Which is better, water seal or self-sealing floor drain? What kinds of floor drains are there?

Floor drains are still widely used in our home life, especially in bathroom decoration. There are many kinds of floor drains on the market now, and different kinds of floor drains have different functions. Water seal and self-sealing floor drain are common in the market, and they are also two kinds of floor drains that people like to compare. Next, let's see which is better, water seal or self-sealing floor drain. What kinds of floor drains are there?

Which is better, water seal or self-sealing floor drain?

First, the water seal floor drain?

1. Advantages

Water-sealed floor drain is more flexible than traditional sewer, which can effectively prevent all kinds of mosquitoes from entering the room under the condition of ensuring water flow. Moreover, with the continuous improvement of water-sealed floor drain, a new generation of water-sealed floor drain can largely prevent odor and improve indoor hygiene.

2. Deficiencies

Because the function of water-sealed floor drain is to let water flow through, enter the sewer and then discharge. Therefore, its drain is very small and it is easy to be blocked by other sundries. In daily management, it needs regular maintenance and cleaning. Otherwise, long-term neglect will cause serious problems.

Second, the self-sealing floor drain is made of advanced technology and technical equipment. Self-sealing floor drain has its own unique function:

1. Drawing process is adopted.

2. Use rubber sealing ring to prevent odor rebound.

3. Displacement is controlled by water pressure, which flushes the sealing ring, stretching the spring and discharging the sewage.

4. Use the spring to stretch the sealing port to control the drainage flow.

4, self-sealing floor drain national standard:

4.5. The selection of10 self-sealing floor drain shall meet the following requirements.

(1) deodorant floor drain is preferred.

(2) Drainage devices should be set up in places with high sanitary standards or places where floor drains are not often used.

5, the main function of the bouncing floor drain:

(1) Drainage

(2) sealing

(3) Deodorization

(4) self-styled

What kinds of floor drains are there?

1. Shallow water sealing floor drain: Shallow water sealing floor drain has a long history. One of its major defects is that if it is not used for a few days, the odor and pests in the sewer pipe will drive directly to the shallow water seal because there is no water in the trap. It needs to be used frequently, otherwise the water will dry up easily, and the water seal will be destroyed due to the high drainage pressure of the building. Shallow water sealed floor drain has been gradually covered.

2. Deep-water floor drain: In order to overcome the above shortcomings, some manufacturers raised the water seal to about 7-8 cm and used quartz sand for experiments. The surface water flows quickly, and sand can be washed out without clogging, but in fact there is little sand in the bathroom. Sewage contains a lot of viscous impurities. The deeper the water seal, the larger the attachment area of hair and these sticky impurities will be, and they will stick to the bottom of the trap and cannot be cleaned. After a period of time, the waterway will become narrower and narrower and the drainage will not be smooth. At the same time, the overall height of the floor drain increases, resulting in many pipes can not be installed in shallow places. Therefore, when buying a floor drain, we should also be optimistic about whether the height of the drain pipe can be installed with an extended floor drain.

Third, the wide-mouth sealed floor drain: the wide-mouth sealed floor drain is an upgraded version of the deep-water sealed floor drain. This wide-mouth sealed floor drain adopts single drainage design, which can drain quickly without blocking, and the water seal can block off odor and insects. At present, this kind of floor drain is relatively expensive.

Advantages: It can effectively deodorize for a long time. Disadvantages: the above products are few and expensive.

Fourth, buckle the cup to seal the floor drain: the principle of buckle the cup floor drain is that a piece protruding from the back of the cover forms a water seal with the inside of the floor drain to prevent odor. But because the water seal is very shallow, the effective water seal that really works is only about half a centimeter. As long as the upstairs toilet is flushed, the positive and negative pressure in the pipeline will destroy the water in the floor drain. Odor will enter the room unimpeded, and this floor drain can't effectively prevent odor. Moreover, the floor drain is easy to block and drain slowly because of its own design defects. (Note: The national building drainage code clearly stipulates that this kind of shallow water sealing floor drain must be eliminated, and it is forbidden to be used in engineering and decoration. )

Disadvantages: this kind of water-sealed floor drain can not effectively prevent odor, and it is easy to block and drain slowly. Advantages: the price is cheaper.

5. Spring floor drain: it can be divided into upper spring type and lower spring 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, it is easy to entangle hair and fabric in spring, and it is not easy to clean.

Advantages: Good deodorizing effect. Disadvantages: the drainage speed is slow and the household is easily blocked.
