How faucet works?

According to the usage: faucets are roughly divided into the following three types: kitchen faucets, bathroom faucets, bathtub faucets.

Though there are hundreds of different styles, colors, and shapes of faucets, the working mechanisms of nearly all can be grouped into four main types: cartridge, compression, ball, and disc. These names refer to the parts that actually control the flow of water through a faucet.

The type of valve you choose will make a difference in a faucet’s price, how well it works and how long it will last.

According to the structure, faucets can be divided into single connection, double connection and triple connection. In addition, there are single handle and double handle. The single connection type can be connected with cold water pipe or hot water pipe; the double connection type can be connected with two cold and hot pipes at the same time, which is mostly used for the faucet of bathroom basin and kitchen dish basin with hot water supply; the triple connection type can be connected with shower nozzle in addition to two pipes of cold and hot water, which is mainly used for the faucet of bathtub.

  1. Faucet cartridge

Faucet cartridge is the lifeblood of the faucet, which largely determines the quality and service life of the faucet. The faucet cartridge mainly includes ceramic valve core, ball valve core, stainless steel valve core and rubber valve core. Among them, ceramic valve core is the best at present, with good performance and stable physical property. Generally, the faucet with ceramic valve core can be used for 5-10 years.

Working principle of ceramic valve core:

Generally, the bottom of ceramic valve core is composed of three holes, one of which is used for cold water inlet and outlet. The other for hot water inlet and outlet, and the remaining one for outlet water from the valve core.

The cold and hot holes of the valve core of the faucet are provided with sealing rings to ensure that the inclined street of the faucet is in a sealed state. After the main body of the cold and hot water inlet pipe is connected, the hot water pipe and the cold water pipe pipe are one-to-one corresponding to the two holes of the valve core. The valve core mainly controls the opening and closing state of the two holes and works by moving the ceramic plate.


2.Faucet body

The main body of the faucet refers to the pipe body, which was mainly made of bronze. But now it has been replaced by brass. The copper content of high-grade faucet is more than 85%.

The cartridge is the entire basis for the faucet's function. It contains a rocker switch capable of blocking off or opening both hot and cold water lines entirely, as well as to varying degrees. In other words, when you raise the lever to turn the water on, you're pushing the cartridge forward, causing both water lines to unblock.

When you push the lever down, both water lines are blocked entirely, turning off the water flow. This is the simple part. The genius of this device is that, based on how far the lever is pressed to one side or the other, the hot and cold water lines are opened at different ratios.

When centered, the cartridge lets water from both lines pass equally. When pressed to the left, the cartridge lets more water from the hot line pass than the cold line until the cold line is blocked entirely. Similarly, when pressed to the right, the cartridge lets more water from the cold line pass than the hot line until the hot line is blocked entirely.

3.Internal structure of faucet

The internal structure of the hot and cold faucet is mainly composed of connecting gooseneck, flushing pipe, sealing ring, bottom root box and connecting central pipe. The valve core of cold and hot faucet has cold and hot holes, and the sealing ring ensures the sealing performance. The valve core mainly controls the opening and closing state of the two holes, and the ceramic plate on the valve core controls its main work.

4.Structure and principle of kitchenbasin faucet:

The screw valve core is mainly composed of a rotary valve core and a valve stem displacement, which is mainly achieved by opening and closing the valve stem.

When we rotate the valve stem, the thread is engaged to make the sealing end of the valve core move forward and backward. When we twist the valve core in, we seal the water inlet and seal the position of the water outlet. The alternation of cold and hot water is realized by sealing the sealing end of the valve core to the water outlet.

The working principle of the screw valve core of the faucet is to realize the opening and closing of the water hole by shifting the T thread through the rotation of the valve stem. When we rotate the stem, the threads engage. When the valve core is in or backward, the valve core is closed.

5.Structure and principle of bathtub faucet:

General bathtub faucet is through s shift to make water into the main body, but first also into the spool, from the spool into the main body. The water enters the hole on the left side of the commutator in the main body to realize the opening and closing of the water flow through the lifting position of the commutator.

6.The working principle of the commutator inside the faucet is as follows:

The commutator realizes the function of the channel switching between the aerator and the shower through the sealing ring and the main body. Note that we see in the commutator, the line to be symmetrical and asymmetric. There will be water leakage.

Through the introduction above, I believe we all know that different types of faucets have different structures and principles. Therefore, when purchasing faucets, you should also look at your actual needs. For example, when using bathrooms, you should buy special faucets in bathrooms online, so that they can be more convenient to use.
