Description

Technical Field

[0001] This application relates to the technical field of marine equipment, and more particularly to a pipeline system and a ship. Background Technology

[0002] In the field of existing shipboard freshwater cooling piping systems, the piping systems encompass numerous devices and have a complex layout. This complex structural characteristic makes it difficult to achieve uniform distribution of freshwater to the various devices, thereby affecting the overall operational efficiency and stability of the system.

[0003] To address the aforementioned issue of uneven water distribution, orifice plates are typically installed at the inlet pipes of many devices. As a key flow control element, the orifice plate works by precisely controlling the flow rate of the medium in the pipeline by adjusting its own opening. During system commissioning, technicians adjust the opening of the orifice plates based on the actual operating conditions of the equipment to ensure that the water entering each device meets the system's normal operating requirements, thereby enabling the entire freshwater cooling system to operate continuously under stable conditions.

[0004] However, conventional adjustable orifice plates present numerous inconveniences in actual adjustment. When adjusting the orifice plate opening, all flanges and fasteners already installed on both sides of the pipeline must be removed, the medium in the pipeline emptied, and the pipeline reinstalled after the opening adjustment is completed. Then, the medium must be re-added to the system, and system verification must be performed. If the verification results still show that the system's usage requirements are not met, the above tedious adjustment process must be repeated, adjusting the orifice plate opening multiple times until the system's usage standards are met. This series of operations not only consumes a lot of manpower but also requires a significant investment of time, severely impacting the efficiency and cost of system commissioning.

[0005] The purpose of this utility model embodiment is to provide a pipeline system and a ship that can solve the above-mentioned problems existing in the prior art.

[0006] To achieve the above objectives, this application adopts the following technical solution: On the one hand, a piping system is provided, comprising: The first tube body has a first tube hole; The second tube body has a second tube hole; A first flange and a second flange are disposed between the first pipe body and the second pipe body; the first flange has a first through hole and the second flange has a second through hole.

[0016] The beneficial effects of this application are as follows: The pipeline system of this application uses threaded connectors to connect and communicate sequentially the first pipe body, the first flange, the second flange, and the second pipe body. A turntable with an eccentric hole is clamped between the first flange and the second flange. The turntable is provided with a first meshing tooth, and the threaded connector is provided with a second meshing tooth.

Although the flowcharts describe the operations (or steps) as sequential processes, many of these operations can be performed in parallel, concurrently, or simultaneously. Furthermore, the order of the operations can be rearranged. The process can be terminated when its operation is completed, but it may also have additional steps not included in the figures. The process may correspond to a method, function, procedure, subroutine, subroutine, etc.

[0025] Unless otherwise stated or defined, the term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0026] like Figures 1 to 4 As shown, this embodiment provides a pipeline system including a first pipe body 11, a second pipe body 12, a first flange 13, a second flange 14, a turntable 15, and a threaded connector 16.

[0027] The first tube body 11 has a first tube hole 111. The second tube body 12 has a second tube hole 121.

[0028] A first flange 13 and a second flange 14 are disposed between a first pipe body 11 and a second pipe body 12. The first flange 13 has a first through hole 131, and the second flange 14 has a second through hole 141. The first flange 13 is connected to the first pipe body 11, and a first pipe hole 111 communicates with the first through hole 131. The second flange 14 is connected to the second pipe body 12, and a second pipe hole 121 communicates with the second through hole 141.

[0029] The turntable 15 is in the shape of a rotating body and has an eccentric hole 151. A rotating body means that when an object rotates around its axis of rotation, each part of it maintains the same shape when it reaches a fixed position. The turntable 15 is similar to a circular tube, and the eccentric hole 151 is a circular hole whose center does not coincide with the axis of the turntable 15. The turntable 15 is clamped between the first flange 13 and the second flange 14. Multiple first meshing teeth 152 are provided on the outer circumferential side of the turntable 15, and these teeth are spaced apart along the circumference of the turntable 15. A first meshing groove is formed between adjacent first meshing teeth 152. The multiple first meshing teeth 152 can be arranged in a full circle around the circumference of the turntable 15, or only partially. In the accompanying drawings of this embodiment, the multiple first meshing teeth 152 are arranged in a half-circumference around the turntable 15, which satisfies the flow regulation requirements of the pipeline system.

[0030] The threaded connector 16 is equipped with a locking nut 17. The first pipe body 11, the first flange 13, the second flange 14, and the second pipe body 12 are sequentially connected by the threaded connector 16, with their axes coinciding. Each of these components has a connecting hole through which the threaded connector 16 passes; the connecting hole can be a smooth hole or a threaded hole. The threaded connector 16 has a shaft with a certain length of external thread. The threaded connector 16 can have external threads adapted to the locking nut 17 on its entire shaft, or it can have external threads adapted to the locking nut 17 on one or both ends of the shaft. When one end of the shaft of the threaded connector 16 has an external thread, the other end of the shaft has a hexagonal head. This application uses the example where both ends of the shaft of the threaded connector 16 have external threads adapted to the locking nut 17, and locking nuts 17 are installed at both ends of the shaft of the threaded connector 16. The threaded connector 16 connects the first pipe body 11, the first flange 13, the second flange 14, and the second pipe body 12 in sequence, and connects the first pipe hole 111, the first through hole 131, the eccentric hole 151, the second through hole 141, and the second pipe hole 121 in sequence.

[0031] Multiple threaded connectors 16 are arranged at intervals along the circumference of the turntable 15. The threaded connectors 16 do not need to pass through the turntable 15, which is located within the area enclosed by the multiple threaded connectors 16. At least one threaded connector 16 is provided with multiple second meshing teeth 161, which are arranged at intervals along the circumference of the threaded connector 16. The multiple second meshing teeth 161 are used to mesh with first meshing teeth 152, that is, a second meshing groove is formed between adjacent second meshing teeth 161 to mesh with the first meshing tooth 152. The second meshing teeth 161 mesh with the first tooth groove. The meshing principle is the same as that between two gears, which will not be described in detail here.

[0032] When only one threaded connector 16 has a second meshing tooth 161, the remaining threaded connectors 16 can use ordinary bolts, which can save costs. When multiple or all threaded connectors 16 have a second meshing tooth 161, the adjustment will not be difficult due to the inconvenient position of the threaded connector 16 with the second meshing tooth 161. Adjustment can be made more effortless by driving multiple threaded connectors 16 to rotate simultaneously.

[0033] When flow rate adjustment is required, loosen the locking nut 17 so that the clamping force of the first flange 13 and the second flange 14 on the turntable 15 is insufficient to lock the turntable 15. The turntable 15 can rotate around its own axis. By rotating the threaded connector 16 with the second meshing tooth 161, the turntable 15 can be driven to rotate, thereby changing the size of the communication area between the eccentric hole 151 and the first through hole 131 of the first flange 13, and between the eccentric hole 151 and the second through hole 141 of the second flange 14, thus achieving flow rate adjustment. It is not necessary to completely disassemble the threaded connector 16, the first pipe body 11, the first flange 13, the turntable 15, the second flange 14, and the second pipe body 12, so there is no need to vent the medium in the pipeline system. After adjustment is completed, tighten the locking nut 17 so that the first pipe body 11, the first flange 13, the turntable 15, the second flange 14, and the second pipe body 12 are tightly connected, ensuring that the turntable 15 is clamped between the first flange 13 and the second flange 14 and cannot rotate, thus achieving locking after adjustment.

[0034] Thus, this application employs a threaded connector 16 with a second meshing tooth 161 that engages with a turntable 15 with a first meshing tooth 152. By rotating the threaded connector 16, the position of the eccentric hole 151 can be adjusted, i.e., the opening of the turntable 15 can be adjusted in its entirety without restriction, to meet the flow requirements of the pipeline system. This allows flow regulation to be completed without completely disassembling the pipeline system or emptying the medium within it. This application simplifies construction and operation, reduces additional on-site disassembly and assembly work, and simplifies commissioning. It not only reduces the manpower, time, and cost invested in flow rate commissioning but also improves commissioning efficiency.

[0035] In one embodiment, the piping system further includes a first sealing ring 18 and a second sealing ring 19. The first sealing ring 18 is clamped between the turntable 15 and the first flange 13, and the second sealing ring 19 is clamped between the turntable 15 and the second flange 14. Both the first sealing ring 18 and the second sealing ring 19 are O-rings, and the piping system is sealed by the O-rings.

[0036] Optionally, the turntable 15 and / or the first flange 13 are provided with a first sealing groove, and the first sealing ring 18 is disposed in the first sealing groove. The turntable 15 and / or the second flange 14 are provided with a second sealing groove, and the second sealing ring 19 is disposed in the second sealing groove. In this embodiment, the first flange 13 is provided with a first sealing groove, and the second flange 14 is provided with a second sealing groove. The first sealing groove and the second sealing groove facilitate the installation of the first sealing ring 18 and the second sealing ring 19, thereby improving the sealing performance and assembly efficiency of the pipeline system.

[0037] Furthermore, the piping system also includes a first gasket 20 and a second gasket 21. The first gasket 20 is clamped between the first pipe body 11 and the first flange 13, and the second gasket 21 is clamped between the second pipe body 12 and the second flange 14. Specifically, the first pipe body 11 is provided with a first connecting ring 112, which is integrally formed with the first pipe body 11. The first connecting ring 112 is connected to the first flange 13 by a threaded connector 16, increasing the connection area between the first pipe body 11 and the first flange 13. The second pipe body 12 is provided with a second connecting ring 122, which is integrally formed with the second pipe body 12. The second connecting ring 122 is connected to the second flange 14 by a threaded connector 16, increasing the connection area between the second pipe body 12 and the second flange 14. The first gasket 20 is clamped between the first connecting ring 112 and the first flange 13 of the first pipe body 11, and the second gasket 21 is clamped between the second connecting ring 122 and the second flange 14 of the second pipe body 12. The first gasket 20 and the second gasket 21 can enhance the sealing between the two planes to prevent fluid leakage.

[0038] In one embodiment, a first gasket groove is provided on the first pipe body 11 and / or the first flange 13, and a second gasket groove is provided on the second pipe body 12 and / or the second flange 14. A first gasket ring 20 is provided in the first gasket groove, and a second gasket ring 21 is provided in the second gasket groove, which facilitates the installation of the first gasket ring 20 and the second gasket ring 21.

[0039] In one embodiment, the diameter of the first pipe hole 111 of the first pipe body 11 is equal to the diameter of the second pipe hole 121 of the second pipe body 12, and the diameter of the first through hole 131 of the first flange 13 is equal to the diameter of the second through hole 141 of the second flange 14. This ensures precise alignment when the first pipe body 11 and the second pipe body 12 are connected via the first flange 13 and the second flange 14, avoiding installation deviations or inadequate sealing due to dimensional differences, thereby improving connection strength and sealing performance. Furthermore, the equal diameter of the first pipe hole 111 of the first pipe body 11 and the second pipe hole 121 of the second pipe body 12 simplifies the production process, reduces maintenance costs, and enhances system interchangeability.

[0040] Optionally, the diameter of the first pipe hole 111 of the first pipe body 11 is larger than the diameter of the first through hole 131 of the first flange 13, which facilitates installation and adjustment, allows for a certain alignment error when the first pipe body 11 is connected to the first flange 13 or when the second pipe body 12 is connected to the second flange 14, and reduces installation difficulties caused by machining or assembly deviations.

[0041] Optionally, the diameter of the eccentric hole 151 is equal to the diameter of the first through hole 131 of the first flange 13. When the diameter of the eccentric hole 151 is equal to the diameter of the first through hole 131 of the first flange 13 and the diameter of the first through hole 131 of the second flange 14, the turntable 15 can maintain symmetrical force when adjusting the flow rate, reducing local stress concentration caused by eccentricity and extending the service life of the seal. At the same time, this design can ensure the linearity of flow rate adjustment, avoid pressure fluctuations caused by sudden changes in orifice diameter, and improve control accuracy.

[0042] Furthermore, the eccentric placement of the first through-hole 131 on the first flange 13 and the eccentric placement of the second through-hole 141 on the second flange 14 reduces friction on the sealing surfaces, allowing the turntable 15 to quickly disengage from the sealing surfaces of the first flange 13 and the second flange 14 during adjustment, thus reducing wear. Simultaneously, this also improves sealing performance, achieving bidirectional zero leakage through the "tightening as it closes" effect of the eccentric structure, resulting in better opening adjustment.

[0043] In one embodiment, the threaded connector 16 is a screw, and the screw is fitted with two locking nuts 17. The first pipe body 11, the first flange 13, the second flange 14, and the second pipe body 12 are clamped between the two locking nuts 17, thereby improving the reliability and efficiency of the pipeline system regulation.

[0044] This embodiment also provides a vessel, including a hull and a piping system as described in any of the above embodiments. The piping system is installed on the hull. The piping system is mainly used for freshwater cooling of the vessel, providing freshwater to various equipment on board for cooling.

[0045] The technical principles of this application have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this application and should not be construed as limiting the scope of protection of this application in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this application without inventive effort, and these embodiments will all fall within the scope of protection of this application.
