What are the types of floor drains
1. Shallow water seal floor drain
The principle of shallow water sealing floor drain is the function of floor drain and deodorization formed by U-shaped double holes and water storage bends. Among them, the main function of deodorization and leakage prevention still depends on the existence of the medium. When the water flows into the floor drain, due to the special structure of the water trap, the floor drain will always store a part of the water to achieve the purpose of isolating the floor drain from the sewer pipe.
2. Spring type
可分为上射式和下射式。结果式是按下盖板，盖板弹起，再按下则复位；下弹式是用弹簧拉伸密封芯下端的垫片进行密封。由于弹簧是铁硼制成的，容易生锈，弹性逐渐减弱直至失效，寿命不长，而且弹簧容易缠绕头发、织物，不易清洗。
3, wide mouth water seal floor drain
The wide mouth water seal floor drain is an upgraded version of the deep water seal floor drain. The wide mouth water seal floor drain is designed with a single drain port, which can drain fast and not clog, and the water seal can be 100% blocked against odor and insects.
4, buckle cup water seal floor drain
The principle of the buckle cup floor drain is that the back of the cover protrudes a piece and the floor drain body forms a water seal to prevent odor. However, because the water seal is particularly shallow, the effective water seal that really works is only about half a centimeter. This type of floor drain is not effective in preventing odor, and because of its design defects, it is easy to block and drain slowly.
Second, the shortcomings of water-sealed floor drain
1, slow drainage
Slow drainage speed is a major drawback of water-sealed floor drain, especially deep water floor drain, drainage speed will be affected by certain, the drainage of this kind of structure of the floor drain, must be through the upper and lower 180° turn of the narrow circular gap to discharge, easy to show the phenomenon of drainage is not smooth, when the displacement is large, may temporarily present water phenomenon.
2. Clean up the inconvenience
Self-cleaning ability is poor, easy to hang hair, sludge; Use a long time, will backlog a lot of impurities and dirt. Because the water-sealed floor leakage through the water section is small, a large number of solid impurities and viscous materials in the sewage, such as sludge, hair, cloth, etc., in the “U” type water trap is easy to hang, precipitate, the water can not be washed away, and the liquidation is unfavorable, which is easy to cause congestion.
After the above introduction, everyone has an understanding of the types of floor drains, right? There are still many shortcomings of water-sealed floor drain, we should choose according to their actual situation when buying.
