紧急切断燃气防爆电磁阀产品特点：
1、燃气防爆电磁阀芯均为不锈钢材料、活塞式结构，启闭迅速。
2、合理的密封材料和结构，密封性能更好、达到零泄漏。
3、紧急切断燃气防爆电磁阀使用寿命长达100万次。
4、长期停止动作后重新启动，动作同样灵敏。
5、接口尺寸通常为行业标准，用户可定做特殊接口。
6、一种具有外套型密封活塞环和具有高性能组合型密封活塞环的电磁阀。
常闭紧急切断燃气防爆电磁阀门失电后、迅速关闭；阀再次通电，不会自动打开，必须靠手动拉起阀，保持打开状态；节能、线圈保持功耗15W、温度不超过10℃、可长期通电；密封性好、零泄漏。
◆信号反馈：当阀打开时，信号公共线和开信号线接通；当阀关闭时，信号公共线和关信号线接通。
紧急切断燃气防爆电磁阀产品简介:
紧急切断燃气防爆电磁阀是与燃气报警器联动配套使用,它的原理是当探测器检测到有可燃气体泄露时，立即通过主机输出一个关闭电磁阀门的信号，快速关闭电磁阀门切断气源的供给，及时制止事故的发生。
常闭型燃气紧急切断电磁阀工作原理：
当电磁阀需打开时，电磁阀线圈先得电，然后把阀顶部的保护套旋下，用力向外拉起手柄，电磁阀打开，然后将保护套装在原位保护手柄。当电磁阀需关闭时，线圈瞬间是失电，电磁阀迅速关闭。
常开型燃气紧急切断电磁阀工作原理：
A：阀需要打开时，旋下防护罩（防护罩中间有螺纹孔型，将他旋在联动杆上当手柄使用），用力拉手柄，阀打开。
B：阀需要关闭时，线圈通电不超过1秒钟，阀在65毫秒内迅速关闭。
燃气紧急切断电磁阀正确使用方法:
1、燃气紧急切断电磁阀应安装在户内的总进气阀之后，以便之后检修。
2、燃气紧急切断阀安装后，须通入介质试动作数次，确认正常后方可投入正式使用。
3、应定期清洗大阀内外及衔铁吸合面的污物。
4、紧急切断防爆电磁阀从管路上卸下不用时，应将内部零件试净并用压缩空气吹净储存。
5、燃气紧急切断电磁阀较长时间不用时，应关闭阀前手动阀重新启用时，应将冷凝水排除干净并作试动作数次,待启闭正常后方可投入使用。
