    For range hoods, check valves must be installed, so as to effectively prevent the backflow of oil fumes in the public flue and make the kitchen free of oil smoke odor. The function of the check valve is to prevent the backflow of oil fumes, and the design only allows the flow in one direction, preventing the air flow in the opposite direction. For range hoods, it is usually necessary to use 2 check gates.

    Range hood check valve installation steps.

    1. The kitchen auxiliary flue must be retained. Each kitchen has a flue, and at the same time, the flue is also divided into main and secondary, the main flue runs through the entire building, and the auxiliary flue is relatively independent.

    Generally, the oil smoke in the home will first go to the auxiliary flue, and then enter the main flue through the hole in the partition, so as to ensure that the oil smoke of each household is isolated. However, if the secondary flue is directly connected to the main flue, the pressure will be too low, resulting in back-up or cross-smoke.

    Second, pay attention to the details of installation and construction.

    1. It is very important to choose the location where the range hood is installed, and the shorter the pipe, the better. Some owners will stretch the pipe longer for the sake of aesthetics, so that after turning off the range hood, a lot of oil smoke will accumulate in the pipe and cannot be discharged, and then poured back indoors. The flatbed body design is simple and stylish.

    However, it is not suitable for frying, stir-frying, cooking, and frying cooking forms, because the smoke hood is too shallow or there is no smoke hood at all, and the oil smoke that cannot be smoked away is serious and spreads seriously. To solve this problem, it is recommended to change to a deep hood type range hood.

    2. In order not to destroy the original main and auxiliary flues, the opening direction of the range hood can not be changed at will, and it must be played in the auxiliary flue.

    3. The kitchen smoke exhaust and anti-reverse valve should be replaced frequently. If the auxiliary flue has been removed, or if it is better to prevent the back-up of smoke, then use the flue check valve. Under normal circumstances, the effect of the check valve of the range hood is not very obvious, and the installation of the check valve in the flue can protect the range hood, so that the smoke in the flue will not be poured into the pipe and the range hood.

    However, after installing the check valve, it should be cleaned regularly, otherwise the check valve will be open and lose its effect, and the flue check valve should be replaced once every two years or so.

    About range hood check valve.

    The range hood check valve is also called the name of air outlet, exhaust outlet and air hood, etc., it is the range hood comes with, the bottom is fixed on the top of the range hood with screws, and the upper part is connected to the plastic telescopic smoke pipe.

    There are generally two baffles inside the range hood check valve, but because the traditional smoke check valve has the problem of the baffle is not tightly sealed (no matter how high-end the hood), there is a problem of the range hood smelling back.

    The range hood check valve of different brands or models of hoods is likely to be different, and there is no unified industry standard. However, the caliber of the plastic retractable smoke pipe is basically divided into four types: 18cm, 17cm, 16cm and 15cm.

    The check valve can be installed directly to the air outlet of the range hood.

    The length of the smoke exhaust pipe is calculated as the nearest straight line distance from the top of the smoke machine to the public flue mouth, and it should be noted that the vertical length (the length of the pipe pipe to the transverse direction of the smoke pipe is also added), and the length attached to the general smoke machine does not exceed 2000mm, which is enough to meet the normal needs. If this length is not enough, and you want to ensure the smoke exhaust effect, you can install a relay device between the two smoke exhaust pipes, which is an air supply device to ensure the overall exhaust capacity.

    Hello! The check valve installed vertically on the new return scale of the range hood can still be used when removed. The check valve on the range hood is generally not sealed, and it is useless, and it will still pour smoke.

    For example, the check valve on the Fotile range hood is not sealed, and it is still sticky to the oil stain after a long time, and sometimes the range hood can only be opened after a while. Therefore, Fotile has produced another check valve, and many range hoods have dismantled most of the leaks after installing the check valve.
