As we all know, the kitchen is the most annoying place for cooking fumes. Everyone will install a range hood at home, so they won't be choked by cooking fumes. Flue has also become an indispensable decorative equipment in large kitchen equipment, and its function is to discharge oil smoke through the flue. So what is the installation method of lampblack pipeline? What should I pay attention to when installing? Let's take a look at the installation of oil fume pipes together.

Brief introduction of oil fume pipeline

Oil fume pipeline is an important channel for families to remove 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, while better eliminating lampblack. Outdoor oil fume pipeline is the main way for many households to remove oil fume, and its pipelines are relatively thick, generally including white iron (galvanized steel) oil fume exhaust pipeline and Kurogane (iron) oil fume exhaust 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

1. Auxiliary flue must be kept

Every kitchen has a flue, and at the same time, there are main flue 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 auxiliary flue first, and then enter the main flue through the hole in the partition, so as to ensure that the lampblack in each household is isolated. However, if the auxiliary flue is directly connected to the main flue, it will lead to the phenomenon of inverted smoke or cross smoke due to too low pressure.

Second, pay attention to the construction details

First of all, it is very important to choose the installation location of the range hood. The shorter the pipe, the better. Some owners will pull the pipes longer for the sake of beauty. In this way, after turning off the range hood, there will be a lot of oil smoke in the pipes 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 can not be changed at will, so it must be played in the auxiliary flue.

Third, pay attention to the safety of smoke exhaust from windows

First, you must get the consent of the property before opening holes in windows or walls; 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 burst and hurt pedestrians, and the smoke exhaust pipe leads out of the window, and the strong north wind blowing against it will lead to oil smoke backflow. It's best to extend the pipeline and then nest it down, so as to avoid rainwater from flowing into the pipeline when it rains, and keep the windshield outside.

iv. frequent replacement of non-return valve

if the auxiliary flue has been removed, or it is necessary to prevent smoke from pouring out, then use the flue non-return valve. Under normal circumstances, the check valve effect of the range hood is not obvious, but installing the check valve in the flue can protect the range hood, so that the smoke in the flue will not flow backwards into 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 effect, and it is best to replace the flue check valve every two years or so.

Precautions for the installation of oil fume pipes

The most important part of the installation of oil fume pipes is the sealing of pipe joints and the setting of fire prevention cards at special needs. Generally, the installation of oil fume pipes is carried out by professional decorators. Consumers should never install them alone if they don't know much about them, so as to avoid unsightly installation and unnecessary troubles.

1. First of all, we need to check whether there are conditions for the ceiling to move down to reserve space and position in the upper part.

2. When embedding the smoke exhaust pipe, pay attention to seal the gap at the smoke outlet and ensure that it is firm and does not fall off.

3. Before the ceiling, the smoke exhaust pipe of the hood should be embedded in the upper part of the ceiling. It is necessary to determine the position of the exposed mouth of the smoke exhaust pipe on the ceiling according to the design drawings of the cabinet, and also refer to the style of the hood. Generally speaking, the pipe of the European hood is in the middle position, while the smoke exhaust nozzle of the sergeant hood is on one side of the hood. These conditions affect the position of the reserved opening.

4. If the cooker is placed on the side of the balcony, 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 punch holes through the smoke exhaust pipe in the lintel. This treatment method can not only avoid considering the distance between the oil fume pipe mouth and the wall, but also avoid the influence on the installation of the hanging cabinet because the distance between the oil fume pipe mouth and the wall is greater than the depth of the hanging cabinet, and also avoid the influence on the appearance because there is a section of horizontal smoke exhaust pipe at the top of the hanging cabinet after installation.

5. This method will inevitably lead the pipeline up and down at the exposed part of the ceiling and the upper part of the hood. You can design a cover plate according to the position and height of this oil fume pipeline to decorate it.
