Most shock absorbers used in the car suspension system are hydraulic shock absorbers. Their operating principle is that the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity flows from one cavity to another repeatedly through different pores.
At this moment, the conflict between the hole wall and the oil and the internal conflict between the oil molecules form a damping force on the vibration, and then reach the role of the valve.
Therefore, the oil inside the hydraulic pneumatic butterfly valve keeps running from one cavity to another. What if it accidentally "leaks sideways"? Don't worry, let's take a look at the structure of pneumatic butterfly valve. In order to ensure that the oil does not leak, the oil seal is a very competent "guard".
Obviously, from the perspective of structure and operating principle, the simple damage to the pneumatic butterfly valve is the oil seal of the pneumatic butterfly valve. After the oil seal is damaged, the oil in the pneumatic butterfly valve will leak and the valve will fail. Therefore, pay attention to the following points in the process of ordinary use:
1. Slow down when the road surface is poor, such as crossing ditches and ridges. Especially when the road conditions are relatively poor, the piston bottoming of the pneumatic butterfly valve may be caused by rapidly passing through the potholed road, which may cause damage to the pneumatic butterfly valve.
2. Prevent heavy objects from being placed in the trunk for a long time. Generally, the pneumatic butterfly valves of four wheels have been adjusted to the best condition. When heavy goods are placed in the trunk for a long time, the rear wheel valve is under heavy pressure, and the oil seal is stressed, which may lead to the possibility of oil leakage.
3. Prevent the vehicle from being parked at an angle for a long time. Some cities may have tight parking spaces in residential areas, so many car owners park their cars beside the road. In order to make more space for the road, most car owners will choose the wheels on one side to ride on the curb, which will make the whole car high while low. The uneven force will also cause damage to the pneumatic butterfly valve.
4. Check the pneumatic butterfly valve regularly. Generally, the pneumatic butterfly valve should be checked every 20000 kilometers to see if there are any problems such as oil leakage and failure. When checking, press the bumper firmly, and then release it. If the car bounces 2-3 times, it indicates that the pneumatic butterfly valve works well.
Pneumatic butterfly valve is not only related to riding comfort, but also to driving safety at high speed. Protect and maintain the pneumatic butterfly valve to form a daily habit!
