摘要
介绍了特殊螺纹接头发展历史及现状,国内外主要生产供应商生产的特殊螺纹接头类型及其特点。对特殊螺纹接头研究的重点和难点如:金属接触的密封结构及过盈量控制、螺纹受力优化和螺纹抗黏扣技术等进行了实例专利分析。指出了目前我国在研究特殊螺纹接头过程中存在的主要问题,为特殊螺纹接头的国产化提出了一些建议。
This article introduced the development history of the premium connections and the main manufacturers of these product and their characteristics. Moreover, the important aspects are analyzed by the examples of patent such as seal structure and wring of the couple mental contact, thread force optimization, and anti-galling technology. Meanwhile, this article pointed out the main problems on premium connections research in China and some advice is given about domestic research of premium connections in this paper.
