专注通风管道加工·排烟罩

1、 The auxiliary flue must be reserved. Every kitchen has flue, and the flue also has main and auxiliary flue. The main flue runs through the whole building, while the auxiliary flue is relatively independent. Generally, the lampblack in the home will go to the secondary flue first, and then enter the main flue through the hole on the partition, which can ensure that the lampblack in each household is isolated. If the auxiliary flue is directly connected to the main flue, it will cause smoke inversion or string due to low pressure.

二、施工细节要注意，管道越短越好。另外，为了不破坏原有的主副烟道，其开口方向不是随意可以改的，一定要打在副烟道里面。

2、 Pay attention to the construction details. The shorter the pipeline, the better. In addition, in order not to damage the original main and auxiliary flue, the opening direction is not optional, and must be placed inside the auxiliary flue.

三、一些业主为了避免串烟问题，放弃原有烟道，直接在窗户上开孔排烟，这样做是可以的，但有几点需要注意。在窗户或墙面开洞之前一定要经过物业的同意；其次注意问题，一般排烟管末端是金属材质的，如果开的洞太小，金属传热可能会使玻璃炸裂，伤及行人，且烟管通向窗外，强劲的北风对着吹会导致油烟倒灌。更好将管道伸出去以后把管道往下窝，这样还可避免下雨时雨水流进管道，并把风挡在外面。

3、 In order to avoid the problem of smoke, some owners abandoned the original flue and directly opened holes in the windows to smoke. This is OK, but there are several points to be noted. First of all, the consent of the property must be obtained before opening the window or wall; Secondly, pay attention to the safety problem. Generally, the end of the smoke exhaust pipe is made of metal. If the hole is too small, the metal heat transfer may cause the glass to crack and hurt the pedestrian, and the smoke pipe leads to the outside of the window, and the strong north wind will cause the oil smoke to pour backward. It is better to stretch the pipe out and then nest it down, so as to prevent rain water from flowing into the pipe when it rains and keep the wind out.
