Regular maintenance of the electric ball valve mainly includes various preparations before assembly, assembly of the pneumatic pipe ball valve, inspection after assembly of the pneumatic pipe ball valve, maintenance of the pneumatic pipe ball valve, etc. Since the valve surface is often exposed to flowing media, it is easy to produce a large number of rust spots, and the inspectors need to conduct structural analysis of the rust spots, The source of rust spots can be finally found through field experimental analysis such as color printing experiment and heat treatment experiment, which is mainly due to the exposure of carbonaceous substances in valve materials, which leads to the chromization of valves, gate valves, stop valves and spherical valves, and finally produces a large number of rust spots.

Now, when producing and manufacturing pneumatic high pressure ball valves, we often take measures to prevent secondary pollution. Even if there is pollution, we will adopt new technologies and methods to minimize the impact on the environment and people through technical improvement. For example, for a flange, in order not to hurt his hands during production, the head of the connecting bolt of the flange is generally designed as an arc, which is the embodiment of people-oriented.
