The pneumatic butterfly valve occupies half of the mechanical operation like the pneumatic ball valve, so how to do the daily maintenance of the pneumatic butterfly valve? Qingdao Jintaiyu Valve Co., Ltd.-a professional manufacturer of pneumatic butterfly valves reminds everyone that the following points should be noted in the daily use of pneumatic butterfly valves:

1. Inspection and maintenance of solenoid valve and silencer

Check and maintain the solenoid valve every 6 months, mainly check whether the solenoid valve is clogged with dirt, whether the movement of the spool is free, whether the silencer is clogged with dirt, whether it is smooth, and whether the air source is clean and free of moisture, etc. .

2. Cylinder inspection and maintenance

Normally clean the surface of the pneumatic butterfly valve cylinder. At the same time, pay attention to the timely refueling of the cylinder rotating shaft circlip, and periodically (basically about 6 months) open the cylinder end cover to check the cylinder for debris and moisture, and pay attention to grease Condition, if the grease is missing or dry, you need to disassemble the cylinder for full maintenance and cleaning before adding grease.

3. Valve body inspection

Every 6 months, check whether the appearance of the valve body is good and whether the mounting flange is leaking. If it is convenient, check the valve body for good sealing and wear. Also check whether the valve plate of the pneumatic butterfly valve is flexible and whether the valve has foreign objects. Stuck.

4. Cylinder block disassembly and assembly methods and precautions

First remove the cylinder from the valve body, and then remove the two ends of the cylinder. When disassembling the piston, be sure to pay attention to the direction of the piston rack, and then use external force to rotate the cylinder shaft clockwise to run the piston to the outermost edge, then slowly vent the valve closing hole, and gently push the piston out with air pressure, but this method must be Be careful to ventilate slowly, otherwise the piston will suddenly eject, which is a bit dangerous! If personal operation is not possible, you can contact the pneumatic butterfly valve manufacturer for assistance.

Then remove the circlip on the cylinder shaft, the cylinder shaft can be taken out from the other end. After removal, clean and grease each part. After the grease is added, it must be installed in the order of disassembly and in reverse order to ensure that the upper slot of the gear shaft is parallel to the cylinder block when the valve is open, and the upper slot of the gear shaft is perpendicular to the cylinder block when the valve is closed.

Pneumatic butterfly valve cylinder block disassembly is actually a technical task. During the dismantling process, you must be cautious. If you cannot do it yourself, please remember to contact Jintaiyu Valve-a professional manufacturer of pneumatic butterfly valves!
