Pneumatic ball valve common sense make stable performance of installation and maintenance and maintenance

Before using, application of water to clean pipes and pneumatic valve flow section, to prevent the residual iron filings and other debris into the pneumatic valve body cavity. Pneumatic ball valve in the closed state, the pneumatic valve body still remain part of the media, are also under certain pressure. Before you repair pneumatic ball valve, pneumatic valve shut off ball before cut off the pneumatic valve, open the need to overhaul the pneumatic ball valve, completely release the internal pressure pneumatic valve body. If is electric pneumatic ball valve or pneumatic ball valves, you should first disconnect the power supply and air supply. General soft sealing ball four fluorine pneumatic valve are used ( PTFE） As a sealing material, hard seal ball pneumatic valve sealing surface surfacing welding of metals. If you need to clean pipe pneumatic valve ball, need to be careful to prevent damaged during disassembly leak sealing ring. Disassembling flange pneumatic ball valve, flange bolt and nut should be fixed, and then all the nut is a bit tight, and finally fix hard. As to individual nut to fixed good, then other nut, flange surface between pad surface caused by uneven in the damaged or broken, pneumatic valve flange butt out medium leakage. If the use of pneumatic valve and clean, the solvent must cleaning accessories do not conflict, and no corrosion. If it is gas special pneumatic ball valve use gasoline to clean. Other parts generally clean with water can be. When cleaning, thoroughly clean traces of dirt, grease and other attached objects, such as not clean with clear water, can be on the premise of not damage the pneumatic valve body and component, specific detergent for cleaning with alcohol, etc. After the completion of the cleaning detergent such as volatilization completely before assembly. If in use process of filler has a small leak, can be a little to pneumatic stem nut, stop can be close to leak, do not continue to tighten. In open air for a long time, can lead to pneumatic valve body and component rust, can't normal use. Pneumatic ball valve to deposit should be rain, waterproof, moistureproof, and flange cover tightly. Stored for more than a month of pneumatic valves, when using, should be test again, in order to ensure stable performance.
