Disassembly and assembly methods and precautions of cylinder block
First, remove the cylinder from the valve body. First, remove the covers at both ends of the cylinder. When removing the piston, be sure to pay attention to the direction of the piston rack. Then, rotate the cylinder shaft clockwise with external force to make the piston move to the outside. Then, slowly vent the valve closing hole and gently eject the piston with air pressure. But this method must pay attention to slowly venting, otherwise the piston will suddenly eject, which is a bit dangerous! Then remove the circlip on the cylinder shaft, and the cylinder shaft can be taken out from the other end. Then each part can be cleaned and greased. The parts to be greased are: cylinder inner wall and piston seal ring, rack and back ring piece, as well as gear shaft and seal ring. After adding lubricating grease, install it in the order of disassembly and in the reverse order of position. Pay attention to the position of the gear rack. Make sure that the end groove of the gear shaft is parallel to the cylinder block when the piston retracts to the inside position when the valve is opened, When the valve is closed, that is, when the piston extends to the outside, the end groove on the gear shaft is vertical to the cylinder block.

The product of pneumatic butterfly valve in the new era, the last stop of connector
The product of the new era of pneumatic butterfly valves, the last stop of connectors. Many people still don't understand the pneumatic butterfly valve. Many people haven't better applied the stainless steel pneumatic butterfly valve. From last year to this year, the State Administration of Safety and Quality Supervision has strictly prohibited the passing of liquor through the plastic pipe and rubber hose of the distillery. In the past, in order to reduce costs, the distillery has constantly used plastic pipes to escort liquor, which not only affected the arrival of liquor, but also brought in harmful elements, 304 stainless steel pneumatic butterfly valve soft connection of food pipe has been approved by the Food Monitoring and Quality Committee. It is non-toxic, harmless and non irritating, and will not change any composition of wine. From last year to this year, major wineries have used our stainless steel pneumatic butterfly valve to replace
1. People think that the material of the pneumatic butterfly valve is metal, which is hard, not soft, and not easy to use. I inform you with professional knowledge that the pneumatic butterfly valve has excellent flexibility and a certain bending radius. There is no problem when bending at this reasonable level, and it is not inferior to the plastic pipe
2. It is more durable in service life. We have advanced wave striking equipment (wave striking group equipment). The corrugated pipe body is suitable for applications in various media industries such as industry, chemical industry, pharmaceutical factory, steam, food, etc. It is more suitable to use different wave methods for different structures!
3. Temperature, which breaks through the temperature environment application of plastic hose under normal conditions, good stainless steel pneumatic butterfly valve can continue to work normally under - 140 -+460 ° low temperature and high temperature. This is because the stainless steel metal material itself has the three characteristics of upper and lower temperature performance, which will make the product play a serious role in various industries!
