Description

一种通过电磁铁控制的排烟阀
技术领域
本发明涉及一种通过电磁铁控制的排烟阀，属于烟道排烟技术领域。
背景技术
排烟阀是安装在机械排烟系统各支管端部处，平时呈关闭状态并满足漏风量需求，排烟时通过手动或者电动打开，其排烟作用。现在的排烟阀基本全是通过驱动装置自动打开的，但是这种驱动装置的结构较为复杂。
发明内容
为了解决上述技术问题，本发明提供了一种通过电磁铁控制的排烟阀。
为了达到上述目的，本发明所采用的技术方案是：
一种通过电磁铁控制的排烟阀，包括阀体，所述阀体的排烟口处从上往下设置有若干叶片，所述叶片为铁叶片，所有叶片盖住排烟口，所述叶片与垂直面之间具有夹角，所述叶片上设置有横向的轴孔，所述轴孔内穿有转轴，所述转轴的两端设置在阀体的内部上，所述转轴将叶片分为上叶片和下叶片，所述下叶片的重量大于上叶片的重量，所述阀体内还设置有第一电磁铁和第二电磁铁，所述第一电磁铁位于叶片的上游，用以吸引上叶片，所述第一电磁铁到转轴的距离不小于上叶片的宽度，所述第二电磁铁位于叶片的下游，用以吸引下叶片，所述第二电磁铁到转轴的距离不小于下叶片的宽度。
所述阀体的排烟口为管状结构。
所述第一电磁铁为环形电磁铁，
所述第二电磁铁为环形电磁铁。
所述第一电磁铁的中心轴线、第二电磁铁的中心轴线以及排烟口的中心轴线在同一条直线上。
所述第一电磁铁的侧壁与阀体的侧壁帖靠，所述第二电磁铁的侧壁与阀体的侧壁帖靠。
本发明所达到的有益效果：本发明在排烟时，对第一电磁铁和第二电磁铁通电，用第一电磁铁吸引和第二电磁铁分别吸引上叶片和下叶片，使叶片打开，当停止排烟时，第一电磁铁和第二电磁铁断电，上叶片和下叶片在各自重量的作用下复位；本发明结构简单，成本低。
附图说明
图1为本发明的横截面结构示意图。
图2为本发明的纵截面结构示意图。
具体实施方式
下面结合附图对本发明作进一步描述。以下实施例仅用于更加清楚地说明本发明的技术方案，而不能以此来限制本发明的保护范围。
如图1和2所示，一种通过电磁铁控制的排烟阀，包括阀体，阀体的排烟口为管状结构，阀体的排烟口处从上往下设置有若干叶片，叶片为铁叶片，所有叶片盖住排烟口，叶片与垂直面之间具有夹角，叶片上设置有横向的轴孔，轴孔内穿有转轴，转轴的两端设置在阀体的内部上，转轴将叶片分为上叶片3和下叶片4，下叶片4的重量大于上叶片3的重量，阀体内还设置有第一电磁铁2和第二电磁铁1，第一电磁铁2和第二电磁铁1均为环形电磁铁，第一电磁铁2的侧壁与阀体的侧壁帖靠，第二电磁铁1的侧壁与阀体的侧壁帖靠，第一电磁铁2的中心轴线、第二电磁铁1的中心轴线以及排烟口的中心轴线在同一条直线上，第一电磁铁2位于叶片的上游，用以吸引上叶片3，第一电磁铁2到转轴的距离不小于上叶片3的宽度，第二电磁铁1位于叶片的下游，用以吸引下叶片4，第二电磁铁1到转轴的距离不小于下叶片4的宽度。
上述的排烟阀，在在排烟时，对第一电磁铁2和第二电磁铁1通电，用第一电磁铁2吸引和第二电磁铁1分别吸引上叶片3和下叶片4，使叶片打开；当停止排烟时，第一电磁铁2和第二电磁铁1断电，上叶片3和下叶片4在各自重量的作用下复位；本发明结构简单，成本低。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和变形，这些改进和变形也应视为本发明的保护范围。
