[0002] In industries such as petrochemicals, food processing, and energy and power, steam serves as a crucial heat source and power medium, requiring efficient transmission and distribution through pipeline systems. With the expansion of industrial production scale and the increase in process complexity, steam transmission systems face challenges such as uneven flow distribution, large pressure fluctuations, and high energy losses. Traditional pipeline components are no longer sufficient to meet the stability, reliability, and energy efficiency requirements of modern production for steam transmission.
[0003] For example, Chinese utility model patent application number 201821902149.9 discloses a steam conveying pipe, which effectively enhances the functionality of steam conveying pipes, solves the problem and shortcomings of the relatively single functionality of existing steam conveying pipes, and also ensures the pipe strength and overall thermal insulation effect, effectively avoiding the risk of pipe cracking, and helping to ensure the service life and working performance stability of the pipe, thus having good practical value and promotion value. However, its device still has certain defects;
[0004] After long-term operation, the inner wall of the manifold is prone to accumulating impurities such as rust, scale, and welding slag. Especially under conditions of high steam humidity, the corrosive ions carried by the condensate will accelerate the corrosion of the inner wall, forming pits or scale layers, making it difficult to disassemble, replace, or clean the manifold.
[0005] Therefore, we propose an industrial steam transmission pipeline assembly with a diversion structure to solve the problems mentioned above. Utility Model Content

[0009] Preferably, four diversion joints are provided, and the diversion joints are connected to the main steam conveying pipe and the diversion pipe.
[0010] The above structural design ensures that the industrial steam flow is evenly distributed to each branch pipe, solving the problem of uneven flow caused by traditional single-branch branching. It is especially suitable for scenarios with simultaneous heating of multiple production lines, improving the operational stability of industrial systems.
[0011] Preferably, the annular groove engages with the first sealing ring inside the diverter, and the first sealing ring is fixedly connected to the inner wall of the diverter.
[0012] The above structural design forms a radial sealing barrier, which, together with the axial contact of the second sealing ring, constitutes a double sealing system, effectively preventing energy loss caused by steam leakage.
[0013] Preferably, the second sealing ring abuts against the right end of the diverter, and the outer diameter of the second sealing ring is larger than the outer diameter of the diverter.
[0014] With the above structural design, the second sealing ring on the diverter pipe can be tightly abutted against the right end of the diverter connector, thereby further improving the sealing performance when the diverter pipe is connected to the diverter connector.
[0015] Preferably, the second fixing ring has a through hole, the threaded rod passes through the through hole, and there are multiple threaded rods and through holes. Fastening nuts are installed on both the left and right sides of the threaded rod, and the fastening nuts on the left and right sides abut against the first fixing ring and the second fixing ring respectively.
