1, according to the material can be divided into SUS304 stainless steel, cast iron, all plastic, all copper, alloy faucet, polymer composite faucet and other categories. 2, according to the function, can be divided into basin, bathtub, shower, kitchen sink faucet. 3. According to the structure, it can be divided into single tap, double tap and triple tap. In addition, there are single handles and double handles. Single connection can be connected with cold water pipe or hot water pipe; Double-type hot and cold pipes can be connected at the same time, which is mostly used for faucets in toilet basins and kitchen vegetable basins with hot water supply; In addition to connecting hot and cold water pipes, the triple type can also be connected with a shower nozzle, which is mainly used for the faucet of a bathtub. Single-handle faucet can adjust the temperature of cold and hot water through one handle, while double handles need to adjust the cold water pipe and hot water pipe respectively to adjust the water temperature. 4. According to the opening mode, it can be divided into screw type, wrench type, lifting type and induction type. When the screw handle is opened, it should be rotated several times; Generally, the wrench handle only needs to be rotated 90 degrees; Only by lifting the handle upwards can the handle be removed; As long as the induction faucet reaches under the faucet, it will automatically come out. In addition, there is a faucet with delayed closing. After the switch is turned off, the water will flow for a few seconds before stopping, so that when the faucet is turned off, the dirty things on your hands can be washed clean. 5. According to the valve core, it can be divided into rubber valve core, ceramic valve core and stainless steel valve core. The key to affect the quality of faucet is the valve core. Rubber core faucets are mostly cast iron faucets with spiral openings, which have been basically eliminated; Ceramic valve core faucet appeared in recent years, with good quality, and it is more common now; Stainless steel valve core has only recently appeared, which is more suitable for areas with poor water quality. 5. Faucet water purifier The main water purification technologies used in faucet water purifier are as follows: (1) Activated carbon technology Fujian Tian Bing Water Purifier believes that activated carbon is the main water purification material of faucet water purifier, and nano-active filter element has better adsorption capacity, which has better filtration effect on chlorine, heavy metals and pesticides in water before adsorption saturation. (2) Hollow fiber technology Toray and Mitsubishi Liyang in Japan and Jiayou Water in China adopt hollow fiber membrane-based water purification technology, which can filter out most pollutants in water and need to replace the filter element regularly. (3) Ceramic and nano-KDF technology Most domestic products use water purification technology mainly composed of microporous ceramic filter core and nano-KDF filter material, dechlorination ball and alkaline ball, and the effluent flow is greater than that of water purifiers using hollow fiber technology. Ceramic filter element can be cleaned and used repeatedly, and it needs to be replaced regularly after reaching a certain service life.

1 Cleaning (1) Don't wipe the surface of the faucet directly with a wet towel (2) Don't wipe the faucet with burrs (3) Don't let the faucet come into contact with acid and alkali liquid (4) Don't put the faucet directly on hard objects (especially when showing it to customers, don't put it directly on our table. Give customers a feeling that your products are not high-grade) (5) Wipe with a dry and soft cotton cloth. 2) Maintenance (1) Usually, you can spray car wax on the faucet surface for 3-5 minutes and then wipe it, so as to keep the faucet sample bright. (2) At ordinary times, it is best not to touch directly with your hands, because the oil stains on your hands are easy to get on the surface of the faucet, and it is not easy to clean it, which affects the smoothness. (3) Changing the location of faucet samples frequently (4) Changing faucet samples frequently can adopt the following two methods: a, replacing the sold faucet samples with new boxes and taking them away from customers; B, exchange samples with the company's goods, and the company's delivery staff will send the samples to consumers' homes for installation.

[Edit this paragraph] Production process

The production process of faucet: copper ingot → dissolution → casting (low-grade faucet is cast with casting sand and high-grade faucet is cast with gravity) → cleaning after casting → casting inspection → machining → tolerance inspection → leakage test → polishing → surface inspection → electroplating inspection → assembly → water test and leakage test → finished product inspection → packaging → delivery. Casting: low-grade faucets are cast with sand, and high-grade faucets are cast with gravity. The relatively new technology is die casting, which is similar to the current zinc alloy die casting process. Quality control: the quality of the production process before the finished product is controlled by quality control, and the sampling inspection from the later cost to the packaging is carried out by the quality assurance department, mainly to check the packaging and placement of the products. The well-known imported brands in the market are Delta, Moen, Kohler and American Standard in the United States, Hansgroya and Gaoyi in Germany, Spanish musicians, TOTO in Japan and Coma in Australia. Well-known domestic brands include Jiumu, Zhongyu, Shenluda, Huang Hui Plumbing, Huida, Wrigley, Eagle, Zhong Tao and so on.

[Edit this paragraph] Precautions

Common sense of hardware accessories: 12 points for attention when choosing a faucet: you can't buy a faucet that is too light. Too light is mainly because the manufacturer hollowed out the copper in order to reduce the cost. Faucets look big and are not heavy to carry, which makes them more susceptible to water pressure bursting. Handle: the composite faucet is very easy to use, because only one hand is empty when using the sink. Water outlet: the high water outlet is convenient for basin irrigation. Valve core: This is the heart of the faucet. At present, hot and cold faucets all adopt ceramic valve cores, and the best quality of valve cores are Spanish Circuit, Taiwan Province Kangqin, Zhuhai and other brands. Rotation angle: it can rotate 180 degrees, which is convenient for work, while the rotation of 360 degrees is only meaningful for the sink placed in the center of the house. Expandable shower head: increase the effective radius, and the sink and container can be filled more quickly. Hose: Experience shows that 50 cm long pipes are enough, and pipes over 70 cm can also be bought in the market. Be careful not to buy aluminum tubes. Use stainless steel wire. Hold it tightly in your hand and pull hard. When your hand turns black, it will be aluminum wire, but it will be stainless steel wire without change. It is best to use a stainless steel hose woven with five international standard threads outside. The inner tube of the hose is made of EPDM, the connecting nut is made of red stamping forging, and the outer surface is plated with 4miu (thickness) nickel layer. Shower pipes: In order not to make unpleasant noise, try to avoid using metal pipes. Anti-calcification system: calcium will deposit in shower heads and automatic cleaning systems, and the same thing will happen on faucets, where silicon will gather. The integrated air filter has an anti-calcification system, which can also prevent calcification inside the equipment. Anti-backflow system: This system prevents dirty water from being sucked into the clean water pipeline, and is composed of multiple layers of materials. Equipment equipped with backflow prevention system will display DVGM passing sign on the packaging surface. Cleanliness: Streamlined design does not require too much cleaning. When cleaning, do not use detergent or nylon brush with coarse particles such as decontamination powder and polishing powder. Wipe with a proper amount of diluted shampoo and shower gel, rinse with clear water, and then wipe the faucet with a dry soft cloth. Material: stainless steel, health and environmental protection. Chromium burning equipment is easy to care for and harmless to people, but other elements need to be added in the manufacturing process. So be sure to pay attention to what material the equipment is made of. Not all countries have such high standards as Germany. Durability: Anti-calcification system can prevent equipment from leaking and handling damage. Maintenance: In terms of maintenance costs, there are great differences among various types of equipment, and the materials of some equipment are not easy to obtain. The repair is actually quite simple, just need to have the corresponding accessories, of course, there must be a structural diagram, otherwise I don't know how to put it back.

[Edit this paragraph] faucet purchase method

It is very particular to see a good-looking chrome plating process on the faucet surface, which is usually completed through several processes. Distinguish the quality of a faucet by its brightness. The smoother and brighter the surface, the better the quality. Turn the handle well. When turning the handle, there is no excessive gap between the faucet and the switch, and the switch is free and does not slip. Inferior faucets not only have a large gap, but also have a great sense of obstruction. Listening to the sound, the material of the faucet is the most difficult to distinguish. A good faucet is made of copper as a whole, which makes a dull sound when knocking. If the sound is crisp, it must be stainless steel, and the quality will be one grade worse. If you really can't tell, you can choose a more formal brand. Generally, regular goods have the brand logo of the manufacturer, while some irregular products or some inferior products often only have some paper labels or even no logo, so you must pay attention when buying.

[edit this paragraph] faucet leakage treatment method

In daily life, it is sometimes found that the water in the faucet will still drip down after tightening, and it will drip down from the outlet or joint of the faucet, which not only causes a lot of waste, but also sometimes causes some trouble. In fact, the structure of the faucet is very simple, and the maintenance of water leakage can be done by yourself. Generally speaking, the problem of water leakage can be solved by replacing the gasket parts such as axial gasket or triangular gasket inside the faucet. But before decorating, you have to turn off the main faucet switch at home. Regarding the maintenance of water leakage at the faucet joint, the reason for water leakage is nothing more than the damage of the water stop tied to the faucet part (fixing screw). Therefore, as long as the faucet is removed with a plate clamp, a new water stop can be rewound at the place where the screw is fixed. The following are the maintenance steps: firstly, fasten the faucet and rotate the faucet counterclockwise with plate pliers. Second, turn the threaded hole outwards, and turn the threaded part clockwise for 5-6 times with the wind-printed tape. See if the faucet has been adjusted and tighten it clockwise with water bolt pliers. After the final installation, turn on the main switch to ensure that there is still water leakage. Even if the faucet is fastened, it will still leak: 1. Cause of water leakage at the water outlet: the axial gasket in the faucet is worn. Loosen the gland bolt with pliers and take it off. Take out the axial gasket with a clamp and replace it with a new axial gasket. 2. Cause of water leakage in the lower gap of faucet bolt: The gland triangular gasket is worn. You can loosen the screw, take off the bolt head, then loosen the gland, and then take out the triangular seal shop inside the gland and replace it with a new one. 3. Water leakage at the nozzle joint: generally speaking, the nut is loose, so the nut can be tightened again or replaced with a new U-shaped gasket. If the tap is found to be low in water, it may be leaking, because the water stop plate of the single-gun tap is stuck by sand and gravel. This phenomenon still needs to be removed by a professional repairman, but if the rubber pad is damaged, it must be replaced. Generally speaking, the correct use of the faucet means that the faucet should not be turned too tightly. The rubber pad of the sauce faucet can be used for 7 or 8 years. However, the faucet in the hot water part is easy to shorten its life because it expands when heated and contracts when cooled. Therefore, it is generally recommended that the rubber pads on both sides of the faucet be replaced regularly at the same time.
