Flue check valve to participate in the smoke management, to a large extent, solve the problem of exhaust. On the market in general because only non-return valve is not in place, not a ginseng smoke management. All the variable pressure valve can pull.

2, equipped with a block in the body into FengKouChu oil net, net one oil box, oil baffle network connected to the body to activity inlets, smoke form; After oil baffle net check valve cavity body is equipped with a whole plate damper; The air inlet pipe body suit in check valve cavity body; Damper by fixed to the inlet pipe wall on the eccentric shaft is installed on the pipe body, around the shaft opening and closing the outlet check valve.
The installation of flue check valve to note:
Be sure to keep 1, deputy flue
Each kitchen has the flue, flue is divided into main at the same time, throughout the building, the main flue and flue is relatively independent. General lampblack is first to the deputy flue in the home, and then through the diaphragm plates into the main flue, which can ensure household lampblack is isolated. And if the vice flue connected directly to the main flue, will be due to low pressure DaoYan or smoke.
2, the construction should pay attention to details
First, select the smoke lampblack machine installation location is important. Pipes as short as possible. Some owners have to beautiful, pull the pipe is longer, as a result, after turn off lampblack machine, pipe will gather many lampblack not to go out, then fell back to the room. In addition, in order not to damage the original main flue, and the opening direction can not optional change, be sure to play inside the vice flue.
3, Windows, exhaust pay attention to safety
Some owners in order to avoid the problem of smoke, give up the original flue, directly on the window opening smoke, it can be to do so, but there are a few points to note.
First before the window or wall to open hole must be with the approval of the property; Secondly, pay attention to safety problems, generally is the metal material at the end of the exhaust pipe, if the open hole is too small, metal heat transfer may make glass crack, and pedestrians, and pipe lead to out of the window, the strong north wind to blow will cause lampblack flow backward. Best will go down the pipe after pipe out, this can also avoid the rain rain water into the pipe, and the windshield on the outside.
4, non-return valve frequently replaced
If have deputy flue to dismantle, or need to prevent DaoYan effect is better, then use the flue check valve. In general, the check valve of lampblack machine effect is not obvious, and in flue check valve may be applying a cigarette machine installation, make the flue smoke not to flow backward into the pipe and smoke lampblack machine. However, after install the check valve to regular cleaning, otherwise it will make the check valve is open, lose their effect, and the best flue check valve replaced every two years or so.
