各种阀门[VALVE]的基本介绍阀门是国民经济建设中使用极为广泛的一种机械产品。
阀门在石油、天然气、煤炭、冶金、和矿石的开采、提炼加工和管道输送系统中；阀门在石油化工、化工产品，医药，和食品生产系统中；阀门在水电、火电和核电的电力生产系统中；阀门在城建的给排水、供热和供气系统中；阀门在冶金生产系统中；阀门在船舶、车辆、飞机、航天以及各种运动机械的使用流体系统中；阀门在国防生产以及新技术领域里；阀门在农业排灌系统中都有大量的需求。
Valve is a widely used mechanical product in each country's economy. You can find valves commonly used in the following fields like oil, nature gas, coal, metallurgy, mining, refinery, pipe transportation, petrochemical, chemical, pharmacy, food production, power plant, water supply / drainage, heat supply, air supply, marine, vehicle, airplane, spacecraft, military, new tech, irrigation and many other flowing systems.阀门分自动阀门与驱动阀门。
自动阀门（如安全阀、减压阀、蒸汽疏水阀、止回阀）是靠装置或管道本身的介质压力的变化达到启闭目的的。
驱动阀门（闸阀、截止阀、球阀、蝶阀等）是靠驱动装置（手动、电动、液动、气动等）驱动控制装置或管道中介质的压力、流量和方向。
由于介质的压力、温度、流量和物理化学性质的不同，对装置和管道系统的控制要求和使用要求也不同，所以阀门的种类规格非常多。
剧不完全统计，我国的阀门产品品种已达四千多个型号，近四万个规格，阀门在经济生活中起着非常大的作用。
There are self-driven valves and operated valves. self-driven valves( like safety valve, relief valve, steam trap, check valve ) are functioning by utilizing its mechanical design or the pressure, direction of its flow medium.operated valve( like gate valve, globe valve, ball valve, butterfly valve ) is fuctioning by actuator( manual, electric, hydraulic, pneumatic etc. ) or the pressure , flow direction of its medium. due to the differences of pressure, temperature, flow, and physical-chemical character of its medium , there are different requirements in designing and applying the pipeline system.therefore there are numerous types of valve.according to an unofficial statistics, there are more than four thousand types of valve with approximately forty thousand specifications in China. Obviously, valve is an important element in the social economy.电磁阀[SOLENOID VALVE]电磁阀是用来控制流体的自动化基础元件，属于执行器；并不限于液压，气动。
电磁阀用于控制液压流动方向，工厂的机械装置一般都由液压钢控制，所以就会用到电磁阀。
而通常意义上，国内电磁阀厂家也并不以液压电磁阀为主打，一般多生产二位二通气液用电磁阀。
Solenoid valve is a basic component in automatic flow control, it is actuator but not limited to hydraulic, pneumatic. solenoid valve is mainly used to control the direction of hydraulic flow, machines in plant are usually controled by hydraulic cylinder and thus the solenoid valve is applyed. generally , solenoid valve manufacturers in China not only produce hydraulic solenoid valve, they mainly manufacturer hydraulic-pneumatic combined two way solenoid valve.电磁阀的工作原理，电磁阀里有密闭的腔，在的不同位置开有通孔，每个孔都通向不同的油管，腔中间是阀，两面是两块电磁铁，哪面的磁铁线圈通电阀体就会被吸引到哪边，通过控制阀体的移动来档住或漏出不同的排油的孔，而进油孔是常开的，液压油就会进入不同的排油管，然后通过油的压力来推动油刚的活塞，活塞又带动活塞杆，活塞竿带动机械装置动。
这样通过控制电磁铁的电流就控制了机械运动。
The main working theory of solenoid valve is that there is a fully closed cabinet inside the solenoid valve,with holes in different position. each hole is connected with different hose.the valve is centered with two electric magnets aside, when the power is on, the valve will be pulled to that side.though the movement of the valve, the hole which is connected to the hose will be closed / open, the oil inlet is always open, the hydraulic oil flows to different hoses and push the cylinder piston by its pressure.the piston drives the piston stem and then the equipment into movement. by this means, the mechanical movement can be controled by controling the electricity of solenoid valve.球阀[BALL VALVE]球阀和旋塞阀是同属一个类型的阀门，只有它的关闭件是个球体，球体绕阀体中心线作旋转来达到开启、关闭的一种阀门。
Ball valve and plug valve is the same type of valves only its closure of a spheroid, spheroid around a rotary axis lines to achieve valve body opened and closed a valve球阀在管路中主要用来做切断、分配和改变介质的流动方向。
球阀是近年来被广泛采用的一种新型阀门，它具有以下优点：1．球阀流体阻力小，其阻力系数与同长度的管段相等。
2．球阀结构简单、体积小、重量轻。
3．球阀紧密可靠，目前球阀的密封面材料广泛使用塑料、密封性好，在真空系统中也已广泛使用。
4．球阀操作方便，开闭迅速，从全开到全关只要旋转90°，便于远距离的控制。
5．球阀维修方便，球阀结构简单，密封圈一般都是活动的，拆卸更换都比较方便。
6．球阀在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀。
7．球阀适用范围广，通径从小到几毫米，大到几米，从高真空至高压力都可应用。
Ball valve used to be cut off in the main line, distribution and change the direction of the flow medium. Ball valve is widely used in recent years a new type of valves, it has the following advantages : 1. Ball valve fluid resistance small, and its resistance coefficient with the length of the barrel of equivalent. 2. Ball valve structure simple, small size, light weight. 3. Ball valve closely reliable, current Ball valve sealed surface material widely used plastic, undergo good in a vacuum system also has been widely used.4. Ball valve easy to operate, the closing rapidly, from open all around, as long as there 90E, facilitate remote control.5. Ball valve maintenance convenience Ball valve structure simple. seal ring generally activities, the removal of the replacement is more convenient.6. Ball valve whole or in the open all closed, spheroid and the sealed surface with medium valve seat separation medium through, will not cause the valves sealed surface erosion.7. Ball valve application scope Link Drive from small to several millimetres, a few meters in from the high pressure can be high vacuum applications.蝶阀[BUTTERFLY VALVE]蝶阀是用随阀杆转动的圆形蝶板作启闭件,以实现启闭动作的阀门.蝶阀主要用截断阀使用,亦可设计成具有调节或截断兼调节的功能.目前蝶阀在低压大中口径管道上的使用越来越多Butterfly valve is on/off by the turning of the stem which operate the round butterfly disc. It is mainly used as cut-off valve and also can be designed as regulating or cut-off / regulating combined valve. currently , butterfly is mainly used in the low pressure large size pipelines.蝶阀的蝶板安装于管道的直径方向。
