Adjust the flow characteristics of pneumatic valve

pneumatic valves at both ends of a constant pressure, the relative flow through pneumatic control valve and the relationship between the opening to the outside of the medium flow. （ ） Special percentage xing (such as Logarithmic) , as well as other special XingZhongFeng ratio, rather than a linear relationship between relative flow, a day of travel press unit in the traffic flow changes caused by the percentage of the dots is proportional to the flow rate change is the same. So it has the advantage of transportation time, small flow changes, large flow, the flow changes, namely different open, and has the same accuracy. （ ） Line is particularly happy, Line xing) Special interest between a linear relationship with relative stroke and the relative flow line. Unit trip caused by the changes in the flow rate change is eternal. In relative value, traffic flow, traffic, traffic flow relative small changes. （ ） Parabola two states special xing to travel widely, such as special change in the special period percentage line cheerfully. Can be seen from the analysis of the three, especially in the regulation of special liu2 xing xing for the best, its regulation and stability, can very good to adjust equal percentage. Parabolic line special happy than happy special regulation can be turned off, and can according to the different requirements of usage situation, choose any special traffic.
