What are the general situations of pneumatic butterfly valves?
The pneumatic butterfly valve is undoubtedly 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 pneumatic 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 shock absorber types include hydraulic shock absorber, spring shock absorber, rubber shock absorber, air cushion shock absorber, etc. Most shock absorbers on automobiles are hydraulic shock absorbers.
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 shock absorber 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 pneumatic butterfly valve. Once the pneumatic 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 shock absorbers.
3. When starting or braking, the body moves up and down violently and steadily, which makes the passengers feel unstable.
Diagnosis 3: the shock absorber is old and aging.
Treatment plan: We propose to change the shock absorber to make the car body feel stable up and down, reduce small vibration, and make the ride more stable and warm.
Normally, the pneumatic butterfly valve is checked every 100000 km. There may be a slight difference in the maintenance cycle 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 shock absorbers at one time when changing them. If one front or rear shock absorber is faulty, it is required to change the front or rear shock absorber with one steam damper. Since the car is under uneven balanced force when changing one, the shock absorber will be under different force, which will lead to shock absorber problems!

How to clean the hose?
As one of the important components connecting various components in modern engineering technology, it is mainly used as wire and cable maintenance tubes and civil shower hoses for wires, cables, automatic instrument signals, with specifications ranging from 3mm to 150mm. No matter what kind of pneumatic butterfly valve product, in order to make the hose work better and extend the service life, we should follow the following methods when stopping cleaning:
First, remove the accumulated dust and debris from the hose with a toothpick; Second, when the debris on the hose is removed, we should stop wiping with a wet and twisted dry cloth; Third, place the cleaned hose in a ventilated environment and dry it in the sun. Remember not to expose it in the sun.
