Introduction of faucet

The classification of faucet

1.According to the opening method, it can be divided into spiral type, wrench type, lift type, press type, touch type and induction type. When the spiral handle is opened, it needs to be rotated many times; the wrench handle generally only needs to be rotated 90 degrees; the lift handle only needs to be lifted up to discharge water; the induction faucet will automatically discharge water as long as the hand is put under the faucet. In addition, there is a faucet with delayed closing. After turning off the switch, the water will continue to flow for a few seconds before stopping, so that the dirt on the hands can be washed off when turning off the faucet. The induction faucet uses the infrared induction principle, and the driving power supply is divided into two types: AC A/C and DC D/C. AC is 220V/50Hz or A/C110V/60Hz, and DC is driven by 4 No. 5 batteries with a voltage of 6V.

2.According to the function, it can be divided into basin faucets, bathtub faucets, shower faucets, kitchen sink faucets, bidet faucets, flush valves, induction flush valves, outdoor faucets, etc. Generally speaking, the water outlet of basin faucets is lower and shorter, and the faucets used in the kitchen are generally long-mouthed and rotatable, installed between two washing basins. The distance between the two water inlet holes of the mixed water shower faucet is generally 15CM+/-1CM. Some shower faucets have a lower water outlet in addition to the top spray and hand-held shower, which is convenient for taking water outside the shower. The water outlet of the bidet faucet can be rotated 360 degrees.

3.According to the temperature of the water outlet, it can be divided into single cold faucet, hot and cold mixing faucet and thermostatic faucet. The thermostatic faucet is equipped with a thermistor at the outlet of the thermostatic valve core. The characteristics of the temperature sensing element are used to push the valve core of the valve body to move, block or open the water inlet of hot and cold water, so that the outlet water temperature is always kept constant. The thermostatic faucets on the market mostly use three methods: memory alloy, paraffin, and pressure-stabilizing valve to achieve the constant temperature effect. The water pressure of the thermostatic faucet has certain requirements, generally required to be 0.1-0.5Mp, and the pressure difference between cold and hot water cannot be too large. If the hot water pressure of the thermostatic faucet is less than 0.05, the thermostatic faucet is not suitable. The hot water temperature is generally required to be 49-80 degrees, and the temperature adjustment knob can be set arbitrarily between 35℃-65℃. The thermostatic faucet is set with a 38℃ safety button to prevent scalding.
