AUMA 进口法兰闸阀（德国奥玛AUMA）

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:
1, high temperature high pressure power station gate valve with pressure from the tight-sealing structure, flexible gate, both ends of the manifold even welding.
Seat sealing surface cobalt-based alloy plasma spray welding made ​​of wear-resistant, anti-abrasion performance.
Valve sealing surface hardening nitriding treatment.
3, stem surface nitriding process of corrosion resistance, good corrosion resistance and scratch resistance.
4, the high temperature high pressure station the gate valve opening and closing is controlled by the electric device, the electrical device equipped with dedicated motor, speed reducer, torque control means, live operating mechanism, the hand, the electric switch mechanism, except local operation can also be remote operation. A Series of the British ROTORK production can be introduced 2SA30 series introduce Siemens technology to produce according to the user requirements optional power equipment repair plant in Yangzhou, Shanghai Automation Instrumentation Co., Ltd. eleven plant Rickey monitoring and control equipment Limited the RA series production electric head.
