Why not use bell-type floor drain?

Floor drain is an inconspicuous sanitary equipment for removing indoor groundwater. Because of its small size and low price, it has been neglected in family decoration. In fact, although the floor drain is small, it has a great impact on home health.

I wonder if you have noticed:

When it's raining or windy, the bathroom will give off the smell of sewer and go straight into the room.

When I get up in the morning, the bathroom smells of damp sewers.

Just a few days after I came back from a business trip, the whole room smelled of sewers.

The house has just been exterminated by cockroaches, and within two days, it is full of cockroaches.

In cold winter or hot summer, doors and windows are closed. When we turn on the range hood to cook, there will be bursts of odor coming out of the floor drain.

Similarly, in order to eliminate the odor in the room, many friends will always leave the exhaust fan in the bathroom on. You don't know that the more this happens, the bigger the smell in the room.

In fact, these are all caused by floor drains! According to the survey, 80% of the rooms have the above problems, but sometimes we don't pay attention to them and don't know why.

Why are there these problems?

For a long time, people's understanding of floor drain has been greatly deviated. They all think it's just a small accessory, installed in the corner, insignificant. However, although the floor drain is small, it is related to the health and quality of life of thousands of families. Under the building where we live, there are criss-crossing drainage pipes and septic tanks, which contain a lot of harmful gases such as CO, CO2, fecal odor and hydrogen sulfide. The floor drain is the only channel connecting the drain pipe with the room. According to WHO's investigation, the reason why SARS spreads widely in many places is that sewers are connected in series, floor drains are not completely sealed, and bacteria spread indoors through drainage pipes.

Most families have encountered the odor of floor drain, as well as serious problems such as sewage overflow and insects crawling out. Why are there these problems? This is because the floor drain is the connection between the sewer and septic tank and the living room space. The old floor drain relies on the water stored in the floor drain itself to form a water seal, which separates the living room space from the piping system. However, the "water seal" of the old floor drain is easily destroyed. Once destroyed, sewers and even septic tanks are connected to indoor space without any barrier. Toxic and harmful gases such as fecal odor, carbon monoxide, carbon dioxide, methane and hydrogen sulfide in sewers will do harm to human health.

However, people who have experienced the baptism of SARS, with the improvement of housing hygiene requirements, the once neglected "dead corner" of sewer system has been paid more and more attention.

Not long ago, some experts in the industry listed the common phenomenon of "smelly floor drain" in residential buildings as one of the six problems that need to be solved urgently to improve the sanitary standard of residential buildings, in view of the blockage of traps, the failure of odor-resistant water seals and the opening of floor drains in China's current residential sewer system.

Consumers also clearly issued a warning to the director-healthy rooms can not leave "dead ends." When buying a house, you should not only look at the environmental performance of paint, floor, doors and windows, but also ask what brand the floor drain is, whether it can prevent odor and has four prevention functions. If the floor drain is not properly closed, it will smell bad every day in the future.

Therefore, from the point of view of healthy residence, it is necessary to have a new and operable sealed floor drain to fundamentally solve the problems such as "odor return" of the floor drain.

The market status and analysis results of floor drain are as follows:

1. Status: The odor problem of sewer pipes is very common and serious, and it has not been well solved since the founding of the People's Republic of China for more than 50 years. With the progress of society and the improvement of people's quality of life and health, especially the spread of SARS, people have attached great importance to this issue. The decoration market has listed sewer pollution, formaldehyde and benzene pollution as two major indoor pollution. Floor drain is no longer a simple ground drainer, but also an essential indoor sealing device.

(1)98% of users use water-sealed floor drains, and the water seal height is not enough. The height of the national standard water seal is 5cm, and most of them are only 1-2 cm, which can't deodorize at all.

(2) The materials are mixed: stainless iron, zinc alloy, copper and other materials are used as inferior materials.

2. Conclusion:

(1) capacity: With the current development speed of real estate in China, as a building necessity, the annual consumption of floor drains is above 1 100 million. With the renovation of old buildings, the market capacity is immeasurable;

(2) The industry is mixed, the brand has not yet been formed, and the competition is not as fierce as that in the industries such as floor, tile, paint and sanitary ware, which has not attracted enough attention. This is a huge blank market.

The submarine T-type automatic sealing four-proof floor drain completely revolutionized the function of floor drain;

1, effective sealing, excellent four-prevention function, effective deodorization, overflow prevention, antibacterial and blockage prevention.

2, independent drainage, large displacement;

3. Unique self-cleaning function to prevent fibers and hairs in sewage from blocking the sewer;

4, can be directly used as cleaning mouth, more convenient installation!

Comparative analysis of various floor drains

What are the problems of floor drain in building materials market at present?

1, spring self-sealing floor drain

Advantages: fast drainage.

Disadvantages: the spring is very easy to fail; The cover plate is easy to be dirty, and the sealing performance cannot be guaranteed after being dirty.

2, seesaw self-sealing floor drain

Advantages: fast drainage.

Disadvantages: bearings are easy to fail; The cover plate is easy to be dirty, and the sealing performance cannot be guaranteed after being dirty.

Disadvantages: the ground needs to be raised.

3. Traditional water-sealed floor drain

Advantages: cheap; Thin; The deodorizing effect is good when the water seal does not fail.

Disadvantages: shallow water seal; It is easy to dry up and fail if it is not used for a long time; Cockroaches are easy to get in, and it is difficult to clean up the dirty things inside.

① The water seal height is small. (2) The hydraulic conditions are poor, and impurities are easy to deposit at the bottom, blocking the waterway. (3) bell jar (buckle bowl) easy to dismantle, damage the water seal.

We believe that these shortcomings should be analyzed in detail.

(1) The height of water seal is small. This is not the disadvantage brought by the bell-type floor drain structure, and the bell-type floor drain can reach enough water seal height. Bell-type floor drain with insufficient water seal height belongs to unqualified products that do not meet the requirements of design specifications; In the future, there will be a national standard or line standard for floor drain products, which are also products that do not meet the requirements of the national standard or line standard. We can't deny the bell-type floor drain just because the water seal height is not enough, because this is not the shortcoming of the bell-type floor drain itself, just like the water seal height of the trap in the national standard of Gray Cast Iron Pipe Fittings for Drainage (GB87 16-88) is less than 50 mm, so we can't deny the trap.

(2) Poor hydraulic conditions. For all water sealing devices, the water flow is downward first, then upward, and flows through two sharp turns of 180. Bell type floor drain is no exception. The water seal structure of bell-type floor drain has a similar form in the trap form of washbasin or bathtub. The reasons why bell-type floor drain is easier to deposit impurities at the bottom than washbasin or bathtub with the same trap form are as follows: ① Besides the narrow annular gap, the main reasons are as follows: ① The standard height of floor drain is set to exclude surface water, and the water quality is poor and there are many impurities. ② Low water head makes it difficult to meet the requirements of self-cleaning flow rate.

(3) It is a fact that the bell jar was dismantled. Because the water channel is blocked, in order to facilitate drainage, it is sometimes solved by removing the bell jar (buckle bowl). It is a disadvantage that the bell jar (or buckle bowl) can be easily removed, but it is also an advantage. Because of this, the bell-type floor drain can easily remove dirt. At the same time, when the drain pipe is blocked, people can dredge the drain pipe by removing the bell-shaped floor drain behind the clock, which is much easier than opening the cleaning mouth of the horizontal pipe. On the other hand, the trap of sanitary ware will also be blocked, which is often removed by removing the plug and cover plate in the lower half of the trap or the lower part of the trap. It will be reset immediately after cleaning, and the drainage and water sealing functions will be restored. Removing the bell jar does not affect the drainage function of the floor drain, but only affects the function of the water seal to prevent harmful gas from flowing back, which is often ignored because the user does not understand or agree.

First, drainage capacity is the minimum requirement of floor drain, because it is originally used to remove ground wastewater. The necessity of floor drain installation is also reflected in that it is used as an emergency leak after a burst pipe or faucet fails to close, so as to avoid the expansion of flood loss after a burst pipe or faucet fails to close.

Second, the depth of the water seal, you may not understand this, first of all, we need to know what the water seal is? Water seal is a water storage device in the floor drain to prevent odor from escaping. What is the depth of water seal? Refers to the vertical distance between the highest water surface of the trap and the lower mouth of the water seal in the floor drain. Regarding this vertical distance or water seal depth, the national water supply and drainage compulsory regulations: the water seal depth of the trap floor drain should not be less than 50 mm

Third, the ability to clean sewage is a problem that everyone deeply understands, which can also be seen from the continuous prosperity of sewage business. Once a long-term deposition trap is blocked, you usually have to pay for it.

The above three requirements restrict each other. Why? First look at the depth of the water seal. From the perspective of deodorization, the deeper the water seal, the better. For example, the depth of the water seal is too small, which will make you dizzy. At that moment, it may bring you fatal injury. The SARS virus in Amoy Garden in Hong Kong is a warning. However, the water seal should not be too deep, because the flow pattern of surface drainage is gravity flow, and the relative effect of surface drainage is low water head and small instantaneous flow. Excluding those products whose water seal depth is less than 5 cm, there is no room for discussion >, we have used water seal floor drain products for decades, which have large resistance, small flow rate and low self-cleaning ability, and fine dirt is easy to hang up, grow biofilm and block the channel; Therefore, the disadvantage of bell-type floor drain is that it is easy to block and the water seal cannot be too deep. The deeper the water seal, the more blocked it is. People don't like to use it because it is easy to jam and people often have to clean up the sundries inside. Because it was easy to cover, people took the cover away. Because there is no cover, the water seal does not exist, causing the smell to escape. The floor drain has only one basic function, that is, drainage. Although the drainage capacity is the best at this time, the sewer.

It can be seen that the three basic conditions of floor drain are: first, the drainage capacity without water seal device is the best condition; Secondly, the deeper the water seal, the best deodorization effect; Third, the best condition is that there is no water seal device. Then, in order to meet the drainage capacity and sewage discharge capacity, can we reduce the water seal depth or cancel the water seal device? The answer is definitely no. Isn't this a contradiction? Answer; However, this problem is also a difficult problem that has plagued the water supply and drainage industry for many years. So how to deal with this problem? , or how to seek an ideal harmony and balance in these three requirements?

T-type automatic sealing and four-prevention environmental floor drain of submarine submarine is the best choice for the coordination and balance of these three basic requirements! Really deodorize, waterproof, antibacterial and anti-clogging, and at the same time, it has a superior cost performance, so that you can do it once and for all!

It is a floor drain device which uses the principle of permanent magnet weight balance to brake up and down. Through accurate calculation of gravity and magnetic force and ingenious design of structure, the gasket can be opened freely and automatic sealing can be realized. When the floor drain works, when the water flows into the floor drain to a certain amount, the ABS gasket at the bottom will be opened by the gravity of the water, and the water will be unblocked. After the water flow is interrupted, the ABS gasket automatically closes due to magnetic force, completely sealing the gas, pests and spills in the pipeline. Because of its unique wide-mouth downspout, the drainage is rapid. Accurate calculation, ingenious structural design, the largest stroke when the gasket is opened when draining, and the displacement is huge, which will never be blocked. With its special T-shaped structure, there is no place where hair and dirt are easy to hang, and the phenomenon of hanging objects blocking will not be formed, so that everything that can enter can come out, which completely solves the problem that other floor drains are easy to block. The main body of this product is made of ABS material, which can resist strong acid and alkali and liquid with high temperature of 80 degrees Celsius, and its life is semi-permanent. This product has applied for four national patents. If SARS led to the revolution of floor drain, then the submarine T-type automatic sealing four-prevention floor drain is undoubtedly the leader of this revolution.
