How to install hot and cold faucets? Talking about the working principle of hot and cold water faucets

The hot and Cold Water Faucet can realize the switch of cold and hot water at the same time so as to meet the different requirements of the user for cold water and hot water, and can also be called a mixed water tap.

Hot and cold faucet principle

The principle is mainly used in the internal use of high-precision ceramic ceramic faucet or steel valve spool to control the water situation, so when using the faucet, it will appear in different directions in the direction of cold water and hot water.

Hot and cold water faucets are composed of handles, valve cores, water inlet braided hoses and mounting accessories. The working principle of the ceramic valve core: under normal circumstances, the bottom of the ceramic valve core consists of three holes, one of which is used to enter and exit the cold water, the other is used to enter and exit the hot water, and the remaining one is used to discharge the water inside the valve core. The cold and hot holes of the faucet valve core have seal rings to ensure that the oblique street of the main body is in a sealed state. After the cold and hot water inlet pipes are connected, the hot water pipe and the cold water pipe line correspond to the two holes of the valve core. The spool mainly controls the opening and closing state of the two holes and works by moving the two ceramic plates. The handle switch drives the valve stem to move, so that the ceramic sheet moves, and the left and right holes are sealed. At this time, no water enters the valve core. The sealing ring of the valve core allows the water flow to pass through the valve core so as to enter the main water outlet channel, so that no water enters the valve core, then no water flows out of the pipeline. This is the closed state of the water pipe, the structure and working principle of the faucet.

Common types of hot and cold faucet installation

At present, hot and cold water taps can be divided into Basin Faucets, vegetable basin faucets, and bathtub faucets according to different use places.

Basin faucet: Installed on the wash basin for hot water, cold water and cold water. Its shape can be changed, can be used for washing the face, laundry, general basin faucet to choose a relatively high leader, this can leave room for washing.

Single hole basin faucet installation

When buying single-handle basin faucet, you should pay attention to the outlet diameter. Most of the current market is hard pipe water, pay attention to reserve the height of the pipe, from the basin down to about 30 inside the best. When installing, it must be equipped with a special Angle Valve. The angle valve must be fixed with the hot and cold water pipes of the wall outlet. If there is a distance between the angle valve and the faucet hose, it is necessary to purchase a dedicated pipe to lengthen the link. Do not use other water pipes to connect, otherwise it will leak and fall off due to high water pressure. If the inlet pipe is too long to go beyond the outlet pipe, cut it off.

Vegetable basin faucets: Faucet are generally used for dishwashing. They are required to reach a certain height in order to facilitate dishwashing.

Bathtub faucets: Bathtub faucets have a relatively high requirement and are generally used as a control body and a shower head. They are required to be superior in material and performance to other faucets.

Bathtub faucet installation

If you buy showers, bathtubs, wall hangings, you need to choose a suitable height to bury the water pipe. Hot and cold water pipes are about 20 or more inside. Rinse the water pipe before installation to avoid damaging the water tap due to hard water.

Concealed shower, bath faucet: After purchasing a concealed faucet, it is generally necessary to embed the valve plug of the faucet in the wall. The thickness of the bathroom wall should be taken into account before being embedded. If the wall is too thin, the valve plug cannot be embedded. The plastic protection cover of the valve plug should not be easily removed when it is embedded, so as to prevent the cement and other chores from damaging the valve plug when it is embedded. In addition, when embedding the valve core, it should also pay attention to the direction of the valve core up and down, left and right, so as not to miss the valve core.
