The pneumatic butterfly valve is undoubtedly an important part of the car. When the car encounters potholes during driving, it completely needs to rely on the buffering and damping of the pneumatic butterfly valve to ensure the stability and safety of the body. If the buffering link is damaged, it will have a great impact on the driving experience and body safety. The common shock absorber types are hydraulic shock absorber, ball valve shock absorber, shock absorber, air cushion shock absorber, etc. Most shock absorbers on automobiles are hydraulic shock absorbers. On a flat road, you can hear the "gurgling" sound in the front of the vehicle, which is intensified when turning sharply. When stopping for inspection, press firmly on the front of the vehicle.
Make it bounce back up and down, and abnormal noise appears. The greater the force, the greater the noise. The diagnostic vehicle is usually driven on a bad road, and the shock absorber is damaged due to oil leakage due to improper maintenance. Solution: In this case, repair or replace it according to the severity of the damage. Oil leaks from the oil seal on the upper part of the main body of the pneumatic butterfly valve, and once the pneumatic butterfly valve moves, the oil drops more severely. Diagnose the loss of sealing performance due to the damage of the oil seal caused by the damage of the piston rod or the attachment of foreign matters. Solution: In this case, we recommend replacing new parts or new shock absorbers. When starting or braking, the body bumps violently up and down, which makes the passengers feel unstable. Diagnose the aged shock absorber. Solution: We recommend replacing the shock absorber to make the body feel bumpy up and down, reduce small vibration, and make the ride more stable and comfortable. The pneumatic butterfly valve is usually checked every 100000 km. The maintenance cycle of different models may vary slightly. When does your car need to be replaced for maintenance.
