Identification method of 304 stainless steel faucet SUS304 stainless steel faucet have a beautiful appearance. When purchasing, you can feel no burrs, pores, spots, etc. by hand. Secondly, gently turn the handle of the faucet to see if it is light and flexible, and whether there is a sense of blockage. There are a lot of products on the market, the technical coefficient is not up to the standard, and their prices are actually 3-4 times different. Therefore, the difference in price when purchasing often reflects the difference in quality. At the same time, carefully check the parts of the faucet, focusing on whether the parts are complete and whether the main parts are assembled tightly without looseness. The next step is to inspect the material, the material of the faucet is not easy to distinguish. The real SUS304 stainless steel faucet body can only be precision-cast and welded. The precision-cast body is resistant to high pressure and has a smooth and natural appearance after polishing and drawing. The price is slightly higher; the welding interface is more rigid, and the smoothness after polishing and drawing is slightly worse. This is just a visual inspection. Generally speaking, 201, 202 stainless steel faucets and 304 stainless steel faucets cannot be distinguished only by appearance. The high credibility of companies and businesses when consumers buy is also the key to ensuring product quality. A safer approach is to contact the manufacturer's dealer or directly contact the manufacturer of the stainless steel faucet. How to maintain the faucet 1. The surface of the faucet should always be gently wiped with a soft cloth (without impurities) dipped in detergent. Avoid using metal filaments or scouring pads with hard particles. In addition, don't hit hard objects to damage the surface of the faucet. 2. Use the following cleaning agents to remove rough masks and deposits: mild liquid glass cleaner, pure liquid glass cleaner, acid-free, non-abrasive soft liquid or completely dissolved powder, non-friction solution polish . Never use any abrasive cleaners, cloth or paper cloth; never use any acid-containing cleaners, polishing abrasives or rough cleaners. 3. When the water pressure is not lower than 0.02mpa (ie 0.2kgf/cm2), after a period of use, if the water output is found to decrease, or even the water heater is turned off, you can lighten it at the water outlet of the faucet. Unscrew the screen cover gently to remove impurities, and it will generally recover. If you have interest in SUS faucets please kindly contact with D&S Faucets Company,we will provide the best quality and good service for you.

The sensor faucet is based on the principle of infrared reflection. When the human hand is placed in the infrared area of the faucet, the infrared light emitted by the infrared transmitting tube is reflected to the infrared receiving tube due to the cover of the human hand, and the signal processed by the microcomputer in the integrated circuit is sent to the pulse solenoid valve. After the solenoid valve receives the signal, it opens the spool according to the specified instructions to control the water from the faucet; when the hand leaves the infrared sensing range, the solenoid valve does not receive the signal, and the solenoid valve spool is reset by the internal spring to control the faucet to close the water. In addition, the induction faucet also has an induction water-saving faucet. It is a newly invented high-tech product widely used in high-end places such as hotels, guesthouses, and office buildings. A responsibility, with the development of induction sanitary ware, induction water-saving faucets have been widely used. AC power supply or DC power supply, using infrared sensor, water enters the sensing area, and the water stops when leaving the sensing area. The water switch is automatically completed by the sensor without touching the faucet, which can effectively avoid bacterial cross-infection. This machine adopts microcomputer control, determines the best sensing distance according to the shape of the basin, without manual adjustment, and also has a 1-minute overtime flushing and water stop function to avoid the waste of water resources caused by the sensing of foreign objects for a long period of time. The DC power supply uses alkaline dry batteries (6V, 3V, 4.5V), built-in filters to prevent impurities from entering the solenoid valve, easy to clean, beautiful appearance, firm structure, suitable for crowded places. Use function Since the induction faucet does not require direct contact with the human body, it can effectively prevent bacterial cross-infection; it has the function of watering when you reach out and shutting off when you leave, which effectively saves water by more than 30%. It is especially suitable for areas with severe water shortages in our country. Nowadays, induction faucets are widely used in public places such as train stations, bus stations, airports, hospitals, etc. with high traffic. Inductive faucets can be divided into the following types in applications: 1. Public sensor faucet---it has the function of sensing the water out of the signal and stopping the water when the signal disappears. It will automatically stop the water for a certain period of time, which is suitable for most public places. 2. Medical sensor faucet---it senses the signal to flow out, and then senses the signal to stop the water. It will automatically stop the water after a certain period of time. It is suitable for hospital operating rooms and nurses to wash hands. 3. Household sensor faucet---In addition to sensing the signal to...

Angle valves are also called triangle valves, angle valves, and angled water valves. They are mostly used in water and electricity installations in the decoration industry and are important plumbing accessories. 1. Civilian use Angle valve for heating pipe Angle valve for heating pipe The angle valve has four main functions: ① From the inside and outside the water outlet; ②If the water pressure is too high, it can be adjusted on the triangle valve and turn it down a bit; ③The function of the switch, if the faucet leaks, etc., the triangle valve can be turned off instead of the main valve in the home; ④ Beautiful and generous. Therefore, in general, new house decoration is an essential plumbing fitting, so designers will also mention it when decorating a new house. 2. Industrial use The valve body of the angle valve has three ports: water inlet, water volume control port, and water outlet, so it is called triangle valve. Of course, the angle valve is constantly improving. Although there are still three ports, there are also angle valves that are not angled. The angle valve referred to by the industry: the angle control valve is similar to the straight-through single-seat control valve except that the valve body is a right angle. Features 1. The flow path is simple, the dead zone and the vortex zone are small. With the help of the scouring effect of the medium itself, it can effectively prevent the medium from clogging, that is, it has better self-cleaning performance; 2. The flow resistance is small, and the flow coefficient is larger than that of a single-seat valve, which is equivalent to the flow coefficient of a double-seat valve; It is suitable for occasions with high viscosity, suspended solids and granular fluids, or where right-angle piping is required. The flow direction is generally bottom in and side out. Under special circumstances, it can be installed in reverse, that is, it flows in from the side to the bottom. The triangle valve has two types of hot and cold (identified by blue and red signs). Most manufacturers have the same material. The hot and cold signs are mainly used to distinguish which is hot water and which is cold water. Production Process Raw materials (copper, steel, etc.) → cut according to the amount of material used → high temperature forging → machining → polishing treatment → electroplating → assembly. the difference What is the difference between quick opening triangle valve and ordinary triangle valve: One is the rubber ring spool and the other is the ceramic spool. The quick opening is the latter, which can be done at only 90 degrees, commonly known as the quick opening type. Usually the angle valve is also used on the stove of the gas appliance. Service life Red punching and forging are more than 10 years old, and 5-8 years for foundry alloys are about 3 years. The alloy will be very brittle in about 3 years, and the pipe may be broken and cannot be replaced. Copper is easier to replace. If you have interest in...

There are many types of delay faucets, including mechanical ones and infrared ones. The time delay faucet has the characteristics of time delay, self-closing, sanitation, free from hydraulic restrictions, and significant water saving effect of 50%. Just press it once or when the body is close, the faucet will turn on, and it will automatically turn off after leaving, which is convenient and avoids cross-contamination. However, the disadvantage of the delay faucet is that it generally cannot adjust the amount of water arbitrarily and does not have a self-locking function. The delay time is also fixed, and the water is often stopped before the hands are cleaned. It is very inconvenient to use. Otherwise, the people leave and the faucet has not been turned off, resulting in a waste of water resources, and the scope of application is limited. sex. The principle of time-delay faucet-what is the principle of time-delay faucet The time-delay faucet is based on the principle of infrared reflection. When the human hand is placed in the infrared area of the faucet, the infrared light emitted by the infrared transmitting tube is reflected to the infrared receiving tube due to the blocking of the human hand, and the signal is processed by the microcomputer in the integrated circuit. For the pulse solenoid valve, the solenoid valve receives the signal and then opens the spool according to the specified instruction to control the water from the faucet; when the human hand leaves the infrared delay range, the solenoid valve does not receive the signal, and the solenoid valve spool is reset by the internal spring. Control the turning off of the faucet. AC and DC power supply, battery backup, water when hand is extended, water is stopped when hand is closed, especially water saving, water switch is automatically completed by the delay device, without touching the faucet, which can effectively avoid bacterial cross-infection, the machine is controlled by a microcomputer, according to the basin The shape determines the best delay distance, no manual adjustment is required. It also has a 1-minute overtime washing and water stop function to avoid waste of water resources due to foreign objects within the delay range for a long time. DC uses 4 AA alkaline batteries, which are used every day 1000 times, 2 years without battery replacement, built-in filter mechanism to prevent impurities from entering the electromagnetic valve, easy to clean, beautiful appearance, firm structure, suitable for crowded places. The principle of the delayed faucet is temporarily introduced here. One of the biggest effects of delayed faucets is to save water. When the delay faucet has obstructions, infrared rays can be felt. So the water can flow out from the tap in time. When the obstruction leaves the sight of the faucet, the delayed faucet will automatically shut down and the water can't flow out. So the delay faucet is very environmentally friendly.

At present, the valve cores of faucets sold on the market mainly have three common materials: ceramic, stainless steel, roller type, etc. The quality and advantages of faucet cartridges made of different materials are different: Ceramic valve core: Because of its affordable price, low water pollution, good wear resistance, good sealing performance, and the improvement of "brittleness", ceramic valve cores are widely used. In general, the ceramic valve core plays a very good sealing role. Due to the relatively strong foreign technical strength, some imported ceramic chips have relatively better sealing performance, stable physical properties, wear resistance and long service life. At present, most of the mainstream faucets produced by most well-known brand sanitary ware manufacturers on the market have adopted ceramic valve cores. Roller spool: Its advantages are smooth handle rotation, easy and simple operation, comfortable and easy hand feeling, aging resistance and abrasion resistance. However, as an old-fashioned cartridge, the roller cartridge has been gradually unable to meet the needs of the current population for the spool, so it will be gradually eliminated by the market. Roller cartridges are rarely seen in the leading brands produced by major brands. Stainless steel ball valve: It is currently a leading valve core with high technological content. Some high-end bathroom brands use irregular seven-hole steel ball valve cores processed by laser technology as the valve cores of their latest faucet products. Industry insiders also believe that this valve core is more suitable for areas with poor water quality, because it is not affected by impurities in the water and will not shorten its service life. Moreover, the handle of the steel ball valve core has a larger angle in the area where the water temperature is adjusted, which can accurately control the water temperature, ensure that the hot water flows out quickly and accurately, and save 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 manufacturing process requirements are more refined, which is suitable for applications in places with poor water quality. Precautions for purchasing faucet cartridges When choosing a faucet cartridge, no matter which type of cartridge you choose, if you want to choose high-quality products, you must pay more attention to the purchase process: 1. When purchasing, you can switch the faucet handle repeatedly, and use your hands to feel whether there is any resistance in the middle of the switch. Under normal circumstances, it is better to not feel obstructed. 2. When the spool is left and right, it can be judged by feeling. When the cartridge is left and right, it is "idling", the hand feel is very light, and there is no resistance. 3. Use the index finger and middle finger to gently clamp the handle of the faucet and move it up and down, left and right, and obs...

The angle valve is an angle stop valve. The angle valve is similar to the ball valve, and its structure and characteristics are modified from the ball valve. The difference with the ball valve is that the outlet of the angle valve is at a right angle of 90 degrees to the inlet。 1.Usage The angle valve has four main functions: 1. Transfer inside and outside water outlets 2. The water pressure is too high, you can adjust it on the triangle valve, turn it down a little 3. The function of the switch, if the faucet leaks, etc., the triangle valve can be turned off instead of the main valve in the house. 4. Decoration 2.Industrial usage The valve body of the angle valve has three ports: water inlet, water volume control port, and water outlet, so it is called triangle valve.

Check the plating quality The quality of the electroplating layer of the shower head determines its appearance and longevity.Shower with good quality has multi-layer electroplating, the outer surface is flat and smooth, and the lines are beautiful, also it will not rust after many years of use. Showers with poor quality are dull in appearance, and some may be brighter, but the electroplating layer is thinner then the good one, and corrosion will appear after a period of use, which affects the appearance, and the rust is not good for our healthy. When choosing a shower, it is best to check the authoritative test report if it passed, so that the quality can be assured. Check the materials The main raw materials of shower heads are brass, alloys, etc. Of course, brass is the most good quality. However, the quality of brass are also different. The brass with high content has high hardness, less impurities, and is not easy to crack. Inferior brass has a relatively high content of other metals and many impurities, which may contain lead, it will do harmful to our body healthy. At present, there are several grades of brass, such as H38, H59, H62, etc. H62 copper has the best quality, strong corrosion resistance, strong and durable quality; H38 is the most poor quality, which contains less copper and more easier corroded, and the durable is low. When buying a shower, you can ask which grade of brass material it has. Shower spout The quality of the shower nozzle is also related to its service life. High-quality shower spouts always use high-quality silica gel as raw materials, which are environmentally friendly and healthy, not easy to block, and also more easier to clean. For poor-quality showers, the spout is made of ordinary plastic. The material is relatively hard, and it is easy to form scale, clogging the water outlet, the water is not smooth, and it is hard to clean. It will has an impact on health. Pay attention to the cartridge The cartridge is the heart of the faucet, it is very important. High-quality showers generally use high-strength ceramic valve cores, which have good sealing performance, high wear resistance, and are not easy to leak. Poor quality showers have poor valve core quality, which is prone to aging and wear, poor sealing, and with short service life. After a period of use time, water leakage or the faucet may looseness. When purchasing a shower, you should check and open the faucet and look at the valve core inside, or ask about the certificate of quality appraisal. Shower pipe The shower pipe is the most important part of the shower sets.It should also be paid attention to when choosing. The thicker the wall of the shower pipe has then the better quality and the more durable it is. The general thickness about 0.6~1.0 mm, and the diameter of the shower pipe is about 20-25 mm. In addition, the inner and outer walls of the shower pipe must be smooth, the workmanship need to be meticulous, and also corrosion-resistant, so that the ...

Faucets, angle valves, showers, this kind of household water-related hardware, always claim to be all copper. But is all copper really good? This is not necessarily true. At least copper can never avoid rust in use! In order to prevent rust, copper will make some improvements in the material-made of copper-zinc alloy or copper-lead alloy (so all copper ≠ pure copper). If so, its corrosion resistance is still difficult to meet the demand. So we have to make some articles on the surface-electroplating process. The so-called "copper" faucets and other hardware we usually see are all copper that has been alloyed and electroplated. Better than copper is stainless steel. This thing is quite resistant to corrosion, "not rusting" is just its basic ability. And the hardness is high, relatively speaking, the life span is longer. The reason why it is difficult to see stainless steel in water fittings is mainly because its hardness is too high-when processing high-precision products such as faucets, high hardness means high difficulty. Therefore, stainless steel hardware is not absent, but the price is too high and the cost performance is too low. Overall, copper hardware is not the best, but it is the most cost-effective. For home users, copper hardware has been able to meet the demand.
