What is the principle of hot and cold water faucet?

In fact, hot and cold water faucets are also called "mixed faucets"

That is, a faucet that mixes cold and hot water and regulates the water temperature. The principle is mainly to use a very high-precision ceramic piece or a steel valve core inside the faucet to control the water outlet, so that when using the faucet, there will be cold water and hot water in different directions.

Faucet principle: It is mainly composed of handle, valve core, water inlet braided pipe and installation accessories. In general, the bottom of the ceramic spool is composed of three holes, two of which are used for inlet and outlet cold water, the other for inlet and outlet hot water, and the remaining one is used for the water outlet inside the spool. The cold and hot holes of the valve core of the faucet have sealing rings to ensure that the main inclined street is in a sealed state, and the hot and cold water inlet pipe pipe is connected to ensure that the hot water pipe and the cold water pipe pipe correspond to the two holes of the valve core one by one. The valve core mainly controls the opening and closing state of the two holes, which is activated to the outlet position of the handle, and the corresponding water will come out.

We take the leftmost hole as the hot water hole, the right hole as the cold hole, the handle switch drives the valve stem to move, the ceramic plate moves, and the left and right holes are sealed, at this time there is no water entering the valve core. The spool is sealed so that the water must pass through the spool to enter the main outlet channel, so that no water enters the spool, then there is no water flowing out of the pipe. This is the water pipe closed state, faucet structure and working principle.
