| Abstract: | The seal pair interference computation principle of the three eccentric butterfly valve is analyzed; the effect of its radial eccentricity which is that the distance of its rotation center relative to the pipeline center, the axis eccentricity which is that its rotation center relative to the butterfly shutter , the angle eccentricity which is that the angle of the cone axis relative to the pipeline center and the half cone's angle on the seal pair's interference of the tri eccentric butterfly valve are calated calculated; and their reasonable selected range is given. |
