Floor drains are one of the materials for home waterway decoration. Although small but very important, there are often owners who report that the floor drain in the home is blocked, or that there is no deodorant, etc. This is caused by the lack of a suitable floor drain. Every home bathroom balcony needs floor drain. The water can be drained smoothly and there is no water accumulation. Also plays the role of deodorant. When buying floor drains, size is also a key factor. In the market, floor drains are large and small, and there are many kinds of floor drains. When the family purchases floor drains, how do you correctly choose the size of floor drains ? There are many kinds of floor drains. What are the advantages and disadvantages of each floor drain? These problems are plaguing people. The following is a detailed introduction of the types and advantages and disadvantages of ground drains and how to correctly select the size of floor drains . We hope to help everyone solve the problems.
What is a floor drain?
Floor drain is an important connection between the drainage pipe system and the indoor ground. As an important part of the drainage system in a dwelling, its performance directly affects the quality of indoor air, and it is very important to control the odor in the bathroom.
Floor drain type and advantages and disadvantages analysis:
1. Shallow Water Sealed Floor Drainage: Shallow water seal floor drain has the longest history. Its biggest drawback is that if it is not used for a few days, the trap will make the stench of the sewage pipe and the pest directly drive into the shallow water seal because it does not contain water. It is easy to dry without water, and there is a high drainage pressure on the floor that causes water seal damage.
2, deep water seal leakage: Some manufacturers in order to overcome the above drawbacks, the water seal heightening, about 7-8cm, and test with quartz sand, shows that the water flow is quick, sand can be washed out, will not be blocked, but the actual Situation There is rarely sand in the bathroom. Sewage contains a lot of slime impurities, the deeper the water seal, the larger the area of ​​the hair and these slime impurities that hangs, sticks to the bottom of the trap, and cannot be cleaned. After a certain period of time, the passage of water becomes increasingly narrow. Drainage is not smooth; at the same time, the overall height of the floor drain has increased, resulting in the installation of many places where the pipeline is too shallow to be installed. Therefore, when purchasing a floor drain, we must also be optimistic about whether the length of the drain pipe can be fitted with an extended floor drain.
3, wide-mouth water seal floor drain: wide-mouth water seal floor drain, is an upgraded version of the deep-water seal floor drain This wide-mouth water seal floor drain outlet design a single outlet, you can do fast drainage and not blocking, and the water seal can block 100% deodorant Insect protection. At present, the price of such floor drains is high.
Advantages: Effective deodorization for a long time Disadvantages: less products on the top, expensive
4, deduction of water seal floor drain: the principle of deduction floor drain is the back of the lid and a piece of floor drain to form a water seal deodorant. However, because the water seal is extremely shallow, the effective water seal for a genuine pipe is only about half a centimeter. As long as the upstairs toilet flushes, the positive and negative pressure in the pipeline will destroy the water in the floor drain. The odor goes unobstructed into the room and this floor drain cannot effectively deodorise. And because of its own design flaws, the floor drains are easily clogged and drainage is slow. (Note: The national building drainage specification expressly stipulates that this kind of shallow water seal floor drain must be eliminated from the prohibition project and the use of decoration)
Disadvantages: This kind of defecate water seal leakage, can not effectively deodorant, easy to plug drainage slow. Advantages: The price is cheaper.
5, spring-type floor drain: divided into bomb-style and bomb-style. The type of bomb is to press the cover plate, and the cover plate springs up and press again, it will reset; the next type of spring is used to stretch the sealing gasket at the lower end of the sealing core to seal because the spring is made of boron iron, which is easy to rust and elasticity gradually. Weakened until failure, life is not long, and the spring is easy to wind around the hair, fabric, easy to clean.
Advantages: Deodorant effect is very good. Disadvantages: Drainage speed is slow, and it is easy to block for home use.
6, flip floor drain: is the use of gravity to open the case of water, closed without water. It looks like it will deodorise, but it will actually be used differently.
Disadvantages: These self-sealing floor drains do not deodorise, are easy to plug, and have a short life. Advantages: There are more options for panel styles.
7. Float-type floor drain: Use water buoyancy to float the ball to close the drain to achieve deodorant function. When the water flows into the floor drain, the buoyancy of the water lowers the float and lifts the sewage. When the water floats without water, it will close the water outlet and reach the sealing function. Need to clean up regularly.
Disadvantages: Drainage function is poor, easy to plug, easy to save the dirt from the floating ball and lose the sealing function. Advantages: long life.
8, plastic basket floor drain: use a plastic basket instead of buckle bowl, this is another form of water seal floor drain, but cleaning more convenient.
9. Eccentric block type floor drain: The bottom of the floor drain is sealed with a plastic pad with a lead sinker on one side. The seal is not tight, and the metal pin is easily rusted, damaged, and has no long service life.
10. Magnet stone sealed floor drain: Use two magnets to suck and seal. Due to the poor quality of surface water, such as brushing and other reasons, some iron impurities will be adsorbed between the two magnets and gradually accumulate, which will cause the two magnets to fail to fully absorb and seal the gasket. Completely sealed; In addition, the magnetic force of the magnet in the sewage is not as stable as in the air. The effect of a large magnetic field on the earth also weakens the magnetic force, so the performance is not very stable.
11, mechanical gravity seal floor drain: The principle of mechanical gravity, piston-type structure, the use of sealed core inside the slider and the balance of water flow to open and close the seal. Because it does not require water seals, nor does it rely on external force to seal, so it has stable performance and long life.
How to choose the right drain?
Experts said that the purchase of floor drains requires inspection of indicators for deodorization, drainage, filtration, use time, and location.
First, under any circumstances, the floor drain can completely deodorise. The deodorization function of the floor drain mainly depends on the sealing, and the consumer can select the floor drain of different sealing methods according to the location of the floor drain and the like.
Second, the displacement of the floor drain must meet the requirements for use, and it should be large enough to allow the water to drain quickly even if there is no one at home and the water pipe bursts in the extreme. Displacement can be obtained by requesting a manual or test report. The appropriate displacement should be selected based on the inner diameter of the ground leakage mouth and the different use locations.
Third, the filtration function must be thorough. Insufficient filtration function will cause foreign matter to clog the pipeline. Cleaning will be very troublesome. If the pore size of the filter is not suitable, the time interval for cleaning the foreign material is too short, which also increases the consumer's burden. Experts suggest that the best filter mesh size is between 5mm and 8mm. This will not only prevent foreign objects from falling into the pipe, but also remove foreign materials for 3 to 5 months.
Fourth, the use of time should be long enough, do not always switch. Some mechanical floor drains use plastic as the core. The characteristics of plastics is that they will be brittle after three to five years of use. This type of floor drain core requires high-frequency activity, so that the function of floor drain is not stable enough, and various problems may arise. It needs to be replaced. .
Fifth, the purchase of floor drains also needs to be determined according to the location of use. For example, the amount of flushing in the shower is the largest. In order to ensure that the water can be quickly drained without standing water, the floor drain volume needs to be very large. In addition, the instantaneous amount of water flowing through the washing machine is extremely high, and instantaneous pressure on the water pipe Very big. Experts suggest that if the conditions permit, the best solution is not to use floor drains, but to use dedicated pipe drainage, if only to choose the floor drain, then the best buffer installed at the outlet, so that the instantaneous water pressure becomes smaller, and to use Floor drain for washing machine.
Select the size of the floor drain points:
1, It should be understood when choosing the water seal depth of the product to reach 50mm. Sidewall floor drains, floor drains, and enclosed floor drains are generally not water seals; spill-proof floor drains and multi-channel floor drains are mostly water seals, which should be clearly understood when selected.
2, For the floor drain without water seal, the depth of discharge pipe shall be no less than 50mm in water trap. This part can be configured by a floor drain manufacturer or by a construction unit that has installed a floor drain.
3, The level of the floor drain can be adjusted, and the height of the floor can be adjusted to not less than 35mm to ensure that the height of the floor drain after the floor finish is level with the ground. The water-proof wing ring is installed on the floor to ensure that the floor drain is installed in the floor when it is waterproof.
4, The structure of the floor drain with water seal should be reasonable and smooth, and the debris in the drainage should not be easily precipitated; the cross-section area of ​​each part should be larger than the cross-sectional area of ​​the discharge pipe, and the minimum width of the cross section of the flow channel should not be less than 10mm.
5, In the wet area, such as the shower area, in order to ensure the smoothness of the water, not only can it not be hidden, but also it must be about 10 mm below the ground.
