Vacuum butterfly valve correct use method introduction

1. When the vacuum butterfly valve is used, it is only used for full opening or full closing. It is not allowed to be used for conditioning and saving, to avoid erosion of the sealing surface and accelerate wear. There is a reverse sealing device in the gate valve and the shut-off valve. When the hand wheel is screwed to the upper direction, the medium can be blocked from leaking from the packing.

2. During the use of the vacuum butterfly valve, it should always be kept clean. The transmission thread should be regularly lubricated. When it is found to be faulty, stop using it immediately and find out the cause to eliminate the problem.

3. The bolts of the packing gland should be evenly tightened, and should not be pressed into a smashing condition to prevent the bump from hindering the movement of the valve stem or forming a leak.

4. Before the equipment, carefully check the pressure of the valve mark, whether the diameter meets the requirements of use, eliminate the shortcomings caused by the transportation process, and eliminate the dust of the valve parts.

5. When the equipment is used, the valve can be directly connected to the pipeline according to the connection method. Under normal circumstances, the equipment can be in the direction of the pipeline, but it needs easy maintenance.

6. Do not rely on levers or other things when opening or closing the vacuum butterfly valve to avoid damage to the valve. The handwheel rotates clockwise to close, and vice versa.

7. The butterfly valve stored for a long time should be checked regularly. The exposed surface should be kept clean and the dirt should be removed. When the storage, the two ends of the pneumatic butterfly valve should be blocked and open, and stored neatly in the indoor and ventilated area. Stacked or open storage.
