The cold and hot faucet can switch between cold and hot water to meet the different needs of users for cold and hot water Together, it can be called a mixed water faucet

Principle of cold and hot faucets

The principle is mainly to use high precision ceramic discs or steel valve cores inside the faucet to control the water outlet condition, so that when using the faucet in different directions, there will be a distinction between cold water and hot water

The cold and hot faucet should be composed of a handle, valve core, inlet weaving pipe, and equipment accessories The working principle of the ceramic valve core: Generally, the bottom of the ceramic valve core is composed of three holes, with one hole for cold water inlet and outlet, the other for hot water inlet and outlet, And the retaining one for internal water outlet of the valve core The cold and hot holes of the faucet valve core have sealing rings to ensure that they are in a sealed state with the main enclosed street After connecting the cold and hot water inlet pipes to the main body, It is ensured that the hot and cold water pipes correspond to the two holes of the valve core one by one The valve core mainly controls the opening and closing status of the two holes, releasing on the movement of two ceramic plates for operation The handle switch drives the valve stem to move, causing the ceramic plate to move The left and right holes are sealed, and at this moment, No water enters the valve core The sealing ring of the valve core requires water flow to pass through the valve core in order to enter the main outlet channel, so that no water enters the valve core and no water flows out of the pipeline This is the closed condition of the water pipe, the structure and working principle of the faucet

Common types of cold and hot faucet equipment

Nowadays, hot and cold faucets can be divided into base faucets, vegetable base faucets, and bathtub faucets according to different usage locations

Basin faucet: The device is located on the basin and is used to drain hot water, cold water, and a mixture of cold and hot water It shape can be changed and used for washing face and cloths Generally, for base faucets, a higher faucet should be selected to leave space for washing

Equipment for single hole base faucet

When purchasing a handload base faucet, you should pay attention to the diameter of the water outlet Nowadays, most of the hard pipes in the market are used for water inlet Pay attention to the reserved height of the water pipe, and it is best to go down about 30 meters from the basin when using equipment, it is necessary to choose a dedicated angle valve, Which must be fixed to the cold and hot water pipes for wall outlet Assuming there is a distance between the angle valve and the water pipe on the faucet, it is necessary to purchase a dedicated pipe to extend the connection Do not use other water pipes to connect, otherwise it may leak or fall due to high water pressure Assuming that the inlet pipe is too long and exceeds the outlet pipe, Cut off the remaining parts without dividing them

Vegetable base faucet: Vegetable base faucet is generally used for washing vegetables and dishes, and it is required to reach a certain height to facilitate washing vegetables or dishes

Bathtub faucets: The requirements for bathtub faucets are relatively high, and they are generally used for controlling the main body and showerhead They are required to have higher raw materials and performance than other faucets

Equipment for bathtub faucets

Assuming you purchase a shower, bath tube, or wall mounted faucet, you need to choose a suitable height for burying the outlet pipe The distance between the hot and cold water pipes is approximately 20 miles or more Wash the water pipe before the equipment to avoid damaging the faucet due to the hard water quality

Concealed shower and bathtub faucet: After purchasing a Concealed faucet, the valve core of the faucet should generally be embedded in the wall Before embedding, the thickness of the bathroom wall should be considered If the wall is too thin, The valve core will not be embedded Do not easily remove the plastic protective cover of the valve core during embedding to avoid damage to the valve core caused by cement and other miscellaneous materials during embedding In addition, when embedding the valve core, attention should also be paid to the up, down, left, and right directions of the valve core to avoid incorrect embedding
