电动阀的日常维护管理电动阀通常由电动执行机构和阀门连接起来，经过安装调试后成为电动阀。
电动阀使用电能作为动力来接通电动执行机构驱动阀门，实现阀门的开关、调
节动作。从而达到对管道介质的开关或是调节目的。 电磁阀是电动阀的一
个种类；是利用电磁线圈产生的磁场来拉动阀芯，从而改变阀体的通断，线圈
断电，阀芯就依靠弹簧的压力退回。
1、电动阀门应存干燥通风的室内，通路两端须堵塞。
2、长期存放的电动阀门应定期检查，清除污物，并在加工面上涂防锈油。
3、安装后，应定期进行检查，主要检查项目：
（1）密封面磨损情况。
（2）阀杆和阀杆螺母的梯形螺纹磨损情况。
（3）填料是否过时失效，如有损坏应及时更换。
（4）电动阀门检修装配后，应进行密封性能试验。
运行中的电动阀门，各种阀件应齐全、完好。法兰和支架上的螺栓不可缺少，
螺纹应完好无损，不允许有松动现象。手轮上的紧固螺母，如发现松动应及时
拧紧，以免磨损连接处或丢失手轮和铭牌。手轮如有丢失，不允许用活扳手代
替，应及时配齐。填料压盖不允许歪斜或无预紧间隙。对容易受到雨雪、灰尘
、风沙等污物沾染的环境中的电动阀门，其阀杆要安装保护罩。电动阀门上的
标尺应保持完整、准确、清晰。电动阀门的铅封、盖帽、气动附件等应齐全完
好。保温夹套应无凹陷、裂纹。 不允许在运行中的电动阀门上敲打、站人
或支承重物；特别是非金属电动阀门和铸铁电动阀门，更要禁止。
