Pneumatic butterfly valve is a favorite of modern science and technology?
Pneumatic butterfly valve is a favorite of modern technology:
More and more attention has been paid to the deployment of the shock absorber, and it has begun to play an insignificant role. From the perspective of high and new technology, vibration damping has a very high scientific and technological content, which can apply the technology developed from time to time, so that many projects will be stopped under more satisfactory conditions, so that more equipment can extend the service life in a more stable environment and ensure the safety of operation. The prosperity of an industry depends on the number of enterprises in this industry increased in recent years. There is no doubt that the shock absorber industry is a new favorite of modern technology.
After the pneumatic butterfly valve is searched and repaired, the task performance shall be carried out on the special platform. The resistance of its stretching stroke and tightening stroke shall conform to the rule, when the resistance frequency is 100&# 177; 1mm. The abnormal foundation of pneumatic butterfly valve was revealed. Remove the pneumatic butterfly valve and erect it. Pull and press the shock absorber rod several times, and clamp the lower connecting ring on the bench clamp. At this time, there should be constant resistance, and the resistance of upward pulling should be greater than that of downward pressing. If the resistance is unstable or no resistance, it may be due to the lack of oil inside the pneumatic butterfly valve or the damage of valve parts, and the repair or replacement of parts should be stopped. Check whether the pneumatic butterfly valve can leak oil or has traces of obsolete oil leakage. Verify that the pneumatic butterfly valve has problems or fails. The oil seal washer and seal washer are broken. Replace the seal with a new one. Assuming that the oil leakage cannot be eliminated as usual, the nuts of the oil storage cylinder cover are loose. It may be that the oil seal and sealing washer are damaged and invalid. The pneumatic butterfly valve shall be pulled out. If it feels stuck or different in weight, further search 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. If the pneumatic butterfly valve does not leak oil. The pneumatic butterfly valve shall be further synthesized, and the bushing shall be checked for damage, desoldering, splitting or scattering.
If the above inspection is normal. Search whether the fit clearance between the piston and the cylinder barrel is too large, whether the cylinder barrel is strained, whether the valve seal is good, whether the valve clack and valve seat fit tightly, and whether the extension ball valve of the pneumatic butterfly valve is too soft or broken. Follow the pattern of grinding or replacing the pneumatic butterfly valve connecting pin, connecting rod, connecting hole, and condition. In addition, this is mainly due to the collision between the pneumatic butterfly valve and the steel plate ball valve, the frame or the shaft. The pneumatic butterfly valve will present the disadvantage of making a noise in the theoretical monopoly. If the rubber pad is crushed or missing, the dust cylinder of the pneumatic butterfly valve is deformed, and the oil is lacking, the cause should be found out and repaired.
