| 2. | Quick closing valves , water hammer or supply pressure fluctuations can cause intermittent discharge
迅速关闭阀门，水锤或供应压力波动可能导致间歇性排放。 |
| 3. | Hinge ? designed to withstand the shock load of quick closing to insure longer life and continued shut - off
铰链-能够承受迅速关闭而产生的冲击负载，确保使用寿命更长和连续关闭。 |
| 4. | After discharge the moment made by heavy hammer and rocker will drive disc close quickly to realize locking air
一旦积灰卸去后，重锤与摇杆产生的力矩使阀板迅速关闭，实现锁气。 |
| 5. | Our rugged hinge pin / hinge and disc construction is designed to withstand the shock of quick closing and provides years of service
我们坚固的铰链销/铰链和阀瓣结构适用于承受迅速关闭所产生的冲击，延长了使用寿命。 |
| 6. | This short - arc coupled with the low pendulum effect achieved by pivoting the disc through a point near its center of gravity assures rapid closure
绕轴旋转的阀瓣的重力中心距轴心较短，因此这种短弧的钟摆效应也比较小，从而确保能够迅速关闭。 |
| 7. | Tilting disc check valves have to close rapidly since the disc has a shorter distance to travel and therefore arrives at the seat faster . . . minimizing a slam
翻转式阀瓣止回阀能够迅速关闭，这是由于阀瓣的运行距离很短，因此能够迅速到达阀座位置，从而最大限度减小撞击现象。 |
| 8. | Then a tentative plan came to our brains , is it possible for us to assure guard cells to open when water supply is enough , and close rapidly when plants come across drought stress by regulating expressional pattern of genes
我们的设想是：当水分供应充足时，气孔尽最大限度开放，吸收co _ 2 ，增加光合产量；当干旱来临时，气孔迅速关闭，减少水分丧失，提高作物的水分高效利用率。 |
