What happens to electric butterfly valves?
There is no doubt that the electric butterfly valve is an important part of the car. When the car encounters potholes during driving, the complete demand is to rely on the buffering and damping of the electric butterfly valve to ensure the stability and safety of the car body. If the buffering link is damaged, it will have a great impact on the driving experience and safety of the car body. Common types of electric butterfly valves include hydraulic electric butterfly valve, butterfly valve electric butterfly valve, electric butterfly valve, air cushion electric butterfly valve, etc. The electric butterfly valves on automobiles are mostly hydraulic electric butterfly valves.
1. On the flat road, you can hear the "gurgling" sound in the front of the vehicle slightly, and the sound will intensify when turning sharply. When stopping for inspection, press the front of the vehicle firmly to make it bounce up and down, and the abnormal sound will appear. The greater the force, the greater the noise.
Diagnosis 1: The electric butterfly valve is damaged due to oil leakage due to improper maintenance when the vehicle is usually driven on bad roads.
Treatment plan: The repair or replacement shall be stopped depending on the severity of the damage.
2. Oil leaks from the oil seal on the upper part of the main body of the electric butterfly valve. Once the electric butterfly valve moves, the oil drops more violently.
Diagnosis 2: The oil seal is damaged due to the damage of the piston rod or the attachment of foreign matters, which results in the loss of sealing performance.
Countermeasures: In this case, we propose to replace new parts or new electric butterfly valves.
3. When starting or braking, the body moves up and down violently and steadily, which makes the passengers feel unstable.
Diagnosis 3: The electric butterfly valve is old and aging.
Treatment plan: we propose to change the electric butterfly valve to make the car body feel stable from top to bottom, reduce small vibration, and make the ride more stable and warm.
The electric butterfly valve is usually checked every 100000 km, and the maintenance cycle may be slightly different between different models. Please understand the function of "self-service maintenance" when your car needs to be replaced.
Note: It is better to change two electric butterfly valves at one time when changing them. If one front or rear electric butterfly valve has a problem, it is necessary to change the two front or rear electric butterfly valves with one steam valve. Because when you change one, the balanced force of the car is uneven, which will lead to different force on the electric butterfly valve, and even more electric butterfly valve problems!
