本文在对早期某试验装置上的直通式减压器的结构介绍及性能优缺点分析的基础上,提出了采用同轴式设计理念设计同轴式减压器,并对同轴式减压器的结构设计、工作原理、设计输入和设计输出作了介绍,最后对减压器出口的压力进行动态测试,测试结果表明该同轴式减压器的设计可以满足一定精度的节流要求。 Based on the introduction of structure and performance advantages and disadvantages of the straight-through pressure reducer on a certain early experimental device, the coaxial conical pressure reducer is proposed based on the coaxial design concept, and the coaxial pressure reducer The structure design, working principle, design input and design output are introduced. Finally, the pressure of the pressure reducer is dynamically tested. The test results show that the design of the coaxial pressure reducer can meet the requirements of throttling with certain accuracy.
