<p>ZCM煤气电磁阀具有结构简单、流量大，寿命长，安全可靠等特点。适用于城市煤气、液化石油气、天然气等多种煤气为加热燃烧介质管路作二位式通断切换，进行温度自动控制的执行结构，它广泛应用于纺织业、印染业的煤气热定型和玻璃、灯泡业的窑炉加热及其它行业的煤气加热自控系统。</p> <p><strong>二、电磁阀型号规格说明</strong></p> <p><strong>三、结构及原理</strong></p> <p>本阀系一次开阀的直动式低压电磁阀。控制介质通断的阀口密封垫，通过阀杆直接与活动铁芯相连。</p> <p>根据断电时所处开关状态的不同可分为常闭电磁阀和常开电磁阀，常闭电磁阀，断电常位时，靠衔铁自重、密封弹簧及介质压力将阀口封住，切断了被控介质的流道。</p> <p>电磁线圈通电后，电磁阀克服衔铁自重及密封弹簧、介质压力的作用力将活动铁芯连同阀口密封垫吸上，打开阀口，被控介质便可流通了。</p> <p>常开电磁阀断电时，电磁吸力等于零，在弹簧的作用下把动铁芯、阀杆向上提起，阀门打开，介质流通。当通电时由于吸力作用动铁芯下移，推动阀杆，阀门关闭，介质断止。</p> <p><strong>四、煤气电磁阀主要技术参数</strong></p> <table

<p> <strong>六、安装须知</strong></p> <p>1、安装时电磁阀线圈向上，并保持垂直位置，电磁阀上箭头或标记应与管道流向*，不得安装在有溅水或漏水的地方。</p> <p>2、电磁阀的工作介质应清洁无颗粒杂质，电磁阀内件表面上的污物及过滤器，需定期清洁干净。</p> <p>3、在电磁阀发生故障时，为了及时隔离电磁阀，并保证系统正常运行，安装旁路装置（如图一）。</p> <p>4、在管路系统中，安装在支路上的电磁阀通径应小于主管道阀门的通径（如图二）。</p> <p>5、安装电磁阀前，管道必须清洗干净。建议在电磁阀前安装过滤器，蒸汽管道安装疏水阀。</p> <p>6、不能将电磁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防碍动作。</p> <p>7、普通型电磁阀不能在爆炸危险场合使用。</p> <p>8、在管路刚性不足情况下，建议把电磁阀前管道用支架固定，以免电磁阀工作时引起振动。</p> <p>9、在安装电磁阀前，要注意看清产品电磁阀标牌，认真阅读使用说明书电磁阀，判断电磁阀产品是否符合使用条件。</p> <p>10、电磁阀前后管道上需安装压力表，以便观察管道压力。</p> <p><strong>七、使用保养</strong></p> <p>1、建议使用单位派专人负责使用保养。</p> <p>2、电磁阀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。</p> <p>3、应定期清洗大阀内外及衔吸合面的污物，注意不要损坏密封面。</p> <p>4、电磁阀较长时间不用时，应关闭阀前手动阀，重新启用时，蒸汽电磁阀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。</p> <p>5、电磁阀从管路上卸下不用时，应将内部零件拭净并用压缩空气吹净储存。</p> <p>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，现和阀座研磨。</p> <p>7、工作时，要注意阀门前后压力表，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，电磁阀要停止使用，关闭前后手动阀，以免电磁阀爆炸和泄漏。</p> <p><strong>八、订货须知</strong></p> <p>1、订货时请注明型号、公称通径、公称压力、工作介质、工作压差、介质温度、电源电压及功率、介质粘度。</p> <p> </p> <table border="0" cellpadding="0" cellspacing="0"> <tbody> <tr> <td rowspan="2"> <p>2、电磁阀正常工作时的电压为220</p> </td> <td>+22</td> <td rowspan="2"> <p>V，如超过此范围，请订货时注明电压波动量。其它规格电源电压可做特殊订货。</p> </td> </tr> <tr> <td>-15</td> </tr> </tbody> </table> <p> </p> <p>3、阀门的开通时间达12小时以上，请选用常开式电磁阀。当使用环境周围有易燃易爆品，请选用防爆型电磁阀。（防爆型结构如下图三）</p> </td>
