气阀是活塞式压缩机中非常重要的部分,它关系着压缩机的效率和使用的可靠性。气阀的结构型式很多,常用的有网状阀、环状阀、槽状阀和条状阀等。压缩机的气阀应满足下列要求:(1)适时的开启与关闭;(2)关闭时的气密性;(3)较小的气流阻力;(4)足够的强度和耐磨性;(5)较小的余隙容积。最近许多 Valve is a very important part of piston compressor, it is related to the compressor efficiency and reliability of use. Many types of valve structure, commonly used mesh valve, ring valve, groove valve and strip valve. The compressor air valve shall meet the following requirements: (1) timely opening and closing; (2) air tightness at closing; (3) less air flow resistance; (4) sufficient strength and abrasion resistance; 5) smaller clearance volume.
