1.变压式：这种99无码熟妇丰满人妻啪啪将各层的烟道做成不同的截面形式，下层烟道通过主次烟道排气，而靠近屋面的烟道如同单烟道的作用，直接将油烟排入烟道排出。

　　1. transformer: this pipeline flue of each layer made of different section forms, the lower the flue through primary and secondary flue gas, and close to the roof like a single flue flue, directly discharged into the flue exhaust fumes.

　　原理：山东通风99无码熟妇丰满人妻啪啪加工通过改变烟道的截面形式，利用烟气流动的各种物理规律，使气流保持向上的运动，大程度防止烟气倒灌和互串。

　　Principle: by changing the cross section form of the flue gas, using the various physical laws of the smoke flow, the airflow can keep upward movement, so as to prevent smoke from flowing backward and crossing each other to the greatest extent.

　　2.单烟道式：这种99无码熟妇丰满人妻啪啪由一个简单的矩形烟管构成，垂直穿越各层住宅，在每层住宅中留有一个连接抽油烟机的进风口，底层由一个补风口补气。

　　2. single flue type: this pipeline consists of a simple rectangular smoke pipe, vertical through each layer of residential, in each layer of the house, there is an air intake hood to connect the hood, and the bottom is filled by an air supply.

　　原理：各层烟气在抽油烟机的推动下，将油烟排入烟道中，由于烟气温度的作用，在烟道中产生上升浮力，从出屋面的出风口将烟气排出。

　　Principle: the smoke of each layer is pushed into the flue under the drive of the range hood, and the rising buoyancy is generated in the flue due to the function of the flue gas temperature, and the flue gas is discharged from the air outlet of the roof.

　　3.止逆阀式：止逆阀式烟道则是在单管烟道上的各层进风口处，加装一个兼有抽油烟机接口作用的复杂防气流逆行的止逆阀，迫使烟气向烟道单向运动，从而解决烟气互串的问题。

　　3. check valve type: check valve type flue is each layer in a single tube flue of the air inlet, with a combination of lampblack machine interface complex anti retrograde flow check valve, forcing the smoke to the flue way, so as to solve the problem of flue gas on each other.

　　4.主次式：这种99无码熟妇丰满人妻啪啪由一个简单的矩形烟管构成，垂直穿越各层住宅，在每层住宅中留有一个连接抽油烟机的进风口，底层由一个补风口补气。

　　4. primary and secondary style: this pipeline consists of a simple rectangular smoke pipe, vertical through each layer of residential, in each layer of the house, there is an air intake hood to connect the hood, and the bottom is filled by an air supply.

　　原理：各层烟气在抽油烟机的推动下，将油烟排入烟道中，由于烟气温度的作用，在烟道中产生上升浮力，从出屋面的出风口将烟气排出。

　　Principle: the smoke of each layer is pushed into the flue under the drive of the range hood, and the rising buoyancy is generated in the flue due to the function of the flue gas temperature, and the flue gas is discharged from the air outlet of the roof.
