11. Leak off lines
11. 泄流管道
(1) The leak off control system shall be independent of the feedwater pump sequence control system and shall be based on two independent leak-off valves, each rated at a minimum of half the required leak-off quantity and each supplemented by a pressure reducing device and its own pipeline to the deaerator.
（1）泄流控制系统应独立于给水泵顺序控制系统，并应基于两个独立的泄漏阀门，每个阀门额定为要求泄漏量一半的最小量，每个阀门配备一个降压装置并带有连接到除氧器的管道。
(2) Both leak-off valves shall be automatically flow controlled from an approved flow measurement device, but each shall have its own measurement device pressure tapping and pressure switches.
（2）两个泄漏阀都应通过获得许可的流量测量装置进行自动流量控制，但是每个阀门都应该有其自己的测量装置压力测量点和压力开关。
(3) Each leak-off line and its associated equipment shall be identical in all respects, making their operating functions interchangeable.
（3）每个泄流管及其相关的设备应在所有方面均相同，使之运行功能能够互换。
Beijing Chinese Subtitling Translation Service Agency has translated many technical documents about Leak off lines.
华译网上海翻译公司曾经翻译过大量有关泄流管道的资料文件。
(4) Each leak-off valve shall be provided with test closure and opening facilities from a local control panel. For closing, the test button shall operate only as long as it is kept depressed. The proposed leak-off control scheme shall be stated.
(4)每个泄漏阀都应配备一个测试开关装置，能够通过就地控制面板进行控制。关闭时，测试按钮只有在被持续按下时才运行。应说明建议的泄漏控制方案。
(5) Each leak-off valve shall be pneumatically operated.
（5）每个泄漏阀应气动运行。
(6) The pressure switches associated with the leak-off valves shall be such that they can be set at different values so that one valve opens before the other. If the reduction in flow is sufficient to cause both valves to open, they shall both remain open until pump flow is increased and leak-off is no longer required. The valves shall remain closed when the pump is stationary.
（6）与泄漏阀有关的压力开关应保证能够在不同值设定，从而使一个阀门能够在另一个阀门之前打开。如果流量减少量足以造成两个阀门都打开，两个阀门应保持打开状态直到泵流量增加，不再需要漏泄为止。法门应在泵处于静止时保持关闭状态。
(7) Actuating fluid pressure drop shall induce the opening of a leak off valve.
（7）起动流体压力降应能够促使泄漏阀打开。
(8) After 1000 open/close operations, leak off valves leakage under pressure of 100 bar shall remain at a non measurable level..
（8）1000次开/关操作后，泄漏阀在100bar压力下的泄漏应保持在不可测量的水平。
