Pneumatic butterfly valve common failures and solutions

pneumatic butterfly valve common failures and solutions
a pneumatic valve, pneumatic butterfly test and adjust the
pneumatic valve, butterfly either manual, pneumatic, hydraulic and electric components are after strict debugging before they go out, the user when the re-inspection sealing performance, import and export shall be uniformly fixed on both sides, closing butterfly pneumatic valve, pressure on suction side, in the export side to observe any leak phenomenon, in front of the pipeline strength experiments, the butterfly plate should be open, to prevent damage to the seal.
, pneumatic butterfly valve before shipment are through strict inspection and experiment, but there are also individual products in transit automatic screw dislocation, to readjust, pneumatic, hydraulic, etc. , please read the accessory drive operating instructions.
, electric drive control pneumatic valve factory has will control institutions opening and closing of the trip. To prevent power on is the direction to make wrong, the user after the first switched on, the first to open the manual to half open position, in the direction of electric switch check dial with pneumatic valve can be closed in the same direction.
2, pneumatic butterfly valve of the common failures and solutions
, before installation to confirm our products performance and whether the medium flow arrow is consistent with the movement conditions, and insert pneumatic valve inner cavity clean, no foreign impurities in sealing ring and disc attached, before cleaning must not be allowed to close the butterfly plate, so as not to damage the sealing ring.
the butterfly, butterfly plate mating flange installation recommended special pneumatic valve flange, HGJ - namely Type socket welding steel flange.
and installation position in the pipeline, the optimal location for the vertical loading, but can't flip. Need to adjust the flow in the
and use of, have to control the worm gear box.
, on and off a lot of pneumatic valve disc, in 2 months time, open the worm gear case cover, check whether the butter is normal, should keep the right amount of butter.
compression, check the connection parts requirements, namely the packing sealing, guaranteeing flexible pneumatic valve rod rotation.
and metal seal butterfly pneumatic valve products are not suitable for installation in the end of the pipe, such as must be installed in the end of the pipe, fittings export flange, should also be taken to prevent the backlog of sealing ring, too.
, pneumatic valve rod installation using regular check pneumatic valve using effect, find fault in a timely manner to eliminate.
