Description

Technical Field

[0001] This application belongs to the field of multi-channel rotary joint technology, and particularly relates to a rotary tee joint. Background Technology

[0002] In the aerospace field, rocket fuel delivery pipelines need to be laid between a fixed steel structure and a rotating platform. These fixed steel structures and the rotating platform are connected by flexible hoses that require manual disassembly and reassembly. Because the rotating platform needs to be opened before rocket testing, hoisting, transportation, and launch, and then closed again after testing and launch, this necessitates manual disassembly and reassembly of these connecting pipelines before and after each opening and closing of the rotating platform. Due to the extremely high quality requirements of rocket fuel, each time the pipeline is disassembled and reassembled, resulting in air leakage, requires repeated purging, gas testing, and replacement to prevent condensation and residue buildup. These hoses are large in diameter, numerous, and heavy. The manual operation of these hoses results in extremely poor flexibility and safety, and is time-consuming, severely impacting rocket fueling efficiency and reliability.

[0003] Application content To address the shortcomings of existing technologies, this application provides a rotary tee connector. This solution not only ensures the quality of the transported fuel and effectively reduces manual operation, but also improves the stability of oil transport.

[0004] To achieve the objectives of this application, the following approach is proposed: A rotary tee includes: a housing and a core.

[0005] The top of the outer shell has a circular hole, and the inner wall of the circular hole has multiple annular grooves arranged at intervals from top to bottom. The outer shell is provided with a pipe joint corresponding to each annular groove. The core is a cylindrical structure, which is rotatably located inside the circular hole. The side of the core has horizontal holes that correspond one-to-one with the annular groove from top to bottom. The top of the core has vertical holes that correspond one-to-one with the horizontal holes and communicate with them. The outer wall of the core and the upper and lower sides of the annular groove have sealing structures. The pipe joint and the vertical hole are used for the input and output of oil, respectively.

[0006] The beneficial effects of this application are as follows: 1. This solution avoids frequent disassembly and assembly of pipelines and prevents pipeline punctures, which not only ensures the quality of the transported fuel, but also effectively reduces manual operation, improves flexibility, and simplifies the operation process and technology. 2. During the transportation process, the oil will pass through the annular groove. This structure can effectively stabilize the oil pressure, reduce the impact of the oil, and ensure the smooth transportation of the oil. Attached Figure Description

However, the embodiments described in this application are only some embodiments of this application, and not all embodiments.

[0015] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0016] like Figures 1 to 3 As shown, a rotary tee includes: a housing 1 and a core 3.

[0017] The top of the outer casing 1 has a circular hole 11, and the inner wall of the circular hole 11 has multiple annular grooves 12 arranged at intervals from top to bottom. The outer surface of the outer casing 1 is provided with a pipe joint 2 corresponding to each annular groove 12.

[0018] The core 3 is a cylindrical structure, rotatably positioned within the circular hole 11. The side of the core 3 has horizontal holes 31 corresponding to the annular groove 12 from top to bottom. The top of the core 3 has vertical holes 32 corresponding to and communicating with the horizontal holes 31. The outer wall of the core 3 and the upper and lower sides of the annular groove 12 both have sealing structures. The pipe joint 2 and the vertical hole 32 are used for oil input and output, respectively. In practical use, at least one pipe joint 2 is used for oil return, allowing excess oil to be drained back.

[0019] In practical use, the core 3 or the outer shell 1 can be designed as a fixed installation structure, while the other part is in a free rotation state. No matter what angle the core 3 and the outer shell 1 rotate around the circumference, the oil can flow in the corresponding vertical hole 32, horizontal hole 31, annular groove 12 and pipe joint 2.

[0020] As a preferred embodiment, such as Figure 2 As shown, the outer shell 1 is fixedly installed on the steel structure, the hard oil pipe is connected to the pipe joint 2, the core 3 is in a free rotation state, the upper end of the vertical hole 32 is connected to another section of hard oil pipe, and the oil pipe connected to the vertical hole 32 can drive the core 3 to rotate around the axis, thereby adapting to the change of the included angle of the oil pipes at both ends.

[0021] The above solution effectively avoids the disassembly and assembly of hoses, which not only improves work efficiency but also helps to ensure the long-term cleanliness of the oil pipeline. During the transportation process, the oil will pass through the annular groove 12. This structure can effectively stabilize the oil pressure, reduce the impact of the oil, and ensure the smooth transportation of the oil.

[0022] Preferably, the pipe fittings 2 are arranged in a circumferential array along the outer casing 1 to expand the installation and operation space of the pipe fittings 2.

[0023] Preferably, the horizontal holes 31 and the vertical holes 32 are arranged in a circumferential array. This structure allows the oil pipes connected to the vertical holes 32 to be evenly distributed on the top of the core 3. When the core 3 is rotated by the oil pipes, the circumference of the core 3 can be more evenly stressed, avoiding local wear caused by eccentric stress on the core 3.

[0024] Preferably, each vertical hole 32 is provided with a connecting pipe 4 at its top for connecting a rigid pipe. Specifically, the connecting pipe 4 and the vertical hole 32 can be connected by a pipe thread.

[0025] Preferred, such as Figure 2 , Figure 3As shown, the connecting pipes 4 are all vertically inserted on a connecting plate 41. The connecting plate 41 is fixed to the top of the core 3 by bolts, and a sealing gasket is provided between the connecting plate 41 and the core 3 to ensure the sealing of the connection between the vertical hole 32 and the connecting pipe 4.

[0026] Further preferred, such as Figure 3 As shown, the circular hole 11 penetrates the bottom of the outer shell 1, and the outer side of the top of the core 3 is provided with a raised edge. The bottom surface of the raised edge slides in contact with the top surface of the outer shell 1. The bottom of the core 3 is provided with a limiting disc 33, the top surface of which slides in contact with the bottom surface of the outer shell 1. Under the action of the raised edge and the limiting disc 33, the core 3 can be effectively prevented from moving relative to the outer shell 1 along the axis, thereby ensuring that the transverse hole 31 is always aligned with the corresponding annular groove 12.

[0027] The above description is merely a preferred embodiment of this application and does not imply that it is the only possible embodiment or a limitation thereof. Those skilled in the art should understand that various changes or equivalent substitutions made to this application without departing from its scope are all within the protection scope of this application.
