| titleOfInvention | Fixed-pitch threaded rod looseness preventing structure of pressurized water reactor nuclear power plant vapor generator |
| abstract | The utility model belongs to a vapor generator design technology, and particularly discloses a fixed-pitch threaded rod looseness preventing structure of a pressurized water reactor nuclear power plant vapor generator. The fixed-pitch threaded rod looseness preventing structure comprises a pipe locating plate and a plurality of fixed-pitch threaded rods. Arc-shaped grooves are machined in the fixed-pitch threaded rods. Rectangular sunk holes are machined in the pipe locating plate. Locking gaskets are arranged inside the rectangular sunk holes. The lower fixed-pitch threaded rod is fixedly connected with the upper fixed-pitch threaded rod through threads. Due to the fact that the arc-shaped grooves are machined in the fixed-pitch thread rods, when the fixed-pitch threaded rods and a pipe bearing plate are installed, the adopted locking gaskets can be compressed inside the arc-shaped grooves, the fixed-pitch threaded rods cannot be loosened or disengaged inside the pipe bearing plate and looseness and disengagement are prevented. Due to the fact that an end portion nut is installed on the upmost fixed-pitch threaded rod and arc-shaped grooves and tooth-shaped grooves are formed in the outer side of the nut, the upmost fixed-pitch threaded rod can be prevented from being loosened and disengaged, and meanwhile, due to the fact that the tooth-shaped grooves are machined, the end portion nut is also convenient to screw. |
