water hydraulic valve meaning in Chinese
水压阀
Examples
- Here are three parts in this thesis : building steady state model and transient model for water hydraulic valves . research on the property of flow field inside water hydraulic valves . analysis of the force on water hydraulic valves
论文主要包含三部分的内容：水压阀稳态模型和瞬态模型的建立；水压阀内流场过流特性的研究；作用于水压阀阀芯及阀体上的力特性分析。 - Because the operation in water hydraulic valves is controlled by flow fluid and the pressure drop results from energy loss of flow fluid past valve channel , the flow state of fluid in valves becomes the most important factor for the operational property of valves
由于水压阀是通过控制流体流动来操作系统的，阀的压降也来自于流体流经阀道时的能量损失，因此阀内的流体流动状态就成为决定阀操作性能最为重要的因素。 - Water hydraulics will take place of oil hydraulics step by step . spool valves and poppet valves are not only the key components but also the main components for energy loss , so the property of water hydraulic valves is significant for water hydraulic control system
在水压控制系统中，滑阀和锥阀是构成水压控制系统不可缺少的元件，同时水压阀也是产生能耗的一类主要元件，因此水压阀的性能对整个系统的性能起着至关重要的作用。 - At the same time , the pressure of dynamic state in different opening and closing velocities can be gained , on the basis of results the axial hydraulic force and the fluid force can be calculated , which offers reference and guide foundations for accurately calculating the drive force on water hydraulic valves
同时cfd解析也可以得到不同启闭速度下阀腔内的动态压力，在此基础上计算出作用于水压阀阀芯的稳态和瞬态轴向液动力，对精确计算阀芯驱动力具有重要的参考价值和指导意义。 - Hydraulic pound , vibrate , noise and cavitation are the main difficult problems in water hydraulic valves , and finite element numerical analysis is proved to be an effective computational method , so numerical simulation and visualizing research on the flow field in water hydraulic valves by applying finite volume method is very important
水压阀中的液压冲击、振动、噪声以及水压阀中的气蚀是研制水压阀存在的主要难题，而有限体积数值计算方法又被证实是一种可行而有效的流场计算法，因此应用有限体积法对水压阀阀道内流场进行数值模拟和可视化研究，是非常有意义，也是非常重要的。
