Pneumatic switch control pneumatic valve maintenance points

maintenance method of pneumatic butterfly valve

, pneumatic butterfly valve in use process, often should keep clean, drive screw thread must be lubricated periodically, found that when a failure, should immediately stop using, find out the reason to remove fault.

and packing gland bolts shall be uniformly tight, should not be pressed into crooked state, in order to avoid collision block pneumatic valve rod movement or cause leakage.

and when installation, pneumatic valve can be according to the connection device in pipeline directly. In general, can be installed on the pipeline at any position, but need to facilitate the maintenance operation, should pay attention to the flow direction of medium by the pneumatic valve is high, the longitudinal aerodynamic disc below lift check pneumatic valve can only be installed horizontally.

, pneumatic butterfly valve, when used only for full open or full close, does not allow for regulating flow, lest sealing surface erosion, accelerated wear and tear. Pneumatic valve and the upper thread by the pneumatic brake valve with pour sealing device, the handwheel back to the top position and tighten, to prevent leakage of media from the packing.

, pneumatic butterfly valve open and close the application at hand, please do not use leverage, or other tools, so as not to damage the pneumatic valve. The handwheel clockwise to shut down, and vice to open it.

and before the installation, should check carefully the pneumatic valve pressure, size is in line with the use requirement, eliminate the defects caused by the transportation process, and eliminate the pneumatic valve piece of dirt.

and long-term storage of pneumatic valves, shall regularly check, for the leakage of the processing surface should be clean, remove dirt, keep the ball on both ends of the pneumatic valve should be blocked and in an open position, pneumatic butterfly valve, the ends of the channel should be blocked and closed, neatly stored in indoor and ventilated dry place, do not heap or in open air.
