How to solve the odor of kitchen flue

You can choose to install a closed valve at the smoke outlet at home, so that under the action of the range hood valve and the closed valve, the oil fume can be prevented from flowing backwards.

Install a closed valve, which can only be used if the backflow is not particularly serious. This is because the oil fume at home will pass through the auxiliary flue first, and then enter the main flue through the small holes in the grid. This design is to ensure that the fumes of every household can be isolated. If the auxiliary flue at home is directly connected to the main flue, it may lead to smoke crosstalk or smoke inversion due to low pressure.

If the oil fume backflow is serious, it is best to install a check valve with better quality at home. Its working principle is that the flue gas does not flow downward after passing through the command valve, but flows upward in a straight line. In general, the function of the check valve of the range hood is not particularly 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.

If the smoke exhaust pipe is not well sealed, it is recommended to wrap it tightly with transparent tape. Due to the accumulation of grease, the movement of the baffle is limited, so it is recommended to replace or clean the check valve. Air leakage and odor caused by loose connection, falling off and fracture at both ends of the exhaust hose, so it is recommended to replace the exhaust hose. If there is a problem with the flue, it is recommended to find a property to solve it.
