Performance test of pneumatic butterfly valve?
The quality of the pneumatic butterfly valve will affect the stability of the vehicle and the service life of other parts. Therefore, the automobile pneumatic butterfly valve needs to be in a good working condition for a long time. What kind of pneumatic butterfly valve is good! We checked it together!
Stop the car after driving 10km on the road with poor road conditions, touch the shell of the pneumatic butterfly valve with your hand. If it is not hot enough, it means that there is no resistance inside the pneumatic butterfly valve, and the pneumatic butterfly valve does not work. At this time, you can participate in the appropriate lubricating oil, and then stop the test. If the shell is hot, it means that there is a lack of oil inside the pneumatic butterfly valve, and you should add enough oil; Otherwise, the pneumatic butterfly valve is invalid. Press the bumper firmly and then release it. If the car jumps 2-3 times, the pneumatic butterfly valve works well. Dismantle the pneumatic butterfly valve to make it stand upright, clamp the lower connecting ring on the bench clamp, and pull and press the shock absorber rod several times with force. At this time, there should be stable resistance. The resistance of pulling upward should be greater than the resistance of pressing downward. If the resistance is unstable or there is no resistance, it may be the lack of oil inside the pneumatic butterfly valve or the valve parts are damaged, and the repair or replacement of parts should be stopped. These three points are often used in the process of inspection!
Don't ignore the inspection of your car's pneumatic butterfly valve, which will bring you hidden trouble, so take action when you see it! Don't hesitate! If you need to reprint this article, please indicate the source!

During the actual commissioning of V-type regulating ball valve, it was found that the throttle orifice on the limestone slurry return pipe was too large, the regulating valve had a dead zone during the commissioning process, and the opening and flow of the regulating valve could not form a good curve, increasing the commissioning workload. If the limestone slurry feed pump is equipped with a frequency conversion motor, the reading problem can be solved well, which can not only realize continuous adjustment of the slurry flow into the tower, but also greatly save costs.
