The size switch used to control the water flow has the function of saving water;
1, which can be divided into SUS304 stainless steel, cast iron, all plastic, brass, zinc alloy faucet, polymer composite faucet and other categories according to materials.
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 (slow opening valve core), ceramic valve core (quick opening 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 relatively common; Stainless steel valve core is more suitable for areas with poor water quality.
How to choose a faucet:
1. Turn the handle: it feels like a light valve core. Common faucet valve cores include steel ball valve cores and ceramic valve cores. The steel ball valve core has good pressure resistance, but the disadvantage is that the rubber ring that plays a sealing role is easy to wear and will soon age. Compared with the steel ball valve, the ceramic valve core is more heat-resistant and wear-resistant, and the ceramic valve itself has good sealing performance, so it can achieve a high number of times of opening resistance, and the water nozzle will not leak because of the wear of the valve core. The faucet with ceramic valve core is also more comfortable and smooth, and the switch is quick. Because the valve core is inside the faucet, consumers can't see the valve core when they buy it, but they can simply judge the quality of the valve core according to the feel when turning the handle. Generally speaking, if the consumer turns the handle up, down, left and right, it feels lighter and there is no sense of jamming, indicating that the valve core is better.
2. To test books: the quality is more secure. The faucet body is usually brass. The electroplating quality of products made of brass can be best guaranteed. The higher the purity of brass, the better the electroplating quality, and the less likely the electroplated layer on the surface will be corroded. In order to reduce costs, some manufacturers choose zinc alloy instead of brass. Although the country allows zinc alloy to replace brass, zinc alloy electroplating quality is poor and corrosion resistance is not strong. Consumers can use the method of weight estimation to identify when buying. Brass is heavier and harder, and zinc alloy is lighter and softer. However, experts in the main materials department of Kuoda Decoration believe that the quality of faucets can not be seen only by weight, "because some manufacturers can make faucets heavier by increasing the wall thickness of faucets or adding other metal materials". Consumers had better ask the sales staff for the product inspection report. If the test report determines that the product is qualified, it is "not a big problem".
3. Test water flow: Rich and soft foam means that the bubbler is better. Consumers should choose a more durable integral casting faucet. The sound of the integrally cast faucet is more dull when it is tapped, and consumers can judge whether the faucet is integrally cast by tapping the faucet when purchasing. When purchasing, you should try to choose a faucet with a bubbler and feel the water flow with your hands. The water flow is soft and the foam is rich (the bubble content in the water flow), which shows that the quality of the bubbler is good. The bubbler usually has six layers and usually consists of a metal mesh cover (partly plastic). When the water flows through the net cover, it will be cut into a large number of small water columns with air in the middle, so that the water will not splash around.
4. Brand recognition: choosing brand after-sales service is more secure. Consumers should buy brand faucets in regular markets and supermarkets. Brand goods have the brand logo of the manufacturer, and irregular products or inferior products often only have some paper labels or even no logo. The faucet box should also have the manufacturer's brand logo, quality guarantee and after-sales service card.
lavatory
