介质说明 日常生活中我们接触到的蒸汽常分为两种，1、锅炉蒸汽-饱和蒸汽 2、热电厂出来的蒸汽-过热蒸汽 1、饱和蒸汽 温度压力相对稳定，温度低于250℃，工作压力低于1.6Mpa 2、过热蒸汽 温度压力变化基数较大 温度{zg}可达400℃以上，工作压力则低于4.0Mpa 　 对于{dy}种蒸汽，我们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、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。 　 对于第二种蒸汽，我们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，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

Media Help Everyday we are exposed to the steam often divided into two, one, the boiler steam - saturated steam 2, thermal power plants out of steam - superheated steam 1, a relatively stable temperature and pressure saturated steam, temperature lower than 250 ℃, working pressure lower than 1.6Mpa 2, superheated steam temperature and pressure changes of a high base temperature up to 400 ℃, working pressure is lower than 4.0Mpa For the first steam, we usually use soft sealing steam solenoid valve as follows: Structural characteristics This valve is a valve and main valve by the two vice components with the second open valve Pilot 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 will not affect the condensation water Other uses - soft sealing steam solenoid valve This series solenoid valve can be 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. For the second steam, we usually use the steam valve seal as follows: Structural characteristics 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 This product is broader general media 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
