为提高压力容器螺栓法兰的紧固效果，对液压扳手和握持套筒的结构进行了改进，优化了握持套筒，并设计了一款新型固定扳手；对螺栓法兰紧固操作的液压扳手和握持套筒的配合使用进行了详细介绍并进行了对比，对握持套筒存在的问题进行了改进；运用ANSYS对新型固定扳手进行了静力学结构分析。结果表明，该结构优化可有效提高压力容器法兰螺栓的紧固效果。

In order to improve the fastening effect of the bolt flange of pressure vessel, the structure of the hydraulic wrench and the holding sleeve was improved, and the holding sleeve was optimized, and a new type of fixed wrench was designed. The paper introduced and compared the joint use of hydraulic wrench and holding sleeve in bolt flange fastening operation, improved the structure of the holding sleeve, and analyzed the static structure of the new type fixed wrench by ANSYS. The results show that the structure optimization can effectively improve the fastening effect of flange bolts of pressure vessel.
