本文对整体不可拆卸球形阀装配技术进行了全面的分析与研究。通过仙游球形阀的厂内装配,成功开发出了球形阀的轴端密封与U形密封装配技术、球形阀上下游组合密封装配技术以及整体结构球形阀的装配程序、过程检测程序技术。这些技术均代表着目前整体结构球形阀的最先进技术。正是这些先进技术的应用,确保了仙游4台球形阀一次装配试验成功。本文所开发的技术具有广泛的推广与借鉴意义。
In this paper, the overall non-removable ball valve assembly technology has been fully analyzed and studied. Through the in-plant assembly of Xianyou ball valve, the company has successfully developed the shaft seal and U-seal assembly technology of spherical valve, the combination seal assembly technology of the upstream and downstream of the ball valve, the assembly procedure of the ball valve of the whole structure, and the process detection procedure technology. These technologies represent the state-of-the-art of the current monolithic ball valves. It is these advanced technology applications, to ensure Xianyou 4 ball valve assembly test success. The technology developed in this paper has a wide range of promotion and reference.
