Public flue with variable-pressure anti-backflow function
A public flue with a variable-pressure anti-backflow function comprises a main flue pipe, the main flue pipe is a uniform-section pipeline and comprises a mounting wall, a through hole is formed in the mounting wall, an exhaust channel used for communicating the main flue pipe with an external flue is arranged in the through hole, the exhaust channel comprises an air inlet and an air outlet, and the air inlet is communicated with the air outlet. The plurality of through holes are formed in the longitudinal direction at intervals; the flue pressure changing device further comprises a flue pressure changing piece, the flue pressure changing piece penetrates through the through hole and is connected to the installation wall, the flue pressure changing piece is provided with a transverse flue pressure changing plate, and the plane where the flue pressure changing plate is located is not higher than the plane where the lowest point of the air outlet is located. Compared with the prior art, the public flue has the advantages that on the basis that the public flue is provided with the uniform-section flue, the flue variable pressure plate is arranged, so that the flue gas backflow prevention effect is further improved.
一种具有变压防倒灌功能的公用烟道，包括主烟道管，所述主烟道管为等截面管道，其包括安装壁，所述安装壁上设有贯穿孔，所述贯穿孔内设有用于连通主烟道管和外部烟道的排气通道，所述排气通道包括进气口和出气口，所述贯穿孔有多个，多个贯穿孔沿纵向方向间隔设置；还包括烟道变压件，所述烟道变压件穿过贯穿孔并连接于安装壁上，烟道变压件设置有横向的烟道变压板，烟道变压板的所在平面不高于出气口的最低点的所在平面。与现有技术相比，本发明的公用烟道在具有等截面烟道的基础上，通过设置烟道变压板，进一步提高了防烟气倒灌效果。
