What are the flowing characteristics for the water valve equipments?

Shanghai - Shanghai Chamgu valve Co., Ltd which is the professional watervalve.org China water valves manufacturer has devoted into the water valve production for almost 10 years. According to their many years¡¯ experience and current market analysis, the adjustable electric ball valve should be one of the most widely used valves in the water treatment system. The expert has said that the feather of the adjustable electric ball valve could be concluded into the easy installation, simple operation, economical and affordable price. However, the most important feature of this kind of valve equipment should be their flow characteristic. Today, the engineer from Shanghai Chamgu valve which website is www.watervalve.org would introduce with people the flow characteristics about the adjustable electric ball valve.

The flow characteristics of valve is the relationship between the opening degree of valve and the flowing volume as the differential pressure across the valve is kept under constant conditions. The medium flowing characteristic through the valve could be concluded into linear features, equal percentage and parabolic characteristic. The description below should be the detailed meaning for these three characteristics.

The first point which the engineer from WaterValve.org wants to tell people should be the parabolic characteristic which has been provided with the intermediate characteristic of the linear and equal percentage characteristics. From the analysis of all of three characteristics, people can see that the equal percentage characteristic would be best in the regulation performance. Its regulation is very stability and good performance. On the other hand, the regulation performance of the parabolic characteristic should be better than the linear characteristic. However, people should select one of the three flowing characteristic according to the different requirements and occasions.

The second point should be the linear characteristic. The stroke and flowing volume of the linear characteristic could show with people the linear relationship. The change of the unit itinerary would not cause into the flowing change which should be constant. If the actually flow volume is huge, the relative value of flow rate would have little change. If the flowing volume is very small, the relative value of the flow rate would have large changing.

The third point should be the equal percentage characteristic. The relative stroke and relative flowing volume irrigation valve of the equal percentage characteristic has not been shown with the linear relationship. The flowing volume changing which is caused by the itinerary changes of the by every point of the stroke unit has the directly ratio with the traffic of this point. So, this kind of flowing characteristic has the advantage of that the flow change would be small as the little flowing volume. Otherwise, the large flowing volume would cause into the big flowing change.
