What is the principle of floor drain deodorization?
Different types of deodorizing floor drains have different deodorizing principles:
1, water-sealed floor drain: deodorize by the water in the trap. Disadvantages: the floor drain must have water, otherwise it can't deodorize.
2. Eccentric block type: that is, a gasket is fixed with a pin and sealed by the principle of gravity eccentricity. One is that the seal is not tight, and the other is that the pin is easy to be damaged, which leads to failure.
3. Spring type: it can be divided into upper type and lower type. The upper spring type is to press the cover plate, which will spring up and reset after being pressed again; The bottom spring type is sealed by stretching the gasket at the lower end of the sealing core with a spring. Because the spring is made of boron and iron, it is easy to rust, and its elasticity gradually weakens until it fails, and its life is not long. In addition, the spring is easy to entangle hair and fabric, and it is not easy to clean.
4. Magnet type: two magnets are used to magnetically attract the gasket for sealing. Due to the poor quality of surface water such as washing articles and brushing floors, some iron impurities will be adsorbed on the magnets. After a period of time, the impurity layer will cause the gasket to fail to close. In addition, due to the role of the earth's magnetic field, the magnetic force will gradually weaken.
5. Mechanical type: there is no water seal, no external force such as spring and magnet, and the gasket is reversely opened and closed by gravity principle. There are no obvious defects.
Matters needing attention in purchasing odor-proof floor drain
The first is the size of the odor-resistant floor drain. When the real estate developer delivers, the reserved drainage hole is relatively large and needs to be repaired by the decoration personnel. Many owners choose the floor drain in the later stage of decoration according to the size of the floor drain that has been trimmed by the decoration team, but the floor drain on the market is the overall standard size, so it happens from time to time that they can't choose satisfactory products. Therefore, it is suggested that the owner choose his favorite floor drain in the decoration design stage, and then construct it according to the size of the floor drain. In addition, the aperture of local air leakage grate should be controlled between 6 and 8 mm to prevent dirt such as hair, sludge and sand from leaking into the sky.
The second point to grasp is that there should not be too many entrances for multi-channel floor drains. Multi-channel floor drain is a product developed in recent years. A main body usually has 3 to 4 water inlets (for washing face, bathtub, washing machine and exhaust). This structure not only affects the drainage of the floor drain, but also does not conform to the actual design situation. Therefore, there should not be too many water inlets for multi-channel floor drains, and only two (air and bathtub or air and washing machine) can meet the needs.
