The floor drain is a device for water drainage in our home. Although the floor drain is small in size, it plays a huge role in life. If the floor drain is well designed, it may cause the floor drain to stink and affect the indoor environment.
So what kind of floor drain deodorization effect is good? Let’s compare the working principles of four common floor drains on the market.
1. Water-sealed floor drain
The design of water-sealed floor drain is bell jar type structure, which is a kind of non-direct sealed floor drain. A water-sealed floor drain is a “U-shaped” water trap that is connected to the mouth of the sewer pipe by a bell jar. The smell of the sewer is sealed by the water in the trap, so it is called “water seal”.
Water-sealed floor drain is a relatively old-fashioned floor drain, so there are many defects in the design: for example, the height of many water seals only reaches 10-20mm, once dry, the stink of the sewer pipe will spill into the room; Even if it can be deepened, it can only delay the return of odor time.
Moreover, the deeper the water seal is not the better, one is because the installation height is limited, the other is because the water seal deepening the natural inner wall attachment will increase, over a long time, there are a lot of dirty sewage will become smelly.
2. Flip core floor drain
The advantage of the flip core floor drain is drainage rather than deodorization. This kind of floor drain is fast, but the dowel is easy to break, the sealing effect is not good, and the natural deodorization effect is relatively poor.
3. Silicone sealed floor drain
Silica gel floor drain is a kind of waterless floor drain. Its material is the silica gel material commonly used for pacifiers. Although the sealing effect is good, it is not corrosion-resistant or insect-resistant, so the service life is usually short. If it is used for washing machine drainage, it is not recommended to choose this material, because the water washing clothes is corrosive sewage.
4. Straight-through sealed floor drain
The straight-through sealed floor drain is a kind of floor drain on the market now, which has three working modes: spring, magnet and reverse gravity.
1. The first is a spring built into the floor drain core. Under normal circumstances, the sealing pad at the bottom of the floor drain core can absorb and seal.
This way of floor drain deodorant effect is good, but the service life will not be too long. Because the spring itself is iron, long time contact with dirty water, easy to rust, oxidation will produce harmful bacteria, is not a healthy choice.
2. The second one is to return the gasket to its position with the suction of the magnet after draining the water to realize automatic sealing.
However, impurities of metal particles are easy to be absorbed on the magnet, and in the long run, the magnetism will decrease, so that it is difficult to return to the sealing pad. The performance of this floor drain is not stable, but the core can be replaced without replacing the entire floor drain.
3. There is another kind of reverse gravity straight closed floor drain, which uses the gravity action of the water flow itself to open the sealing cover plate. It will not be afraid of the corrosion of dirty water and affect the life like a magnet or a spring. At the bottom of the sealing point is the sealing ring design, can better eliminate odor and pests.
Read the above floor drain introduction, about which kind of floor drain deodorization effect is good you still understand? In summary, it seems that the straight through floor drain has a better odor-proof effect. If you are considering replacing the floor drain, I hope the above information will be helpful to you.
