摘　　要：梭式止回阀作为管道非能动技术的重要组成部分,可以在无外加动力驱动下自动实现管道系统的安全保障作用,能有效降低事故的发生。研究了梭式止回阀阀芯位移磁电传感器阀体和阀芯永磁体的有限元模型建立的方法以及对永磁体进行了二维静态磁场分析。首先在ANSYS中建立阀体及永磁体的二维模型,然后对其定义材料属性、网格划分、施加边界条件,完成有限元模型的建立;然后对阀体及永磁体进行二维静态磁场分析,最终得出梭式止回阀阀芯位移磁电传感器的磁场分布及强度状态。通过ANSYS有限元仿真,验证了梭式止回阀阀芯位移磁电传感器磁路设计方案的可行性。Shuttle type check valve is an important part of piping inactive technology, which can automatically achieve the security of pipeline system without external driving force and reduce effectively the happening of the accidents. It studies the methods to establish the finite element model of the permanent magnet valve spool displacement magnetoelectric sensor valve body , core and the permanent magnet,as well as establishes the 2-D static magnetic field analysis of permanent magnet. Firstly, establishes the valve body and the 2-D model of permanent magnet in the ANSYS, and then to define the material properties, meshing, applying the boundary conditions, to complete the establishment of the finite element model; then the body and a permanent magnet is analyzed 2-D static magnetic field, finally gets the magnetic field distribution and strength of shuttle type check valve spool displacement magnetoelectric sensor. It is verified the feasibility of shuttle type check valve spool displacement magnetoelectric sensor circuit design by ANSYS finite element simulation.
