Description

一种电磁阀
技术领域
本实用新型涉及一种电磁阀。
背景技术
电磁阀在暖通空调、制冷等涉及温度控制、调节的系统中的应用越来越广泛,而阀杆与阀芯脱离的电磁阀最为典型,该种电磁阀的的阀杆的顶端与电磁铁芯连接,下端作为顶杆,阀芯置于阀芯通道内,该通道内还设有弹簧,阀芯位于弹簧上,阀芯抵触在阀杆的下端,当电磁断电时,电磁内弹簧带动铁芯及阀杆向下运动,阀杆顶住阀芯向下运动,阀芯脱离阀口,电磁阀打开;反正,阀芯在其弹簧的弹力作用下,与阀口贴合,电磁阀关闭;这种电磁阀需要在阀芯通孔内设置弹簧,结构比较复杂,而且弹簧的要求比较高,且弹簧使用时间久内容易变形,严重影响阀芯与阀口间的密封性。还有现有的阀芯大多为铁球,阀口与其贴合处需要设置密封圈,由于阀口较小且处于阀座内部,密封圈往往很难安装。
实用新型内容
本实用新型的目的是提供一种结构简单、密封性能好的电磁阀。
本实用新型采用的技术方案是:一种电磁阀,包括阀座、阀杆、阀芯、进水口和出水口,所述阀座内设有阀口,所述阀杆置于阀口内,所述阀座顶部设有驱动阀杆上下运动的电磁执行部件,所述阀座底部设有阀芯通道,所述阀芯通道内填充有弹性橡胶垫,所述阀杆的底部伸入阀芯通道内并与阀芯固定连接。
本实用新型的阀杆与阀芯直接固定连接,并在阀芯通道内填充了弹性橡胶垫,该弹性橡胶垫起到托撑阀芯的作用,当电磁通电时,电磁铁芯带动阀杆向上运动,并带动阀芯向上运动,致使阀芯顶住阀口,电磁关闭;反之,当电磁断电时,电磁消失,铁芯在弹簧的作用下,带动阀杆向下运动,当阀芯顶住弹性橡胶垫后,阀芯与阀口离开,电磁阀关闭。本实用新型的整个运作过程恰与现有的相反。
为了使得阀芯与阀口间有很好的接触密封性,将阀芯设计为由弹性橡胶材料制成的球形结构,这样阀座口就可无需设置密封圈,阀芯本身亦起到密封圈的作用。
为了防止阀芯偏移,影响阀芯与阀口间的密封性,在弹性橡胶垫与阀芯接触处留有凹槽。
本实用新型的优点是:结构简单,密封性能好,节约成本。
附图说明
图1为本实用新型的整体结构示意图。
其中:1、阀座,2、阀杆,3、阀芯,4、进水口,5、出水口,6、阀口,7、电磁执行部件,8、阀芯通道,9、弹性橡胶垫,10、凹槽,11、铁芯。
具体实施方式
如图1所示,一种电磁阀,包括阀座1、阀杆2、阀芯3、进水口4和出水口5,在阀座内设置了阀口6,阀杆2置于阀口6内,在阀座1顶部设有驱动阀杆2上下运动的电磁执行部件7,在阀座1底部设有阀芯通道8,在阀芯通道8内填充有弹性橡胶垫9,阀杆2的底部伸入阀芯通道8内并与阀芯3固定连接;当电磁通电时,电磁铁芯11带动阀杆2向上运动,并带动阀芯3向上运动,致使阀芯3顶住阀口6,电磁关闭;反之,当电磁断电时,电磁消失,铁芯11在弹簧的作用下,带动阀杆2向下运动,当阀芯3顶住弹性橡胶垫9后,阀芯3与阀口6离开,电磁阀关闭。
为了使得阀芯3与阀口6间有很好的接触密封性,将阀芯3设计为由弹性橡胶材料制成的球形结构,这样阀口6就可无需设置密封圈,阀芯本身亦起到密封圈的作用。
为了防止阀芯3偏移,影响阀芯3与阀口6间的密封性,在弹性橡胶垫9与阀芯3接触处留有凹槽10。
