Working principle of common household faucet

The faucet is mainly composed of a spiral valve core, which mainly depends on the rotation of the valve stem and the displacement of the thread to achieve the effect of opening and closing the inlet hole. When the valve stem rotates, the threads mesh to make the sealing end of the valve core move back and forth;

When the valve core is screwed in, the water inlet is sealed, and the position of the water outlet is also sealed, and the water outlet is sealed through the sealing end of the valve core, thus realizing the alternation of cold water and hot water.

Mainly through the rotation of the valve stem, the T-shaped thread is displaced to realize the opening and closing of the water hole. When we turn the valve stem, the threads engage. When the sealing end of the valve core enters or retreats, it will realize the function of closing, while retreating is the function of draining water.

Pay attention to when purchasing faucets:

1, weight: you can't buy a faucet that is too light. Too light is mainly because the manufacturer hollowed out the copper in order to reduce the cost. The faucet looks big, it is not heavy to carry, and it is easier to withstand water pressure bursting.

2. Handle: The composite faucet is easy to use, because when using the sink, usually only one hand is empty.

3. Water outlet: The high water outlet is convenient for basin irrigation.

4. Valve core: This is the heart of the faucet. Hot and cold faucets are all ceramic valve cores, and the best quality valve cores are Spanish Circuit, Taiwan Province Kangqin, Zhuhai and other names.
