摘要
在研究小修作业用双闸板防喷器结构特征的基础上,提出了双闸板防喷器壳体结构设计的基本原则,并设计了一种新型壳体结构。为验证设计的合理性,对所设计的壳体进行了有限元分析,提出了建立1/4模型进行有限分析的建模方法,利用该模型,分析了法兰与壳体联接部分过渡圆角对壳体应力的影响,得到圆角半径在9-12 mm之间为宜。经70 MPa静水压试验分析结果表明,壳体强度满足API规范要求。
Based on the structure of double ram BOP used for workover, the basic principle of the BOP body design is presented, and a new structure is designed. The structure is analyzed using the finite element method to validate its rationality. Its quarter element model is established. The fillet between the flange and the body affects its stress greatly and its radius should be in 9～12mm; The results of static hydraulic tests show that the body can endure 70MPa pressure and these conclusions have important meaning for BOP body design.
