先确定泄漏位置和条件 Identify location and conditions
记录是接通气水后立即泄漏、工作时泄漏还是停机后残余泄漏，并观察软管、接头、阀体和外部连接位置。 Record whether leakage starts on supply connection, during operation or after shutdown. Observe hoses, fittings, valve bodies and external joints.
外部检查不等于带压拆卸 External checks do not mean pressurized dismantling
可在安全状态下检查松动、破损和明显磨损；任何拆卸前都必须停机、关闭气水源并确认完全卸压。 Check looseness, damage and visible wear only in a safe state. Before any dismantling, stop, isolate air/water sources and verify complete depressurization.
密封和内部通道按型号检修 Service seals and internal passages by model
持续泄漏或内部串流应由专业人员依据当前型号资料处理，不用通用经验替代正式尺寸和装配要求。 Persistent leaks or internal cross-flow require qualified service using current model documentation, not general assumptions about dimensions or assembly.
