Common butterfly valve fault elimination methods
Common butterfly valve fault elimination methods Cause of failure: leakage of the sealing surface, and sundries are included in the butterfly plate and sealing ring of the butterfly valve. Elimination method: eliminate impurities and clean the inner cavity of the valve. Cause of failure: The butterfly plate and seal closing position of the butterfly valve are not in the right place. Elimination method: Adjust the limit screws of the actuator such as worm gear or electric actuator to achieve the correct closing position of the valve. Cause of failure: The outlet is equipped with flange bolts that are stressed or not compressed. Elimination method: check the flange plane and bolt pressing force, which should be evenly compressed. Cause of failure: The direction of the pressure test is not as required. Elimination method: Install in the direction of the arrow. Cause of failure: Failure of sealing gaskets on both sides. Elimination method: Replace the sealing gasket. Cause of failure: uneven or uncompressed pipe flange compression. Elimination method: compress the flange bolt or re-tighten the bolt with uniform force.
