体材质的不同等原因，造成的因选型错误导致电磁阀密封面损坏。四：电磁阀产品常与酸类等具有腐蚀性的介质接触，在长时间的工作状态下，由于腐蚀性介质的接触，造成电磁阀内部密封面的腐蚀。电化学侵蚀，密封面互相接触、密封面与封闭体和阀体的接触以及介质的浓度差、氧浓差等原因，都会产生电位差，发生电化学侵蚀，致使阳极一方的密封面被侵蚀。人为原因主要是由于安装不当，以及在使用的过程中不当的操作，后期的维护没有做好等问题。用户在检查电磁阀密封面故障问题的时候，可以先从正常的磨损考虑，其次是工作环境和介质属性是否满足电磁阀工作条件，最后检查其他例如电磁阀型号选择问题密封面质量问题等。调节阀的常见故障有哪些？在自动阀门行业中，自动化工业在处理阀门定位器气源接头漏
