Brief introduction of lampblack pipeline
Oil fume pipeline is an important channel for family to exhaust oil fume, which is generally divided into indoor oil fume pipeline and outdoor oil fume pipeline. Indoor lampblack pipeline is relatively thin, generally installed on the pipeline of range hood, and at the same time, it can better eliminate lampblack. Outdoor oil fume pipeline is the main way for many families to exhaust oil fume, and its pipelines are relatively thick, such as white iron (galvanized steel) oil fume pipeline and Kurogane (iron) oil fume pipeline. Oil fume pipes are widely used in construction projects, such as restaurants, hotels, hotels, hospitals, factories, shopping malls, office buildings and so on.
Installation method of oil fume pipeline
First, the auxiliary flue must be preserved.
Every kitchen has a flue, and at the same time, the flue also has the main and auxiliary points. The main flue runs through the whole building and the auxiliary flue is relatively independent. Generally, the lampblack at home will go to the auxiliary flue first, and then enter the main flue through the hole in the partition, so as to ensure that the lampblack of every household is isolated. However, if the auxiliary flue is directly connected with the main flue, it will lead to the phenomenon of backward smoke or cross smoke due to too low pressure.
Second, the construction details should pay attention to the problem
First of all, it is very important to choose the installation position of the range hood. The shorter the pipe, the better. Some owners will pull the pipe longer for the sake of beauty. After turning off the range hood in this way, there will be a lot of oil smoke in the pipeline that can't be discharged and then poured back indoors. In addition, in order not to destroy the original main and auxiliary flue, its opening direction cannot be changed at will, and it must be drilled in the auxiliary flue.
Third, pay attention to safety when opening the window to smoke.
First of all, before opening a hole in a window or wall, it must be approved by the property; Secondly, pay attention to safety issues. Generally, the end of the exhaust pipe is metal. If the hole is too small, the metal heat transfer may cause the glass to burst and hurt pedestrians, and the smoke exhaust pipe will lead out of the window, and the strong north wind blowing head-on will lead to the backflow of oil smoke. It is best to extend the pipeline and nest it downward, so as to prevent rainwater from flowing into the pipeline when it rains.
Put the windshield outside. Four, check valve door often change.
If the auxiliary flue has been removed, or it is necessary to better prevent the flue gas from falling back, then use the flue check valve. In general, the function of the check valve of the range hood is not obvious, but installing the check valve in the flue can protect the range hood, so that the flue gas in the flue will not flow back to the pipeline and the range hood. However, after installing the check valve, it should be cleaned regularly, otherwise it will make the check valve open and lose its function. It is best to replace the flue check valve every two years or so.
Matters needing attention in installation of lampblack pipeline
The most important thing in the installation of oil fume pipeline is the sealing of the pipeline interface, and a fire card is set when necessary. Generally, the installation of oil fume pipes is carried out by professional decoration personnel. Consumers should never install it separately if they don't know much about it, so as to avoid unsightly installation and unnecessary trouble.
1 First of all, it is necessary to check whether there is a downward movement of the ceiling at the mouth of the lampblack pipeline, so as to reserve the upper space and position.
2. Pay attention to plug the gap at the smoke outlet when burying the smoke exhaust pipe to ensure that it is firm and does not fall off.
3. Before the ceiling, the exhaust pipe of the range hood is embedded in the upper part of the ceiling, and the exposed position of the exhaust pipe on the ceiling needs to be determined according to the design drawings of the cabinet.
You need to refer to the style of the hood. Generally speaking, the pipe of the European hood is in the middle position, while the smoke outlet of the sergeant hood is on one side of the hood. These conditions will affect the position of the reserved opening. 4. If the cooker is placed on the balcony side, we need to pay attention to whether the oil smoke pipe passes through the lintel of the building. In principle, the general property management department does not allow us to make holes in the smoke exhaust pipe on the lintel. This treatment method can not only avoid considering the distance between the oil fume nozzle and the wall, but also avoid that the distance between the oil fume nozzle and the wall is greater than the depth of the hanging cabinet, which will affect the installation of the hanging cabinet, and also avoid that there is a horizontal smoke exhaust pipe at the top of the hanging cabinet after installation, which will affect the appearance.
5. In this way, it is inevitable that the pipeline will run up and down in the exposed part of the ceiling and the upper part of the range hood. You can design a protection board to decorate it according to the position and height of this oil fume pipeline.
You can design a cover plate for decoration according to the position and height of the oil fume pipeline.
