The principle of spray valve is: using the special structure of spray valve, and then connecting with atmospheric pressure, it can atomization glue into mist so as to achieve the spray effect. There are two kinds of structures, fan and circle, and the fan sector is large. It is covered by the circle, and the circle is small in scope and dense in coating. Each has its own characteristics, and its effect is different.
The principle of spray valve is also very simple. The structure is well done. There are several different materials at present, for example: aluminum alloy + stainless steel, all stainless steel, there are many kinds of stainless steel spray valves. The price is high, and the effect is good. Manufacturers can choose according to the requirements of use. Save trouble, often use can choose all stainless steel, general requirements, choose aluminum alloy and stainless steel, all stainless steel is 304 stainless steel, hardness is very enough.
Stainless steel spray valves meet the viscosity of 3000 and below, can be fully atomized, and then high viscosity will have water droplets, which is not conducive to atomization effect, for spray valve principle must understand, the use of effect can be played out, the effect of stainless steel spray valve is really better than the general spray valve effect!
