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.

The baffle plate is corrosion resistant, wear-resistant, and has the function of guiding and maintaining the thermal insulation layer. In order to make the non-metallic contraction joint can reach the application effect in the pipeline, its various mechanical properties can really play a role, and extend its service life, please install the device according to the following requirements:
1. When non-metallic contraction joints are installed in the pipeline, they should be kept in a natural state as far as possible. Do not artificially deform the product during installation, so as to prevent early damage of the product and weakening of the application effect.
2. When the non-metallic contraction joint is connected with the flange, the screw rod of the bolt shall extend to the outside of the flange to avoid the scratch of the thread tip on the rubber (fabric) sphere of the joint during the contraction deformation. The bolts on each flange end face shall be evenly pressurized and tightened one by one. It is required that the tightness of all bolts can be different as far as possible. In places with poor application conditions, spring washers can be added in addition to flat pads, To prevent the nut from loosening.
3. There is a support frame in the middle of the joint. The support frame should be kept in place before the device. After the bolts are tightened, all of them should be knocked off to ensure that the device is reasonable and that its physical and mechanical properties really play a role.
