Description

Technical Field

[0001] The utility model relates to the field of pipeline connectors, in particular to a high-strength pipeline direct joint. Background Art

[0002] Ordinary pipe clamps are provided with reinforcing plates on the exposed surfaces of both wings. The reinforcing plates are usually connected to the pipe clamps by welding. The welding process will form welding marks at the welds, and the welding marks are easily cracked due to the tensile force.

[0003] The two wings of ordinary pipe clamps need to be tapped before being tightened with bolts to construct threaded holes for bolt locking. When the two pipe clamps are symmetrically spliced, bolts need to be locked in the threaded holes to achieve tightening. The tensile strength of the bolts is subject to the material strength of the base material where the threaded holes are located. Ordinary pipe clamps are generally made of aluminum, which has poor tensile properties, resulting in the ineffective use of the reinforcement sheet, which is prone to cause pipeline leakage.

The two wings of the first pipe clamp and the second pipe clamp are respectively opened at positions close to the direct channel ports and are plugged and fastened with bolts and nuts. The four exposed surfaces of the two pairs of the two wings are stacked one by one with reinforcing sheets riveted respectively by rivets.

[0016] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] like Figure 1-4 As shown, the embodiment of the utility model includes:

[0018] A high-strength pipeline direct joint comprises a first pipe clamp 1, a second pipe clamp 2, bolts 3, nuts 4, rivets 5, and reinforcing sheets 6. The first pipe clamp 1 and the second pipe clamp 2 are symmetrically spliced ​​with each other and surround a cylindrical direct channel 7. The two wings 8 of the first pipe clamp 1 and the second pipe clamp 2 are respectively opened at positions close to the ports of the direct channel 7 and are inserted and fastened with bolts 3 and nuts 4. The reinforcing sheets 6 riveted by rivets 5 are stacked one by one on a total of four exposed surfaces of the two pairs of the two wings 8.

[0019] Among them, each of the reinforcing sheets 6 is respectively connected and fastened to each group of bolts 3 and nuts 4, the head 31 of the bolt 3 is arranged on one side of the first pipe clamp 1, and the reinforcing sheets 6 stacked on the two wings 8 of the first pipe clamp 1 are provided with step holes 61 matching the bolts 3 and nuts 4, and the head 31 of the bolt 3 is provided with an integrally formed gasket 31 matching the step hole 61.

[0020] Furthermore, the rivets 5 are symmetrically arranged in pairs on both sides of each group of the bolts 3 and nuts 4.

[0021] Furthermore, the nut 4 is arranged correspondingly on one side of the second pipe clamp 2, and the reinforcing plate 6 stacked on the two wings 8 of the second pipe clamp 2 is provided with a limiting embedded groove 62 matching the size, shape and position of the nut 4, and the nut 4 is embedded in the limiting embedded groove 62.

[0022] Furthermore, a circle of concave-convex cavities is coaxially arranged around the inner walls of the first pipe clamp 1 and the second pipe clamp 2, and a pipeline sealing ring 102 is coaxially filled in the concave-convex cavities.

[0023] The pipe clamp is composed of two pieces of semicircular metal materials formed in one piece. Each pipe clamp has two wings 8 formed by stamping. The built-in sealing ring 102 of the pipe clamp is sleeved on the butt joint of the two pipes. The two matched pipe clamps can simultaneously wrap the sealing ring 102 at the butt joint of the two pipes, and then lock the two wings 8 by bolts 3 and nuts 4 to press the sealing ring 102 against the pipe joint, thereby realizing the directness of the pipe.

[0024] The exposed surfaces of the two wings 8 of the ordinary pipe clamp are provided with reinforcing sheets 6, and the reinforcing sheets 6 are usually connected to the pipe clamp by welding. The welding process will form welding marks at the welds, and the welding marks are prone to cracking.

[0025] This product adopts riveting instead of welding to fix the reinforcing plate 6. Under the condition of achieving the same connection strength, it can save welding procedures, simplify the processing technology, and reduce construction and material costs.

[0026] Before being fastened with bolts 3, the two wings 8 of the common pipe clamp need to be tapped to construct threaded holes for fastening with bolts 3. When the two pipe clamps are symmetrically spliced, the bolts 3 need to be locked in the threaded holes to achieve fastening. The tensile strength of the bolts 3 is subject to the material strength of the base material where the threaded holes are located. Common pipe clamps generally use aluminum, which has poor tensile properties, resulting in the reinforcing sheet 6 not being able to be effectively used, which is easy to cause pipeline leakage.

[0027] This product adopts the method of embedding nuts 4 to replace the common tapping process, thereby significantly improving the overall tensile performance.

[0028] In summary, the utility model provides a high-strength direct pipe joint, which adopts the riveting process to realize the installation and fixation of the reinforcement plate 6 on the two wings 8 of the pipe clamp, and replaces the tapping process with the pre-embedded nut 4, which not only overcomes the problem of loose joints caused by metal fatigue, but also greatly simplifies the construction process and effectively improves the construction efficiency.

[0029] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
