How to distinguish the triangle valve is good or bad?
How to identify the angle valve quality depends on the material and processing technology, the appearance of electroplating, indeed there is a big difference in life, of course, the best choice is the copper forging (forging) can be in more than 10 years, the body will not have trachoma Water Leakage situation; the second is the copper foundry casting 5-8 years, some foundry casting quality is not good and more prone to blisters Water Leakage; zinc alloy 1-2 years, will be very brittle, may be broken into the pipeline and can not be replaced.Choose good copper material, angle valve and faucet is easier to change parts (good quality forged copper angle valve and faucet is not required to replace, only the replacement of ceramic valve can be).
4, look at the triangular valve surface coating process, the process of good coating, surface quality is good, longer use time.(1) generally speaking, the more bright and delicate the surface, the more obvious the mirror effect, the better the coating process, the more the coating, the better the quality;(2) can see the quality of material used to hold methods, some businesses will use cast iron, zinc alloy and other materials as copper, the hardware for two or three seconds after the release, the fog and the traces disappear quickly can be found in the copper, if the mist, lingering traces of material, possibly non copper.[] also called triangle valve, angle valve, angle valve, water mixing valve etc.. This is because the pipe makes a 90 degree corner shape at the angle valve, so it is called a triangle valve.
The way to distinguish the triangle valve:1, look at the weight, weight, light weight, good. On the one hand, the density of copper is greater than the density of iron; on the other hand, the thicker the material, the greater the quality.2, look at the spool: the valve's large aperture than small good, the processing of the thread looks relatively fine.3, look at the material, material performance ratio (from high to low): copper is greater than stainless steel, larger than zinc alloy.(1) the triangle valve made of zinc alloy is the worst and cheapest one. It is usually used in unimportant places or temporary places.(2) the triangular valve made of copper material is of good quality. At present, the process of producing copper triangle valve is red stamping or forging and casting. The triangular valve for distinguishing copper is the process of red stamping or forging and casting: when looking at a triangular valve, it means that the inner side of the interface is connected with the inner spool. If there is a hole, that is, the rough surface is cast. Conversely, it is red or forging.A, red or forging process triangular valve is produced with the entire copper block, the whole body compact structure, the best quality;B, casting process produced triangular valve body may exist cracks, the quality is worse.(3) stainless steel triangle valves are of central quality and price.
