Inevitable problems in the inspection of pneumatic butterfly valves?
The pneumatic butterfly valve on the car is more important than the safety of the car, so we should also pay attention to whether the pneumatic butterfly valve can also work normally during the car inspection. In addition to the time of vehicle inspection, we can detect the pneumatic butterfly valve, and in ordinary times we can also stop the inspection ourselves. Next, our personnel of metal pneumatic butterfly valve will sort out some inevitable inspection steps for you:
When the car runs 10 to 15 kilometers on the uneven road, touch the pneumatic butterfly valve housing by hand. If it does not heat up, it indicates that the pneumatic butterfly valve may have lost its shock absorption effect due to lack of oil or damage of main parts. It should be removed for maintenance or replaced with new parts.
The failure or damage of the pneumatic butterfly valve will directly affect the ride comfort and comfort of the car, and will also affect the service life of the car parts. Therefore, the inspection and maintenance of pneumatic butterfly valves are also essential. If there is abnormal continuous vibration during the driving process of the car, carefully check whether the pneumatic butterfly valve can leak oil, and if it does, clean it up.
Check the working condition of the pneumatic butterfly valve when the car is suspended from the secondary home care. The inspection method is: fix the lower end of the pneumatic butterfly valve on the bench clamp, stretch and tighten it several times by hand, the normal pneumatic butterfly valve should have a certain resistance, and the stretching resistance should be greater than the resistance when tightening. If it is unstable or has no resistance, it may be that the pneumatic butterfly valve is short of oil or the parts are damaged. It should be repaired or replaced with new parts.
These are the inevitable problems that we usually check. I hope they can help the car owners. This article is organized by Songxia Xizhen Pneumatic Butterfly Valve Co., Ltd.

Structural analysis of stainless steel pneumatic butterfly valve
One or more layers of steel wire or steel belt net sleeves are made of stainless steel corrugated pipes, and both ends are equipped with joints or flange heads, which are used to escort flexible components of various media.
2、 Features: corrosion resistance, high temperature resistance, low temperature resistance (- 196 ℃~+420 ℃), light weight, small size, good flexibility.
It is widely used in aviation, aerospace, petroleum, chemical industry, metallurgy, power, paper making, wood, textile, construction, medicine, food, tobacco, transportation and other industries. 　
1. Recommend corrosive chemical media or organic solvents. (For example: loading and unloading ammonia, acetone, etc.)
2. Escort high-temperature gas, hot oil and other high-temperature media. (For example: hot steam, heat transfer oil, etc.) 3. Escort low temperature or ultra-low temperature media. (e.g. liquid nitrogen)
4. Water, steam, oil and other media shall be guaranteed under high temperature environment. (For example: water vapor system and hydraulic system in coking, steelmaking and continuous casting equipment) 5. Pipeline requiring shock absorption or noise elimination. (For example: pump inlet and outlet) Specification: ￠ 4 - ￠ 600 Pressure: 0.6MPa-25.0MPa Executive specification: GB/T14525-93
