Notes for installation and use of butterfly valve:
1. Before installation, confirm whether the performance of our products and the arrow of the flow direction of the medium are consistent with the movement conditions, and the inner cavity of the valve should be inserted and cleaned. No foreign matter attached to the sealing ring and butterfly plate is allowed. Never do it before cleaning. It is allowed to close the butterfly plate to avoid damaging the sealing ring.
2. It is recommended to use the special flange for the butterfly valve, that is, the HGJ54-91 socket welding steel flange, as shown in Figure 3.
3. The position of installation in the pipeline, the best position is vertical installation, but not upside-down installation.
4. It is necessary to adjust the flow during use, and it is controlled by a worm gear box.
5. For the butterfly valve with many opening and closing times, open the worm gear box cover in about two months to check whether the butter is normal. Keep a proper amount of butter.
6. Check the tightness of each connection part, which not only guarantees the bee-like nature of the packing, but also ensures the flexible rotation of the valve stem.
7. The metal-sealed butterfly valve is not suitable for installation at the end of the pipeline. If it must be installed at the end of the pipeline, it needs to be equipped with an outlet flange to prevent the backlog of the seal ring and over-position.
8. Valve stem installation and use response Periodically check the valve use effect, and promptly remove any faults found.
