旋启式止回阀最大开度及偏心距的分析计算

Analysis and Calculation of Biggest Opening and Eccentricty for Swing Check Valve

旋启式止回阀流阻系数受阀的最大开度的影响很大。而阀的最大开度不仅与流动状态有关,还与阀门结构及偏心距有关。本文通过分析计算,提出了增大阀门开度的一套新思想,对优化阀门设计,节约能量有重要意义。

The flow drag coefficient of the swing check valve is effected greatly by the biggest opening angle of the valve which is related not only to the flow condition but also to the valve structure and eccentricity. Some new idea is presented which is of importance to the valve design and saving energy.
