通风管道在日子中起到很重要的作用，一些油烟的扫除就全赖它了，下面就给我们解说一下通风管道的装置注意事项。

Smoke pipe plays a very important role in the day, some of the oil smoke sweeping depends on it, the following will explain to us the smoke pipe device attention.

1、副烟道保存：每家的厨房里都有烟道，一起烟道也有主副之分，主烟道贯穿整个楼体，而副烟道是不一样的。一般家里的油烟会先到副烟道里，然后再通过隔板上的孔进入主烟道，这样可保证每户的油烟是阻隔开来的。而假如将副烟道直接连接主烟道，就会因为压力过低而导致倒烟或串烟现象。

1. Subflue Preservation: Every kitchen has a flue, a flue also has the main and secondary points, the main flue throughout the building, and the subflue is different. Generally, the lampblack in the home will go into the sub-flue first, and then enter the main flue through the holes in the partition, so as to ensure that each household lampblack is isolated. If the auxiliary flue is directly connected to the main flue, the pressure will be too low and lead to backflue or string smoke phenomenon.

2、施工细节要留意：挑选抽油烟机装置的方位十分重要。管道越短越好。一些业主会为了漂亮，把管道拉得比较长，这样一来，关掉油烟机后，管道里还会集聚许多油烟排不出去，再倒回室内。别的，为了不损坏原有的主副烟道，其开口方向不是随意能够改的，必定要打在副烟道里边。

2, attention should be paid to the construction details: choosing the location of the hood is very important. The shorter the pipeline, the better. Some owners will stretch the pipes longer for the sake of beauty, so that after switching off the lampblack machine, a lot of lampblack will accumulate in the pipes and then pour back into the room. In addition, in order not to damage the original main and auxiliary flue, its opening direction is not optional can be changed, must hit in the secondary flue inside.

3、窗户排烟留意安： 一些人为了避免串烟问题，放弃原有烟道，直接在窗户上开孔排烟，这样做是能够的，但有几点需求留意。在窗户或墙面开洞之前必定要通过物业的赞同；一般排烟管末端是金属材质的，假如开的洞太小，金属传热或许会使玻璃迸裂，伤及行人，且烟管通向窗外，强劲的冬风对着吹会导致油烟倒灌。主张将管道伸出去今后把管道往下窝，这样还能够避免下雨时雨水流进管道，并把风挡在外面。

3. Window smoke safety: Some people in order to avoid the problem of smoke strings, give up the original flue, directly in the window hole smoke exhaust, this is possible, but there are a few points to pay attention to. First of all, before the window or wall openings must be approved by the property; generally, the end of the smoke pipe is made of metal, if the hole is too small, metal heat transfer may cause glass bursting, injuring pedestrians, and the smoke pipe to the window, strong winter wind blowing against the oil smoke will cause backfilling. It is advocated that the pipe should be stretched out and the pipe should be lowered to its nest so as to avoid rainwater flowing into the pipe when it rains and keep the wind out.

4、止逆阀门勤替换：假如现已把副烟道撤除，或是需求避免倒烟的作用更好，那么运用烟道止逆阀。一般情况下，油烟机的止逆阀作用不是很明显，而在烟道装置止逆阀能够保护油烟机，使烟道里的烟不会向管道和抽油烟机内倒灌。不过，装置止逆阀后要定时清洗，不然会使止逆阀呈打开状况，失掉作用，而且烟道止逆阀主张好两年左右就替换一次。

4. Check valve replacement frequently: If the sub-flue has been removed, or the need to avoid the role of smoke is better, then the use of flue check valve. Generally speaking, the function of the check valve of the lampblack machine is not obvious, but the check valve of the flue device can protect the lampblack machine, so that the smoke in the flue can not be poured back into the pipe and the lampblack machine. However, after installing the check valve, it should be cleaned regularly, otherwise the check valve will open and lose its function, and the flue check valve should be replaced about two years.

通风管道在日常日子中也会起到许多的作用，在它的规划方面也是有考究的，下面就给我们详细的介绍一下它的规划准则。

Ventilation pipes also play a lot of role in daily life, in its planning is also fastidious, the following gives us a detailed description of its planning guidelines.

1、体系的区分排烟体系防烟分区区分应结合建筑防火分区来考虑，做到既有利于地下室通风体系兼作排烟体系，又不会呈现排烟风管跨过枋火分区现象。所以运用一套风管时体系应满意平常排风与火灾时排烟要求。

1. The smoke control zoning of the smoke exhaust system should be considered in combination with the fire protection zoning of the building. It is not only conducive to the ventilation system of the basement and the smoke exhaust system, but also does not show the phenomenon that the smoke exhaust duct crosses the fire zoning. Therefore, when using a set of air pipes, the system should be satisfied with the exhaust requirements of ordinary exhaust and fire.

2、地下室通风方法合理安置排风管及排风口，平常排风用，火灾时兼作排烟风管及排烟口;地下一层考虑由车道自然进风，其它层由平常送风体系兼作火灾时补风体系。每个排风、排烟及送风体系应设置竖井，进风口应设在地上洁净处，若能与地下主楼有必定间隔更好，其受火灾气影响会小;若能与地上主楼有必定间隔更好，其受火灾烟气影响会小，排风口方位应高于附楼层面， 以削减排风对地上环境影响。

2. The ventilation method of the basement is to arrange the exhaust pipe and outlet reasonably, which is usually used for ventilation, and is used as both the exhaust pipe and the exhaust outlet in case of fire; the natural air intake of the driveway is considered in the first floor of the basement, and the supplementary air system in case of fire is used in the other layers. Each exhaust, smoke exhaust and air supply system should be equipped with a shaft, air inlet should be located in the ground clean place, if there is a definite interval with the underground main building is better, it will be less affected by fire gas; if there is a definite interval with the ground main building is better, it will be less affected by fire smoke, exhaust outlet should be higher than the level of the attached floor, in order to reduce the exhaust air pairs. Environmental impact.

3、排风、排烟及送风风机选型排风、排烟风机可选离心风机或者高温轴流风机。一般离心风机即可满意排风排烟要求，但大风量离心风机只能装置在地上，占地较大，需求较大机房，高温轴流风机为消防专用风机，也能满意在280℃烟温下运转30分钟的要求，而高温轴流风机体积小，一般可吊装，若设机房面积也小，实际工程规划中，往往选用高温轴流风机排烟。

3. Centrifugal fan or high temperature axial fan can be selected for exhaust, smoke exhaust and fan selection. General centrifugal fans can satisfy the requirements of exhaust air and smoke, but high-volume centrifugal fans can only be installed on the ground, occupying a larger area, the need for a larger machine room, high-temperature axial-flow fans for fire protection special fans, can also satisfy the requirements of operating at 280 C for 30 minutes, and high-temperature axial-flow fans are small in volume, generally can be hoisted, if set up room surface. In addition, the high temperature axial fan is often used for smoke extraction in actual engineering planning.
