一、概述我国目前使用的客货车用三通阀主要是K.P.L型的,三通阀的结构均为鞲鞴和滑阀式的,为了保证三通阀的作用性能良好,规定滑阀与座间接触表面的光洁度为??10.并且组装后要求具有较好的气密性,因而在组装时除必须规定合理的操作工艺方法外,采用符合于研磨要求的研磨膏对提高研磨表面质量和提高研磨效率均有很重要的意义.但是在实际生产和检修中一直到现在尚未完全解决,使三通阀研磨质量的提高受到一定的阻碍,从研磨膏的使用情况来
First, an overview of China’s current use of three-way vans for passenger cars are mainly KPL-type, three-way valve structure are 鞲 鞴 and slide valve type, in order to ensure the good performance of three-way valve, the provisions of the valve and seat The contact surface finish is ?? 10. And after the assembly requires good air tightness, and therefore in addition to the assembly process must be provided in a reasonable manner, the use of grinding in line with the requirements of the grinding paste to improve the quality of the grinding surface and Improve the grinding efficiency are of great significance.But in the actual production and maintenance has not been fully resolved so that the improvement of three-way valve grinding quality is subject to certain obstacles, from the use of abrasive paste to
