After the water valve is opened, the faucet is clearly closed, but the water is smashed out! And in addition to the faucet, other pipes are normal! No way, I had to close the water valve and began to study the number of water inlets and outlets.
After disassembling and discussing it, I found out that this thing inside the faucet is broken. It is called "temperature-controlled spool." I am also the first time to dismantle the faucet. Don't laugh at me. It is the “center” for controlling the inlet switch and the conversion of hot and cold water on the faucet.
The side of the "temperature control spool" is a kind of drop, this new one is that I spent 7.5 yuan on a treasure to buy one, looking at the quality is not bad. Thanks to the powerful treasure, the "photo recognition" function is really good. Be sure to measure the inner diameter of the faucet supervisor before buying. Don't buy the wrong size.
The bottom of the "temperature-controlled spool" is like this, the two symmetrical small cylinders on the top are fixed. Then, a total of three inlet holes, one hole on the upper side to open the water when the water is closed, the bottom two holes for the hot and cold water switch. The structure is quite simple and not messy. Then look down, the disassembly and assembly of the valve core is officially open~ a small plastic stopper (red and blue) with a hot and cold water mark under the handle of the faucet, take this off. There is a screw inside, loosen it with a screwdriver (the screw can be removed without being directly removed, and it is better when it is installed). After gently removing the handle of the faucet, the spool is presented! Unscrew the fixed coil and take out the bad spool. This is the internal base structure of the faucet after removing the spool, and it has a one-to-one correspondence with the bottom of the spool! Install a new spool, install the screws and handles in reverse order - test the faucet, everything is normal, perfect correction
