如果流体流速压力无法将阀门支撑在一个较大的开启度并保持在稳定的开启位置，则阀瓣和相关的运动部件可能会处于一种持续振动的状态。
The disc and associated moving parts may be in a constant state of movement if the velocity pressure is not sufficient to hold the valve in a wide open and stable position.
即使在大流速下，也能够确保阀瓣和阀座的精确对准。
Assures perfect alignment of disc and seat even at large flow velocities.
随着产生蒸汽的压力逐渐增大，排出蒸汽的流速加快，将阀芯上推堵住排气通道。
Following the gradual enlargement of steam generation pressure, the flow velocity of exhausting steam is accelerated; then, the valve core is pushed upwards to block an air exhaust passage.
结果表明：适当降低流过蓄热体的气体流速，缩短四通换向阀的切换时间，可降低烟气的出口温度，提高系统的余热回收率。
Result shows that decreasing fluid rate and shortening switching time can decrease the temperature of the exhaust gas and increase the recovery rate of waste heat.
所述蒸气流速取决于所述气化器的温度及位于所述气化器与所述真空室之间的机械节流阀的流导的设定值二者。
The vapor flow rate is determined by both the temperature of the vaporizer and the setting of the conductance of the mechanical throttle valve located between the vaporizer and the vacuum chamber.
试验还利用荧光粒子进行了阀隙流场测量，得到了层次清晰的抛物线状阀隙流速分布和阀隙区域的速度脉动分布。
With the results, the general features of the flow are analyzed and summarized from the perspectives of velocity profiles, vorticity distributions and trend charts of velocity.
进液阀芯和阀座，由于开启关闭比较频繁，液体流速高，密封很快就会失效。
Inlet valve and seat, due to open and close more frequently, the liquid flow rate is high, sealing will soon expire.
