How to select a kitchen water faucet with good quality, there are many suggestions for reference:
At present, the leading control handles are mainly divided into spiral type, single handle, double handle, and several types with 90° switches.
The tap control handle has a single handle and a double handle. The single handle is characterized by easy control and simple structure. The double handle requires both hands to adjust the water temperature, but the style can be used for more occasions (such as under-basin faucets, cylinder head mixers for massage bathtubs, etc.), and the double-handle faucet adjusts the water temperature. More smooth and delicate than a single handle, suitable for consumers who are more sensitive to temperature. When the single-lever faucet is turned on and off, the water pressure will rapidly increase. If the copper content of the product is not high enough to withstand the expansion of the water pressure, it is easily damaged. Therefore, when the single-lever faucet is in use, it should be slowly opened and shut down. The double-handle faucet has a large pressure range and the water pressure is slowly released, so there is no such problem. However, the double-handle mixer cannot be closed too dead, otherwise it will cause the sealing plug to fall off, causing it to stop and stop the water.
With a 90° switch, on the basis of the traditional double handle, the original rubber seal is changed to a ceramic seal. When the handle is opened and closed, the handle can be rotated 90°, and it can be adjusted on both sides of the cold and hot water. Its characteristic is easy to open. There are more styles.
The traditional spiral-rising rubber-sealed faucet is still welcomed by some consumers because of its large amount of water, low price, and easy maintenance.
From the opening method, there are mainly the following:
When the spiral handle is opened, it needs to rotate a lot of circles and basically has been eliminated; the wrench handle is generally rotated by 90 degrees; the lifted type handle only needs to be lifted up to be able to discharge water; the induction type tap only needs to reach under the faucet. Will automatically out of water. In addition, there is also a time-delayed faucet. When the switch is closed, the water will flow for a few more seconds before stopping, so that the dirt on the hands of the faucet can be flushed again. Consumers can choose the right handle according to their needs or refer to our single shopping guide.
Not all taps have bubblers, but generally better taps will have this structure. The main function of the bubbler is to prevent the flow of water from diffusing and to make the flow relatively straight. The intuitive feeling is to play a small bubble in the hand and it will not splash everywhere, and it also has a certain water-saving function.
The bubbler of many brand products has a certain filtering effect and can filter particulate impurities in tap water. If the water quality in the area is not good, the faucet water will gradually become less, and the bubbler can be opened and returned to normal after cleaning. A good bubbler is made of high-quality stainless steel mesh and can be seen.
When purchasing, it is best to choose a faucet with a bubbler. The water flow is soft and foamy (water bubble content) rich, indicating that the bubbler quality is better. The bubbler generally consists of six layers, usually consisting of a metal mesh cover (partly plastic). When the water passes through the mesh cover, it is cut into a large number of tiny water columns with air interposed in it so that the water does not splash around.
There are three common spools: ceramic spools, stainless steel balls, and shaft roller spools.
Ceramic valve cores are widely used due to their low price, low water pollution, good wear resistance, good sealing performance, and improvement of “brittleness”. In general, the ceramic valve core plays a very good sealing role. Due to the relatively strong foreign technology, some imported ceramic chips have relatively better sealing performance, stable physical properties, wear resistance and long service life. Most of the mainstream mixers produced by most well-known brand sanitary ware manufacturers on the market have adopted ceramic valve cores.
The advantage of the shaft roller valve is that the handle rotates smoothly, the operation is easy and convenient, the handle is comfortable and relaxed, and the anti-aging and anti-abrasion resistance is achieved. However, the shaft-roller spool, as an old-fashioned spool, has gradually failed to meet the demand of the crowd for the spool, and will be gradually eliminated by the market. Roller spools are now rare in the big brands.
The stainless steel ball valve is a leading valve element with a relatively high technological content. Some high-grade bathroom brands adopt the irregular seven-hole steel ball valve core processed by laser technology as the valve core of its latest faucet products. The industry also believes that this kind of spool is more suitable for areas with poor water quality, because it is not affected by impurities in the water and will not shorten the service life. Moreover, the handle of the steel ball valve core has a larger angle in the area of adjusting the water temperature, which can accurately control the water temperature and ensure that the hot water flows out quickly and accurately, and has the effect of saving energy. However, the production cost of the stainless steel ball valve core is higher than that of other types of valve cores. At the same time, the production process is more delicate and suitable for applications where the water quality environment is poor.
The faucet spool discriminates "simple method"
1. Switch the faucet handle and feel it by hand. It is better to feel uninterrupted when switching up and down.
2. Turn the valve switch halfway and stop. Then hit the spot! Compare it with the feeling, the upper and lower half feel the same is better.
3. When the valve core is left and right (adjusting cold and hot). (First use the above method) Then look at the weight, when the good spool is around, it is "idle", and the hand is very light.
4. Use the index finger and middle finger to gently grip the handle of the faucet, move it up and down and left and right to see if it is flexible and loose, whether it blocks the hand feeling, whether it has the feel of oil damping, flexibility is not loose, and the feel is not blocked. Heavy oil damper feels better.
How to distinguish the plating quality is good or bad? There are a few small ways: in the case of adequate light, carefully watch the quality of the faucet plating, good plating without any oxidation spots, scorch marks, no air holes, no blistering, no Leakage plating, uniform color; touch without burr, sand; tap the finger with the tap, the fingerprint quickly spread, and not easy to attach dirt. Or, the consumer can use his mouth to breathe into the surface of the faucet and the surface of the faucet immediately forms a layer of moisture. Plating good quality products, water vapor will quickly and evenly fade away, poor quality products, water vapor fade will be slower, and even coagulation does not fade, water vapor fade faster and more uniform, indicating that the plating quality is better. The main purpose of electroplating is to decorate and prevent rust, but it does not mean that irrespective of it will never rust, especially where it is often exposed to the human body. However, cleaning the plating parts with car wax once a month can effectively protect the plating of the faucet.
With the development of modern water taps, with the development of economy and science, there have been various taps with cast iron, plastic, copper, alloy, ceramic, stainless steel and other materials. Among them, the cast iron faucets have gradually been eliminated, and all-plastic faucets are mostly used in special fields. Nowadays, household faucets most commonly contacted include copper, alloys, ceramics, and stainless steel faucets. Alloy faucets have become more and more out of sight because they are harmful to health. Although ceramic and stainless steel taps have their own advantages, they are usually expensive and difficult to process, so the types and quantities of products are less. All-copper faucets occupy the leading position of the leading materials market with its excellent cost-effectiveness.
(1) copper faucet
Pure copper faucets are made of pure copper, chrome-plated on the surface, with high gloss and high anti-wear and anti-corrosion properties. Mainly in its own copper content and process to distinguish the quality of the pros and cons. The copper used in the plumbing industry is mainly 59 copper. In addition to copper, there are other metal contents that can be detrimental to human health if the amount of lead is too high. The lead content of many faucets on the market is generally between 3% and 5%. In response to this situation, some manufacturers have developed low-lead faucets with lead content below 0.3%. In view of the fact that lead content is difficult for ordinary consumers to judge, and internationally there are strict rules for the lead content of pipeline products, it is best to purchase taps that have passed relevant certification for their own health. (Small TIP: When you get up in the morning, you can turn on the tap for half a minute, letting the water out of the tap and avoid taking in excess lead.)
(2) alloy faucet
The price of alloy faucets is much lower than that of copper faucets, and this faucet is easier to produce on a large scale. Among them, zinc alloys are widely used, and zinc alloy faucets are harmful to the human body and are not very durable. At present, zinc alloys can be used as faucet handles and some bathroom hardware accessories. As the zinc alloy plating process is very mature, and some manufacturers will specifically increase the weight of the zinc alloy faucet, it is difficult to distinguish it from the copper faucet by weight and appearance. For your health, it is still advisable to purchase a faucet that has passed the relevant certification and evaluation agency evaluation.
(3) ceramic faucet
Ceramic faucets, as the name suggests, are the leading ceramic makers. Compared with other faucets, ceramic faucets have the advantages of no rust, no oxidation, and no wear. Ceramic faucets look beautiful, because the shell is also ceramic products, so it can be matched with the bathroom products, adding the artistic sense of ceramic products, bring out the bathroom upscale temperament.
(4) stainless steel faucet
Stainless steel faucets do not contain lead, and are resistant to acids, alkalis, corrosives, harmful substances, and sources of tap water. It is understood that the current 304 stainless steel faucet surface does not need to be electroplated, its surface only need to be polished can show the true nature of stainless steel, and can continue to maintain the silver-white luster, never rust, stainless steel, hardness and toughness are higher than copper products 2 times more. However, the hardness, toughness, melting and cutting of stainless steel are much more difficult than copper and the cost is high.
