专注通风管道加工·排烟罩

1、 The installation method of smoke exhaust pipes should be correct. The owner is concerned about the odor in the flue at home and does not know the reason. Sometimes this is due to errors left during the construction process. So what issues should owners pay attention to during the construction process?

1.需要保留辅助烟道  每个厨房都有一个烟道，同时烟道又分为主烟道和辅助烟道。主烟道贯穿整个建筑，辅助烟道相对独立。一般家里的油烟会进入辅助烟道，再通过隔板上的孔进入主烟道，可以保证每户的油烟都被隔离。但如果辅助烟道直接与主烟道相连，则会因压力低而出现倒烟或串烟现象。

1. It is necessary to retain auxiliary flue. Each kitchen has a flue, and the flue is divided into main flue and auxiliary flue. The main flue runs through the entire building, while the auxiliary flue is relatively independent. Generally, the cooking fumes in a household enter the auxiliary flue and then enter the main flue through the holes on the partition, ensuring that each household's cooking fume is isolated. However, if the auxiliary flue is directly connected to the main flue, there may be smoke inversion or string due to low pressure.

2.注意施工细节  ，油烟机的安装位置选择非常重要。管子越短越好。为了美观，有些业主会把水管拉得更长。这样一来，关掉油烟机后，会有大量的油烟堆积在管道里，无法排出，然后倒回室内。另外，为了不损坏原有的主辅烟道，不能随意改变开启方向，需要在辅烟道内打。

 

2. Pay attention to the construction details. Firstly, the selection of the installation position for the range hood is very important. The shorter the pipe, the better. For the sake of aesthetics, some homeowners may pull the water pipes longer. In this way, after turning off the range hood, a large amount of oil fumes will accumulate in the pipeline, which cannot be discharged and then return to the room. In addition, in order not to damage the original main and auxiliary flue, the opening direction cannot be changed arbitrarily, and it is necessary to open it inside the auxiliary flue.

3.从窗户排烟时要注意平安

3. Pay attention to safety when smoking from windows

为了避免烟雾问题，一些业主放弃了原有的济南厨房排烟管，直接在窗户上开孔排烟。这个可以，但是有几点需要注意。

In order to avoid smoke issues, some homeowners have abandoned the original Jinan kitchen smoke exhaust pipes and directly opened holes in the windows for smoke exhaust. This is fine, but there are a few points to note.

，在开窗或开墙前需要征得物业的同意;其次，注意问题。一般排烟管的末端是金属的。如果孔太小，金属传热可能导致玻璃破裂，伤害行人。而且烟管引出窗外，强劲的北风迎面吹来，会导致油烟回流。尽量把管子加长再嵌套下去，以免下雨时雨水流入管子，挡风玻璃留在外面。

Firstly, it is necessary to obtain the consent of the property before opening windows or walls; Secondly, pay attention to the issue. The end of a typical smoke exhaust pipe is made of metal. If the hole is too small, metal heat transfer may cause glass breakage and harm pedestrians. Moreover, the smoke pipe leads out of the window, and a strong north wind blows head-on, which can cause oil fumes to flow back. Try to lengthen and nest the pipes as much as possible to prevent rainwater from flowing into the pipes and leaving the windshield outside when it rains.

4.经常更换止回阀门  如果辅助烟道已拆除，或防排烟效果较好，则使用烟道止回阀。一般情况下，油烟机的逆止阀作用不明显，但在烟道内安装逆止阀可以保护油烟机，使烟道内的烟气不会倒流到管道和油烟机内。但止回阀安装后要定期清洗，否则止回阀会打开失效，烟道止回阀每两年左右更换一次。

4. Regularly replace the check valve. If the auxiliary flue has been removed or the smoke control effect is good, use the flue check valve. In general, the check valve of the range hood is not effective, but installing a check valve in the flue can protect the range hood from backflow of smoke into the pipeline and range hood. But the check valve should be cleaned regularly after installation, otherwise it will open and fail. The flue check valve should be replaced every two years or so.
