Pneumatic butterfly valve how to use the maintenance of longer life

pneumatic butterfly valve is widely used in pneumatic valves of a pneumatic valve, general usage, are common in many pneumatic pipeline, therefore, reasonable maintenance, can not only improve the work efficiency, also can reduce the maintenance time, saving the cost of replacement. Want to make the pneumatic butterfly valve stable performance and long service life, suggested that pay attention to the following factors.
one, before use, application of water to clean pipes and pneumatic valve flow section, in case the remaining scrap iron and other debris into the pneumatic valve body cavity.
2, pneumatic butterfly valve in the closed state, the pneumatic valve body still remain part of the media, are also under certain pressure. Before maintenance butterfly pneumatic valve, turn off butterfly pneumatic valve before cut off the pneumatic valve, open the need to overhaul the pneumatic butterfly valve, completely release the internal pressure pneumatic valve body. If it is electric pneumatic pneumatic butterfly valve or pneumatic butterfly valve, should first disconnect the power supply and air supply.
3, soft seal butterfly pneumatic valve are commonly use or four fluorine rubber as the sealing material, hard seal butterfly pneumatic valve sealing surface surfacing welding of metals. If you need to butterfly pneumatic valve cleaning, need to be careful to prevent damaged during disassembly leak sealing ring.
4, flange butterfly when disassembling pneumatic 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.
5, pneumatic butterfly valve remind if the pneumatic valve and clean, you should use a solvent and to clean the parts do not conflict, no corrosion. If is gas special pneumatic ball valves, pneumatic butterfly valve, gas cleaning are available. 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.
6, 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.
7, in open air for a long time, can lead to a 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.
