一、前 言 气阀对于活塞式压缩机的重要作用是众所周知的。它的性能对压缩机的工作可靠性、经济性都有很大影响。获得气阀的长寿命和高效率是设计人员孜孜以求的目标。近年来,随着对气阀运动规律的研究和认识,使气阀设计工作有了可靠的理论基础。当然,讨论气阀的寿命问题,也决离不开其运动零件阀片和阀弹簧的寿命问题。气阀弹簧除应满足气阀运动规律对 First, the foreword Valve for piston compressor important role is well known. Its performance on the reliability of the compressor, the economy has a great impact. Obtaining the valve’s long life and high efficiency is the diligent goal of the designer. In recent years, with the research and understanding of the valve movement law, the valve design has a reliable theoretical basis. Of course, discuss the life of the valve problem, but also inseparable from the life of its valve parts and valve spring life issues. In addition to valve spring should meet the valve movement law
