<p align="left"><span style="font-size:x-small;"><span style="color:#e61a1a;"><strong>一、 </strong><strong>用途</strong></span></span></p>
<div><span style="font-size:x-small;"> 本阀适用于以蒸汽为加热介质，进行温度自动控制的执行机构。可对蒸汽加热器、散热器、干燥器等蒸汽设备及各类温度自控仪、蒸汽定型机、蒸染机、蒸汽回潮机等成套设备的锅炉蒸汽管道进行二位式自动控制和远程控制。广泛应用于染化、纺织、印染、食品、医药、卷烟、水泥制品、石油化工、冶金等部门的自控系统。</span></div>

<p align="center"><span style="font-size:x-small;"><img alt="" src="http://www.sh-valves.com/Web_editor/UploadFile/2008714105747343.gif" /></span></p>
<div><span style="font-size:x-small;"><span style="color:#f73809;"><strong>三、 </strong><strong>主要特点</strong></span></span></div>
<div><span style="font-size:x-small;">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。</span></div>
<div><span style="font-size:x-small;">耐磨：选项材合理，阀杯和导向套间巧妙地利用流体的润滑作用，减少磨损。</span></div>
<div><span style="font-size:x-small;">耐冷凝：蒸汽管道的冷凝水是影响蒸汽<strong>电磁阀</strong>动作的重要因素，本阀则不受冷凝水影响。</span></div>
<div> </div>
<div><span style="font-size:x-small;"><span style="color:#ee1111;"><strong>四、 </strong><strong>结构原理</strong></span></span></div>
<div><span style="font-size:x-small;"> 本阀是由副阀和主阀两大部件构成的先导式二次开阀的<strong>电磁阀</strong>。是靠副阀的启闭来控制主阀的通断。根据断电时所处开关状态的不同，可分为常闭<strong>电磁阀</strong>和常开<strong>电磁阀</strong>。常闭<strong>电磁阀</strong>，在断电常位时，副阀口封闭，主阀呈断路，当电讯号进入导阀线圈时，活动铁芯受电磁力作用吸上打开副阀口，主阀阀杯内压力迅速消失，介质压力将主阀阀杯托上，开启主阀口，工作介质便可流通。但当电讯号消失时，活动铁芯复位，封闭住副阀口，工作介质自平衡孔进入阀杯内，当压力趋于平衡时，靠主阀弹簧、阀杯自重及介质压力使阀杯下移，严密封住主阀口，阀又呈关闭状态。常开<strong>电磁阀</strong>，在断电常位时，由弹簧作用，副阀口打开，主阀流通。当电讯号进入副阀线圈时，活动铁芯受电磁作用吸下，副阀口封闭，工作介质经平衡孔进入阀杯内，当压力趋于平衡时，靠主阀弹簧、阀杯自重及介质压力使阀杯下移，严密封主阀口，<strong>阀门</strong>呈关闭状态。当主阀断电时，电磁力消失，副阀打开，主阀杯内压力迅速消失，介质压力将主阀阀杯托上，开启主阀口，介质流通，阀呈开启状态。</span></div>

<div><span style="color:#e6421a;"><span style="font-size:x-small;"><strong>七、 </strong><strong>安装须知</strong></span></span></div>
<div><span style="font-size:x-small;">1、 安装时<strong>电磁阀</strong>线圈向上，并保持垂直位置，<strong>电磁阀</strong>上箭头或标记应与管道流向一致，不得安装在有溅水或漏水的地方。</span></div>
<div><span style="font-size:x-small;">2、 <strong>电磁阀</strong>的工作介质应清洁无颗粒杂质，<strong>电磁阀</strong>内件表面上的污物及<strong>过滤器</strong>，需定期清洁干净。</span></div>
<div><span style="font-size:x-small;">3、 在<strong>电磁阀</strong>发生故障时，为了及时隔离<strong>电磁阀</strong>，并保证系统正常运行，最好安装旁路装置（如图一）。</span></div>
<div><span style="font-size:x-small;">4、 在管路系统中，安装在支路上的<strong>电磁阀</strong>通径应小于主管道<strong>阀门</strong>的通径（如图一）。</span></div>
<div><span style="font-size:x-small;">5、 安装<strong>电磁阀</strong>前，管道必须清洗干净。建议在阀前安装<strong>过滤器</strong>，蒸汽管道安装<strong>疏水阀</strong>阀。</span></div>
<div><span style="font-size:x-small;">6、 不能将阀安装在管道的低凹处，以免因蒸汽冷凝水、杂质等沉淀在阀内而妨碍动作。</span></div>
<div><span style="font-size:x-small;">7、 普通型不能在爆炸危险场合使用。</span></div>
<div><span style="font-size:x-small;">8、 在管路刚性不足情况下，建议把阀前管道用支架固定，以免<strong>电磁阀</strong>作时引起振动。</span></div>
<div><span style="font-size:x-small;">9、 在安装前，要注意看清产品标牌，认真阅读使用说明书，判断产是否符合使用条件。</span></div>
<div><span style="font-size:x-small;">10、 <strong>电磁阀</strong>前后管道上需安装压力表，以便观察管道压力。<br clear="all" />
</span></div>
<div><span style="color:#ee3d11;"><span style="font-size:x-small;"><strong>八、 </strong><strong>使用保养</strong></span></span></div>
<div><span style="font-size:x-small;">1、 建议使用单位派专人负责使用保养。</span></div>
<div><span style="font-size:x-small;">2、 <strong>电磁阀</strong>安装后需通入介质实验动作数次，确认正常后方可投入正式使用。</span></div>
<div><span style="font-size:x-small;">3、 应定期清洗大阀内外及衔铁吸合面的污物。注意不要损坏密封面。</span></div>
<div><span style="font-size:x-small;">4、 <strong>电磁阀</strong>较长时间不用时，应关闭阀前手动阀，重新启用时，蒸汽<strong>电磁阀</strong>应将冷凝水排除干净，并作试动作数次，待开关正常后方可投入使用。</span></div>
<div><span style="font-size:x-small;">5、 <strong>电磁阀</strong>从管路上卸下不用时，应将内部及零件拭净并用压缩空气吹净储存。</span></div>
<div><span style="font-size:x-small;">6、 使用时间较长时，如活塞与阀座间密封不好，可将活塞密封面重新磨平，再和阀座研磨。</span></div>
<div><span style="font-size:x-small;">7、 工作时，要注意<strong>阀门</strong>前后压力表，要求工作压力不得超过额定压力，工作压差必须在额定压差范围内。当工作压力超过额定压力或工作压差超过额定压差时，<strong>电磁阀</strong>要停止使用，关闭前后手动阀，以免<strong>电磁阀</strong>爆炸和泄漏。</span></div>
<div> </div>
