double valve meaning in Chinese
双活
双联阀
Examples
- This trap adopts parallel double valve seats , thus the capacity of water discharge is enlarged . it can satisfythe working condition of discharge frozen water in large quantity
该阀采用平行双阀府，因而增大了排水能力，能满足大量排除凝结水的工况。 - Secondly , with commercial cfd code - fluent , three dimensions turbulence flow fields of fixed - valve trays with single valve and double valves were computeed by means of rng k - e turbulence model in the system of lagrange
同时，采用商业计算流体力学软件fluent软件包对固定阀进行几何建模和网格划分，采用rng -湍流模型，计算了固定阀单阀和双阀塔板的二维和三维流场。 - By comparing the dry plate pressures drop and distributions of velocities simulated on single valve with those of double valves , it was found that there was intense turbulence in the flow fields around fixed - valve , there were eddy areas between valve side orifices and tray wall , there were eddies above the valves too , these led to the complex behaviors of gas perforating valve , these had a great effect on the gas - liquid mass transfer process . at the same time , in order to prevent the disadvantageous effect of gas between one valve with another on the gas - liquid mass transfer , it was very effective to change the fields of gas perforating valve by folding the edges of valve
通过对数值模拟得出的单阀和双阀塔板的干板压降及流场速度分布分析对比后发现，固定阀周围流场存在较强的湍动，阀侧孔与塔板壁面区域以及阀体的上方空间存在明显的涡流区，使气体穿阀后的行为变得复杂，并对气液传质过程产生重大影响；模拟结果表明，为防止和削弱固定阀间的对冲造成的“死区”对传质带来的不利影响，通过折边来改变气体的气路是非常有效的，模拟值与实验值基本得到吻合。
