查询词典 poppet valve

Inline valve is one type of the poppet valves.

型阀是属截止阀的一种。

When the flow through the balance of the piston damping the flow of holes increases, the balance of the piston, the next increase in pressure on both sides of a balanced increase in the distance the piston increases, and vice versa reduced; and also because the spring stiffness is very small, so that shift the balance of the piston pressure required very few changes, so the flow through the Poppet head is not much change, so the first opening Poppet very few changes, to mention the pressure of moving the first opening can be said to remain unchanged, that is, when the pilot valve spring after a set, Poppet Head was opened, the balance piston chamber pressure remained basically unchanged.

当流经平衡活塞上阻尼孔的流量增加时，平衡活塞上、下两侧的压差增加，平衡活塞上升距离增加，反之则减小；又因为弹簧的刚度很小，使平衡活塞上移所需压差变化很小，所以通过提动头的流量变化也不大，因此提动头的开口变化很小，提动头开启的压力可以说是不变的，亦即当先导阀的弹簧一经设定后，提动头被打开时的平衡活塞上腔的压力基本保持不变。

The effect of structural forms, angle of poppet, and chamfer of valve seat on the flow field within cone valve is investigated emphatically by analyzing the form of stream line, the data and distribution of pressure and velocity.

通过对流场内流线形状、压力和流速的大小及其分布情况进行分析，着重研究了阀芯半锥角、阀芯结构、阀座倒角等对锥阀流场的影响。

Poppet type valve with the comparison, this valve working stroke to be larger.

与提动式换向阀相比较，这种换向阀工作行程要大一些。

At last, according to the effect of orifice configuration on the cavitation, the several poppet configurations of a relief valve were designed in order to suppress cavitation, the cavitating flow simulation for different configuration were performed and compared in ordet to find a optimal conriguration.

最后，针对阀口形状对气穴的影响，为了抑制阀口气穴，对溢流阀阀芯形状进行了改进，设计了几种不同的阀芯结构，分别对不同的阀芯进行了气穴流场分析和比较，来寻求优化的阀芯结构。

The effects of inlet velocity, outlet pressure, opening size as well as cone angle on cavitation intensity in the water hydraulic poppet valve were numerically investigated.

分析了进口流速，出口压力，阀口开度和阀芯锥角对纯水液压锥阀阀口气穴强度的影响。

In the paper, based on reading and studying a great number of references about fluid dynamic technique and numerical computing methods of flow field, 3-D Numerical simulations and visual analysis of the flow field in hydraulic poppet valve with inside flow work condition were obtained by CFD software Fluent.

本文在参阅大量国内外有关计算流体力学和流场数值计算方法相关资料的基础上，用CFD软件Fluent对内流工况液压锥阀内部流场进行了三维数值模拟及可视化分析。

With the help of performance test of reciprocating pump, the design for the spring was validated. An experiment-bed was also built to test the poppet valve's lift displacement. The testing results prove that the simulation was in a correct way.

设计了往复泵泵阀试验台；通过对往复泵进行性能测试，对不同弹簧预紧力下阀门升程进行了测定，验证了仿真结果的合理性。

The simulation results show that the spring stiffness and initial force have important effect on the poppet valve's opening displacement, the delay-closing time and the closing velocity, and there must be an optimal matching between those two spring factors.

仿真结果表明，在同时保证阀芯有较大的开启度和较短的滞后关闭时间时，弹簧刚度和预紧力因素之间存在着最佳组合：k=10 N/cm，f=15N；同等地改变预紧力比改变弹簧刚度，对阀门的运动影响更大。

When the load smaller than the first outlet pressure adjustment valve set pressure, pilot valve Poppet head off an oil chamber, oil chamber 2 is equal to the pressure on the outlet pressure, the main valve of the sliding shaft 2 inside the cavity in the oil a rigid under the action of a small spring at the lowest position, the main valve and the valve slider protruding shoulder posed by all the valve port opens, pressure reducing valve without decompression.

当负载较小，出口压力低于先阀的调定压力时，先导阀的提动头关闭，油腔1、油腔2的压力均等于出口压力，主阀的滑轴在油腔2里面的一根刚性很小的弹簧作用下处于最低位置，主阀滑轴凸肩和阀体所构成的阀口全部打开，减压阀无减压作用。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
