First of all, let's talk about how the flange butterfly valve should be stored before use. Storage of flanged butterfly valves: the flanged butterfly valves before installation and use should be stored in a dry warehouse, and the blocking caps at both ends of the passage should not be removed at will; the butterfly valves with a long storage time should be cleaned, blown dry, and coated with anti-rust oil on a regular basis , And then both ends are sealed with the original plug caps to ensure that the inner cavity is clean and the sealing surface is protected. After talking about storage, let's take a look at the use and maintenance of flanged butterfly valves.
If the flange butterfly valve needs to be used to adjust the flow rate, adjust the opening position of the drive device for control; for the flange butterfly valve with frequent switching times, the worm gear box cover should be opened within 3 months to check whether the butter is normal. Keep a proper amount of butter; after the butterfly valve is installed and used, the effect of the valve should be checked regularly, and if a malfunction occurs, it should be eliminated in time.
