Working principle of hot and cold faucet
Its principle is mainly to use a very high-precision ceramic piece or steel valve core to control the water outlet inside the faucet, so that cold water and hot water can be divided into different directions when using the faucet.
Faucet principle: it is mainly composed of handle, valve core, water inlet braided tube and installation accessories. Generally, the bottom of ceramic valve core consists of three holes, two of which are used for cold water in and out, another for hot water in and out, and the remaining one is used for water outlet inside the valve core. Both the cold and hot holes of the faucet valve core are provided with sealing rings to ensure that they are in a sealed state with the chute of the main body. After the hot and cold water inlet pipes are connected with the main body, ensure that the hot water pipes and cold water pipes correspond to the two holes of the valve core one by one. The valve core mainly controls the opening and closing states of the two holes. When it is started to the outlet position of the handle, the corresponding water will come out.
We use the leftmost hole as the hot water outlet and the right hole as the cold water outlet. The handle switch drives the valve stem to move, and the ceramic piece moves, so that the left and right holes are sealed, and no water enters the valve core at this time. The sealing ring at the valve core makes the water flow into the main water outlet channel through the valve core, so that no water will enter the valve core and no water will flow out of the pipeline. This is the closed state of the water pipe, the structure and working principle of the faucet.
Cold and hot faucet structure
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.
How to distinguish between hot and cold faucets
Look at whether there are defects in appearance and workmanship, such as sand holes, bubbles and grinding marks, and whether there is a coating, so as to be rust-proof, shiny and beautiful. You can press the tap again. If the fingerprint disappears soon, it means that the coating is good, and vice versa.
Second, look at the material, mainly to understand what material is the valve core of the faucet. Valve cores are generally divided into ceramic and stainless steel materials. Ceramic valve core is the best, leak-proof, good sealing effect, no need for rubber to help leak-proof, and it feels very light and flexible. Stainless steel valve core needs rubber ring to help achieve the best sealing effect and prevent water leakage, but after a long time, stainless steel balls will wear the rubber ring badly, and the rubber ring is easy to age and may leak water after a long time. But the outside of the faucet should be made of stainless steel to prevent rust.

Before installation, everyone has prepared the tools that may be used, one that can be used: wrench, waterproof tape; In addition, check whether the matching parts of hot and cold faucets are complete. Common faucet parts are: hose, rubber washer, shower head, drain pipe, crutch, decorative cap, etc.
Installation method of bath hot and cold faucet:
Hot and cold taps are commonly used in bathing. When installing, check which side is cold water and which side is hot water. Generally, hot water is connected to the left and cold water is connected to the right. After alignment, wrap the joint several times with waterproof tape to avoid water leakage, then screw the faucet on the joint, tighten it with a wrench, turn on the switch, and check that the direction of cold and hot water is correct, the water flow is normal and there is no water leakage. In addition, the shower head should be moved and adjusted according to the height. At present, the vertical hand-held shower head is widely used, and its height is generally 2050-2200mm. Generally, the height of movable shower on ceiling is 2 100-2300mm.
How to disassemble the hot and cold faucet?
First, turn off the main switch. Find a pair of red and blue dots. When you open it with your hand, a small hole is exposed.
Second, observe the hole with a flashlight to see if a fixing screw inside is cross or straight, and loosen it with a corresponding screwdriver.
This screw of a few brands is square hole (such as Mohn), which is more troublesome. When there is no tool, use other detachable alternative tools, and be careful not to damage the screw mouth.
Third, when you loosen this screw, you can take off the handle.
Fourth, what you see at this time is a big copper nut. After removing the nut with adjustable wrench, you can remove the valve core of the faucet.
