Pneumatic ball valve is intended to improve the ride comfort and warmth of cars. Most cars have pneumatic ball valves installed in their suspension systems. What should be done for the daily inspection of pneumatic ball valves?
1. Stop the car after driving 10km on the road with poor road conditions, touch the shell of the pneumatic ball valve with your hand. If it is not hot enough, it means that there is no resistance inside the pneumatic ball valve, and the pneumatic ball 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 pneumatic ball valve is short of oil inside, and you should add enough oil; Otherwise, the pneumatic ball valve is invalid.
2. Press the bumper firmly, and then release it. If the car jumps 2-3 times, the pneumatic ball valve works well.
3. If the vehicle vibrates violently when it drives slowly and brakes in an emergency, the pneumatic ball valve is faulty.
4. Dismantle the pneumatic ball valve to make it 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 no resistance, it may be the lack of oil inside the pneumatic ball valve or the damage of valve parts, and the repair or replacement of parts should be stopped.
