The traditional water-sealed floor drain is a bell-shaped structure, that is, a buckle bowl (bell-shaped) is buckled on the sewer crossing to form a U-shaped trap, so as to achieve the purpose of sealing, so it is called "water seal". It has the following problems:
1, odor pollution 2, spread of pests and germs 3, poor self-cleaning ability, easy blockage and difficult cleaning 4, slow drainage speed.
1. At present, most floor drains on the market are mainly made of stainless steel and copper, and there are also zinc alloys (zinc alloys have poor corrosion resistance). Stainless steel is easy to distinguish, but copper-zinc alloy is difficult to distinguish. At present, the general zinc alloy casting, the groove under the mold is the same. Copper products are also cast, but many of them are machined, so it is a way to distinguish zinc alloy from copper. Another point is that zinc alloy is relatively light in weight, but this is not accurate. The price of stainless steel is cheaper than copper, and it is similar from the point of view of use, but copper looks more textured. Also, when choosing a product, we must pay attention to the function of the product: (1) Can it be sealed well? (2) What is drainage flow? (3) Is it inconvenient to clean up?
2. When decorating or transforming the floor drain, be sure to find out the various sizes of the floor drain at home, such as the diameter of the sewer pipe, the height of the sewer pipe from the ground, and the size of the panel. When choosing a floor drain, we must follow these dimensions. Will it be very troublesome? I suggest that you don't be greedy when choosing a floor drain. Generally, the price of stainless steel floor drain is 30-the price of 40 yuan floor drain and copper floor drain is 70-that of 80 yuan.
3. Now introduce the representative floor drain on the market.
(1) coreless four-way floor drain is an upgraded product based on the original four-way floor drain. Its principle is to use its own gravity to open and close the gasket to achieve the sealing effect, and the drainage speed is fast, and the floor drain of the washing machine does not return water at all. The manufacturer's warranty period is 5 years.
(2) Submarine floor drain, which uses the magnetic force of magnet to open and close the gasket. Generally, magnets will demagnetize after being used for a long time, but manufacturers say that the permanent magnet steel used will never demagnetize, and the drainage speed is fast, but it belongs to drainage, and only when the weight of water is greater than the magnetic force will it drain. The manufacturer's warranty period is two years.
(3) Songshan floor drain, using the principle of spring opening and closing gasket, usually the spring floor drain is easy to lose its elasticity after a period of use, or some hair is entangled, and the sealing effect is gone. The manufacturer's warranty period is two years.
(4) Bongo floor drain, with two pieces of silica gel to achieve sealing effect. This floor drain has a simple design. There are two 45-degree silica gel sheets in the sealing core. It is said that the sealing effect in the floor drain is the worst, and the manufacturer's warranty is 2 years.
(5) Six-proof floor drain, which belongs to high water-sealed floor drain, has good deodorization effect and slow drainage speed, which is the biggest shortcoming of high water-sealed floor drain. I am long, generally around 15cm, and the manufacturer's warranty is 2 years.
Coreless floor drain was born after long-term research and continuous innovation by professional and technical personnel. It skillfully uses the principle of gravity balance to solve many problems, obtains national patents, and leads the industry in comprehensive performance, and has been tested and confirmed in long-term engineering practice.
1, straight-through drainage, water directly flows into the sewer pipe, and the displacement is 1.3/ s (national standard 1.0 L/s), which avoids the deposition of stolen goods in the trap of water-sealed floor drain and causes secondary pollution.
2. Using the gravity of water flow to open and close, there is water opening and no water closing; Stepless speed regulation, fully sealed; Gravity as the source, stable performance. It will not seal the floor drain like a spring or a magnet, and the elastic force or magnetic force will gradually decrease and eventually fail.
3. All the joints of the sealing core, gasket and shell of the washing machine are equipped with sealing aprons to ensure that there is no chance of odor and pests.
4, metal cover plate, plastic perforated strainer double filtration, to prevent large debris blocking the sewer pipe.
5. The invention is suitable for the drainage pipes of washing machines with various calibers, and solves the problems of large instantaneous displacement of washing machines and overflow of water to the ground. After being removed, it can be used as a common floor drain.
6, easy to clean, the plug-in sealing core only needs to be pulled out by rotation and scrubbed in water.
7. The main body is made of 304 stainless steel or high-quality brass, carefully processed and electroplated, and the sealing core is made of high-quality engineering plastic, which has the advantages of high temperature resistance of 80℃, corrosion resistance, environmental protection and long service life.
8. Save the trap pipe at the lower part of the pipeline, save the cost of materials, installation and decoration, reduce the neighborhood disputes during maintenance, and create an economic and harmonious society.
9, low installation height, suitable for the same floor drainage system.
10, the old floor drain is easy to replace and will not damage the ground and waterproof layer.
