  The valve is produces along with the fluid pipeline production.The humanity used the valve already to have the nearly 4000 history.Our country ancient times when attracted the bittern salt-making from the brine well, once in the bamboo system pipeline has used the wooden plug valve.In 1800, ancient Egyptian in order to prevent the Nile River is in flood constructs the large-scale hydraulic engineering is, also once used the similar wooden cock to control fluent the assignment.These all are the valve embryonic forms. The industrial used valve massive applications, will be later only then start from the watt invention steam engine.At the beginning of the 20th century appeared the cast steel, the forging steel and the forge welding structure valve. “Fa”the definition is in the fluid system, uses for to control the fluid the direction, the pressure, the current capacity installment.The valve is causes in the tubing and the equipment medium flowing or the stop and can control its current capacity the installment. The valve is in the pipeline fluid expulsion system the control portion, it is uses for to change the circuit cross section and the medium flow direction, has functions and so on conduction current, closure, adjustment, throttle, prevent returning, divergence or overflow release of pressure. Uses in the fluid control the valve, from the simple cut-off valve to the limit each kind of valve which uses for the complex automatic control system in, its variety and the specification are many, the valve nominal size greatly reaches 10m from the extremely small measuring appliance valve to the latus rectum the industry pipeline to use the valve.The valve available in the control water, the steam, the oil quality, the gas, the mud, each corrosive medium, the liquid metal and the radioactive fluid and so on each kind of type fluid flowing, the valve working pressure may from 0.0013MPa to the 1000MPa ultrahigh voltage, the operating temperature from - 269℃ ultralow temperature to 1430℃ high temperature.The valve control may use many kinds of type of drive, like manual, electrically operated, the fluid moves, air operated, the worm gear, the electromagnetism moves, the electromagnetism--The fluid moves, the electricity--The fluid moves, the gas--The fluid moves, the spur gear, the bevel gear actuation and so on; May in the pressure, the temperature or under other form sensing signal function, according to the predetermined request movement, or does not rely on the sensing signal to carry on simple opening or the closure, the valve dependence actuation or the automatic organization causes to open shuts to make the fluctuation, the slipping, turns on lathe suspends or the gyroscopic motion, thus changes its flow channel area the size to realize its control function. 阀门是随着流体管路的产生而产生的。人类使用阀门已经有近4000年的历史了。我国古代从盐井中吸卤水制盐时，就曾在竹制管路中使用过木塞阀。公元前 1800年，古埃及人为了防止尼罗河泛滥而修建大规模水利工程是，也曾采用过类似的木制旋塞来控制水流的分配。这些都是阀门的雏形。 工业用阀门的大量应用，是从瓦特发明蒸汽机以后 才开始的。二十世纪初出现了铸钢、锻钢和锻焊结构的阀门。 “阀”的定义是在流体系统中，用来控制流体的方向，压力，流量的装置。阀门是使配管和设备内的介质流动或停止并能控制其流量的装置。 阀门是管路流体输送系统中控制部件，它是用来改变通路断面和介质流动方向，具有导流、截止、调节、节流、止回、分流或溢流卸压等功能。 用于流体控制的阀门，从最简单的截止阀到极为复杂的自控系统中所用的各种阀门，其品种和规格繁多， 阀门的公称通径从极微小的仪表阀大至通径达10m的工业管路用阀。阀门可用于控制水、蒸汽、油品、气体、泥浆、各种腐蚀性介质、 液态金属和放射性流体等各种类型流体的流动 ，阀门的工作压力可从0.0013MPa到1000MPa 的超高压，工作温度从-269℃的超低温到1430℃的高温。阀门的控制可采用多种传动方式， 如手动、电动、液动、气动、蜗轮、电磁动、电磁－－液动、电－－液动、气－－液动、正齿轮、伞齿轮驱动等；可以在压力、温度或其它形式传感信号的作用下， 按预定的要求动作，或者不依赖传感信号而进行简单的开启或关闭，阀门依靠驱动或自动机构使启闭件作升降、滑移、旋摆或回转运动， 从而改变其流道面积的大小以实现其控制功能。 8000字难度啊 对不起了 我只能帮你这些 抱歉啊
