摘要
本文介绍一种新型气体流量调节门——旋转扇形流量调节门的结构原理,调节特性,对比试验结果及其在通风机性能自动测试中的应用。试验结果表明,该调节门是一种较为理想的流量调节装置,完全适用于通风机性能测试。
In this paper, a new adjustable testing valve of rate of gas flow is introduced. Its structure principles, characteristics of adjusting, contrast experimental results and application in automatic performance testing of ventilators are also provided. The experimental results show that the new valve functions to well in testing the rate of gas flow that it can be applied to the performance testing of ventilators.
