Abstract

A pressure-bearing flange structure of a high-temperature gas cooled reactor main helium fan comprises a steam generator pressure container flange, a volute flange connected to the upper portion of the steam generator pressure container flange and a middle partition plate connected to the upper portion of the volute flange; the steam generator pressure container flange is connected with the volute flange through a bolt and the volute flange is connected with the middle partition plate through a bolt; the middle partition plate is a partition plate of a main helium fan motor cavity and a main helium fan cavity, wherein the main helium fan motor cavity is located above the axis of the middle partition plate and the main helium fan cavity is located below the axis of the middle partition plate; a plurality of grooves are formed in the bottom face of the middle partition plate and heat insulation layers are arranged on the grooves; the volute flange comprises an outer flange body which is far away from the axis of the main helium fan and an upper flange body which is located along the axis of the main helium fan. According to the pressure-bearing flange structure, the main helium fan motor cavity is separated from the main helium fan cavity, meanwhile, load-bearing, heat-insulation and locating requirements can be met, and safe and reliable operation of the main helium fan is guaranteed. The pressure-bearing flange structure has enforceable performance and brings convenience to installation and overhaul of the main helium fan; meanwhile, the structure is simple and is easy to machine.

Description

technical field [0001] The invention relates to the technical field of high-temperature gas-cooled reactor engineering, in particular to a pressure-bearing flange structure of a main helium fan of a high-temperature gas-cooled reactor. Background technique [0002] The high-temperature gas-cooled reactor is a high-temperature reactor with graphite as the moderator and helium as the coolant. It is an advanced nuclear reactor with good inherent safety, high power generation efficiency, and extremely wide uses. The primary circuit of the high temperature gas-cooled reactor nuclear power plant includes the reactor pressure vessel and the steam generator pressure vessel, which are connected by hot gas conduits. The steam generator pressure vessel includes a fan casing and a steam generator casing. The reactor core is cooled by helium. The helium coolant has a rated pressure of 7MPa and is driven by the main helium blower. It is forced to circulate inside the reactor primary cir...
