由摩擦力矩公式研究球阀设计及质量控制

Discussion on Ball Valve Design and Quality Control Based on Friction Torque Formula

针对球阀在出厂测试或使用中出现的异常状况,根据球体与阀座的摩擦力矩计算公式,对公式中涉及的零部件参数进行分析、计算、设计,讨论了核心零件机加工工艺,介绍了球阀设计的重点及过程质量控制点,以提高球阀的综合质量。

In view of the abnormal conditions of the ball valve in the factory test or use,according to the calculation formula of the friction torque between the ball and the valve seat,the parameters of the parts involved in the formula are analyzed,calculated,and designed,and the machining process of the core parts is discussed.In order to improve the overall quality of the ball valve,the key points of the ball valve design and the process quality control points are improved.
