Description

Technical Field

[0001] This utility model relates to a splicing and assembly conveying pipeline, belonging to the field of conveying pipelines. Background Technology

[0002] Nowadays, in chemical plants or polymer material industrial parks, all equipment is connected by pipelines. Therefore, the connection between pipelines has become an important part of the transportation process. However, in addition to the transportation of finished chemical materials as high-pressure liquids, there is also the transportation of raw materials in the initial steps. A large number of equipment will vibrate during the production process. After vibration, the bolts of traditional transportation pipelines will loosen, which can easily lead to leakage. Summary of the Invention

[0003] Based on the problems described in the background, the problem to be solved by this utility model is to provide a splicing and assembly conveying pipeline, which solves the problem of leakage easily caused by equipment vibration by modifying the flange and adding a splicing component.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A splicing and assembly conveying pipeline is provided, comprising a conveying pipeline, flanges and gaskets, locking components, flange studs, flange nuts, locking studs and locking nuts. The conveying pipeline consists of two sets, with flanges welded to the junction of the two sets of conveying pipelines. Gaskets are sandwiched between the two sets of flanges. The two sets of flanges are fastened together by flange studs and flange nuts. Four sets of locking components are arranged in pairs on the conveying pipelines and simultaneously installed in conjunction with the flanges and flange nuts. The corresponding sets of locking components on the two sets of conveying pipelines are fastened together by locking studs and locking nuts. The corresponding sets of locking components on the same set of conveying pipelines are fastened together by bolts and nuts.

[0005] The locking assembly is further provided with a cylinder, a ratchet, a hexagonal sleeve, a locking plate one, a locking plate two, a locking hole one, and a locking hole two. Three sets of cylinders are evenly distributed inside the locking assembly. The bottom of the cylinder is provided with a ratchet, and the inside of the cylinder is provided with a hexagonal sleeve. At the same time, the top of the hexagonal sleeve is not flush with the top of the cylinder. Locking plate one is horizontally arranged on both sides of the locking assembly. Locking hole one is opened at the center of the locking plate one. Locking plate two is vertically arranged at the top of the locking assembly. Locking hole two is opened at the center of the locking plate two.

[0006] The presence of the ratchet prevents the cylinder from rotating in the direction where the bolt is loosened, thus avoiding the problem of loosening due to vibration.

[0007] The flange is also provided with a mating slot, which is located around the corresponding bolt hole on the flange.

[0008] Preferably, the locking assembly is also provided with rounded corners. The rounded corners are formed at the junction of the hexagonal sleeve and the inner wall of the cylinder. The rounded corners allow the locking assembly to be manually rotated to the correct direction before being directly fitted to the corresponding flange. Under the action of the rounded corners and the ratchet, the cylinder can be rotated to align the hexagonal sleeve with the nut.

[0009] Preferably, the locking assembly is specifically a flange nut fitted onto the flange by a hexagonal sleeve, and the cylinder of the locking assembly extends into the mating slot of the flange to complete the mating use.

[0010] The beneficial effects of this utility model are:

[0011] 1. The presence of the mating slot on the flange allows for better alignment of the cylinder on the locking assembly, while also preventing deviations caused by vibration.

[0012] 2. The presence of a ratchet at the bottom of the cylinder allows the cylinder to rotate in the tightening direction, but it cannot rotate in the loosening direction, thus preventing the bolt from loosening after vibration.

[0013] 3. The locking assembly has three sets of cylinders inside. The multiple sets of cylinders prevent a single cylinder from rotating on its own and also enhance the strength of the locking assembly.

[0014] 4. The rounded corners allow for easy manual rotation of the locking components during installation. The components can then be directly fitted onto the corresponding flange. The rounded corners and ratchet allow the cylinder to rotate, aligning the hexagonal sleeve with the nut. Excessive positioning of the cylinder is unnecessary.

[0015] 5. The entire set of equipment is easy to assemble and install, and simple and convenient to operate. Attached Figure Description

Detailed Implementation

[0022] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0023] Example 1

[0024] like Figures 1-5 As shown, this utility model includes a conveying pipe 1, a flange 2 and a gasket 3, a locking assembly 4, a flange stud 12, a flange nut 13, a locking stud 14 and a locking nut 15. The conveying pipe 1 consists of two sets, with flanges 2 welded to the junction of the two sets of conveying pipes 1. A gasket 3 is sandwiched between the two sets of flanges 2. The two sets of flanges 2 are fastened together by flange studs 12 and flange nuts 13. The four sets of locking assemblies 4 are mounted in pairs on the conveying pipe 1 and are installed in conjunction with the flanges 2 and flange nuts 13. The two sets of locking assemblies 4 corresponding to the two sets of conveying pipes 1 are fastened together by locking studs 14 and locking nuts 15. The two sets of locking assemblies 4 corresponding to the same set of conveying pipes 1 are fastened together by bolts and nuts.

[0025] The locking assembly 4 is also provided with a cylinder 6, a ratchet 7, a hexagonal sleeve 8, a locking plate 10, a locking plate 21, a locking hole 16, and a locking hole 27. Three sets of cylinders 6 are evenly distributed inside the locking assembly 4. The bottom of the cylinder 6 is provided with a ratchet 7. The cylinder 6 is provided with a hexagonal sleeve 8 inside. At the same time, the top of the hexagonal sleeve 8 is not flush with the top of the cylinder 6. The locking plate 10 is horizontally arranged on both sides of the locking assembly 4. The locking hole 16 is opened at the center of the locking plate 10. The locking plate 21 is vertically arranged at the top of the locking assembly 4. The locking hole 27 is opened at the center of the locking plate 21.

[0026] The presence of ratchet 7 prevents cylinder 6 from rotating in the direction where flange nut 13 is loosened, thus avoiding the problem of loosening after vibration.

[0027] The flange 2 is also provided with a mating slot 5, which is located around the corresponding bolt hole on the flange 2.

[0028] The cylinder 6 is inserted into the slot 5 to position and lock the components, thus preventing deviations caused by vibration.

[0029] The locking assembly 4 is also provided with a rounded corner 9, which is located at the junction of the hexagonal sleeve 8 and the inner wall of the cylinder 6.

[0030] The rounded corner 9 allows the locking assembly 4 to be manually rotated to the correct general direction before being directly fitted to the corresponding part of the flange 2. Under the action of the rounded corner 9 and the ratchet 7, the cylinder 6 can rotate in the direction of tightening the bolt, thereby aligning the hexagonal sleeve with the nut in sequence, without the need for excessive positioning of the cylinder.

[0031] The locking assembly 4 is specifically fitted onto the flange nut 13 on the flange 2 via a hexagonal sleeve 8, and the cylinder 6 of the locking assembly 4 extends into the mating slot 5 of the flange 2 to complete the mating use.

[0032] In use, first align the two flanges 2 normally, place the gaskets 3, tighten the flange studs 12 and flange nuts 13, then rotate the cylinder 6 on the locking assembly 4 to the approximate position, and then align it with the corresponding slot 5. Under the action of the rounded corner 9, the cylinder 6 rotates so that the hexagonal sleeve 8 aligns with the flange nut 13. Then push the locking assembly 4 in to align it, and then fix it through the locking hole 17 of the locking plate 11 using the locking bolts 14 and locking nuts 15. Finally, fix it with normal bolts through the locking hole 16 on the locking plate 0 to complete the entire assembly.
