Embodiment
[0043] Such as Figure 1 to Figure 10 Shown is a high-temperature gas-cooled reactor main equipment support connection device provided in this embodiment. The entire structure of the connection device is divided into four parts according to the combination form. The upper part is the support assembly 1 directly connected with the main equipment cylindrical tank, and the middle part is It is a load-bearing seat cushion 2, and the lower part is a pre-embedded component 3 connected with the building wall of the nuclear power plant. The above three parts are connected by main bolt fasteners 4 to form a whole.
[0044] The support assembly 1 is fixedly installed on the first structure to be connected 104. In this embodiment, the first structure to be connected 104 is a cylindrical tank body, and the reactor core reactor is installed in the cylindrical tank body, and the weight is very heavy. Or when the temperature of the system changes, it will be moved back and forth by the therm...

The invention relates to the technical field of high-temperature gas cooled reactors, in particular to a high-temperature gas cooled reactor main equipment supporting and connecting device which comprises a supporting assembly fixedly installed on a first to-be-connected structure, a first connecting face is arranged on the supporting assembly, a main connecting hole is formed in the first connecting face, and a fastener is installed in the main connecting hole in a clearance fit mode; the pre-embedded assembly is fixedly installed on a second to-be-connected structure, a second connecting face is arranged on the pre-embedded assembly, the first connecting face and the second connecting face are arranged in parallel, and the fastener and the second connecting face are detachably installed; one end of the bearing seat cushion is fixedly mounted on the second connecting surface, and the other end is slidably clamped with the first connecting surface. Therefore, when the main equipment deforms, the expansion and shrinkage thermal stress transmitted to the connecting device can be released through the short-distance displacement of the connecting device. The connecting device can be effectively prevented from being broken when the main equipment deforms, the connecting stability of the connecting device is ensured, and the high-temperature gas cooled reactor can safely and stably run for a long time.
Description
technical field [0001] The invention relates to the technical field of high-temperature gas-cooled reactors, in particular to a supporting connection device for main equipment of high-temperature gas-cooled reactors. Background technique [0002] The design of the high-temperature gas-cooled reactor is different from that of the traditional pressurized water reactor. The main equipment mainly includes the pressure vessel and the steam generator, which are connected "side by side". Equipment) shell will have thermal expansion, so that it will expand and contract in the radial direction, resulting in a certain displacement. The main equipment is all fixed on the position of the designated area by the supporting cushion of the main equipment. The supporting cushion in the prior art is rigidly connected with the lug plate on the main equipment and the connecting plate on the supporting cushion by bolts, so as to Keep the main equipment level and fixed. During the working proce...
