Description

一种换向阀
技术领域
本发明涉及一种用于钢包烘烤设备上的换向阀,尤其涉及一种换向阀。
背景技术
目前冶金行业蓄热式钢包烘烤装置,为了尽可能的提高热效率,烘烤器都采用了不同形式的排烟余热回收装置,以提高助燃空气的温度和降低烟道的排烟温度,减少烘烤器的排烟热损失。从钢包内返回溢出的余热,通过竖烟道,进入换向阀,可将助燃空气预热至300-500℃左右。这样能够节省能源,增加热效率。换向阀就是利用烘烤废气余热与助燃空气进行热交换,达到预热助燃空气的目的。一般多采用空气及烟气同步换向,其换向***结构复杂,特别是燃气含杂质度高、纯度低时,容易堵塞,不易清理,保养困难等缺点。
发明内容
本发明为了解决以上问题提供了一种换向阀,结构简单合理,不易堵塞,方便清理,本发明实用性强,尤其适合低热值、低纯度燃气介质燃烧的换向阀。
本发明的技术方案是:所述的换向阀包括阀体、进气腔、出气腔、密封体、密封盘和连杆机构,所述的密封体固定设置在密封盘上,所述的密封盘上设有球形卡槽锁紧机构,所述的密封体设置在进气腔的进气口,所述的连杆机构包括伸缩压杆和驱动机构,所述的伸缩压杆前端设有与球形卡槽锁紧机构相适配的球状卡块。
本发明通过气缸的伸缩动作控制连杆,带动密封盘来快速实现烘烤器的换向,结构简单,操作方便,换向腔内部不易堵塞,提高了工作效率,尤其适合低热值、低纯度燃气介质的燃烧,减少了维护和生产成本,清理方便。
附图说明
图1是本发明的结构示意图。
图中1是阀体,2是进气腔,3是出气腔,4是密封体,5是密封盘,6是连杆机构。
具体实施方式
一种换向阀,所述的换向阀包括阀体1、进气腔2、出气腔3、密封体4、密封盘5和连杆机构6,所述的密封体4固定设置在密封盘5上,所述的密封盘5上设有球形卡槽锁紧机构,所述的密封体4设置在进气腔2的进气口,所述的连杆机构6包括伸缩压杆和驱动机构,所述的伸缩压杆前端设有与球形卡槽锁紧机构相适配的球状卡块。

Claims (1)
