空气阀水锤防护特性的主要影响参数分析及优化（Analysis and Optimization of Main Influencing Parameters for Water-hammer Prevention Characteristic of Air Valves）
空气阀 水锤防护 影响因素
2009/8/11
对空气阀水锤防护特性的主要影响因素进行了试验分析。结果表明：在合理位置安装合适进排气孔口径的空气阀可有效防止因水柱分离再弥合而导致的巨大水锤升压，但空气阀的防护效果受安装位置和进排气孔口径的影响较大；口径过大，在排气过程中会产生较大的水锤升压，口径过小则可能因进气量和进气速度不够而达不到水锤防护的效果，实际应用中应对进、排气孔口径进行优化或采用“快进慢出”的结构形式；对本试验装置，空气阀应安装在首...
