本技术属于燃气电磁阀门
,尤其涉及一种新型常闭电磁阀门。
技术介绍
目前,业内常用的现有技术是这样的:目前市面的燃气常闭电磁阀门都是为直动式电磁阀门,其结构原理为在圆型线圈内穿入活塞,通电后线圈产生磁场,利用其磁场的大小来吸住活塞向上吸住,阀门气路通道打开,断电后,磁场消失,活塞向下移动,阻档了阀门的气道;由于,向上吸力是依靠磁场吸力实现的,因此不同的阀体大小其压力都不一样,所需要的线圈大小尺寸不一,不同的阀体要不同的线圈同时由于自身原理的缺陷,给生产及售后及为不便。综上所述,现有技术存在的问题是:现有的燃气常闭电磁阀门向上吸力是依靠磁场吸力实现的,不同的阀体要不同的线圈同时由于自身原理的缺陷,给生产及售后及为不便。
