Nowadays, the use of various butterfly valve products has become an indispensable part of industrial production, but in daily use of these butterfly valve products, such as electric butterfly valves, pneumatic butterfly valves, pneumatic control valves, etc., there are often many problems that need to be solved urgently, Today, the manufacturer of pneumatic butterfly valve will talk about the daily regular maintenance of pneumatic butterfly valve to ensure its longevity. 　　

Pneumatic ball valve In advance preparation before installation of pneumatic ball valve
1、 Ensure that the pipeline at the installation site of the pneumatic pipeline ball valve is on the same axis, and the two flange plates on the pipeline should maintain parallel planes. Make sure that the pipeline can bear the net weight of the pneumatic pipeline ball valve itself. If it is found that the pipeline can not bear the net weight of the pneumatic pipeline ball valve, configure the relative support points for the pipeline before installation.
2、 Determine whether there is residue, welding penetration, etc. in the pipeline, and be sure to purge the pipeline clean.
3、 Check the factory nameplate of the pneumatic pipeline ball valve, and carry out multiple actual operations of opening and closing the pneumatic pipeline ball valve to ensure that the valve can work normally. Then check every key point of the valve in an all-round way to ensure that the valve is intact.
4、 Remove the maintenance covers on both sides of the valve, check whether the valve body is clean, and clean the inner wall of the valve body. Because the protruding surface of the pneumatic pipeline ball valve is spherical, even slight dirt will cause damage to the protruding surface. The principle of pneumatic ball valve is to make the valve smooth or narrow by rotating the valve.
