1, deep-water sealed floor drain
The design of water-sealed floor drain is a kind of indirect floor drain. The water-sealed floor drain is called water seal because it is buckled on the sewer mouth with a bell jar to get a U-shaped water storage bend, and the smell of the sewer is sealed by the water in the water storage bend.
Water-sealed floor drain is an old-fashioned floor drain, so there are many defects in its design. For example, the water seal height of many water seals now only reaches10-20 mm. Once it dries up, the odor of sewer pipes will overflow indoors. Even if it can be deepened, it can only delay the backflow of odor. The deeper the water seal, the better. First, the installation height is limited, and second, because the water seal deepens, there will be more attachments on the inner wall, and there will be a lot of dirty sewage after a long time.
2, silica gel core floor drain
Silica gel floor drain is a kind of waterless sealed floor drain, and its material is silica gel material commonly used as nipple. Although the sealing effect is good, it is not resistant to corrosion, insects and rats, so the service life is usually short. If it is a floor drain for washing machine, it is not recommended to choose this material, because the water for washing clothes is highly corrosive sewage.
3. Spring floor drain
Under normal circumstances, the gasket at the bottom of the floor drain core can absorb the seal, and the gasket can be restored to its original position with the help of spring force after drainage. This kind of floor drain has a good deodorizing effect, but its service life will not be too long, because the spring itself is iron, and it is easy to rust when exposed to dirty water for a long time, and it will produce harmful bacteria after oxidation, which is not a healthy choice.
4, submarine gravity seal floor drain
When water flows into the floor drain, the weight of water will open the ABS sealing cover at the bottom, and the water will be discharged quickly and smoothly. After the water flow is interrupted, the ABS sealing cover automatically closes due to gravity, and the gas pests and gas pests in the pipeline and the water flow cannot enter upward because of thorough sealing. The deodorizing effect is obvious.
5. Submarine magnetic seal floor drain
The core of submarine deodorizing floor drain has changed from "core". The material is ABS engineering plastic, and the combination of patented permanent magnet steel magnetic force and specially designed self-gravity active seal can effectively isolate the odor and bacteria in the floor drain indoors.
The difference between ABS engineering plastic floor drain core and metal floor drain core;
Metal floor drain core: metal materials are easily corroded by acid-base gas in sewers, resulting in its loss of deodorization function. Metal materials will produce harmful bacteria after oxidation.
ABS engineering plastics: Strong corrosion resistance, good durability, strong initial synthesis stability, and engineering plastics are healthy and environmentally friendly materials.
