翻译一段关于系统中阀门动作的科技英语

• The SGS provides a power-operated relief valve block valve upstream of the steam generator power-operated relief valve in each steam line. The power-operated relief valve block valve is qualified as an active valve, with the safety-related functions of transfer-close and maintain-close, to perform the outside containment isolation function for the power-operated relief valve inlet line. The basis for this is to provide isolation when required during a steamline break, while still providing the capability for steam relief through the power-operated relief valve for those transients and accidents where lifting of the steam safety valves can be prevented by power-operated relief valve operation.
SGS在每一个蒸汽管线上有一个电动减压阀堵塞阀蒸发器逆流电动减压阀？语义不通。
基础是当蒸汽管道破裂时根据需要提供隔离，当瞬态及事故条件下，通过电动减压阀实现蒸汽减压的能力可以继续时，在蒸汽压力增高的地方，安全阀可以被电动减压阀禁止操作。 我自己翻译的都看不明白。高人帮助翻译一下。

重新提交，这一句话的意思是什么

Answer 1

SGS 提供蒸气的产生器力量操作的减轻每个蒸气的线活瓣的力量操作的减轻活瓣块活瓣上行数据流。 力量操作的减轻活瓣块活瓣是有资格的如一个活跃的活瓣,藉由移动- 结束和维持-结束的安全- 相关的的功能, 为力量操作的减轻活瓣插入物线运行外面的包含隔绝功能。当在 steamline 休息期间需要的时候 , 基础为这要提供隔绝, 当仍然对那些暂态和蒸气的安全活瓣的升高可能被力量操作的减轻活瓣操作避免的偶然事故经过力量操作的减轻活瓣为蒸气的减轻提供能力的时候。
