A study on the flow regulation characteristics of a swirlmeter regulator
摘要
Abstract
The characteristics of flow measurement and regulation of a swirlmeter regulator, which combined a swirlmeter and a control valve, were investigated experimentally. The output characteristics of the swirlmeter were examined in the cases with and without a conical valve upstream of it. It was observed that, the fluctuating frequency of the dynamic pressure signals, I. E. The precession frequency of swirls, presented a perfect linear relationship with flow rate, whatever there was a conical valve upstream of the swirlmeter or not. For a same flow rate, the variation of the precession frequency due to the existence of the valve was less than 5%. These results indicate that the swirlmeter can work normally in this combined regulator. In the experiments of the flow regulation characteristics, flow rate were measured with inlet pressures varying from 0. 11 to 0. 23 Mpa and valve core moving in a range of 0 to 8 mm away from the original position. The results show that, for a constant inlet pressure, the flow rate increases linearly with the increasing of the valve opening. As the inlet pressure increases, the flow rate also increases, and vice versa.关键词
