The Structure Of The Basin Faucet
Apr 14, 2025
The core structure of the basin faucet can be divided into the following main parts:
Valve core (control core)
As the "heart" of the faucet, it is responsible for adjusting the water flow switch and temperature control. At present, the mainstream adopts ceramic valve core, and its principle is to change the mixing ratio of hot and cold water by the displacement of ceramic pieces. High-quality ceramic valve core has the characteristics of strong wear resistance and good sealing, which directly affects the service life (it is recommended to use products with a life of 500,000 switch tests).
Water outlet system
Nozzle: The key component that determines the shape of water flow. Modern designs often include: Aerator: The water flow is formed into bubbles through a multi-layer honeycomb filter to reduce splashing and improve water saving effect Pull-out/lifting structure: High-end models are equipped with retractable water outlets for multi-angle use Bend structure: Some models adopt a rotatable bend design for multi-area water extraction Control components Single/double handle: The single handle controls the switch and temperature by moving up and down/left and right, and the double handle controls hot and cold water independently Pull-out/press mechanism: Used to control water in special styles The device opens and closes, which is common in basins with overflow holes
Main structure
Casting body: generally made of brass or stainless steel, with integrated hot and cold water channels
Installation interface:
Single hole/double hole installation: The international standard hole spacing is 4 inches (about 10cm), corresponding to different countertop opening requirements
Concealed embedded parts: Wall installation requires pre-embedded valve core components to achieve a design without countertop openings
Connection system
Braided hose: The key component connecting the angle valve and the faucet. It is recommended to use 304 stainless steel explosion-proof pipes
Sealing components: Including rubber gaskets, thread sealants, etc. to prevent interface leakage
