<p><strong><span style="color:#000000;font-size:x-small;">一．特 征</span></strong></p>
<p align="left"><span style="color:#000000;font-size:x-small;"> 本阀是先导直动型的<strong>电磁阀</strong>,其通用介质范围比较广,可分别用水、轻油、重油、非腐蚀性气体及蒸汽等流体,如果电站抽气管道疏水系统和蒸发器的排气系统中,主要的对管道中的介质进行双位自动调节和远程控制。耐高温：采用金属硬密封，提高了使用温度。 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。 </span></p>
<p align="left"><span style="color:#000000;font-size:x-small;"><strong>电磁阀</strong>电磁铁通电时，连杆被提升，带动转轴转动，副阀打开。由于副阀被开启，主阀阀杯上部的压力流体被排出，因此主阀阀杯下部的压力比上部高，这样下部的压力将主阀阀杯向上推开。主阀被打开后，上下压力相等，阀杯在电磁力、上下压力作用下，置于平衡状态，<strong>阀门</strong>开通。断电时在衔铁自重及返回弹簧作用下，关下副阀，副阀关闭后，随之主阀阀杯上部的压力升高而将主阀阀杯压下，达到断流密封作。</span></p>
