Description
技术领域
本发明属于质子交换膜燃料电池配件的技术领域，具体涉及一种新型电磁阀。
背景技术
电磁阀是用电磁控制的工业设备，是用来控制流体的自动化基础元件，属于执行器，并不限于液压、气动。
燃料电池是一种将存在于燃料与氧化剂中的化学能直接转化为电能的发电装置。氢燃料电池是将氢气和氧气的化学能直接转换成电能的发电装置。其基本原理是电解水的逆反应，把氢和氧分别供给阳极和阴极，氢通过阳极向外扩散和电解质发生反应后，放出电子通过外部的负载到达阴极，在现有的质子交换膜燃料电池中，电磁阀的部件数量及精度要求都特别高，但在加工过程中，装配工序比较繁琐，并且部件稍有尺寸差距，就会造成装配不了，甚至会存在氢气泄漏，爆炸的风险。在后期出现检修拆卸时，会造成部件损坏，增加生产成本。
发明内容
本发明旨在解决上述缺陷，提供了一种加工要求低，并且装配简单的安全的新型电磁阀。
为了克服背景技术中存在的缺陷，本发明解决其技术问题所采用的技术方案是：一种新型电磁阀，包括壳体，所述壳体外部套设有电接头注塑件，所述壳体内依次设置有线圈、线圈支架和铁芯，所述铁芯与壳体活动连接，所述线圈固定在线圈支架上，所述线圈支架贴合铁芯外壁设置，所述铁芯内通过弹性机构固定有衔铁，所述衔铁外壁与铁芯内壁间留有空隙，所述铁芯上设置有隔磁槽，所述铁芯下部外壁上设置有第一凹槽和第二凹槽，所述第一凹槽内卡设有第一密封圈，所述第二凹槽内卡设有第二密封圈；所述铁芯上设置有多个进气孔，所述衔铁长于进气孔设置，所述衔铁中部固定有导套，所述铁芯底部设置有限位槽，所述限位槽内设置有喷嘴，所述喷嘴顶部与限位槽上壁间设置有第一垫片，所述喷嘴顶部设置有第三密封圈，所述第三密封圈设置在出气孔四周；所述喷嘴通过紧固帽与铁芯底部活动连接。
在本发明的一个较佳实施例中，所述铁芯与壳体通过紧固件活动连接。
在本发明的一个较佳实施例中，所述铁芯下部直径依次递减。
在本发明的一个较佳实施例中，所述进气孔设置在铁芯底部。
在本发明的一个较佳实施例中，所述第一凹槽的直径大于第二凹槽的直径。
在本发明的一个较佳实施例中，所述导套为非导磁材质。
本发明的有益效果是：
1、本发明采用铁芯与壳体通过紧固件活动连接，方便后续检修时拆卸方便；
2、本发明采用铁芯上设置有隔磁槽，通过隔磁槽来改变磁场，产生隔磁效应，从而达到在衔铁上产生径向力和轴向力，达到比例电磁铁效果；
3、本发明采用铁芯下部直径依次递减的设计，能够防止密封圈装配时不被损坏，有效地降低了部件损坏率，提供了生产效率，降低了生产成本；
4、本发明衔铁中部固定有非导磁导套，一方面防止衔铁在侧偏的时候，由于单侧径向空气余隙减小会使得单侧径向力过大导致衔铁和导套贴合产生的摩檫力阻碍衔铁运动；另一方面利用衔铁上的套筒来做衔铁运动的导向；
5、本发明采用喷嘴顶部与限位槽上壁间设置有第一垫片，无需根据各种要求调整部件的加工尺寸，能够满足工作对衔铁顶部与衔铁间空隙的不同要求；
6、本发明采用喷嘴通过紧固帽与铁芯底部活动连接，在需要拆卸喷嘴进行重新装配时，拆卸相对简便，并且能够重复利用。
