摘要：蝶阀又叫翻板阀，是安装于旋转轴上的金属蝶板。阀门关闭时阀板旋转完全挡住通道；阀门全开后阀板旋转四分之一转，允许流体几乎不受限制的流通。通过手柄在90°内转动以提供一个完整的关闭或打开阀门的过程。如果阀体轴孔有较好的同轴精度，则可以降低操作扭矩，减少磨损，增加密封性能。探讨轴线与轴线法、公共轴线法、直线度法、模拟装配轴等检测同轴度方法，满足产品检测和交货需要。

Abstract：A butterfly valve is from a family of valves called quarter-turn valves. The "butterfly" is a metal disc mounted on a shaft. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. A 90° rotation of the handle provides a complete closure or opening of the Valve. If butterfly valve body have Preferably coaxial, it can reduce operation torque, reduce wear and increase the sealing performance. This paper discusses the method of the axis with the axis, the common axis, straightness, simulate assembly of coaxial bearing bores and so on, products inspection and delivery to meet the requirements.
