| Abstract: | This paper analyzes the calculation method and formula of orifice area of double triangular groove and U shaped groove assembled shape orifice. By establishing the calculating program in MATLAB, and using polynomial segmentation to fit the combination valve orifice area curve, we obtain the expressions of valve orifice area A（x） and area gradient W（x）. |
