STTR PHASE I: Integration of Electromagnetic Actuation Using VOST Design

这个小型企业技术转让(STTR)第一阶段项目将研究使用电磁力驱动文丘里偏置技术VOST(TM)阀的可行性。传统的阀门执行机构杆和填料是有害排放物的重要来源，并为流体污染提供了机会。将在该项目中开发的执行器创新将消除阀杆和填料，从而消除这种排放源。VOST(TM)轴向设计提供了完成这一任务的平台，但前提是电磁驱动。这项研究将利用设计建模(数值模型)和执行器测试来确定配置电磁执行器所需的扭矩、速度和位移特性。首先，工作计划将评估VOST(TM)设计的扭矩、速度和旋转位移规格。获得的信息将用于对三种可能的执行器配置进行排序。最有希望的配置将被制作成原型并进行性能测试。此外，还将使用组件成本、复杂性和适用性来评估此配置的商业可行性。预计所选的电磁配置将满足所需的运行参数。采用这种驱动概念的VOST(TM)设计的阀门将消除排放源。如果成功，这项研究将产生一种电磁执行器配置，可以促进密封阀的工作。开发的致动器概念可以扩展到任何需要180度或更小的轴向旋转的应用。这将适用于阀门以外的控制系统。

This Small Business Technology Transfer (STTR) Phase I project will investigate the feasibility of using electromagnetic force to actuate a Venturi Off-Set Technology VOST(TM) valve. Traditional valve actuator stems and packing are significant sources of harmful emissions and provide opportunities for fluid contamination. The actuator innovation to be developed in this project would eliminate stems and packing, thereby eliminating this source of emissions. The VOST(TM) axial design provides the platform to accomplish this task, but only if actuated electromagnetically. This investigation will utilize design modeling (numerical models) and actuator testing to determine torque, speed and displacement properties needed to configure an electromagnetic actuator. First the work plan will evaluate the VOST(TM) design for torque, speed and rotational displacement specifications. Information obtained will be used to rank three potential actuator configurations. The most promising configuration will be prototyped and tested for performance. In addition, commercial feasibility of this configuration will be assessed using component cost, complexity, and serviceability. It is anticipated that the selected electromagnetic configuration will meet desired operational parameters. VOST(TM) designed valves incorporating this actuation concept will eliminate sources of emissions. If successful, the research will result in an electromagnetic actuator configuration that can facilitate a hermetically sealed valve. The actuator concepts developed can be extended to any application requiring an axial rotation of 180 degrees or less. This will apply to control systems beyond valves.
