Butterfly valve test and debugging and common troubleshooting methods: First, the installation of test and adjustment: 1, this product, whether manual, pneumatic, hydraulic, electric components are strictly debug before leaving the factory, the user should re-sealant performance, should Will be evenly fixed on both sides of the import and export, close the butterfly valve, the pressure on the inlet side, in the export side to observe whether there is leakage, the pipe strength test, the plate should be opened to prevent damage to the sealing pair. 2, Although the products are strictly inspected and tested before leaving the factory, there are also some screwdrivers on the way of transportation. To readjust, pneumatic, hydraulic and so on, please read the instruction manual of the drive unit. 3, (electric transmission disc valve) has been the factory control mechanism Kai, closed stroke adjusted. To prevent the power is turned on the wrong direction, the user first turn on the power, the first open manually to the semi-open position, press the electric switch to check the direction of the disc and valve closing direction can be consistent. Second, the common failure and elimination methods 1, the installation before the road to confirm the performance of our products and media flow arrow is consistent with the movement conditions, and plug the valve cavity clean, does not allow the seals and disc with impurities Foreign bodies, never clean before closing the butterfly plate, so as not to damage the ring. 2, the flange plate supporting the installation of special disc flange recommended, that is HGJ54-91 socket welded steel flange. 3, installed in the pipeline location, the best position for the legislation, but can not flip. 4, the need to regulate the use of traffic, a worm gearbox control. 5, the number of open and close the butterfly valve more, in about two months time, open the worm gear box cover, check the butter is normal, should maintain the right amount of butter. 6, check the connection parts require compression, that is, to ensure that the filler bees sex, but also to ensure flexible stem rotation. 7, metal seal butterfly valve products are not suitable for installation at the end of the pipeline, such as must be installed at the end of the pipeline, the need to take the export distribution flange, to prevent the backlog seals, over. 8, the valve stem to install the use of regular inspection of the valve to check the effectiveness of the use, found that the failure to be ruled out in time.
