- One, why is a small two-seater valve opening oscillation work easier? 为什么双座阀小开度工作时容易振荡？
- The vacuum valve opens to admit air. 真空阀开启以补充空气。
- The TGP's third-stage open channel closure is characterized by large closure discharge, large closure water-head, and large opening velocity. 摘要三峡工程三期截流具有流量大、落差大、龙口流速大等特点。
- When the coid is powered the valve opens (t< 1s). 当切断电流时，阀门迅速关闭。
- So the exhaust valve opens before BDC and closes after TDC. 因此排气门在下止点之前打开，在上止点之后关闭。
- Regeneration opportunity and regeneration valve opening of DPF are controlled by 80C196KB single chip microprocessor. 采用80C196KB控制柴油机微粒过滤器再生时机和再生调节阀开度。
- Locate percentage of valve opening on the bottom scale of Flow Characteristic Curve (Fig. 6). 从流量特性曲线（图6）的底部刻度找出阀门开启度百分比。
- The paper introduces the design of a practical valve opening detector which has the characteristics of simple structure and low cost. 设计了一种实用的阀门开度检测器,该检测器具有结构简单、成本低等特点。
- The quick-release valve of grill type can not only increase valve opening but also decrease distinctly the fullsize-opening height. 增大阀孔周边长可减小全开高度，条孔栅格式快开阀既可增大阀孔的开口率，又可使全开高度明显减小。
- Adjust valve opening manually or automatically，to change the resistance force of pump discharge pipline, and make the flowrate steady as expected. 手动或者自动调节控制阀开度，改变泵输出管线的阻力，使流量稳定在期望值。
- Flowing capability is big and the flow resistance is little. When the valve opening, the valve core is located inside ball cavity and the flow route is straight tube. 流通能力大、流阻小。这是因为开启后阀芯位于藏球室内,阀体流道呈直筒式。
- After initial installation, a discharge from the relief valve opening may occur due to inadequate initial flushing of pipe lines to eliminate dirt and pipe compounds. 在初始安装后，由于管线没有经过正确的初始冲刷，污垢和管道杂质没有消除干净，安全阀的开口可能发生排放。
- Speed Control Valves are available for controlling valve opening or closing speed with pneumatic actuators. 速度控制阀可以用来控制阀门气动执行器的开启或关闭速度。
- The failure of valve opening sensor would cause valve management of DEH system working confusedly,and result in large scale change of turbine power in the case of governing stage pressure loop idle. DEH系统中阀位传感器的故障会给阀门管理带来混乱，特别在调节级压力回路未投入的情况下会引起汽机功率的较大变化。
- If the pressure builds up excessively, the pressure valve opens to relieve the pressure. 如果油箱内压力过高，则压力阀开启，以降低压力。
- By applying black box theory inlet pressure, inlet subcooling, outlet pressure and valve opening are selected as influence factors to flow coefficient of electronic expansion valve (EEV). 根据黑箱理论提出将阀前压力、阀前过冷度、阀后压力和膨胀阀流通面积作为膨胀阀流量系数的影响参数。
- The valve opens for tank discharge when tank head pressure is greater than valve inlet pressure. 当容器水头压力大于阀门进口压力时，阀门开启进行容器排放。
- The intake and exhaust valves open at the proper time to let in air and fuel and to let out exhaust. 吸气阀门和排气阀门在正确的时间打开，以使空气和燃料进入，以及使废气排出。
