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. If you have interest in hot water faucets please kindly contact with D&S Faucets Company,we will provide the best quality and good service for you.

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...

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.

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...
