Axle The primary shafting connection between a wheel and a housing is an axleilt may simply be the extension of a round member from each side of the rear of a wagon, and on the end of each the hub of a wagon wheel rotates.

轮轴 轮子与壳体之间主要的传动轴连接称为轮轴。简单地说，它可以是从四轮马车后部两侧伸出的圆形构件，四轮马车车轮的轮毅在其每个端部旋转。

In the meantime, the temperature of the bus under natural cooling condition is computed by numerical calculation. If the temperature does not meet the requirement, the two schemes of forced ventilation are posed and compared. At last, the ventilating fan is selected on the basis of analysis.

针对垂直布置的母线进行了详细分析，建立了垂直布置的母线的传热模型，确定了计算母线壳体温度和导体温度的数值计算方法，并根据所得结果提出了在工程应用中可以采用的垂直布置的母线散通风方案。

In the direction of flow between the first cross section (50) of flow and the second cross section (52) of flow, a third cross section (54) of flow is formed between the valve member (40) and the valve housing (36), said third cross section (54) of flow being larger than the first cross section (50) of flow and the second cross section (52) of flow.

在流动方向上在第一通流横截面(50)与第二通流横截面(52)之间在阀元件(40)与阀壳体(36)之间形成第三通流横截面(54)，该第三通流横截面大于第一通流横截面(50)和第二通流横截面(52)。

The seal test Test the stem and the valve cover seal sealing performance of the test, Deputy Shell Test Such as the valve body and valve cover is made of the valve housing connected to the pressure test.

上密封试验检验阀杆与阀盖密封副密封性能的试验壳体试验对阀体和阀盖等联结而成的整个阀门外壳进行的压力试验。

Gas valve body material selection Pressure gas pipeline under the reasonable use of the valve housing material selection, not only palace to meet the safe operation of pipeline and is able to reduce the cost and make the best use for the purpose.

三、燃气阀门的阀体材质选用根据燃气管线的使用压力合理选用阀门壳体材质，既宫满足管线的安全运行又能达到减少造价，物尽其用的目的。

The scope of their business is: producing aluminum castings, such as brake caliper, master cylinder, engine bracket, intake manifold, steering housing, valve, compressor housing and all the demands of high-quality products in the field including the auto industry, electronics industry and hydraulic industry.

其经营范围：制作铝合金铸件、生产缸体、制动钳、发动机支架、进气岐管、转向伐体、阀体支架、涡轮增压器、壳体以及所有要求高质量的零件：汽车工业、电子技术工业、液压工业等。

Valve housing and components used, such as the United States and build the Association ASTM standards, has monel, titanium, zirconium material, tantalum material Hastelloy, ultra-low carbon, alloy steel, stainless steel, carbon steel, etc..

阀门壳体及零部件采用美材协ASTM等标准，有蒙乃尔、钛合金、锆材、钽材哈氏合金、超低碳、合金钢、不锈钢、碳钢等。

The most important are as follows: Detection of type: valve stem seal leakage test and test; water valve tightness test; switch tightness test; the take-off safety valve Test; Detection Object: valve, the cut-off valve , safety valve, throttle valve, check valve, swing check valve, ball valve, regulating valve and other hollow pump body, valve body and housing, etc.; way valve connection: flange connection, threaded connection, welding connection; detection medium.

最重要的有以下几种：检测类型：阀门密封性试验及阀杆泄漏性试验；水中阀体密封性试验；开关密封性试验；安全阀的起跳值试验；检测对象：闸阀、截止阀、安全阀、节流阀、止回阀、摆动式逆止阀、球阀、调节阀和其他中空的泵体、阀体和壳体等；阀门联接方式：法兰联接、螺纹连接、焊接联接；检测介质。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
