Variable pressure check valve for public flue
A variable pressure check valve for a public flue comprises a shell and a valve arranged in the shell, the shell comprises a kitchen range hood end and a flue stretching-in end, the kitchen range hood end is provided with an air inlet, the flue stretching-in end is provided with an air outlet, the opening direction of the air outlet is upward or obliquely upward, and the valve is arranged in the shell. A transverse flue variable pressure plate is arranged at the extending end of the flue, and the plane where the flue variable pressure plate is located is not higher than the plane where the lowest point of the gas outlet is located. Compared with the prior art, the variable-pressure check valve has the advantages that the flue variable-pressure plate is arranged, so that the effect of preventing smoke from flowing backwards is further improved.
一种用于公用烟道的变压止逆阀，包括外壳以及设于所述外壳内的阀门，所述外壳包括厨房烟机端和烟道伸入端，所述厨房烟机端设有进气口，所述烟道伸入端设有出气口，所述出气口的开口方向向上或倾斜向上设置，所述烟道伸入端上设置有横向的烟道变压板，所述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，本发明的变压止逆阀通过设置烟道变压板，进一步提高了防烟气倒灌效果。
