Hardware common sense: what are the floor drains?

The floor drain is an important interface connecting the drainage pipe system and the indoor floor. As an important part of the drainage system in the house, its performance directly affects the quality of the indoor air, and it is very important for the odor control in the bathroom. The floor drain is a must for home decoration Where are the few places, what are the floor drains? The following editor will introduce them one by one.

Hardware common sense: what are the floor drains?

What are the floor drains? According to the deodorant method, the floor drains are mainly divided into three types: water deodorant floor drains, sealed deodorant floor drains and three-proof floor drains.

The anti-odor floor drain is our most traditional and common. It mainly uses the tightness of water to prevent the emission of peculiar smell. In the structure of the floor drain, the water storage bay is the key. Such a floor drain should try to choose a deep water storage bay. You can't just look at the beautiful appearance. According to the relevant standards, the body of the new floor drain should ensure that the water seal height is 5cm, and have a certain ability to keep the water seal from drying up to prevent odor.

Now there are some ultra-thin floor drains on the market, which are very beautiful, but the anti-odor effect is not very obvious. If your bathroom space is not a bright room, then it is best to choose some traditional ones. Sealed anti-odor floor drains refer to adding a The upper cover seals the floor drain body to prevent odor. The advantage of this floor drain is that it looks modern and avant-garde, but the disadvantage is that you have to bend down to lift the cover every time when you use it, which is troublesome.

But recently, an improved sealed floor drain has appeared on the market. There is a spring under the upper cover. When using the upper cover with your foot, the upper cover will pop up, and you can step back when not in use. It is relatively more convenient. Three defenses The floor drain is the most advanced anti-odor floor drain so far. It installs a small floating ball at the lower end of the floor drain body, and uses the water pressure and air pressure in the sewer pipe to withstand the ball so that it is completely closed with the floor drain, thereby Play the role of deodorization, insect repellent and anti-overflow.
