1.中止;堵塞;中断;关闭器
1.a device, usually a valve, that shuts something off
2.an interruption or stoppage, e.g. in flow or supply
1.It shall be a complete assembly including tight-closing resilient seated shutoff valves, test cocks, and a strainer is recommended.
这种总成应该是完整的，包括紧密关闭弹性阀座关闭阀（闸阀），测试旋塞，以及建议配置的一个过滤器。
2.Microbe have been applied to preparing polymer (Xanthan), MEOR, water-shutoff, processing polluted water, treating environment pollution.
微生物工程可用于制取生物聚合物、微生物提高采收率技术（MEOR）、处理污水、治理环境污染等；
3.The shutoff valve with the test cock is to be mounted on the inlet side of the backflow preventer.
带测试旋塞的关闭阀应该安装在防回流阀的进口侧。
4.This feature "block and bleed" may be important as its use can show whether the valves are providing liquid-tight shutoff of fluid flow.
由于管道闸阀可以观察关阀时对流体的密封性能，这种“开、关”特性是很重要的。
5.Many bronze valves offer a Y-pattern body with an angle seat for improved performance. Resilient seating preferred for tighter shutoff.
许多青铜阀门为了改进性能，采用角式阀座的Y形阀体。如果需要更紧密的关闭，就需要采用弹性阀座。
6.A shutoff gate is associated with each connecting trough and movable between an open position and a closed position.
阻断闸板与每条连接槽相关联且可在打开位置与关闭位置之间移动。
7.At the same time comparative experiments of its water shutoff performance also be conducted with other types of temporary plugging agent.
同时还将暂堵剂与其它类型的暂堵剂进行了堵水性能的对比实验。
8.Therefore, the water shutoff profile increases the workload of each year, more difficult work, and reduce the potential for increasing oil.
因此，堵水调剖的工作量逐年增大，工作难度增加，而增油潜力降低。
9.Application Industrial gas system applications for safety shutoff, pressure control, or differential-pressure control.
应用工业气体安全关断，压力控制或压差控制系统应用。
10.When extremely tight shutoff is required, globe and check valves are supplied with Neoflon, PTFE or other soft inserts.
如果需要紧密关闭，球阀截止阀和止回阀都会配置四氟乙烯、PTFE或其它软镶嵌件。
