Floor drain classification

  1. Traditional water-sealed floor drain
    This kind of floor drain problem:
    Advantages: cheap, widely used in the products brought by the builders of the rough house.
    Disadvantages: poor self-cleaning ability, easy to block, difficult to clean; slow drainage
  2. Eccentric block type lower flap floor drain
    Use a sealing gasket, fix it with a pin on one side, add a lead block, and use the principle of gravity eccentricity to seal. This structure was initially horizontal, and later evolved into a vertical one with a water seal. When draining, the gasket is opened under the action of water pressure, and after the drainage is finished, the gasket is closed under the gravity of the lead block.
    This kind of floor drain problem:
    Advantages: cheap and easy to produce.
    Disadvantages: (1) The gasket is a mechanical structure and is not tightly sealed; (2) The pin is easily damaged; (3) The flap is easily stuck and does not reset. Basically can not solve the problem of reverberation.
  3. Spring drain
    Use a spring to stretch the gasket at the lower end of the sealing core to seal. When there is no or little water in the floor drain, the gasket is stretched upward by the spring to close the pipe. The water in the floor drain reaches a certain height. When the gravity of the water exceeds the elastic force of the spring, the spring is pressed downward by the water and the gasket opens to automatically drain.
    This kind of floor drain problem:
    Advantages: The deodorant effect is not bad before the spring fails
    Disadvantages: (1) The spring is made of boron iron, and it is easy to rust after long-term contact with sewage, resulting in weakened elasticity, failure, and short life; (2) The spring is easy to wrap around the hair and affect the gasket rebound; (3) The gasket is mechanical The structure is not tightly closed. It needs to be cleaned or replaced frequently, otherwise the deodorizing effect will not be achieved at all.
  4. Iron-absorbing stone floor drain
    The structure of this floor drain is similar to a spring type, and the sealing gasket is sealed by the magnetic force of two magnets. When the water pressure is greater than the magnetic force, the sealing gasket opens downward to drain, and the drainage ends, and the water pressure decreases. When the water pressure is less than the magnetic force, the magnet block attracts and the sealing gasket pulls up.
    This kind of floor drain problem:
    Advantages: different types of plastic cores can be processed.
    Disadvantages: (1) Due to the poor water quality of the ground sewage, such as washing items, brushing the floor and other reasons, some iron impurities will be adsorbed on the iron absorption stone. After a period of time, the impurity layer will cause the gasket to fail to close and fail to lift. To deodorize; (2) The magnetic force will gradually weaken and disappear, which will affect the opening and closing of the gasket up and down, and it is easy to malfunction.
  5. Gravity floor drain
    No water seal is required, springs, magnets and other external forces are not used, and the balance between the gravity of the water flow and the floating ball inside the floor drain is used to automatically open and close the sealing cover. This mode is similar to the spring type, except that the elastic force is converted into buoyancy to drive mechanical pulling force.
    This kind of floor drain problem:
    Advantages: The integrated filter is not easy to lose.
    Disadvantages: (1) There are spiral mechanical parts inside the floor drain core. Long-term work in sewage will rust or deposit silt, which will prevent the buoyancy ball from moving up and down, affecting drainage, odor resistance and bacteria prevention; (2) The sealing cover will also be deposited due to siltation Hair, silt, and sand cause loose sealing, which affects deodorization and anti-bacteria.
  6. Silicone floor drain
    Use two thin pieces of silicone or a silicone bag with an opening at the bottom to seal it. When draining, the bottom of the silica gel is washed away by water. After the drain is completed, the bottom of the silica gel automatically fits due to its own elastic force and the opening due to residual moisture to achieve the deodorant effect.
    This kind of floor drain problem:
    Advantages: silica gel has good anti-aging properties and self-elasticity, good deodorization performance, and fast drainage.
    Disadvantages: mechanical opening and closing is not durable under normal circumstances.
  7. New water-sealed floor drain
    The water-sealed floor drain is a floor drain with a long-lasting deodorant effect on the market!
    The water-sealed floor drain uses the bell or casing device in the water storage cavity to form an “N” or “U”-shaped water storage bend. The water seal is used to isolate the odor and germs in the drainage pipe and achieve the deodorizing effect. Floor drain.
    This kind of floor drain problem:
    Advantages: long-term use will not break without mechanical principles, and the effect is good.
    Disadvantages: The cost of stainless steel cores is higher.
