Range hoods are a must-have item in the kitchen. They can quickly remove the cooking waste from cooking stoves and the cooking fumes from the cooking process. However, if the kitchen fume ducts are not installed, even the best range hoods will not achieve good results. The flue installation work must be done in the kitchen. What are the kitchen flue installation methods ? What are the precautions when installing? Let's take a look!
Kitchen flue installation method :
1, a single flue
The single flue is made up of a simple rectangular smoke tube that runs straight through the layers of the dwelling. There is a single air intake that connects the range hoods in each floor. All layers of flue gas are discharged under the advancement of a range hood, and the smoke is discharged into the flue. The flue gas is discharged at the air outlet.
2, primary and secondary
The primary and secondary flue cross sections are composed of two side-by-side rectangular flue tubes, which pass straight through each floor. The secondary flue ducts have an air intake for connecting hoods in each floor of the residence. The secondary flue and main flue gas ducts must be separated from the air intakes. At intervals, there is an air inlet at the bottom of the main flue. After the hood is used to push the flue gas into the secondary flue, the range hood's propulsion force and the flue gas temperature buoyancy force are used to increase the smoke and then enter the main flue to discharge the roof.
3, transformer type
The variable-pressure flue duct will make the flue of each layer into different cross-section modes. After changing the cross-section mode of the flue, various physical rules of flue gas activity are used to keep the air flow upward.
4, check valve type
The non-return valve type flue is installed at the air inlet of each layer on the single-pipe flue, and a non-return valve with the interface of the range hood is provided to prevent the air flow from retrograde, so that the flue gas moves to the flue unidirectionally.
Kitchen flue installation notes :
1, vice flue must be retained
The main flues run through the entire building, while the auxiliary flues are relatively independent. In general, fumes from home are first entered into the vice flue and then into the main flue. If the secondary flue ducts are directly connected to the main flue duct, smoking or crosstalk may occur due to low pressure.
2, construction details should pay attention
The location of the hood is very important. It is recommended that the pipeline be as short as possible. Some owners will pull the pipeline long for beauty, so that when the hood is turned off, there are still soots that can gather in the pipeline, and then they are returned to the room.
3, window smoke attention safety
Some owners in order to avoid cross-talk problems, give up the original flue, directly in the window opening and exhaust, this can be done, but pay attention to the safety exhaust pipe end is a metal material, if the hole is too small, metal The heat transfer may cause the glass to burst and injure pedestrians, and the smoke pipes lead out of the window. The strong north wind blowing against the air will cause the fumes to fall back.
4, stop valve replacement
If the auxiliary flue has been dismantled, or if it is necessary to prevent the cigarette from falling, it is advisable to install a non-return valve on the flue so that the smoke in the flue will not be poured into the duct and the hood. After installing the non-return valve, it should be cleaned regularly, otherwise it will make the non-return valve open and lose its effect. The flue check valve should be replaced once every two years.
Concluding remarks: The above is the introduction of the kitchen flue installation methods and precautions for everyone, hoping to bring you help, if you need to learn more about the post-related knowledge, welcome to pay attention to this site information.
These beads are coated with a special coating during the manufacture of the glass beads. In the rainy and foggy weather, the moisture can not easily adhere on the surface of glass beads, so the effection on reflectivity caused by bad weather will be reduced. The granulometry of this type glass beads is the same as non-coated glass beads.
The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.
