Flanges (110, 210) are formed at both ends of the upper and lower clamps (100, 200), and the upper and lower flanges (110, 210) are provided with bolt holes (1) so that the upper and lower flanges (110, 210) can be coupled by bolts (2) or decoupled. Convex portions (10) and concave portions (20) are correspondingly formed on the abutting portions of the upper and lower flanges (110, 210) of the upper and lower clamps, thus ensuring secure fastening of the flanges. Furthermore, packing is installed inside the upper and lower clamps (100, 200) to prevent leakage. Also, the packing is made of rubber, the convex portions and concave portions are formed on the abutting surfaces of the upper and lower flanges of the pipe clamps, the fastening centers of the flange surfaces are securely aligned when the flanges are fastened, the mating of components is ensured even after the flanges are fastened, and the clamps can be assembled and disassembled quickly and easily. In addition, the packing member inside the clamp has a fluid accommodation portion, which is a space for accommodating fluid that leaks initially, and thus there is a complete absence of fluid leaking to the outside. Also, as the initially leaked fluid is accommodated in the fluid accommodation portion, the pressure exerted by the fluid increases, thereby increasing watertightness, and thus sustained fluid leakage can be prevented. The present invention has the remarkable effect that water tightness can be more efficiently maintained due to the fluid accommodation portions formed at both ends of the packing.

Description

Clamp for pipes with packing joints

[0001] The present invention relates to a pipe clamp to which packing is coupled, and more specifically, to a pipe clamp in which a convex portion and a concave portion are formed on the surface where the upper and lower flanges of the pipe clamp contact each other, so that the center of the flange surface is secure when fastening, and the mutual coupling of the parts is secure even after fastening, and the assembly and disassembly of the clamp is quick and easy.

[0002] In addition, the packing member inside the clamp has a fluid receiving portion formed as a space for initially leaking fluid, so that there is no leakage of fluid to the outside, and furthermore, as the initially leaked fluid is received in the fluid receiving portion, the pressure due to the fluid increases, thereby making the watertightness more effective, thereby preventing continuous fluid leakage, and relates to a pipe clamp in which a packing is combined, in which fluid receiving portions are formed at both ends of the packing, so that watertightness can be maintained more efficiently.

[0003] In general, pipe clamps have been developed for connecting water pipes, etc., and the pipe clamps must be airtight and durable. As an example of prior art, Publication No. 10-1422935 discloses a pipe connection clamp for connecting a pair of pipes, wherein a pair of semicircular clamp bodies are provided, each of which has a flange formed at a connection portion of each pipe and a receiving groove formed between the flanges to receive packing, and the receiving groove is formed to be tapered so that the width becomes narrower from one side to the other.A device connected to a flange for fastening a second pipe to a first pipe and preventing the second pipe from detaching, comprising: a clamping body; a pressing part formed as a separate member from the clamping body and having an inner circumferential surface formed in the shape of any one of a cone, a truncated cone, a polypyramid, and a polypyramidal truncated polypyramid, at least a portion of which includes the bottom edge of the polypyramid and the polypyramid, pressurizing the outer circumferential surface of the second pipe; And a pressing part fixing member provided on the inner circumferential surface of the clamping body part and accommodating the remaining part of the pressing part so that at least a part of the pressing part is exposed toward the center of the clamping body part, the pressing part is arranged so that the apex of the horn faces the detachment direction of the second pipe and the bottom of the horn faces the insertion direction of the second pipe so that movement in the insertion direction is easy and movement in the detachment direction is difficult, the clamping body part is formed by combining at least two or more assembly members formed in a circular arc shape, each end of the assembly member has an extension part extending outward, and a fastening hole for fastening between the assembly members is formed by penetrating the extension part, and when assembling the clamping body part, at least one of the adjacent pairs of extension parts has a spacing part that forms a gap by which the pair of extension parts can be tightened by a bolt inserted into the fastening hole and a nut corresponding to the bolt so that the pair of extension parts can be further pressed between the pressing part and the second pipe by spacing the pair of extension parts apart from each other. The pressurized portion fixing member is formed and a clamp having a constant elasticity toward the center of the second pipe is disclosed.

[0004] In addition, Patent Publication No. 0974605 discloses a pipe connection packing having a ring shape, which is interposed between a female pipe section and a male pipe section to seal between them, wherein a ring groove section is formed on the inner surface of the packing, and a ring surface section of a constant length that is flush with the inner surface of the packing is provided between the ring groove sections so that the ring surface section is intermittently disconnected along the circumferential direction, and a plurality of the ring surface sections are provided at constant intervals along the entire circumferential direction along the ring groove section, and a plurality of the ring groove sections are provided at equal intervals along the axial direction of the packing, and the ring surface sections of the ring groove section are arranged in a zigzag shape with adjacent ring surface sections. In addition, Publication No. 10-2022-0070732 discloses a clamp for pipe connection. However, the above-mentioned conventional technologies have the disadvantages that the center of the upper and lower clamps is uncertain when fastening the pipe clamp, and the mutual connection of the parts is uncertain even after fastening, so that the packing function is reduced and leakage is likely to occur, and it takes a lot of time to assemble and disassemble the clamp, and also, if the packing is used for a long time, leakage occurs, and it is difficult to fasten with the clamp or a defect occurs in the fastening part between the clamp and the packing.

[0005] The present invention has been devised to solve the above-described problems, and the upper and lower flanges of the pipe clamp form a convex portion and a concave portion on the surface where they contact each other, so that the center of the flange surface is secure when fastening, and the mutual connection of the parts is secure even after fastening, and the assembly and disassembly of the clamp is quick and easy.

[0006] In addition, the packing member inside the clamp has a fluid receiving portion formed as a space for initially leaking fluid, so that there is no leakage of fluid to the outside, and furthermore, as the initially leaked fluid is received in the fluid receiving portion, the pressure due to the fluid increases, thereby making the watertightness more effective, thereby preventing continuous fluid leakage. In addition, the present invention provides a pipe clamp in which a packing is combined with a packing in which fluid receiving portions are formed at both ends of the packing to more efficiently maintain watertightness.

[0007] The present invention relates to a pipe clamp to which packing is combined, and is divided into two upper and lower clamps (100, 200), and flanges (110, 210) are formed at both ends of the upper and lower clamps (100, 200), and bolt holes (1) are formed in the upper and lower flanges (110, 210) to be combined or separated by bolts (2), and the portions where the upper and lower flanges (110, 210) of the upper and lower clamps contact each other are formed with corresponding convex portions (10) and concave portions (20) to ensure secure fastening, and packing is installed inside the upper and lower clamps (100, 200) to prevent water leakage.

[0008] In addition, the packing is characterized by being made of rubber.

[0009] Therefore, the present invention forms a convex portion and a concave portion on the surface where the upper and lower flanges of a pipe clamp contact each other, so that the center of the flange surface is secure when fastening, and the mutual connection of the parts is secure even after fastening, and the assembly and disassembly of the clamp is quick and easy.

[0010] In addition, the packing member inside the clamp has a fluid receiving portion formed as a space for initially leaking fluid, so that there is no leakage of fluid to the outside. In addition, as the initially leaked fluid is received in the fluid receiving portion, the pressure due to the fluid increases, making the watertightness even better, thereby preventing continuous fluid leakage. In addition, since the fluid receiving portions are formed at both ends of the packing, there is a remarkable effect of more efficiently maintaining watertightness.

[0053] The present invention is described in detail with reference to the attached drawings as follows. Fig. 1 is a perspective view of a pipe clamp having a fastening surface formed on a flange (contact surface a is a straight line), Fig. 2 is a front view of Fig. 1, Fig. 3 is a perspective view of a pipe clamp having a fastening surface formed on a flange (contact surface a is a diagonal line), Fig. 4 is a front view of Fig. 3, Fig. 5 is a perspective view of a step formed on the contact surfaces of the upper and lower clamps of the present invention, Fig. 6 is a perspective view of a pipe packing of the present invention, and Fig. 7 is an internal view of a pipe packing of the present invention.

[0054]

[0055] The present invention relates to a pipe clamp for connecting left and right pipes. The clamp is mainly made of stainless steel or metal. The pipe clamp is divided into two upper and lower clamps (100, 200), and flanges (110, 210) are formed at both ends of the upper and lower clamps (100, 200), and bolt holes (1) are formed in the upper and lower flanges (110, 210) to be joined or separated by bolts (2). In addition, the portions where the upper and lower flanges (110, 210) of the upper and lower clamps contact each other are formed with corresponding convex portions (10) and concave portions (20) to be fastened.

[0056] The above convex portion is a curve and the corresponding concave portion is also a curved portion. In particular, the cross-section of the convex portion is a semicircle. In addition, for the purpose of joining, one convex portion and one concave portion are formed correspondingly on the flange. The convex portion and the concave portion are formed in the middle of the width direction of the left and right sides of the flange, and the left and right side joining portions, which are the corners of the flange, are formed with curves and are formed with a smaller height than the corresponding right and left side joining portions, so that a gap is formed at the corners where the upper and lower flanges meet. In addition, a gap is naturally formed between the convex portion and the concave portion.

[0057] Therefore, in the present invention, a contact portion is formed in which a portion of the outer surface of the convex portion and a portion of the inner surface of the concave portion come into point contact with each other.

[0058] By the above contact portion, the left and right side joints of the upper flange and the left and right side joints of the lower flange are spaced apart from each other.

[0059] As another example, the upper flange (110) is composed of a straight left-side joining portion (111), a central convex portion (112), and a straight right-side joining portion (113).

[0060] The above lower flange (120) is composed of a straight left-side joining portion (121), a central concave portion (122), and a straight right-side joining portion (123). At this time, the central convex portion of the upper flange may be formed in a trapezoidal cross-section instead of a semicircular one, as shown in Fig. 2 (drawing reference numeral 112). The inner curved portion of the central concave portion of the lower flange, which contacts the hypotenuse of the trapezoidal cross-section, is formed in a curved shape, but may be formed in a straight section corresponding to the straight hypotenuse of the trapezoidal cross-section so as to make linear contact with each other.

[0061] As another example, the central convex portion has a triangular cross-section and the corresponding central concave portion is also triangular. The left and right side joining portions of the upper and lower flanges are formed to be straight lines.

[0062]

[0063] Meanwhile, the upper and lower flanges (110, 210) are formed such that the widths in the left and right directions become smaller as they go outward in the radial direction. In addition, the lower surface of the upper flange (110) and the upper surface of the lower flange (210) are formed with a groove having a square cross-section at a certain position in the radial direction, and when they come into contact with each other, a square hole is formed in the left and right directions. When a pipe is held in a round shape with a pipe clamp based on the square groove, the contacting portion, which is the pipe holding portion, is a straight line where the upper and lower surfaces meet, and the outer side of the straight line where the upper and lower surfaces meet is a flange portion that meets with a convex and a concave portion, as described above. In other words, the contacting portions by the square groove are two places: an inner side that meets in a straight line and an outer side that meets with a convex and a concave portion. The parts that are in contact in a straight line on the inner side can be configured to form a diagonal slope to make the contact surface wider and distribute the force.

[0064] And in the present invention, a packing is inserted into the hollow housing of the pipe clamp to prevent the fluid flowing inside the pipe from leaking to the outside.

[0065] A nut is attached to the above bolt.

[0066] In addition, the present invention can be configured so that the surfaces where the upper and lower clamps are joined are formed with steps as shown in Fig. 5, so that the joining is easy, and the circular rubber packing inside is well joined without being partially caught or pushed by the action of the step surface, so that the seal is secure and there is no leakage. In addition, the step surface prevents the rubber packing from being caught between the upper and lower clamps and bursting, and also prevents it from being distorted.

[0067]

[0068] Meanwhile, the packing of the present invention is a pipe packing that is inserted into a hollow housing as shown in FIGS. 6 and 7 to prevent fluid flowing inside the pipe from leaking to the outside.

[0069] The body of the above packing (100) is in the shape of a hollow body and is composed of an outer circumference (110) positioned outside the pipe, left and right sides (120, 130) formed downward from the left and right ends of the outer circumference (110), and an inner circumference (140) formed toward the center from the left and right sides (120, 130). The inner circumference (140) is divided into left and right inner circumferences (141, 142) by forming a gap (1), and a fluid is introduced and exited through the gap (1), and the packing for the pipe is manufactured by injecting molten rubber into a mold (3000).

[0070] The above outer portion (110) is symmetrical with respect to the center, but the diameter becomes smaller on the left and right sides toward the center, and left and right inclined surfaces are formed respectively.

[0071] On the inner wall surface of the outer portion (110), left and right protrusions (111, 112) are formed downward, and the ends of the left and right protrusions (111, 112) are respectively in contact with the inner wall surface of the inner portion (140).

[0072] The above left and right inner parts (141, 142) are formed symmetrically with respect to the center.

[0073] A step (2) is formed on the outer surface of the left and right inner parts (141, 142), and the step (2) is formed as an inclined surface whose diameter increases as it moves outward from the center of the packing, so that when a pipe is inserted, the left and right inner parts (141, 142) are prevented from being folded toward the outside by the inclined surface.

[0074] The ends of the left and right inner portions (141, 142) protrude vertically downward to form left and right support pieces (151, 152), respectively, so that the outer surfaces of the left and right support pieces (151, 152) support both ends of the left and right pipes into which they are inserted.

[0075] The ends of the left and right support pieces (151, 152) are formed so that semicircular horizontal holes (151-1, 152-1) are spaced apart from each other at regular intervals along the circumferential direction, and semicircular vertical holes (151-2, 152-2) smaller than the semicircular horizontal holes (151-1, 152-1) are formed in the vertical direction inward from the semicircular horizontal holes (151-1, 152-1), so that even if the sides of the left and right support pieces (151, 152) come into contact with each other by the left and right pipes inserted into the interior of the body, the semicircular horizontal holes (151-1, 152-1) come into contact to form a large circular hole shape, and the semicircular vertical holes (151-2, 152-2) also form a small circular hole shape so that the fluid is contained in the fluid receiving portion. This is to ensure easy access to the inner chamber (140).

[0076] The above semicircular vertical holes (151-2, 152-2) are round hole-shaped.

[0077] The above semicircular horizontal holes (151-1, 152-1) are formed in multiple numbers at regular intervals along the circumference of the left and right support pieces.

[0078] Even if the ends of the left and right protrusions (111, 112) formed by protruding downward from the inner wall of the outer circumference (110) of the body by the left and right pipes inserted into the inside of the above-mentioned packing body come into contact with the inner surfaces of the left and right inner circumferences (141, 142), which are the inner surfaces of the body, left and right first flow holes (111-1, 112-1) that are connected to the inner circumference of the fluid receiving portion are formed at the ends of the left and right protrusions (111, 112), respectively, so that fluid can easily flow into the inner circumference of the fluid receiving portion.

[0079] The above first euro hole (111-1, 112-1) is formed in a triangular shape.

[0080] On the inner surfaces of the left and right inner portions (141, 142), left and right second flow holes (141-1, 142-1) each having a triangular shape corresponding to the left and right first flow holes (111-1, 112-1) of the left and right protrusions (111, 112) are formed, so that when the pipe is inserted into the interior of the body and comes into contact with the left and right protrusions (130), the left and right first flow holes (111-1, 112-1) of the left and right protrusions (111, 112) and the left and right second flow holes of the inner surfaces of the left and right inner portions (141, 142) form a square shape.

[0081] The first left and right Euro holes (111-1, 112-1) and the second left and right Euro holes are formed in multiple numbers at regular intervals along the inner circumference of the left and right protruding protrusions (111, 112) and the left and right inner portions (141, 142).

[0082] The left and right first flow holes (111-1, 112-1) formed in the left and right protrusions (111, 112) above are round hole-shaped.

[0083] When the fluid flowing inside the above pipe leaks and flows into the inner circumference, which is the fluid receiving portion, through the first flow holes (111-1, 112-1) on the left and right sides, fluid pressure is formed inside the inner circumference, which is the fluid receiving portion, so that the left and right inner circumferences (141, 142) are firmly pressed against the outer surface of the pipe, thereby making the pipe watertight.

[0084] And in order to prevent the soft material of the rubber packing from being pushed out, the clamp step surface formation described above can prevent the clamp and the rubber from being caught or pushed out when they are tightly connected to each other. In other words, it helps to form a circle precisely by preventing the holes made by the 1st and 2nd flow holes contacting each other and the holes made by the horizontal and vertical holes contacting each other from being crooked and not being in a circle, which causes the flow of the flow to be inaccurate and the pressure to be uneven, resulting in a decrease in the airtightness performance. In addition, the present invention configures the clamp so that the outer diameter of the horizontal length is slightly longer than the vertical length so that the packing is well connected when the clamp is connected, and after connection, the rubber packing is well connected without being caught or pushed out in some part, so that the airtightness is secure and there is no leakage.

[0085]

[0086] Fig. 8 is a cross-sectional view of the packing for the pipe of the present invention.

[0087] This describes the first flow hole (111-1, 112-1) (cone-shaped structure) that serves as the secondary inlet. Due to its conical shape, the internal pressure can be maintained without being lost like a trap.

[0088]

[0089] Fig. 9 shows the structure of the packing for pipe. After the packing for pipe is fastened, pressure is applied through the horizontal holes (151-1, 152-1) and vertical holes (151-2, 152-2) that become the primary inlet of 152-2, and through the primary fluid receiving port.

[0090] This is a side structural drawing of a pipe packing that expands the pipe packing in the secondary fluid receiving port by passing pressure through the first flow hole (111-1, 112-1) of 111-1,111-2 / 141-1,141-2 to strengthen the index force.

[0091] Figure 10 is a front view of Figure 9.

[0092] Fig. 11 is a side view of a packing structure for a pipe in which the pressure flowing into the secondary fluid receiving port increases through the first flow hole (111-1, 112-1) as pressure is applied due to the structural shape (cone) of the first flow hole (111-1, 112-1) that becomes the secondary inlet, but the pressure loss due to the conical structure is small, so the higher the pressure, the stronger the exponential force.

[0093] Figure 12 is a front view of Figure 11.

[0094] Figure 13 is a packing structure for a pipe in which the 151 pipe stopper is formed in multiples so that even if some of them are damaged, the pipe stopper is formed and the index force is not affected even if 151 is damaged.
