Check valve manufacturers analyze the working principle of check valve
The principle of the check valve is very simple. As shown, the media flows in the specified direction. When the flow pressure exceeds the opening pressure of the check valve, the valve flap is pushed open under the fluid pressure, thereby connecting the circulation of the pipeline medium. On the contrary, when the pipeline medium flows backwards, under the push of fluid pressure, the valve flap is pressed on the valve body, and then the valve is closed, thereby cutting off the circulation of the pipeline medium. The greater the pressure of the backflow medium, the tighter the valve flap will be closed, and the better the sealing effect will be, which completely eliminates the possibility of medium backflow.
Check valves can be divided into three types according to different structural forms: lifting, rotating and butterfly. Lifting can be divided into vertical and horizontal, and its action method is to move along the shaft. multi-lobed. The way they work is to rotate against the center of gravity.

Check valve manufacturers answer the precautions for the initial installation of the hood:
1. When using the public flue, the hood check valve must be equipped. "Our Ruixin hood has its own" separate cigarette pipe is removed, and we can consider not to.
1. The connection between the kitchen flue opening and the flue must be sealed, otherwise, a good hood check valve cannot completely prevent the smell of other people's cooking. In addition to smelling other people's cooking, the students also like to smell other people's cooking. Check valve manufacturer
1. The opening position of the kitchen flue mouth must be high, and try to block the smoke pipe on the ceiling to save the precious space of the hanging cabinet, especially the hood is farther away from the flue mouth. If the smoke pipes are walking in the hanging cabinets, then a long row of hanging cabinets will not be completed and will be occupied by the smoke pipes.
Everyone's attention may not be high when it comes to the flue mouth in the kitchen. Generally speaking, everyone doesn't pay much attention, because only after living in them, everyone can't experience its hidden dangers. In fact, the flue mouth, although small, is a big problem. If you don't deal with the renovations, you may come back to smells and skewers in the future. If the renovation is done, and then research the problem, it is not easy to solve.
