您要查找的是不是：
- Should flow rate decrease rapidly a pressure controlled surge pilot closes the valve to prevent downstream pressure buildup. 当流速迅速减少时，压力控制的补偿引导装置就关闭阀门，防止下有压力累积。
- To avoid this discharge, install a spring-loaded rubber seated check valve ahead of the backflow assembly to "lock-in" the downstream pressure. 为了避免这类排放，要在防回流阀总成前安装一个弹簧负载橡胶阀座止回阀来"锁定"下游压力。
- To avoid this discharge, install a spring-loaded check valve ahead of the backflow assembly to "lock-in" the downstream pressure. 为了避免这种排放，应该在防回流阀总成前面安装一个弹簧负载止回阀来“锁定”下游压力。
- The GIPS/GDPS Series of Automatic Shut-off Valves are safety devices designed to stop the flow of gas when the downstream pressure of the valve reaches a value larger than and/or smaller than the preset operating limit. 升压感应关断型?与GDPS?降压感应关断型?系列自动关断阀为安全设备，设计当此阀下游压力达到大于或?和?小于预定操作限度的压力值时，来中断瓦斯流动。

- Loss of pressure had not registered on the dials. 刻度盘未记录压力下降。
- Air pressure forces the water through the pipe. 空气压力使水通过管道。
- What's the atmospheric pressure today? 今天的气压怎么样？
- The water pressure may need adjusting. 水压可能需要调整。
- Pressure is force per unit area. 压力就是电单位面积上的力。
- He drop out because of the pressure. 由于校规很严，所以他退学了。
