The amendment increases the CAA the use of straight travel valve chemical companies, refineries and other production enterprises using the valve in the prevention of leakage of the valve on the outside input.

CAA修正案增加了使用直行程阀门的化工公司、炼油厂及其它使用阀的生产企业在防止阀门外泄漏上的投入。

Angle type valve to cut off travel greater pressure because of media in the spool or the valve plate force generated by the rotational axis of the torque produced is very small, Check Valves so it can withstand a greater pressure differential.

角行程类阀的切断压差较大，是因为介质在阀芯或阀板上产生的合力对转动轴产生的力矩非常小，因此，它能承受较大的压差。

With the application of theory and technology of programmable logic controller -PLC, the control system of transplanting potted seedlings manipulator was developed. First, the hardware of control system for transplanting seedlings manipulator was designed in detail, including the implement components, electrical control components and sensors. Then the design and selection of cylinder, solenoid valve and travel switch, configuration of I/O interface and wiring of PLC were completed and ladder chart and repertoire were drawn up.

应用PLC技术设计开发了穴盘苗自动移栽机械手的控制系统详细地介绍了硬件结构即电气系统的设计，包括气缸、电磁阀及行程开关的选择、IO接点的分配及PLC接线图的设计，编制出机械手运动过程梯形图和指令表程序，完成了控制系统的安装和调试。

The executing agency can or piston is divided into: double-acting type, therefore, can be either upward to produce the greatest driving force; or divided into spring-reset, and therefore loss of gas supply, the executing agency will follow the requirements of the valve travel direction.

活塞式执行机构可以或者分为：双作用式，因此，在任一方向上都可产生最大的驱动力；或者分为弹簧复位式，因此在失去气源时，执行机构会使阀门沿着要求的行程方向移动。

Rotary control valve is a control valve, control valve also includes a number of straight travel valve, such as cut-off valves, gate valves, diaphragm valves.

旋转调节阀是一种控制阀，控制阀还包括一些直行程阀如截止阀、闸阀、隔膜阀。

This allows the valve in a 90 ° travel range are completely sealed from the deputy, not only to strengthen the cam effect, it completely eliminates friction; the same time close the valve, when the seal pair gradually closed, resulting in "wedge effect" to minimum torque to achieve the most rigorous off.

这样使得阀门在90°行程范围内，密封副之间完全脱离，既加强了凸轮效应，又完全消除了摩擦；同时关闭阀门时，当密封副逐渐闭合，产生&楔块效应&，以最小的扭矩实现最严密的关断。

On the basis of API standards and relevant Chinese standards, the dynamic characteristics of the homemade gas lift valves used in Wendong Oilfield are tested and analyzed. The dynamic characteristic parameters tested include debuging opening pressure, bellows bearing capacity, travel of valve rod, flow rate and valve leakage.

以API11V2—1995标准和国内3项与气举采油相关的石油行业标准为基础，依靠已建成的气举阀动态特性测试试验室，对文东油田使用的国产气举阀进行了调试台打开压力、波纹管承载率、阀杆行程、流量参数和气举阀漏失量等5项动态特性参数研究和现场测试。

On the actual project simplified and abstract processing, on the basis of the characteristics of the project site will represent the quantities, as data object defined, such as travel switch hige, solenoid valve and electricity, piston rod location and size of pressure can be defined as the data object.

在对实际现场工程进行简化和抽象处理的基础上，将代表现场工程特征的各物理量，作为数据对象加以定义，如行程开关通断、电磁阀得失电、活塞杆位置、压力大小等都可定义为数据对象。

Straight trip valve through a linear motion components such as the gate to allow or cut off the logistics.

直行程阀通过一个直线运动的部件如闸板来允许或切断物流。

A new valve design is proposed by shortening stroke distance of the valve,altering motion condition im magnetic field and picking a magnetic saturated alloyof iron and nickel as the material for the valve.

经缩短阀片行程距离，改变其在磁场中运动状态，并选用IJ50较高磁饱和铁镍软磁合金为阀片材料试验。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
