Description

Technical Field

[0001] The utility model relates to a steam generator with a new structure, belonging to the technical field of steam generators. Background Art

[0002] A steam generator is a mechanical device that heats water into hot water or steam. Steam is often transported through pipelines, and the steam pipelines and steam generators need to be sealed to prevent steam leakage.

[0003] In the prior art, refractory materials are often used to fill the steam generator and the steam pipeline to seal them. The refractory fillers will often be oxidized after long-term use, and the sealing effect on the steam generator will be poor. In particular, when the diameter of the steam pipe is smaller than the inner diameter of the installation port, the sealing effect of the refractory material will be poor, and it will be difficult to clean the filling material, making it inconvenient to disassemble and repair the steam generator.

[0004] In response to the above problems, corresponding patents have emerged in the industry to solve the corresponding problems. For example, the authorization announcement number is CN214368271 U, and the patent name is: An improved steam generator sealing member. In the above patent, when the steam pipe is inserted into the steam generator installation port through the sealing member, the gap between the steam pipe and the steam generator is sealed by the sealing member, which solves the problem of poor sealing effect and inconvenience in cleaning and disassembly and maintenance when using refractory materials in the existing technology.

[0005] However, the above patent has the following problems: the sealing member in the above structure is only suitable for the case where the diameter of the steam pipe is smaller than the diameter of the steam generator mounting port. When the diameter of the steam pipe is larger than the diameter of the steam generator mounting port, the sealing member in the above structure cannot be used, resulting in poor adaptability of the existing sealing member and failure to meet the actual installation needs. At the same time, the steam pipe in the above patent only passes through the mounting port and is not fixed to the mounting port, resulting in poor stability. The steam generator will vibrate during operation, and the vibration will cause a gap between the steam pipe and the mounting port, resulting in steam leakage. Summary of the Invention

[0008] Preferably, the transition joint includes a transition duct, a connecting seat plate is provided at the middle position of the outer surface of the transition duct, an exhaust hole is provided on the transition duct, the exhaust hole passes through from one side of the transition duct to the other side, a plurality of outer sealing ring grooves are provided on the outer surface of the transition duct, and a plurality of inner sealing ring grooves are provided in the exhaust hole.
