Bolt group with protection function for nuclear power

Abstract

The invention provides a bolt group with a protection function for nuclear power. The bolt group comprises a threaded rod, a circular cover used for protection is arranged at the lower end of the threaded rod, the threaded rod penetrates through the circular cover, a first hexagonal groove is formed in the lower side of the circular cover, a hexagonal nut is clamped in the first hexagonal groove, and the hexagonal nut is in threaded connection with the annular end of the threaded rod; and a folding pipe is arranged at the lower end of the circular cover, the end, away from the circular cover, of the folding pipe is fixedly connected with a disc, a first annular groove is formed in the annular inner wall of the upper side of the circular cover, and a clamping spring is assembled on the first annular groove. Compared with the prior art, the bolt group has the beneficial effects that the first hexagonal groove and the clamping spring can be used, the hexagonal nut is limited and installed in the circular cover, the threaded rod and the hexagonal nut can be protected through the circular cover, the folding pipe and the disc, the threaded rod and the hexagonal nut are effectively prevented from being corroded, use is convenient, and the service life is prolonged.

Description

technical field [0001] The invention relates to a bolt group with protection function for nuclear power, which belongs to the technical field of nuclear power construction. Background technique [0002] Both the fusion of light nuclei and the splitting of heavy nuclei can release energy, which are respectively called nuclear fusion energy and nuclear fission energy. During fusion or fission, a large amount of heat is released, and the energy is converted according to nuclear energy-mechanical energy-electric energy. This kind of electricity can be called For nuclear power, with the rapid development of modern science and technology, nuclear power technology has been widely used. In nuclear power construction, it is often necessary to use bolt groups to fasten the corresponding nuclear power equipment to the relevant carrier. In long-term use, it is easy to Oxidizing the bolts and nuts will damage the bolts and nuts, which will affect the service life. Therefore, it is necess...
