What is a ceramic cartridge? The cartridge is a part of the faucet and plays a vital role. The cartridge is made of ceramics, brass, etc. So, which is better, ceramic valve core or brass core? Let's find out together. What is a ceramic cartridge The ceramic cartridge is actually a part of the faucet. The use of the ceramic cartridge is actually the water flow controller of the faucet. The introduction and closure of the water flow is controlled by the rotation of the ceramic scartridge. Moreover, the quality of the ceramic valve core is good, and the firmness of the ceramic valve core is high, it is not easy to loosen, and there will be no water leakage. The water outlet of the ceramic valve core is relatively smooth, and there will be no water interruption. In the family, if the cartridge of the faucet used is not good, it will affect the water quality, and the ceramic spool is a natural material that will not affect the human body. Ceramic cartridges are used in faucets, and generally include three different usage situations: vegetable sinks, wash basins, and shower faucets. Therefore, the prices of ceramic spools are also different. Which is better, ceramic cartridges or copper cartridges? The faucet cartridges used in households are mostly made of ceramic cartridges, including hot and cold water mixing valves, such as cartridges for sinks, basins, and shower faucets. Ceramic cartridges are widely used. Only some old-fashioned single-cooling faucets and commonly used valves still use copper valve cores. Compared with copper valve cores, ceramic valve cores are more wear-resistant, and ceramic valve cores will not rust and affect water quality. At the same time, the quality of the ceramic valve core is very good, relatively firm, it will not loosen, and there will be no water leakage, and the water will flow more smoothly, and there will be no water interruption. In the past, some iron and copper faucet spools would leak due to wear and tear during use, and now they have basically withdrawn from the faucet market. Selection skills of ceramic valve core 1. Look at the feel. When purchasing a ceramic cartridges, it depends on the feel of the faucet switch. The ceramic cartridges with good sealing performance has a good resistance to opening times, and it will not cause the faucet to drip due to the wear of the cartridges. Using high-quality ceramic valve core, the faucet feels good, and the opening and closing are smooth and comfortable. 2. Look at the coating. The coating of the faucet is also very important. After the faucet is ground and polished, the surface should be plated with nickel or chrome to prevent the faucet from being oxidized. After nickel or chrome plating, the faucet can be subjected to a medium-sized hydrochloric acid test to see whether the faucet is corroded within a certain period of time. 3. Look at the quality inspection certificate. When choosing a faucet, it is best to ask the salesperson for a faucet quality inspec...

Faucets are often used in daily life, which is very convenient and practical. However, how does a booster faucet work? Let's find out together. The working principle of the pressurized faucet: Through a configuration, the faucet nozzle is squeezed into the air, and the external pressure of the air increases the water flow with the same amount of water. The pressurized faucet adopts the principle of variable diameter current-carrying pressurization. When the pressure of the tap water is high, the water it sprays will not sting the skin. The pore size of 0.2 and the pressure of more than 100 holes are dispersed naturally and become very soft when passing through the sprinkler sheet. When the water flow enters the nozzle base, it is pushed into a three-wing accelerator to make the water flow rotate to increase the speed and momentum of the water flow. It then goes directly into a restricted water channel, where the air and water mix increases the oxygen content by a factor of 10. This not only achieves the purpose of saving water and energy, but also brings a satisfying bathing experience. The pressurized faucet can intelligently limit the flow, and automatically adjust the water inlet area according to the water pressure. When the water pressure is small, the water inlet area is opened to make the water volume balance, which can not only increase the pressure, but also save water. According to the size of the water pressure, the water inlet surface area is automatically changed. When the water pressure is small, the water inlet area is turned on. In this way, the water output reaches a balance, which achieves the purpose of supercharging. Choose D & S Faucets, we will provide you with the best service.

Is the pull-out faucet good? advantage: Convenience: We all know that the water outlet of traditional faucets is fixed. Usually, it is very inconvenient to use relatively large objects to receive water, such as basins, buckets, etc., but the pull-out faucet can properly solve this problem. . User-friendly: The pull-out faucet can pull out a stainless steel hose with a maximum length of 1.5 meters from the nozzle position, the rotation angle can reach 360 degrees, and the spout can easily reach the place where you need to flush or use water. Whether you want to add water for cooking, watering flowers, or washing dishes, the water flow can easily reach you. You can really wash wherever you want. With a single touch, you can flexibly change the shower water and faucet water, and easily solve the problem of cleaning in the kitchen. any question. Easy to clean: Due to the cooking habits of Chinese people, the kitchen fumes are large, so the faucet is easily stained with oil and water stains, and after repeated cleaning, the surface of the faucet is easy to lose its luster. However, the pull-out faucet will not have such a problem. With special coating treatment technology, the cleaning agent does not fade, does not corrode, is not easy to stick to oil, easy to clean and wear-resistant. Durability: Professionals say that the durability of the faucet mainly depends on the surface treatment process. It was tested in an acidic high temperature environment with a pH value close to 3, and it remained intact for more than 4 hours, indicating that the surface treatment process is very good, and the pull-out faucet reaches this level. a standard. Environmental protection: The environmental protection of the faucet is reflected in the lead content in the water, which is mainly caused by the scouring of the waterway by the water body. The low-temperature welding process is used between the under-counter copper water inlet pipe and the faucet body to maintain the high strength of the product, and special welding materials are used, which do not contain cadmium and effectively eliminate harmful metals. Disadvantages: First, will the pull-out faucet rotate easily. In fact, when the pull-out faucet is not picked up, no matter how it is swayed, it still rotates at the bottom, because the pull-knot is inserted by the curved fittings, and it can only be picked up and cannot be rotated. The second is that the pull-out faucet is often pulled. Will the stainless steel hose become knotted or hardened, or even damaged, and the faucet is not easy to put in place? During the production of the pull-out faucet, a heavy drop is designed on the hose. , When not in use, put it directly, the hose will be reset naturally, if the hose is not intentionally bent, there will be no problem, the stainless steel outside is of good quality, and the hose inside is naturally not easy to be damaged.

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. Product standards. Mainly include: GB18145 "Ceramic Sheet Sealing Faucet", QB1334 "General Technical Conditions for Faucet".
