"Q: Fanxiang, the neighbor next door, will drift to our house once, why does the oil fume drift to our house?"
That is because there is no EPP check valve installed in the home !!!
1. What is a check valve
The little friends who have renovated the interior must not be unfamiliar when they hear this word. The biggest function of the check valve is to avoid the backflow of oil and smoke!
Therefore, how can the lampblack be poured back?
Because the public flue of the residential area is connected.
Like everyone’s residential quarters now, there is a main flue and a secondary flue. The cooking fume from your cooking at home is discharged into the secondary flue according to the flue opening, and then into the main flue, because the temperature of the cooking fume is higher than the outside air. , So it’s very simple to raise the discharge!
When the temperature is very hot, or because of the standard pressure, the oily smoke cannot be discharged immediately, and it is lonely and boring in the flue. It is very likely that you want to drop by...
The flue EPP check valve is a door of the flue, which is opened when the exhaust system is used, and closed when the exhaust system is not.
And when the "door" is not necessarily closed at home, but the "door" is not installed at all, the lampblack thinks, is it coming in? Still come in? So the cooking fume was poured in at home!
If you don't like the aroma of other people's rice, add oil fume check valve.
2. Buy check valve
Choosing to install a check valve, then there is a second problem, how to choose a check valve?
✦ Plastic or stainless steel
"Can stainless steel be inferior to plastic? Choose stainless steel!"
"But most people choose plastic, and everyone must have chosen it right"
Indeed, plastics seem to be inferior to stainless steel in terms of durability and layering. But this is not the case!
The stainless steel check valve does not have a sealant gasket because of the limited processing technology.
It is airtight, and it is not as good as a plastic check valve. The oil fume will flow back after a long time.
The check valve hangs so high, and there is no need to restrict stumbling. The tightness is the last word, so choose a plastic check valve!
✦ Are all plastic check valves the same?
Even all plastic is good or bad. The key materials of plastic check valve are: PE, PC, ABS, PP.
Value for money to inferior: PC> ABS> PP> PE; ABS and PP currently on the market are more usable.
✦ Specification selection
It's not easy to have friends, don't buy blindly according to the specifications? If so, then consider buying a experience!
The general specifications of the flue check valve are 15cm, 16cm, 18cm, immediately take a straightedge and measure your flue opening!
3. Check valve pp material manufacturer
How to choose a reliable plastic manufacturer is also one of the most concerned things.
Here I would like to recommend a supplier of EPP raw material manufacturer——Wuxi Hi-Tec Environmental Material Co., Ltd. (HTEC).
HTEC is a national emerging company specializing in the development, design, manufacturing and molding of advanced foamed polymers.
It is an outstanding leader in the domestic EPP plastic industry.
