The faucet product is not durable and soon it is broken. In addition to pushing the responsibility to manufacturers and sellers, consumers do not know that there are many kinds of faucets, especially the selection of valve core materials, which are different in different water quality areas. The faucet is not durable, but it may also be caused by the consumer not being able to purchase it correctly.
As the core of the faucet, the valve plug largely determines the service life, quality and quality of the faucet. Therefore, to improve the quality of the faucet first start with the spool, the material of the spool determines the quality of the spool. Spool according to the material, can be divided into rubber core (slow-open valve core), ceramic valve core (quick-open valve), ball valve core, stainless steel valve core and so on.
Rubber spool
The taps that use rubber valve cores are mostly spiral iron taps that have been turned on, but they have basically been eliminated. This type of spool has a short service life and can easily cause water leakage.
Ball valve core
According to relevant information, ball valve cores began to be used in 1960, and the handles of most ball valve faucets can only be installed in the middle position. The advantage of this type of spool is that the stainless steel ball used has corrosion resistance; in addition, from the perspective of cost savings, the ball can also be made of inexpensive materials such as plastic. The disadvantage of the ball valve faucet is that there are many accessories installed, and the frictional resistance is large, which can easily cause the failure of the faucet seal and lead to water leakage.
Ceramic valve core
As a new material emerging from technological innovation, ceramic valve cores are currently popular in the market. Its advantages are less pollution to water quality, lower price, longer service life, better sealing performance, and more economical and environmental protection. In addition, the physical stability of ceramics, in the use of the process, more able to withstand the wind and sun, rain, high temperature, low temperature, wear resistance; and its surface after a variety of erosion, not easy to be corroded and deformation . These properties of ceramics are important factors in determining the service life of the faucet. Therefore, the ceramic valve core is normally used for more than 10 years, which is longer than other spools. The disadvantage of the ceramic valve core is that the texture is fragile and easily broken; the ceramic is also easily attacked by magazines in the water, and the water quality is required when it is used, which also limits the scope of its use.
Stainless steel valve core
Stainless steel is another new material after the science and technology innovation of faucet valve core. Its focus is on long service life, corrosion resistance, and easy disassembly and washing. Compared with the ceramic valve core, its greatest feature is that it does not require high water quality, and it is not easily eroded by impurities in the water, affecting its service life. Therefore, stainless steel faucets are particularly suitable for areas with poor water quality. In addition, it is easy and convenient to remove and wash, so that consumers can complete simple repair and installation work by themselves. However, there are also drawbacks, that is, the price is more expensive.
Long use and no rusting do not fully represent the good or bad of a faucet. In recent years, there has been frequent incidents of metal poisoning in the kitchen due to excessive use of water in the kitchen and toilet, which has also caused everyone to pay attention to the safety of the tap. For taps, in addition to paying attention to its durability, more attention should be paid to its impact on human physical and mental health. The influence of the faucet on human health comes from the material of the valve core on the one hand, and the overall material of the faucet on the other hand. After the "lead over-standard event" in 2013, the faucets currently on the market are mostly made of brass. But no matter which kind of material, it will contain certain heavy metals. Therefore, the national relevant standard "GB 18145-2014 ceramic chip sealing nozzle" also has a clear stipulation on the restriction of heavy metal precipitation in the tap.
So, how do consumers buy the right taps for the market?
Spool judgment
1, when the valve around the switch adjustment, it can be used to determine the feeling. When a good valve core rotates around, it is "idle", and it feels light and there is no resistance.
2, with the index finger, middle finger gently grip the handle gently move up and down about the left and right, to see if it is not loose, there is a sense of blocking, whether there is oil damping feel, flexibility is not loose, without blocking the touch and there A heavy oil dampening feel indicates that your choice of faucet spool is a good product.
Material grasp
A look at the surface
Resolving a faucet depends on its brightness. The smoother and brighter the surface, the better the quality.
Listen to sound
A good faucet is an overall cast of copper, which sounds boring; if the sound is brittle, it must be stainless steel, and the quality will be worse than a grade.
Three markers
General regular goods have manufacturer's brand logos, and some non-regular products or some quality products often only stick some paper labels, and even without any mark.
