拥有较长的使用寿命和免维修期，将依赖以下几个因素:正常的工作条件、保持和谐的温度/压力比，以及合理的腐蚀数据
球阀在关闭状态下，阀体内部依旧存在受压流体
维修前，解除管线压力并使阀门处于打开位置
维修前，断开电源或气源
维修前，将执行机构与支架脱离

必须先查明球阀上、下游管道确已卸除压力后，才能进行拆卸分解操作
分解及再装配时必须小心防止损伤零件的密封面，特别是非金属零件，取出O 型圈时宜使用专用工具
装配时法兰上的螺栓必须对称、逐步、均匀地拧紧
清洗剂应与球阀中的橡胶件、塑料件、金属件及工作介质(例如燃气)等均相容。工作介质为燃气时，可用汽油(GB484-89)清洗金属零件。非金属零件用纯净水或酒精清洗
