摘要： 钠燃烧过程会造成试验厂房内的温度和压力显著升高。试验厂房的门作为厂房边界的一部分，应具备防火隔热和承压密封的功能，但在目前的实际应用中并没有可以满足该要求的工程门。基于此，针对钠燃烧过程的特点，并结合核工程的实际工况，设计了一种兼具防火隔热和承压密封功能的新型隔热密封门。以核工程中不同工况下常用工程门的结构为基础，结合该工程中温度和压力的实际工况，分别设计了隔热密封门的锁紧机构、门板组件、门框组件、铰链和密封条等。同时，通过设计计算分析了锁紧机构零部件的受力情况、门板组件的隔热性能和密封条的选型，并利用ANSYS有限元软件对隔热密封门的门板和压紧杆等关键部件进行了强度分析。最后，根据理论计算结果制作了隔热密封门样机，通过样机试验验证了所设计隔热密封门在280 ℃环境下具有防火隔热和承压密封功能以及较高的可靠性。所提出的隔热密封门设计和分析方法可为后续类似工况设备的设计提供依据和参考。
Abstract: The sodium combustion process will cause a significant increase in temperature and pressure of the test plant. As a part of the plant boundary, the door of the test plant should have the functions of fire and heat insulation and pressure sealing, but there is no engineering door that can meet this requirement in the current practical application. Based on this, according to the characteristics of sodium combustion process and combined with the actual working conditions of nuclear engineering, a new heat insulation sealing door with the functions of fire and heat insulation and pressure sealing was designed. Based on the structure of special engineering doors under different working conditions in the nuclear engineering, combined with the actual working conditions of temperature and pressure in this engineering, the locking mechanism, door panel assembly, door frame assembly, hinge and sealing strip of the heat insulation sealing door were designed, respectively. At the same time, the force of the locking mechanism components, the heat insulation performance of the door panel assembly and the selection of the sealing strip were analyzed through the design calculation, and the strength of key components such as door panel and compression rod of the heat insulation sealing door were analyzed by using the ANSYS finite element software. Finally, according to the theoretical calculation results, the heat insulation sealing door prototype was made. The prototype test verified that the designed heat insulation sealing door had the functions of fire and heat insulation and pressure sealing and relatively high reliability at the environment of 280 ℃. The proposed design and analysis method of heat insulation sealing door can provide basis and reference for the design of equipment under similar working conditions.
