Pneumatic butterfly valve factory tutor how to troubleshoot the shortcomings of automotive pneumatic butterfly valve?
Automobile pneumatic butterfly valve has the function of alleviating the impact of the road surface on the vehicle, and quickly absorbing the vibration generated when it is stable. Do you know how to stop the inspection of automobile pneumatic butterfly valve and what operating skills are there? Now let's see the sharing content of Songxia Xizhen pneumatic butterfly valve:? Method 1: Stop the car after driving 10km on the road with poor road conditions, touch the shell of the pneumatic butterfly valve with your hand. If it is not hot enough, it means that there is no resistance inside the pneumatic butterfly valve, and the pneumatic butterfly valve does not work. At this time, you can participate in the appropriate lubricating oil, and then stop the test. If the shell is hot, it means that there is a lack of oil inside the pneumatic butterfly valve, and you should add enough oil; Otherwise, the pneumatic butterfly valve is invalid.
Method 2: Press the bumper firmly, and then release it. If the car has 2 or 3 jumps, it means that the pneumatic butterfly valve works well, otherwise, it is not working well.
Method 3: When the car is running slowly and emergency braking occurs, if the car vibrates violently, the pneumatic butterfly valve does not work properly.
Method 4.
After confirming that the pneumatic butterfly valve has a problem or failure, the first thing to check is whether the pneumatic butterfly valve has oil leakage or traces or phenomena of obsolete oil leakage.
The oil seal washer and seal washer are broken, and the nuts of the oil storage cylinder cover are loose. The oil seal and sealing washer may be damaged and invalid, so the seal shall be replaced with a new one. If the oil leakage still cannot be eliminated, the pneumatic butterfly valve should be pulled out. If the weight is different, further check whether the clearance between the piston and the cylinder barrel is too large, whether the piston connecting rod of the pneumatic butterfly valve is bent, and whether the surface of the piston connecting rod and the cylinder barrel are scratched or pulled. Finally, the pneumatic butterfly valve will make a noise in the theoretical application, which is mainly caused by the collision between the pneumatic butterfly valve and the leaf spring, the frame or the shaft. If the rubber gasket is damaged or scattered, the dust cylinder of the pneumatic butterfly valve is deformed, and the oil is lacking, the reason should be found out and repaired. The normal operation of the pneumatic butterfly valve can ensure that we can travel more smoothly during driving, so it is necessary to check whether the pneumatic butterfly valve works normally in time.

What are the types of stainless steel gold bellows?
From the planning point of view, the metal bellows have two kinds of materials, strip and pipe, which can form annular bellows and spiral bellows.
The annular corrugated pipe is a pipe with special shapes whose outer edge of a number of annular diaphragms is tangent to a number of concave centripetal semicircular rings, and the inner edge is tangent to a number of concave vest semicircular rings. Its blank is mainly pipe material. This type of corrugated pipe has the following characteristics: large flexibility, good elasticity, simple manufacturing and small rigidity. It is suitable for manufacturing pneumatic butterfly valves with large and medium diameters that bear normal working pressure and have high demand for flexibility.
Spiral corrugated pipe is a pipe with special shapes whose outer edge of the spring wound membrane of a certain length is tangent to the spring wound concave centripetal semicircular ring, and the inner edge is tangent to the spring wound concave vest semicircular ring.
This type of bellows has the characteristics of high strength, high rigidity, simple manufacturing, etc., and is suitable for making pneumatic butterfly valves with high and medium pressure, medium and small diameters that have common flexible requirements and high strength requirements.
