other flanged arc in an incorrect orientation, the flanged arcs will not cooperate with each other, thus providing a direct message to the staff to let them know of one of the flanged arcs.

The description of the invention () is incorrect. Alternatively and preferably, the textures and surface textures on the opposite sides of the respective flanged arcs are different from each other to provide a tactile sensation for the staff to correctly orient the respective arcs. Therefore, as shown in Figs. 8 and 13, the surface to be presented outward of the flange connector is preferably a smooth surface. As shown in Figures 10 and 12, the opposite sides include spokes that project radially and circumferentially. This provides a tactile and visually observable cue for the desired correct orientation of the flanged arc, and also prevents the flanged arcs from incorrectly combining with each other. In order to assist the connector to close from the unfolded state as shown in FIG. 8 to the closed state as shown in FIG. 10, a preferred method is to provide an ear plate 60 at the opposite end of each flange arc, which is provided by pliers or a kind of The traction device in the form of a yoke can be engaged, but it should be understood that the main closing force comes from the meshing of the surfaces 54, 56 when the bolt is tightened. In addition, as is common in the art, some additional bolt receiving holes 62 are provided at the middle position of the end of each flange arc. Fig. 11 is a perspective view schematically illustrating that the rotating surfaces provided with the interengageable surfaces 54 and 56 are arranged on the connecting arcs 50 and 52, respectively. As previously explained, the rotating surfaces 54, 56 around the openings 30, 32 of the receiving bolt include a conical surface that can be engaged with each other. Therefore, when the flange arcs 50 and 52 move close to each other along the XX axis, even if the arcs are initially misaligned, the reaction force generated by the relative movement along the XX axis will gradually force the arcs into true concentricity with each other. position. The use of conical surfaces is only selective. For example, the female intermeshing surface can also be in the form of a sphere surface, and the male intermeshing surface 56 can also be a sphere surface. _ 19 This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) ) (Please read the notes on the back before filling out this page) -ii I--n-1 i · ninn «I n II I line 丨 483995 A7 5. The form of the invention description (//) The female engaging surfaces 54 have the same diameter. (Please read the back: Cautions Qin 4. Write this page first) As shown in Figure 9, the male and female rotating surfaces 54, 56 can be a shorter axial length to help connect the arcs 50, 52. The connecting key 20 can be easily fitted into the groove 22 of the pipe fitting and cooperate with each other between the rotating surfaces. In addition, as shown in Figures 9 and 11, the cooperation of the rotating surfaces and the tightening of the bolts will cause the adjacent ends of the arc to move in the direction of the arrow Z2 in the opposite direction relative to the ZZ axis and move to XY The opposite side of the face, because the keys on each arc deviate at the ends of the respective arc and move into the side walls that interact with the pipe groove 22 to engage in a clamped manner. Figures 12 and 13 are perspective views showing the opposite sides of one of the connecting arcs such as 50 and 52. Each of these connecting arcs includes a conical male rotating convex surface 56 around one of the bolt receiving openings 32, and an opposite bolt connection opening 30 about the connecting arcs 50, 52.

Description of the invention ('7) The arc-shaped connecting arc has been disclosed in the commonly provisioned U.S. Patent Application No. 09 / 368,680 on August 5, 1999. This concept provides a perturbation relationship, which is related to Used when trying to connect arcs of similar size. When used in conjunction with the present invention, a connecting arc piece 50-1 of a similar size is provided around the rotation convex surface 56-1 of the bolt receiving hole 32-1, and at the opposite end thereof around the bolt receiving hole 30-1. The rotationally connected concave surfaces 54- 丨 are reversed from the positions of the rotational surfaces 54 and 56 of the aforementioned connecting arc 52. Therefore, as shown in Figure 20-22, the final surfaces of the arched arc pieces 52 and 50-1 are in a relationship of mutual interference and eye interference, thereby preventing the connection of similarly-sized connecting arc pieces. FIG. 23 shows another alternative embodiment of the present invention, in which two adjacent connecting arcs 50 and 52 are initially loosely connected by a bushing 70 in an articulated manner, wherein the bushing 70 is Bolt-receiving openings 30, 32 extending through the overlapping arcs. The bushing will have to be able to allow the complementary rotating conical surface to move to a suitable surface contact position. Then insert a tightening bolt into the bushing 70. Although this configuration makes each arc piece 50, 52 easier to handle, it can be used for a tube 24 of a desired shape with less eccentric rotation. After the arc-shaped arc pieces 50 and 52 shown in FIG. 23 are placed near the pipe fittings (not shown in the figure), the bolts are inserted through the two sets of overlapping openings 30 and 32, and the bolts are tightened to connect them. The arc pieces 50, 52 are aligned with the pipe grooves in the circumferential and radial directions. From the foregoing, it should be understood that the positive engagement of the conical rotating surfaces 54, 56 around the respective bolt receiving openings 30, 32 in accordance with the present invention provides improved concentricity and engagement of the key with the groove of the fitting. In addition, in contrast to the previous method of using pliers on the ear plate 60, the use of tightening bolts to 21 paper sizes applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) ---------- --- install -------- order --------- line (please read the notes on the back before writing this page) 483995 A7 ______ B7 V. Description of the invention (y6) Arc The bringing of the tabs 50 and 52 to the alignment position provides a considerable mechanical gain, thereby helping to connect the concentricity between the arcs 50 and 52 and improving the situation where the key 22 is seated in the groove 20 of the pipe fitting. , Which also strengthens the safety pressure that the connector can withstand. A further advantage of the present invention is that the way in which the connecting arcs 50, 52 are guided around the intermeshing conical surfaces 54, 56 of the receiving bolt openings into the concentric position allows the bolt receiving openings to be less precise during manufacture. This system advantageously simplifies and reduces manufacturing costs. A further advantage of the present invention is that the cone-shaped intermeshing surface around the bolt receiving opening provides a more rigid connection compared to the planar contact constructed by the typical techniques of the prior art. Therefore, the arc flange connector of the present invention provides many functional advantages, enhanced assembly procedures, and superior performance compared to previously known arc flange connectors. Although the present invention has been described in connection with its preferred embodiment, 'other modifications will remind itself to those related to the arc flange connector' all points of description are considered to be within the field and spirit of the invention 'such as Defined by the scope of the following patent applications. ------------- Installation -------- Order --------- line (please read the notes on the back first to write this page) Intellectual Property Bureau of the Ministry of Economic Affairs Printed by Employee Consumer Cooperatives 22 This paper is sized for China National Standard (CNS) A4 (210 X 297 mm)
