为了研究矿用阀试验台中的高压大流通量截止阀的特性,采用了Solid Works中Flo Xpress模块对其进行了通道流场分析,得出了内部流线形状及最大流速等参数,通过修改阀开口角度及阀的通径尺寸,对其进行了详细的研究,结果显示,通径为准200 mm的球型截止阀最大流速出现在开口10°左右时,在开口大于60°后迅速衰减。最大流速与阀的通径相关性较小,考虑到流通量为流速在阀横截面的积分,可以认为其与阀的通径成正比关系。
In order to study the characteristics of high pressure and large flow-through shut-off valve in mine valve test bench, Solid Works Flo Xpress module was used to analyze the flow field of the valve. The internal flowline shape and the maximum flow velocity were obtained. Opening angle and valve size of the valve, a detailed study of the results showed that the diameter of 200 mm ball valve maximum flow rate appears in the opening of about 10 °, the opening is greater than 60 ° after the rapid decay. The maximum flow velocity is less dependent on the valve diameter. Considering that the flow rate is the integral of the flow velocity across the valve cross section, it can be assumed that it is proportional to the valve diameter.
