Embodiment Construction
[0033] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0034] Such as figure 2 As shown, the baffle plate structure of the main helium fan of the high temperature gas-cooled reactor provided by the embodiment of the present invention is located at the inlet of the main helium fan, and includes three parts: the conical pipe 1 , the swing check plate and the electric device 8 . Wherein, the conical pipe 1 is an inlet pipe in front of the impeller of the main helium fan, and the small section is adjacent to the impeller of the main helium fan. The swing check plate includes: a tongue plate 2, a crank arm connecting rod 3 and a rotating shaft 4. One end of the crank arm connecting rod 3 is connected with the tongue plate 2 through...

The invention relates to the technical field of reactor engineering and particularly discloses a baffle structure of a high-temperature gas-cooled reactor primary-helium fan with active and passive characteristics. The baffle structure comprises a conical pipe, a rotary-opening type check non-return plate and an electric device, wherein the main body part of the rotary-opening type check non-return plate is positioned in the conical pipe, and the electric device is arranged at the outer part of the conical pipe; in addition, a special connecting structure is designed for connecting the rotary-opening type non-return plate and the electric device and is specifically characterized in that a key is arranged on a rotary shaft, and a ring-shaped key groove is correspondingly arranged in a shaft sleeve, so that the shaft sleeve has an idle stroke for carrying out 90-degree free rotation around the rotary shaft; according to the different positions of the key in the ring-shaped key groove, the primary-helium fan baffle not only has the passive characteristic of realizing opening and closing by gravity and gas pressure, but also has the active characteristic for realizing opening and closing by the electric device, so that the requirement for multiple working conditions of the high-temperature gas-cooled reactor can be met.
Description
technical field [0001] The invention relates to the technical field of reactor engineering, in particular to a baffle plate structure for a main helium fan of a high-temperature gas-cooled reactor with both active and passive features. 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 overall structure of the primary circuit of a high temperature gas-cooled reactor nuclear power plant is as follows: figure 1 As shown, it includes a reactor pressure vessel 1' and a steam generator pressure vessel 5', which are connected by a hot gas conduit 3'. The reactor core is cooled by helium. The high-temperature gas-cooled reactor relies on the main helium fan to drive the helium coolant to circulate in the primary circuit of the reactor. The main helium ...
