What are the key points of the pneumatic butterfly valve?
In daily use, the maintenance of pneumatic butterfly valves is also a big problem that cannot be ignored. So do you know where the focus of the maintenance of pneumatic butterfly valves is? When the chassis of the car sinks and the car body becomes low, there are usually several reasons: First, the metal fatigue of the spring causes the spring to recover and then reduce its ability; The second is caused by wear, deformation and oil leakage of buffer cylinder and other parts; Third, it is caused by the aging of hydraulic oil; Fourth, it is composed of aging oil seal and oil leakage. One of the important reasons for oil leakage is that the pneumatic butterfly valve core is damaged or rusted. Therefore, when the car falls and is impacted by external force, it is necessary to timely check whether the pneumatic butterfly valve core is deformed and whether the oil seal is damaged. This is to ask whether the pneumatic butterfly valve core can be injured and corroded as the focus of daily care. Pay attention to check whether the oil seal and dust cover of the pneumatic butterfly valve can leak oil, or whether there is dust and dirt attached, and clean the pneumatic butterfly valve core and relevant parts in time to ensure that the pneumatic butterfly valve is free of oil leakage. Assuming that the buffer cylinder of the pneumatic butterfly valve is oxidized and rusted, the grinding can be stopped with metal abrasive to restore its brightness. Also pay attention to check whether the front pneumatic butterfly valve core is scratched or rusted, because this is one of the important reasons for the damage of the pneumatic butterfly valve oil seal and the leakage of hydraulic oil. To check whether there is hydraulic oil leakage in the connecting rod oil seal, if there is leakage, it must be replaced or repaired by a professional. The dirt on the connecting rod of the buffer cylinder must be cleaned with a soft cloth. If it has oxidized and rusted, it should be immediately removed by polishing with metal abrasive. The connecting rod part of the rear wheel buffer cylinder shall be checked for sediment, dirt accumulation, scratches, rust, etc. If there are any of the above conditions, it shall be cleared or repaired in a timely manner.
Have you learned the key points of the home care of pneumatic butterfly valves? Timely maintenance can extend the service life of pneumatic butterfly valves.

4. Conclusion:
After the piston of the hydraulic ring servomotor of the butterfly valve is processed and tested by manual operation, it only takes 15s to open and close the butterfly valve once under no-load condition; In still water, it takes 18~25s to open and close the butterfly valve once, which greatly shortens the opening and closing time. Moreover, the opening and closing process of the butterfly valve is smooth and free, and the hydraulic ring connector has no oil leakage. After the automatic system is formed, the butterfly valve can be closed quickly and reliably when the water guide mechanism is out of control, creating good conditions for the safe and stable operation of the unit.
