    How to install the angle valve

    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.

    How to choose a kitchen sink and faucet?

    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...

  • What are the identification methods of stainless steel 304 faucet and its maintenance methods.
    Dec 13, 2021

    What are the identification methods of stainless steel 304 faucet and its maintenance methods.

    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.

    What is the Induction Sensor Faucet?

    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...

    What is Angle Value?

    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...

    Introduction the Principles of Time-delay Faucets

    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.

    How to choose faucet cartridges

    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...
