Ventilation engineering is the equipment that needs to be prepared for factories, warehouses, hotels, etc. the ventilation engineering is mainly responsible for ventilation, induced air, exhaust, dust removal and other work. The fan and air conditioning commonly seen in the kitchen exhaust hood of Jinan hotel are actually one kind of ventilation engineering.

2. The rotating parts of the tuyere should be flexible, the blades or inserts should be straight, the inner distance of the blades should be uniform, the expansion ring and adjustment of the diffuser should be coaxial, the axial spacing distribution should be uniform, the opening and closing of the blades should be complete, the direction of the air defense airtight valve should be accurate with the shock wave, and it should not be installed reversely. The blades of smoke exhaust hood in Jinan hotel kitchen should be fully opened or closed, which can not be used to adjust the air volume.
3. The manufacturing of all kinds of valves shall be firm, the adjustment and braking device shall be accurate, flexible and reliable, and the opening and closing direction of the valve shall be indicated. The thickness of fire damper shell shall be greater than or equal to 2mm, and the material selection shall meet the requirements of GB 50243-97.
4. Rubber type is selected for flexible short pipe civil air defense virus filtration system, and fire-proof canvas is selected for others. All hangers, supports and brackets shall be flat and firm, with full weld seam and even arc of hoop. 上一篇：通风管道安装应满足哪些条件？
