We are familiar with the faucet. As the most frequently used household tool every day, relatively no matter the price of the faucet, the use of a long time, there are many problems with the faucet, such as faucet dripping, faucet leaking, faucet plugging, etc., which requires us Learn the structure and principle of the faucet. Below, let's take a look at the structure and principle of the faucet!
Taps can be divided into single, double and triple taps by structure. In addition, there is a single handle and dual handle points. Single connection type can be connected to cold water pipe or hot water pipe; double type can connect cold and hot pipes at the same time, and it is mostly used for bathroom basins and kitchen sinks that need hot water supply; triple connection removes cold water and hot water from two pipes , You can also connect shower heads, mainly used for bathtub faucets.
Tap main parts
1, tap valve
The faucet valve core is the lifeline of the faucet and largely determines the quality and service life of the faucet. Faucet spools include ceramic spools, ball spools, stainless steel spools, and rubber spools. The ceramic valve core is currently the best, sealing performance, and physical stability. General ceramic valve faucets can be used for 5-10 years.
2. Faucet body
The main body of the faucet is the body of the pipe, mainly made of bronze material, but now it has been replaced with brass. The content of high-grade faucet copper is above 85%. There is no air hole in the main body of the imported faucet. However, due to the limitations of the price and the surface tumbling treatment, the domestic faucet lacks the pressure resistance, abrasion resistance, and corrosion resistance that are unique to imported faucets.
3, the internal structure of the faucet
The internal structure of the hot and cold faucet is mainly composed of connecting a gooseneck, a punching tube, a sealing ring, a lower packing box, and a connecting center tube; the cold and hot water tap valve core has two holes of cold and hot, and a sealing ring ensures the sealing performance. The spool mainly controls the opening and closing state of the two holes, and the main work is controlled by the ceramic sheet on the spool.
We often use faucets mainly kitchen basin faucets and bathroom bathtub faucets. Here we come to understand the structure and principle of the two faucets.
Bathtub principle
In general, a bathtub faucet is used to make water enter the main body through S-shift, but first, it also needs to enter the spool and flow from the spool into the main body. Water enters the hole in the left side of the commutator in the main body, and the switching action of the water flow is achieved by lifting the commutator. The commutator achieves the function of switching the bubbler and shower channel inside the main body through the seal ring and the main body. Note that the commutators we see are symmetrical about the centerline, and if they are asymmetric, they will leak.
Kitchen faucet principle
The kitchen faucet is mainly composed of a spiral valve core, which mainly relies on the rotation of the valve stem and is displaced by the thread to achieve the effect of the water inlet hole switch. When we rotate the stem, the thread engages to advance and retreat the sealed end of the spool. When we twist the valve core, we seal the inlet and seal the position of the outlet. We rely on the sealed end of the valve core to seal the outlet to achieve the alternating cold and hot water.
