Flow Control Valve Based on Claw-pole Magnetic Levitation Torque Motor

传统流量调节阀存在结构复杂、质量大、输出流量小等缺点,不适用于航空航天等特殊领域。设计了一种新型流量调节阀,该阀为旋转直驱式,具有输出流量大、结构简单、质量轻等优点。利用UG软件建立三维模型,介绍了该流量调节阀的工作原理。基于Workbench和Fluent软件,分别建立流量阀的强度校核模型和流体域模型,进行阀芯、阀套变形量仿真及稳态流场仿真。加工实验样机,进行流量调节阀的静态特性测试。结果表明:该流量调节阀总质量为375.5 g,当入口压力为4 MPa,出口压力为3.5 MPa时,最大输出流量为25.99 L/min,满足质量轻、输出流量大的使用需求。

Traditional flow control valves have disadvantages such as complex structure,large mass,and low output flow,and are not suitable for special fields such as aerospace.A new type of flow regulating valve has been designed,which is a rotary direct drive type and has the advantages of large output flow,simple structure,and light weight.Using UG software to create a 3 D model,the working principle of the flow control valve is introduced.Based on Workbench and Fluent software,strength verification models and fluid domain models for flow valves are established,and simulations of valve core and sleeve deformation and steady-state flow field are conducted.The experimental prototype is processed and the static characteristics of the flow control valve are tested.The results show that the total quality of this flow control valve is 375.5 g,when the inlet pressure is 4 MPa,and the outlet pressure is 3.5 MPa,the maximum outlet flow rate is 25.99 L/min,which meets the needs of light quality and large outlet flow rate.
