补充资料：溢流阀、顺序阀、减压阀的比较
溢流阀 | 减压阀 | 顺序阀 | ||
控制油路的特点 | 通过调整弹簧的压力控制进油路的压力，保证进口压力恒定，p2＝0 | 通过调整弹簧的压力控制出油口的压力，保证出口压力p2稳定 | 直控式－通过调定调压弹簧的压力控制进油路压力；夜控式－由单独油路控制压力 | |
出油口情况 | 出油口与油箱相连 | 出油口与减压回路相连 | 出油口与工作回路相连 | |
泄漏形式 | 内泄式 | 外泄式 | 内泄式 | |
进油口状态及压力值 | 常态 | 常闭（原始状态） | 常开（原始状态） | 常闭（原始状态） |
工作状态 | 进出油口相通，进油口压力为调整压力 | 进油口压力低于出油口压力，出油口压力稳定在调定值上 | 进出油口相通，进油口压力允许继续升高 | |
联接方式 | 并联 | 串联 | 实现顺序动作式串联作卸荷阀用时并联 | |
功用 | 定压、溢流或安全作用限压、稳压、保压 | 减压、稳压 | 不控制系统的压力，只利用系统的压力变化控制油路的通断 | |
进油腔压力p1控制阀芯移动 | 出油腔压力p2控制阀芯移动 | 进油腔压力p1控制阀芯移动 | ||
