| 德国奥玛品牌 进口高温高压电站闸阀安装在水,汽管道上作为启闭装置用。 结构简述: 1、高温高压电站闸阀采用压力自紧式密封结构，弹性闸板，两端支管为焊接连。
2、阀座密封面采用钴基硬质合金等离子喷焊而成，耐磨、抗擦伤性能好。
阀瓣密封面经硬化氮化处理。
3、阀杆表面经抗蚀性氮化处理，有良好的抗腐蚀和抗擦伤性。
4、高温高压电站闸阀的开启和关闭由电动装置来控制，电动装置分别配有专用电机，减速器、转矩控制机构、现场操作机构、手,电动切换机构，除就地操作外还可进行远距离操作。可根据用户要求选配扬州电力设备修造厂引进西门子技术生产的2SA30系列、上海自动化仪表股份有限公司十一厂引进英国ROTORK生产的A系列、瑞基测控设备有限公司生产的RA系列电动头。
安装说明: 1、电动闸阀必须垂直安装，阀杆向上，介质流向可从任何一侧流入。
2、电动装置安装在环境温度为一20"C～+40℃，相对湿度≤80％无腐蚀，无****性气体环境中。
3、电动装置用于管道温度低于350"(：时，则采用半流体锂基润滑油(Q／sYl002—65) 用于管道温度高于350~(：时，则采用DIN492—2N一4钠基润滑脂进行润滑。 Germany Omar brands imported as a lifting device with high temperature and high pressure power station gate valves installed on water, steam pipes.
Structure outlined:
