The 5) butterfly common failures and countermeasures

failure:
sealing leak, pneumatic butterfly valve plate and ring with sundry. , pneumatic butterfly valve plate and seal closed position right is wrong. , exports are equipped with all kinds of flange bolts or clamping force. , the direction of the failure, pressure test requirements. 。
eliminate, eliminates impurities and clean the pneumatic valve cavity. , adjust the worm gear drive restrictions, such as screws or electric actuators. In order to realize the pneumatic valve closed position is correct. , Charles is equipped with flat flange and bolt clamping force should be uniform compression, and the direction of rotation arrow fault:

surface leakage current through a pneumatic valve, both sides of the gasket is broken, the flange or compressed clamping force of inequality.
eliminate:, replace the gasket. , the compression flange bolts ( Even forced) 。 Fault:
