how to correctly use, maintenance, adjust the pneumatic diaphragm valve! Pneumatic valve body (1) such as lining anti-corrosion lining, installed on the pipeline, the corrosion resistant cushion should be adopted, and be careful not to make the pneumatic valve flange sealing surface is damaged. (2) the diaphragm storage, should be packed in a bag, put wooden shelves, avoid the sun to be basked in direct and contact with ozone, heap, not with heavy pressure. 。 (3) storage, pneumatic valve is in full open position, ensure no stress state of diaphragm, especially spring shut type pneumatic diaphragm valve more should pay attention to this. Pneumatic valve two flange face shall seal the paper, in case of moisture and dirt from entering. (4) pneumatic valve when use, not too close, once the weir surface pressure pneumatic diaphragm valve body. Pneumatic valve opening speed nor too fast, too fast will load all force on the diaphragm screw, will damage the diaphragm. (5) of the diaphragm and the lining should be checked regularly to prevent corrosion and tearing and damage to other components and cause an accident. 6. Remove and replace the pneumatic valve, fluid on both sides should be cut off, discharge the residual fluid, at the same time do a good job in personnel protective ( Wear protective clothing, masks, gloves, etc. , to prevent corrosive fluid damage to people.
