These flow valves do not appear to close during SRU shutdown.Hazard is if the main shutoff valve is "stuck" , these valves may add another level of isolation.
这些流量阀在SRU停车期间看起来似乎没有关闭。如果主关闭阀卡住就有危险,这些阀有可能会增加另一程度的隔离。(不好理解)

你应该结合更多的上下文来看,前面说在SRU关闭的时候,这些阀不关,当主关闭阀卡住,这些阀中的物质流动就会有阻碍。不是太确定

这其实是关于 flow valve(流量阀)三方面的内容。

三方面内容分开如下:
1.潜在的故障模式:
These flow valves do not appear to close during SRU shutdown.
这些流量阀在SRU停车期间看起来似乎没有关闭。

2.潜在的影响/危害:
Hazard is if the main shutoff valve is "stuck" , these valves may add another level of isolation.
如果主关闭阀卡住就有危险,这些阀有可能会增加另一程度的隔离。

3.建议措施:
Suggest to have cutoff valves and flow valves close during SRU shutdown. Suggest adding solenoids on these valves, driven by the shutdown system.
建议在SRU停车期间关掉截止阀和流量阀。建议在这些阀门上增设电磁阀,由停车系统驱动。

没有更多的上下文。只能从专业上理解喽。有没有更好的理解?

这些流量 ...

the word isolation is used in two ways (commonly):
1. to isolate a problem
2. to make that area to be isolated; as in case of fire, we isolate the burning area from the other structures.
suggest you read the context and make some good sense out of it.

根据提供的上下文,我的理解如下:
该装置的系统切断有一个主要的切断阀shutoff valve,
其次还有若干流量阀,正常的情况下,当系统被切断后(通过SHUTOFF VALVE),
系统应该无流量,但是一旦切断阀失效时,流量阀的断开就变的非常重要。
可是在在SHUTOFF VALVE STUCKED的情况下,流量阀又没有关闭,就会造成潜在
的危害。
因此又要给流量阀加一层保护,这很容易,只要在其上游加一个电磁阀即可。
该电磁阀关闭时,就会隔离流量阀的工作,不管该流量阀是否开启。

如果有示意图或管路图,你可能更好的理解。

I would suggest "jia duo yiceng geli", similar to "jia yiceng baohu" as in hansonstep's #5 above.
