Building Materials Classroom: Classification and Selection of Bathroom Faucets

The classification of faucets is as follows:

According to the function of points, can be divided into basin faucet, bathtub faucet, shower.

According to the structure, it can be divided into single, double and triple taps. Single connection type can be connected to cold water pipe or hot water pipe; double type can be connected to cold water pipe at the same time, and it is mostly used for bathroom basins and faucets in kitchen sinks with hot water supply; the triple connection removes cold and hot water. , You can also connect shower heads, mainly used for bathtub faucets. There is also a single handle and dual handle points.

Single handle faucet can adjust the temperature of hot and cold water through one handle; double handles need to adjust the cold water pipe and hot water pipe respectively to adjust the water temperature.

According to the opening method, it can be divided into spiral type taps. When the spiral handle is opened, many circles need to be rotated.

Wrench-type faucets, wrench handles typically rotate 90 degrees.

Raise the faucet and lift the handle to raise the water.

Inductive faucets, inductive faucets, as long as the hand reaches under the faucet, it will automatically water.

According to the valve core, it can be divided into copper valve core, ceramic valve core and stainless steel valve core. The key to the quality of faucets is the valve core. Taps with copper spools are mostly spiral cast-iron taps that have now basically been eliminated; ceramic tap taps have emerged in recent years and are of better quality and are now more commonly used; stainless steel spools have only recently emerged. More suitable for areas with poor water quality.

Purchase

1. Choose the faucet should consider the environmental protection function

With the improvement of living conditions and the improvement of living standards, people have higher and higher requirements for water quality. Therefore, environmental protection and functional faucets are increasingly valued. Some businesses or factories have started to innovate from the perspective of environmental protection and functionality, mainly reducing the lead content of taps to improve water quality.

The valve body of the general faucet is made of bronze and its content is roughly between 54% and 82%. Some high-quality imported faucets can contain up to 85% copper. Besides copper, there are other metal contents if lead is used. An excessively high level of content can be detrimental to human health. The lead content of many faucets on the market is generally 3% to 5%, while the lead content of imported faucets is relatively low. In response to this situation, some manufacturers have developed low-lead faucets. Lead can be less than 0.3%.

In addition to low-lead health and environmental protection leaders, some small additional designs also reflect people's pursuit of functionality. For example, small shower heads equipped with soap dispensers and flushing sinks on both sides of the kitchen faucet, equipped with a special stainless steel filter grille at the outlet of the faucet, can slow the flow of water, block debris in the water, and improve water quality.

2. Buy the quality of the tap before the style in the back

There are many styles of taps, which should be quality first and style second. The tap control handle has a single handle and a double handle. Many consumers think that the single-handle mixer is relatively new and the double handles are out of date. In fact, this is a problem of appearance and does not explain the quality. When purchasing, you should start from the actual situation. Single-handle faucet is characterized by easy control and simple structure. Dual-handle is to adjust the water temperature with both hands, but the style can be suitable for more occasions (such as under-basin faucet, massage cylinder faucet, etc.). When the single-lever faucet is turned on and off, the water pressure will rapidly increase. If the copper content of the product is not high enough to withstand the expansion of the water pressure, it is easily damaged, so when the single-lever faucet is in use, it must be slowly Turn on and off. The double-handle faucet has a large pressure range and the water pressure is slowly released, so this problem does not exist.

3 should pay attention to more to see when buying

First look at the brightness of the surface. The valve body of the faucet is cast from brass. After grinding and polishing, the surface is plated with nickel and chromium. The coating of the regular products has specific technical requirements, and through the neutral salt spray test, there is no rust phenomenon within the specified time limit. So when choosing, pay attention to the luster of the surface, hand touch without burr, no air hole, no oxidation spots.

Followed by gently turning the handle to see if it is light and flexible, with a sense of non-blocking stagnation. Some of the very cheap products, have adopted the quality of the valve core, the technical coefficient can not reach the standard, and their price difference of 3-4 times. So do not set the price as the only standard when purchasing.

Check the various components of the faucet, especially if the main components are tightly assembled. There should be no loose feeling. The valve body and handle of a good faucet are all made of graded brass and have a heavy weight and a sense of dignity.

Identify product tags. General regular goods have manufacturer's brand identity in order to identify and prevent counterfeiting. However, some non-regular products or quality products often only have some paper labels attached, even without any marks. When buying, be sure to look for it.
