The floor drain is an important interface to connect the drainage pipe system and the indoor ground. As an important part of the drainage system in the house, its performance is directly affecting the quality of indoor air, which is very important for the odor control in the bathroom.
What are the classifications of floor drain
1. Traditional water seal floor drain
The problem of this kind of floor drain:
Advantages: cheap, widely used in the built -in building dealers with products.
Disadvantages: poor self -clearing ability, easy to block, not easy to clean; slow drainage speed
2. Eccriped block underwater flip floor drain
Use a sealing pad, fix it with a sale, add a lead block, and use the principle of gravity bias to seal.This structure was originally horizontal, and later evolved the vertical, vertical water seal.When drainage, the gasket is opened under the action of water pressure. After the drainage is over, the gasket is closed under the action of the lead block.
The problem of this kind of floor drain:
Advantages: cheap and easy to produce.
Disadvantages: (1) The pad is a mechanical structure that is not strictly closed; (2) the nails are easy to damage;Basically cannot solve the problem of return.
3. Spring floor drain
Seal with the sealing pad at the lower end of the dense sealing core.When there is no water or water in the floor drain, the sealing pad is stretched up by the spring and closed the pipe. When the water in the local leakage reaches a certain height, the gravity of the water exceeds the spring elastic force, the spring is compressed downward by the water, the sealing pad is opened, and the automatic drainage.
The problem of this kind of floor drain:
Advantages: Before the spring did not fail, the anti -deodorization effect was good
Disadvantages: (1) Spring is made of boron iron. It is easy to rust for long -term contact with sewage, which will cause elasticity to weaken, failure, and not long life; (2) Spring is easy to wrap the hair and affect the pads back; (3) The pads are mechanical machineryStructure, closure is not strict.Need to clean or replace it frequently, otherwise there will be no deodorant effect.
4. Moisture -sucking stone -style floor drain
The structure of this floor drain is similar to a spring type, which is sealed with a magnetic suction of two magnets.When the water pressure is greater than the magnetic force, the sealing pad is turned on down the drain, the drain is over, and the water pressure is reduced. When the magnetic force is smaller than the magnetic force, the magnetic block is sucked and the sealing pad is pulled up.
The problem of this kind of floor drain:
Advantages: Different types of plastic materials can be processed.
Disadvantages: (1) Due to the poor water quality of the ground, such as washing items, brushing ground and other reasons, some iron impurities will be adsorbed on iron suction. After a period of timeTo the effect of deodorization; (2) the magnetic force will gradually weaken and disappear, affecting the upper and lower closure of the sealing pad, which is easy to fail.
5. Gravity floor drain
Do not need water sealing, do not use external forces such as spring, magnets, etc., use the water currents own gravity and the balanced relationship between the floating ball inside the floor drain, and automatically open and close the sealing cover.This pattern is similar to the spring type, just converting elasticity into buoyancy to drive mechanical pulling force.
The problem of this kind of floor drain:
Advantages: Filtering is not easy to lose.
Disadvantages: (1) There is a spiral machine inside the ground leak core. It will work in sewage for a long time to rust or deposit and sediment, which hinders the movement of the buoyancy ball up and down, affecting drainage, deodorant, and anti -bacteria;Hair and sediment cause the sealing is not tight, affecting deodorant and anti -bacterial.
6. Silicone floor drain
Seal with two thin silicone or silicone bags opened at the bottom.The bottom of the silicone was washed away by water during drainage. After the drainage was over, the bottom of the silicone was automatically fitted due to its own elastic effect and opening due to residual moisture to achieve deodorant effect.
The problem of this kind of floor drain:
Advantages: Silicones anti -aging performance and good elasticity, good deodorant performance, and fast drainage.
Disadvantages: Mechanical opening and closing is not durable in the case of silicone.
7. New water -seal floor drain
Water seal floor drain is a long -term floor drain on the market!
Water seal floor drain is a "N" or "U" type of water storage curve using the clock or sleeve device in the water storage cavity.The floor drain.
The problem of this kind of floor drain:
Advantages: Long -term use will not be broken and there is no mechanical principle, and the effect is good.
Disadvantages: Stainless steel core costs are high.
Select the main point of floor drain
1) The standard for CJ/T 186-2003 is only applicable to the floor drain used by general industrial and civil buildings, and it is not suitable for special places such as anti-wave floor drain for private defense engineering, and explosion-proof floor drain for petrochemical enterprises.In addition to referring to this standard, the floor drain of special places should also meet the technical requirements of the relevant industries.
2) Water seal is one of the important features of water seal floor drain.When choosing, you should understand whether the water seal depth of the product is 50mm.Most of the side wall -type floor drains, mesh floor drain, and closed floor drain are generally not water -sealing; most of the anti -spot drain and multi -channel floor drain are mostly water -sealed. When selection, you should understand according to the manufacturers information.
For water -sealing floor drain, the depth of water sealing in the floor drain should not be less than 50mm.This part can be configured by the floor drain manufacturer, or a construction unit of the installation of the floor drain.
3) The height of the floor drain can be adjusted, and the adjustment height is not less than 35mm to ensure that the floor drain high after the ground decoration is completed and the ground is flat.The waterproof wing ring is to do a good job of waterproofing the waterproofing when the floor drain is installed on the floor.
Located in the underground garage car passage or the floor drain in the heavy place, its tweeter strength should meet the corresponding loads.
4) The structure of water -sealing floor leaks should be reasonable and smooth, and the debris in the drainage should not be easily settled; the excessive surface area of ??each part should be greater than the cross -sectional area of ??the drainage pipe, and the minimum net width of the flow channel section should not be less than 10mm.
5) There are three types of floor drain connections: inheritance; thread; stuck.The size of the connection can be determined in accordance with the relevant regulations of the current state
6) Priority should be used to use deodorant floor drain. Where there is no need for drainage, you can set up a floor drain.Builders leaks are not set up without setting up the land.
