Abstract

本实用新型公开了一种只用加一个瞬时脉冲电压后就能保持阀门开启或关闭的电磁阀。本电磁阀由阀体(1)、薄膜套(2)、动铁芯(8)、静铁芯(10)、线圈(4)和安装在静铁芯(10)顶端的永久磁铁(11)组成。这样,既延长了阀门的使用寿命又能节约电能。

Description

电磁阀
本实用新型属于一种电磁控制介质通、断的阀门。
现有的电磁阀由阀体、线圈、动铁芯、静铁芯、弹簧、薄膜套组成。当线圈通电形成的磁场吸起动铁芯,薄膜套也随之离开阀口,阀门开启,当线圈断电时,动铁芯在弹簧的弹力作用下,把薄膜套紧压在阀口上,阀门关闭。由于该电磁阀的线圈必须连续通电,才能维持阀门开启,所以耗电量大。
本实用新型的目的是提供一种通入瞬时电流后能保持阀门开启或关闭的电磁阀。
为达到上述目的,本实用新型的技术解决方案是:电磁阀由线圈4、静铁芯10、动铁芯8、弹簧9、薄膜套2、阀体1和安装在静铁芯10顶端的永久磁铁11组成。
由于本实用新型是在静铁芯的顶端安装一块永久磁铁,因此在线圈通以正向脉冲电压时,线圈产生的磁场增强了永久磁铁的磁场,使之产生足够的吸引力吸引动铁芯,此后不必再给线圈继续通电,永久磁铁也能牢牢地吸住动铁芯,从而保持阀门开启。
下面结合附图和实施例对本实用新型作进一步详细的描述。
附图为本实用新型电磁阀的结构示意图。
参照附图,图中标号分别是:1阀体,2薄膜套,3圆盘,4线圈,5导线,6辅阀口,7平衡孔,8动铁芯,9弹簧,10静铁芯,11永久磁铁。
附图所示的电磁阀,当通过导线5给线圈4加以正向脉冲电压时,线圈4产生的瞬时磁场增强了永久磁铁11形成的磁场,产生足够的电场力克服弹簧9弹力而吸引动铁芯8,动铁芯8离开辅阀口6,由于圆盘3上的平衡孔7小于辅阀口6的孔径,薄膜套2上腔的压力小于下腔进水口的压力所以隔膜2在此压力差作用下向上运动,打开阀口,阀门开启。此后,不必继续通电,水久磁铁11本身的磁场力,也能牢牢地吸住动铁芯8,而保持阀门开启。当线圈4通以反向瞬时脉冲电压时,线圈4产生的瞬时磁场减弱了永久磁铁11的磁场,动铁芯8在弹簧9的弹力作用下,离开静铁芯10,而将圆盘3和薄膜套2推向阀口,而关闭阀门。
