摘　　要：本文分析了打包机的锁门机构回路中,双向液控单向阀被锁死的原因。当液控单向阀的开启比大于液压缸的速比时,才有可能打开液控单向阀。所以选用液控单向阀应考虑与系统的压力及被锁紧的最大负载之间是否匹配,以避免液控单向阀被锁死。The paper introduces the reason that the pilot controlled check value is locked in locking mechanism loop of baler. Only just the unlock ratio of pilot controlled check value is greater than the velocity ratio of oil cylinder, it may open up pilot controlled check value. To avoid pilot controlled check value of being locked, you should think that if it matches systemic pressure and maximum load of being locked.

关 键 词：液控单向阀 开启比 速比 锁死
