The electric butterfly valve used in the car suspension system is mostly hydraulic electric butterfly valve. Its operating principle is that the piston in the electric butterfly valve moves up and down, and the oil in the electric butterfly valve cavity flows from one cavity to another through different pores repeatedly.
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 electric 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 the electric 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 electric butterfly valve is the oil seal of the electric butterfly valve. After the oil seal is damaged, the oil of the electric 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, fast passing through the potholed road may constitute the piston bottoming of the electric butterfly valve, which may cause damage to the electric butterfly valve.
2. Prevent heavy objects from being placed in the trunk for a long time. Generally, the four wheel electric butterfly valves have been adjusted to the best condition. When heavy goods are placed in the boot for a long time, the rear wheel valves will be under heavy pressure, and the oil seal will be forced, which will 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 vehicles 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 vehicle high while low. The uneven force will also cause damage to the electric butterfly valve.
4. Check the electric butterfly valve regularly. Generally, the electric butterfly valve should be checked every 20000 km 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 to 3 times, it indicates that the operation of the electric butterfly valve is excellent.
The electric butterfly valve is not only related to riding comfort, but also to driving safety at high speed. Protect and maintain the electric butterfly valve to form daily habits!
