The structure and principle of faucet control water

Faucet is a common object in life, it greatly facilitates our lives and saves water. How to choose a good faucet when we buy a faucet? In addition to choosing the brand of the faucet, we can also understand its structure and see how it is completed.

Compared with the faucet of the past, the current faucet is more messy and changeable. Therefore, if we want to understand the structure diagram and principle of the faucet, we must grasp and understand the structure diagram of the faucet. The faucet structure diagram shows us the various parts of the faucet, so that we can understand it better, otherwise we don't even know what is inside the faucet.

We can see that the structural drawing of the basin is still very messy. It is a single-handle ceramic valve core surface, which is mainly composed of a handle, a valve core, a water inlet woven pipe and small fittings. It also includes some sealing rings, screws and so on.

The working principle of ceramic valve core:

Under normal circumstances, the bottom of the ceramic valve core consists of three holes, among which two holes are used for cold water in and out, the other is used for hot water in and out, and the remaining one is used for water out of the valve core.

The faucet valve core has sealing rings for the cold and hot holes to ensure that it is in a sealed condition with the main slanted street. After the cold and hot water inlet pipe main body is connected, ensure that the hot water pipe and the cold water pipe correspond to the two holes of the valve core one by one. The spool mainly controls the opening and closing of the two holes and relies on the movement of the ceramic piece to work. Where the water quality is not good, it can pass through the device filter to filter impurities, and at the same time prevent the impurities from harming the ceramic valve core. There are two installation positions for the filter: the water inlet and the water outlet.

Because there are many types and classifications of faucets, the planning of different classifications of faucets is very different, so the faucet structure diagram is different. Therefore, we must first recognize the types of faucets. Generally, the faucets we use in our daily life are: the difference between single-type faucet, double-type faucet, and triple-type faucet, and according to the different handles, it can also be divided into single handle And double handle faucet. These different faucets are very different in the faucet structure diagrams, so we must first classify them and then understand the related faucet structure diagrams. Let's take a bathtub faucet as an example for a brief explanation.

Bathtub faucet

The bathtub faucet uses the S shift to allow water to enter, but it still has to enter the valve core first, and then flow into the main body from the valve core. Water enters the water hole on the left side of the commutator and passes through the commutator to achieve the effect of opening and closing the water flow. The commutator completes the function of switching between the bubbler and the shower channel inside the main body through the cooperation of the sealing ring and the main body. Note that in the commutator we have seen, the center line should be symmetrical. If it is asymmetrical, water leakage will occur.
