【技术实现步骤摘要】
单向流壁挂式新风机球阀结构
本技术涉及一种单向流壁挂式新风机,具体的说是单向流壁挂式新风机球阀结构,属于单向流新风机
技术介绍
目前,国内民用小型壁挂式单向流新风机组只能单方向送风或排风,不能同时切换室内外循环,在室外空气恶劣的情况下,机组净化效率降低,影响室内空气质量。因为新风机组是单向流,没有冷热交换功能,影响了室内温度的恒定,在室外温度过低时机组不能切换内循环造成机组结露现象,影响了机组的正常使用。
技术实现思路
本技术的目的在于克服上述不足之处,从而提供一种单向流壁挂式新风机球阀结构,能够实现室外进风及室内进风互相切换,同时充分考虑到机组左向安装与右向安装的循环风道布置,提高了使用范围,便于机组安装。按照本技术提供的技术方案,单向流壁挂式新风机球阀结构包括上阀体、下阀体和球阀体,其特征是:上阀体和下阀体上下对应连接成一体,上阀体和下阀体之间设有球阀安装腔,球阀安装腔内设有能够自由回转的球阀体,球阀体下端连接步进电机驱动端,步进电机工作时带动球阀体旋转;上阀体和下阀体前端分别设有上新风进口和下新风进口,上新风进口和下新风进口上下连接形成新风进风通道,新 ...
