As the core component of the faucet – the valve core, to a large extent, determines the service life, quality and quality of the faucet. Therefore, to improve the quality of the faucet, the first step is to start from the valve core, and the material of the valve core determines the quality of the valve core. According to the material, the valve core can be divided into rubber valve core (slow-opening valve core), ceramic valve core (fast-opening valve core), ball valve core, stainless steel valve core.
Most of the faucets that use rubber valve cores are iron cast faucets with spiral openings, but they have been largely eliminated. This spool of the faucet life is short, easy to leak.
According to the relevant information, the ball spool was applied in 1960, and the handle of the ball spool faucet is mostly installed only in the middle position. The advantage of this spool is that the stainless steel ball used is resistant to corrosion. In addition, from the point of view of cost savings, the ball can also be made of cheap materials such as plastic. The disadvantage of ball spool faucet is the installation of more accessories, rotation friction resistance, easy to cause the faucet seal failure, resulting in leakage.
Ceramic valve cores, as a new material emerging from technological innovation, are now generally more popular in the market. Its advantages are less water pollution, low price, longer service life, better sealing performance, more economic and environmental protection. In addition, ceramic also has a strong physical stability. In the course of use, can withstand wind, sun, rain, high temperature, low temperature, abrasion resistance, its surface is not easy to erode after corrosion and deformation. These properties of ceramic is an important factor in determining the service life of the faucet. Therefore, the normal service life of ceramic spool is more than 10 years, which is longer than the service life of other spools. The disadvantage of ceramic spools is that they are fragile and prone to breakage. Ceramic is also susceptible to magazine attack in water and has high water quality requirements during use, which limits its range of use.
Stainless steel spool
Stainless steel is another new material for the technological innovation of faucet valve cores. Its focus is on long service life, corrosion resistance, easy to disassemble and clean. Compared with ceramic valve core, its biggest feature is not high water quality requirements, not easy to be eroded by impurities in the water, affecting the service life. Therefore, stainless steel faucet spool is particularly suitable for use in areas with poor water quality. In addition, it is easy to disassemble and wash, and consumers can complete simple maintenance and installation work themselves. However, it also has its drawbacks: more expensive.
Determination of spool
- When adjusting the left and right spools, you can judge by feel. A good spool is “idle” when rotating left and right, feeling light and without resistance.
- Gently hold the handle of the faucet with your index and middle fingers and move it gently up and down, left and right, and observe whether it is flexible and not loose, whether there is a sense of resistance, whether there is a sense of oil resistance, flexible and not loose, no sense of resistance. Oil resistance feels heavy, which means the faucet valve core you choose is a quality product.
