旋塞阀的系列化设计与有限元分析
摘 要 旋塞阀在流体控制系统中起着至关重要的作用,在石油和天然气领域以及水处理
和化学加工操作中具有广泛的应用。这些阀门的性能会因其效率和使用寿命而受到影响,因此
需要采用强大的设计方法来实现更好的操作可靠性。
本论文以旋塞阀的系列化设计与有限元分析为核心,系统探讨了旋塞阀的结构优化、模块
化开发及性能验证方法,为工业阀门的高效设计与可靠性提升提供了理论依据与实践参考。
在设计中,论文对阀体、压盖、旋塞等关键部件进行了详细的结构分析与公式推导,涵盖强度
校核、密封比压计算、热膨胀补偿等关键参数,并结合 SolidWorks 生成三维模型与标准化工程
图。通过系列化设计进行了参数化配置与模块化架构,实现了不同规格(DN/PN 等级)阀门的
零部件兼容性。采用有限元分析进一步验证了设计的可靠性。旋塞的静力学分析表明,最大应
力(285 MPa)低于材料许用应力(345 MPa),但需通过过渡圆角优化以降低局部应力集中;
扳手的非线性接触分析揭示了头部过渡区的屈服风险,并提出增厚结构与表面强化工艺的改进
方案。这些分析结果为系列化设计的参数调整提供了科学依据,实现了性能与成本的平衡。

Serialization design and finite element analysis of stopcock
Abstract Plug The globe valve plays a crucial role in fluid control systems and is widely
applied in the petroleum and natural gas sectors, as well as in water treatment and chemical processing
operations. The performance of these valves is affected by their efficiency and service life, thus
requiring powerful design methods to achieve better operational reliability.
This thesis focuses on the series design and finite element analysis of globe valves, systematically
exploring the structural optimization, modular development, and performance verification methods of
globe valves. It provides theoretical basis and practical references for the efficient design and reliability
improvement of industrial valves.
In the design, the paper conducts detailed structural analysis and formula derivation for key
components such as the valve body, bonnet, and plug, covering strength verification, sealing pressure
ratio calculation, thermal expansion compensation, etc. Key parameters are calculated, and three-
dimensional models and standardized engineering drawings are generated using SolidWorks. Through
series design, parametric configuration and modular architecture are implemented to achieve
component compatibility for valves of different specifications (DN/PN grades). The reliability of the
design is further verified through finite element analysis. The static stress analysis of the plug indicates
that the maximum stress (285 MPa) is lower than the allowable stress of the material (345 MPa), but
the transition fillet needs to be optimized to reduce local stress concentration; the nonlinear contact
analysis of the wrench reveals the risk of yield in the transition zone of the head, and improvement
schemes such as thickening the structure and surface strengthening process are proposed. These
analysis results provide scientific basis for parameter adjustment in series design and achieve a balance
between performance and cost.
