The main hot and cold water faucet consists of a handle, a valve core, a water inlet braided tube and mounting gadgets. The working principle of the ceramic valve core: In general, the bottom of the ceramic valve core consists of three holes, one of which is used for entering and leaving cold water, the other is for entering and leaving hot water, and the other one is used for water supply inside the spool. The faucet valve core has cold and hot two holes with sealing ring to ensure that it is sealed with the main body oblique street. After connecting the main body of the cold and hot water pipe, ensure that the hot water pipe and the cold water pipe are in one-to-one correspondence with the two holes of the valve core. The spool mainly controls the opening and closing of the two holes and relies on the movement of two ceramic sheets.
The handle switch drives the valve stem to move, so that the ceramic piece moves, and the left and right holes are sealed, and the valve core is not watered at this time. The step seal of the spool allows the water flow to pass through the spool to enter the main body outlet passage so that no water enters the spool and no water flows out of the conduit. This is the closed state of the water pipe, the structure of the faucet and the working principle.
