Abstract

本实用新型公开了一种直通电磁阀，包括阀体和设置在阀体上的内套，内套外设置有电磁线圈，内套中设置有导磁芯和铁芯，导磁芯和铁芯之间设置有弹簧，铁芯的底部固定连接有用于控制水流通断的密封圈，特点是导磁芯固定设置在内套的上端部，导磁芯的底部开设有与铁芯的顶端相适配的凹槽，当导磁芯和所述的铁芯吸合时，铁芯的顶端伸入所述的凹槽内；优点是可有效增加电磁吸力，使得导磁芯和铁芯之间的吸合更平稳，在同等电磁吸力的情况下，可将电磁线圈的线径减小，用量减少，从而提高电磁阀的工作寿命和可靠性，同时也降低了电磁阀的能耗。

Description

一种直通电磁阀
技术领域
本实用新型涉及一种电磁阀，尤其是涉及一种直通电磁阀。
背景技术
现有的净水机、饮水器、空调阀等设备用于控制水流通断的直通电磁阀，通常由通电电磁线圈产生的电磁力来维持阀的开启，整个过程中必须保持电源处于接通状态，由于电磁阀内的密封件是随铁芯抬起而联动抬起，与普通电磁阀先导式原理不同，此类电磁阀要求电磁线圈的吸力足够大。目前大多数的直通电磁阀包括设置在内套中的导磁芯、弹簧和铁芯，弹簧设置在导磁芯和铁芯之间，导磁芯是靠弹簧顶在内套上端部的，在电磁阀吸合时，导磁芯和铁芯的吸合不够平稳，会产生噪音。
发明内容
本实用新型所要解决的技术问题是提供一种导磁芯和铁芯能够平稳吸合的直通电磁阀，可有效避免噪声的产生。
本实用新型解决上述技术问题所采用的技术方案为：一种直通电磁阀，包括阀体和设置在阀体上的内套，所述的内套外设置有电磁线圈，所述的内套中设置有导磁芯和铁芯，所述的导磁芯和所述的铁芯之间设置有弹簧，所述的铁芯的底部固定连接有用于控制水流通断的密封圈，所述的导磁芯固定设置在所述的内套的上端部，所述的导磁芯的底部开设有与所述的铁芯的顶端相适配的凹槽，当所述的导磁芯和所述的铁芯吸合时，所述的铁芯的顶端伸入所述的凹槽内。
所述的凹槽的侧壁上设置有第一导向斜面，所述的铁芯的顶端设置有与所述的第一导向斜面相适配的第二导向斜面，有效引导磁芯和铁芯之间吸合。
所述的内套上设置有环形定位台阶，所述的导磁芯压在所述的环形定位台阶上。
与现有技术相比，本实用新型的优点在于导磁芯固定设置在所述的内套的上端部，导磁芯的底部开设有与铁芯的顶端相适配的凹槽，导磁芯和铁芯吸合时，铁芯的顶端伸入所述的凹槽内，可有效增加电磁吸力，使得导磁芯和铁芯之间的吸合更平稳，在同等电磁吸力的情况下，可将电磁线圈的线径减小，用量减少，从而提高电磁阀的工作寿命和可靠性，同时也降低了电磁阀的能耗。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
以下结合附图实施例对本实用新型作进一步详细描述。
如图所示，一种直通电磁阀，包括阀体1和设置在阀体1上的内套2，内套2外设置有电磁线圈3，内套2中设置有导磁芯4和铁芯5，导磁芯4和铁芯5之间设置有弹簧6，铁芯5的底部固定连接有用于控制水流通断的密封圈7，导磁芯4固定设置在内套2的上端部，内套2上设置有环形定位台阶21，导磁芯4压在环形定位台阶21上，导磁芯4的底部开设有与铁芯5的顶端相适配的凹槽41，当导磁芯4和铁芯5吸合时，铁芯5的顶端伸入凹槽41内，凹槽41的侧壁上设置有第一导向斜面411，铁芯5的顶端设置有与第一导向斜面411相适配的第二导向斜面51。
