阀门设计方法 在负压和过压情况下,由吸、排气阀分别产生的能量损失分别示于图5中,其中最主要的是吸、排气阀的逆流损失。故从这两方面着手,对阀门进行最佳设计,从而对改善压缩机特性提供了最多的机会。阀门设计工作由研究人员承担,有关这方面的参考资料可见文献〔3〕。下面介绍阀门设计工作中的一些实际经验,以供开始从事压缩机设计的工程技术人员参考。 （1）阀门的设置、重叠量和硬度等特
Valve design method In the case of negative pressure and over-pressure, respectively, by the suction, exhaust valve, respectively, the energy loss are shown in Figure 5, of which the most important is the suction and exhaust valve of the countercurrent loss. Therefore, from these two aspects, the best design of the valve, which provides the most opportunities to improve the compressor characteristics. Valve design work by the researchers, reference information on this can be found in the literature [3]. Here are some of the valve design experience in practical work, for beginners engaged in compressor design engineers and technicians reference. (1) valve settings, overlap and hardness and other special
