How to customize a reasonable maintenance plan for metal seat butterfly valve

How to customize a reasonable maintenance plan for metal seat butterfly valve:

1. Keep it clean

Hard-sealed butterfly valves should always be kept clean during use, and the transmission threads must be lubricated regularly.

2. Tighten the bolts

The bolts of the packing gland should be tightened evenly, and should not be pressed into a crooked state, so as to avoid bumps that hinder the movement of the valve stem or cause leakage.

3. Horizontal installation

During installation, the valve can be directly installed on the pipeline according to the connection method. Under normal circumstances, it can be installed at any position of the pipeline, but it needs to be easy to operate and repair. Note that the medium flow direction of the stop valve should be upward from the bottom of the vertical valve disc, and the lift check valve can only be installed horizontally.

4. Inverted sealing device

The handwheel is turned to the upper position and tightened to prevent the medium from leaking from the packing.

5. The handwheel should be used when the hard-sealed butterfly valve is opened or closed. Do not use levers or other tools to avoid damage to the valve parts. Turn the handwheel clockwise to close, and vice versa to open.

6. Regular inspection

Valves that have been stored for a long time should be inspected regularly. The exposed processing surface must be kept clean and the dirt should be removed.Store neatly indoors It is strictly forbidden to stack or store in the open air in a ventilated and dry place.
