The geographic span of our planet is large, and many regions have distinct four seasons and the temperature varies greatly. With the arrival of winter, washing vegetables, washing dishes and washing clothes in cold water is really cold, so many families will choose hot and cold faucets. What is a hot and cold faucet? What is the working principle of the hot and cold faucet? What are the classifications of hot and cold faucets?
What is a hot and cold faucet?
Hot and cold faucets, as the name implies, are cold water and hot water that can be discharged through the same faucet, and through different hot and cold faucets, adjust different water temperatures to meet the needs of different people and different environments for warm water.
What is the working principle of the hot and cold faucet?
Hot and cold faucets are generally divided into handles, spools and inlet braided tubes, as well as several parts for mounting gadgets.
Among them, the spool is the core part of the hot and cold faucet. Typically, there are three holes in the bottom of the ceramic spool. One is connected to the cold water inlet pipe, one is connected to the hot water inlet, and the other is the water outlet. The hot and cold hole of the faucet valve core has a sealing ring, and then the handle switch is used to drive the valve core rod to move, and the ceramic piece is moved to realize the opening and closing of the faucet and adjust the water temperature.
If both seals are closed, the spool will not enter the water. At this time, the hot and cold taps are closed and no water is discharged. If we twist the faucet to the effluent state, the cold water inlet is closed, the hot water enters the valve core, and the hot water flows out; otherwise, the cold water is discharged. Put the handle in the middle, the hot and cold water pipes are opened at the same time, each half of the water, the warm water is flowing out. By adjusting the switch left and right, the size of the hot and cold water inlet is different, and the different water temperatures can be adjusted. The above is the working principle of the hot and cold faucet.
What are the classifications of hot and cold faucets?
There are also many different types of hot and cold faucets. After sorting out the classification, it helps everyone to buy the products they want.
According to the material, the hot and cold faucets can be divided into stainless steel, brass, aluminum alloy, plastic, 등. These are all common. The kitchen faucet is mostly related to drinking water. From a health point of view,we also recommended to buy a hot and cold faucet made of brass.
According to the function, the hot and cold faucets can be divided into kitchen faucets, basin faucets, shower faucets, electric faucets, drinking water faucets, bathtub faucets and the like.
According to the structure, it is generally divided into a large handle hot and cold faucet and a double handle hot and cold faucet. The single handle is a switch to control the entry and exit of hot and cold water. The double handle has two switches, one to control the hot water and one to control the cold water. The two start at the same time to adjust the water temperature. In Europe and the United States, or some old-fashioned bathtubs use double handles, but we recommend a single handle, which is better.
In terms of the opening method, the screw type, the wrench type, the lift type, and the induction type.We feels that the screwing type is not very easy to use, the children are not easy to unscrew, or have foam on their hands, which is easy to slip.
According to the valve core classification, there are stainless steel valve core, ceramic valve core, rubber valve core. The ceramic valve core is currently used more.
After introducing the working principle and classification of the hot and cold water taps, everyone knows what is the hot and cold tap, and it is also convenient for everyone to buy and improve the quality of life.
For the hot and cold water faucet, the difference from the cold water faucet is that it will be more complicated to install. Let’s take a look at the installation of the hot and cold water faucet!
Single hole hot and cold basin faucet installation
To install a single-hole hot and cold water faucet, it is necessary to reserve the height of the water pipe. It is best to reserve 30cm from the basin first. And must be equipped with a special angle valve, the angle valve must be fixed with the hot and cold water pipe of the wall outlet. If there is a distance between the angle valve and the water pipe on the faucet, you need to purchase a special pipe to lengthen the connection. Do not use other water pipes to connect, otherwise it will leak and fall off due to large water pressure. If the inlet pipe is too long beyond the outlet pipe, cut off the excess.
Installation of shower and bathtub hot and cold water tap
To install such a hot and cold water tap, you need to choose a height of 20 cm or more to bury the water pipe. Pay special attention to flush the water pipe before installation to avoid the water quality and damage the faucet.
If the home is a concealed shower and bath faucet, the faucet spool is to be buried in the wall. If the wall at home is too thin, the installation conditions cannot be met. The plastic protective cover of the valve plug should not be easily removed when it is buried, so as to prevent the cement and other chores from damaging the valve core when it is buried. In addition, when embedded the valve core, you should also pay attention to the up and down and left and right directions of the valve core to avoid the valve core being buried.
Single hole kitchen faucet installation
The installation of this type of hot and cold water faucet should pay special attention to the need for stability, so be sure to lock the nut. Choosing a good screw to stabilize the nut is the most important thing to pay attention to.
Hoof hot and cold water faucet installation
The first step: the hot and cold water pipes are respectively corresponding to the water inlets of the hot and cold water taps. This is not to be wrong.
Step 2: After the connection is completed, insert the fixed column of the faucet into the two inlet pipes to ensure the correct heat and cold.
Step 3: Install the assembled hot and cold water faucet on an object such as a sink or a washbasin, and put an inlet pipe in an opening such as a washbasin. Finally, the horseshoe pieces of the faucet are fixed and the screw nut is tightened.
