Faucet is one of the commonly used kitchen and bathroom equipment in our daily life, especially hot and cold faucets can be very convenient for our home life. However, in the process of using the faucet, we sometimes encounter problems such as water leakage, which requires us to have a good understanding of the structure and principle of the faucet. Today, Bian Xiao takes you to know the structure diagram and principle of the faucet, which has a good guiding role for us to choose the faucet and troubleshoot the faucet.
Faucet is the common name of faucet, which is used to control the switch of water flow and has the function of saving water. The replacement of faucets is very fast, from the old cast iron process to the electroplating knob type, and then to the single temperature and single control of stainless steel. Now many families use stainless steel double-temperature and double-control faucets, and there are also kitchen combination faucets.
Faucet structure diagram
According to the structure, faucets can be divided into single connection, double connection and triple connection. In addition, there are single handles and double handles. Single connection can be connected with cold water pipe or hot water pipe; Double-type hot and cold pipes can be connected at the same time, which is mostly used for faucets in toilet basins and kitchen vegetable basins with hot water supply; In addition to connecting hot and cold water pipes, the triple type can also be connected with a shower nozzle, which is mainly used for the faucet of a bathtub.
Main parts of faucet
Knowing the structural classification of the faucet, let's take a look at the main components that make up the faucet structure.
1, faucet spool
The faucet valve core is the lifeblood of the faucet, which largely determines the quality and service life of the faucet. Faucet spool mainly includes ceramic spool, ball valve spool, stainless steel spool and rubber spool. Among them, ceramic valve core is the best at present, with good performance and good physical stability. Generally, the faucet with ceramic valve core can be used for 5- 10 years.
2. Faucet body
The faucet body refers to the tube body, mainly made of bronze, which has been replaced by brass, and the copper content of high-grade faucet is above 85%. The main body of imported faucets basically has no air holes, while domestic faucets lack the unique compressive, wear-resistant and corrosion-resistant properties of imported Huasheng theory due to the backwardness of price and technology and the limitation of surface sand-turning treatment.
3. Internal structure of faucet
The internal structure of hot and cold faucet is mainly composed of connecting gooseneck, flushing pipe, sealing ring, lower packing box and connecting center pipe; The valve core of hot and cold faucet has two holes, cold and hot, and there is a sealing ring to ensure sealing performance. The valve core mainly controls the opening and closing state of the two holes, and the ceramic sheet on it controls its main work.
The faucets we often use mainly include kitchen vegetable basin faucets and bathroom bathtub faucets. Let's take a look at the structure and principle of these two faucets.
Principle of bathtub faucet
Bathtub faucet generally lets water enter the main body through S displacement, but it must first enter the valve core and flow into the main body from the valve core. Water enters from the hole on the left side of the commutator in the main body, and the water flow can be turned on and off by lifting the commutator.
The working principle of the commutator in the faucet is that the commutator cooperates with the main body through the sealing ring to realize the switching function between the bubbler and the shower channel in the main body. Note that in the commutator we see, the center line should be symmetrical, otherwise it will leak water.
Principle of kitchen faucet
The faucet in the kitchen is mainly composed of a spiral valve core, which mainly depends on the rotation of the valve stem and the displacement of the thread to achieve the effect of opening and closing the inlet hole.
When we rotate the valve stem, the threads bite, so the sealing end of the valve core moves back and forth. When we screw in the valve core, the water inlet is sealed, and the position of the water outlet is also sealed, so that the alternation of cold water and hot water can be realized by sealing the water outlet through the sealing end of the valve core.
The working principle of the spiral valve core of the faucet is that the T-shaped thread is displaced by the rotation of the valve stem to realize the opening and closing of the water hole. When we turn the valve stem, the threads engage. When the sealing end of the valve core enters or retreats, it will realize the function of closing, while retreating is the function of draining water.
What should I do if the hot and cold faucet leaks?
1. If the hot and cold taps are controlled by the main water inlet valve, close the main valve. When the cold and hot water inlet pipes are separated, close the corresponding two valves.
2. Open the accessory "0 1 cold and hot label" shown in the above figure with a flat screwdriver;
3. Put a flat screwdriver into the hole plug of the handle fixing screw, and turn the screwdriver counterclockwise for about 3 turns;
4. Grasp the faucet handle with your left hand, push it upward, and tap it gently with the handle at the back end of the screwdriver, so that the accessory "02 water outlet handle"? Be separated;
5. Assemble "03 end cover" counterclockwise, and the end cover is separated from the main body;
6. Place the starting end of adjustable wrench at the hexagonal position of the pipe fitting "04 Hexagon sleeve for valve core fixing", adjust the size of the starting end of adjustable wrench, rotate it counterclockwise, remove the ceramic valve core for inspection, and tighten it clockwise if it is intact. Stop trying; If it is damaged, replace it with a new valve core.
7. Replace the fittings "03 end cover", "02 outlet handle" and "0 1 cold and hot standard" as they are.
The above is the relevant content of the faucet structure diagram, I hope to help everyone!
Introduction of structure and principle of super-full faucet
Faucet is one of the necessities in daily life. Many people only pay attention to the brand when buying, and don't understand that the structural principle of different faucets is different. Different structural principles and designs of faucets are doomed to different application scopes, so if you want to choose a suitable faucet in your daily life, you may wish to read this article.
Structure principle of faucet in washstand
Compared with the common faucet structure, the faucet structure on the washstand will be more complicated. The faucet of the washstand is mainly composed of valve core, braided water inlet pipe, handle and some small accessories. There are mainly three holes in the interior, which are used for cold water, hot water and internal water outlet. This structural design brings great convenience to people's daily life, and at the same time, the life of the faucet designed in this way will be longer, and different water will flow out when the handle is turned in different directions.
Structure principle of vegetable basin faucet
The faucet design in the kitchen is obviously different from that on the washstand. Kitchen faucets are basically composed of a spiral valve core, mainly through the displacement of spiral threads, and then the water flow can be controlled. Even the control and alternation of hot water and cold water is influenced by the valve core, which has a water outlet and a sealed water inlet respectively. Only by adjusting the direction of the thread on the screw can the control of cold water and hot water be realized, and it will be more convenient to wash vegetables.
Structure principle of bathroom faucet
Compared with the above two kinds, the faucet in the bathroom is more complicated. First, water will pass through the valve core, and water will mainly enter the main body through the valve core. After entering the main body, there will be a shunt and a commutator, which will pass through the commutator and enter the hole on the left. The main function of commutator is to control the switch of water flow, but it is difficult for many friends to distinguish the specific position and flow direction of water purification faucet in real life.
these are
What is the structure of the faucet?
The internal structure of faucet plug body includes plug body, control cover body, control valve rod, two silencing plates, fixed plate, balance rod, balance diaphragm, compression nut, two C-shaped retaining rings, two silencing blocks and two balancer housings. In this structure, the middle section of the balance bar near the cold water guide post is provided with a threaded flange, which can be locked and fixed by a compression nut to effectively compress and clamp the balance diaphragm, so the water inlet pressure is extremely high. In this structure, the silencing blocks are respectively installed in the two-stage grooves at both ends of the balance rod, and the spoiler column and silencing sheet are installed in the mixing chamber at the inner end of the control valve rod, which can effectively reduce the noise of water flow.
Description of faucet structure
Now there are many kinds of faucets, including cold water faucets, basin faucets, bathtub faucets and shower faucets. However, according to the structure of faucets, they are all similar and can be divided into one-way, two-way and three-way. What is their internal structure? I'll introduce it to you today so that you can buy it later.
The faucet mainly includes the following parts: valve core, handle, filter tip, water outlet, installation component, etc. Some faucets also have check valves, bubblers, fixing bolts, fixing copper sheets, washers, bent feet, hoses and so on. , and the components will vary from faucet to faucet. The valve core is the core component, which controls water flow switch, flow rate and mixing ratio of hot and cold water. The quality of the valve core determines the functional reliability and service life of the faucet, which is also very important in the faucet structure. When consumers buy faucets, they must choose good quality valve cores.
Small faucets may not attract people's attention, but they are also indispensable in life. The structure of the faucet directly affects the amount of water charges at home. When purchasing a faucet, we should not only look at the quality of the faucet core, the material of the faucet and the surface electroplating, but also look at its adaptability to water quality and water saving. A good faucet has a smooth appearance, water saving and durability. When pulling the switch, if it feels soft and effortless, it means that the faucet is more accurate.
Sheng Di Sanitary Ware has been deeply loved by consumers in faucet. With copper as the main material and electroplated layer, it has stronger oxidation resistance and corrosion resistance than other brands, which is conducive to prolonging the life of faucet. I believe that after you buy it, you will save water and feel the excellent service in Sheng Di.
Structure diagram and principle of faucet
The faucet consists of a main body, a valve core, a handle and a water filter nozzle.
Working principle:
At the outlet of the faucet, the pipe flow of water becomes a linear flow, and then the linear flow is turned into a jet by the pressure of air. After the air is pressurized, the water has power, which reduces the flow of water and increases the pressure of water flow.
It can easily replace the ordinary filtering device in the outlet nozzle of the original faucet, and can match the faucet with international standard size. Correctly installed water saver will make users realize the great difference before and after use in a short time: lower water fee, lower energy consumption and higher outlet pressure.
This kind of water saver reduces the original multi-layer steel wire filter screen, which can effectively prevent the accumulation of dirt and put an end to the possibility of bacterial growth. Equipped with a patented wrench, it is convenient to disassemble and clean, saving water and energy while effectively protecting human health.
When in use, the valve core enters the water outlet, and the water outlet pipe is in a semi-closed state. Therefore, if the control of valve 1 remains unchanged, the water flow will be blocked at valve 2, and the water flow will become smaller and the water impulse will become larger.
Features: Make energy-saving and efficient faucets in a simple and acceptable way for consumers.
Description: A valve is connected in series at the outlet of the faucet. If it is necessary to increase the impulse of water flow, the valve can be controlled. By adjusting the size of the water outlet, the flow and impulse of water can be adjusted.
Time-limited infrared water-saving faucet has the following characteristics: first, the human body is induced to turn on, and the person automatically turns off when he leaves; Second, if the hand sanitizer hasn't left after the time limit, the faucet will automatically turn off, thus saving water.
Working principle: The device is mainly composed of infrared detection, time-limited control, execution and power supply. After C 1 step-down, VD 1 rectification, DW voltage stabilization and C2 filtering, the 6V voltage supply circuit is obtained. Infrared detection is completed by IC 1 IC 1 is a subminiature pyroelectric integrated infrared sensor AMN 1 recently introduced by Matsushita Corporation of Japan. The to-5 metal shell is used for packaging, which has strong anti-interference ability and the static working current is only170μ a. ..
When the human body approaches IC 1, its output terminal outputs a high level, so that BG 1 and BG2 are successively saturated and turned on, and the time-base integrated circuit IC2 connected as a timer is powered on, and the power supply charges the capacitor C4 through R5. First of all, the low potential at the positive terminal of C4 can't suddenly change, the pin 3 of IC2 outputs a high level, the light-emitting diode in the silicon-controlled photoelectric coupler IC3 emits light, the built-in silicon-controlled rectifier is turned on, the power silicon-controlled rectifier SCR is turned on, and the solenoid valve DF- 1 is energized to turn on the faucet. When a person leaves IC 1, IC 1 outputs a low level because it can't detect the infrared rays emitted by the human body. BG 1 and BG2 are turned off one after another, IC2 is powered off, IC3 and SCR are also turned off one after another, and the faucet is turned off.
When the tap is turned on, with the continuous charging of C4, the potential of pin 2 and pin 6 of IC2 gradually rises. If the user of the faucet does not leave, when the potential of pin 2 and pin 6 of IC2 rises to 2/3 VDC, the pin 3 becomes low, IC3 and SCR turn off, and DF- 1 forcibly turns off the faucet, thus ensuring water saving. Once a person leaves the faucet, the charge on C4 will immediately discharge through the interior of IC2 and VD2 and R8, and the successor will repeat the above process when using the faucet.
Installation and manufacturing: all components can be soldered on a small circuit board and placed in the wall switch box next to the faucet. Drill a hole with a suitable size on the switch board, so that the sensor lens can receive infrared rays emitted by the human body. Because the horizontal detection angle and vertical detection angle of the sensor can reach100 and 82 respectively, and the maximum detection distance is 5 meters, in order to avoid misoperation, it is necessary to set a baffle at a proper position in front of the lens so that it can only receive infrared radiation signals from people close to the faucet.
After the production is completed, it is only necessary to properly adjust the resistance value of resistor R5, so that the limited time becomes a normal one-time hand washing time. The rest need not be debugged.
