Performance test of electric butterfly valve?
The quality of the electric butterfly valve will affect the stability of the vehicle and the service life of other parts. Therefore, the electric butterfly valve needs to be in a good working condition for a long time. What kind of electric 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 electric butterfly valve with your hand. If it is not hot enough, it means that there is no resistance inside the electric butterfly valve, and the electric 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, the electric butterfly valve is short of oil, and you should add enough oil; Otherwise, the electric butterfly valve is invalid. Press the bumper firmly and release it. If the car jumps 2-3 times, the electric butterfly valve works well. Dismantle the electric butterfly valve and erect it, clamp the lower connecting ring on the bench clamp, pull and press the valve 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 no resistance, it may be the lack of oil inside the electric 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!
