           电磁阀是用来控制流体方向的自动化基础元件，属于执行器；通常用于机械控制和工业阀门使用，对介质方向进行控制，从而达到对阀门开关的控制电磁阀工作原理：　

　电磁阀里有密闭的腔，在不同位置都开有通孔，针型阀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挡住或漏出不同的排油的孔， 呼吸阀而进油的孔是常开的，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缸的活塞，活塞又带动活塞杆，活塞杆带动机械装置运动。这样通过控制电磁铁的电流通断就控制了机械运动。

 　　目前使用的蒸汽电磁阀，通常是过以下两种蒸汽的：

　　1、锅炉蒸汽-饱和蒸汽温度压力相对稳定，调节阀温度低于250℃，工作压力低于1.6Mp。上海星瓯阀门制造有限公司通常会选用软密封的蒸汽电磁阀如下：

　　结构特点：本阀是由副阀和主阀两大部件构成的先导式二次开阀的电磁阀。

　　耐热：电磁部分、密封件部分用特种耐高温电工材料和密封材料，并应用了各种隔热措施。

　　耐磨：选材合理，阀杯和导向套间巧妙地利用流体的润滑作用，减少磨损，提高寿命。

　　耐冷凝：蒸汽管道的冷凝水是影响蒸汽电磁阀动作的重要因素，本阀则不受冷凝水影响。

　　其他用途-软密封　

　蒸汽电磁阀　

　本系列电磁阀还可广泛地应用纺织、锻钢阀门印刷、化工、塑料、橡胶、制药、食品、建材、机械、电器、表面处理和科研部门以及浴室、食堂、空调等自控系统。

　　2、热电厂出来的蒸汽-过热蒸汽温度压力变化基数较大，温度最高可达400以上，工作压力则低于4.0Mpa。通常会选用硬密封的蒸汽电磁阀如下：

　　结构特点：采用金属硬密封，减压阀提高了产品的使用温度及使用寿命。

　　选材合理，阀杯和导向套间巧妙地利用流体的润滑作用，以减少磨损。

　　其他用途-硬密封蒸汽电磁阀本产品通用介质范围较广，可分别使用于水、轻油、重油、非腐蚀性气体及蒸汽等流体。如电站抽气管道疏水系统和蒸发器的排气系统中，主要是对管道中的介质进行双位自动调节和远程控制。

　　工作状态：常闭型-通电打开、断电关闭常开型-断电打开、通电关闭。

          Solenoid valve is used to control the direction of fluid based automation components, is actuator; commonly used in machine control and industrial valves used to control the direction of the medium to achieve the control switch on the valve solenoid valve works: Solenoid valve in a closed chamber, in different locations all with holes, each hole leads to a different pipeline, valve chamber in the middle, both sides are two electromagnets, which face the magnetMUD VALVES coils body will be attracted to which side, by controlling the body's movement to block the discharge of oil or leakage of different holes, and into the oil hole is always open, hydraulic oil flows to different hoses, then the oil pressure to push oil cylinder piston, piston rod has driven, piston rod drive mechanism movement. This electrical flow by controlling the electromagnet to control the mechanical movement off. Current steam solenoid valve, usually REDUCING VALVESover the following two steam: 1, the boiler steam - saturated steam temperature and pressure is relatively stable at temperatures below 250 ℃, working pressure less than 1.6Mp. Valve Manufacturing Co., Ltd. Shanghai StarSAFETY VALVES Ou soft seal will usually use the steam solenoid valve as follows: Structural features: The valve is a valve and main valve Vice constitute the two major components of the pilot-type valve second opening solenoid valve. Heat: electromagnetic part, some with special high temperature seals and sealing materials, electrical materials, and apply a variety of insulation measures. Wear: selection and reasonable guidance suite valve cup and clever use of fluid lubrication, reduce wear, increase life expectancy. Resistance to condensation: condensation of steam pipeline valve on the steam water is an important factor in action, the valve is not subject to condensation effects. Other uses - soft sealing Steam solenoid valve This series solenoid valve can beMULTI-FUNCTIONAL WATER PUMP CONTROL VALVE widely used in textile, printing, chemicals, plastics, rubber, pharmaceutical, food, building materials, machinery, electronics, surface treatment and research sectors and bathroom, dining room, air conditioning automatic control system. 2, thermal power plants out of steam - superheated steam temperature and pressure changes of a high base temperaturePLUG VALVES up to 400 more job stress than 4.0Mpa. Often used the steam valve seal as follows: Structural features: The metal seal, increased temperature and lifetime use of the product. Material selection reasonable guidance suite valve cup and clever use of fluid lubrication to reduce wear and tear. Other purposes - steam valve seal common medium of the broader product can be used separately in water, light oil, heavy oil, gas and steam and other non-corrosive fluid. Such as the power plant exhaust pipe evaporator drain system and exhaust system, mainly in the media pipeline to double automatically adjust and remote control. Working state: normally closed - power open, power close the normally open type - power open, power close.
