Conserving water resources is something that everyone should do in our daily life. In addition to paying attention to behavioral measures, we must also keep up with hardware facilities, such as faucet aerators. Do you know what a faucet aerator is? Does it work? 1. What is a faucet aerator The principle of the bubbler is actually very simple, that is, it can fully mix the water and air flowing through it, so that the water flow has the effect of foaming. Use water. Generally, the water flow of high-end faucets is soft and comfortable like mist, and it can also filter impurities in the water, and it will not splash around. 2. The function of the faucet aerator 1. Water saving The bubbler can fully mix the water and air flowing through it to form a foaming effect, improve the flushing force, and thus reduce the water consumption. The faucet with the bubbler can save about 50% of water compared with the faucet without the device. . 2, splash-proof, noise reduction After mixing in the air, the water flow is soft, the impact force is reduced, the water column after buffering is uniform, and the water column vertically reduces the splash. 3. Filter The multi-layer filter screen can filter most of the sediment and impurities, and the internal grid can filter large particles of impurities (occasionally blocked and needs to be cleaned). 4. Constant water flow/water output With pressure compensation or flow limiting device (common in showers), it can ensure a certain water output when the water pressure is too low, limit the water output when the water pressure is too high, and stabilize the water output when the water pressure is unstable.

The metal material used to make the kitchen faucet is immersed in water for a long time, and ions are continuously precipitated, which seriously affects the water quality. This paper expounds the index of heavy metal precipitation in the faucet and the mass percentage of heavy metals in the raw materials of the faucet, and points out through experiments that the metal material of the faucet affects the quality of the tap water, and the first 3-5L of the overnight tap water is not suitable for drinking. It is recommended to use safe and high-quality drinking water faucets. The faucet in the home kitchen is one of the main products of the bathroom water supply. The water flowing out of the faucet is either heated for drinking, cooking, brushing teeth, washing vegetables, fruits, and clothes, which is closely related to people's daily life. As people pay more and more attention to health and food safety, the precipitation and precipitation indicators of heavy metal ions in water from faucets have become important environmental health and safety indicators that people and the industry care about. 1. Precipitation of heavy metals from faucets ⑴. Precipitation of heavy metal ions. The faucet is composed of materials such as metal, ceramics and plastics. The metal contains a lot of heavy metals such as zinc and copper. A small amount of lead added during processing is segregated on the inner and outer surfaces of the faucet. The water in the faucet will destroy the surface of the lead washing, forming "corrosion", and the lead ions inside are exposed, resulting in a certain degree of lead precipitation and dissolution into the water, especially the "overnight water" retained in the water pipe, which has a higher content of heavy metals. ⑵. Heavy metal ion precipitation index. It refers to soaking water prepared with close to real tap water components under the condition of eliminating the interference of heavy metals and other harmful components, and using soaking water according to the soaking procedures and methods specified in the standard to soak the surfaces in the faucet that are in contact with water. Finally, the precipitation of heavy metals in the soaking water was tested. The heavy metal precipitation index has a great correlation with the mass percentage of the faucet manufacturing raw materials. Usually, the level of the heavy metal mass percentage will determine the level of the precipitation index. 3. Relevant standards for heavy metal precipitation ①.Basic standard. GB 5749-2006 "Standard for Drinking Water" is a full-text mandatory national standard, which includes the sanitary requirements for drinking water quality in my country and the sanitary requirements for sanitary and safe products of drinking water. ③.

The working principle of the thermostatic faucet is to use the temperature sensing element inside the valve core. This temperature sensing element is made of paraffin or Nitinol. It will change its shape according to the change of temperature, such as a component made of paraffin, when the water temperature changes, the volume of paraffin changes, and then the valve core ratio is adjusted by controlling the shaft, so that the water temperature can be adjusted to maintain a certain value. The temperature remains unchanged to achieve the effect of constant temperature water. First, the working principle of the thermostatic faucet The working principles of thermostatic faucets and thermostatic showers are similar. They all have a valve core, and this valve core has a temperature sensing element. This temperature sensing element is made of paraffin or Nitinol. It will change its shape according to the change of temperature, such as a component made of paraffin, when the water temperature changes, the volume of paraffin changes, and then the valve core ratio is adjusted by controlling the shaft, so that the water temperature can be adjusted to maintain a certain value. The temperature remains unchanged to achieve the effect of constant temperature water. The valve core of the thermostatic faucet is very precise, so the premise is that the water quality must be very good. Poor water quality will affect the sensitivity of the valve core. When purchasing a thermostatic faucet, there are generally two filters installed in the water nut to filter impurities. The function of the thermostatic faucet can only maintain a constant water temperature, it does not show the water temperature and the size of the water temperature; the scale of the handwheel of the faucet can only be an approximate value, which is inaccurate. Normally, the thermostatic faucet has overheat protection, which is about the 38° scale line. If you want to increase the water temperature, you must press the raised button to turn the handwheel. Second, the installation and precautions of the thermostatic faucet 1. When the water pressure of hot water and cold water is too different, use a screwdriver to adjust the valve of the bracket. 2. The tap water contains powdery sediment or soft foreign matter, which will reduce the sensitivity of the thermostatic valve core and shorten the service life of the thermostatic faucet. 3. The hot and cold water supply pipes must not be installed wrongly, the hot water pipe must be on the left, and the cold water pipe must be on the right. 4. Clean up the site before installing the thermostatic faucet to avoid small sand and stone blocks from damaging the rubber ring, thread, thermostatic valve core and other parts of the faucet. 5. The thermostatic faucet itself has no heating function, please adjust the water temperature of the water heater to 60°C ~ 85°C. 6. After use, it is best to adjust the water temperature adjustment knob on the left to below 40°C. T...

Hot water faucet safety - what is a hot water faucet The structure of the hot water faucet is very simple, including the faucet body and the water flow control switch. The faucet body is provided with a heating chamber and a control chamber, which are separated by a sealing plate to ensure safety. The control chamber is provided with a heating circuit, and the heating chamber is provided with a heating tube. The power of the heating tube is generally 2-3KW, and the hot water can be heated in 5-10 seconds. Hot water faucet safety - about the safety of hot water faucets These products generally have overheating protection, the temperature is between 30-55 degrees, and just like when we take a bath, we slowly adjust the temperature to a suitable state, and it is impossible to adjust the faucet to the maximum temperature as soon as it comes up, so Basically, there is no need to worry about scalding; in addition, the power of electric hot water faucets is generally around 2800-3500 watts, which is much smaller than that of electric water heaters. As long as it is not an old house, the general household line can meet the needs of more than 2.5mm. It is enough, the circuit load is not big. Many friends are more worried about whether the hot water faucet will conduct electricity. In fact, many hot water faucet products now have a better measure to prevent leakage, that is, "water and electricity isolation". The safety of the hot water faucet also lies in the insulating material. At present, a new type of insulating and heat-conducting material, magnesium oxide powder, is used. It has the characteristics of high density, ultra-fineness, and sufficient filling, so that the electrified heating body can be reliably separated from the outer wall, so that it can be completely separated from the water. Electrical isolation. Moreover, the hot water faucets of big brands have the main body grounding, double anti-dry-burning design and high-sensitivity leakage protection devices. Of course, consumers should pay attention to the question of whether the hot water faucet is safe: you must buy products that have mandatory 3C certification for national product quality; operate in strict accordance with the instructions; the machine must be connected to an effective ground wire; at home If there is no air switch, it is recommended to use a leakage protection socket.

1. Before installation, it should be confirmed that there are no blisters on the surface of the product, the wall thickness of the threaded pipe is uniform, and the switch can be rotated flexibly. Before installation, the water pipe should be dredged with water once to confirm that there is no garbage and residue in the water pipe, so as not to affect the water flow. 2. Pay attention to the winding direction. Take the angle valve as an example. When the angle valve is screwed into the inner thread of the wall, it rotates clockwise to the right. Then the direction of wrapping the remaining tape on the angle valve is counterclockwise to the left. Winding, so that when the angle valve is twisted, it will be tightened more and more tightly, and it will not loosen. 3. Tighten the raw material tape when wrapping, so that the raw material tape is tightly attached to the thread, try to be as tight as possible, and do not wrap it loosely. 4. There is no hard and fast rule for "several layers" of winding, which can be tightened without leakage. However, according to experience, it is usually necessary to wind more than ten times to ensure the sealing effect. 5. When screwing the thread, don't screw it to the dead end. Use a little bit of strength. You don't have to screw it until it can't be screwed. It only needs to feel strong when screwing. Also pay attention to the depth of the screw in. Angle valve installation precautions 1. When installing the angle valve faucet, the place where the raw material tape should be wrapped is less: I feel that it is almost enough to wrap it three or five times, and the result is always leaking. 2. When installing the angle valve faucet, wrap the raw material tape violently at the place where the raw material tape should not be wrapped: the place where the wire is connected to the hose, the two ends of the shower hose, etc., the more it is wrapped, the more water will leak. 3. The leak test was not careful: it didn't leak at the time, but it should be observed several times after that. The water is fine, but the gas should pay special attention. The gas pipeline should be brushed with soapy water on the connecting parts and joints, and the foaming should be found in time. deal with. 4. The hose (braided hose and corrugated hose) is unnaturally stressed and unnaturally bent: the hose joint cannot be bent within 5 cm from the joint, cannot be beaten to death, cannot be under constant stress, etc., under these morbid conditions Hose life will be greatly reduced.

At present, there are many styles and varieties of stainless steel water basins on the market, and the quality is uneven. To identify the quality of a water basin, we must first look at its material. Now high-end stainless steel water basins are made of SUS304 material. Kitchen sinks and faucets are a must for every kitchen cabinet and are used very frequently. Therefore, the quality of the water basin and faucet is very important, and at the same time, the practicability and aesthetics of the water basin, as well as the matching between the faucet and the water basin should be considered. The kitchen sinks on the market can be roughly divided into three categories: stainless steel, artificial stone and ceramics. Among them, the proportion of artificial stone and ceramic basins is very small, and stainless steel basins are currently the main ones. Stainless steel material has the characteristics of lightness, environmental protection, durability, strong corrosion resistance, good texture, etc. At the same time, it has good stiffness and toughness, and can create different styles of shapes. At present, the double-slot shape is commonly used, and the size is generally about 800×420×200mm, which is moderate in size and easy to use. In addition, the configuration of water basins is becoming more and more abundant, and the functions of use are greatly increased, including the application of auxiliary products such as trash cans, automatic drainage devices, draining baskets and cutting boards, so that the water basin gradually changes from the original single washing function to the food cooking center. This role transition. There are many styles and varieties of stainless steel water basins on the market, and the quality is uneven. To identify the quality of a water basin, we must first look at its material. Now high-end stainless steel water basins are made of SUS304 material. When it comes to materials, many consumers have a misunderstanding - it is a magnet to judge whether the basin is stainless steel, in fact, this is not scientific. Due to the process of stamping and stretching in the production process of stainless steel, the local molecular structure has changed, resulting in the generation of magnetism. For example, due to the large tensile stress at the corner of the basin, its magnetism is relatively strong, which means that stainless steel is not completely non-magnetic, and it is not stainless steel if it is magnetic. Secondly, whether the size of the water basin conforms to the size of your own cabinet structure, and whether the size and division ratio of the water basin is appropriate, and finally you can appropriately choose other functions of the water basin according to your own preferences. There are more styles and varieties of kitchen faucets currently on the market. Consumers generally pay attention to the following three points when purchasing: First, due to the high frequency of use of faucets, the core component is the valve c...
