Butterfly valve test and installation and troubleshooting methods

1. Before installation, confirm whether the product performance and medium flow direction arrow of our factory are consistent with the operating conditions, and insert the dry pendulum into the inner cavity of the valve to rotate clockwise. It is not allowed to have impurities on the sealing local magnifying ring and butterfly plate. It is not allowed to close the butterfly plate before cleaning, so as to avoid damaging the sealing ring

2. It is recommended to use special flanges for butterfly valves, i.e. HGJ socket welded steel flanges, for disc plate installation

3. The best position for installation in the pipeline is vertical installation, but it cannot be upside down

4. In use, the flow needs to be adjusted and controlled by a worm gear box

5. For the process parameters of all extrusion processes such as melt pressure and temperature, body temperature of each section, rotating speed of main screw and feeding screw, and butterfly valve with large feeding volume, open the worm gear box cover in about two months, check whether the butter is normal, and maintain an appropriate amount of butter

6. Check that the connecting parts are required to be compressed, which not only ensures the honeybee property of the packing, but also ensures the flexible rotation of the valve rod

7. Metal sealed butterfly valve products are not suitable for installation at the end of the pipeline. If they must be installed at the end of the pipeline, they need to be equipped with outlet flanges to prevent the backlog and over positioning of sealing rings

8. For different types of valves, check the use effect of valves regularly according to the installation and use reaction of different material detection rods, and eliminate faults in time
