一、前言气阀是压缩机的心脏、其设计好坏直接影响压缩机的可靠性及经济性. 压缩机的气阀有各种结构。应用较多的是环状阀、网状阀、碟阀、槽阀,直流阀、条片阀及舌簧阀。微型压缩机技术的发展,要求降低比功率、减小噪声、提高气阀寿命。这样舌簧阀就迅速代替了环状阀。舌簧阀阀片是用弹性薄钢片制成。它既是密封元件,又是弹性元件,因而结构简单,同时还具有气体流动阻力小、余隙容积小、阀片质量轻、易于启闭的优点,对于降低压缩机的比功率起着决定性作用。
First, the preface Valve is the heart of the compressor, the design of a direct impact on compressor reliability and economy.Compressor valve has a variety of structures. More applications are ring valve, mesh valve, butterfly valve, slot valve, DC valve, strip valve and reed valve. The development of miniature compressor technology, requiring lower specific power, reduce noise and improve valve life. This reed valve quickly replaced the ring valve. Reed valve The valve is made of flexible steel sheet. It is both a sealing element and an elastic element. Therefore, the utility model has the advantages of simple structure, small gas flow resistance, small clearance volume, light weight of the valve plate and easy opening and closing, which plays a decisive role in reducing the specific power of the compressor.
