阀体

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。

Through the valve to reduce the diameter to increase the opening work, the specific ways:① replace a file of small-caliber valve, such as DN32 replaced DN25;② body does not change, the replacement of small diameter spool valve seat Block.

通过把阀的口径减小来增大工作开度，具体办法有：①换一台小一档口径的阀，如DN32换成DN25；②阀体不变更，更换小阀座直径的阀芯阀座。

The percentage of linear and so quick Figure 1 Three common control valve sleeve sleeve diagram Interchangeability of parts from Ball Valves the valve to see some adjusting mechanism trim can be easily replaced and maintained, for example, the sleeve valve sleeve can be easily replaced to achieve different flow characteristics; top and bottom-oriented trim can be easily turn the spool and the valve seat to achieve positive and anti-body to replace the valve body to achieve the air to open the way to replace gas off; valve isolation valve can be easily dismantled for the seat replacement and cleaning.

快开 线性等百分比图1 三种常用套筒控制阀的套筒示意图从阀内件的互换性看，一些调节机构的阀内件可方便地更换和维护，例如，套筒阀可方便地更换套筒实现不同流量特性；顶底导向的阀内件可方便地翻转阀芯和阀座来实现正体阀与反体阀的更换，从而实现气开和气关方式的更换；阀体分离阀可方便地拆卸，用于阀座更换和清洗。

The domestic factory on only the test platform examines its function and to the valve chest clean generally before the direction valve installment, therefore the use initial period appears the breakdown frequently, but overseas equipment actually not similar phenomenon.

国内厂家在方向阀安装前一般只上试验台检验其机能并对阀体清洗，因此使用初期经常出现故障，而国外设备却无类似现象。

It is for the valve chamber to provide the main hole to install the internal parts, but can be an integral part of the valve.

它为阀腔提供主要的开孔以安装内部零件，也可以是阀体的一个不可分割的部分。

This subject is a try of Valve body special-purpose casting technology CAD system.

本课题是阀体专用铸造工艺CAD系统方面的一个尝试。

The numerical simulation of temperature field and shrinkage defect prediction for a valve casting, which was involved in 4 kinds of casting proces.

对采用 4种不同铸造工艺方案的阀体铸件凝固过程进行了数值模拟及缺陷预测，获得了与试验相一致的模拟结果。

Soft sealing gate valve body, valve cover using precision casting in metal, a shape, the basic non-mechanical processing, do not use sealed copper ring, saving non-ferrous metals.

软密封闸阀的阀体、阀盖采用精密铸造法铸造，一次成型，基本不机械加工，不使用密封铜环，节约有色金属。

In recent ten years, the company mainly supply various specifications of ball valve steel casting and every kinds of trucks steel casting to USA, heat-resisting steel frame to Japanese heat treatment enterprises, and locks steel casting for vessel container to worldwide countries.

近十年来，本公司主要为美国提供各种规格球阀阀体铸钢件和载重汽车上使用的各种铸钢件；为日本热处理企业提供耐热钢框；为世界各国船用集装箱提供锁具铸钢件。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
